The proposed transmission line will initially have one 115kV transmission line. The corridor will be prepared for the installation of two additional 115 kV transmission lines that will be installed in the near future. 2. The Christopher Substation property is located at 1002 37'h Street NW, Auburn, WA. The proposed transmission line corridor crosses the following parcels: 2895550060, 2895550040, 2895550030, 2895550120,2895550140,2895550130;2895550070,2895550340,2895550010,2895550110, 2895550090,2895550080,2895550050,2895550020,2895550100,1580600021,1580600023, 1580600095, 1580600090, 158Q600060, 0221049062, 1580600023, 0221049038; 0221049062, 0221049054, 0221049180,. 0201049049, 0221049216, 0221049108, 0221D49165, 0221049027, 00221049034, 289555TRCT, and 0221049218. 3., . The Christopher Substation property is zoned M-1, Light Industrial, and the transmission corridor is zoned M-1, Light Industrial, R-1 (1 du/acre), and R-5 (5 du/acre). A utility substafion and associated transmission lines require a conditional use permit within all three zoning designations. 4. The corridor comprising the initial proposed 115kV transmission line and two future 115kV transmission line will begin at the westem portion of the existing substation yard and continue,north ! for 150 feet to a single wood pole antl then continue west for about 180 feet to a three-pole wood structure. The corridor will next tum south/southwest for about 550 fee# fo another three-pole wood structure, after which the wilP continue southwest of SR -167 to a single steel pole (approximately 98 feet tall) located approximately 200 feef east of the West Valley Highway. The corridor is proposed to span Wesf Valley Highway via a 1,000 foot span to a finro=pole wood structure and continue on ,wood . pole structures in the same general direction for about 3;300 feet, before turnina due west and following South 304th Street for another 2,700 feet to the project terminus at 51 Avenue South. The future 115kV transmission lines and inch diameter fiber optic line will occur in the same corridor alignment. The fiber optic li:ne is to,control the electrical system and is used only by Puget Sound Energy. Substation work will include the installation of five new foundations to accommodate the new steel termination pole, bus suPports, and switch stands. This work will be accomplished within the current configuration of f the existing substation yard, so no expansion of this facility is required. 5. Total anticipated excavation work related to new wood pole installations will consist of approximately 60 cubic yards and 50 cubic yards for the excavation for the steel pole foundation. Excavation for the new foundation within the existing : substation yard will include the removal and export of approximately 20 yards. Total grading will be approximately 130 cubic yards. 6. The proposed use is consistent with the Light Industrial zoning designation specified in Ghapter 18.32 of the Aubum City Code. The proposed transmission corridor does eztend into residentially zoned property. Pursuant to Section 18.32.040.C of the Aubum City Code, utility facilities and substations may be permitted within residential zones subject to condifional use permit approval. 7. The M-1, R-1, and R-5 zones' development standards including setbacks and lot requirements are contained in ACC 18.07.030 and 18.32.050. The proposal is in compliance with these regulations - 8. The substation property is within the City's Water and Sanitary sewer service area. A portion of the transmission line corridor is also within the Lakehaven Utility District for water and sanitary sewer. Page 3 of 12 ' Agenda Subject: Puget Sound Energy Christopher Su6station to 51st Date: March 1, 2011 . Avenue South Transmission Line 9: The proposed project entails significant tree removal within fhe 100-200 wide foot transmission line corridor to provide clearance for the lines. Approximately 700 trees will be removed from the transmission line corridor. The trees to be cleared mainly consist of second-growth western red cedars, red alders; black cottonwoods, Douglas-firs, maPles, westem hemlocks, and pines. The goal of the tree removal in the transmission line corridor is to remove large, probfem tree species and develop lower growth from plant communities cflmposed of low growing shrubs and small-scale _ trees. The maximum mature height of plants in the 115kV transmissian line right-of-way is 25 feet. A total of 1,194 trees and shrubs`will be replanted within the corridor; 268 within the landslide and erosion hazard area and 926 within the wetland and wetland buffer areas. 10. Pursuant to ACC Ghapter 15.74 and City of Aubum Design Standards, a temporary erosion and sediment control plan is required to be approved and implemented on the site prior to and during site development. Potential significant adverse environmental impacts :associated with erosion and sedimentation from this development is-adequately mitigated through compliance with this regulation and mitigation measures outlined in this determination. 11. The applicant has also filed an application for a special exception for public agencies and utilities from the City's critical area regulations pursuant to.Aubum City Code 16.10.170 for construction within a Class IV Landslide Area and Geologic Hazard Area. 12. The Federal Aviation Administration issued a"Detecmination of No Hazard to Air Navigation" on December 16, 2008 for the proposed 115kV transmission line corridor. The applicant shall notify the FAA through Form 7460-2, Notice of Actual Construction of Alteration, within 5 days after the construction reaches its greatest heighf. 13. A Notice of Application was issued on November 6, 2009. The Gity received seven comment letters on the project (Exhibit 5). Modifications to the proposal were made were applicable based on the comments received. 14. Pursuant to 18.64.020(B) the Cify ofiAubum Hearing Examiner is authorized to conduct a duly noticed public hearing and render a final decision on a conditional use permit application. The Hearing Examiner's decision is appealable to the Superior Court of the applicable county government. 15. The public hearing was duly noticed with the public hearing noticed published on February 22, 2011 in the Seattle Times, af lead 10=days prior to the public hearing date of March 9, 2011. ?he notice was also posted on site and mailed to adjacent property owners (Exhibit 6). ' 16: In accordance with ACC 18.64:030.C, the site. plan shall be adopted and made part of the permit. Subsequent building permits and construction activity shall be in accord with the approved site plan. The site plan is included as Exhibits 4 and 9. , 17. Based on the current FEMA maps,,the site contains 100-year floodplain associated with Mill Creek. The filled and graveled yard of the.substafion is higher than the surrounding area and surveyed at 47.75 feet median sea level (MDNS SEP06-0032). The proposed transmission line corridor and pole installation do not create additional impervious surfaces that will impact the 100-year floodplain of Mill Creek. 18. A Mitigated Determination of Non-Significance was issued on November 24, 2010 with an appeal period ending December 30, 2010. The City received one comment letter from the Muckleshoot Indian Tribe and their comment has been incorporated into the tevised conceptuaf wetland mitigation plan. No appeals were filed (Exhibit 7). Page 4 of 12 . , ~ . ~ Agenda Subject: Puget Sound Energy Christopher Substation fo 51tt Date: March 1, 2011 • Avenue South Transmission Line CONCLUSIONS: ACC Chapter 18.64.040 provides certain criteria for approval of a Conditional Use Permit: 1. The use will not have a substantively greater adverse effect on the health, safety or comfort of persons living or working in the area and will not be substantively more injurious, economically or otherwise, to property or, improVements in the surrounding area than would any use generally permitted in the district Among matters to be considered are traffic flow and control, access to and circulation within the property; off-street parking and loading, refuse and service area, utilities, screening and buffering, signs, yards and other open spaces, height; bulk, and location of structures, location of proposed open space uses, hours and manner of operation, and noise, lights, dust, odor, fumes and vibration. Staff Comment - PSE "is required to provide reliable electrical power to customers within its service territory (WAC 480- 100-123, RCVV 80.28.110). As growth . has and continues to occur within both rural and urban settings, PSE is required to respond fo the increase in electrical demand by constructing new distribution, transmission, and transformation facilities.. The presence of electrical lines is part ofthe general infrastructure found in developed portions of counties and cities. Distribution of electrical power is required for developed areas and therefore should be considered a compatible land use. PSE identified the need for a substation and associated transmission lines in the Aubum area in the mid-1960s. The Christopher Substation was originally constructed in the early 1980's to address the growth within the Auburn-Federal Way area which included the plans for the proposed transmission line corridor from fhe substation fo 51st Avenue South. The substation site was purchased in 1965 and the acquisition of property rights for the transmission line corridor began in 1966. The corridor • acquisition activities continued through 1981 when the last remaining segments were acquired through condemnation. During the condemnation process, 'PSE had to demonstrate to the court that the project was necessary and fhat it was in the public's interest: Table 1 included in Exhibit 15 provides a list of the parcels located along the corridor wherein PSE has maintained property rights, . as well as the dates of when and howthe rights were acquired. This power line corridor has been in ezistence before many ofithe homes along the route had been constructed. Much of the area has been developed around the utility line corridor. One identified impact on the surrounding area is the new transmission corridor will require significant ttee removal. To mitigate these impacts, approximately a total of 1,190 trees and shrubs will be replanted within the corridor; 268 within the landslide and erosion hazard area and 926 within the wetland and wetlantl buffer areas. During the Notice of Application comment period, the City - received a comment asking why this proposed 115kV transmission line could be located within the existing.BPA corridor. Puget Sound Energy attempted to locate their fransmission corridor within the BPA right-of-way but BPA denied the request as the BPA right-of-way is fully utilized (Exhibit 16). Electrical transmission and distribution lines are non-occupied_ features and do not put additional 'demands on public serviees such as fre and police; effect traffic patterns, nor emit signifcant noise oc odors as do most perrnitted uses allowed in Residential and Light Industrial zones. ' Staff concludes that the proposed use will not have a substantively greater adverse effect on the surrounding area as the transmission corridor has existed since 1969, with the most recent easement: granted in 1981; the treeremoval is being mitigated through replanting and vegetation management, and electrical transmi5sion lines are non-occupied features which do not put demand on the transportation system or other public services. Page 5 of 12 Agenda Subject: Puget Sound Energy Christopher Substation to 51st Date: March 1, 2011 • Avenue South Transmission Line 2. The proposal is in accordance with the goals, policies and objectives of the comprehensive plan. Staff Comment The proposal is in accbrdance with the goals, policies, and objectives of Auburn's Comprehensive Plan. The Chris#opher to 51stAvenue South transmission.line corridor has been presented to the public and local agencies through a variety of ineans over the: years. This is because the project has been in PSE's long-term planning since the original land rights were obtained in the 1960s. In 1979, the Christopher Substation development project was issued a Determination of Non-Significance (DNS) and Conditional Use Permif (CUP). The SEPA Checklist that was submitted as part of the 1979 permitting process and the site plan approved undec the CUP both included future transmission lines that depart from the station. . Specifically, the transmission lines being currently proposed were shown teaving the substation to the west on the CUP exhibit. Additionally, develoPment of the corridor and initial engineering design of the corridor was started in the early 1990s and included a pre-application meeting with the Gity of Auburn and King.County (Exhibit 15). When the Growth Management Act (GMA) was established in 1990, certain counties and cities within . those certain counties were required #o develop a Comprehensive Plan; a 20-yeat vision documenf to ' guide growth and land use patterns. A copy of PSE's 1993 GMA Planning Document was provided to the City of Auburn as have subsequent updates. The map that shows proPosed transmission iines in the Auburn area from the 1993 GMA document has been previously submitted. The transmission line. corridor,isshown on Map 6.1 ofAuburn Comprehensive Plan. As noted by PSE, this location`isto the north of the actual corridor and what is depicted on Aubum's map has never been considered by - PSE. Staff acknowledges that Map 6.1 is graphic representation on/y that PSE has planned for an 115kV transmission from the Christopher Substation property eonnecting to the existing transmission line within 515t Avenue South. lt should be noted however, that this corridor has been planned for and acknowledged within Auburn's Comprehensive Plan which has had extensive public review. Comprehensive Plan Elements The following section provides the text from the Comprehensive Plan and how PSE's project is in conformance with the plan policies: Chapter 6, Goal 15 Private Utilities: To ensure safe, efficient provision of private utilities to serve all segments and activities of the community. 06jective 15:1: To allow the development of private utilities to meet the needs of the existing coinmunity and provide for its planned growth consistent with the serving utilities public service obligations. ' Policies: PU-1: Private utility companies are recognized as providers of important services necessary fo maintain current and future lifestyles. PSE constructs distribution, transmission, and transformation projects, such as the one being proposed to ensure that electricity is availab/e to all customers in a reliab/e and cost effective . manner. PU-2: Private utility providers should refer to the City's Comprehensive Plan Map for guidance regarding future land uses and intensities. Private utility facilities and systems should be consistent with the uses and densities allowed by the Comprehensive Plan and Zoning Code. The City will regularly provide this information and information on pending development proposals (both public and private) to the appropriate provider. In retum, the City expects there to be a cooperative posture towards coordinated and sensitive expansion of the infrastructure. Page 6 of 12 ~ Agenda,Subject: Puget Sound Energy Christopher Substation to 51st Date: March 1, 2011 ' Avenue South Transmission Line The proposed transmission line project has been depicted in the City's Comprehensive Plan. The project has been discussed with the City of Auburn at various times since the lafe 1970s. The City routine/y provides PSE: with notices on developi»ent proposals when Notice of Application's are published and if SEPA is, required PSE is a/so notified of those decisions. ' PU-3: Private utility companies should strive to proVide utility services to all segments of the Auburn population and areas of the community. PSE is required to proVide electrica/ services to the genera/ popu/ation within the company's service territory. Objective 15.2: To improve the safety, visuaf quality, and efficiency of private utility facilities consistent with the serving ufilities public service. Policies: PU-4: The City shall require that new private utility distribution, service and telecommunication lines be located underground within all new developments.. The City will also work with the utilit.y companies to relocate existing distribution, service and telecommunication lines underground as a pait of system upgrading orurban revitalization projects, whenever it is economically and technologically feasible. The proposed project includes the construction of 115kV transmission lines (as opposed to lower volfage distribution lines) which is not conducive to undergrounding; therefore, this policy does not app/y. ~ PU-5: Common utility tcenches should be encouraged and coordinated by both private and public providers whenever possible. The proposed project includes'the construction of aboveground 115kV transmission lines; therefore; this.policy does not app/y. When projects do inc/ude undergrounding of utilities, the - City does coordinate with PSE and other private utility providers to use common utility frenches. PU-6: To reduce visual clutter, antennas, relay mechanisms and similar structures should be located on. existing poles, structures, or buildings whenever possible_ When deemed feasible and necessary to minimize impacts on adjacent uses or views by the City, visual screening may be required. ' The proposed project entails the deve/opment of a new 115kV transmission line corridor, therefore, existing structures cannot be used: The majority of the corridor will be mainfained with" . low growing native,vegetation. Wood poles will be used in all but one location to he/p blend the system in with the surrounding enviconment. A rouYe has been se/ected thaf is as c/ose as • possible to the existing BP. A, transmission lines to he/p consolidate the visual impacts that may be associated with the project to fewer locations. PU-7: The City shall consider the environmental impacts of proposed utility facilities as a part of its environmental review process: When requested by the City; the utility provider shall furnish documentation of cucrent research results and/or provide additional information related to determining the environmerital impacts, if any, of the proposed facilities: The proposed project is subject,fo review under fhe State Environmental Policy Act. A Mitigated Determination ofNon-Significance (MDNS) wasissued on November24, 2010 wifh severa/ mitigation measures to address f/ie environmental impacts of the project Additionally, a Page,7 of 12 Agenda Subject: Puget Sound Energy Christopher Substation to 51Date: March 1, 2011 • Avenue South Transmission Line geotechnical study has been prepared for the work on the wesf slopes of the valley. Constructiorr methods have been selected that will minimize the impacts to the wetland/stream areas /ocafed adjacent to the substation. Doeumentation otfhe slopes and wef/and/sfream areas has been provided to the City. The applicant has prepared a conceptual mitigation plan for the crifical area impacts (Exhibit 19). As required by Auburn Cify Code, fina/ mitigafion p/ans uvill be required for review and approval prior to any issuance of building and/or grading permits: PU-8: The construction of facilities and provision of services by private utility providers within the City of Aubum.shall be in compliance with all of the goals and policies of this comprehensive plan. The proposed project has been included in and is in compliance with the Comprehensive P/an. PU-9: Decisions regarding private utility facilities within Auburn should consider the safe, adequafe and efficient availability of these utilities to other jurisdictions. PSE operates a comp/ex electrica/ distribution and transmission line sysfem thaf services the City of Auburn and surrounding jurisdictions. The system is operated in accordance with national safety standards. PU-10: The location of utility facilities is often dependent upon the physical requirements of the utility system. All utility facilities should be sited; designed, and buffered (through extensive screening and/or landscaping) to fit in with their surroundings fiarmoniously and safely. When . sited within or adjacent to residential areas, special attention should be given to minimizing noise, lighf and glare impacts. The 11 ¢kV transmission line will not add light or glare to the surrounding environment and noise that might emanate from the lines will be negligib/e. Additionally, the pcoposed project will connecf the Christopher Substation with the existing fransmission lines.located a/ong 51St Avenue South. The existing corridor is the most efficient and clireet route availab/e that can accommodate the new transmission lines. The corridor was se/eeted back in the mid-1960s and the property rights were obtained befween fhen and 1981. The surrounding development that is now present a/ong the corridor was constructed after PSE had obtained the corridor. A mitigafion measure identifed in the MDNS is thaf the applicant shall submit a photometric lighting p/an showing the lighting locations within the f`ransmission corridor and light directed away from the adjacent residentia/ properties. Policy EN-69: The City shall 5eek to ensure that land not developed or otherwise modified.in a manner~which wilt result in or significantly, increase the potential for slope slippage; Jandslide, subsidence or substantial soil erosion. The City's development standards shall dictate the use of Best Management Practices to minimize the potential for these problems. A geotechnical report and supplementa/ memorandum was prepared by /cic/e Creek Engineers addressing the steep s/ope impacts for the pole insfallation and free removal. Appropriate mitigation measures have been identifred in the issued MDNS. Policy EN-71: The City shall consider the impacts of new development on hazards associated with soils and subsurface drainage as a part of its environmental review process and require any appropriate mitigating measures. Page 8 of 12 Agenda Subject: Puget Sound Energy Christopher Substation to 51~ Date: March 1, 2011 • Avenue South Transmission Line The impacts to the soils and subsurface drainage were anatyzed as part of this proposal; A . supp/emental memorandum prepared by lcicle Creek Engineers addressed the additional - rainwafer being absorbed into the ground with the removal of trees within the transmission line . corridor. Appropriate mitigation measures have been identffied in the issued MDNS. EN-29: The City shall con_sider the impacts ofi new development on the quality of wetland resources as part of its environmental.review process and shall require appropriate mitigatiort and monitoring measures of important wetland areas. Such mitigation may involve conservation, enhancement or restoration or replacement ofi important wetlands, and provisions for appropriate buffering. The goal of the mitigation_ should be no nef loss of wetland functions and values. A permanent deed restriction shall be placed on any wetlands created or enhanced to ensure that #hey are preserved in perpetuity. The proposed impacts to wetlands and associated buffers within the existing transmission corridor have been addressed through the preparation of a conceptual mitigation p/an. As noted previously, a final mitigation p/an is required to be reGiewed and approved prior to any issuance of building and/or grading permits. EN-20: The City shall encourage the retention of vegetation and encourage landscaping in order to provide filtering of suspended particulates. The minimum amount of tree. removal is proposed by PSE within the transmission line comdor. The proposal is for removal of approximate/y 700 trees and approximate/y 1,190 shrubs and low growing trees will be rep/anted within the wet/andAvet/andbuffer and steep s/ope areas within fhe corridor fo mitigate the tree removal. 3.' The proposal complies with all requirements of thistitle. Staff Comment The ptoposed 115kV transmission line through the existing transmission corridor complies with the . requirements of the zoning code. The subject propertiesare zoned M-1, Light Industrial, R-1 (1 du/acre); and R=5 (5 du/acre). As required, the applicant applied for a conditional use permit. Pursuant to ACC Section 18.31.030, the height of transmission line towers located within public street rights-of-way, easements, or on. private property, and which are constructed in accordance with other regulations as required by the city are exempt of the height requirements of the specific zone. The proposed project meets the other development standards outlined in the specific zones. , 4. The proposal can.be constructed and maintained so as to be harmonious and appropriate in design, character; and appearance with the existing or intended character of the general vicinity Staff Comment The existing power line corridor'has existed since 1981 and was the only route that provided the necessary space fo accommodate the needed transmission lines, was in the general proximity of the existing utility corridors (BPA and Tacoma Water), and avoided the majority of the existing residential and commercial development thaf were present at the time the property and rights were acquired: The presence of electrical lines is part of the general infrastructure found ~in developed portions of counties and cities. Distribution of'electrical power is required for developed areas and therefore should be considered a compatible land,use. The majority of the corridor is undeveloped or minimally developed land; either open felds or forested areas. Construction of the power lines will entail the removal of existing trees along the corridor. This is necessary to provide the necessary electrical clearance from trees as prescribed in the national electric safety codes and will also help ensure reliability of the system_ Those areas that are currently vegetated will remain that way, with only the Page 9 of 12 ~ Agenda Subject: Puget Sound Energy.Ghristopher Substation to 59" Date: March 1, 2011 ' Avenue South Transmission Line incompatible trees removed and wood poles and associated conductors installed. Maintenance of _ the corridor will include periodic pedestrian oraerial inspection of the lines and selective vegetation removal if the power lines are subject to risk. Current vegetation maintenance standards for 115kV Iines allow for tree species with a maximum height of 25 feet to grow under the lines. If fast growing species, such as red alder orcottonwood seed in the corridor, they will be removed during the normal three year maintenance cycle. Substation work will include the installation of five new foundations to accommodate the new steel termination pole, bus supports; and switch stands. This work will be accomplished within the confines . , of the existing substation yard, so no expansion of this facility will be required. . As mentioned underCriteria 1, the tree removal is being mitigated through the replanfing of 1,190 shrubs and low growing trees`within the wetland/wetland buffer and steep slope areas of the transmission corridor. _ The proppsed project is impacting :the transmission corridor the minimum , necessary to accomplish the construction. 5. The proposal will 6e supported by adequate public facilities and services and will not adversely affect the public infrastructure - Staff Comment . the subjecf properties are within the City's water and sewer service areas and also Lakehaven Utility District service for the properties on West Hill. There are existing sewer and water mains along the frontage of the substation property. There are existing fire hydrants along 37,t' StreetNW. The projecf does nof,require connection to utilities. Electrical transmission and distri6ufion lines are non-occupied features and do not put additional demands on public services such as fire and police or effect traffic patterns. 6. The proposal will not cause or create a public nuisance. Staff Gomment The proposal will not cause or create a public nuisance. As mentioned under Criteria 4, PSE has-a routine maintenance program that includes periodic pedestrian or aerial inspection ofithe lines and selective Vegetation removal if the power lines are subject to risk. Pursuant to the definition of a public nuisance in ACC Section 8.12.020, the proposal does not meet any of those definitions: . 7. The proposal's impact5 can be appropriately mitigated through the application of conditions of approval, as applica6le Staff Comment The proposed 115kV transmission line through an existing transmission corridor can be appropriately, mitigated through the application' of conditions of approval and the mitigafion measures esta6lished in the issued Mitigated Determination of Non-Significance. Pursuant to Auburn City Code (ACC) Section 16.10.170 a Speciaf Exception for Public Agencies and Utilities can be applied for if the application of Chapter 16.10 would prohibit a development proposal by a public agency or public utility. The apphcant has submitted a reyuest for a Special Exception for Public Agencies and Utilities for the 415kV transniission line from the valley floor through steep slope areas (Exhibit 3). Pursuant to ACC Section 16.10.170(D) the proposal must meet the following criteria: o There is no practical altemative to the proposed development with less impact on critical areas. a The application of this chapter would unreasonable resfrict the ability to provide utility service to the public. Page 10 of 12 AgendaSubject: Puget Sound Energy Christopher Substation to 51s` Date: March 1, 2011 • Avenue South Transmission Line ~ o That the modification, if granted, will not alter the character of the neighborhood, or be detrimental to the surrounding properties in which the property is located. o The proposal attempts to protect and mitigate impacts to the critical area functions and values consistent with the other applicable regulations and standards. Comment The transmission line corridor has existed since 1969 with the most recent easement granted in 1981. This corridor has existed prior to the City's adoption of a Critical Areas Ordinance in 2005. Pursuant to ACC 16.10.100(E), alterations to Class IV Geological Hazards are prohibited. The - • existing transmission line corridor includes Class IV Geological Hazards as identified by Icicle Creek Engineers, Inc. in their geotechnical report (Exhibit 13). There is no practical alternative to the proposed development. As mentioned previously, the . transmission line corridor has been in,existence since 1981 and was the only route that provided the necessary space to accommodate the needed transmission lines, was in the general proximity of the existing utility corridors (BPA and Tacoma Water), and avoided the majority of the existing residential and commercial development that were present at the time the property and rights were acquired. The modification, if granted, will not alter the character of #he neighborhood adjacent to the steep slope area or be detrimental tothe surrounding properties. Icicle Creek Engineers, Inc. identified several mitigation measures that shall be followed during tree removal and pole installation to prevent erosion and impacts to the geologic hazard area. Those mitigation measures have also been included in the issued MDNS. Tree removal is necessary to construction the 115kV transmission lines. The tree removal is being mitigated by the replanting of 1,190 shrubs and low growing trees within the geologic hazard area and wetland/wetland buffer areas. RECOMMENDATION Based upon the application and Findings of Fact and Conclusions of the staff report, staff recommends, that the Hearing Examiner approve the Conditional Use Permit and Special Exception for Public Utilities with the following conditions of approval: . 1. The mitigation measures identified in the Mitigated Determination of Non-Signifcance issued on November 24, 2010 are hereby incorporated into the Conditional Use Permit and Special Exception for Public Utilities approval. 2. The site plan, date stamped February 8, 2011, is hereby incorporated into the Conditional Use Permit approval. Any modifications to the site plan shall be made in accordance with the provisions in Auburn City Code 18.64.035(C). 3. The Conditional Use Permit approval shall be valid for the specific use authorized on a property, , which are 115kV transmission lines and necessary improvements, subject to the revocation provisions of ACC 18.64.070. A change in use shall cause the administrative or conditional use permit to automatically expire. 4. The Conditional Use Permit shall be implemented within two years of the approval. If a building permit or occupancy permit is required for the Conditional Use Permit and has not been issued within the two-year period,'then the Conditional Use Permit shall be null and void Staff reserves fhe ►rght to supplement,the recoral of the case to respond to matters and information raised subsequent to the writing of fhis report , Page 11 of 12 Agenda Subject: Puget Sound Energy Christopher Substation to 511, Date: March 1, 2011 .

How will the proposed use have no greater adverse iim'pacf on the surrounding area than any other use generally permitted in the present zoning classification? Electrical #ransmission and distribution lines are non-occupied features and do not put additional demands on public. services (fire, police, medical, etc...), effect traffic pattems; nor emit significant noise or odors as do most permitted uses allowed in Residential and Light Industrial zones. b. Why is this Conditional Use Permit compatible with the other existing uses in the neighborhooc9? . PSE is required to provide reliable electrical power to customers within its service territory (WAC 480-100-123,..RCW 80.28.110). As growth has and continues to occur within both rural and urban settings, PSE is required to respond to the increase in electrical tlemand, by constructing new distribution, transmission, and transformafion facilities. The presenee of electrical lines is part of the general infrastructure found in developed portions of counties and cities. Distribution of electrical power is required for developed areas and therefore should be considered a compatible land use. PSE identified the need for a substation and associated transmission lines in the Aubum area in the mid'-1960s. This included the Christopher Substation site, which has been in operation since the early 1980s and the proposed transmission line corridor from the substation to 51 St Avenue South. The substation sife was purchased in 1965 and the , acquisition of property rights forthe transmission line corridor began in 1966. The corridor acquisition activities continued through 1981 when the last remaining segments were _ acquired through condemnafion. During the condemnation process, PSE had to . demonstrate to the court thaf the projecf was necessary and that it was in the pu6lic's interest. Table 1 provides a Iist of the parcels located along the corridor wherein PSE has mainfained property rights, as well as the dates of when and how the rights were acguired. This power line corridor has been in existence before many of the homes along the route had been consfructed. Much of the area has been developed around the utility line corridor. c. How will the proposed use be constructed and maintained to be harmonious and appropriate in design, character and appearance with the surrounding vicinity? The existing power line corridor.has ezisted since 1981 and was the only route that provided the necessary spaceto accommodate the needed transmission lines; was in the general proximity of the existing utility cocridors (BPA and' Tacoma Water); and ayoided the majority of the existing residential and commercial development that were present at the time the property and rights were acquired. The majority of the corridor is undeveloped or minimally developed land; either open fields or forested areas. Construction of'the power lines will entail the removal of existing trees along the corridor. This is necessary to provide the necessary electricaf clearance from trees as prescribed in the national electric safety codes and will also help ensure reliability of the system. Those areas that are currently vegefated will remain that way, with only the . . incompatible trees removed and wood poles and associated conductors installed. Maintenance of the corridor will include.periodic pedestr'ian or aerial inspection of the lines 1 of 4 PUGET SOUND ENERGY and selective vegetation removal if the power lines are.subject to risk. Current vegetation maintenance standards for 115kV lines allows for tree species with a maximum heighf of 25 feet to grow. under the lines: If fast growing species, such as red alder or cottonwood seed in the corridor, they will be ~emoved during the normal three year maintenance cycle. Subsfation work will include the installation of five new.foundations to accommodafe the new - steel te'rminafion pole, bus supports, and switch stands. This work will be accomplished within the confines of the existing subsfation yard, so no expansion of this facility will be required. d. How fis the Conditional Use Permit consistent with the Auburn Comprehensive Plan? _ The Christopher to 51st Avenue South transmission line comdor has been presented to the public and local agencies through a variety of ineans ovec the years. The Conditional -Use Permif will be consistent with the Comprehensive Plan. This is because the project has, been in PSE's long-term planning since the original land rights were obtained in the 1960s. In 1979; the ChrisfopherSubstation development project was issued a Determination of Non-Significance (DNS) and Conditional Use Permit (CUP). The SEPA Cliecklisf that was submitted as part of the 1979 permitting process and the site plan approved under the GUP ' both included future transmission lines that depart from tfie station. Specifically, fhe fransmission:lines being currently proposed were shown leaving the su6station to the west on the GUP exhibit. Additionally, development of the corridor and initial engineering design of the corridor was started in the early 1990s and included a pre-application meeting with the city of Auburn and King Gounty. A copy of PSE's 1993 GMA Planning Document was provided to the City of Auburn as have subsequent updates. The map that shows proposed transmission lines in the Auburn area from the 1993 GMA document has been previously submitted'. Comprehensive Plan Elements The following section provides the text #rom the Comprehensive Plan and how PSE's project is in conformance with the plan policies. Chapter 6, Goal 15 Private Utilities: To ensure safe, efficient provision of private utilities to serve all segments and activities of the community. Objective 15.1: To allow the development of private utilities to meet the needs of the - existing community and provide for its planned growth consistent with the serving utilities public service obligations. . Policies: PU-1: Privafe utility companies are recognized as proViders of important services . , necessary to maintain current and future lifesfyles. ' Additionally, the transmission line is shown in the current Au6um Comprehensive Plan, albeit to the nortfi of the correct location. It also should be noted that the existing BPA lines are also mapped to the north of their actual location. The actual route shown on the City's current Comprehensive Plan map has never been considered for a transmission line corridor by PSE; therefore, it is presumed that the Comprehensive Plan map has inadvertently shown the Bf?A and the proposed PSE corridor in the wrong focation. . 2of4 - PUGET SOUND EIVERGY PSE constructs distribution, transmission, and transformation projects, such as the one being proposed to ensure that electricity is available to all customers in a reliab/e and cost effective manner. PU 2: Private utilify providers should refer to the City's Comprehensive Plan Map for guidance regarding future land uses and intensities: Private utility facilities and systems should be consistent with the uses and densities allowed by the Comprehensive Plan and Zoning Code. The City will regularly provide this information and infotrnation on pending developinent proposals (both pubfic and private) to the appropriate provider. In retum, the Cify expects there to be a cooperative posture towards coordinated ancl sensitive expansion of the infrastructure. The proposed fransmission line project has b"een depicfed in the City's Comprehensive Plan: The project has been discussed with the City of Aubum at various times since #he late 1970s. ~ y PU-3: Frivate utility companies should striveto provide utility services to all segments of the Auburn population and areas of the community. . PSE is required to provide e/ectrical services to the genera/ popu/ation within the . companies service territory. . ObjectiVe 15.2: To improve fhe safety, visual quality, and efficiency ofi private.utility : facilities consistent with the serving utilities public service. Policies: PU-4: The City shall require that new private utility distribution, service and telecbmmunication lines be located underground within all new developments. The City will also work with the utility compan'ies to relocate existing distribution,, service and felecommunication lines underground as a part of system upgrading or urlian revitalization projects, whenever it is "economically and technologically feasible. The proposed project includes the construction of transmission lines (as opposed , to lower vo/tage distribution lines); therefore; this policy does not apply. . PU-5: Gommon utility trenches should be encouraged and coordinated by both private and public providers whenever possible: The proposed project includes the construction of aboveground transmission lines; therefore, this policy does not app/y. PU-6: To.reduce visual clutter, antennas, relay mechanisms and similar structures should be located on existing poles, strucfures, or buildings whenever possible. When deemed feasible and necessary to-minimize impacts on adjacent uses or views by the City; visual screening may be required. . The proposed projecf entails the development of a new transmission line corritlor, therefore, existing structures cannot be used. The majority of the ' 3 of 4 PUGET SDUND ENERGY . ~ corridor will be maintained with low growing native vegetation: Wood po/es will be used in a/l but one location to he/p blend the system in with the surrounding environment. A route has been se/ected that is as close as possible to the existing BPA transmission lines to help consolidate the visual impacts that may be associated with the project to fewer /ocations. PU-7: The City shall consider the environmental impacts of proposed utility facilities as a part of its environmental review process. When requested by the City, the utility providershall#umish documentation of current research results and/or provide additional information related to determining the environmenfal impacts, if any, of the proposed facilities. The proposed project will be subject to review under the State Environmental Policy Act. Additiona/ly; a geotechnica/ studyhas been prepared for the work on the west slopes of the va/ley. Construction methods have been selected that will minimize the impacts to the wetland/sfream areas /ocated adjacent to the substation. Documentation of the slopes and wet/and/stream areas has been provided to the city. , PU-8:. The construction of facilities and provision of services by private utility providers within the Gity of Aubum shall be in cornpliance with.all of the goals and policies of this comprehensive plan. The proposed project has been included in and is in compliance with the Comprehensive Plan. PU=9: Decisions regarding privafe utility facilities within Auburn should consider the safe, adequate anci efficient availability of these utilities to other jurisdictions. PSE operates a complex electrical distribution and transmission line system that services;the city of Auburn and surrounding jurisdictions. The system is operated in accordance with national safety standards. PU-10: The location of utility facilities is often dependent upon the physical requirements of the utility system. All utility facilities should be sited, designed, and buffered (through extensive screening and/or landscaping) to fit in with their surroundings harrnoniously and safely. When sited within or adjacent to residential areas, special attention should be given to minimizing noise, light and glare impacts. The transmission line will not add light or glare to the surrounding environment and noise the miglit emanate from the lines will be negligib/e. Additiona/ly, the proposed project will connect the Christopher Substation with the existing transmission lines located along 515t Avenue South. The existing comdor is the most effieient and direct route available that can accommodate the new transmission lines. The corridor was se/ected back in #he mid-1960s and fhe property rights were obtained between then and 9981. The surrounding development that is now present along the coccidor was constructed after PSE had obtained the corridor.- 4of4 - City of Auburn Special Exception for Public Agencies and Utilities IV PUGETSDUND ENERGY SEP09-0022: Christopher Substation fo 51't Avenue South Transmission Line Project Obyect6ves and Description To better serve the electcical demand needs in the area; Puget Sound Energy, Inc (PSE), has determined that a new fransmission line corridor is necessary to connecttfie existing transmission line located along 51 st Avenue South to the existing Christopher Substation, located at 1002 37"' Street NW, Aubum, WA. The corridor will be developed to accommodate three firansmission lines, which will be constructed in phases in the future. PSE has an , established, buf undeveloped utility.corridor that is either owned'in fee or established by recorded easement. This corridor was established approximately thirty years ago in anticipation of this project. The first of three transmission lines to be construction will exit out of#he substation in the northwest comer and travel to a single wood pole, then turn to the west for a.bout 180 feet to a three-pole wood structure. Then #he line will tum south-southwest for about 550 feet to another three-pole wood structure, with the line tuming to the.southwest over SR-167 to a single steel pole (-98 feet tall) located approximately200 feet east of the West Valley Highway. The line ; spans the West Valley Highway via a 1,000-foot span to a two-pole wood structure and continwes on wood pole structures in the same general direction for about 3,300 feet, where the line turns due west and follows South 304t' Street for another2,700 feet to the terminus of.k e ; project at 51st Avenue South. The future fransmission lines and fiber optic line will essentay . follow the same alignment. DeveloPment of the new -100-foot wide 115 kV transmission &e rn !T~ r. . corridor will be completed during the installation of the frst line; therefore, facilitating the c~ construction of the additional lines in the future. N Substation work will include the installation of fve new foundations fo accommodate the nemr rn~f steel termination pole, bus supports, and switch stands. This work will be accomplished w@in ? 1 the confines of the existing substation yard, so no expansion of this facilifiy will be requiredas . part of this project. Therefore, the subsfafion work is not discussed further in this documept, ~ As it relates to critical areas; the proposed project will require the installation of three transmission line structures in.the wetland area located along the west side of the Christopher _ Substation. As the transmission line continues to the west, Mill Greek, an unnamed creek, and fourwetlands will be spanned, but no additional strucfures will be plaeed within the unnamed ereek, wetlands orassociated buffers. In addition to the creeks and wetlands, a steep slope is located west of the 1Nest Valley Highway. PSE plans to clear the trees within the corridor on the slope fo facilitate construction and operation of the transmission line. Creeks, wetlands, and steep slopes as tlesignated critical areas and are subject to specia( ceview bythe city of Auburn. The review cciteria for a Special Ezception for Public Agencies and Utilities as presented in the Auburri Municipal Code Chapter 16.10;170(D) are provided following the critical area descriptions below. Critical Area Descripfaons Details of each ofi the critical areas located: along the project are provided in the Wetland Delineation and Stream, Assessment (ENSR 2008). A summary for each area'is provided below to assist with the evaluating the review criteria. Mill Creek -'Mill Creek enters the Christopher Substation site approximately midway along the southem boundary. after flowing beneath 29t' Street NW. The stream splits into two branches almost , 1 of 5 , • • PUGET SOUND ENERGY immediately upon entering fhe site. The west branch flows west just inside the southem site boundary, then makes a 90 degree tum and flows north just inside the western site boundary. When it reaches the northern site boundary; the west branch flows through a culvert beneath 37'" Street NW and off of the site. The east branch ofi Mill Creek flows north from the southem site boundary through the center of the site until it reaches the boundary of a forested wetland area. At fhis point, the stream:channeF becomes indistinguisliable as it expands into a large area of shallow open wafer: The iocation of:Mill Creek as mapped in the field corresponds well with the location mapped by the City of Aubum. According to WDFW, the portion of Mill Creek - within the Chrisfopher Substation site contains fall Chinook salmon (Oncorhyncus tshawytscha), wintersteelhead (O. mykiss), and coho salmon (O. kisufch). Therefore, according toAubum CAO regulations, #his stream is classified as a Class II stream, which has a 75-foot buffer. Unnamed Creek The unnamed creek labeled as "KC Stream° in King Counfy G1S layers flows roughly to the north through the project corridor, approximately midway along the transmission line corridor. The portion of the stream channel within the study area, as field-checked by ENSR using GPS, matches well with the location of fhe stream in the GIS tlata layer provided by King County. The stream varies from 1 to 4 feet in width and from 1 to 6 inches in depth within the corridor, and flow velocity in moderate. The area on both sides of the stream is a wetland, and in some areas surface watet can be seen flowing directly into the stream. Habifat complexity of the stream is mini►'nal. The stream . exhibits almost no sinuosity, braiding, riffles and pools, or retention structures. No fish were obserVed in the unnamed creek, wtiich is probably too shallow to support fish and according to WDFW, the creek is not utilized 6y fish. However, several types of macroinvertebrates were found on the stream bed, and algae were observed growing on larger sediments. According to the guidance in the Aubum CAO, this stream is classified as Class III Stream, which has a 25= foot buffer. Wetlands Wetland.A is a small, depressional palustrine emergent (PEM) wetland, approximately 0.025 acres (1,100 square feet) in size. It is located in an open, disturbed area nearthe western end of the project corridor. Dominant species include orchard grass, creeping buttercup (Ranunculus repens), and common velvetgrass (Holcus lanafus): This wetland occurs at a site, of possitrle fill deposition, as evidenced by the presence of a wooden stake deep in the soil pit. The wetland has been classifed as Category IV, which have maximum buffers of 30 feef. It has , . moderate water quality functions,• but low hydrologic and habitat functions. Wetland B is a small PEM wetland, approximately 0.027 acres (1,190 square feet) in size. It is a narrow ditch, approximately 2 feet wide, with banks about 1 foot high located east of Wetland A. The ditch is oriented roughly north-south and appears to serve as a channel for surface water from upslope areas during wef periods. Dominant plant species include creeping buttercup, bentgrass, orchacd grass; and stinging nettle. This wetland is located just east of a moist wooded area. It has been classified as Category IV. It has moderate water qualiiy functions, but low hydrologic and habitat functions. Wetland C is a large PEM/Palustrine Forested (PFO)/Palustrine Scrub/Shrub (PSS)'wetland , associated with the channel of the unnamed creek that extends beyond the surVey atea to the north and south. Approximately 0:5 acres of this wetland are locafed within the study area, but the entire wetland is much larger, extending north and soufh from the study area as it follows 2of5 . PUGFT SOtIND ENERGY the stream channel: ENSR delineated a single wetland centered about the stream channeL The ernergent;portion is dominated by bentgrass, orchard grass, tall fescue (Schedonorus phoenix), and meadow buttercup. in the wetter portions, common rush becomes more prevalent. The forested portion of the wetland is a riparian area along the"stream channel. The predorninant tree species is red alder, with a Himalayan blackberry understory. ~The scrub-shrub portion of the wetland is dominated by Himalayan blackberry. Wetland C has been classified as a Category II wetland, primarily because it has a high potential, and the opportunity, to reduce flooding and erosion and improve water quality: , Wetland D is a small PEM/PSS/PFO wetland, approximately 0.3 acres (14,300 square feet) in size and is located near the fop of #he west hill side, wesf of.the substation. This wetland was delineated in 2007, although with slightly different boundaries. The emergenf portion is dominated by orchard grass, common rush, and meadow'_buttercup, with small areas of reed canarygrass. The dominant tree in the forested portion is red alder, and understory dominants include Himalayan blackberry and Indian plum (Oem/eria cerasiformis). Herbaceous dominants in the forested portion include meadow buttercup and large-leaved avens (Geum macrophyllum). The scrub-shrub portion consists almost entirely of Himalayan blackberry. Wetland. D has been classified as a Category III wetland. lt has low hydrologic functions and moderate water quality and habitaf functions. Wetland E is a single large PEM/PSS/RFO riverine wetland that occupies that majority of the Christopher Substation site. Portions of the site were filled during the original development of the substation. Deposition of fill has altered the hydrology, in some portions of the site enough that isolated areas no longer function as wetlands. These sites have been mapped as upland areas. V1letland E is approximately 59 acres (2,567,000 square feet) in size (with upland inclusions subtracted). The PEM component is predominant, at! approximately 46.6 acres (2,028,000 square feet), followed 6y PFO (8.4 acres; 365,000 square feet) and PSS (4.0 acres; 173,000 square feet). Because #he open water component is very small and difficult to separate out, it has been lumped with the more dominanf components accordingly. Within the PEM component, reed canarygrass is nearly ubiquitous. This species forms a dense coverage of most of the wetland, and dominates many of#he upland inclu"sions as well. In more deeply , inundated'areas, cattail is the dominant species. In the forested wetland portions, red alder and willows are prevalent along streams, and red alder and balsarn poplar are prevalent in other areas. Where the forest is multi-layered (i.e., non-riparian areas behind the substation), red- osier dogwood is an important understory component, and creeping buttercup is predominant in the herbaceous layer. The PSS component occurs primarily along portions of the creek and drainage ditches. Dominant species are Douglas spirea and red-osier dogwood, with some Himalayan blackberry where the wetland is transitioning to upland. This wetland has been rated as a Category Il wetland. It has moderate water quality functions, and high hydrologic and habitat funcfions. Additionally, the wetland may be subjecf to increased protection'requirementS because.Mill Creek is utilized by listed salmonid species, and because the wetland contains a priority species, the great blue heron (Ardea herodias). ' Review Criteria 1. Thete is no other practical alternative to the proposed development with less impact on critical areas. 3 of 5 • • PUGET SOUlVL3 ENERGY . New electrical transmission lines are necessary fo accommodate growing electrical demand and to help facilitate system reliability in the project area. As the Christopher Substation is surrounded by wetland, all future expansion and addition of new transmission lines will have to cross wetland5 and could cross over Mill Creek. The power line corridor has been established since 1981 and was assessed as the on(y route that provided the necessary space to accommodate the needed transmission lines; was in the general proximity of the existing utility corridors (BPA and Tacoma Water); and avoided the majority of the existing . residential and commercial development that were present at the time the property and rights were acquired. Wetland located along the corridor cannot be avoided as they route is situated befinreen the existing BPA transrnission line corridor and existing.development. There are no other known routes that could be developed that would have less impact to wetlands. Additionalfy, the fransmission line structures will be constructed outside of the wetlands and their associated buffers located along the corridor. Electrical system requirements dictate that the new lines connect to the Ghristopher . Substation and travel west towards 51 St Avenue South. All routes would traverse the west hill out of the valleyand therefore cross through steep slope areas. Ecisting developments limit the options of where the comdor could be constructed. 2. The application of the CriticaF Areas Chapter would unreasonably restrict the ability to _ provide utility services to the public. In order to meet the increasing electricaL loads in Aubum and surcounding areas, the improvements to the substation and the addition of new#ransmission lines needs fo be consfructed. Without the substation improvements and construction of the new transmission lines, the reliability of the electricaf system in the area could become compromised and elecfrical load demands not met. PSE is required to provide reliable elecfrical power to custorners.within its service tecritory (VVAC 480-100-123, RCW 80.28.110). As growth has and `continues to occur within both rural and urban settings, PSE is required to respond to fhe increase in electrical demand by constructing new distribution, transmission, and fransformation facilities. The presence of electrical lines is part of the general infrastructure found in developed portions of.counties and cities. 3. The proposal does not pose an unreasonable threat to the public health, safety, or welfare on or off the development proposal site. The proposed project will not pose a threat to the health or safety of the public: Construction of the project will improve health and safety by providing a reliable source of power to the public. The new substation equipment would be placed within the fence line of the existing utility yard. This yard is a secure facility that is monitored on a regular'basis. . The newtransmission lines will be placed on tall wood and stee( poles out of range from the general public. Poles instafled on the steep slope area will 6e done so in accordance with fhe recommendations made by the geotechnical engineers (Icicle Creek 2008). 4of5 ^ - PUGET SDUNI3 ENERGY 4. The proposal attempts to protect and mitigate impacts to the critical area functions and values consistent with other applicable "regulations and standards. The,construction and operation of the new substation equipment will not result in permanent impacts to critical aceas or their buffers as the work will take place within the developed and fenced area of_the existing substation. The construction of the transmission lines will involve placing poles along the steep slope that composes the west hili side of the valley. PSE has had the hill side evaluated by geotechnical experts and will follow their recommendations so that irnpacts will be minimized. The installation of pole5 in Wetland E located on the Substation property as this cannot be avoided: HoweVer, every effort was made to design the transmission line project so that structures wete not placed in the four other wetlands or their buffers. Modfication to the ~ vegetation'located in the other four wetlands and their associated buffers is expectetl; however, excepf for`the actual poles; no loss of wetland will occur. Creeks will be spanned bythe transmission fines, but impacts are expected to be negligible., PSE will work with the City to address such impacts and ensure that the appropriate wetland mitigation is perFormed. This will be documented in a mitigation report and plan that will be submitted to the City: . , 5of5 W ❑ U m a 2 P > N ~W ~ o 0 00 Z ~ (n z W O W O ~ ❑ J } Q ~o z r a~ OW~a U o W ~ z rw w`❑ NJ o ~ wm >U W ~ W Q I m o v 0 / z~ Q w U r man lrWa ~ ~ O Q m N" ° v1 i m i d 2 W O h O n n ~ N ° D 2 I a= x x❑ WrJ U Z j rci ~ 0 a~ NS W r r w ~n a a s 3 ~ ~ z ~ a ~ W 2 O ~ W o0 2U C7 U ~ a ra f ~ ° ~ - Z ZwZar° ~ ~m~ wrr Z ~i ~ ~ w° a ~ W ~ ~ W U ~ y ryroy ~ a~~ air. o Q a~ x- V7 0 7 Z 7 Z] N a ..W D; 3~ h Q c~ c~ u w ~W~r O Q U ~ Z Z Z Z j Z ~ w❑ W ZUUZ m0 Q p 0 O 3 3 U a aw K aZ W CC 3 D 3 0 3 ~ rw Jaln~ ~d ~ W~ h I c7 ❑ rn n e w W wOK^ O ~ h ~ i w ~ CCw~ ° o 0 o m 7 u1W00 KW U W W w z rr Q ❑ wzmo dr h s z o a 2 ~ ~'~z W ~ u W u K =OOW da m h~ z~ ° x W> a aaaaaa ~ i i i P d rUa~ ao - ~ ~ J~^ a° ° ~ N m ~ o z ~ ~ w Z a ~ m m~ umi rc w ~ z^~ ° O w W N ~ N N N N Z d ~o N N N N N N rn M rn M x a N°° 2 a o O a~ w ott~ i ~ _ ~ N ~ a N O ~ ~ N O WOV N N r ° m wtt LL ~ UJW x N o U J~ J02 0 0 I ~ Q w ~o U in a~nw a° P ~ dog Qi >~ti m - o Q OAR wF ~ ^zo N WhJ zw = ~a O O D❑ ~ Q ~ U W ow U do °z ~ 'z ~ a- U U U U U U ❑ ~ln ~ Z ° z W W W a❑ ❑ 2 Z Z Z Z Z h= a _ ~ a a a a a a .zoo V Q O uwi v U ~?N ~~rrw W ~ ~ N z xxxxxx --p,~ ~ " a J J J J J J " n [ W Q 3 O Q ~ 0~ 2 2 2 2 2 2 O O N If1 'p D 0 ~ 2 (Wj O m ~ O P N N [ [ Q=?

Fact.based upon impacts identified in the environmental checklist and the "Final Staff Evaluation of the Environmental Ghecklist.No. SEP09-0022", and Conclusions of Law based upon the Auburn Comprehensive Plan, and other Municipaf policies, plans, rules and regulations designated as a basis for the exercise of substantive authority under the Washington State Environmental Policy Act Rules pursuant to R.C.W. 43.21C.060. Findings of Fact: 1. The .proposed project action involves 15'. parcels. The applicant proposes to construct a new 115kV transmission tine corridor from the existing Christopher Substation site to 51s' Avenue South. The project will be constructed on property owned by Puget Sound Energy or within existing easements. ' The transmission corridor ranges from 100-200 feet in width. The transmission corridor will eventually confain two additional 145kV transmission lines that will be constructed at a future date with the entire corridor being'prepared now for that fuCure installation: The initial line will be ins#alled along the northem most extent of-the corridor with the future lines being installed south of the first line. 2. The corridor comprising the initial proposed 115kV transmission line and finro future 115kV transmission line will begin at the western portion of the exisfing substation yard and continue north for 150 feet #o a single wood pole and then continue west for about 180 feet to a three-pole wood structure. The corridor will nexfi turn south/southwest for about 550 feet to another three-pole wood structure, after which the will continue southwest of SR -167 to a single steel pole (approximately 98 feet tall) located approximately 200 feet east of the West, Valley_Highway. The corridor is proposed to span West Va11ey. Highway via a 1,000 foot span to a two-pole wood structure and continue on wood pole structures in.the same general direction for about 3;300 feet, before turning due west and . following 3outh.300 Street for another.2,700 feet to the project terminus at 51d Avenue South. The future 115kV transmission lines and inch diameter fiber,optic line will occuc in the same corridor alignment. The fiber optic line is to control the electrical system and is used only by Puget Sound Energy. . Page 1 of 7 ~~~URN ~ MORE THAN YOU IMAGINED . , MITIGATED DETERMINATION OF NON-SIGNIFICANCE SEP09-0022 (Continued) Substation work will inciude the installation of five new foundations to:accommodate the new steel termination pole, bus suppoits, and switch stands. This work will be accomplished within the current configuration of f the existing subsfation yard, so no expansion ofthis facility is required. 3. Total anticipated excavation work related to new wood pole installations will consisf of,approximately 60 cubic yards and 50 cubic .yards for the excavation for the steel pole foundation. Excavation for the new foundation within the existing substatiorr yard will include ' the removal and ezport of approximately 20 yards. Total grading will be approximately 130 cubic yards: 4. The proposed use is consistent with the Light Industrial zoning designation specified in Chapter 18.32 of the Auburn City Code. The proposed transmission corridor does extend into residentially zoned property. Pursuant to Section 18.32.040.C of the Aubum Gify. Code, utility facilities and substations, may be permitted within residential zones subject to conditional use permit approval. 5. Pursuanf,to 18.64.020(B) the City of Aubum Hearing Examiner is authorized to conduct a duly . ~ noticed public hearing and render a final decision on a conditional use permit appl'ication. The ` Hearing Examiner's decision is appealable to the Superior Court of the applicable county . government. 6. The substafion property is within the City's Water and Sanitary sewer service area. A portion of the transmission line corridor is also within the Lakehaven Utility' District for water and sanitary sewer. 7. Requirements of ACC Chapter ,15.74 Land Clearing, ACC Chapter 15.68, and ACC 16.10 are applicable to the site. . Compliance with these referenced chapters of the Au6um City Code will be evaluated as part of the City's land use or environmental or engineering or building permit approval process in which a decision to approve, approve with conditions ordeny will be made, as applica6le. 8. No sta#e or federal candidate threatened or endangered plant species have been identifed on the site. This was assessed using State Department of Natural Resources Priority Habitat Data. 9. The City shall seek to ensure thaf land not developed or otherwise modifed in a manner which wiU result in or signifcantly increase the potential for slope slippage, landslide; subsidence or subsfantial soil erosion. The City's development standards shall dictate the use of Best Management Practices, , to minimize the potential for these problems (Policy EN-69, Auburn Gomprehensive Flan'(ACP)). 10. The Ciry will seek to ensure thaf the guality of water leaving the City. isof equivalentguality to the water entering. This will be accomplished by emphasizing prevention of pollufion to 5urface and . ' ground waters through education programs and implementation and enforcement of Best Management Practices.

The Gity shall consider the impacts ofnew development on water quality as part of its environmental review process and require any appropriate mitigating measures: Impacts on fish resources shall be. a priority concem in such reviews: (EN-13, ACP) 15. The City shall require the use of Best Management Practices to enhance and protect water quality as dictated by the City's Design and Consfruction Standards and the Washington State Department of Ecology's Stormwater Management Manual for the Puget Spund Basin. In all new development, approved water quality treatment measures that are applicable and represent the best available science or technology shall be required prior to discharging storm waters into the City storm drainage system or into environmentally sensitive areas (e.g. wetlands, rivers, and groundwater.) (Policy EN- 14, ACP) 16. The City recognizes the important 6iological and hydrological roles that wetlands play in providing plant_and animal habitat, protecting water quality, reducing the need for man-made flood and storm drainage systems, maintaining water quality, and in providing recreational, open space, educational and cultural opportunities. The City will consider these roles and functions in all new development and will also pursue opportunities to enhance the existing wetland system when these multiple benefits can be achieved. (Policy EN-27, ACP) ' 17. The City recognizes that wetlands provide varying degrees of biological and.hydrological functions , and values #o the community depending on the size, complexity and location of the individual system, and tfiat the overall degree ofifunctions and values should be considered when reviewing proposals which impact wetlands. In a similar manner, the levels-of protection afforded to a wetland.shall be consistent with its existing function and values. The City shall continue to promote policies and practices of enhancing the wetlands that are hydraulically connected to the river systems to improve fish resources and aquatic habitaf. (Policy EN-28, ACP) 18. The ,City shall consider the impacts of, new development on the quality of wetland resources as part of its environmental review process and shall require appropriate mitigation and monitoring measures of important wetland areas. Such mifigation may involve conservation, enhancement or restoration' or replaeement of important wetlands, and provisions for appropriafe buffering. The goal of the mitigation should be no net loss of wetland functions and values. A permanenf deed restriction shall be placed on any wetlands created or enhanced to ensure that they are preserved in perpefuity. (Policy EN-29, ACP) 19. Where possible, streams and river banks should be kept in: a natural condition, and degraded streambanks should be enhanced or restored: (Policy EN-6, ACP) 20. The City shall encourage the retenfion of vegetation and encourage landscaping in order to provide, filtering of suspended particulates (Policy EN-20, ACP). 21. The City shall seek to protecfiany unique, rare, or endangered species of plants and animals found within the City by preventing the indiscriminate and unnecessary removal of trees and groundcover, by promoting the design and developmenfi of landscaped areas which provide food and cover for wildlife; and by protecting and enhancing the quality of aquatichabitat (Policy EN-23, ACP). 22. The City shall consider the impacts of new development on the quality of land; known or suspected _ fish and wildlife habitats (Map 9.2) and vegetative resources as a part of its environmental reviewprocess and require any appropriate mitigating measures. Such mitigation may involve the retention - of significant habitats and the u5e of native.landscape vegetation. (Policy EN-24, ACP) Page 3 ofi 7 'I MITIGATED DETERMINATION OF.

Webands which are associated with a river or stream, or provide significant plant and animal habitat . opportunities are recognized by the City as the most important wetland systems, and shall receive the highest degres of protection and mitigation through conservation; enhancement or relocation measures: Wetlands which are limited in size, are isolated from major.hydrologicaL.systems or provide limited hydrological or plant and animal habitat opportunifiesmay be considered by the City for development arid displacement in conjunction with appropriafe mitigation. (Policy EN-30, ACP) 25. Private utility companies are recognized as providers of important services necessary to maintain current and future lifesty,les. (I'olicy. PU-1, ACP) 26. The location of utility facilities is often dependent upon the physical requirements of the utility system. All utility faeilities shou_Id be sited, designed, and 6uffeted (through extensive screening and/or land_scaping) to ft in with their surroundings harrrioniously and safely. When site within or adjacent:to residential ateas, special attention should be given to minimizing noise, light, and glare impacts. 27. The proposed project entails significant tree removal within the 100=200 wide foot transmission line corridor to provide clearance #or the lines. Approximately 700 trees will be removed from the transmission line corridor. The trees to be cleared mainly consist of second=growth western red cedars, red alders, black cottonwoods, Douglas-firs, maples, western hemlocks; and pines. The goal of the tree removal in the transmission line corridor is to remove large, problem tree species and develop lower growth-from plant communities composed of low growing sFrrubs and small-scale trees. The maximum mature height of plants in the 115kV fransmission line right-of-,way is 25 feet. A total,of 1,194 trees and shrubs will be replanted. within the corridor; 268 within the: landslide and erosion hazard area and 926'within the wetland and wetland 6uffer areas. 28. Pursuant to ACC Chapter 15.74. and City of Aubum Design Standards, a temporary erosion and sediment control plan is required to.be approved and implemented on the site prior to and during site development. Potential. 'significant- adverse environmental impacts associafed witfi erosion and, sedimentation,from this development is adequately mitigated through compliance with this regulation , and rnitigation measures outlined in this determination. , 29. The applicant has also filed an application for a special'exception for public agencies and utilities from the City's critical area regulations pursuant to Auburn City Code 16.10.170 for construction within a Class IV Landslide Area and Geologic Hazard Area. 30. The Federal Aviation Administration issued a"Determination ofi No Hazard to Air Navigation" on December 16, 2008 fof the proposed 115kV transmission line corridor. The applicant shall notifq the : FAA th'rough Form 7460-2, Notice of Actual Gonstruction of Alteration, within 5 dayS after tlie construction reaches its greatest height. 31. Tfie "Final Staff Evaluation for Environmental Checklist No. SEP09-0022" is fiereby incorporated by - reference: CONCLUSIONS OF LAW: Staff has concluded that a MDNS may be issued. This is based upon the environmental checklist and its attachments, and the "Final Staff Evaluation of the Environmental ChecklisY'. The MDNS is supported by Plans and tegulations formally adopted by the City for-the exercise of su6stantive authority under SEPA. Tfie MDNS also takes note of.the extent to which many local, State and Federal regulations and permit requirements will govern the:project to mitigate its potential impacts, in accordance with WAC 197-117158 and RCW 43.21 C.240. The following are City adopted pol'icies, which support the MDNS: Page 4 of 7 MITIGATED DETERMINATION OF NON-SIGNIFICANCE SEP09-0022 (Continued) 1. Tfie applicant's report: Critical Area Reaort Geotechnical Engineerin4 Services Right-or-Way , Clearing - Tree Removal West Ghristopher Transmission Line Riqht-of-Wav, prepared by Icicle Creek Engineers, Inc. dated May 30, 2008; identifies that a portion of the transmission line cortidor crosses several thousand feet of Class IV Landslide and Erosion Hazard Areas. The entire corridor, approximately 100-200 feet wide, will be cleared of 700 trees to facilitate construction and to accommodate the future transmission lines. The conclusions of the report state, "that the removal of trees may be completed without 'adverse impacts to the stability of the sfeep slopes or erosion, ~ provided that recommendations in this report are implemented.°= AU recommendations outlined in the geotechnical report shall be followed. 2. Icicle Creek Engineers, Inc. prepared a supplemental technical memorandum dated March 18, 2010 related to rainfall interception of mature trees. Preservation of the° topsoil and vegetation base is essential. The topsoil layer along with vegetation base, if preserved as recommended, should protect the sife from erosion and slow runoff similar to that of tha existing: condition during the winter months. : The supplemental technical memorandum also addressed runoff.. The memorandum stated fhat based on the ground cover types before and after tree removal, the runoff coefficient would still fall within the range of "ForesY" which.ranges from 0.05 to 0.25. The recommendations presented in the ' May.30, 2008 shall be implemented. 3. The applicant's report: Christopher Substation to 51"t Avenue South Wetland Delineation and Stream Assessment prepared by AECOM; dated August 2008 identifies that the site and transmission . corridor contains streams and wetlands within the project limits. The proposed action does not include filling ocelirninating.wetlands; however, the project includes construction within and proximate to wetlands, Mill Creek, Tributary 0053, and associated buffers. More specifically, construction will include tree removal within wetland and wetland buffer areas and excavating approximately 110 cubic yards of dirt/200 square foot impact to Wetland E for the wood pole installation (two 3-pole and one . single pole structure) at the Christopher Substation. property: Installation' of the poles will create a - temporary impact and will not result in a reduction of material within Wetland E. Access to the'pole locations will be made during:the dry season using timber mats or equivalent where necessary to , minim'ize soil and vegetation impacts. 4. To protect site wetlands and compensate for converting portioos of forested components of Wetlands C, D, and E AECOM prepared a wetland impact assessment-and conceptual m'itigation plan report dated April 2010, supplemental memorandum dated May. 20; 2010, and a concepfual planting plan dated May 27, 2010. As mentioned under Finding No. 10, the wetland impacts are primarily tree removal only with a small impact to existing, emergent .wetland, 200 square feet at the substation property and 28 square feet of'buffer at Wetland C. The proposed conceptual mitiga6on plan calls for a 4:1 shrub/low growing tree replacement ratio for the. forested, emergent, and scrub/shrub wetland (Wetland C) and a 6:1 shrub/low growing tree replacement ratio for the forested wetland (Wetland E). . The bufferreplacement rafio is 1:1 (Wetlands A, B, C, and D). 5. To ensure the success of wetland mitigation construction and steep slope mitigation construction; the City will review and approve final mitigation plans, require annual monitoring inspections, and the preparation of annual monitoring reports for the length of the monitoring period. 6. To help ensure the long-term `preservation of the wetland mitigation area and to discourage the ' ' uncontrolled intrusion of humans info the mitigation areas, a mechanism such as a recorded agreement will be required in accordance with ACC 16.10. 7. Based on the current FEMA maps; the site contains 100-year floodplain associated with Mill Creek. The filled and graveled yard of fhe sutistation is higher than the surrounding area and surveyed at 47.75 feet median sea level (MDNS SEP06-0032). The proposed transmission line corridor and pole installation do not create additional impervious surfaces that will impact the 100-year floodplain of Milf Creek.

Other Approvals: The checklist application identifies a number of approvals that may be needed for the project. In addition, a right-of-way use permit`will be required for crossing V11est Valley Highway.from the City of Auburn and a right-of-way use permit from WSDOT for crossing $R-167. B. Environmental Elements: 1. Earth: Soils along most of the project corridor are mapped as Alderwood gravelly sandy loams, with, slopes ranging from 0 to 30 percent. These are moderately well* drained upland soils that'formed in glacial deposits under conifers. In the steep area at the easf end of the project corridor, soils are mapped as very steep Alderwood and "Kitsap soils. Soils at the subsfation side are mapped primarily' as Oridia; Renton, and Norma series soils, witti a small area of Puget series soils (USDA Soils Gonservation Service 1973). The Ordia and Renton series are somewhat poorly drained silt loams tfiat formed in alluvium in Final Staff Evaluation for Environmental Ghecklist SEP09-0022 - Page 3 . ~ river valleys. The Norma soils are sandy loams that occur in basins and along stream bottoms. The Puget series are poorly drained silty clay loams that formed in small, depressions of river Valleys. The slopes of all these series are less than 2 percent. 2. Air: Short-term impacts on air quality could occur during "site preparation operations: - Construction activity, including the hauling necessary for the importation' of fill material will contribute to short-term increases in local suspended particulafe levels.:. These impacts will be controlled through watering the site as necessary, street cleaning, temporary erosion control and other measures in accordance with the City's Design and Construction Sfandards manuaL 3. Water: A. Surface: The sife ofthe electrical switching yard contains wetlands and the western edge of the substation yard property contains Mill Creek, a Class 2 stream that was realigned for the original construction of the electrical substation. Through tfie transmission 'corridor, there are four wetlands and Tributary 0053 that`will be impacted through tree removal. No filling of these four wetlands is proposed. The applicant's report: Christopher Substation to 51St Avenue_._South. Wetland Delineatibn and Stream Assessment prepared ' by AECOM, dated August 2008 identifes that fhe site and transmission, corridor contains streams and: wetlands within the project limits. The proposed action does not include filling or eliminating weflands; howeVer, the project includes construction within and proximate to wetlands, Mill Creek, Tributary 0053, and associated buffers. More specifically, construction will include tree removal within wetland and wetland buffer areas and excavating approximately 110 cubia yards of dirtI200 square foot impact to Wetland E for the wood pole installation (two 3-pole and one single pole structure) at the Christopher Substation property. Installation of the poles will create a temporary impact and will not result in-a reduction of.material within Wetland E.. Access to the pole locations wilf be made during the dry season using timber mats or equivalent where necessary to minimize -soil. and vegetation impacts. ' To protect site wetlands and compensate for converting portions of forested components of Wetlands C, D, and E AECOM prepared a wetland impact assessment and conceptual mitigation plan report dated April 2010,.supplemental rnemorandum dated May 20, 2010, and a conceptual planting plan dated May 27, 2010. As mentioned under Finding. No. 10, the wetland impacts are primarily tree removal only with a small impact.to existing emergent wetland, 200 square feet at the su6stafion property and 28.square feet of buffer at,Wetland C. The proposed conceptual mitigafion.plan calls for a 4:1 shru6/low growing tree replacement ratio for the fo'rested, emergent, and sCrub/shrub wetland (Wetland C) and a 6:1 shrub/low growing tree . replacement ratio for the forested wetland (Wetland E). The buffer replacement ratio is 1:1 (V1letlands A, B, C, and D). A final mitigation and monitoring shall be submitted for review and approval prior to any issuance of.grading permits. . B. Groundwater: The proposed project includes construction within a Class IV geologic hazard area. The applicant has applied for a special exception for utilities in order to construct the project. The geotechnical report and supplemental memorandum Finat Staff Evaluafion for Environmental Checklist SEP09-0022 = Page 4 " . : prepared by Icicle Creek Engineers discusses groundwater impacts because of the proposed tree removal within the transmission comdor. The geotechnical engineer _ recommendswill be followed during tree removal'to minimize the impacts to groundwater and erosion issues. Preservation of the topsoil and vegefation base is essential. The topsoil Iayer along with vegetation base, if preserved as'recommended, should protect the site from erosion and slow runoff similar to that of the existing _ condition during the winter montFis. The supplemental technical memorandum also addressed runoff. The merriorandum stafed that tiased on the ground cover types before and after tree temoval, the runoff coefficient would still fall within the range of "Forest' which ranges from 0.05 to 0.25. The recommendations presented in the May 30, 2008 shaU be implemented. C. Runoff/Stormwater: The proposed construction will result in a minimal increase in impervious surFace: A ' small increase may be attributable to the electrical equipment and foundation installed . within the substation yard. To minimize impacts erosion and runoff from construction - activities, the project is proposed to adhere#o the PSE standard guidelines for temporary erosion and sedimentation control procedures (Critieal Areas Report Christopher Substation Distribution- Feeders Proiect.

(Policy EN-141 ACP) The City recognizes the important biological and hydrological roles that wetlands play in providing plant and animal habitat, protecting water quality, reducing the need for man- made flood and storm drainage systems, maintaining water.quality, and in.provicling . recreational, open space, educational and cultural opportunities. The City will consider these roles and functions in all new development and will also pursue opportunities to enhance the existing wetland system when these multiple benefits can'be achieved. (Policy EN-27, ACP) The City recognizes that wetlands provide varying degrees of, biological and hydrological functions and values to the community depending on the size, complexity and location of the individual system, and that the overall degree of functions and values should be considered when reviewing proposals which impact wetlands. In a similarmanner, the levels of protection afforded to a wetland shall be.cons'istent with its existing function and values.

The proposed site because of its proximity to Mill Creek, wetlands and due to its . considerable size. currently provides some limited habitat for upland and wetland dependent species. Mill Creek and it backwater are classified as critical.habitat because of the support listed fish species. Wetland E because of its large size and diversity_,of habitats is classifed as secondary wiltllife`habitat under the city's critical a-rea regulations. Wildlife use of the wetland habitats adjacent to the project would primarily be limited to songbirds and small mammals. WaterFowl would use the open water area of wetland E year-around and similar port'ions of the other weflands when they are inundated in the winter and spring. Raptors may forage over open habitats in. the area, possibly perch, and - nest in the larger trees on the west and south parts of the subsfation site. Amphibians are . likely to use all the wetland habitats as breeding habitat in.the spring, and adjacent uplands habitats at other times of the year. Under the current proposal, the wildlife habitat currently provided by the existing site will be impacted through site preparafion and construction. Increases in,noise generation, displacing of food sources could result from the project during construction and disrupt the existing niche for the habifants of tliis urban wildlife community. Proposed wetland mitigation will restore and primari ly improve, habitat functions for local wildlife.

Give a brief, complete description of your proposal, including the proposed, uses and the size of the project and site. There are several questions latec in ` tFthis checklist that ask.you to describe certain aspects of your proposal. 'You - need not repeat #hose answers on this page. ' To better serve the electrical demand needs. in the area, Puget Sound Energy, Inc. (PSE), has determined that a new transmission line is necessary to connect the . existing transmission line located along 51 st Avenue South to the. existing _ Christopher Substation; located at 1002 37th Street NW, Aubum; WA. To , accommodate the new transmission line, PSE has an established, buf undeveloped utility corridor that is either owned in fee or established by recorded easement... This corridor was established approximately thirty years ago in anticipation of this project: ' Development of the existing approximately 100 to 200-foot wide 1.15 kV transmission , line comdor will start from the westem portion of the existing substation yard, continue north for 150 feet to a single wood pole, then tum to the west for abouf 180 feet to a-three-pole wood structure. Then the line will tum south-southwest for about 550 feet to another three-pole wood structure, with the line tuming to the southwest. over-SR-167 to a single sfeel pole (-98 feet tall) locafed approximately 200 feef east of the West Valley Highway. The line spans the West Valley Highway via a 1,000- foot span to a two-pofe wood structure and continues on wood pole structures in the same general direction for about 3,300 feet, where the line tums due west and ENVIRONMENTAL CHECKLIST Page 2 of 22 ' Environmental Checklist (continued) TO BE COMPLETED BY APPLICANT follows South 30e. Street for another 2,700 feet to the terminus of the project at 51 St Ayenue South. The future transmission lines and fiber optic line will essentially follow the same alignment. Substation work will include the installation of five newfoundations to accommodate the new.sfeel termination pole, bus supports, and switch stands. This work will be accomplished within the confines of the existing substation yard, so no ezpansion of this facility will be required. Construction methodswill include various BMPs. that will contain potential surface- and storrnwater runoff on site within the construction area. As shown on the, . accompanying drawings, water encountered within the:construction area will be contained on.sife and #reated a§ necessary. . . , . , 12.

If a proposal , would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal clescription, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you.are_not.required to duplicate.maps or detailed plans submitted with any permit applications related to this checklist_ The substation site is located within the City of Auburn in the NW of Section 1; in T21 N, R4E; Willamette Meridian. and Baseline: The existing substation is located at 1002 37th Street NW; Parcel Number 1580600050, east of State Highway 167 and south of 37th Street NW. The transmission line corridor is situated in the SWand SE'/< of Section 2 and the NW'/4 and SW'/< of Section 1, T 21 N; R4E, Further details are provided above in Section 11 and as shown on the accompanying drawings. , . _ B. ENVIRONIVIENTAL ELEMENTS: 1. Earth: . A. General description of the site (circle one):, Flat, rolling, hill steep slopes mountainous, other. ' The substation site is essentially_flat; however,;the transmission line corridor traverses the west side of the Green River/Auburn Valley. B. What.is.the steepest slope on the site, (approximate percent slope)? The substation is located at approximately:50, feet above mean sea IeveL The transmission line route traverses the westem hilt side of the valley to the project; terminus. at the intersection of $outh 304"' Sfreet anc! 51't Avenue South, which is at about 500 feet above mean sea level. The corridor crosses the study area in a rising traverse of an east-facing hillside overlooking the ,Green. River valley. From West Valley. Highway. North at about Elevation,70 feet, the comdor traverses slopes (steep, slopes) that. generally exceed 40 percent grade,to intersect with the nearly level upland area at about Elevation 300 #eet. The steep slope areas are typically even-surFaced with no stream valleys or.swales observed along the ROW:. Locally; less steep areas exist along the corridor, in particular a narrow: bench at about Elevation• 115 feet ENVIRONMENTAL CHECKLIST Page 3 of22 Environmental Checklist (continued) TO BE COMPLETED BY APPLICANT near Wesf Valley Highway North. A second, much smaller and moderately sloping bench occurs,at about Elevation 175 feet near the midpoint of the corridor in the study area. The, existing BPA and other utility easements south. of the comdor traverse similar terrain, though the slopes are somewhat less steep (less thah 40 percent grade) in these areas. , C. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? Ifyou know the classification of agricultural soils, specify them and note any primefarmland. Based on the observations made by Icicle Creek Engineers of surficial soil exposures within the study area, it appeared fhat the native soils consist of glacially overridden sand with variable amounts of silt and g-ravel (pre-Fraser ° sediments), consistent with regional mapping by the USGS. Weathered soils mantle the ground surface in a layer up to 5 feet and consist of silty"sand'with variable amounfs of gravel and roots; generally consistenf with regional mapping by the SCS: _ The soils present on the PSE substation parcel, according fo tfie NRCS (SCS) Web Soil Survey;'are primarily (-85 percent) composed of Noima sandy loam `(No) and Oridia silt loam (Os). Puget silfy clay loam (Pu), Renton silf loam (Re); ` and Urban land (Ur) make up the balance of fhe soils mapped`on the parcel. The transmission line corridor is primarily composed (-60%) of Alderwood gravely sandy loam (Ag6, C, and D), with some Alderwood.and Kifsap soils (AkF) - (-20%), Norma sandy loam (No) (-~,15%);, and :Renton silt loam (Re) (-5%). D. Are there sucface indications or history of unstable soils in the immediate - vicinity? If so, describe. . Icicle Creek Engineers did not observe. surface evidence of slope instability within - or adjacent to the corridor, including the BPA and other utility easements located to the south. 81ope instability is typically manifested by uneven topography,,bare - soils scarps, groups of leaning or toppled trees. Additionally, evidence of erosion - within the corridoc was not observed. However, local areas of erosion (gullying) . were observed in the BPA and other utility easements to the south. Some of this erosion had been partially mitigated by placement of quarry spalls. . Other areas of erosion appeared to result from the lack of proper erosion control measures I and infcequenf maintenance. None ofthese erosion occurrences observed appeared to be causing significant damage. I E. Describe the purpose, type, and approximate quantities of`any filling or: grading proposed.. indicate source of filL Tlie excavation activities associated with the installation of the seventeen wood : pole structure locations #or the first line (comprising finro 3=pole; finro 2-pole, and ° twelve 1-pole structures) and one steel pole location will be limited. Typically, wood poles are installed by augering a hole (-2 to -3 feet in diameter and -8 to -12 feet deep). The pole is placed in the hole and the annulus is backfilled with 9cavel. The soil sPoils are either sPread around tHe base of the pole'with a mulch covering or hauled off site to an approved disposal site. The steel pole foundation will be constructed by excavating the subsurfaee foundation area, installing a rebar cage and then adding concrete with the ENVIRONMENTAL CHECKLIST Page 4 of22 Environmental Checklist (continued) TO BE COMPLETED BY APPLICANT appropnate pole.anchor-.points: After the foundation has cured, the base of the pole is attached with the additional height sections added. The excavation for the steel pole foundation will be approximately 7 feet, in diameter and about 33 feet deep. Total anticipated excavation work related to wood pole installation will entail approximately 60 yd3. The excavation for the steel pole foundation will entail around 50 yd3. Excavation for the new foundation within the existing substation yard will include the removal and export of approximately 20 yd3. Excavation associated with the fufure electrical lines is expected to be similar to that of the first line. F. Could erosion occur as a result of clearing,'construction, or use? If'so, generally, describe. During construction, temporary measures (besf management practices [BMPs]) • will be implemented to reduce the potential for soil `erosion. However; significant erosion is yery unlikely at the substation, as the site is`essentially~'flat and site disturbances will be kept to.a minimum. _ . ; The transmission line comdor crosses several thousand feet of Class IV Landslide and Erosion Hazard A'reas. The entire corridor (approximately 100- to - 200-feet wide) will be cleared of trees, which have a mature height of greater than 25-feet, ta,facilitate consfruction and to accommodate future transmission lines. According to Icicle Creek Engineers, the removal of trees may be completed without adverse impacts to the sfability;of,the'steep slopes or erosion, provided that appropriate mitigations measures are implemented.. The native soils (pre-Fraser sediments) are not particularly susceptible to landsliding or - adverse erosion. However, the surficial weathered soils :that mantle the ground surFace are#ypically not as dense as the native-soils and can be susceptible to shallow landsliding and erosion, if not mitigated. . , , . . Based on,the observations made by lcicle Creek Engineers of the BPA and other utility, easements located to tlie south of the corridor, similar land clearing"(tree . cutting) has occurred with no significant impacts with.regard to slope stability and erosion. G. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? There. will not, be a.change in the quantity of impervious surface as a result of this project. . ' . H. Proposed measures to reduce or control erosion, or other impacts to the earth.. Appropriate BMPs will be used to reduce and/or minimize the potential for erosion and_ sedimentation. Disturbed areas will be revegetated where possible . to provide long-term stabilization to the project area. - Mitigation measures for Landslide and Erosion Hazard Areas are directly related. Often, a landslide problem begins as an erosion problem. Focusing on mitigating erosion potential has the benefit of reducing landslide potential. For this reason, the recommendations developed for this project are direcCed primarily at reducing erosion potential with respect to tree cutting in the corridor. Icicle Creek ENVIRONMENTAL CHECKUST Page 5 of 22 Environmental Checkiist (continued) TO BE COMPLETED BY APPLICANT Engineers recommend the following tree removal practices to reduce the potential for post-tree removal landslides and erosion. • Cut tree stumps and root mats should be left in place. • Brush and non-hazardous trees should not be cut to the extent this is practical. • Tree removal in the Class IV Landslide Hazard Areas should be completed by hand carrying in small pieces or suspension cable systems, such that dragging of the cut tree across the natural ground surFace is reduced. • Small limbs and tree trunks may be left on the steep slope areas provided they are cut into pieces (no more than 10-feet long) and scattered on the ground surface. However, the larger trees will generate a considerable amount of woody debris and most of this material should be removed as °scattering" of this material may not be practical. • Excessive disturbance to the ground surface, such as rutting caused by tree removal, should be repaired using hand tools and covered with an appropriate ground cover (e.g., straw mulch or other appropriate erosion control products). • Tree cutting and the installation of erosion control measures should be observed by a representative from our firm to evaluate the effectiveness of erosion control measures installed and to provide additional recommendations, as needed. • The ROW on the steep slope will be replanted with suitabte tree seedlings, within one year following the tree removal. • Temporary road access and/or transmission line structures (such as monopoles) should be further evaluated for geotechnical recommendations depending on the location of these features (not known at this time) to reduce impacts to slope stability and erosion. 2. Air: A. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if know. Fugitive air emissions, such as dust and vehicle exhaust, will occur as a result of construction activities. These activities will be minor and temporary in nature. B. Are there any off-site sources of emissions or odors that may affect your proposal? If so, generally describe. No off-site sources of emissions or odors will affect the proposed project. ENVIRONMENTAL CHECKLIST Page 6 of 22 Environmental Checklist (continued) TO BE COMPLETED BY APPLICANT ~ C. Proposed measures to reduce or control emissions or othec impacts to air, if any: Dust impacts will be generally limited to the construction area. Should they become necessary, appropriate BMPs will be used to control'dust. Off-si#e impacts could potentially include dust along the.roadways. 3. Water:. - A. SurFace: : 1) Is there any surface water body on or in the immediate vicinity of the site;(including year round and seasonal streams, saltwater, lakes, ponds, wetlands): _If yes, describe type and provide names. If appropriate, state what stream or river it flows into. As shown in the accompanying documentation, wetlands are located on the substation property and along the transmission line corridor. Mill Creek is also present along the westem edge of the substation yard property. Mill Creek, which is a Class 2 stream, flows to the north. into the Green River. The wetlandareas located on the substation property discharge to the north and then west along 37t' $treet NW uia drainage ditches to Mill Creek. - Streams: ~ Mill Creek enters the Chrisfopher Substation site approximately rnidway along the southern boundary after flowing beneath 29th Street NW. The stream splits into finro branches almost immediately upon entering the site: ' The west branch flows west just inside the southem, site boundary, then makes a 90 degree tum and flows north just inside the westem site bounda 'ry. . WFien the creek reaches the, northem site- boundary; the west 6ranch flows through a culvert beneath 37t' Street NVN and off of #he site to the north. The east . branch of Mill_ Creek flows north from the southem site boundary through the center of the site until it reaches the boundary of a forested wetland area. At this point; the stream channel' becomes, indistinguisfiable~as it expands into a large area of shallow open water. The location of Mill Creek as mapped in the fietd corresponds well with the location mapped by"the City of Auburn. According to WDFW, the-portion of Mill Creek within the Christopher Substation site contains fall Chinook salmon; winfer.steelhead; and coho salmon. Therefore,. according to Aubum CA0 regulations, this stream is classified as a Class. II stream. West Branch - The west.tiranch of MiII.Creek is the_largest stream in the study area and provides the tiighest guality aquatic habitat. The substrate comprising the stream bed is a fine, m`uddy silt with sedimenfi particles less than 1 millimeter in diameter. The sediment;,ranges in color from a light brown to a dark green, but there is almost no variability in particlesize or . texture along the stream. In areas with deep, slow water, organic matter such as decomposing leaves and twigs has collected on the stream bottom. The wetted width of the channel is variable along its length, ranging from 4 to 22 feet at the time.of.the survey, with an average of about 15 feet. Bank width varies from 4 to 32 feet and averages about 20 feet. The rate of flow of " the stream is slow to moderate, with barely pecceptible flow in deep pool ENVIRONMENTAL CHECKLIST Page 7 of 22 Environmental Checklist (continued) TO BE COMPLETED BYAPPLICANT areas and faster flow with surface ripples in a few areas. The channel profile is generally rounded; although in some areas the deepest part of the channel lies to one side of the. channel. Water depth in the deepest part of the . channel is typically between 4 and 6 feet: _ Dominant vegetation species surrounding the stream include reed canarygrass, red alder, and willows, with cattail, Himalayan blackberry, and birch found less commonly. Surrounding vegetation height varies from 2 feet to 40 feet, and the degree of stream shading ranges from none to nearly co"mplete shading. Retention structureswithin the stream.are generally uncommon along the - west branch, with infrequent, small.diameter woody debris and overhanging branches from live trees in the stceam channel. There is little habitat complexity along mosf of the stream as a result of the previous rerouting and channelization of the stream. . Riffles and pools ace uncommon, and there is little braiding of the channel. In the portion ofi the stream near the southwest comer of the site; however, there are several pieces of large-diameter woody debris that have'created deep pools and-cover habitat for fish and other`aquatic species. This" area likely represents the best available fish habitat within the-study area. No fish or other aquatic animal species were observed in the stream. Although fish are reported to occur in this area;.the fine; homogenous substrate:of this ' portion of the stream provides poor,conditions formost aquatic macroinvertebrates and fish. - - East Branch - The east branch of MiII.Creek flows north through emergent . . wetland habitaf composed almost entirely of reed canarygrass. Along nearly the entire east.branch, the substra#e is a light brown, fne silt with particles less than 1 mm in diameter. A few larger cobbles arefound at the extreme southem end of the.east.branch. Bankwidth varies from 10 to 30 feet, and wetted widtFi varies from 8 to 20 feet. Flow,velocity is extremely slow along the errtire stream course. Water depth, in the deepest part of the channel ranges from 2.feet to over 4 feet but is believed to be less than 6 feet throughout the stream. Reed canarygrass: is the dominant vegetation surrounding the stream, but Douglas spirea, Himalayan blackberry, and black hawthorn are also present along portions of the stream banks. Vegetation height' is generally less than 3 feet.. Stream shading ranges from almost none to partial shade. With the exception of `some slight channel meandering and in-stream vegetation, the east branch exhibits almost no habitat complexity. No fish or other aquatic animal species were observed in the stream. Although fish are reported to occur in this area, the fne; 'hbmogeneous - sedimentmakes it unlikely that many macroinvertebrates are found'in this portion of the sfream channeL Other Streams. Drainage ditches were identified within the Christopher _ Substation site running along the northem, eastem, and southem boundaries of the site. These ditches appear to 6e hydrologically connected', although the direction of flow is unclear in some areas,-and they are apparently ENVIRONMENTAL CHECKLIST Page 8 of 22 Environmental Checklist (continued) TO BE COMPLETED BY APPLICANT manmade. A ditch along the northem boundary of the site flows west into Mill Creek at the point where it flows beneath 37t' Street NW. This north drainage ditch is 4 to 6 feet wide and 1 to 2 feet deep, and it appears to receive wetland runoff from the north end of the site. The drainage ditch along the eastem site boundary is more diverse, with open water cattail marshes at its northem and southem ends and a thicket of Himalayan blackberry and Douglas spirea in the middle. There is no perceptible direction of flow along this drainage ditch. The southem drainage ditch flows west along the site boundary until it meets the junction of the east and west branches of Mill Creek. This ditch is 2 to 4 feet wide and 2 feet deep, and is heavily clogged with aquatic vegetation resembling algae. None of the drainage ditches identified in the site provide suitable habitat for fish, nor are they mapped in King County GIS data. An additional drainage ditch was identffied along the west boundary of the Christopher Substation site, west of Mill Creek, but lies just beyond the site's western property line on the far side of a wire fence. This channel was not mapped in the field. Wetlands: During field surveys, five wetlands (identified as wetlands A through E in the prepared wetland delineation report [ENSR/AECOM 2008] were delineated along the transmission line corridor (wetlands A through D) and at the substation property (VNetland E). Wetland A is a small, depressional palustrine emergent (PEM) wetland, approximately 0.025 acres (1,100 square feet) in size. It is located in an open, disturbed area near the westem end of the transmission line comdor. Dominant species include orchard grass, creeping buttercup, and common velvetgrass. This wetland occurs at a site of possible fill deposition, as evidencsd by the presence of a wooden stake deep in the soil pit. The wetland has been classified as Category IV. It has moderate water quality functions, but low hydrologic and habitat functions. Wetland B is a small PEM wetland, approximately 0.027 acres (1,190 square feet) in size. It is a narrow ditch, approximately 2 feet wide, with banks about 1 foot high. The ditch is oriented roughly north-south and appears to serve as a channel for surFace water from upslope areas during wet periods. Dominant plant species include creeping buttercup, bentgrass, orchard grass, and stinging nettle. This wetland is located just east of a moist wooded area. It has been classffied as Category IV. It has moderate water quality functions, but low hydrologic and habitat functions. Wetland C is a large PEM/palustrine forested (PFO)/palustrine scrub-shrub - (PSS) wetland associated with a stream channel that extends beyond the survey area to the north and south. Approximately 0.5 acres of this wetland are located within the project corridor, but the entire wetland is much larger, extending north and south from the study area as it follows the stream channel. The emergent portion is dominated by bentgrass, orchard grass, tall fescue, and meadow buttercup. In the wetter portions, common rush becomes more prevalent. The forested portion of the wetland is a riparian ENVIRONMENTAL CHECKLIST Page 9 of 22 Environmentai Checklist (continued) . TO BE COMPLETED BY APPLICANT area along the stream channel. The predominant tree species is red alder, with a Himalayan blackberry understory. The scrub=shrub portion of the wetland is dominated by Himalayan blackberry. Wetland C has been classified as a Category 11 wetland, primarily because it has a high potential, and the opportunity; to reduce flooding and erosion and improve water , quality. Wetland D is a small PEM/PSS/PFO wetland, approzimately 0.3 acres (14,300 square feet) in size. The emergent portion is dominated by orchard grass, common rush; aod meadow buttercup, with small areas of reed = canarygrass. :The.dominant tree in the forested portion is red alder, and understory dominants include Himalayan blackberry and Indian plum. Herbaceous dominants in the forested portion include meadow buttercup and large-leaved avens. The scrub-shrub portion consists almost.entirely" ofi . Himalayan blackberry. Wetland D has been classified as a Category III wetland. It has low'hydrologic functions and moderate wafer.quality and habitat functions. - Wetland E is a single large PEM/PSS/PFO riverine wetland that occupies thaf majority of the Christopher Substation site. It is approximately 59 acres (2,567,000 square feet) in size (with upland inclusions subtracted). The PEM component is, predominant, at.approximately 46.6 acres (2,028,000 square ' ` feet), followed by PFO (8.4 acres; 365,000 square feet), and PSS (4:0 acres; 173,000 square feet). Because the :POW component is verysmall and difficult to separate out, it has been lumped with the more dominant components accordingly. Within the PEM componenf, reed canarygrass is nearly-ubiquitous. This species forms, a dense coverage of most of the • wetland; and dominates many of the upland inclusions as well.. In-more deeply, inundated areas, cattail is the dominant species. In the,foresfed . wetland portions, red alder and willows are prevalent along streams, and red alder and. balsam poplar are prevalent in other areas. Where the forest is multi-layered (i.e.; non-riparian.areas behind the substation), red-osier dogwood is an important understory-eomponent, and.creeping buttercup_is predominant in the herbaceous layer: The PSS component occurs primarily along portions of the creek and drainage ditches. Dominant species are Douglas spirea and red-osier dogwood, with some Himalayart blackberry where the wefland is transitioning to upland. This wetland has been rated as a Category II wetland. It has moderate water quality #unctions, and high hydrologic and habitat functions: -Additionally, :the wetland may be subject to increased protection requirements because Mill Creek is utilized by listed salmonid species, and because the wetland contains a priority species, the great blue heron. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. The proposed.project has been designed to minimize'the.amount of work. necessary in and adjacent to the above described waters. Ttiree pole locations (0/1, 0/2, and 0/3) will be located in emergent wetland. Timber mats will be. used to access these locations in order to minimize potential impacts. ENVIRONMENTAL CHECKLIST Page 10 of 22 Environmental Checklist (continued) TO BE COMPLETED BY APPLICANT All other pole strucfures will be installed outside of waterbodies and their associated buffers. Some vegetation removal. may be required around the waterbodies and their buffers that are situated along the transmission line corridor: This removal will be minimized to the extenf possible and be primarily limited to non-ground disturbing activities. , 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected: :Indicate the source of fill material. The excavation activitie"s in th'e wetland.area will result from the installation of the three wood pole transmission line structure locations (two 3-pole and one single-pole strucEure)- located on the ChristopFier Substation property. Installation of the poles will create only temporary minor impacts and will not result in a net increase oc reduction of material within the wetland. In addition, sixteen down guy anchors will be installed within the wetland area. Triple helix anchors will be used and are essentially tumed directly in.to the soil without excavation. Approximately 18 yd3 of materials w(ill used excavated for installation of the wood poles on the substation property outside of the fenced area. Access to the pole locations will be made during the dry season using timber mats (or equivalent) where necessary to minimize soil and vegetation impacts: Soil excavated for the poles will be removed and' hauled off site. 4)" Will the proposal require surface waterwithdrawals or diversions? Give general description, purpose, and approximate quantities if known. There will be no surFace water withdrawals.or diversions associated `with the proposed project. Groundwater or storm.water could accumulate. within the pole excavations.: If this occurs, the water will be pumped out of the holes to a flat upland vegefated area, to a temporary storage/settling tanks, or to.tank trucks. 5) Does the proposal lie within a 100-year floodplain?'If so, note location on the site plan. . The entire substation parcel is located within a 100-year floodplain. This has been noted on the plans. The transmission line corridor,is not located within the 100-year floodplain. ' 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated `volume of discharge. No; PSE will implement BMPs to contain potential surface or storm water on- site. If excess water is encountered during construction, then this water will . be collected on-site and treated if necessary.. ENVIRONMENTAL CHECKLIST Page 11 of 22 Environmental Checklist (continued) TO BE COMPLETED BY APPUCANT B. Ground: 1) Will ground water be withdrawn, or wi,ll water be discharged to ground water? Give general description, purpose, and approximate quantities if known. _ No ground water will be withdrawn or water discharged to ground water as a result of this project: 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for_example; domestic.sewage; industrial, containing any toxic chemicals; ag'ricultural; etc.). Describe , the general size of the system, the number of such systems, thenumber of houses to be served (if applicable), or the number of animals or humans the system(s) is (are) expected to serve: ' Not applicable. . C. Water Runoff (including storm water): 1) Describe the.source of runoff (including storm water) and method of collection and disposal, if any (include quantities,;if:known), Where will this water flow? Will-this water flow into other waters? If so, describe: Runoff from the proposed project will be associated only. with stormwater that could originafe during construction activities. Work. withih the: substation~will be relatively minor; therefore, containment of stormwater wilF be managed on site using appropriate BMPs. Work within the substation wetland area will be minimized.by using timber mats,.limiting work to the dry season, and using appropriate BMPs. Actual work within the wetland area is minimal andincludes the installation of seven wood power poles. Runoff. from the wetland pole locations will be 'minimal as the area is flat and land disturtiance will - likely be less than. 50 ft2: The remainder of the'transmission li'ne corridor.will . ' be cleared of large trees forthe length of#he route. Stormwater will be . = managed using the appropriate runoff controls specified in the Icicle:Creek Engineers Geofeehnical study and on the design plans. 2) Could waste materials enter ground or surface waters? If so, generally describe. Waste materials will not enter the ground or surface waters. D. Proposed measures to reduce or control surface, ground, and runoff water . impacts, if any: , Construction activities will be conducted during the dry season, thereby minimizing the potential for stormwater run off. Additionally, vegetation removal and soil disturbance will be minimized to the extent possible. Areas thaf are .disturbed will be controlled using appropriate BMPs. 4. Plants: A. Check or circle types of vegetation found on the site: ~ deciduous tree: alder, maple, aspen, other. - ~ evergreen tree: fir, cedar, pine, other. ~ shrubs.

Z wet soil plants: cattail, buttercup, bullrush, skunk cabbage, other. ❑ water plants: water lily, eelgrass, milfoil, other. ❑ other types of vegetation. B. What kind and amount of vegetation will be removed or altered? Vegetation removal at the substation site will be minimal and primarily limited to a few trees located near the northwest comer of the substation. Removal of the trees is necessary as they will be in conflict with the new transmission lines, as well as future lines coming out of the station and traveling towards the comdor. The transmission line will be above ground, thereby minimizing ground disturbances. Transmission line corridor vegetation clearing will include the removal and/or topping of up to 700 trees, primarily composed of Douglas fir, big-leaf maple, red alder, Westem red cedar, Westem Hemlock, black cottonwood, cherry, and Sitka spruce. A parcel by parcel summary of the estimated quantity and types of trees that will likely be removed, trimmed, or topped is provided in the table below.

List threatened or endangered species known to be on or near the site: No known threatened and endangered plant species are expected to be in the immediate project area. D. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: To the extent possible, existing understory vegetation will be maintained along the transmission line corridor. Tree topping or removal near sensitive areas will be closely monitored and minimized. In those areas where tree removal is ' necessary, appropriate shrub species may be planted to provide soil stability and provide vegetation diversity. Replacement vegetation will be planted on the steep slope and in wetlands/streams and their associated buffers. Mitigation for vegetation removal is provided in the Mitigation Report. 5. Animals: A. Circle any birds and animals which have been observed on or near the site or are kno to on or, near Wte: , ongbir(see below) Birds: haw hero eagle Mamma s. dee ear elk, beaverFish: bass, salmo trou heRing, , ther: Along the proposed project corridor, the following bird species were observed or heard: American crow (Corvus brachyrhynchos), American robin (Turdus migratorius), Steller's jay (Cyanocitta stellen), northem flicker (Colaptes aurafus), dark-eyed junco (Junco hyemalis), black-capped chickadee (Poecile atricapilla), ENVIRONMENTAL CHECKLIST Page 14 of 22 Environmental Checklist (continued) TO BE COMPLETED BY APPUCANT and pileated woodpecker (Dryocopus pileatus). Most of these birds were associated with patches of forested habitat within,and near the corridor. _Additionally, an active red=tailed hawk (Buteo jamaicensis) nest was observed, at the east.of the project corridor,;near the West Valley Highway. The only mammal encountered was a rabbit or hare of unknown species. Out of species encounfered, only pileated woodpecker is a priority species, with breeding areas , considered priority areas. Biologists clid not confirm the presence of breeding areas in the project corridor; it is more likely that suitable breeding habitat would be located in the forested - area to the north of the project corridor. -At the Christopher Substation site, biologists noted coyote scat in numerous: places along grassy roads/trails witliin the site: Bird and:waferfowl species observed along and near MiII Creek include Americanbittem (Botaurus lentiginosus), black-and-white warbler. (Mniotilta varia), hooded merganser (Lophodytes cucuUatus), mallard (Anas platyrhynchos), marsh wren (Cistothorus palustris), and song sparrow (Melospiza melodia)._ . Near the drainage ditch along the site's eastem boundary, biologists saw American crows, hooded mergansers, red-winged blackbirds (Agelaius phoeniceus), and brown-headed cowbirds (Molothrus ate►). Bird species observed in forested areas in the north end of the site include downy woodpecker (Picoides pubescens), black-capped chickadee, - American robin, and song sparrow. Marsh wren was common at the site, and was heard in many locations within emergent wetland areas dominated by reed canarygcass. Two great blue herons and a northem flicker were seen flying over the central portion of the site. An active redtailed hawk nest was observed ~hear , the southwest corner of the substation. Of the species observed at the site, great blue heron is considered a priority species by WDFVN. Breeding areas are considered priority habitats. No great blue heron nests were observed in forested areas on the site; so use of this area as breeding 'habitat cannot be confirmed. The,observed birds could possibly be part of a large breeding colony. of herons roughly 2 miles,south of the site. B. List any threatened or endangered species known to be on or near the site. The nearest:documented bald eagle nest is locafed a little more than 2 miles to the northeast, adjacent to Lake,Fenwick (WDFW 2006).: A documented great blue heron colony is located approximately 0:6 m'ile east of the substation, just north of 37th Avenue NW along a minor tributary of the Green River: Several salmonid species are known to use Mill Creek, including fall Chinook, fall chum, coho salmon, and winter steelhead. The Puget Sound Evolutionarily Significanf Unit (ESU) of Chinook salmon is listed as threatened the National . Oceanic.and Atmospheric.Adm,inistration (IVOAA Fisheries);-while the winter steelhead is. proposed for listing as threatened. MiIICreek~is also designated . critical habitat for Puget Sound Chinook salmon, It is I_ikely that the reach,of. Mill Creek in the project vicinity is used primarily as migration and rearing habitat by resident species. C. ls the site part of a migration route? If so, explain. The proposed project will be constructed within the existing fenced switchyard . and across the wetland located to the north and east: Salmonids are suspected ' of using'the drainage ditches and channels that'pass through ttie wetland. Some salmonids could use this corridor as a migration route. Water fowl species are known to use the wetland aceas during the wet season. ENVIRONMENTAL CHECKLIST _ Page 15 of 22 Environmental Ghecklist (continued) , TO BE COAAPLETED BY APPLICANT D. Proposed rneasures to preserve or enhance wildlife, if any: - As part of PSE's transmission pole design standard, the distance between- conductors and grounding apparatus of power lines, will have a minimum spacing of 60-inches. This design sfandard will eliminate the potential electrocution risk to raptors. No other measures are being proposed. 6. Energy and Natural Resources: A. What kinds of energy.(electric, natural gas, oil, wood stoye, solar).will be. . used to meet the completed project's energy.needs? Describe whether it will be used.for heating, manufacturing, etc: . In order to meet current and future electrical demand in this portion of PSE's service territory, PSE has determined that this project is necessary, .The proposed projecf is part of the electrical distribution utility system and will not require the use of other utilities to operate. B. Would your project affect the: potential use of solar energy by adjacent properties? If so, generally describe. The new,transmission lines will not impact the potential use of solar power generation by adjacent properties. C. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any: " - . Not applicable, 7. Environmental Health: A. Are there any enviconmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or. hazardous waste that could ` occur as a result of this proposal? If so, describe. Tlie site is occupied with an existing electricalswitch yard and, associated utility corcidor. The proposed project includes the updating of equipmenf and improvements to tfie electrical transmission/distribution system. The project will not create'any known environmental health hazards. PSE's substations, transmission; and distribution facilities are designed, constructed, and operafed in acco.rdance with all applicable federal, state, and local regulations and safety codes. Elec#rical transmission lines, distribution lines, and substations create electric and magnetic fields (EMF). EMFs also exisf in nature and around all types of electrical devices and appliances. Electromagnetic fields are produced by the presence of electric charges (voltage); the movement of those charges (current) produces magnetic felds. The electrical and magneticfields around electrical appliances and utility facilities are referred to as extremely low frequency EMF. They have a significantly lower frequency (60 cycles per second, or Hz), then_ radio broadcast waves (0.5 to 100 million cycles per second) or electromagnetic energy from sunshine (1,000 trillion cycles per second). Extremely.low frequency EMF- does not have sufficienf energy to break molecular bonds or damage DNA. PSE relies on the independent scientific research community#or information regatding EMF and potential health effects. The consensus ofthe scientific ENVIRONMENTAL CHECKLIST Page 16 of 22 Environmental Checklist (continued) TO BE COMPLETED BY APPLICANT community is descnbed in a number of reports that have been released by respected independent scientific groups representing a variety of disciplines including physics, epidemiology, and cellular biology. A review of these sources has found no causal relationship between exposure to extremely low frequency EMF associated with 60 Hz electrical facilities and adverse effects to human health. Currently the EPA or any other health agency of the state or federal government does not regulate electric and magnetic fields. This is consistent with the consensus of the scientific community that there is no basis from which to conclude that exposures to EMF cause adverse health effects. 1) Describe special emergency services that might be required: No special emergency services are required at the substation or along the transmission line corridor. 2) Proposed measures to reduce or control environmental health hazards, if any: No hazards will result from the proposed project; therefore, no measures to reduce such hazards have been proposed. B. Noise: 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, other)? Noise will not adversely affect the proposed project. 2) What types and levels of noise would be created by or associated with the project on a short-term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. Noise will be generated during construction primarily by the operation of heavy equipment. Construction activities will likely occur Monday through Saturday, between the hours of 7:00 a.m. and 6:00 p.m. and meet the requirements of the Aubum Municipal Code chapter 8.28.010(8). There will be no appreciable noise emanating from the facility at the completion of this project. 3) Proposed measures to reduce or control noise impact, if any: Construction will meet the requirements of the City of Auburn's Noise regulations. 8. Land and Shoreline Use: A. What is the current use of the site and adjacent properties? The site is an electrical transmission switch yard and a utility/recreational corridor. The property to the west is occupied by State Highway 167; to the south by vacant land; and to the north and east, by commercialrndustrial developments. ENVIRONMENTAL CHECKLIST Page 17 of 22 Environmental Checklist (continued) TO BE :COMPLETED BY APPLICANT B. Has the site been used for agriculture? If so, describe: It is unknown 'rf the substation property has been historically used for agriculture. . Much of#he Auburn/Kent Valley has been used foragricultural purposes in the past. Based on location and topography, if is unlikely that'the-transmission line comdor has been used for agriculture; however, Christmas trees have been , know to be grown along the'transmission line'route. - C. Describe any structuces on the site: The substation site contains transmission poles and various elecfrical appurtenances, including an electrical switch yard. . . D. Will any strucfures be.demolished? If so, what? No occupied structures will be demolished as a result of the proposed project. A dilapidated bam is located along the transmission line comdor that will likely be demolished. E. What is the current zoning classification of the site? The substation parcel is zoned Light Industrial District (M1), per the city of Aubum. The parcels located along the transmission line 'corridoc are zoned;. Single-Family Residential (RS/LHRS and R11LHR1),'and Public Use (P1/LHP1). F. What is the current comprehensive plan designation of the site? The substation' parcel is within a Light Industrial land use area per the city of Auburn Compreliensive Plan.

Indicate whether high, middle, or low-income housing. No units will be eliminated as a result of the proposed project. C. Proposed measures to reduce or control housing impacts, if any: Since,housing units will not be added or eliminated,no measures to reduce or control housing impacts are proposed.. 10. Aesthetics: A. What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterioc building material(s) proposed? The tallest height;of the transmission line structures will be around 105 feet. These poles are located immediately west.of SR-167 (poles 0/5.and 0/6). B. What views in the immediate vicinity would be altered or obstructed? Ifi is PSE's intention to minimally impact views along the transmission line corridor. However, based on the topography and physical limitations of transmission line construction, some views may be altered by the conductors. Pole locations have been selected to minimize potential view impacts in.the area. C. Proposed measures to reduce or control aesthetic impacts, if any: Pole locations and wi'r'e sag have been optimized to help minimize view impacts; however, it is anticipated that all impacts cannot be avoided. PSE is proposing this project in an existing fransmission line easerrient that was established prior to 1996. 11. Light and Glare: " . • - ' A. What type of light or.glare will the proposal produce? What time of day would it mainly occuc? No light or glare will be produced by.the proposed project. B. . Could light or glare from the finished project be a safety hazard or interfere with viewsT No light orglare will be produce by the proposed project; therefore, no safefy hazards would result and no views impacted. ` C. What existing off-site sources of light or glare may affect your proposal? No existing off-site sources of light or glare will impact the proposed project. ENVIRONMENTAL CHECKLIST Page 19 of 22. ` . Environmental Ghecklist (continued) . TO BE COMPLETED BY APPLICANT D. Proposed measures to reduce. or control light and glare.impacts, if any:. Since no impacts will result from light or glare originating from the proposed project; no, measures are being proposed to reduce or control light and glare. 12. Recreation: A. What designated and informal recreational opportunities are in the immediate vicinity? - PSE transmission line corridor, known as the Interurban Trail, is located along the east sid'e ofthe Christopher Substation. Additionally; there is a Homeowners Asso¢iation (HOA) maintained park located at the eastem end of South.303nd Place on the south side of the cul-de-sac (Parcel Number 289555TRCT). No other known recreational areas are located around the su6station property or along the transmission line corridor. B. Would the proposed project displace any existing'recreational uses? If so, describe. No recreational uses would be permanently displaced as a result of construction or operation of the proposed project.

Muckleshoot Indian Tribe Fisheries Division December 1, 2009 Gomments to PSE 515t Avenue S Transmission Line Page 2 Specific Comments to PSE's Christopher Substation to 51 Ave S Transmission Line project _ 1. Final Stream and Wetland Report comments 1. Stream Assessment for "KC Streaxn" located along the corridor. (Shown as Stream 0053 in Mill Creek Special Area Management Plan map 8, see http://www.nws.usace.army.miUpublicmenu/DOCUMENTS/REG/alt8.pdfl Tnformation is needed about when this stream was surveyed and the methodology used to assess bot$ the stream and the presence of fish. The report incorrectly identified this stream as a non-salmonid bearing strea.m. Coho and Cutthroat trout have been observed in this stream based on the data available for the , WRIA 9- Fish Distribution Maps. (See http://www.,govlink.org/watersheds/9/reports/FishDist.asnx). The Attribute Table for the coho map notes that there is a known fish blockage at S 277t'. The WRIA 9 . cutthroat trout map shows cutthroat trout further upstream and may include the project area. Please note tliat-human-created blockages (i.e. culvert at S. 277d) should not be used as the basis for determining fish use in strearns as these blockages can and should be removed as required by the State's Hydraulic Code. ` Fu.rther, the limited data provided for this stream in the report indicates that ttie stream width within the project area (i.e. 1-4 feet) is within the range of stream widths that aze presumed to be used by fishper WAC 222-16-031. The stream gradient for this stream within the project azea is not given in the report; . however, we suspecf that the stream gradient is less than 16% based on the elevation contour data available on:King County's IMAP. Based on these factors, we think that Stream 09.0053 is fish bearing . within the project area at least for juvenile salmonids and should be reassessed as a Class II stream for potential impacts based on this information. 2: Ditches within the.project area For the northern and southern ditches within the Christopher Substa.tion site, the information provided in the Stream and Wetland Report is insufficient to establish that these ditches aze not used by salmonids. No eIectroshocking surveys were completed and no timeframe given for when these ditches were surveyed. We have noted in many previous comment letters for various projects tha.t ditches in the Mill Creek basin may also provide overwintering habitat for juvenile salmonids. In this case, these ditches aze noted to be connected to Mill Creek, contain reed canarygrass which slows down water velocities, and are sufficiently wide and deep enough based on tlie data provided; While these ditches may be artificially createcl, NIITFD staff has found coho and cutthroat using ditches in the Mill Creek subbasin and other areas during the wet season based on electroshocking surveys. These ditches should also be presumed to be used by salmonids in the absence of sufficient data (i.e. ten years of electroshocking or fyke net data collection over various water years) to firmly establish salmonid absence. To 'facilitate the environmental review and pemutting for this proj ect, the impacts for this proj ect should consider, that these ditches are presumed to be fishbearing streams. 3. Mi1T Creek . The Stream and Wetland reports notes that there are fish, including ESA listed chinook found in Mill Muckleshoot Indian Tribe Fisheries Division December 1, 2009 Comments to PSE 515'Avenue S Transmission Line' Page 3 Creelc. The report also states that the fine, homogenous substrate of the portion of Mill Creek' within the project azea provides poor conditions for most aquatic macroinvertebrates and f sh. The report fails to note that Mill Creek is an important stream system that provides significant amounts of low gradient, reed, cariarygrass lined channels that provide lower velocity habita.ts for overwintering juvenile salmonids. While this habita.t is not necessarily in the best condition, it does provide this important function that helps overwintering juvenile salmonids survive flood conditions that can flusli them downstream before they are ready to smolt. As a result, Mill Creek should not be discounted for its value to provide overwintering habitat for juvenile salmonids. The environmental checklist notes that chinook are limited to the reach of Mill Creek downstream of SR 167 without noting that complete comprehensive surveys of juvenile chinook use ui Mill Creek fia.ve never been completed to our know:edge. See the WR.IA 9 Limiting Factors Atta.lysis for additional, information regazding salmon surveys in Mill Creek (http://vour.kin couritv. og v/dnrpLlibrarv/2000/lccr728/vo12/partIIcontinuedlno3/1VIi11Creek.pd fl. II. Project Impact comments 4. The environmental checklist for this project fails to provide sufficient details about potential project impacts. For example, on page 10, the checklist notes that three pole locations (01l, 0/2, and 0/3) will be located witlun an emergent wetland, but fail to say wluch of the 5 wetlands identified for the project will be impacted. Based on the site plan, it appears that Wetland E, the large PEM/PSS/PFO riverine wetland associated with 1VIi11 Creek and identified on the Christopher Substation site will be impacted by these three pole locations. The amount of vegeta.tion to be removed, both temporarily and permanently, associated with these three pole locations should be discussed in detail and is lacking in item 3.A.2 on page 10 of the checklist. In addition, the checklist states that "some vegeta.tion removal may be required azound the wa.terbodies and their buffers that aze situated along the transmission line corridor". The deta.ils about the amount, type and location of temporary and permanent vegeta.tion removal that may occur around the project's waterbodies, including ditches should be fully discussed. While the checklist. provides information regazding the potential removal andlor topping of up to 700 trees, without additional details, we cannot fully assess this project for its potential impacts. Furthermore, the checklist notes that there will be future transmission lines and fiber optic line installed south of the first line. Additional information about the potential to remove additional vegeta.tion from stream and wetland buffers as a result of these future lines should be provided so that potential cumulative impacts can be assessed. Finally, there are no detailed mitigation plans provided for potential impacts as a result of the proposed and potential future lines constructed along this route; therefore, we cannot evalua.te the adequacy of proposed mitigation measures to mitigate for impacts. Detailed mitigation plans should be provided. - Fage 1 of 3 .Elizabeth:Chamberlain .

Transmission Line, Application Numbers SEP09-0022, GRA 09-0010 and BLD09-0102 We were dismayed this weekend when a neighbor from a different street than ours gave us a copy of the above referenced 1Votice of Application. ThiS Notice of Application states, "This notice-has been provided to appropriate local and state agencies, and property owaers within 300 feet of the project site:" This statement alone is not true. Our property is adjacent to part of the proposed land inwhich Puget Sound Energy wishes to build high voltage power lines, and we did not receive a copy of this notice until a neighbor, going doar to door, provided us with one on 11/21/09. If we didn't receive one, it's doubtful that other property owners did as well. If Puget Sound Energy installs high voltage power lines, which are believed by many.to cause health issues, even if science has been unable to prove this yet, do they also plan to compensate us for the loss of our housing value? There will be no way to hide tlie view of these huge towers from our home, greatly decreasing the value of our home. Will there be additional noise generated by these lines after they have been constructed? In addition to the unsightliness of such power lines, the well-known belief of many people that high voltage power lines may cause healtli problems will also make it much harder to sell our homes. Yet, I see nottiing in the current proposal, nor ha.ve we been iriformed of any other proposal, to compensate Auburn's citizens for the losses they will incur. Th_ere are already high voltage power li.nes not far South from here, that come from the valley to the West and travel towards the East, far beyond 51St Avenue. Why aren't the new lines going to be installed in an already existing location,.rather than devaluing more of your citizen's property investments and possibly risking the - health of additional people that don't already live near such lines? Shouldn't the City of Auburn be considering how to make its town, businesses and residences more attractive so people want to do business in Aubum and live here? Our sixeet alone has 33 homes tha.t would be affected by building these power lines, that isn't counting homes on other streets that are adjacent to the property proposed for the new power lines. Please reject this proposal for installing new, high volta.ge power lines. ~ We also wish to receive copies of any further issues applicable to this proposal, including upcoming hearings and decisions. ` 11/23/2009 .

I am commenting , as the applicant, on behalf of my mother, for a..preliminary plat (attached), currently vested in King County (I.07P0015), across which Puget Sound Energy's (PSE's) project will run. The parcels included in the preliminary plat aze 0221049114, 0221049037, and 0221049034, the latter of which encompasses PSE's easement. My mother, Lucille Gardner, resides in a smgle-family residence on one of the pazcels and her address is 30210 56`h Ave. S., Auburn, WA 98001. Harbour Homes submitted the original plat application and had numerous dialogues with PSE regarding , their easernent (as did myfather). Tacoma Water installed a large transmission mai.n within their 100- foot easement and an acquaintance of my father planted a Christmas tree farm within that easement with approval of Tacoma Water. My father brought drainage concerns withiii the tree farm botmdaries to the ~ attention of PSE and a meeting was set up in November 2008. In advance, I had sent Heather a copy of . the plat drawing (see attached email copy dated 11/11/08). My father passed away before the meeting was held, but I met with Heather Brickey, PSE, on the site on November 25, 2008, to discuss those and . other issues. She was accompanied by Solomon Gebregiorgis, the engineerworking on the project for . , PSE. When a survey crew came out in the spring, they staked the pole locations essentially as shown on the drawings submitted to the City of Auburn. When I saw the location that interfered with access to the property per the plat dra.wing, I emailed Ms. Brickey regarding my concerns (atta.ched ema.il dated , 4/27/09) and called her when I didn't receive a response. i documented that telephone conversation in an email to my mother on 4/28/09 (atta.ched). Essentially, Ms. Brickey indicated that the project was pushed out a year and no further or immediate conversations were needed at that time. The points thaf I raised in the 4l27/09 email mclude those that I discussed with you when i visited your offices last week (on 11/12/09). The concerns with the PSE application as submitted and the design as proposed are noted below. Where they directly relate to an item in the SEPA checklist, the relevant questions/topics have been referenced. SEPA A. 9.: As noted above, a preliminary plat has been submitted fo the County and was deemed complete on 12/12/06. PSE has been aware of the preliminary platapplication that includes parcel 0221049034 for quite some time as Harbor Homes had dialogued with PSE at least as eazly at 9/5/06 (see ; attached email). On 11/11/08, I sent the preliminary plat drawing to PSE,so that they could see the plat layout that had been submitted to the Gounty. PSE's proposal adversely impacts that.proposal, particularly the location of the pole at Station 72+96. It conflicts with the proposed southern access to the plat, the route that provides the most direct route to nearby collectors and arterials. The northem access/egress winds through residential stteets and is not expected to be the preferred route to and from, the proposed development, particularly because the northem route will quickly encounter a school and proposed bike route, thereby requiring slower speeds. 1 . The proposed southern access to the three lots is the logical extension of the 60-foot right-of-way at the southwestem edge of the property. A 30-foot right-of-way extends north along the western edge of Pazcel #0221049034 until it abuts to the Lakehaven Utility District property, the site of two water towers. Because of the water tower parcel; the preliminary plat shows the proposed 60-foot right-of-way dedication veering east to border the Lakehaven property. There are no other means of access to tlie proposed plat from the south because the remaining properties that abut the parcel to the south are , developed. - SEPA A. 10.: The County has listed the cabin on Parcel #0221049034 on the County's Historic Resource Inveritory. The County indicated, in an email to Harbour Homes (11/7107, atta.ched) that, if federal funds were used for its project or PSE work, an additional review and, possibly, mitigation would be required. - The list of approvals does not appear to account for this item. I discussed this during PSE's site visit on 11/25/08 and indicated that I would be willing to prepaze a report upon their request; the offer was never acted upon. SEPA B 4.B.: In the table that list the trees that will be removed, the Gardner parcel_is listed as containing the most, 210 trees. We own the trees and there has been no communication with us as to their removal including their value and how we will be compensated for them, whether we would have the opportunity to fell some of the trees for our own personal use, and how the property will be left once the tree removal and pole erection has taken place. I encountered PSE's arborist on the property one day and discovered that they were considering a haul route over the already-cleazed part of the easement within which the water transmission main was installed. However, a Christmas tree fazm has been planted there and would need to be protected or a separate route used that avoids the trees. Also, Tacoma Water may need to be approached if PSE proposes to use heavy vehicles in the vicinity of their pipeline (which - includes a large exposed valve at the top of the rise) as the alignment is clearly not in a roadway. SEPA B 8.B.c I confirm that there is a Christmas tree farm on Pazcel #0221049034. My father wanted to improve the aesthetics of the water lransmission main alignment and allowed an acquaintance of his to plant a Christrnas tree farm. It is still in the "growing" stage and sales ha.ve not yet occurred. SEPA B 8.ID.: Please see the comments under SEPA A. 10. The County has listed the cabin on Parcel #0221049034 on the County's Historic Resource Inventory. SEPA B 8.J/K.: As shown on PSE's current drawing, the PSE project would displace the residents of 79 homes that are proposed for development in the preliminary plat application currently on file with King County. Please see the above information regarding the application. Thus, I requestthat PSE be required• to take measures to avoid displacement. SEPA B 8.L.: As shown on PSE's current drawing, the PSE project is not compatible with land use planning and zoning codes in that it conflicts with the preliminary plat applicarion that is on file with the County and which has been submitted in accordance planning documents. The Growth Management Act mandates dense growth in urban azeas. In fact, King County has a worksheet that requires a minimum density that nearly matches maximum density for any given pazcel. Pole placement that conflicts with a proposed right-of-way dedication denies access to the three parcels and their development in accordance with the County,'s zoning and land use codes. I assume the preliminary plat would not be allowed to go forward without this southem access; roads continue to be the main focus of the County in processing this application. SEPA B 9.B/C.: See the SEPA B.8. answers above. Essentially, the PSE project does eliminate 79 middle-income houses. ~ SEPA B 10.: The existence of the powerlines will certainly reduce the value of the adjacent proposed development and so we are shouldering definite negative economic impacts because of PSE's project. 2 - .And yet, we have tried to be cooperative with PSE in moving their project forward. We feel they should . reciprocate and site their poles to be consistent with and accommoda.ting to the proposed plat. SEPA B 12.: Camp Fire USA holds day camp on the site every summer for two weeks in July. Frior to that, volunteers from local businesses come and spruce up the site for day camp and Camp Fire volunteers train on the site. Boy Scout groups and local families have also used the site for camping. Camp Fire USA's schedule of use can be determined and we have asked PSE to consider their schedule and the safety of the campers during that time. We hope that such considera.tions can be made a condition of PSE's perniits. SEPA B 13.: Please see the comments under SEPA A.10. The County has listed the cabin on Parcel #0221049034 on the County's Historic Resource Inventory. SEPA B 14.G.: Please see the previous comments regarding compatibility of PSE's project with the ~ proposed right-of-way dedication associated with the Gardners' preliminary plat application. I am concerned about the cleazance required azound each PSE pole and ask that the City of Auburn , require PSE to provide the pole locations and type of construction that will accommoda.te the proposed right-of way dedication and associated use (i.e., traffic associated with construction of the plat and use once it has been developed). . At this point; it is easier for PSE to make modifications to accommodate the preliminary plat project that has been.designed much earlier than PSE's project than it is to have to move PSE installations in the future. I have tried to be proactive with and responsive to PSE, but the communication has only been one-way.

Meeting with your dad and mom on Thursday at 9:30 just to sit and talk about where we are and where we need to get fo in terms of the contract offer. I have a meeting tomorrow with PSE to discuss the regio.nal utility coRidor and our request to reduce the area on the property. I told your dad I would like to go through his list of items - though he mentioned getting some feedback from Pat on them? I can tell you that our offer will be very similar to whaf you have already seen. I need to really get a survey crew out to map out the house and where it exactly fits in our.layout. Keeping the. house may cause a reduction in the number of lots due to its proximity to the road, we _ may need to jog the road further north which would wipe out lots.

It is currently undergoing review with the County: I request that you do not contact the engineer, D.R. Strong, regarding this projecf, but rather go through me first. I have . manyof the documents that were submitted to the County(or can get copies of them) and am just trying to keep oar costs down. We don't.have a lot of money to spend and I get charged everytime the engineer does something on this project...but there were a lot of advantages to continuing the preliminary plat process. As we discussed; the "drainage problem" my dad talked about may be in referenceto his dissatisfaction with the backfill and topsoil placement as performed bythe ufility district during the recent installation of the water transmission line.

I am concemed that there has been no communication regarding this and would like to talk to someone regarding: 1) Notifying the owner (Lucille Gardner) whenever you plan to be on the property. 2) How your pole placement can be facilitated in light of the preliminary plat application with the County. 3) Marketing of the frees that will be harvested. ~ 4) Protec.tion of the Christmas tree farm as the clearing is done. 5) Timing of tFie cleacing to avoid conflicts with the annual Camp Fire Day Camp that occurs in July. (We have previously reguested consideration that clearing be performed after day camp.) While there may be confusion regarding ownership of the property because the King County assessors office chooses to not list the "majority" owner of the prope►ty (the Gardner Family Trust)-1'll be forcing the issue with King County, I'm shocked fhat PSE is nof communicating with the Gardner family.

She had just gotten back from some time off, thus the.delay in returning my emaiL , She indicated that there will be no construction this year because ofi permitting issues. Specifically, because Aubum has put a moratorium on issuing permits for projects in the Green River floodplain until June, PSE's window for construction was closed. So they are putting the project off for one year. They did, however, come out and spray around-their survey stakes so that they could fnd them next year! And I suppose they may do that occasionally throughou# the growing season. It sounds as if Day Camp is very much on their[adar screen and she promised to take that into consideration for nexf year, as well. PSE would like to demolish the, cabin fhis year in late summer and will coordinate with us. I told her thaf Ray keeps his equipment for the Christmas tree farm in #here, so she's aware of it and that it will need to be taken into considerafion befbre it is demolished: I guess I'll' save my questions for her until next year!

Aubian, WA 98001 Dear Ms. Gardner, I am writing in r~Ponse to Your:concems regarding ` : - _ the Christopher Substation to 5 i Avenue Sou(-h T*arsmieC;on lin.e project in the City of Auburn. You have asked that the trarnsmmon pole at Station 72+96 be located so that it does not conflict with the proposed access to the preIiminaty plat applicationfor parcel. 0221049034. PSE has re-designed the plan so that the pole will not be in contlict with the proposed access or,tlie,ProPosed ten foot utility easement planned for that plat This is based on the plans available today. Should the plat plMs change and aegatively impact the in.stalled transmission line and poles, any relocation cost will become the responmbility of the,developer. -This d.esiga requires that the exispng gravel access to the property to be relocated aroa.ad the new pole location which has be incorporated iat.o the re-desitgn. I have included a copy of the final design with the revised pole Iocatian. . Yon asked about the value of the trees that are being rem.oved. on the Right-Of-Way (ROw). When.the easement was:obtained in 1981 tbrough King Couatp 3uperior Court Cause Number 80-2-15783-3, I1oyd and. Lueille Gardner were campensated for the right granted Puget Sound Energy's predecessor, for an initial removal of a1l:trees, brusk, and . other vegetat.ion which rnay be oa the ROW. The initial "cutting" has aof taken place ' . yek Additionally, the Judgment and Decree, out of said cov:rt action states that the property owner shall be compensatod for anp tree removals, subsequent to the initial cufting. Any trees ouiside of the ROw that are deemed to be a hazazd would; need to be removed but of couzse, the groperty owner would be reimbursed. the market value of any . merchantable timber those tree's wonld yield At tbis .time there are no tree's identified to be removed ovWde the`ROW. Per the teims of said easement, should anp such tree now or in the fiifure be identified the property owner w11 be given written notificati.on before it is removed msless emergeacy conditions make prior notification mpractical. Yon asked about the Christmas tree fazm that was plantsd bp a family friend and requested that it be prot.ected d, ring the canstrv,ction. Specificaliy we believe thatyour concerns are regarding a hanlmg road that was meIItianed by one of PSE's azborists that . . you met on site. PSE is not Planning tu use a haulmg road and agrees ta Ieave the, Ghrislmas tree farm in place as long as fihe heighis of the trees do not grow to a height that is ia contlict with the safety cleazances that are iequired or future phases of . ' construetion. ; . ` . , . - , Yon asked abouf the Campfire.Crirls Summer Camp that is held on your property and thaf arrangs aTe mad.e so that the canstraction of the project will not confliet with . . activities of the da:y camp. I have contacted the Campfire Girls organizationaud the _ summer camp activities are scheduled between July 9ffi and Augnst 8&;2010. We agree to not have any construction activity occur on your properiy during the camp activities. You asked abouf access to your propeaiy diuing construction. Access will be mai,;Wned, . a# all tim:es. During svme consh action activities it ma.y be necessary to redirect access for safefy reasons. Access however will be maintained to the ProPerlY at all times. , You asked about the exi.sting utilities. Utility locates will be done in accordance with;the Ca11 before You Dig laws and a11 egisting utilities will be main.tamed. Also, in regards to, the Tacoma Wafer Distriat recently installed water PiPe, PSE will nolafy Tacoma Water_ of theproject and wilt adiiere to the Muiual Uae Agreement between PSE and Tacoma. Water. You asked about communication before and dumng construction. A canstruckion notice will be sent out one to two weeks prior to=the commencemen.t of construction. Also y,ou will be notified 24 to 48 houis before any ciews are on site to perfoan any work. I also can be contacted at`.any time if the2e are questions or concems' during construction. You asked about'the restoration and whai was to be done with the materials that aze cleared. It is onr intention to leave=the understary as much as .possible including the stumps and roots of the removed tree.s but the debris from the tree clewing, such as braaches, w7I lie removed = The trees renwved will be hauied off site. If pou would h-ce to retaan some of the -wood for personal use, please let me know and I will try to accbmmodate yout request FinaIly, you asked aboutthe log cabin on your praperly that is on your property and is on the Counties Mstoric Resource Inventory. PSE will not dishirb tlie cabin, so no adclitionai sfudies are required. I ha.ve included the information regarding the cabin from the cuitural study report doae with this letter. . .

This line will be built in a right-of-way (ROW) that is already fee owned or for which there is an existing easement. There will eventually be three 115-kV transmission lines in the proposed route. This report assesses the potential impacts to wetlands from the proposed project, and provides recommendations for mitigation in accordance with the permit requirements and regulations found in Chapter 16.10 of the Auburn City Code, which is the Auburn Critical Areas Ordinance. Wetlands on the project site were delineated by AECOM in March and April of 2008. The results of that delineation are referenced and summarized in this mitigation plan, and the full wetland delineation report is provided as an Appendix. 1.2 Project Contacts Property Owner/Applicant: Puget Sound Energy (PSE) Attention: Brad Strauch P.O. Box 97034 EST 11-W Bellevue, Washington 98009 (425) 456-2556 Authorized Agent: AECOM Kim Anderson, Project Manager 710 Second Avenue, Suite 1000 Seattle, Washington 98104 (206) 624-9349 Tina Mirabile, PWS 401 Harris Avenue, Suite 200 Bellingham, Washington 98225 (360) 647-0990 x18 Christopher to 51s' Mitigation Plan April 2010 AECOM Report Environment 2-1 2.0 Proposed Project and Site Description 2.1 Overview The proposed corridor for the new 115-kV overhead power transmission lines (project corridor; project area) is located in Sections 1, 2, 3, 10, 11, and 12 of Township 21 North, Range 4 East, within the City of Auburn, King County, Washington (Figure 2-1). At its west end, the proposed project corridor begins at the intersection of 51 st Avenue South and South 304th Street. The corridor runs roughly east for approximately half a mile, and then heads northeast for about a mile, past the West Valley Highway and State Route 167, ending at the Christopher Substation south of 37th Street NW. Along most of its length, the corridor has a width of 200 feet; however, the width is reduced to 100 feet as it approaches the substation. Much of the project corridor was annexed to the City of Auburn at the beginning of 2008. The project area is located entirely within the Green/Duwamish River Watershed, and in the Lower Green River subwatershed. The major tributary running through the area is Mill Creek. West of the West Valley Highway, the project corridor is located near residential development, in areas that are zoned for residential and industrial uses. Along a portion of its length, an existing Bonneville Power Administration (BPA) transmission line runs adjacent to the project corridor. The western portion of the project area is zoned for residential use; single-family residences, and some areas of open and public space are present. East of the West Valley Highway, which includes the PSE-owned parcel on which the Christopher Substation is located, zoning and land use within the project corridor is light industrial. 2.2 Project Description The proposed project will entail placement of transmission line poles along the project corridor, and installation of three 115-kV transmission lines. The lines will tie into the Christopher Substation on the eastern end of the proposed project corridor, and into existing lines at 51 st Avenue South on the western end. The total area covered by the proposed project corridor shown in Figure 2-1 is approximately 33 acres (13 hectares). Within the project corridor, all trees will be cleared to provide clearance for the lines, although some trees may be girdled and left in place as snags. The total width of the corridor to be cleared is 200 feet, which includes required buffers on either side of the transmission lines. Approximately 700 trees will be removed from the transmission line corridor, approximately one-third of which occur in wetlands and City-regulated wetland buffers. Project activities at the substation site will require removal of 37 trees from wetland habitats. Along the remainder of the project corridor, numerous trees will be removed from wetlands and wetland buffers. Figure 2-2 shows an overview of the wetlands and streams located along the project corridor. These impacts are discussed in more detail in Chapter 3.0. Within wetland areas, no grubbing, stump removal, or other associated land disturbances will occur, and no mechanized equipment will be used. Hand equipment or pickers that extend over wetlands will be used in wetland areas. As appropriate, some felled trees and branches will be left on the ground as woody debris. Limited use of mechanical equipment will occur in the wetland buffers. Numerous transmission line poles will be located along the proposed corridor. Each pole installation will require the augering of a hole 3 feet in diameter and 8.5 to 11.5 feet deep, depending on the pole height. Following pole placement, holes will be backfilled with gravel, and spoils will be hauled off site. For the most part, poles will be located in non-regulated upland areas, outside of wetlands, streams and Christopher to 51s' Mitigation Plan April 2010 AECOM Report Environment 2-2 associated protective buffers. However, at the Christopher Substation Site, a total of seven poles will be placed within wetland habitats. Additionally, one pole will be located in a wetland buffer. In wetland areas, mats will be laid down on the ground surface to temporarily provide vehicular/equipment access to pole locations. The mat "access route" will be approximately 8 to 10 feet wide. In order to reduce impacts associated with soil compaction and rutting from heavy equipment and or vehicle use within the wetland areas, pole transport and installation at the substation site will be scheduled for the driest part of the year (likely August), and will not take longer than 2 months to complete. The mats will be removed after project work within the respective area is complete. All staging areas and equipment storage will take place at the Christopher Substation, on top of existing concrete surfaces. Poles would be carried above the ground surface prior to installation, rather than dragged. In other portions of the project corridor, work sites will be accessed along existing paths and access roads. It is not anticipated that additional access roads will need to be created, although existing trails could be improved by resurfacing. Resurfacing will not occur on existing roads or trails that occur in wetlands or wetland/stream buffers. Should it be determined at a later date that additional access roads are required, these roads would not be located in wetlands or wetland/stream buffers. 2.3 Project Site Description The area within the project corridor supports a mix of open, grassy areas and second-growth forest. Remnants of past land uses, such as abandoned buildings, overgrown gravel roads, and areas of fill, are present, indicating that the site has been disturbed to varying degrees. Roughly midway through the project corridor, a stream runs north-south through the area, and is associated with a fairly large wetland complex (estimated at 6 acres in size). The forested portion of the corridor immediately to the west of West Valley Highway is predominantly a steep hillslope. Open, grassy areas are prevalent along the project corridor. Various species of grass are present, but the dominants are orchard grass (Dactylis glomerata) and bentgrass (Agrostis spp.). Meadow buttercup (Ranunculus acris) is common in moist to wet areas. The most prevalent shrub is Himalayan blackberry (Rubus armeniacus). In moist areas, forested stands consist of mostly red alder (Alnus rubra), often with an understory of Himalayan blackberry. The forested area in the eastern portion of the corridor has an overstory of Douglas-fir (Pseudotsuga menziesh), red alder, and bigleaf maple (Acer macrophyllum). Red elderberry (Sambucus racemosa) is prevalent in the understory. Common herbaceous species include stinging nettle (Urtica dioica), sword fern (Polystichum munitum), and Pacific waterleaf (Hydrophyllum tenuipes). Soils along most of the project corridor are mapped as Alderwood gravelly sandy loams, with slopes ranging from 0 to 30 percent. These are moderately well drained upland soils that formed in glacial deposits under conifers. In the steep area at the east end of the project corridor, soils are mapped as very steep Alderwood and Kitsap soils. The erosion hazard in this area is severe to very severe. The Christopher substation site predominantly supports herbaceous vegetation, with reed canarygrass (Phalaris arundinacea) as the dominant species, forming a monoculture in many areas. Mill Creek runs through the site, with two main north-south channels. At a few scattered areas within the stream channel, patches of cattail (Typha sp.) are present. Scrub-shrub vegetation is found along portions of the stream channel and drainage ditches, as well as between forested stands southeast of the substation. Scrub-shrub vegetation predominantly consists of Douglas Spirea (Spirea douglash), Himalayan blackberry, and red-osier dogwood (Cornus sericea). In the north half of the site, forested areas occur near the substation and along the stream channel. Dominant tree species include black cottonwood (Populus balsamifera ssp. trichocarpa), red alder, and willows (Salix spp.). Soils on the substation site are mapped primarily as Oridia, Renton, and Norma series soils, with a small area of Puget series soils (USDA Soil Conservation Service 1973). The Oridia and Renton series are somewhat poorly drained silt loams that formed in alluvium in river valleys. The Norma series are sandy Christopher to 51s' Mitigation Plan April 2010 AECOM Report loams that occur in basins and along stream bottoms. loams that formed in small depressions of river valleys percent. 2.4 Wetlands and Associated Buffers Environment The Puget series are poorly drained silty clay . The slopes of all these series are less than 2 A total of five wetlands were delineated in the project area, as summarized in Table 2-1, depicted in Figures 2-3 through 2-7, and discussed in more detail in the Christopher Substation to 51St Avenue South Wetland Delineation and Stream Assessment (ENSR Corporation 2008), which has been provided as Appendix A to this report. Wetlands A through D are located along the proposed transmission line corridor, and Wetland E is located on the Christopher Substation Parcel. The total wetland area within the proposed project corridor is 153,553 square feet (3.5 acres). Table 2-1.

Wetlands A and B are very small Palustrine Emergent (PEM) wetlands located in the proposed transmission line corridor. Wetland A is a Category IV wetland located in an open, disturbed area at a site of possible fill deposition. Dominant species include orchard grass, creeping buttercup (Ranunculus repens), and common velvetgrass (Holcus lanatus). Wetland B is a narrow ditch, approximately 2 feet wide, with banks about 1 foot high, that appears to serve as a channel for surface water from upslope areas during wet periods. Dominant plant species include creeping buttercup, bentgrass, orchard grass, and stinging nettle. The wetland is located between two moist forested stands. It has been classified as a Category IV wetland. Wetlands A and B have moderate water quality functions but low hydrologic and habitat functions. Wetland C is a large, Category II PEM/Palustrine Forested (PFO)/Palustrine Scrub-shrub (PSS) wetland associated with a stream channel that extends beyond the proposed transmission line corridor to the north and the south. Approximately 1 acre of this wetland is located within the project corridor, but the entire wetland is much larger. The emergent portion is dominated by bentgrass, orchard grass, tall fescue (Schedonorus phoenix), and meadow buttercup. In the wetter portions, common rush becomes more prevalent. The forested portion of the wetland is a riparian area along the stream channel. The Christopher to 51s' Mitigation Plan April 2010 AECOM Report Environment 2-4 predominant tree species is red alder, with a Himalayan blackberry understory. The scrub-shrub portion of the wetland is dominated by Himalayan blackberry. Wetland C has a high potential, and the opportunity, to reduce flooding and erosion and improve water quality. Wetland D is a small, Category I I I PEM/PSS/PFO wetland, approximately 0.3 acres (14,300 square feet) in size. The emergent portion is dominated by orchard grass, common rush, and meadow buttercup, with small areas of reed canarygrass. The dominant tree in the forested portion is red alder, and understory dominants include Himalayan blackberry and Indian plum (Oemleria cerasiformis). Herbaceous dominants in the forested portion include meadow buttercup and large-leaved avens (Geum macrophyllum). The scrub-shrub portion consists almost entirely of Himalayan blackberry. Wetland D has low hydrologic functions and moderate water quality and habitat functions. Wetland E is a single, large, Category II PEM/PSS/PFO riverine wetland complex that occupies the majority of the Christopher Substation site. The PEM component is predominant (46.6 acres), followed by PFO (8.4 acres) and PSS (4.0 acres). However, only a small portion of this wetland complex is within the proposed project area. Within the PEM component reed canarygrass forms a dense coverage of most of the wetland, and dominates many of the upland inclusions as well. In the forested wetland portions, red alder is the most common species, with willows as an associate along streams, and black cottonwood as an associate in other areas. The PSS component occurs primarily along portions of the creek and drainage ditches. Dominant species are rose spirea (Spirea douglash) and red-osier dogwood (Cornus stoloniferia), with some Himalayan blackberry where the wetland is transitioning to upland. Wetland E has moderate water quality functions, and high hydrologic and habitat functions. 2.5 Other Aquatic Resources and Associated Buffers Two streams were identified within the project area: Mill Creek, which runs through the Christopher Substation site, and a lesser order stream, referred to as "Tributary 0053, Mullen Slough" in correspondence from the City of Auburn, and as "KC Stream" by King County GIS layers (the name used in the delineation report). In this report, it is called Stream 0053. These streams are depicted on Figures 2-3 through 2-7 and discussed in detail in the delineation report. Mill Creek is a Class II salmonid-bearing stream with an average wetted width of 15 feet that splits into two branches on the Christopher Substation site. It has a hydrologic connection to the Wetland E wetland complex. Tributary 0053 flows roughly to the north through the project corridor. It is a Class III stream with a width that varies from 1 to 4 feet and has minimal habitat complexity. It has a hydrologic connection to Wetland C. 2.6 Wildlife Use of the Project Site Several species of bird were seen or heard by AECOM biologists during site investigations, primarily in patches of forested habitat in upland and wetland areas. Species noted within the project corridor include American crow (Corvus brachyrhyncos), American robin (Turdus migratorius), Steller's jay (Cyanocitta stellen), northern flicker (Colaptes auratus), dark-eyed junco (Junco hyemalis), black- capped chickadee (Poecile atricapilla), and pileated woodpecker (Dryocopus pileatus). Additionally, an active red-tailed hawk (Buteo jamaicensis) nest was observed at the east of the project corridor, near the West Valley Highway. The only mammal encountered was a rabbit or hare of unknown species. The pileated woodpecker is a Washington State Species of Concern, with breeding areas considered Priority Habitat areas. AECOM biologists did not confirm the presence of breeding areas in the project corridor; it is more likely that suitable breeding habitat would be located in the forested area to the north of the project corridor. Christopher to 51s' Mitigation Plan April 2010 AECOM Report Environment 2-5 At the Christopher Substation site, AECOM biologists noted coyote (Canis latrans) scat in numerous places along grassy roads/trails within the site. Bird and waterfowl species observed along and near Mill Creek include American bittern (Botaurus lentiginosus), black-and-white warbler (Mniotilta varia), hooded merganser (Lophodytes cucullatus), mallard (Anas platyrhynchos), marsh wren (Cistothorus palustris), and song sparrow (Melospiza melodia). Near the drainage ditch along the site's eastern boundary, American crows, hooded mergansers, red-winged blackbirds (Agelaius phoeniceus), and brown-headed cowbirds (Molothrus ater) were observed. Bird species observed in forested areas at the north end of the site include downy woodpecker (Picoides pubescens), black-capped chickadee, American robin, and song sparrow. Marsh wren was common at the site, and was heard in many locations within emergent wetland areas dominated by reed canarygrass. Two great blue herons (Ardea herodias) and a northern flicker were seen flying over the central portion of the site. An active red-tailed hawk nest was observed near the southwest corner of the substation. The great blue heron is considered a Priority Species by Washington Department of Fish and Wildlife (WDFW), and its breeding areas are considered Priority Habitats. No great blue heron nests were observed in forested areas on the site; therefore, use of this area as breeding habitat cannot be confirmed. The observed birds could possibly be part of a large breeding colony of herons documented by WDFW at a location approximately 2 miles south of the substation site. The northern boundary of the associated priority habitat area, as mapped in Priority Habitats and Species (PHS) data from WDFW, is approximately 400 feet south of the Wetland D buffer. The wetlands on the Christopher Substation site are also mapped as general Priority Habitats by WDFW. No fish were observed in any of the water bodies in the project area (Stream 0053, Mill Creek, or associated drainage ditches). However, according to data from WDFW, the old Mill Creek channel has documented presence of chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch), and cutthroat trout (O. clarkii), and presumed presence of steelhead trout (O. mykiss). Mill Creek is also designated Critical Habitat for chinook salmon. Additionally, there is documented presence of coho salmon in the southern drainage ditch on the property. Stream 0053 within the project area is not shown on PHS maps; however, there is presumed presence of cutthroat trout and coho salmon more than 1,500 feet downstream of the project site.

Wetland Mitigation Plan 60145300 2-1 2 April 2010 AECOM Report Environment 3-1 3.0 Wetland Impact Assessment The proposed project will result in direct impacts to wetlands and buffers in the project area, as summarized in Table 3-1. Table 3-1. Potential Impacts to Wetlands and Buffers from the Proposed Project. N Grading and Fill for Poles Tree Removal ame Wetland Buffer Wetland Buffer Wetland A None None None 6 trees Wetland B None None None 12 trees Wetland C None 28 sq ft 128 trees 40 trees Wetland D None None 13 trees 32 trees Wetland E (Substation Site) 200 sq ft None 37 trees 82 trees Total 200 sq ft 28 sq ft 178 trees 172 trees Mill Creek and Stream 0053 would not be impacted by the proposed project. However trees would be removed from City-regulated buffers associated with both streams. In the case of Stream 0053, the buffer is entirely within Wetland C within the project corridor, and therefore impacts associated with tree removal within the buffer would be addressed under wetland impacts. In the case of Mill Creek, the stream buffer within the project corridor extends approximately 30 feet beyond the City-regulated buffer for Wetland E. Figures 2-1 through 2-5 show where wetlands and wetland/stream buffers intersect the project corridor, and pole placements in relation to these sensitive areas. Appendix B provides detailed lists of trees identified for removal from project area wetlands and buffers. 3.1 Wetland Fill Placement of poles will result in approximately 200 square feet (0.005 acres) of fill into PEM areas in Wetland E. No wetland fill or other loss of wetlands will occur in Wetlands A through D. 3.2 Tree Removal from Wetlands At the Christopher Substation site, a total of 37 trees will be removed from forested wetland areas. Trees identified for removal include 32 black cottonwoods (ranging from 5 to 24 inches diameter at breast height [dbh]) and five alders (ranging from 4 to 12 inches dbh). Along the rest of the project corridor, a total of 141 trees will be removed from forested wetland areas at Wetlands C and D. At Wetland C, 128 trees will be removed: 124 red alders ranging from 1 to 14 inches dbh, 3 small hollies, and 1 willow. At Wetland D, 13 red alders ranging from 1 to 17 inches dbh will be removed. Removal of trees will not constitute a loss of wetlands, but will result in a long-term conversion of forested wetland to scrub-shrub, and a reduction in some wetland functions, as described in more detail in Section 3.4. Removal of trees from wetlands can affect hydrology by raising the level of the water table. Such an increase could potentially result in increased flows in nearby streams. In the case of Stream 0053, it is Christopher to 51s' Mitigation Plan April 2010 AECOM Report Environment 3-2 expected that any effects on water flows would be minor, given the extent of the tree removal. Most of the trees identified for removal from the wetland area are small to medium-sized red alders, none of which are located closer than 10 feet to the stream channel. The mitigation discussed in Chapter 4.0 would compensate for any changes to the water regime that might occur. 3.3 Tree Removal from Wetland and Stream Buffers Removal of trees will result in a long-term conversion of some forested habitats to scrub-shrub habitats, as discussed further in Section 3.4. A total of 90 trees have been identified for removal from the City- regulated buffers of Wetlands A through D. In the buffer of Wetland A, four small vine maples and two small cottonwoods will be removed. In the buffer of Wetland B, 11 red alders (ranging from 5.5 to 16.6 inches dbh) will be removed, along with one Douglas-fir (29 inches dbh). In the buffer of wetland C, 34 red alders (ranging from 1 to 15 inches dbh), four Douglas-firs (14 to 29 inches dbh), and one fruit tree (14 inches dbh) will be removed. In the buffer of wetland D, 16 hollies (1 to 4 inches dbh), eight unidentified ornamental species (3 to 16 inches dbh), six red alders (6 to 15 inches dbh), two willows (3 and 6 inches dbh), and one walnut tree (22 inches dbh) would be removed. A total of 82 trees have been identified for removal from the wetland and stream buffer at Wetland E. The majority of these tree are small willows growing in clumps. A total of 64 willows (ranging from 2 to 11 inches dbh), eight maples (ranging from 1 to 4 inches dbh), seven western redcedars (ranging from 2 to 4 inches dbh), and three douglas-firs (ranging from 1 to 3 inches dbh) will be removed. 3.4 Conversion of Forested Wetland and Buffer Habitats to Scrub-Shrub Habitats Cutting of trees within wetland and buffer areas will result in the long-term conversion of forested habitats to scrub-shrub habitats in the areas where tree removal is to occur. Plant communities in scrub- shrub wetlands and upland buffers typically provide functions at moderate levels, as compared to the higher levels of functions provided by forested habitats. Although trees are to be removed from forested portions of the project area, existing shrub and ground cover will be retained to prevent soil erosion and to continue to provide moderate infiltration and habitat functions. The mitigation discussed in Chapter 4.0 is prescribed to replace lost tree canopy with dense and diverse native shrub habitats, and to enhance lower functioning emergent wetland and upland meadow habitats in adjacent areas. Christopher to 51s' Mitigation Plan April 2010 AECOM Report Environment 4-1 4.0 Proposed Mitigation Approach 4.1 City of Auburn Mitigation Standards The Auburn City Code requires that adverse impacts to critical area functions and values be mitigated as follows: The preferred location of mitigation is on-site. Mitigation may be allowed off-site only when it is determined that on-site mitigation is not scientifically feasible or practical due to physical features of the property, or where the affected site is identified as appropriate for off-site mitigation in the Mill Creek Special Area Management Plan. When mitigation cannot be provided on-site, mitigation shall be provided in the same drainage basin as the permitted activity on property owned, secured, or controlled by the applicant where such mitigation is practical and beneficial to the wetland and associated resources. Mitigation sites shall be located within the city. 2. In-kind mitigation shall be provided, except where the applicant demonstrates that greater functional and habitat value can be achieved through out-of-kind mitigation. 3. When wetland mitigation is permitted, the mitigation project shall occur near an adequate water supply (river, stream, groundwater) with a hydrologic connection to the wetland to ensure successful mitigation or restoration. 4. The mitigation plan shall be completed before initiation of other permitted activities, unless a phased or concurrent schedule that assures completion prior to occupancy has been approved by the department. 4.2 Mitigation Sequencing Given the existing environmental site conditions and project-specific infrastructure requirements, impacts to portions of wetlands and buffer areas within the project area are unavoidable. However, PSE has designed the project to minimize impacts associated with pole placement and site access. Proposed pole locations along the majority of the project corridor would be outside of wetlands and City- regulated buffers. One exception is at the Christopher substation site, where the extent of wetlands (covering nearly all of the site) makes avoidance of pole placements within wetland areas impossible (Figure 2-6). Another exception is at Wetland C, where one pole would be located at the outer edge of the western buffer (Figure 2-5). Additionally, PSE will take further steps to minimize wetland impacts, including laying down mats instead of creating access roads, timing work within wetlands during the driest time of the year, and using equipment and harvesting techniques to avoid ground disturbance in wetlands. In December 2009, PSE met with planners from the City of Auburn to discuss appropriate mitigation for potential project impacts. The City indicated that impacts to Wetlands C and E would need to be compensated for on-site through appropriate mitigation measures. The City also recommended that any impacts to wetlands B and D could be mitigated for on the Christopher Substation property (Wetland E). 4.3 Pertinent Regulatory Information According to Section 16.10.100 of the Auburn City Code, no overall net loss will occur in wetland or stream functions and values, and "mitigation shall be functionally equivalent to, or greater than the Christopher to 51s' Mitigation Plan April 2010 AECOM Report Environment 4-2 altered wetland or stream in terms of hydrological, biological, physical, and chemical functions." The following replacement and enhancement ratios are provided. Table 4-1. Wetland Replacement and Enhancement Ratios under Auburn City Code Wetland Category Wetland Creation Ratio (acres) Wetland Enhancement Ratio (acres) (Acres Created or Enhanced: Acres Impacted) Category 1 6:1 12:1 Category 11 Forested 3:1 6:1 Scrub/Shrub 2:1 4:1 Emergent 2:1 4:1 Category III Forested 3:1 6:1 Scrub/Shrub 2:1 4:1 Emergent 2:1 4:1 Category IV 1.25:1 2.5:1 Source: Auburn City Code 16.10.110 The City Code also states that the department may vary these standards if it is agreed that "the variation will provide adequate compensation for lost wetland area, functions, or values, or if other circumstances as determined by the directorjustify the variation." However, the amount of mitigation cannot be less than the area of affected wetland (except in certain cases for Category IV wetlands). During the November meeting between City planners and PSE, there was a brief discussion about mitigating for impacts that will result in a long-term conversion from forested to scrub-shrub wetland habitats. PSE wondered how to best mitigate for this type of impact, which does not result in a loss of wetland area, but does result in some loss of functions. The City's recommendation was to present recommendations on how to best mitigate for these impacts, which are discussed in Section 4.3 below. 4.3 Proposed Mitigation 4.3.1 Mitigation Approach PSE proposes to mitigate for wetland losses due to fill for poles at the standard ratios presented in Table 4-1. In areas of wetland conversion from forested to scrub-shrub, PSE proposes to mitigate for tree removal by planting four native shrubs for each tree removed, regardless of size. Because the impacted wetlands have been degraded by past site uses and do not have large forested components or high habitat functions, the level of function that would be lost as a result of project activities is much less than would occur at intact forested wetland communities. The proposed native shrub installations will fill in the canopy cover lost due to tree removal, and will also enhance adjacent emergent areas, as the area needed for shrub plantings will be larger than the area occupied by the tree being removed. This will result in enhancement of degraded emergent wetland communities dominated by non-native grasses. In wetland buffer areas, PSE proposes to compensate for loss of canopy cover by replacing each tree less than 20 inches dbh with 1 native shrub, and replacing each tree 20 inches dbh or greater with 3 native shrubs. Details about the amount of mitigation required for impacts at each wetland, and the proposed location for this mitigation, are provided in Section 4.3.2. Christopher to 51s' Mitigation Plan April 2010 AECOM Report Environment 4-3 4.3.2 Mitigation by Wetland Table 4-2 summarizes impacts associated with tree removal within wetlands and wetland buffers, and the number of shrubs that will be required for installation, based on the proposed shrub replacement ratios. A total of 894 shrubs will be required for installation to mitigate for impacts associated with removal of trees from wetlands and buffers. At wetland E, an additional 800 square feet of enhancement plantings will be required to mitigate for fill in 200 square feet of wetlands at the required 4:1 enhancement ratio for impacts to Category II PEM wetlands. This mitigation will require installation of an additional 32 native shrubs, bringing the total shrub count to 926. Table 4-2.

N/A = not applicable The proposed native shrub plantings are intended to prevent encroachment of non-native species and increase native plant diversity within altered portions of the project site. Additionally, the plantings will provide moderate shade and habitat functions to adjacent wetland emergent and upland meadow buffer areas where canopy species are currently lacking. All impacts to wetland buffers will be mitigated for at the site of impacts. These areas are generally shown as forested buffer areas in Figures 2-3 through 2-6, although site conditions may have changed since 2002 when the aerial photographs were taken. Most prominently, the area surrounding Wetland A has been cleared and only a small portion of the buffer is currently forested. Because of an existing water line and other constraints associated with private properties, Wetlands A, B, and D were not feasible locations for mitigation of impacts to wetlands in the project corridor. As recommended by the City, the proposed location for mitigation of impacts to Wetland C is at Wetland C, and the proposed location for mitigation of impacts to Wetland D and Wetland E is at Wetland E. Wetland C Mitigation. Mitigation plantings at Wetland C will occur within the yellow hatched area in Figure 2-5, over a total estimated area of 35,000 square feet. This area includes forested areas from which trees will be cut, as well as emergent wetland areas on the site. It is estimated that after tree removal, the current forested wetland area (17,900 square feet) will provide enough space for one-third of the total number of shrubs needed for mitigation (as presented in Table 4-2). The remaining two- thirds of the shrubs, based on standard spacings, will be installed over an area of approximately 17,100 square feet of adjacent emergent wetland habitat. The ratio of the total planting area to impacted Wetland C forested area is approximately 2:1. Wetland D Mitigation. Based on the recommended plantings presented in Table 4-1, an area of approximately 3,180 square feet is needed for native shrub installations to mitigate for tree removals at Christopher to 51" Mitigation Plan April 2010 AECOM Report Environment 4-4 Wetland D. The ratio of the planting area to impacted Wetland D forest area (approximately 1,480 square feet) is approximately 2:1. As requested by the City, mitigation for impacts to Wetland D will be fulfilled at Wetland E. A suitable mitigation area for enhancement plantings at wetland E has been identified, as shown in Figure 4-1. This area is located along Mill Creek, is highly degraded by reed canarygrass, and has been selected by PSE because it will not interfere with future projects at the Christopher Substation site. Compensatory mitigation for impacts to Wetland D will include installation of native shrub species on 3,180 square feet of PEM habitat within the identified mitigation area at Wetland E. Wetland E Mitigation. At wetland E, the proposed mitigation approach is to install all native shrubs within the mitigation area (shown in Figure 4-1 and described under Wetland D in the preceding paragraph). This approach has been selected because the forested wetlands to be impacted are comprised of scattered clumps of trees, without an intact canopy in many areas, as evidenced by the need to remove only 37 trees from this area. It is estimated that canopy cover in the forested wetlands accounts for only 20 percent of the total mapped forested wetland habitat within the project area, or approximately 4,400 square feet. Reed canarygrass is the dominant species in the openings between clumps of trees. Rather than plant native shrubs in the areas from which trees will be removed, the proposed approach is to maximize shrub plantings within PEM habitats in the mitigation area along Mill Creek. This approach will allow for a greater concentration and diversity of native shrubs in one area, and presumably increased success at shading out reed canarygrass. The total mitigation planting area within Wetland E, based on recommended native shrub installations to mitigate for project-related impacts at Wetlands D and E, is approximately 7,700 square feet. This total includes the 800 square feet to mitigate for impacts associated with wetland fill, 3,180 square feet for mitigation plantings to compensate for impacts to Wetland D, and 3,700 square feet for mitigation plantings to compensate for impacts to Wetland E. Therefore, mitigation plantings will occur in 7,700 square feet of suitable emergent habitat along Mill Creek in the mitigation area in Figure 4-1. 4.3.3 Specifications for Native Shrub Installation Specifications for recommended numbers and species of native shrub to be installed within the site's project areas are provided in Table 4-3. Plant material will be obtained, when possible, from local native plant nurseries growing stock from the local region. If the indicated species is not available, a qualified biologist/wetlands specialist will approve substitutions. The preferred period for container native plant stock installations is in the late spring or fall. However, if bare-root plant stock is used, it will be installed between December 15 and February 15. The minimum height of bare-root plants will be 18 inches at the time of installation. Installation of native plants within the mitigation areas will be conducted under the supervision of a qualified biologist with experience in wetland mitigation and native plant installations. Prior to planting, the native plant stock will be inspected to ensure that it is healthy and the specified size and species requirements are met. Where applicable, plants will be installed in groupings of three to five plants of the same species. The prescribed spacings for native vegetation installations are based on those typically required for restoration projects: 10 feet on center for taller shrubs and 5 feet on center for lower height woody stemmed ground cover plants. In the forested portions of the mitigation planting areas, shrubs will be installed within gaps of the vegetation from which trees were removed, rather than in locations based on on-center spacings. It is estimated that approximately one-third of the specified Wetland C plantings will occur within the altered forested portions of the wetland, and that the remaining two-thirds of the plants will be installed within the wetland's PEM and PSS enhancement areas.

Non-native and invasive plant species should be discouraged from overtaking the installed plant stock. Regular maintenance, including removal of non-native species by mechanical means, such as weedwhacking, hand-pulling or cutting, will be required within the planting areas. Christopher to 51s' Mitigation Plan April 2010 AECOM Report Environment 4-6 Over the long-term, vegetation within the overhead transmission line corridor will be maintained at a maximum height of 25 feet. Any necessary trimming of vegetation to meet height restrictions will be accomplished in manner that minimizes disturbance to existing native shrub habitats. The use of herbicides and/or fertilizers within the mitigation planting areas will not be permitted unless approved as a contingency plan measure. 4.5 As-built and Monitoring Schedule An as-built/first year monitoring report will be completed by a qualified biologist/wetlands specialist for submittal to the applicable regulatory agencies for use as a reference document for subsequent performance monitoring within the project site's mitigation areas. Subsequent vegetation performance monitoring will occur after the peak of growing season (July, August) and no later than October 31 in Years 2, 3, and 5 after project installation. Monitoring reports will be submitted to applicable regulatory agencies no later than December 1 st of each monitoring year. 4.6 Goals, Objectives, and Performance Standards The success of the project will be based on meeting the following objectives and performance standards: Native Vegetation Installation: • Installation of a minimum of 512 and 232 native shrubs within Wetlands C and E, respectively, as specified in the planting plan. • Installation of a minimum of 6, 14, 48 and 32, and 82 native shrubs minimum within project- associated altered Wetland A, B, C, D, and E buffer areas, respectively, as specified in the planting plan. • A minimum of five native hydrophytic woody-stemmed shrub species represented within the wetland mitigation planting areas after installation is complete. • A minimum of five native non-hydrophytic woody-stemmed shrub species representing with the wetland buffer mitigation planting areas after installation is complete. Installed Native Vegetation Survival: • In Year 1, survival of installed native shrubs within the mitigation areas will be 100 percent. If all dead plantings are replaced, the standard will be considered met. • In Years 2 and 3, survival of installed native shrubs within the mitigation areas will be 85 percent or greater. Aerial Cover: • The aerial cover of the suite of native shrub vegetation present within the forested portions of the mitigation area, will be equal to or greater than 50 and 65 percent cover in years 2 and 3, respectively. • The aerial cover of the suite of native shrub vegetation installed within the enhanced PEM and PSS wetland portions of the mitigation project areas will be equal to or greater than 5 and 15 percent in years 2 and 3, respectively. Christopher to 51s' Mitigation Plan April 2010 AECOM Report Environment 4.7 • In Year 5, aerial cover of the suite of native shrub vegetation present within the forested portions of the mitigation area will be equal to 85 percent cover or greater. In Year 5, aerial cover of the suite of native shrub vegetation present within the enhanced PEM and PSS wetland emergent portions of the mitigation area will be equal to 30 percent cover or greater. Native Plant Diversity, Habitat and Functional Ratings: • Native plant species diversity within the mitigation planting areas after the 5-year monitoring period will include a representation of at least four minimum native shrub species • PSS and upland scrub-shrub vegetation communities will be represented within wetland and wetland buffer mitigation areas, respectively, at the end of the project's five year monitoring plan. • At the end of Year 5, the project's mitigation areas are intended to serve wetland and buffer functions at moderate levels. The mitigation wetland and buffer areas will be rated according to appropriate resources and best available science and the results included in the Year 5 monitoring report. 4.6.1 Vegetation Monitoring Technique Permanent transects for vegetation monitoring at sample plots will be established within the project area. Data on the number and species of plants, survival rates, canopy (percent aerial) cover, stem density and plant heights will be measured during each monitoring period. Photo stations will be established at control points to consistently document the existing conditions during each monitoring period. 4.6.2 Contingency Measures and Plan Any fatal or diseased installed native plants observed within the planting areas will be replaced after the first growing season. A contingency mitigation plan, prepared by a qualified biologist, will be required should the mitigation project appear to be failing at rates greater than 70 percent in any monitoring year. If the percentage of cover of invasive reed canary grass exceeds 30 percent within the wetland and buffer mitigation areas, appropriate control procedures will be implemented according to a custom- designed maintenance plan for the project. If the percentage of non-native invasive and or designated noxious weeds exceeds 15 percent within the project's mitigation areas in any monitoring period, appropriate control procedures will be implemented according to a custom-designed maintenance plan for the project.

Field studies were conducted in early March and mid-April, 2008, with a short follow-up visit in mid-May. This report provides information on wetlands and streams that are likely to affect future PSE activities in the project area. 1.1 Project Background and Study Objectives Puget Sound Energy is proposing to build approximately 2 miles of new 115-kV transmission line in Auburn, Washington, from the existing Christopher Substation west to 51St Ave South. This line will be built in a right-of way (ROW) that is already fee owned or for which there is an existing easement. There will eventually be three 115-kV transmission lines in the proposed route. In order to identify critical areas that could cause impacts to construction activities or require best management practices (BMPs), ENSR conducted a wetland delineation and stream assessment along the proposed transmission line route. The survey areas, which were identified by PSE in maps and flagged in the field, are collectively referred to as the study area. The objectives of the study were to map wetlands and streams in the study area, perform a function and values assessment of wetlands, and perform an assessment of stream environmental and habitat characteristics. The information presented in the study is to be used in obtaining environmental permits necessary for the proposed transmission line project. 1.2 Regulatory Framework and Definitions The study area is located within the City of Auburn. Regulations pertaining to wetlands and streams in the study area are found in Chapter 16 of the City of Auburn Code. The Auburn Critical Areas Ordinance (CAO) is Chapter 16.10 (Critical Areas). 1.2.1 Wetlands The City of Auburn uses the definition of wetlands provided in the Washington State Wetlands Identification and Delineation Manual (Washington Department of Ecology 1997), which is as follows: "Wetland" or "wetlands" means areas that are inundated or saturated by surface water or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. Wetlands do not include those artificial wetlands intentionally created from nonwetland sites, including but not limited to irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenities. However, wetlands include those artificial wetlands intentionally created from nonwetland areas to mitigate conversion of wetlands. As stated in the CAO, the City of Auburn requires all critical areas to be "rated or classified according to their characteristics, function and value, and/or their sensitivity to disturbance." Wetlands are designated as Category I, Category II, Category III, Category IV, or artificially created, according to criteria that incorporate the Washington State Rating System for Western Washington (Washington Department of Ecology 2004). Wetland rating criteria are discussed in more detail in Section 2.2.6. The width of required wetland buffers for construction projects is based on their rating, and can range from a minimum of 25 feet to a maximum of 200 feet. Wetland Delineation and Stream Assessment 1-1 August 2008 05570-045-0400 ENSR 1.2.2 Streams The City of Auburn defines streams as follows: "Streams" means those areas where surface waters produce a defined channel or bed that demonstrates clear evidence of the passage of water and includes, but is not limited to bedrock channels, gravel beds, sand and silt beds and defined-channel swales. The channel or bed need not contain water year-round. This definition is not intended to include artificially created irrigation ditches, canals, storm or surface water devices, or other entirely artificial watercourses, unless they are used by salmonids or created for the purposes of stream mitigation. Streams are classified as Class I through Class IV, or intentionally created streams, primarily on the basis of fish habitat and other criteria. Stream rating criteria are discussed in more detail in Section 2.3. Required stream buffers are determined on the basis of stream class, and range from 25 feet to more than 100 feet. 1.3 Study Area Description The site of the proposed project is located in Township 21 North, Range 4 East, Sections 1, 2, 3, 10, 11, and 12, in the City of Auburn, Washington (Figure 1-1). The area that would be affected by the project is a long narrow corridor, beginning, at its west end, at the intersection of 51 st Avenue South and South 304th Street. The corridor runs roughly east for approximately half a mile, and then heads northeast for about a mile, past the West Valley Highway and State Route 167, ending at the Christopher Substation south of 37th Street NW. The study area included two main segments (Figure 1-1): 1) the 70-acre site of the Christopher Substation, bounded on the north by 37th Street SW, on the east by the Interurban Trail, on the south by 29th Street NW, and on the west by State Route 167; 2) the proposed project corridor from 51St Avenue South to the West Valley Highway. The area between the West Valley Highway and State Route 167 was not surveyed because the small undeveloped portion of this area was inaccessible. This area is known to support wetland habitat; however, according to PSE, the project would not impact this area and a critical area survey is therefore not required. The study area is located entirely within the Green/Duwamish River Watershed, in the Lower Green River Subwatershed. The major tributary running through the area is Mill Creek. According to the soil survey (USDA Soil Conservation Service 1973), the mean average annual precipitation for the entire study site is approximately 35 to 60 inches, and the average annual temperature is 50 degrees Fahrenheit (°F). 1.3.1 Project Corridor Much of the project corridor between 51St Avenue South and the West Valley Highway was annexed to the City of Auburn at the beginning of 2008. This portion of the study area is located near residential development to the north and south, in an area that is primarily zoned as Single-Family Residential. The corridor supports a mix of open, grassy areas and second-growth forest. Remnants of past land uses, such as abandoned buildings, overgrown gravel roads, and areas of fill, are present, indicating that the site has been disturbed to varying degrees. Roughly midway through the corridor, a stream runs north-south through the study area, and is associated with a fairly large wetland complex. The forested portion of the corridor immediately to the west of West Valley Highway is predominantly a steep hillslope. Open, grassy areas are prevalent along the corridor. Various species of grass are present, but the dominants are orchard grass (Dactylis glomerata) and bentgrass (Agrostis spp.). Meadow buttercup (Ranunculus acris) is common in moist to wet areas. The most prevalent shrub is Himalayan blackberry (Rubus armeniacus). In moist areas, forested stands of mostly red alder (Alnus rubra) occur, often with an understory of Himalayan Wetland Delineation and Stream Assessment 1 -2 August 2008 05570-045-0400 . ~ .,4 S?V$ 1 fl~tT'j" 2 S 88T1-!

The forested area in the eastern portion of the corridor has an overstory of Douglas-fir (Pseudotsuga menziesh), red alder, and bigleaf maple (Acer macrophyllum). Red elderberry (Sambucus racemosa) is prevalent in the understory. Common herbaceous species include stinging nettle (Urtica dioica), sword fern (Polystichum munitum), and Pacific waterleaf (Hydrophyllum tenuipes). Soils along most of the project corridor are mapped as Alderwood gravelly sandy loams, with slopes ranging from 0 to 30 percent. These are moderately well drained upland soils that formed in glacial deposits under conifers. They are not on the hydric soils list, but poorly drained hydric soils are found as inclusions in these map units. In the steep area at the east end of the project corridor, soils are mapped as very steep Alderwood and Kitsap soils, which are not hydric soils. The erosion hazard in this area is severe to very severe. 1.3.2 Christopher Substation Site The Christopher Substation site is bounded by paved roads/walkways on all sides. Adjacent properties are zoned to support heavy commercial and light industrial uses, with the exception of the Interurban Trail, which is open space. Mill Creek runs through the site, with two main north-south channels. The water flow at this site has apparently been altered. Along much of the western edge of the property, rip-rap is present between the stream channel and the fence line. East of the stream, there is a series of berms running most of the length of the channel. Additionally, there are narrow man-made drainage ditches along much of the property boundary (including a ditch just beyond the property boundary to the west). The substation site predominantly supports herbaceous vegetation, with reed canarygrass (Phalaris arundinacea) as the dominant species, forming a monoculture in many areas. At a few scattered areas within the stream channel, patches of cattail (Typha sp.) are present. Scrub-shrub vegetation is found along portions of the stream channel and drainage ditches, as well as between forested stands southeast of the substation. Scrub-shrub vegetation predominantly consists of Douglas spirea (Spiraea douglasn), Himalayan blackberry, and red-osier dogwood (Corpus sericea). In the north half of the site, near the substation, there are forested areas near the substation (primarily to the south and east) and along the stream channel. Dominant tree species include black cottonwood (Populus balsamifera ssp. trichocarpa) in drier areas, red alder, and willows (Salix spp.). Soils are mapped primarily as Oridia, Renton, and Norma series soils, with a small area of Puget series soils in the northwestern portion of the project area (USDA Soil Conservation Service 1973). The Oridia and Renton series are somewhat poorly drained silt loams that formed in alluvium in river valleys. The Norma series are sandy loams that occur in basins and along stream bottoms. The Puget series are poorly drained silty clay loams that formed in small depressions of river valleys. The slopes of all these series are less than 2 percent. All of these soils are found on the King County Hydric Soils List (USDA Natural Resources Conservation Service 2001). Wetland Delineation and Stream Assessment 1 -4 August 2008 05570-045-0400 ENSR 2.0 Methods 2.1 Background Review Prior to conducting field surveys, ENSR conducted a review of background materials to obtain information about potential wetland and stream locations in the study area. These materials included the following: • Soil Survey for King County Area, Washington (USDA Soil Conservation Service 1973). • City of Auburn Critical Areas maps showing wetlands and streams, based on a 2002 Auburn stream and wetland inventory. • King County GIS data (including aerial photographs and data layers of critical areas), obtained from the King County GIS Center. • National Wetland Inventory (NWI) maps (U.S. Fish and Wildlife Service 1977 to present). • Poverty Bay, Washington Quadrangle Map (U.S. Geological Survey 1994). • Auburn, Washington Quadrangle Map (U.S. Geological Survey 1973). • A previous Critical Areas Report for a portion of the study area (David Evans and Associates Inc. 2006). • Road, Grading, and Storm Drainage Plan drawings showing previously delineated wetlands in a portion of the project corridor (D.R. Strong Consulting Engineers 2007). • CAD drawings of the proposed project area, provided by PSE. 2.1.1 Wetlands The only portion of the study area for which wetlands have been mapped by the NWI and the Washington Department of Fish and Wildlife (WDFW) Priority Habitats database is the site of the Christopher Substation. City of Auburn critical areas maps indicate "existing potential wetlands" within the study area at the site of the Christopher Substation, as well as in the project corridor, just west of West Valley Highway. Because the western portion of the study area was recently annexed to Auburn, most of the project corridor is not shown on city critical areas maps. King County data layers do not identify any wetlands at all within the survey area. Previous wetland delineations have been conducted in or near portions of the study area. In 2007, wetlands in a portion of the corridor were delineated for a proposed housing development (D.R. Strong Consulting Engineers 2007). According to road, grading, and storm drainage plans showing these wetlands, three wetlands were mapped in or near the current study area. Additionally, in 2006, wetlands were delineated in the northwestern portion of the Christopher Substation site, in the immediate vicinity of the substation (David Evans and Associates Inc. 2006). This study identified two wetlands in the vicinity of the substation, but most of the site was not included in that delineation. 2.1.2 Streams City of Auburn critical areas maps depict two streams in the project area. One is Mill Creek, which has two branches that run through the Christopher Substation site. Additionally, one stream is mapped running north- south through the project corridor, west of 64th Ave South. King County GIS layers also show these two Wetland Delineation and Stream Assessment 2-1 August 2008 05570-045-0400 ENSR streams. The location of the stream in the project corridor (called "KC Stream" in the GIS attribute table) matches the Auburn critical areas map. At the Christopher substation site, however, Mill Creek is mapped splitting into two branches at the north end of the site and then returning to a single channel at the south end of the site. On the Auburn critical areas maps, the stream splits into two branches, but the east branch of the stream is "broken" by upland areas to the north and south of the substation. 2.2 Wetland Delineation and Rating As required by City regulations, the wetland delineation methodology used in this study follows Washington Department of Ecology (1997), which provides guidelines for determining whether an area should be classified as a wetland. 2.2.1 Wetland Delineation Criteria According to the manual, an area must exhibit evidence of at least one positive wetland indicator from each of the following parameters to be defined as a wetland: 1. Soils - The substrate is predominantly undrained hydric soil, or soils possess characteristics associated with reducing soil conditions. 2. Hydrology-The area is inundated either permanently or periodically at a mean water depth of less than 6.6 feet, or the soil is saturated to the surface at some time during the growing season of the prevalent vegetation. 3. Vegetation - the land supports predominantly hydrophytic vegetation (macrophytes that are able to grow in water or on a substrate that is at least periodically deficient in oxygen). The growing season is defined as the portion of the year when the soil temperature 19.7 inches below the soil surface is greater than biological zero (41 °F). This period is usually approximated by the number of frost-free days for an area (Washington Department of Ecology 1997) 2.2.2 Characteristics of Hydric Soils Hydric soils are flooded, ponded, or saturated long enough during the growing season to develop anaerobic conditions in the upper part of the soil profile (U.S. Department of Agriculture Soil Conservation Service 1991). Anaerobic conditions are created when flooding, ponding, or saturation is of sufficient duration to eliminate oxygen from the environment. These soils usually support hydrophytic vegetation. The National Technical Committee for Hydric Soils developed criteria for hydric soils and published a list of the Nation's hydric soil types (U.S. Department of Agriculture Soil Conservation Service 1991). Because they are saturated during the growing season, hydric soils usually develop certain morphological features that can be observed in the field. A prolonged anaerobic environment typically lowers the soil redox potential and causes a chemical reduction of soil components, such as iron and manganese oxides. This reduction affects solubility, movement, and aggregations of these oxides, and is often visible in the soil coloration. The duration and depth of soil saturation are used to identify hydric soils and wetlands. Soil physical features such as color are commonly used to indicate long-term soil moisture regimes. The most widely recognized colors that reflect wetness in mineral soils are low chromas (grayish) with or without high chroma (yellow/red) mottles. Subsurface horizons in hydric soils are predominately neutral gray in color and occasionally greenish or bluish. The distinctive colors result from a process known as gleization, in which prolonged saturation of mineral soil converts iron from its oxidized (ferric) form to its reduced (ferrous) state. The reduced compounds may be Wetland Delineation and Stream Assessment 2-2 August 2008 05570-045-0400 ENSR completely removed from the soil, resulting in low chromas. Mineral soils that are always saturated are uniformly gleyed throughout the saturated zone. Soils gleyed to the upper surface layer (within 12 inches of the surface) are hydric soils. Mineral soils that are alternately saturated and oxidized (aerated) during the year are usually mottled in the part of the soil that is seasonally wet. Mottles are spots or blotches of contrasting colors or shades of colors interspersed with the dominant (matrix) color. The abundance, size, and color of the mottles usually reflect the duration of the saturation period. Mineral soils that are predominately grayish with brown or yellow mottles in the upper 20 inches are usually saturated for long periods during the growing season and are commonly classified as hydric. Color chromas of two or less, using the Munsell color system, are considered low chromas and are often diagnostic of hydric soils (Munsell Color 1990). An example of a soil color that would be classified as hydric is 5YR 5/1 (the number after the slash indicates the soil's chroma). Low chroma colors include black, various shades of gray, and darker shades of brown and red. Soils that are predominately brown or yellow with few gray mottles may be saturated for shorter periods and generally are not hydric. Mineral soils that are never saturated are usually brightly colored without mottles. Two examples of soil colors that would not be classified as hydric are 5YR 5/4 and 10YR 7/3. 2.2.3 Characteristics of Wetland Hydrology Permanent or periodic inundation (in which soil is at least seasonally saturated within the rooting zone) is the hydrologic force behind wetland formation. The presence of water for 5 percent or more of the growing season typically creates an anaerobic condition in the soil, which affects the types of plants that grow and the types of soils that develop (U.S. Army Corps of Engineers 1987). Numerous factors influence the wetness of an area: precipitation, stratigraphy (i.e., layering), topography and micro relief, and soil permeability. The water found in wetlands may come from direct precipitation, overbank flooding, surface water runoff, groundwater discharge, or tidal flooding. The frequency and duration of inundation and soil saturation vary widely, and may be permanent or intermittent. The duration of inundation or saturation is usually the most important factor affecting soils and vegetation. Soil permeability, which is affected by soil texture and density, influences the duration of inundation or soil saturation. For example, soils with high clay content generally have lower permeability, absorb water more slowly, and remain saturated for a longer period of time than sandy or loamy soils. Of the three technical criteria for wetland identification, wetland hydrology is often the least exact and most difficult to characterize, primarily because of annual, seasonal, and daily fluctuations in water level. An area has wetland hydrology when saturated within the rooting zone (usually within 12 inches of the surface) for at least 5 percent of the growing season. The water table can be defined as the upper surface of groundwater, or the level below which the soil is saturated with water (U.S. Army Corps of Engineers 1987). A water table is at least 6 inches thick and persists in the soil for more than a few weeks. Field indicators used as evidence of wetland hydrology include ordinary high water marks, drift lines, drainage patterns, watermarks, sediment deposition, vegetation morphology (e.g., adventitious roots), and presence of algae or moss. 2.2.4 Characteristics of Hydrophytic Vegetation Hydrophytic vegetation is defined as macrophytic plant life growing in water or soil or on a substrate that is at least periodically deficient in oxygen as a result of excessive water content (U.S. Army Corps of Engineers 1987). A list of plants able to tolerate saturated soil conditions has been prepared by the U.S. Fish and Wildlife Service (USFWS; Reed 1988; USFWS 1993). Vascular plants are classified according to their affinity for wetland areas, and thus their probability of being found in a wetland. There are five wetland indicator status ratings, as defined below: Wetland Delineation and Stream Assessment 2-3 August 2008 05570-045-0400 ENSR • Obligate Wetland (OBL): Under natural conditions, plants occur almost exclusively in wetlands (estimated probability >99 percent). • Facultative Wetland (FACW): Plants usually occur in wetlands (estimated probability 67 to 99 percent), but are occasionally found in non-wetlands. • Facultative (FAC): Plants are equally likely to occur in wetlands and non-wetlands (estimated probability 34 to 66 percent). • Facultative Upland (FACU): Plants usually occur in non-wetlands (estimated probability 67 to 99 percent), but are occasionally found in wetlands (estimated probability 1 to 33 percent). • Obligate Upland (UPL): Plants may occur in wetlands in another region, but under natural conditions almost always occur in non-wetlands in the region specified (estimated probability >99 percent). Wetland indicator categories should not be equated to degrees of wetness. Many Obligate Wetland species occur in permanently or semipermanently flooded wetlands, but a number also occur in, or are restricted to, wetlands that are only temporarily or seasonally flooded. The actual frequency of occurrence of a species in wetlands may be anywhere within the frequency range of the indicator category. For example, a species assigned to the Facultative Upland indicator category may actually have a frequency toward the lower end of the category, while another species may have a frequency toward the upper end of the category (Reed 1988). The presence of hydrophytic vegetation is determined using the wetland indicator status of species encountered. Hydrophytic plants are those rated as FACW or wetter. Wetland boundaries are identified based on the presence of a wetland plant community, rather than any one particular indicator species. For example, a plant community with scattered individual upland species, but dominated by hydrophytic species, is considered to be a wetland community. Within each wetland, specific communities are determined on the basis of their dominant plant species, soils, and hydrology. 2.2.5 Classification Wetlands delineated in the project area are classified using the USFWS wetland hierachical classification system (Cowardin et al. 1979). This system classifies wetlands according to hydrologic, geomorphologic, chemical, and biological factors. Wetlands are first classified by the primary source of water to the wetland. These classes are usually identified by the physical form of the dominant vegetation community type or, less often, the substrate of the wetland. Only one type of primary wetland system, palustrine, is applicable to wetlands on the study site. Palustrine Systems are shallow ponds and wet areas, including all non-tidal wetlands dominated by trees, shrubs, persistent emergents, emergent mosses, or lichens. This system also includes wetlands lacking such vegetation, but with all of the following four characteristics: 1) total area is less than 8 ha (20 acres); 2) active wave-formed or bedrock shoreline features are lacking; 3) water depth in the deepest part of the basin is less than 2 m (6.6 feet) at low water; and 4) salinity, due to ocean-derived salts, is less than 0.5 parts per thousand Descriptions of other wetland systems may be found in Cowardin et al. (1979). Systems are divided into more specific categories called subsystems, although there are no subsystems within the Palustrine System. The classification system further identifies wetlands by dividing them into different classes based on general appearance of the life form in the plant community (e.g., trees, shrubs, aquatic vegetation), and subclasses based on finer differences in life form. Wetland Delineation and Stream Assessment 2-4 August 2008 05570-045-0400 ENSR Palustrine classes pertinent to the study site include Forested, Scrub-Shrub, and Emergent. These classes are defined as follows (definitions from Cowardin et al. 1979): • Forested - Characterized by woody vegetation that is 6 m (19.7 ft) or taller (abbreviated as PFO in this report). • Scrub-Shrub - Includes areas dominated by woody vegetation less than 6 m (19.7 ft) tall. The species include true shrubs, young trees, and trees or shrubs that are small or stunted because of environmental conditions (abbreviated as PSS). • Emergent - characterized by erect, rooted, herbaceous hydrophytes, excluding mosses and lichens. This vegetation is present for most of the growing season in most years. These wetlands are usually dominated by perennial plants (abbreviated as PEM). Palustrine classes normally found within the stream channel (rock bottom, unconsolidated bottom, aquatic bed, and unconsolidated shore) are classified in this report as Open Water (abbreviated as POW). 2.2.6 Wetland Rating Wetlands delineated at the study site were rated according to the criteria presented in the Auburn CAO. Numerical rating criteria follow the point-based system provided in the Washington State Wetland Rating System for Western Washington (Hruby 2004). This system scores wetlands on the basis of their sensitivity to disturbance, the functions they provide, and whether they can be replaced. Based on a series of questions about attributes of the wetland and the surrounding areas, scores pertaining to water quality functions, hydrologic functions, and habitat functions are generated. In some cases, wetlands may also be categorized on the basis of special characteristics. According to the Auburn CAO, there are five categories of wetlands, which are briefly described below: Category I Wetlands that meet any of the following criteria: a) represent a unique or rare wetland type; or b) are more sensitive to disturbance than most wetlands; or c) are relatively undisturbed and contain ecological functions that are impossible to replace within a human lifetime; or d) provide a high level of functions (scoring 70 points or more out of 100 in the Washington State Wetland Rating System for Western Washington); or e) are characterized as a national heritage wetland; or f) are characterized as a bog; or g) are over 1 acre and characterized as a mature and old-growth forested wetland. Category 11 Wetlands that are not Category I Wetlands and that meet any of the following criteria: a) provide high levels of some functions, being difficult, though not impossible to replace; or b) perform most functions relatively well (scoring 51 to 69 out of 100 points). Category I I I Wetlands that are not Category I or 11 wetlands, and that meet the following criterion: provide moderate levels of functions (scoring 30 to 50 out of 100 points). Category IV Wetlands that meet the following criterion: provide low levels of functions (scoring less than 30 out of 100 points). Artificially Created Wetlands that are purposefully created landscape features, ponds, or storm water detention or retention facilities. Artificially created wetlands do not include wetlands created as mitigation or wetlands modified for approved land use activities. Wetland Delineation and Strea m Assessment 2-5 August 2008 05570-045-0400 ENSR 2.2.7 Field Evaluation A field survey of the study area was conducted on March 1, 3, 5, and and April 17, 18, and 25, 2008, to identify, delineate, categorize, and map wetlands occurring on the study site. Additionally, a short, follow-up visit was made on May 19, 2008. Field evaluations followed methodology presented in the Washington State Wetlands Identification and Delineation Manual (Washington Department of Ecology 1997). Project Corridor. Given the narrowness of the main survey corridor, biologists walked one survey line, from the western edge to the eastern edge, using aerial photos and field markers (blue and pink flagging) to determine the boundaries of the study area. In order to ensure that the entire project area was covered, surveyors meandered along the corridor, investigating all potential wetlands and areas where the plant community type changed. Areas outside the corridor were also investigated, as allowed by accessibility, to determine whether wetlands were present adjacent to the project corridor that could potentially affected by proposed construction activities. Along the steep slope at the east end of the corridor, surveyors were restricted to walking along the blazed trail, but looked for changes in vegetation to either side of the trail that could indicate the presence of a wetland. At the base of the slope, surveyors searched the study area to look for the "existing potential wetland" mapped by the city of Auburn. Additionally, the hydrology and soils at the very base of the slope were examined to determine whether there was any seepage of groundwater that could be an indicator of wetlands on the hillslope. Since a wetland delineation was conducted in a portion of the project corridor in 2007, surveyors looked for flagging that would indicate the boundaries of previously-delineated wetlands. There was extensive white flagging in the corridor, some of which appeared to correspond to wetland boundaries, and some of which appeared to mark other things, such as property lines. Previously-delineated wetlands within the study area were re-delineated. In the case of the large wetland associated with the stream channel, we only re-delineated the portion of the wetland within the study area and extending beyond the study area boundary a distance of approximately 200 feet. Christopher Substation Site. At the Christopher substation site, two transects were run east-west across representative portions of the area, with one crossing the open area in the southern half of the property, and one crossing the forested area immediately south of the substation. In lieu of a third transect, surveyors located other sampling points based on apparent changes in plant communities and hydrology. This approach was chosen because the site has been modified from its original conditions in many areas, primarily through the deposition of fill. Selection of sampling points allowed surveyors to include altered areas that would have been missed by a third transect. For most of the site, wetland boundaries were delineated based on plant species composition, soil characteristics, and hydrological characteristics. However in areas identified by PSE as digging hazard areas (i.e., areas with a potential for having underground utilities), soils were not characterized. Boundaries of all wetlands encountered were flagged and then mapped using an 8-channel Trimble Pro XR Global Positioning System (GPS) with beacon with an accuracy of approximately 0.5 meters. Completed field data forms for wetlands delineated, as well as representative adjacent upland areas, can be found in Appendix A. Each wetland was classified using the USFWS classification system (described in Section 2.2.5) and rated using the Washington State Wetland Rating System for Western Washington (Hruby 2004) and the criteria given in the Auburn CAO. Completed wetland rating forms have been provided in Appendix B. During field surveys, biologists noted any wildlife species that were encountered, paying particular attention to native and priority species. Wetland Delineation and Stream Assessment 2-6 August 2008 05570-045-0400 ENSR 2.3 Stream Assessment 2.3.1 Stream Identification and Mapping Streams in the study area were located using a combination of King County stream GIS data, aerial photographs, and field reconnaissance. The portion of each stream within the study area was mapped on foot using GPS. In the case of Mill Creek, both banks of the stream channel were mapped at wetted width (the extent of surface water in the channel). The remaining stream channels in the project area were too narrow to map both sides of the channel within the range of accuracy of the GPS, so these streams were mapped as a single line, as close to the middle of the stream channel as possible. In the project corridor, just the portion of the stream channel within the study area was mapped in the field. This stretch of the stream was checked against the King County GIS layer to verify its accuracy. 2.3.2 Stream Characterization Important stream characteristics were recorded at a series of points along the length of each stream. Sampling points were spaced approximately 250 feet apart. For several of the small, manmade drainage ditches with little habitat diversity, sampling points were spaced at larger intervals. The following information was recorded at each stream sampling point: Stream bed type. We described the size, texture, color, and variability of sediments comprising the stream channel, as well as other materials found on the stream bed, such as organic matter. Channel profile. To the extent possible, we measured the depth of the stream across its channel to produce a rough profile. In some areas, water depth and/or dense vegetation prevented this measurement. Channel width. We estimated the width of the channel, including wetted width and bank width (the distance between the high water mark on either side of the channel. Rate and direction of flow. We rated the velocity of water in the stream at surface level as slow, moderate, or fast. We determined the approximate direction of flow. Surrounding cover. We recorded the dominant species of vegetation surrounding the stream channel and the height of the vegetation. We ranked the amount of shading of the stream as none, partial, or nearly complete. Habitat characteristics. We noted any retention structures in the stream channel, such as protruding rocks and large woody debris. We described the habitat complexity of the stream, including its sinuosity, presence of riffles and pools, channel braiding, and tributaries. Biological characteristics. We recorded the presence of fish, invertebrates, aquatic plants, and other species observed in the stream. Information for each sampling point was recorded on stream assessment data sheets, which are included in Appendix C. Additionally, photographs were taken facing upstream and downstream from each sampling point, which are included in Appendix D. 2.3.3 Stream Classification Streams located during field surveys were classified accordance with Auburn CAO regulations. There are five classes of streams, as described below. Wetland Delineation and Stream Assessment 2-7 August 2008 05570-045-0400 ENSR Class I Natural streams identified as "shorelines of the state" under the City of Auburn shoreline master program. Class 11 Natural streams that are not Class I streams and are either perennial or intermittent and have one of the following characteristics: a) contain fish habitat; or b) have significant recreational value. Class III Natural streams with perennial or intermittent flow that do not contain fish habitat. Class IV Natural streams and drainage swales with channel width less than 2 feet taken at the ordinary high water mark, that do not contain fish habitat. Intentionally Created Manmade streams, but not including streams created as mitigation. Intentionally created streams may include irrigation and drainage ditches, grass-lined swales, and canals. These streams are excluded from regulation under City of Auburn regulations, except manmade streams that provide critical habitat (designated at the federal or state level) for salmonids. Wetland Delineation and Stream Assessment 2-8 August 2008 05570-045-0400 ENSR 3.0 Results 3.1 Wetland Descriptions During field surveys, five wetlands (called wetlands A through E in this report) were delineated in the study area, as shown in Figures 3-1, 3-2, and 3-3. Wetlands A through D are located along the project corridor, and wetland E is located on the Christopher Substation Parcel. These wetlands are described in more detail in the sections that follow. During the surveys, the air temperature was typically between 40 and 60 OF, and weather ranged from clear to rainy. Although surveys began early in the year, visual observations of new vegetative growth provided evidence that the growing season had begun. However, many plant species were still in their dormant phase at the time of surveys, particularly at the Christopher Substation Site. 3.1.1 Wetland A Wetland A is a small, depressional PEM wetland, approximately 0.025 acres (1,100 square feet) in size (Figure 3-1). It is located in an open, disturbed area near the western end of the project corridor. Dominant species include orchard grass, creeping buttercup (Ranunculus repens), and common velvetgrass (Holcus lanatus). This wetland occurs at a site of possible fill deposition, as evidenced by the presence of a wooden stake deep in the soil pit. The wetland has been classified as Category IV. It has moderate water quality functions, but low hydrologic and habitat functions. Please note that although this wetland is pictured in an area with tree cover on Figure 3-1, the area has been cleared since 2002 when the photo was taken. 3.1.2 Wetland B Wetland B is a small PEM wetland, approximately 0.027 acres (1,190 square feet) in size (Figure 3-1). It is a narrow ditch, approximately 2 feet wide, with banks about 1 foot high. The ditch is oriented roughly north-south and appears to serve as a channel for surface water from upslope areas during wet periods. Dominant plant species include creeping buttercup, bentgrass, orchard grass, and stinging nettle. This wetland is located just east of a moist wooded area. It has been classified as Category IV. It has moderate water quality functions, but low hydrologic and habitat functions. 3.1.3 Wetland C Wetland C is a large PEM/PFO/PSS wetland associated with a stream channel that extends beyond the survey area to the north and south (Figure 3-3). Approximately 0.5 acres of this wetland are located within the study area, but the entire wetland is much larger, extending north and south from the study area as it follows the stream channel. This wetland was mapped and rated previously as part of a delineation for a proposed housing development (D.R. Strong Consulting Engineers 2007). The wetland boundaries shown in the drawings are similar to those delineated by ENSR, except that it was divided into two wetlands by the previous delineators. ENSR delineated a single wetland centered about the stream channel. The emergent portion is dominated by bentgrass, orchard grass, tall fescue (Schedonorus phoenix), and meadow buttercup. In the wetter portions, common rush becomes more prevalent. The forested portion of the wetland is a riparian area along the stream channel. The predominant tree species is red alder, with a Himalayan blackberry understory. The scrub-shrub portion of the wetland is dominated by Himalayan blackberry. Wetland C has been classified as a Category II wetland, primarily because it has a high potential, and the opportunity, to reduce flooding and erosion and improve water quality.

This wetland was delineated in 2007, although with slightly different boundaries. The emergent portion is dominated by orchard grass, common rush, and meadow buttercup, with small areas of reed canarygrass. The dominant tree in the forested portion is red alder, and understory dominants include Himalayan blackberry and Indian plum (Oemleria cerasiformis). Herbaceous dominants in the forested portion include meadow buttercup and large-leaved avens (Geum macrophyllum). The scrub-shrub portion consists almost entirely of Himalayan blackberry. Wetland D has been classified as a Category III wetland. It has low hydrologic functions and moderate water quality and habitat functions. 3.1.5 Wetland E Wetland E is a single large PEM/PSS/PFO riverine wetland that occupies that majority of the Christopher Substation site. Although pieces of it were mapped as separate small wetlands in a 2006 critical areas report (David Evans and Associates Inc. 2006), hydrologic connections over the entire site require it to be considered a single wetland. It appears that prior to filling portions of the area, the entire 70-acre site was a wetland. However, deposition of fill has altered the hydrology in some portions of the site enough that isolated areas no longer function as wetlands. These sites have been mapped as upland areas, as shown on Figure 3-3. It should be noted that some areas where fill has been deposited, but wetland hydrology has persisted, are currently functioning as wetlands despite their altered soils. These areas have been mapped as wetlands. Wetland E is approximately 59 acres (2,567,000 square feet) in size (with upland inclusions subtracted). The PEM component is predominant, at approximately 46.6 acres (2,028,000 square feet), followed by PFO (8.4 acres; 365,000 square feet) and PSS (4.0 acres; 173,000 square feet). Because the POW component is very small and difficult to separate out, it has been lumped with the more dominant components accordingly. Within the PEM component, reed canarygrass is nearly ubiquitous. This species forms a dense coverage of most of the wetland, and dominates many of the upland inclusions as well. In more deeply inundated areas, cattail is the dominant species. In the forested wetland portions, red alder and willows are prevalent along streams, and red alder and balsam poplar are prevalent in other areas. Where the forest is multi-layered (i.e., non-riparian areas behind the substation), red-osier dogwood is an important understory component, and creeping buttercup is predominant in the herbaceous layer. The PSS component occurs primarily along portions of the creek and drainage ditches. Dominant species are Douglas spirea and red-osier dogwood, with some Himalayan blackberry where the wetland is transitioning to upland. This wetland has been rated as a Category II wetland. It has moderate water quality functions, and high hydrologic and habitat functions. Additionally, the wetland may be subject to increased protection requirements because Mill Creek is utilized by listed salmonid species, and because the wetland contains a priority species, the great blue heron (Ardea herodias). 3.1.6 Wetlands Previously Mapped but not Delineated in the Current Study The City of Auburn has an "existing potential wetland" mapped at the eastern edge of the proposed project corridor, just west of West Valley Highway, at the base of the steep slope in this portion of the study area. Surveyors looked for signs of wetlands in this area, paying special attention to the base of the slope. A sample plot was placed at the base of the slope, and hydrology, soils, and vegetation were characterized. We found no evidence of wetlands in this area. ENSR located all of the wetlands delineated along the project corridor in 2007. One of these wetlands (labeled "Tract X on the Road, Grading, and Storm Drainage Plan; D.R. Strong Consulting Engineers 2007) is shown with a small lobe to the north of the main wetland, with a resultant buffer that comes within 75 feet of the proposed project corridor. Because it was outside of the study area, ENSR did not delineate this wetland, but Wetland Delineation and Stream Assessment 3-5 August 2008 05570-045-0400 ENSR did field-check it to make sure that it does not extend farther than depicted on the map. We confirmed that the main portion of the wetland was fairly accurately mapped. However, we did not verify the presence of the northern lobe. There was no evidence of wetland hydrology in this area, although 50% of the dominants were FAC or wetter and soils displayed borderline hydric characteristics. It is possible that the previous delineation occurred very recently after a rain and wetland hydrology appeared to be present at that time. ENSR noted a similar wet area at another location in the corridor with borderline wetland vegetation, soils, and hydrology at the time of the delineation, which was after a recent rain. After flagging and mapping the wetland, ENSR revisited the site after several consecutive dry days. On this second visit, there was no evidence of wetland hydrology. It is our opinion that these areas are not wetlands, although they may be wetter than adjacent upland areas in the surrounding landscape. The approximate location of the previously delineated wetland, with the northern lobe removed, is shown on Figure 3-2. 3.2 Stream Assessment The results of the stream assessment are summarized below for each stream identified in the study area. 3.2.1 Streams in the Project Corridor The stream labeled as "KC Stream" in King County GIS layers flows roughly to the north through the project corridor, approximately midway along the corridor (Figure 3-2). The portion of the stream channel within the study area, as field-checked by ENSR using GPS, matches well with the location of the stream in the GIS data layer provided by King County. Therefore, Figure 3-2 displays the King County data in order to show more of the stream channel than we mapped in the field. The stream varies from 1 to 4 feet in width and from 1 to 6 inches in depth within the corridor, and flow velocity in moderate. The sediment on the stream bottom is diverse in size, ranging from sand particles less than 1 millimeter in diameter to cobbles greater than 15 centimeters in diameter. The channel profile is nearly square, with steep, sharply cut banks. Surrounding vegetation includes common rush, orchard grass, and blackberry, with vegetation height ranging from 8 inches to 8 feet. The degree of stream shading is almost none in areas surrounded by grasses, but partial in areas surrounded by blackberry. The area on both sides of the stream is a wetland, and in some areas surface water can be seen flowing directly into the stream. Habitat complexity of the stream is minimal. The stream exhibits almost no sinuosity, braiding, riffles and pools, or retention structures. No fish were observed in KC stream, which is probably too shallow to support fish. According to WDFW, the creek is not utilized by fish. However, several types of m acroi nve rteb rates were found on the stream bed, and algae were observed growing on larger sediments. According to the guidance in the Auburn CAO, this stream is classified as Class III Stream. 3.2.2 Streams at the Christopher Substation Site Mill Creek. Mill Creek enters the Christopher Substation site approximately midway along the southern boundary after flowing beneath 29th Street NW (Figure 3-3). The stream splits into two branches almost immediately upon entering the site. The west branch flows west just inside the southern site boundary, then makes a 90 degree turn and flows north just inside the western site boundary. When it reaches the northern site boundary, the west branch flows through a culvert beneath 37th Street NW and out of the site. The east branch of Mill Creek flows north from the southern site boundary through the center of the site until it reaches the boundary of a forested wetland area. At this point, the stream channel becomes indistinguishable as it expands into a large area of shallow open water. The location of Mill Creek as mapped in the field corresponds well with the location mapped by the City of Auburn. According to WDFW, the portion of Mill Creek within the Christopher Substation site contains fall Chinook salmon (Oncorhyncus tshawytscha), winter steelhead (O. Wetland Delineation and Stream Assessment 3-6 August 2008 05570-045-0400 ENSR mykiss), and coho salmon (O. kisutch). Therefore, according to Auburn CAO regulations, this stream is classified as a Class II stream. West Branch - The west branch of Mill Creek is the largest stream in the study area and provides the highest quality aquatic habitat. The substrate comprising the stream bed is a fine, muddy silt with sediment particles less than 1 millimeter in diameter. The sediment ranges in color from a light brown to a dark green, but there is almost no variability in particle size or texture along the stream. In areas with deep, slow water, organic matter such as decomposing leaves and twigs has collected on the stream bottom. The wetted width of the channel is variable along its length, ranging from 4 to 22 feet at the time of the survey, with an average of about 15 feet. Bank width varies from 4 to 32 feet and averages about 20 feet. The rate of flow of the stream is slow to moderate, with barely perceptible flow in deep pool areas and faster flow with surface ripples in a few areas. The channel profile is generally rounded, although in some areas the deepest part of the channel lies to one side of the channel. Water depth in the deepest part of the channel is typically between 4 and 6 feet. Dominant vegetation species surrounding the stream include reed canarygrass, red alder, and willows, with cattail, Himalayan blackberry, and birch (Betula sp.) found less commonly. Surrounding vegetation height varies from 2 feet to 40 feet, and the degree of stream shading ranges from none to nearly complete shading. Retention structures within the stream are generally uncommon along the west branch, with infrequent, small- diameter woody debris and overhanging branches from live trees in the stream channel. There is little habitat complexity along most of the stream as a result of the previous rerouting and channelization of the stream. Riffles and pools are uncommon, and there is little braiding of the channel. In the portion of the stream near the southwest corner of the site, however, there are several pieces of large-diameter woody debris that have created deep pools and cover habitat for fish and other aquatic species. This area likely represents the best available fish habitat within the study area. No fish or other aquatic animal species were observed in the stream. Although fish are reported to occur in this area, the fine, homogenous substrate of this portion of the stream provides poor conditions for most aquatic macroinvertebrates and fish. East Branch - The east branch of Mill Creek flows north through emergent wetland habitat composed almost entirely of reed canarygrass. Along nearly the entire east branch, the substrate is a light brown, fine silt with particles less than 1 mm in diameter. A few larger cobbles are found at the extreme southern end of the east branch. Bank width varies from 10 to 30 feet, and wetted width varies from 8 to 20 feet. Flow velocity is extremely slow along the entire stream course. Water depth in the deepest part of the channel ranges from 2 feet to over 4 feet but is believed to be less than 6 feet throughout the stream. Reed canarygrass is the dominant vegetation surrounding the stream, but Douglas spirea, Himalayan blackberry, and black hawthorn (Crataegus douglasn) are also present along portions of the stream banks. Vegetation height is generally less than 3 feet. Stream shading ranges from almost none to partial shade. With the exception of some slight channel meandering and in-stream vegetation, the east branch exhibits almost no habitat complexity. No fish or other aquatic animal species were observed in the stream. Although fish are reported to occur in this area, the fine, homogeneous sediment makes it unlikely that many macroinvertebrates are found in this portion of the stream channel. Other Streams. Drainage ditches were identified within the Christopher Substation site running along the northern, eastern, and southern boundaries of the site. These ditches appear to be hydrologically connected, although the direction of flow is unclear in some areas, and they are apparently manmade. These manmade channels are classified as "Intentionally Created Streams" under the Auburn CAO, and are excluded from regulation. A ditch along the northern boundary of the site flows west into Mill Creek at the point where it flows beneath 37th Street NW. This north drainage ditch is 4 to 6 feet wide and 1 to 2 feet deep, and it appears to Wetland Delineation and Stream Assessment 3-7 August 2008 05570-045-0400 ENSR receive wetland runoff from the north end of the site. The drainage ditch along the eastern site boundary is more diverse, with open water cattail marshes at its northern and southern ends and a thicket of Himalayan blackberry and Douglas spirea in the middle. There is no perceptible direction of flow along this drainage ditch. The southern drainage ditch flows west along the site boundary until it meets the junction of the east and west branches of Mill Creek. This ditch is 2 to 4 feet wide and 2 feet deep, and is heavily clogged with aquatic vegetation resembling algae. None of the drainage ditches identified in the site provide suitable habitat for fish, nor are they mapped in King County GIS data. An additional drainage ditch was identified along the west boundary of the Christopher Substation site, west of Mill Creek, but lies just beyond the site's western property line on the far side of a wire fence. This channel was not mapped in the field. 3.3 Wildlife Observations Although a formal wildlife survey and functions and values assessment was not included in the scope of this project, biologists did note wildlife species during the course of wetland delineations and stream assessments. These observations are summarized in this section Along the proposed project corridor, ENSR biologists saw or heard the following bird species: American crow (Corvus brachyrhynchos), American robin (Turdus migratorius), Steller's jay (Cyanocitta stellen), northern flicker (Colaptes auratus), dark-eyed junco (Junco hyemalis), black-capped chickadee (Poecile atricapilla), and pileated woodpecker (Dryocopus pileatus). Most of these birds were associated with patches of forested habitat within and near the corridor. Additionally, an active red-tailed hawk (Buteo jamaicensis) nest was observed at the east of the project corridor, near the West Valley Highway. The only mammal encountered was a rabbit or hare of unknown species. Out of species encountered, only pileated woodpecker is a priority species, with breeding areas considered priority areas. Biologists did not confirm the presence of breeding areas in the project corridor; it is more likely that suitable breeding habitat would be located in the forested area to the north of the project corridor. At the Christopher Substation site, biologists noted coyote scat in numerous places along grassy roads/trails within the site. Bird and waterfowl species observed along and near Mill Creek include American bittern (Botaurus lentiginosus), black-and-white warbler (Mniotilta varia), hooded merganser (Lophodytes cucullatus), mallard (Anas platyrhynchos), marsh wren (Cistothorus palustris), and song sparrow (Melospiza melodia). Near the drainage ditch along the site's eastern boundary, biologists saw American crows, hooded mergansers, red-winged blackbirds (Agelaius phoeniceus), and brown-headed cowbirds (Molothrus ater). Bird species observed in forested areas in the north end of the site include downy woodpecker (Picoides pubescens), black-capped chickadee, American robin, and song sparrow. Marsh wren was common at the site, and was heard in many locations within emergent wetland areas dominated by reed canarygrass. Two great blue herons and a northern flicker were seen flying over the central portion of the site. An active red- tailed hawk nest was observed near the southwest corner of the substation. Of the species observed at the site, great blue heron is considered a priority species by WDFW. Breeding areas are considered priority habitats. No great blue heron nests were observed in forested areas on the site, so use of this area as breeding habitat cannot be confirmed. The observed birds could possibly be part of a large breeding colony of herons roughly 2 miles south of the site.

Additional information is provided in the sections that follow. Since almost the entire Christopher Substation site is a wetland, a figure showing wetland buffers at this site has not been included. However, mitigation requirements pertaining to the site are provided below. Figure 4-3 shows the breakdown of wetland types at the Christopher Substation site, overlain by a PSE-provided construction drawing showing the proposed alignment of the transmission line. According to this drawing, the proposed project could potentially impact emergent and forested wetland habitat. 4.1 Wetlands 4.1.1 Required Buffers According to the Auburn CAO, wetland buffers are determined based on the rating of the wetland, site conditions, site design, and intensity and operational characteristics of the development/land use. Minimum and maximum buffer widths have been established for each wetland category. Table 4-1 summarizes the minimum buffers required for the five delineated wetlands, as well as the potential maximum buffer width for each. Table 4.1 Required City of Auburn Wetland Buffers Wetland Size (acres) Category Minimum Buffer Width (ft) Maximum Buffer Width (ft) A 0.025 IV 25 30 B 0.027 IV 25 30 C - Not determined II 50 100 D F- 0.3 III 25 50 E 59 11 50 100 The need for increased buffer widths, up to the maximums listed above, is determined by the director of the City of Auburn Department of Planning and Community Development, as necessary to protect wetland functions and values. Wetland buffer width averaging, up to a 35 percent reduction in width, may be allowed, under certain conditions, if the site has less than 25 percent slopes and the reduction in width will not result in adverse effects to the wetland. Additionally, the buffer width may be reduced by up to 35 percent if the applicant restores or enhances the buffer by such means as planting native trees or shrubs and replacing exotic species with native species. 4.1.2 Mitigation Ratios The City of Auburn permits some wetland alterations, provided the applicant enhances or creates areas of wetlands to compensate for wetland losses. This required compensation is determined based on acreage, function, type, location, timing factors, and projected success of enhancement or creation. Table 4-2 summarizes the required acreage replacement and enhancement ratios for Category II, III, and IV wetlands. Wetland Delineation and Stream Assessment 4-1 August 2008 05570-045-0400 ENSR Table 4-2. Wetland Replacement and Enhancement Ratios Wetland Category Wetland Creation Ratio (Acres) Wetland Enhancement Ratio (Acres) Acres Created or Enhanced: Acres Impacted) Category II Forested 3:1 6:1 Scrub-shrub 2:1 4:1 Emergent 2:1 4:1 Category I I I Forested 3:1 6:1 Scrub-shrub 2:1 4:1 Emergent 2:1 4:1 Category IV 1.25:1 2.5:1 Category IV wetlands can be mitigated by either meeting one of these replacement ratios or implementing mitigation that ensures no net loss of values and functions of the larger ecosystem in which the critical area is located. 4.1.3 Streams According to the Auburn CAO, required stream buffer widths (measured from the ordinary high water mark) are determined based on the class of the stream. Minimum buffer widths for the streams in the study area are summarized in Table 4-3 below. Table 4-3. Required City of Auburn Stream Buffers Stream Stream Class Minimum Buffer Width "KC Stream" III 25 feet Mill Creek II 75 feet Drainage Ditches Intentional) Created Not regulated These buffer widths may be increased by a maximum of 50 percent for all classes of regulated streams except Class III streams, for which buffer widths may be increased by up to 100 percent, based on site-specific conditions and the functions and values of the stream. Enhancement measures such as removal of fish barriers, enhancement of fish and wildlife habitat, and other mitigating measures may be proposed that will be considered in establishing buffer requirements. Buffer widths may also be reduced on a case-by-case basis, by up to 35 percent, provided that the reduction will not result in any adverse impact to the stream. Given that listed salmonid species are reported to occur in Mill Creek on the Christopher Substation site, required buffers could potentially be greater than the minimum required buffers in order to protect fish habitat. Buffer width averaging may be allowed for Class II and III streams, provided enhancement measures are implemented, the total buffer area does not decrease, stream functions and values will not decrease, and the buffer width is not reduced by more than 35 percent in any location.

Minimum required buffers for these critical areas range from 25 to 50 feet. East of State Route 167, the entire parcel where the Christopher Substation is sited, with the exception of manmade upland inclusions, is a wetland complex. In this area, wetlands cannot be avoided, and PSE must consider mitigation if the proposed project requires fill or alteration of wetland habitat. Additionally, Mill Creek requires a minimum buffer of 75 feet, which could very likely be increased to 100 feet because the stream is known to support listed salmonids.

Has the wetland unit been documented as a habitat for any Federally listed Threatened or Endangered animal or plant species (TIE species)? For the purposes of this rating system, "documented" means the wetland is on the appropriate state or federal database. SP2. Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. Note: Wetlands with State listed plant species are categorized as Category I Natural Heritage Wetlands see . 19 of data form). SPI Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? SP4. Does the wetland unit have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the ydrozeomorphic Class of the wetland being rated The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands.

NO - go to 2 YES - the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES - Freshwater Tidal Fringe NO - Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO - go to 3 YES - The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m)? NO - go to 4 YES - The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3ft diameter and less than 1 foot deep). NO - go to 5 YES - The wetland class is Slope Wetland Rating Form - western Washington 3 August 2004 version 2 Wetland name or number 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding. NO - go to 6 YES - The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. -Slope + Riverine Riverine Slope + De ressional De ressional Slope + Lake-fringe Lake-fringe Depressional + Riverine along stream within boundary Depressional De ressional + Lake-fringe De ressional Salt Water Tidal Fringe and any other class of freshwater Treat as ESTUARINE under wetland wetlands with special characteristics If you are unable still to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

NOTE: the connections do not have to be relatively undisturbed. These are DFW definitions. Check with your local DFW biologist if there are any questions. Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres). Cliffs: Greater than 7.6 m (25 ft) high and occurring below 5000 ft. Old-growth forests: (Old-growth west of Cascade crest) Stands of at least 2 tree species, forming a multi-layered canopy with occasional small openings; with at least 20 trees/ha (8 trees/acre) > 81 cm (32 in) dbh or > 200 years of age. Mature forests: Stands with average diameters exceeding 53 cm (21 in) dbh; crown cover may be less that 100%; crown cover may be less that 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally less than that found in old- growth; 80 - 200 years old west of the Cascade crest. Prairies: Relatively undisturbed areas (as indicated by-dominance of native plants) where grasses and/or forbs form the natural climax plant community. Talus: Homogenous areas of rock rubble ranging in average size 0.15 - 2.0 m (0.5 - 6.5 ft), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. Caves: A naturally occurring cavity, recess, void, or system of interconnected passages Oregon white Oak: Woodlands Stands of pure oak or oak/conifer associations where canopy coverage of the oak component of the stand is 25%. Urban Natural Open Space: A priority species resides within or is adjacent to the open space and uses it for breeding and/or regular feeding; and/or the open space functions as a corridor connecting other priority habitats, especially those that would otherwise be isolated; and/or the open space is an isolated remnant of natural habitat larger than 4 ha (10 acres) and is surrounded by urban development. Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi- enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean-derived salts measure less than 0.5ppt. during the period of average annual low flow. Includes both estuaries and lagoons. Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs, snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion control).

Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? SP4. Does the wetland unit have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hydro eomorphic Class of the wetland bein rated.. The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Rating Form - western Washington 2 August 2004 version 2 Wetland name or number Classification of Wetland Units in Western Washington If the hydrologic crrterta listed m each guestiQp do not apply to the entire unit bein g rated, you.probably. have a unit with multiple HGM classes. In-this. case; identify which r hydrol c criteria in questions 1-7 apply;tapdgo to Questiott 8. 1. Are the water levels in the entire unit usually controlled by tides (i.e. except during floods)? NO - go to 2 YES - the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES - Freshwater Tidal Fringe NO - Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO -go to 3 YES - The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m)? NO - go to 4 YES - The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3ft diameter and less than I foot deep). NO - go to 5 YES - The wetland class is Slope Wetland Rating Form - western Washington 3 August 2004 version 2 Wetland name or number 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding. NO - go to 6 YES - The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO -go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to cla"ssify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. W11 VIA" 1NM_v. _ n; 'n 14i. 1 9I.

NOTE: the connections do not have to be relatively undisturbed. These are DFW definitions. Check with your local DFW biologist if there are any questions. Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres). Cliffs: Greater than 7.6 m (25 ft) high and occurring below 5000 ft. Old-growth forests: (Old-growth west of Cascade crest) Stands of at least 2 tree species, forming a multi-layered canopy with occasional small openings; with at least 20 trees/ha (8 trees/acre) > 81 cm (32 in) dbh or > 200 years of age. Mature forests: Stands with average diameters exceeding 53 cm (21 in) dbh; crown cover may be less that 100%; crown cover may be less that 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally less than that found in old- growth; 80 - 200 years old west of the Cascade crest. Prairies: Relatively undisturbed areas (as indicated by dominance of native plants) where grasses and/or forbs form the natural climax plant community. Talus: Homogenous areas of rock rubble ranging in average size 0.15 - 2.0 m (0.5 - 6.5 ft), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. Caves: A naturally occurring cavity, recess, void, or system of interconnected passages Oregon white Oak: Woodlands Stands of pure oak or oak/conifer associations where canopy coverage of the oak component of the stand is 25%. V Urban Natural Open Space: A priority species resides within or is adjacent to the open space and uses it for breeding and/or regular feeding; and/or the open space functions as a I corridor connecting other priority habitats, especially those that would otherwise be ` isolated; and/or the open space is an isolated remnant of natural habitat larger than 4 ha (10 acres) and is surrounded by urban development. Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi- enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean-derived salts measure less than 0.5ppt. during the period of average annual low flow. Includes both estuaries and lagoons. Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs, snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion control).

Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. Note: Wetlands with State listed plant species are categorized as Category I Natural Heritage Wetlands see . 19 of data form). SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? SP4. Does the wetland unit have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hydro eomorphic Class of the wetland being rated. The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Rating Form - western Washington 2 August 2004 version 2 Wetland name or number Classification of.Wetland Units in Western Washington If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES - Freshwater Tidal Fringe NO - Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO - go to 3 YES - The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m)? NO - go to 4 YES - The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the ent' a wetland unit meet all of the following criteria? e wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without istinct banks. The water leaves the wetland without being impounded?

Does the, entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding. NO - go to 6 _-Y9S -`The wetland class is e 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, ifpresent, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO -go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. ~Y Slope + Riverine r"g -n g AM INS mail" iverine Slope + De ressional ss-iorial Slope + Lake-fringe Lake-fringe Depressional + Riverine along stream within boundary Depressional De ressional + Lake-fringe Depressional Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE under wetlands with special characteristics If you are unable still to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

NOTE: the con ections do not have to be relatively undisturbed. T se are DFW definitions. Check with your local DFW biologist if there are any questions. Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres). Cliffs: Greater than 7.6 m (25 ft) high and occurring below 5000 ft. Old-growth forests: (Old-growth west of Cascade crest) Stands of at least 2 tree species, forming a multi-layered canopy with occasional small openings; with at least 20 trees/ha (8 trees/acre) > 81 cm (32 in) dbh or > 200 years of age. Mature forests: Stands with average diameters exceeding 53 cm (21 in) dbh; crown cover may be less that 100%; crown cover may be less that 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally less than that found in old- growth; 80 - 200 years old west of the Cascade crest. Prairies: Relatively undisturbed areas (as indicated by dominance of native plants) where grasses and/or forbs form the natural climax plant community. Talus: Homogenous areas of rock rubble ranging in average size 0.15 - 2.0 m (0.5 - 6.5 ft), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. Caves: A naturally occurring cavity, recess, void, or system of interconnected passages Oregon white Oak: Woodlands Stands of pure oak or oak/conifer associations where canopy coverage of the oak component of the stand is 25%.

Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi- enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean-derived salts measure less than 0.5ppt. during the period of average annual low flow. Includes both estuaries and lagoons. Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs, snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion control).

Has the wetland unit been documented as a habitat for any Federally listed Threatened or Endangered animal or plant species (TIE species)? For the purposes of this rating system, "documented" means the wetland is on the appropriate state or federal database. SP2. Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, "documented" means the-wetland is on the appropriate state database. Note: Wetlands with State listed plant species are categorized as Category I Natural Heritage Wetlands see . 19 of data form). SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? ' SP4. Does the wetland unit have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hydro eomorphic Class of the wetland being rated. The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Rating Form - western Washington 2 August 2004 version 2 Wetland name or number Classification of,Wetland Units in Western Washington If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES - Freshwater Tidal Fringe NO - Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO - go to 3 YES - The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m)? NO - go to 4 YES - The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3ft diameter and less than 1 foot deep). NO - go to 5 YES - The wetland class is Slope Wetland Rating Form - western Washington 3 August 2004 version 2 1. Are the water levels in the entire unit usually controlled by tides (i.e. except during floods)? NO - go to 2 , YES - the wetland class is Tidal Fringe Wetland name or number 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE. The riverine unit can contain depressions that are filled with water when the river is not flooding. NO - go to 6 YES - The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO -go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. Slope + Riverine Riverine Slope + De ressional De ressional Slope + Lake-fringe Lake-fringe Depressional + Riverine along stream within boundary Depressional De ressional + Lake-fringe Depressional Salt Water Tidal Fringe and any other class of freshwater Treat as ESTUARINE under wetland wetlands with special characteristics If you are unable still to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hydro eg omorphic Class of the wetland being rated The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below.

Are the water levels in the entire unit usually controlled by tides (i.e. except during floods)? QNO go to 2 YES - the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES - Freshwater Tidal Fringe NO - Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO go to 3 YES - The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m)? N '-go to 4 YES - The wetland class is Lake-fringe (Lacustrine Fringe) 4. oes the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3ft diameter and less than 1 foot deep). NO - go to 5 YES - The wetland class is Slope Wetland Rating Form - western Washington 3 August 2004 version 2 Wetland name or number 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding. NO - go to 6 YES The wetland class i Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the r . of the wetland. N; - go to 7 YES - The wetland class is Depressional Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. d- go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. N ..M.m II~J YY',.

If you answer yes you will still need to rate the wetland based on its functions. - Old-growth forests: (west of Cascade crest) Stands of at least two tree species, forming a multi-layered canopy with occasional small openings; with at least 8 trees/acre (20 trees/hectare) that are at least 200 years of age OR have a diameter at breast height (dbh) of 32 inches (81 cm) or more. NOTE: The criterion for dbh is based on measurements for upland forests. Two-hundred year old trees in wetlands will often have a smaller dbh because their growth rates are often slower. The DFW criterion is and "OR" so old-growth forests do not necessarily have to have trees of this diameter. - Mature forests: (west of the Cascade Crest) Stands where the largest trees are 80 - 200 years old OR have average diameters (dbh) exceeding 21 inches (53cm); crown cover may be less that 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally less than that found in old-growth.

Field studies were conducted in early March and mid-April, 2008, with a short follow-up visit in mid-May. This report provides information on wetlands and streams that are likely to affect future PSE activities in the project area. 1.1 Project Background and Study Objectives Puget Sound Energy is proposing to build approximately 2 miles of new 115-kV transmission line in Auburn, Washington, from the existing Christopher Substation west to 51St Ave South. This line will be built in aright-of way (ROW} that is already fee owned or for which there is an existing easement. There will eventually be three 115-kV transmission lines in the proposed route. In order to identify critical areas that could cause impacts to construction activities or require best management practices (BMPs}, ENSR conducted a wetland delineation and stream assessment along the proposed transmission line route. The survey areas, which were identified by PSE in maps and flagged in the field, are collectively referred to as the study area. The objectives of the study were to map wetlands and streams in the study area, perform a function and values assessment of wetlands, and perform an assessment of stream environmental and habitat characteristics. The information presented in the study is to be used in obtaining environmental permits necessary for the proposed transmission line project. 1.2 Regulatory Framework and Definitions The study area is located within the City of Auburn. Regulations pertaining to wetlands and streams in the study area are found in Chapter 16 of the City of Auburn Code. The Auburn Critical Areas Ordinance (CAO} is Chapter 16.10 (Critical Areas}. 1.2.1 Wetlands The City of Auburn uses the definition of wetlands provided in the Washington State Wetlands Identification and Delineation Manual (Washington Department of Ecology 1997}, which is as follows: "Wetland" or "wetlands" means areas that are inundated or saturated by surface water or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. Wetlands do not include those artificial wetlands intentionally created from nonwetland sites, including but not limited to irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenities. However, wetlands include those artificial wetlands intentionally created from nonwetland areas to mitigate conversion of wetlands. As stated in the CAO, the City of Auburn requires all critical areas to be "rated or classified according to their characteristics, function and value, and/or their sensitivity to disturbance." Wetlands are designated as Category I, Category II, Category III, Category IV, or artificially created, according to criteria that incorporate the Washington State Rating System for Western Washington (Washington Department of Ecology 2004}. Wetland rating criteria are discussed in more detail in Section 2.2.6. The width of required wetland buffers for construction projects is based on their rating, and can range from a minimum of 25 feet to a maximum of 200 feet. Wetland Delineation and Stream Assessment 1-1 August 2008 05570-045-0400 EI~SR 1.2.2 Streams The City of Auburn defines streams as follows: "Streams" means those areas where surface waters produce a defined channel or bed that demonstrates clear evidence of the passage of water and includes, but is not limited to bedrock channels, gravel beds, sand and silt beds and defined-channel swales. The channel or bed need not contain water year-round. This definition is not intended to include artificially created irrigation ditches, canals, storm or surface water devices, or other entirely artificial watercourses, unless they are used by salmonids or created for the purposes of stream mitigation. Streams are classified as Class I through Class IV, or intentionally created streams, primarily on the basis of fish habitat and other criteria. Stream rating criteria are discussed in more detail in Section 2.3. Required stream buffers are determined on the basis of stream class, and range from 25 feet to more than 100 feet. 1.3 Study Area Description The site of the proposed project is located in Township 21 North, Range 4 East, Sections 1, 2, 3,10,11, and 12, in the City of Auburn, Washington (Figure 1-1 }.The area that would be affected by the project is a long narrow corridor, beginning, at its west end, at the intersection of 51St Avenue South and South 304t" Street. The corridor runs roughly east for approximately half a mile, and then heads northeast for about a mile, past the West Valley Highway and State Route 167, ending at the Christopher Substation south of 37t" Street NW. The study area included two main segments (Figure 1-1 }:1 }the 70-acre site of the Christopher Substation, bounded on the north by 37t" Street SW, on the east by the Interurban Trail, on the south by 29t" Street NW, and on the west by State Route 167; 2}the proposed project corridor from 51St Avenue South to the West Valley Highway. The area between the West Valley Highway and State Route 167 was not surveyed because the small undeveloped portion of this area was inaccessible. This area is known to support wetland habitat; however, according to PSE, the project would not impact this area and a critical area survey is therefore not required. The study area is located entirely within the Green/Duwamish River Watershed, in the Lower Green River Subwatershed. The major tributary running through the area is Mill Creek. According to the soil survey (USDA Soil Conservation Service 1973},the mean average annual precipitation for the entire study site is approximately 35 to 60 inches, and the average annual temperature is 50 degrees Fahrenheit (°F}. 1.3.1 Project Corridor Much of the project corridor between 51St Avenue South and the West Valley Highway was annexed to the City of Auburn at the beginning of 2008. This portion of the study area is located near residential development to the north and south, in an area that is primarily zoned asSingle-Family Residential. The corridor supports a mix of open, grassy areas and second-growth forest. Remnants of past land uses, such as abandoned buildings, overgrown gravel roads, and areas of fill, are present, indicating that the site has been disturbed to varying degrees. Roughly midway through the corridor, a stream runs north-south through the study area, and is associated with a fairly large wetland complex. The forested portion of the corridor immediately to the west of West Valley Highway is predominantly a steep hillslope. Open, grassy areas are prevalent along the corridor. Various species of grass are present, but the dominants are orchard grass (Dactylis glomerata} and bentgrass (Agrostis spp.}. Meadow buttercup (Ranunculus acris) is common in moist to wet areas. The most prevalent shrub is Himalayan blackberry (Rubus armeniacus}. In moist areas, forested stands of mostly red alder (Alnus rubra} occur, often with an understory of Himalayan Wetland Delineation and Stream Assessment 1-2 August 2008 05570-045-0400 . ~ ~ ~ r • ~ a ~ r, ~S 28$Tt=1 ST -1 'i!-~►+~yt~'M . t'~4fiF i S 2887H pL r S 289 FJ -PL i - s - 1 .

The forested area in the eastern portion of the corridor has an overstory of Douglas-fir (Pseudotsuga menziesii}, red alder, and bigleaf maple (Acer macrophyllum}. Red elderberry (Sambucus racemosa} is prevalent in the understory. Common herbaceous species include stinging nettle (Urtica dioica), sword fern (Polystichum munitum}, and Pacific waterleaf (Hydrophyllum tenuipes). Soils along most of the project corridor are mapped as Alderwood gravelly sandy loams, with slopes ranging from 0 to 30 percent. These are moderately well drained upland soils that formed in glacial deposits under conifers. They are not on the hydric soils list, but poorly drained hydric soils are found as inclusions in these map units. In the steep area at the east end of the project corridor, soils are mapped as very steep Alderwood and Kitsap soils, which are not hydric soils. The erosion hazard in this area is severe to very severe. 1.3.2 Christopher Substation Site The Christopher Substation site is bounded by paved roads/walkways on all sides. Adjacent properties are zoned to support heavy commercial and light industrial uses, with the exception of the Interurban Trail, which is open space. Mill Creek runs through the site, with two main north-south channels. The water flow at this site has apparently been altered. Along much of the western edge of the property, rip-rap is present between the stream channel and the fence line. East of the stream, there is a series of berms running most of the length of the channel. Additionally, there are narrow man-made drainage ditches along much of the property boundary (including a ditch just beyond the property boundary to the west}. The substation site predominantly supports herbaceous vegetation, with reed canarygrass (Phalaris arundinacea} as the dominant species, forming a monoculture in many areas. At a few scattered areas within the stream channel, patches of cattail (Typha sp.) are present. Scrub-shrub vegetation is found along portions of the stream channel and drainage ditches, as well as between forested stands southeast of the substation. Scrub-shrub vegetation predominantly consists of Douglas spirea (Spiraea douglasi~), Himalayan blackberry, and red-osier dogwood (Cornus sericea). In the north half of the site, near the substation, there are forested areas near the substation (primarily to the south and east} and along the stream channel. Dominant tree species include black cottonwood (Populus balsamifera ssp. trichocarpa} in drier areas, red alder, and willows (Salix spp.}. Soils are mapped primarily as Oridia, Renton, and Norma series soils, with a small area of Puget series soils in the northwestern portion of the project area (USDA Soil Conservation Service 1973}. The Oridia and Renton series are somewhat poorly drained silt loams that formed in alluvium in river valleys. The Norma series are sandy loams that occur in basins and along stream bottoms. The Puget series are poorly drained silty clay loams that formed in small depressions of river valleys. The slopes of all these series are less than 2 percent. All of these soils are found on the King County Hydric Soils List (USDA Natural Resources Conservation Service 2001 Wetland Delineation and Stream Assessment 1-4 August 2008 05570-045-0400 EI~SR 2.0 Methods 2.1 Background Review Prior to conducting field surveys, ENSR conducted a review of background materials to obtain information about potential wetland and stream locations in the study area. These materials included the following: • Soil Survey for King County Area, Washington (USDA Soil Conservation Service 1973}. • City of Auburn Critical Areas maps showing wetlands and streams, based on a 2002 Auburn stream and wetland inventory. • King County GIS data (including aerial photographs and data layers of critical areas), obtained from the King County GIS Center. • National Wetland Inventory (NWI} maps (U.S. Fish and Wildlife Service 1977 to present}. • Poverty Bay, Washington Quadrangle Map (U.S. Geological Survey 1994}. • Auburn, Washington Quadrangle Map (U.S. Geological Survey 1973}. • A previous Critical Areas Report for a portion of the study area (David Evans and Associates Inc. 2006}. • Road, Grading, and Storm Drainage Plan drawings showing previously delineated wetlands in a portion of the project corridor (D.R. Strong Consulting Engineers 2007}. • CAD drawings of the proposed project area, provided by PSE. 2.1.1 Wetlands The only portion of the study area for which wetlands have been mapped by the NWI and the Washington Department of Fish and Wildlife (WDFW} Priority Habitats database is the site of the Christopher Substation. City of Auburn critical areas maps indicate "existing potential wetlands" within the study area at the site of the Christopher Substation, as well as in the project corridor, just west of West Valley Highway. Because the western portion of the study area was recently annexed to Auburn, most of the project corridor is not shown on city critical areas maps. King County data layers do not identify any wetlands at all within the survey area. Previous wetland delineations have been conducted in or near portions of the study area. In 2007, wetlands in a portion of the corridor were delineated for a proposed housing development (D.R. Strong Consulting Engineers 2007}. According to road, grading, and storm drainage plans showing these wetlands, three wetlands were mapped in or near the current study area. Additionally, in 2006, wetlands were delineated in the northwestern portion of the Christopher Substation site, in the immediate vicinity of the substation (David Evans and Associates Inc. 2006). This study identified two wetlands in the vicinity of the substation, but most of the site was not included in that delineation. 2.1.2 Streams City of Auburn critical areas maps depict two streams in the project area. One is Mill Creek, which has two branches that run through the Christopher Substation site. Additionally, one stream is mapped running north- souththrough the project corridor, west of 64th Ave South. King County GIS layers also show these two Wetland Delineation and Stream Assessment 2-1 August 2008 05570-045-0400 EI~SR streams. The location of the stream in the project corridor (called "KC Stream" in the GIS attribute table) matches the Auburn critical areas map. At the Christopher substation site, however, Mill Creek is mapped splitting into two branches at the north end of the site and then returning to a single channel at the south end of the site. On the Auburn critical areas maps, the stream splits into two branches, but the east branch of the stream is "broken" by upland areas to the north and south of the substation. 2.2 Wetland Delineation and Rating As required by City regulations, the wetland delineation methodology used in this study follows Washington Department of Ecology (1997}, which provides guidelines for determining whether an area should be classified as a wetland. 2.2.1 Wetland Delineation Criteria According to the manual, an area must exhibit evidence of at least one positive wetland indicator from each of the following parameters to be defined as a wetland: 1. Soils -The substrate is predominantly undrained hydric soil, or soils possess characteristics associated with reducing soil conditions. 2. Hydrology- The area is inundated either permanently or periodically at a mean water depth of less than 6.6 feet, or the soil is saturated to the surface at some time during the growing season of the prevalent vegetation. 3. Vegetation -the land supports predominantly hydrophytic vegetation (macrophytes that are able to grow in water or on a substrate that is at least periodically deficient in oxygen}. The growing season is defined as the portion of the year when the soil temperature 19.7 inches below the soil surface is greater than biological zero (41 °F). This period is usually approximated by the number offrost-free days for an area (Washington Department of Ecology 1997} 2.2.2 Characteristics of Hydric Soils Hydric soils are flooded, ponded, or saturated long enough during the growing season to develop anaerobic conditions in the upper part of the soil profile (U.S. Department of Agriculture Soil Conservation Service 1991 Anaerobic conditions are created when flooding, ponding, or saturation is of sufficient duration to eliminate oxygen from the environment. These soils usually support hydrophytic vegetation. The National Technical Committee for Hydric Soils developed criteria for hydric soils and published a list of the Nation's hydric soil types (U.S. Department of Agriculture Soil Conservation Service 1991 Because they are saturated during the growing season, hydric soils usually develop certain morphological features that can be observed in the field. A prolonged anaerobic environment typically lowers the soil redox potential and causes a chemical reduction of soil components, such as iron and manganese oxides. This reduction affects solubility, movement, and aggregations of these oxides, and is often visible in the soil coloration. The duration and depth of soil saturation are used to identify hydric soils and wetlands. Soil physical features such as color are commonly used to indicate long-term soil moisture regimes. The most widely recognized colors that reflect wetness in mineral soils are low chromas (grayish} with or without high chroma (yellow/red} mottles. Subsurface horizons in hydric soils are predominately neutral gray in color and occasionally greenish or bluish. The distinctive colors result from a process known as gleization, in which prolonged saturation of mineral soil converts iron from its oxidized (ferric} form to its reduced (ferrous} state. The reduced compounds may be Wetland Delineation and Stream Assessment 2-2 August 2008 05570-045-0400 EI~SR completely removed from the soil, resulting in low chromas. Mineral soils that are always saturated are uniformly gleyed throughout the saturated zone. Soils gleyed to the upper surface layer (within 12 inches of the surface} are hydric soils. Mineral soils that are alternately saturated and oxidized (aerated) during the year are usually mottled in the part of the soil that is seasonally wet. Mottles are spots or blotches of contrasting colors or shades of colors interspersed with the dominant (matrix} color. The abundance, size, and color of the mottles usually reflect the duration of the saturation period. Mineral soils that are predominately grayish with brown or yellow mottles in the upper 20 inches are usually saturated for long periods during the growing season and are commonly classified as hydric. Color chromas of two or less, using the Munsell color system, are considered low chromas and are often diagnostic of hydric soils (Munsell Color 1990). An example of a soil color that would be classified as hydric is 5YR 511 (the number after the slash indicates the soil's chroma}. Low chroma colors include black, various shades of gray, and darker shades of brown and red. Soils that are predominately brown or yellow with few gray mottles may be saturated for shorter periods and generally are not hydric. Mineral soils that are never saturated are usually brightly colored without mottles. Two examples of soil colors that would not be classified as hydric are 5YR 5/4 and 10YR 7/3. 2.2.3 Characteristics of Wetland Hydrology Permanent or periodic inundation (in which soil is at least seasonally saturated within the rooting zone) is the hydrologic force behind wetland formation. The presence of water for 5 percent or more of the growing season typically creates an anaerobic condition in the soil, which affects the types of plants that grow and the types of soils that develop (U.S. Army Corps of Engineers 1987}. Numerous factors influence the wetness of an area: precipitation, stratigraphy (i.e., layering},topography and micro relief, and soil permeability. The water found in wetlands may come from direct precipitation, overbank flooding, surface water runoff, groundwater discharge, or tidal flooding. The frequency and duration of inundation and soil saturation vary widely, and maybe permanent or intermittent. The duration of inundation or saturation is usually the most important factor affecting soils and vegetation. Soil permeability, which is affected by soil texture and density, influences the duration of inundation or soil saturation. For example, soils with high clay content generally have lower permeability, absorb water more slowly, and remain saturated for a longer period of time than sandy or loamy soils. Of the three technical criteria for wetland identification, wetland hydrology is often the least exact and most difficult to characterize, primarily because of annual, seasonal, and daily fluctuations in water level. An area has wetland hydrology when saturated within the rooting zone (usually within 12 inches of the surface) for at least 5 percent of the growing season. The water table can be defined as the upper surface of groundwater, or the level below which the soil is saturated with water (U.S. Army Corps of Engineers 1987}. A water table is at least 6 inches thick and persists in the soil for more than a few weeks. Field indicators used as evidence of wetland hydrology include ordinary high water marks, drift lines, drainage patterns, watermarks, sediment deposition, vegetation morphology (e.g., adventitious roots}, and presence of algae or moss. 2.2.4 Characteristics of Hydrophytic Vegetation Hydrophytic vegetation is defined as macrophytic plant life growing in water or soil or on a substrate that is at least periodically deficient in oxygen as a result of excessive water content (U.S. Army Corps of Engineers 1987}. A list of plants able to tolerate saturated soil conditions has been prepared by the U.S. Fish and Wildlife Service (USFWS; Reed 1988; USFWS 1993}. Vascular plants are classified according to their affinity for wetland areas, and thus their probability of being found in a wetland. There are five wetland indicator status ratings, as defined below: Wetland Delineation and Stream Assessment 2-3 August 2008 05570-045-0400 EI~SR • Obligate Wetland (OBL): Under natural conditions, plants occur almost exclusively in wetlands (estimated probability >99 percent}. • Facultative Wetland (FACW): Plants usually occur in wetlands (estimated probability 67 to 99 percent), but are occasionally found innon-wetlands. • Facultative (FAC): Plants are equally likely to occur in wetlands and non-wetlands (estimated probability 34 to 66 percent}. • Facultative Upland (FACU): Plants usually occur in non-wetlands (estimated probability 67 to 99 percent}, but are occasionally found in wetlands (estimated probability 1 to 33 percent). • Obligate Upland (UPL): Plants may occur in wetlands in another region, but under natural conditions almost always occur innon-wetlands in the region specified (estimated probability >99 percent}. Wetland indicator categories should not be equated to degrees of wetness. Many Obligate Wetland species occur in permanently or semipermanently flooded wetlands, but a number also occur in, or are restricted to, wetlands that are only temporarily or seasonally flooded. The actual frequency of occurrence of a species in wetlands may be anywhere within the frequency range of the indicator category. For example, a species assigned to the Facultative Upland indicator category may actually have a frequency toward the lower end of the category, while another species may have a frequency toward the upper end of the category (Reed 1988}. The presence of hydrophytic vegetation is determined using the wetland indicator status of species encountered. Hydrophytic plants are those rated as FACW or wetter. Wetland boundaries are identified based on the presence of a wetland plant community, rather than any one particular indicator species. For example, a plant community with scattered individual upland species, but dominated by hydrophytic species, is considered to be a wetland community. Within each wetland, specific communities are determined on the basis of their dominant plant species, soils, and hydrology. 2.2.5 Classification Wetlands delineated in the project area are classified using the USFWS wetland hierachical classification system (Cowardin et a1.1979}.This system classifies wetlands according to hydrologic, geomorphologic, chemical, and biological factors. Wetlands are first classified by the primary source of water to the wetland. These classes are usually identified by the physical form of the dominant vegetation community type or, less often, the substrate of the wetland. Only one type of primary wetland system, palustrine, is applicable to wetlands on the study site. Palustrine Systems are shallow ponds and wet areas, including all non-tidal wetlands dominated by trees, shrubs, persistent emergents, emergent mosses, or lichens. This system also includes wetlands lacking such vegetation, but with all of the following four characteristics: l)total area is less than 8 ha (20 acres}; 2} active wave-formed or bedrock shoreline features are lacking; 3) water depth in the deepest part of the basin is less than 2 m (6.6 feet} at low water; and 4} salinity, due to ocean-derived salts, is less than 0.5 parts per thousand. Descriptions of other wetland systems may be found in Cowardin et al. (1979). Systems are divided into more specific categories called subsystems, although there are no subsystems within the Palustrine System. The classification system further identifies wetlands by dividing them into different classes based on general appearance of the life form in the plant community (e.g., trees, shrubs, aquatic vegetation}, and subclasses based on finer differences in life form. Wetland Delineation and Stream Assessment 2-4 August 2008 05570-045-0400 EI~SR Palustrine classes pertinent to the study site include Forested, Scrub-Shrub, and Emergent. These classes are defined as follows (definitions from Cowardin et a1.1979}: • Forested -Characterized by woody vegetation that is 6 m (19.7 ft) or taller (abbreviated as PFO in this report}. • Scrub-Shrub -Includes areas dominated by woody vegetation less than 6 m (19.7 ft} tall. The species include true shrubs, young trees, and trees or shrubs that are small or stunted because of environmental conditions (abbreviated as PSS}. • Emergent -characterized by erect, rooted, herbaceous hydrophytes, excluding mosses and lichens. This vegetation is present for most of the growing season in most years. These wetlands are usually dominated by perennial plants (abbreviated as PEM}. Palustrine classes normally found within the stream channel (rock bottom, unconsolidated bottom, aquatic bed, and unconsolidated shore} are classified in this report as Open Water (abbreviated as POW). 2.2.6 Wetland Rating Wetlands delineated at the study site were rated according to the criteria presented in the Auburn CAO. Numerical rating criteria follow the point-based system provided in the Washington State Wetland Rating System for Western Washington (Hruby 2004}.This system scores wetlands on the basis of their sensitivity to disturbance, the functions they provide, and whether they can be replaced. Based on a series of questions about attributes of the wetland and the surrounding areas, scores pertaining to water quality functions, hydrologic functions, and habitat functions are generated. In some cases, wetlands may also be categorized on the basis of special characteristics. According to the Auburn CAO, there are five categories of wetlands, which are briefly described below: Category I Wetlands that meet any of the following criteria: a} represent a unique or rare wetland type; or b} are more sensitive to disturbance than most wetlands; or c} are relatively undisturbed and contain ecological functions that are impossible to replace within a human lifetime; or d} provide a high level of functions (scoring 70 points or more out of 100 in the Washington State Wetland Rating System for Western Washington); or e} are characterized as a national heritage wetland; or f) are characterized as a bog; or g} are over 1 acre and characterized as a mature and old-growth forested wetland. Category II Wetlands that are not Category I Wetlands and that meet any of the following criteria: a} provide high levels of some functions, being difficult, though not impossible to replace; or b} perform most functions relatively well (scoring 51 to 69 out of 100 points}. Category III Wetlands that are not Category I or II wetlands, and that meet the following criterion: provide moderate levels of functions (scoring 30 to 50 out of 100 points). Category IV Wetlands that meet the following criterion: provide low levels of functions (scoring less than 30 out of 100 points). Artificially Created Wetlands that are purposefully created landscape features, ponds, or storm water detention or retention facilities. Artificially created wetlands do not include wetlands created as mitigation or wetlands modified for approved land use activities. Wetland Delineation and Stream Assessment 2-5 August 2008 05570-045-0400 EI~SR 2.2.7 Field Evaluation Afield survey of the study area was conducted on March 1, 3, 5, and and April 17,18, and 25, 2008, to identify, delineate, categorize, and map wetlands occurring on the study site. Additionally, a short, follow-up visit was made on May 19, 2008. Field evaluations followed methodology presented in the Washington State Wetlands Identification and Delineation Manual (Washington Department of Ecology 1997}. Project Corridor. Given the narrowness of the main survey corridor, biologists walked one survey line, from the western edge to the eastern edge, using aerial photos and field markers (blue and pink flagging} to determine the boundaries of the study area. In order to ensure that the entire project area was covered, surveyors meandered along the corridor, investigating all potential wetlands and areas where the plant community type changed. Areas outside the corridor were also investigated, as allowed by accessibility, to determine whether wetlands were present adjacent to the project corridor that could potentially affected by proposed construction activities. Along the steep slope at the east end of the corridor, surveyors were restricted to walking along the blazed trail, but looked for changes in vegetation to either side of the trail that could indicate the presence of a wetland. At the base of the slope, surveyors searched the study area to look for the "existing potential wetland" mapped by the city of Auburn. Additionally, the hydrology and soils at the very base of the slope were examined to determine whether there was any seepage of groundwater that could be an indicator of wetlands on the hillslope. Since a wetland delineation was conducted in a portion of the project corridor in 2007, surveyors looked for flagging that would indicate the boundaries of previously-delineated wetlands. There was extensive white flagging in the corridor, some of which appeared to correspond to wetland boundaries, and some of which appeared to mark other things, such as property lines. Previously-delineated wetlands within the study area were re-delineated. In the case of the large wetland associated with the stream channel, weonly re-delineated the portion of the wetland within the study area and extending beyond the study area boundary a distance of approximately 200 feet. Christopher Substation Site. At the Christopher substation site, two transects were run east-west across representative portions of the area, with one crossing the open area in the southern half of the property, and one crossing the forested area immediately south of the substation. In lieu of a third transect, surveyors located other sampling points based on apparent changes in plant communities and hydrology. This approach was chosen because the site has been modified from its original conditions in many areas, primarily through the deposition of fill. Selection of sampling points allowed surveyors to include altered areas that would have been missed by a third transect. For most of the site, wetland boundaries were delineated based on plant species composition, soil characteristics, and hydrological characteristics. However in areas identified by PSE as digging hazard areas (i.e., areas with a potential for having underground utilities), soils were not characterized. Boundaries of all wetlands encountered were flagged and then mapped using an 8-channel Trimble Pro XR Global Positioning System (GPS} with beacon with an accuracy of approximately 0.5 meters. Completed field data forms for wetlands delineated, as well as representative adjacent upland areas, can be found in Appendix A. Each wetland was classified using the USFWS classification system (described in Section 2.2.5} and rated using the Washington State Wetland Rating System for Western Washington (Hruby 2004} and the criteria given in the Auburn CAO. Completed wetland rating forms have been provided in Appendix B. During field surveys, biologists noted any wildlife species that were encountered, paying particular attention to native and priority species. Wetland Delineation and Stream Assessment 2-6 August 2008 05570-045-0400 EI~SR 2.3 Stream Assessment 2.3.1 Stream Identification and Mapping Streams in the study area were located using a combination of King County stream GIS data, aerial photographs, and field reconnaissance. The portion of each stream within the study area was mapped on foot using GPS. In the case of Mill Creek, both banks of the stream channel were mapped at wetted width (the extent of surface water in the channel}.The remaining stream channels in the project area were too narrow to map both sides of the channel within the range of accuracy of the GPS, so these streams were mapped as a single line, as close to the middle of the stream channel as possible. In the project corridor, just the portion of the stream channel within the study area was mapped in the field. This stretch of the stream was checked against the King County GIS layer to verify its accuracy. 2.3.2 Stream Characterization Important stream characteristics were recorded at a series of points along the length of each stream. Sampling points were spaced approximately 250 feet apart. For several of the small, manmade drainage ditches with little habitat diversity, sampling points were spaced at larger intervals. The following information was recorded at each stream sampling point: Stream bed type. We described the size, texture, color, and variability of sediments comprising the stream channel, as well as other materials found on the stream bed, such as organic matter. Channel profile. To the extent possible, we measured the depth of the stream across its channel to produce a rough profile. In some areas, water depth and/or dense vegetation prevented this measurement. Channel width. We estimated the width of the channel, including wetted width and bank width (the distance between the high water mark on either side of the channel. Rate and direction of flow. We rated the velocity of water in the stream at surface level as slow, moderate, or fast. We determined the approximate direction of flow. Surrounding cover. We recorded the dominant species of vegetation surrounding the stream channel and the height of the vegetation. We ranked the amount of shading of the stream as none, partial, or nearly complete. Habitat characteristics. We noted any retention structures in the stream channel, such as protruding rocks and large woody debris. We described the habitat complexity of the stream, including its sinuosity, presence of riffles and pools, channel braiding, and tributaries. Biological characteristics. We recorded the presence offish, invertebrates, aquatic plants, and other species observed in the stream. Information for each sampling point was recorded on stream assessment data sheets, which are included in Appendix C. Additionally, photographs were taken facing upstream and downstream from each sampling point, which are included in Appendix D. 2.3.3 Stream Classification Streams located during field surveys were classified accordance with Auburn CAO regulations. There are five classes of streams, as described below. Wetland Delineation and Stream Assessment 2-7 August 2008 05570-045-0400 EI~SR Class I Natural streams identified as "shorelines of the state" under the City of Auburn shoreline master program. Class II Natural streams that are not Class I streams and are either perennial or intermittent and have one of the following characteristics: a) contain fish habitat; or b) have significant recreational value. Class III Natural streams with perennial or intermittent flow that do not contain fish habitat. Class IV Natural streams and drainage swales with channel width less than 2 feet taken at the ordinary high water mark, that do not contain fish habitat. Intentionally Created Manmade streams, but not including streams created as mitigation. Intentionally created streams may include irrigation and drainage ditches, grass-lined swales, and canals. These streams are excluded from regulation under City of Auburn regulations, except manmade streams that provide critical habitat (designated at the federal or state level) for salmonids. Wetland Delineation and Stream Assessment 2-$ August 2008 05570-045-0400 ENSR 3.0 Results 3.1 Wetland Descriptions During field surveys, five wetlands (called wetlands A through E in this report} were delineated in the study area, as shown in Figures 3-1, 3-2, and 3-3. Wetlands A through D are located along the project corridor, and wetland E is located on the Christopher Substation Parcel. These wetlands are described in more detail in the sections that follow. During the surveys, the air temperature was typically between 40 and 60 °F, and weather ranged from clear to rainy. Although surveys began early in the year, visual observations of new vegetative growth provided evidence that the growing season had begun. However, many plant species were still in their dormant phase at the time of surveys, particularly at the Christopher Substation Site. 3.1.1 Wetland A Wetland A is a small, depressional PEM wetland, approximately 0.025 acres (1,100 square feet} in size (Figure 3-1 It is located in an open, disturbed area near the western end of the project corridor. Dominant species include orchard grass, creeping buttercup (Ranunculus repens}, and common velvetgrass (Holcus lanatus}.This wetland occurs at a site of possible fill deposition, as evidenced by the presence of a wooden stake deep in the soil pit. The wetland has been classified as Category IV. It has moderate water quality functions, but low hydrologic and habitat functions. Please note that although this wetland is pictured in an area with tree cover on Figure 3-1, the area has been cleared since 2002 when the photo was taken. 3.1.2 Wetland B Wetland B is a small PEM wetland, approximately 0.027 acres (1,190 square feet} in size (Figure 3-1}. It is a narrow ditch, approximately 2 feet wide, with banks about 1 foot high. The ditch is oriented roughly north-south and appears to serve as a channel for surface water from upslope areas during wet periods. Dominant plant species include creeping buttercup, bentgrass, orchard grass, and stinging nettle. This wetland is located just east of a moist wooded area. It has been classified as Category IV. It has moderate water quality functions, but low hydrologic and habitat functions. 3.1.3 Wetland C Wetland C is a large PEM1PF01PSS wetland associated with a stream channel that extends beyond the survey area to the north and south (Figure 3-3}.Approximately 0.5 acres of this wetland are located within the study area, but the entire wetland is much larger, extending north and south from the study area as it follows the stream channel. This wetland was mapped and rated previously as part of a delineation for a proposed housing development (D.R. Strong Consulting Engineers 2007}.The wetland boundaries shown in the drawings are similar to those delineated by ENSR, except that it was divided into two wetlands by the previous delineators. ENSR delineated a single wetland centered about the stream channel. The emergent portion is dominated by bentgrass, orchard grass, tall fescue (Schedonorus phoenix), and meadow buttercup. In the wetter portions, common rush becomes more prevalent. The forested portion of the wetland is a riparian area along the stream channel. The predominant tree species is red alder, with a Himalayan blackberry understory. The scrub-shrub portion of the wetland is dominated by Himalayan blackberry. Wetland C has been classified as a Category II wetland, primarily because it has a high potential, and the opportunity, to reduce flooding and erosion and improve water quality.

This wetland was delineated in 2007, although with slightly different boundaries. The emergent portion is dominated by orchard grass, common rush, and meadow buttercup, with small areas of reed canarygrass. The dominant tree in the forested portion is red alder, and understory dominants include Himalayan blackberry and Indian plum (Oemleria cerasiformis}. Herbaceous dominants in the forested portion include meadow buttercup and large-leaved avens (Geum macrophyllum). The scrub-shrub portion consists almost entirely of Himalayan blackberry. Wetland D has been classified as a Category III wetland. It has low hydrologic functions and moderate water quality and habitat functions. 3.1.5 Wetland E Wetland E is a single large PEM/PSS/PFO riverine wetland that occupies that majority of the Christopher Substation site. Although pieces of it were mapped as separate small wetlands in a 2006 critical areas report (David Evans and Associates Inc. 2006}, hydrologic connections over the entire site require it to be considered a single wetland. It appears that prior to filling portions of the area, the entire 70-acre site was a wetland. However, deposition of fill has altered the hydrology in some portions of the site enough that isolated areas no longer function as wetlands. These sites have been mapped as upland areas, as shown on Figure 3-3. It should be noted that some areas where fill has been deposited, but wetland hydrology has persisted, are currently functioning as wetlands despite their altered soils. These areas have been mapped as wetlands. Wetland E is approximately 59 acres (2,567,000 square feet} in size (with upland inclusions subtracted}.The PEM component is predominant, at approximately 46.6 acres (2,028,000 square feet},followed by PFO (8.4 acres; 365,000 square feet} and PSS (4.0 acres;173,000square feet). Because the POW component is very small and difficult to separate out, it has been lumped with the more dominant components accordingly. Within the PEM component, reed canarygrass is nearly ubiquitous. This species forms a dense coverage of most of the wetland, and dominates many of the upland inclusions as well. In more deeply inundated areas, cattail is the dominant species. In the forested wetland portions, red alder and willows are prevalent along streams, and red alder and balsam poplar are prevalent in other areas. Where the forest ismulti-layered (i.e., non-riparian areas behind the substation}, red-osier dogwood is an important understory component, and creeping buttercup is predominant in the herbaceous layer. The PSS component occurs primarily along portions of the creek and drainage ditches. Dominant species are Douglas spirea and red-osier dogwood, with some Himalayan blackberry where the wetland is transitioning to upland. This wetland has been rated as a Category II wetland. It has moderate water quality functions, and high hydrologic and habitat functions. Additionally, the wetland may be subject to increased protection requirements because Mill Creek is utilized by listed salmonid species, and because the wetland contains a priority species, the great blue heron (Ardea herodias}. 3.1.6 Wetlands Previously Mapped but not Delineated in the Current Study The City of Auburn has an "existing potential wetland" mapped at the eastern edge of the proposed project corridor, just west of West Valley Highway, at the base of the steep slope in this portion of the study area. Surveyors looked for signs of wetlands in this area, paying special attention to the base of the slope. A sample plot was placed at the base of the slope, and hydrology, soils, and vegetation were characterized. We found no evidence of wetlands in this area. ENSR located all of the wetlands delineated along the project corridor in 2007.One of these wetlands (labeled "Tract J" on the Road, Grading, and Storm Drainage Plan; D.R. Strong Consulting Engineers 2007} is shown with a small lobe to the north of the main wetland, with a resultant buffer that comes within 75 feet of the proposed project corridor. Because it was outside of the study area, ENSR did not delineate this wetland, but Wetland Delineation and Stream Assessment 3-5 August 2008 05570-045-0400 ENSR did field-check it to make sure that it does not extend farther than depicted on the map. We confirmed that the main portion of the wetland was fairly accurately mapped. However, we did not verify the presence of the northern lobe. There was no evidence of wetland hydrology in this area, although 50% of the dominants were FAC or wetter and soils displayed borderline hydric characteristics. It is possible that the previous delineation occurred very recently after a rain and wetland hydrology appeared to be present at that time. ENSR noted a similar wet area at another location in the corridor with borderline wetland vegetation, soils, and hydrology at the time of the delineation, which was after a recent rain. After flagging and mapping the wetland, ENSR revisited the site after several consecutive dry days. On this second visit, there was no evidence of wetland hydrology. It is our opinion that these areas are not wetlands, although they may be wetter than adjacent upland areas in the surrounding landscape. The approximate location of the previously delineated wetland, with the northern lobe removed, is shown on Figure 3-2. 3.2 Stream Assessment The results of the stream assessment are summarized below for each stream identified in the study area. 3.2.1 Streams in the Project Corridor The stream labeled as "KC Stream" in King County GIS layers flows roughly to the north through the project corridor, approximately midway along the corridor (Figure 3-2}.The portion of the stream channel within the study area, asfield-checked by ENSR using GPS, matches well with the location of the stream in the GIS data layer provided by King County. Therefore, Figure 3-2 displays the King County data in order to show more of the stream channel than we mapped in the field. The stream varies from 1 to 4 feet in width and from 1 to 6 inches in depth within the corridor, and flow velocity in moderate. The sediment on the stream bottom is diverse in size, ranging from sand particles less than 1 millimeter in diameter to cobbles greater than 15 centimeters in diameter. The channel profile is nearly square, with steep, sharply cut banks. Surrounding vegetation includes common rush, orchard grass, and blackberry, with vegetation height ranging from 8 inches to 8 feet. The degree of stream shading is almost none in areas surrounded by grasses, but partial in areas surrounded by blackberry. The area on both sides of the stream is a wetland, and in some areas surface water can be seen flowing directly into the stream. Habitat complexity of the stream is minimal. The stream exhibits almost no sinuosity, braiding, riffles and pools, or retention structures. No fish were observed in KC stream, which is probably too shallow to support fish. According to WDFW, the creek is not utilized by fish. However, several types of macroinvertebrates were found on the stream bed, and algae were observed growing on larger sediments. According to the guidance in the Auburn CAO, this stream is classified as Class III Stream. 3.2.2 Streams at the Christopher Substation Site Mill Creek. Mill Creek enters the Christopher Substation site approximately midway along the southern boundary after flowing beneath 29t" Street NW (Figure 3-3). The stream splits into two branches almost immediately upon entering the site. The west branch flows west just inside the southern site boundary, then makes a 90 degree turn and flows north just inside the western site boundary. When it reaches the northern site boundary, the west branch flows through a culvert beneath 37t" Street NW and out of the site. The east branch of Mill Creek flows north from the southern site boundary through the center of the site until it reaches the boundary of a forested wetland area. At this point, the stream channel becomes indistinguishable as it expands into a large area of shallow open water. The location of Mill Creek as mapped in the field corresponds well with the location mapped by the City of Auburn. According to WDFW, the portion of Mill Creek within the Christopher Substation site contains fall Chinook salmon (Oncorhyncus tshawytscha), winter steelhead (0. Wetland Delineation and Stream Assessment 3-6 August 2008 05570-045-0400 EI~SR mykiss}, and coho salmon (0. kisutch}.Therefore, according to Auburn CAO regulations, this stream is classified as a Class II stream. West Branch -The west branch of Mill Creek is the largest stream in the study area and provides the highest quality aquatic habitat. The substrate comprising the stream bed is a fine, muddy silt with sediment particles less than 1 millimeter in diameter. The sediment ranges in color from a light brown to a dark green, but there is almost no variability in particle size or texture along the stream. In areas with deep, slow water, organic matter such as decomposing leaves and twigs has collected on the stream bottom. The wetted width of the channel is variable along its length, ranging from 4 to 22 feet at the time of the survey, with an average of about 15 feet. Bank width varies from 4 to 32 feet and averages about 20 feet. The rate of flow of the stream is slow to moderate, with barely perceptible flow in deep pool areas and faster flow with surface ripples in a few areas. The channel profile is generally rounded, although in some areas the deepest part of the channel lies to one side of the channel. Waterdepth in the deepest part of the channel is typically between 4 and 6 feet. Dominant vegetation species surrounding the stream include reed canarygrass, red alder, and willows, with cattail, Himalayan blackberry, and birch (Betula sp.}found less commonly. Surrounding vegetation height varies from 2 feet to 40 feet, and the degree of stream shading ranges from none to nearly complete shading. Retention structures within the stream are generally uncommon along the west branch, with infrequent, small- diameterwoody debris and overhanging branches from live trees in the stream channel. There is little habitat complexity along most of the stream as a result of the previous rerouting and channelization of the stream. Riffles and pools are uncommon, and there is little braiding of the channel. In the portion of the stream near the southwest corner of the site, however, there are several pieces of large-diameter woody debris that have created deep pools and cover habitat for fish and other aquatic species. This area likely represents the best available fish habitat within the study area. No fish or other aquatic animal species were observed in the stream. Although fish are reported to occur in this area, the fine, homogenous substrate of this portion of the stream provides poor conditions for most aquatic macroinvertebrates and fish. East Branch -The east branch of Mill Creek flows north through emergent wetland habitat composed almost entirely of reed canarygrass. Along nearly the entire east branch, the substrate is a light brown, fine silt with particles less than 1 mm in diameter. A few larger cobbles are found at the extreme southern end of the east branch. Bank width varies from 10 to 30 feet, and wetted width varies from 8 to 20 feet. Flow velocity is extremely slow along the entire stream course. Water depth in the deepest part of the channel ranges from 2 feet to over 4 feet but is believed to be less than 6 feet throughout the stream. Reed canarygrass is the dominant vegetation surrounding the stream, but Douglas spirea, Himalayan blackberry, and black hawthorn (Crataegus douglasi~} are also present along portions of the stream banks. Vegetation height is generally less than 3 feet. Stream shading ranges from almost none to partial shade. With the exception of some slight channel meandering and in-stream vegetation, the east branch exhibits almost no habitat complexity. No fish or other aquatic animal species were observed in the stream. Although fish are reported to occur in this area, the fine, homogeneous sediment makes it unlikely that many macroinvertebrates are found in this portion of the stream channel. Other Streams. Drainage ditches were identified within the Christopher Substation site running along the northern, eastern, and southern boundaries of the site. These ditches appear to be hydrologically connected, although the direction of flow is unclear in some areas, and they are apparently manmade. These manmade channels are classified as "Intentionally Created Streams" under the Auburn CAO, and are excluded from regulation. A ditch along the northern boundary of the site flows west into Mill Creek at the point where it flows beneath 37t" Street NW. This north drainage ditch is 4 to 6 feet wide and 1 to 2 feet deep, and it appears to Wetland Delineation and Stream Assessment 3-7 August 2008 05570-045-0400 EI~SR receive wetland runoff from the north end of the site. The drainage ditch along the eastern site boundary is more diverse, with open water cattail marshes at its northern and southern ends and a thicket of Himalayan blackberry and Douglas spirea in the middle. There is no perceptible direction of flow along this drainage ditch. The southern drainage ditch flows west along the site boundary until it meets the junction of the east and west branches of Mill Creek. This ditch is 2 to 4 feet wide and 2 feet deep, and is heavily clogged with aquatic vegetation resembling algae. None of the drainage ditches identified in the site provide suitable habitat for fish, nor are they mapped in King County GIS data. An additional drainage ditch was identified along the west boundary of the Christopher Substation site, west of Mill Creek, but lies just beyond the site's western property line on the far side of a wire fence. This channel was not mapped in the field. 3.3 Wildlife Observations Although a formal wildlife survey and functions and values assessment was not included in the scope of this project, biologists did note wildlife species during the course of wetland delineations and stream assessments. These observations are summarized in this section Along the proposed project corridor, ENSR biologists saw or heard the following bird species: American crow (Corvus brachyrhynchos), American robin (Turdus migratorius}, Steller's jay (Cyanocitta steller~), northern flicker (Colaptes auratus}, dark-eyed junco (Junco hyemalis}, black-capped chickadee (Poecile atricapilla, and pileated woodpecker (Dryocopus pileatus}.Most of these birds were associated with patches of forested habitat within and near the corridor. Additionally, an active red-tailed hawk (Buteo jamaicensis} nest was observed at the east of the project corridor, near the West Valley Highway. The only mammal encountered was a rabbit or hare of unknown species. Out of species encountered, only pileated woodpecker is a priority species, with breeding areas considered priority areas. Biologists did not confirm the presence of breeding areas in the project corridor; it is more likely that suitable breeding habitat would be located in the forested area to the north of the project corridor. At the Christopher Substation site, biologists noted coyote scat in numerous places along grassy roads/trails within the site. Bird and waterfowl species observed along and near Mill Creek include American bittern (Botaurus lentiginosus}, black-and-white warbler (Mniotilta varia}, hooded merganser (Lophodytes cucullatus}, mallard (Anas platyrhynchos}, marsh wren (Cistothorus palustris}, and song sparrow (Melospiza melodia}. Near the drainage ditch along the site's eastern boundary, biologists saw American crows, hooded mergansers, red-winged blackbirds (Agelaius phoeniceus), and brown-headed cowbirds (Molothrus ater}. Bird species observed in forested areas in the north end of the site include downy woodpecker (Picoides pubescens}, black-capped chickadee, American robin, and song sparrow. Marsh wren was common at the site, and was heard in many locations within emergent wetland areas dominated by reed canarygrass. Two great blue herons and a northern flicker were seen flying over the central portion of the site. An active red- tailed hawk nest was observed near the southwest corner of the substation. Of the species observed at the site, great blue heron is considered a priority species by WDFW. Breeding areas are considered priority habitats. No great blue heron nests were observed in forested areas on the site, so use of this area as breeding habitat cannot be confirmed. The observed birds could possibly be part of a large breeding colony of herons roughly 2 miles south of the site. Wetland Delineation and Stream Assessment 3-8 August 2008 05570-045-0400 EI~SR 4.0 Buffers and Mitigation Ratios Figures 4-1 and 4-2 show the delineated wetlands and surveyed streams along the project corridor, with their required buffers, as directed by the Auburn CAO. Additional information is provided in the sections that follow. Since almost the entire Christopher Substation site is a wetland, a figure showing wetland buffers at this site has not been included. However, mitigation requirements pertaining to the site are provided below. Figure 4-3 shows the breakdown of wetland types at the Christopher Substation site, overlain by a PSE-provided construction drawing showing the proposed alignment of the transmission line. According to this drawing, the proposed project could potentially impact emergent and forested wetland habitat. 4.1 Wetlands 4.1.1 Required Buffers According to the Auburn CAO, wetland buffers are determined based on the rating of the wetland, site conditions, site design, and intensity and operational characteristics of the developmentlland use. Minimum and maximum buffer widths have been established for each wetland category. Table 4-1 summarizes the minimum buffers required for the five delineated wetlands, as well as the potential maximum buffer width for each. Table 4.1 Required City of Auburn Wetland Buffers Wetland Size acres Cate or Minimum Buffer Maximum ( ) 9 y Width (ft) Buffer Width (ft) A 0.025 IV 25 30 B 0.027 IV 25 30 C Not determined II 50 100 D 0.3 III 25 50 E 59 II 50 100 The need for increased buffer widths, up to the maximums listed above, is determined by the director of the City of Auburn Department of Planning and Community Development, as necessary to protect wetland functions and values. Wetland buffer width averaging, up to a 35 percent reduction in width, may be allowed, under certain conditions, if the site has less than 25 percent slopes and the reduction in width will not result in adverse effects to the wetland. Additionally, the buffer width may be reduced by up to 35 percent if the applicant restores or enhances the buffer by such means as planting native trees or shrubs and replacing exotic species with native species. 4.1.2 Mitigation Ratios The City of Auburn permits some wetland alterations, provided the applicant enhances or creates areas of wetlands to compensate for wetland losses. This required compensation is determined based on acreage, function, type, location, timing factors, and projected success of enhancement or creation. Table 4-2 summarizes the required acreage replacement and enhancement ratios for Category II, III, and IV wetlands. Wetland Delineation and Stream Assessment 4-1 August 2008 05570-045-0400 EI~SR Table 4-2. Wetland Replacement and Enhancement Ratios Wetland Cate or Wetland Creation Ratio Acres Wetland Enhancement 9 y ~ ~ Ratio Acres ~ ~ (Acres Created or Enhanced: Acres Impacted} Category II Forested 3:1 6:1 Scrub-shrub 2:1 4:1 Emergent 2:1 4:1 Category III Forested 3:1 6:1 Scrub-shrub 2:1 4:1 Emergent 2:1 4:1 Category IV 1.25:1 2.5:1 Category IV wetlands can be mitigated by either meeting one of these replacement ratios or implementing mitigation that ensures no net loss of values and functions of the larger ecosystem in which the critical area is located. 4.1.3 Streams According to the Auburn CAO, required stream buffer widths (measured from the ordinary high water mark} are determined based on the class of the stream. Minimum buffer widths for the streams in the study area are summarized in Table 4-3 below. Table 4-3. Required City of Auburn Stream Buffers Stream Stream Class Minimum Buffer Width "KC Stream" III 25 feet Mill Creek II 75 feet Drainage Ditches Intentionally Created Not regulated These buffer widths may be increased by a maximum of 50 percent for all classes of regulated streams except Class III streams, for which buffer widths may be increased by up to 100 percent, based onsite-specific conditions and the functions and values of the stream. Enhancement measures such as removal offish barriers, enhancement of fish and wildlife habitat, and other mitigating measures maybe proposed that will be considered in establishing buffer requirements. Buffer widths may also be reduced on acase-by-case basis, by up to 35 percent, provided that the reduction will not result in any adverse impact to the stream. Given that listed salmonid species are reported to occur in Mill Creek on the Christopher Substation site, required buffers could potentially be greater than the minimum required buffers in order to protect fish habitat. Buffer width averaging may be allowed for Class II and III streams, provided enhancement measures are implemented, the total buffer area does not decrease, stream functions and values will not decrease, and the buffer width is not reduced by more than 35 percent in any location.

Minimum required buffers for these critical areas range from 25 to 50 feet. East of State Route 167, the entire parcel where the Christopher Substation is sited, with the exception of manmade upland inclusions, is a wetland complex. In this area, wetlands cannot be avoided, and PSE must consider mitigation if the proposed project requires fill or alteration of wetland habitat. Additionally, Mill Creek requires a minimum buffer of 75 feet, which could very likely be increased to 100 feet because the stream is known to support listed salmonids.

SP2. Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? ' For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. Note: Wetlands with State listed plant species are cafe orized as Cate o I Natural Herita a wetlands see . l9 of data form . SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? SP4. Does the wetland unit have a local sign~cance in addition to its functions? Far example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To com fete the next art o the data sheet ou will need to determine the H dro eomor hic Class o the wetland bein rated. The hydrogeomorphic classif cation groups wetlands into those that function in similar ways. This simplifies the questions needed ~o answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands.

YES Freshwater Tidal Fringe NO -Saltwater Tidal Fringe Estuarine} If your wetland can be classed as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland. V~etlands that were called .estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the HydrogeomorphicClossification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is ke t. Plea e p s note, however, that the characteristics that def ne Category I and II estuarine wetlands have changed see p. Z. The entire wetland unit is flat and precipitation is the only source ~>9U°/a} of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO - go to 3 YES -The wetland class is Flats If your wetland can be classif ed as a "Flats" wetland, use the form for Depressional wetlands.' 3. Does the entire wetland unit meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of permanent open water without any vegetation on the surface} at least 20 acres ~8 ha} in size; At least 30°l0 of the open water area is deeper than 6.6 ft ~2 m}? NO - go to 4 YES--The wetland class isLake-fringe ~Lacustrine Fringe} 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope slope can be very gradual}, The water flows through the wetland in one direction unidirectional}and usually comes from seeps, It may flow subsurface, as sheetflow, or in a Swale without distinct banks. The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3ft diameter and less than ~ foot deep). NO - go to 5 YES -The wetland class is Slope Wetland Rating Form -western Washington 3 August 2U04 version 2 Wetland name or number 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. ~~TE: The riverine unit can contain depressions that are~lled with water when the river is not flooding. NO - go to 6 YES -The wetland class is Riverine Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at same time during the year. This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES -The wetland class is Depressional Is the entire wetland unit located in a very flat area with no obvious de ression and no averbank . p flooding. The unat does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland ma be ditched, but has no obvious y natural outlet. NO go to 8 YES -The wetland class is Depressional S. Your wetland unit seems to be difficult to classify and probably contains several different HGM cIases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS I APPLY TO DIFFERENT AREAS IN THE UNIT make a rough sketch to help you decide. Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated, If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. ~ . ~ ' N 'h I1 M I n ~ 5 i T I G.

Urban Natural Upen Space: A priority species resides within or is adjacent to the open space and uses it for breeding andlor regular feeding; andlor the open space functions as a corridor connecting other priority habitats, especially those that would otherwise be isolated; andlor the open space is an isolated remnant of natural habitat larger than 4 ha (10 acres} and is surrounded by urban development. EstuarylEstuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi- encIosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean-derived salts measure less than 0.5ppt. during the period of average annual low flow. Includes both estuaries and lagoons. MarinelEstuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent co~aponents of the terrestrial landscape (e.g., cliffs, snags, mature trees, dunes, meadows} that are important to shoreline associated fish and wildlife and that contribute to shoreline function (e.g., sandlrockllog recruitment, nutrient contribution, erosion control}.

Na - go to 2 YES -the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt parts per thousand}? YES -Freshwater Tidal Fringe NU -Saltwater Tidal Fringe Estuarine} If your wetland can be classified as a Freshwater Vidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that def ne Category i and ~I estuarine wetlands have changed see p. 2. The entire wetland unit is flat and precipitation is the only source ~>90%} of water to it. Groundwater and surface water runoff are NaT sources of water to the unit. N0 - go to 3 YES -The wetland class is Flats If your wetland can be classifed as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of permanent open water without any vegetation on the surface} at least 24 acres ~8 ha} in size; At least 30% of the open water area is deeper than 6.6 ft (2 m}? N4 go to 4 YES -The wetland class isLake-fringe ~Lacustrine Fringe} 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope slope can be very gradual}, The water flows through the wetland. in one direction unidirectional}and usually comes from seeps. It may flow subsurface, as sheetflow, or in a Swale without distinct banks. The water leaves the wetland without being impounded? NaTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks depressions are usually ~3ft diameter and less than ~ foot deep}. N0 - go to 5 YES -The wetland class is Slope Wetland Rating Form western Washington 3 August 2004 version 2 Wetland name or number 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at .least once every two years. ~DTE: The riverine unit can contain depressions that are~lled with water when the river is not flooding. NO - go to b YES -The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if ~aresent, is higher than the interior of the wetland. NO - go to 7 YES -The wetland class is Depressional Is the entire wetland unit located in a very flat area with na obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES -The wetland class is Depressional S. Your wetland unit seems to be difficult to cla"ssify and probably contains several different HGM closes. Far example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY 'WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT make a rough sketch to help you decide}. Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10°/a or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. .Yld ki ~ I I 9AI I M~ ' 'I ~ ~GI .I I ~yl.

NO gv to 8 YES -The wetland class is Depressional 8. Your wetland unit seems to be Jiff cult to classify and probably contains several different HGM claws. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide}. Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents I O% or mare of the total area of the wetland unit being rated, If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. ,~11 1 ~ 1 I, ny Y , rr~.i i w ~ ' ~ v J.

If it rs Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that • were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the HydrogeomorphicClasslfication. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is ke t. p Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed see p. 2, The entire wetland unit is flat and precipitation is the only source ~?90%} of water to it. groundwater and surface water runoff are NqT sources of water to the unit. Nq - go to 3 YES--The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3.

It may flow subsurface, as sheetflow, or in a Swale without distinct banks. The water leaves the wetland without bein im ounded? g P NgTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually ~3ft diameter and less than 1 foot deep).

The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. ~V4TE: The riverine unit can contain depressions that are f lred with water when the river is not flooding. NQ - go to 6 YES -The wetland class is Riverine b. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wetland, • ND - go to 7 YES -The wetland class is Depressional Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland. maybe ditched, but has no obvious natural outlet. NQ go to 8 YES ~-The wetland class is Depressional 8. Your wetland unit seems to be diff cult to classify and probably contains several different HGM closes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides.

If it is Saltwater Vidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category r and 11 estuarine wetlands have changed see p. 2.

The unit does not pond surface water mare than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious n~tur~al outlet. N~~~- o to $ YES ~-The wetland class is De ressional g p S. Your wetland unit seems to be difficult to classify and probably contains several different HGM closes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides.

Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area.

The comment letter, signed by Karen Walter, expresses concerns about the report's treatment of streams and their potential to provide habitat for salmonids. _ Comment Number 1- Classification of Stream 0053 Comment Number 1 states that the report incorrectly identifies the small stream crossing the proposed transmission :tine corridor (called KC Stream in the report; referenced as Stream 0053) as a non-salmonid bearing stream. The comment states that coho salmon and cuithroat trout have been observed in this stream, andthaf although there is a known fish blockage af South 277t'; human-created blockages such as this'one "should not be used as a basis for determining fish use in streams ° The comment requesfs thatthis stream be reassessed asa Class II stream for potential impacts. In the report, the stream is classified as a Class III. stream, which is defined in the City of Auburn Critical Areas Ordinance (Chapter 16.10 of the City of Aubum Code; CAO) as a natural stream with perenniaf,or intermittent flow that does not contain fish habifat. The Water Resource Inventory Area (WRIA) 9 Fish Disfibution Maps referenced in the comment indicate that coho salmon and cutfhroat trout should be present in Stream 0053 because of suitable habitat conditions, but are not present because of an artificial barrier (i.e., coded as °Barrier Prevents Presence" in the map legend). The seetion of Stream 0053 referenced bythis statement stretches from South 277"' Street (just south of Mill Creek) south to approximately 1,500 feet downstream of the project area. As stated in the comment letter, annotations to the map also.indicate that both cutthroat trout and coho salmon have been observed in Stream 0053 north (downstream) of South 277th Street. The annotations also state "Coho up to South 277t' St., culvert blockage.° However, the corresponding map label indicating a man-made or natural barrier points to a location on Stream 0053 that is approximately 6,800 feet south of 277"', near 60 and 299t'. This point is approximately 1,500 feet downstream of the project area. South of this point, including within the project area, no additional information on fish distribution within Stream 0053 is presented on the: WRIA Fish Distribution Maps, or on Washington Department of Fish and Wildlife (WDFW) Priority Habitats and Species (PHS) maps: If is not known what sort of a To enhance and sustain the world's buift, naturaf and social environmertts . , AECOM 2 connection there is between the mapped portions ofthe stream and the portion witFiin the project area, although i.n tFie absence of additional information, it should be assumed that the portion of Stream 0053 . witFiin the project area could potenfially provide habitat for coho and cutthroat, should fish be able to access this portion of the stream channel. Our recommendation is that the Gity make a determination ~ about whether to reclassify Stream 0053 or to increase the size of the on-site bufFers, based on'the potential for this portion of the stream to provide fish habitat. The CiVs minimum buffer width designated to protect Class II streams is 75 feet (as measured from the ordinary high water mark). Should this increased bufFer width be established, 'its extension within the project area would .remain within the delineated wetland area on its west side, and within the designated wetland buffer area on the east side Project associated impacts to the wetlands and buffers in this area are addressed in the project's wetland mitigation plan. The vegetation and associated habitats within the wetlands and adjacent buffers are to be enhanced through the installation of native shrubs, which will also.serve to improve the quality ofthe riparian area next fo the stream. Comment Number 2- Use of Ditches on the Christopher Substation Site by Salmonids ~ Comment Number 2 states that the delineation report provides insufficient information for tletermining that ditches on the Christopher Substatiori site are not used by salmonids, and that "the impacts for [fhe proposed] project should consider that these ditches are presumed to be fishbearing streams." The report establishes a hydrologic connection between these ditches and Mill Creek, a known salmon-bearing stream, and then provides an assessment of its habitat characteristics which culminates in the stafement that none of the ditches provide suitable habitat for fish. The most recent information shown on WDFW Priority Habitat and Species maps indicates that the portion of the southem drainage ditch east of the old . . Mill Creek channel is used by coho salmon. Coho salmon is a federal speeies of concem and a WDFW priority species for management and conservation. In order to address this comment, we recommend that . additional information be provided in an addendum to the report that clarifies that all the ditches on fhe site are presumed to be fish-bearing. . Acxording to the City's CAO the southem ditch meets the classficiation criteria as "Intentionally Created . Streams° and therefore would not be subject to regulation by tlie City. However it should be noted that this drainage, as well as other drainage ditches at the site, may be determined to be within the regulatory jurisdiction of applicable State and federal environmental agencies (including, but not exclusively, the Washington State'Department of Ecology,: WDFW, U.S. Army Corps of Engineers, and U.S. Environmental Protection Agency) and therefore subject to regulation. The proposed project will not impact any of the ditches on the Christopher Substation site, or cause changes to existing habitat Comment Number 3- Salmonid Habitat in Mill Creek Comment Number 3 identifies a failure in the delineation report to note that "Mill Creek is an important . stream system that provides significant amounts of low gradient, reed canarygrass lined channels that . provide lower velocity habitats for overwintering juvenile salmonids,° and stresses that °Mill Creek should not be discounted for its value to proyide overwintering habitat for juvenile salmonids." The report sfates that the portion of Mill Creek that flows through the Christopher Substation site contains fall Chinook salmon, winter steelhead, and coho salmon, and for this reason is classified as a Class II stream in accordance with Aubum City code. Therefore, the information provided in the comment letterdoes nof change the assumptions of fish use of Mill Creek within the project area, nor does it change how the stream will be treated for regulatory, purposes: TFie summary provided in Section 3,2.2 of the report provides an assessment of fish hab'itat in stream channels and drainage ditches on the site, based on observations made during the stream assessment conducted during March and Apri12008. While coho salmon may use degraded stream channels, we feel that the overall assessment of habitat quality . provided in the report remains correct. Therefore, we recommend addressing the concems raised in the comment by clarifying that although the habitat is degraded, it may still provide habitat for listed and sensitive salmonicls, and that for project purposes we are assuming that listed and sensitive salmonids . use the portions of Mill Creek within the projecfiarea. To enhance and sustain the world's built, natural and soaal envirnnmertts - . AECOM ' g Comment Number 3 also mentions that the environmental checklist states that °Chinook are limited to the reach of Mill' Greek downstream of 8R 167 without nofing that complete comprehensive surveys of juvenile Chinook use in Mill Creek have never been completed" to the Tribe's knowledge. To respond to this cornment, we recommend that the pertinent text in the checklist under 56 be revised to remove the statement that Chinook are limited to the reach of Mill Creek downstream of SR 167.

This addendum is intended to modify the report, in lieu of a complete report revision. It contains changes to the report, and references the sections where the changes have been made. . This addendum has been prepared in response to concems raised by the Muckleshoot Indian - Tri6e, which were documented in a letter from Karen Waifer of the Tribe to Elizabeth Chamberlain , of, the City of Aubum, dated December 1, 2009. Report Changes in response bo concems that the report provides insuffiaent infoRnation for determining that ditches on the Christopher Substation site are not used by salmonids, the following revisions to the report are.made (in bolded italics): Section 3.1-:5, 3`d paragraph is revised as follows: This wetland has been rated as a Category II wetland. It has moderate water quality functions, and high hydrofogic and habitat functions. Additionally, the wetland may be subject to increased protection requirements because Mill Creek is utilized by listed salmonid species, which may also utilize drainage drtches on the site, and 6ecause the wetiand contains a priority species, the greafi blue heron (Ardea herodias). ~ Section 3.2.2, is revised as fotlows: Mill Creek. Mill Creek enters the Christopher Substation site approximately midway along the southem lioundary after flowing beneath 29t' Street NW (Figure 3-3). The stream splits into two- branches almost immediately upon entering the site. The west branch flows west just inside the southem site boundary, then makes a 90 degree tum and flows north just inside the westem site boundary, When it reaches the northem site boundary, the west branch flows through a culvert _ 6eneath 37"' Street NW and out of the site. The east branch of Mill Creek flows north from the southem site boundary through the center of the site until it reaches the boundary ofi a forested wetand area. At this point, the stream channel becomes indistinguishable as it expands into a (arge area ofishallow open water. The location of Mill Creek as mapped in the field coResponds well with the location mapped by the City of Aubum. According to WDFW, the portion of Mill Creek within the Christopher Substation site contains fall Chinook salmon (Oncorhyncus tshawytscha), winter steelhead (O_ mykiss), and coho salmon (O. kisutch). Therefore, according to Aubum CAO regulations, this stream is classified as a Class II. stream. The descriptions that fol/ow provide assessmenfs of habitat suitabiliiy for fish, as deterrfiined by a biologist in the field. However, it is assumed ftiat degraded stream channe/s may sti/l provide habitat for fish, including listed and serrsitive salmonida.Therefore, if is assumed that listed and sensidve salmonids use the portions of Mi!l Creek within the project ar+ea. West Branch - The west branch of Mill Creek is the largest stream in the sfudy area and provides the highest quality aquatic habitat The substrate comprising the stream bed is a fine, muddy silt with sediment particles less than 1 millimeter in diameter. The sediment ranges in color from a light brown to a dark green, but there is almost no variability in particle size or texture along the , Wetland Delineatlon and Stream AssessmeMAddendum July 2010 05570-05Q-0400 ' . AECOM Report Environment 2 stream. In areas with deep, slow water, organic matter such as decomposing leaves and twigs has collected on the stream bottom. The wetted width of the channel is variable along its length, ranging from 4 to 22 feet at the time of the survey, with an average of about 15 feet. Bank width varies from 4 to 32 feet and averages . abouf 20 feet. The rate ofiflow of the stream is slow to moderate, with barely perceptible flow in deep pool areas and faster ftow witfi sutface ripples in a few areas. The channel profile is generally rounded, although in some areas the deepest part of the channel lies to one side of the channel. Water depth in the deepest part of the channel is typically between 4 and 6 feet. pom'tnant vegetation species surrounding the stream include reed canarygrass, red alder, and willows, wifh cattail, Himalayan blackberry, and birch (Betula sp.) found less wmmonly. Surrounding vegetation height va.ries from 2 feet to 40 feet, and the degree of stream shading - ranges from none to nearly complete shading. Retention structures within the stream are generally uncommon along the west branch, with infrequsnt, small-diameter woody debris and overhanging branches,from live trees in the stream channel: There is litde habitat complexity along most of the stream as a result of the previous . rerouting and channelization of the stream. Riffles and pools are uncommon, and there is little braiding of the channel. In the potfion of the stream near the southwest comer of the site, however, there are:several pieces of large-diameter woody debris that have created deep pools and cover habitat for fish and other aquatic species. This area likely represents the best available fish.habitat within the study area. No fish or other aquatic animal species were observed in the stream. Although fish are reported to occur in this area, the fine, homogenous substrate of this portion of the stream provides poor conditions for most aquatic macroinvertebrates and fish. However, degraded stream channels may still,provide habitatfor listed East 8r•anch - The east branch of Mill Creek flows north through emergent wetland habitat ' composed almost entirely of reed canarygrass: Along nearly the entire east branch, the substrate is a light brown, fine silt with particles less than 1 mm in diameter. A few larger cobbles are found at the extreme southem end of the east brandh. Bank width varies from 10 to 30 feet, and wetted wid4h Varies from 8 to 20 feet. Flow veloaiy is extremely slow along the entire stream course. Water depth in the deepest part of the channel ranges from 2 feeYto over 4 feet but is believed to be less than 6 feet throughout the stream. Reed canarygrass is the dominant vegetation surrounding the stream, but Douglas spirea, Himalayan blackberry, and black hawthom (Crataegus doug/asii) are also present along portions of the stream banks. Vegetation height is generally less than 3 feet: Stream shading ranges from almost none to partial shade. With the exception of some slight channel meandering and in- stream vegetation, the east branch exhibits almost no habitat complexity. No fish or other aquafic animal species w+ere observed in the stream. Although fish are reported to occur in this area, the fine, homogeneous sediment makes it unlikely that many macroinvertebrates are found in this portion of the stream channel. Other Streams. Drainage ditches were identified within the Christopher Substation site nanning along the northem, eastem, and southem boundaries of the site. These ditches appear to be hydrologically connected, although the direction of flow is unclear in some areas, and they are apparently manmade. The ditches are hydro/ogically connected fo Mi!! Creek.

AECOM Report Environment . ~ Introd uction This report is an addendum to the August 2008 ChristopherSubsta6on to 51-q Avenue South Wetland Delinea6on and Stream Assessment (report), prepared for Puget Sound Energy by AECOM. This addendum is intended to modify the report, in lieu of a complete report revision. It contains changes to the report, and references the sections where the changes have been made.. This addendum has been prepared in response to concerns raised by the Muckleshoot Intlian Tribe, which were documented in a letter from Karen Walter of the Tribe to Elizabeth Chamberiain of the City of Aubum; dated December 1, 2009: - Report Changes - In response to concems that the report provides insufficient information for determining that ditches on the Christopher Substation site are not used by salmonids, the following revisionsto the report are made - (in bolded italics): Section 3.1.5, 3`d paragraph is revised as follows: This wetland has been rated as a Category II wetland. It has moderate waterquality functions, and high hydrologic and habitat functions. Additionally, the wetland may be subject to increased protection requirements because Mill Creek is utilized by listed salmonid species, which may a/so utilize drainage ditches on the site, and because the wetland contains a priority species, the.great blue heron (Ardea hemdias). Section 3.2.2; is revised as follows: , • Mill Creek. Mill Creek enters ffie Christopher Substation site approbmately midway along the southem bounciary after flowing beneath 29"' Street NW (Figure 3-3). The stream splRs into two branches almost immedia.tely upon entering the site. The west branch flows west just inside the southem site boundary, then makes a 90 degree tum and flows north just inside the westem site boundary. When it reaches the northem site` boundary, :thewesf branch flows through a culvert beneath 37th Street NW and out of the site. The east branch of Mill Creek flows north from the southem site boundary through the center of the site until it reaches the boundary of a forested wetland area..At.this point, the stream channel becomes indistinguishable as it expands into a large area of shallow open water. The location of Mill Creek as mapped in the field coResponds well with the location mapped 6y #he City of Aubum. According to WDFW, the portion of Mill Creek within the Christopher Substation site contains fall Chinook salmon (Oncorfiyncus tshawytscha), winter steelhead (O. mykiss), and coho salmon (O. kisiitch). Therefore, - accorcling to Aubum CAO regul.ations, this stream is classfiecl as a Clas.s Il stream. Tiie descriptions. , that follow provide assessments of habitat suitability for frsh, as determined by a bio/ogist in the feld. However, it is assumed thaf degraded stream channels may stil/ pcovide habitat for frsh, including listed and sensitive sa/monids. Therefore, it is assumed that /istecl and sensifive salmonids use the portions of Mill Creek within the project area. WesfBranch - The west branch of Mill Creek is the largest stream in the study area and provides the highe5fi qua[ity aquatic habitaf: The substrate comprising the stream bed is a fine, muddy silt with sediment particles less th.an 1 millimeter in diameter. The sediment ranges in color from a light brown to a dark green, but there is almost no variability in particle size or texture along the stream. In areas with deep, slow water, organic matter such as decomposing leaves and iwigs has collected on the stream bottom. The wetted width of the channel is variable along its length, ranging from 4 to 22 feet af the time of the survey, with an average of about 15 feef. Bank width varies from 4 to 32 feet and averages about 20 feet. The rate of flow of the sfream is slow to moderate, with. Liarely perceptible flow in. deep pool areas and faster flow with surface ripptes in a few areas. The channel profile is generally rounded, atthough in WeUand Del'meation and Stream AssessmeM Addendum January 2011 05570-050-0400 AECOM . Report Environment 2 some. areas the deepest part of the ehannel.lies to one side of the channel. Water depth in the deepest part of the channel is typically between 4 and 6 feet: ~ Dominantvegetation species surrounding the stream inctude reed canarygrass, red alder, and willows, with cattail; Himalayan blackberry, and birch (Betula sp.) found less commonly. Surrounding vegetation height varies from 2 feetto~40 feet, and the degree of stream shading ranges from none to nearly complete shading. Reterrtion structures witfiin the stream are generally uncommon along the west branch, with infrequent, small-diameter woody debris and overhanging branches from live trees in the stream channel. There is ("dtle habitat complexity along most of the stream as a result of the previous rerouting and channelization of the stream. Riffles and pools are uncommon, and there is little.braiding of the channel. In the portion of the stream near the southwest c4mer of the site, however, there are several pieces of large-diameter woody debris that have created deep pools and cover habitat for fish and other aquatic species. This area likely represents the best available fish habitat within the study area. No fish or other aquatic animal species were observed in the stream. Atthough fish are reported to occur in this area, the fine, homogenous substrate of this portion of the stream provides poor conditions for most aquatic macroinvertebrates and fish. However, degraded stream channels may still provide habitat for listed East Branch - The east branch of Mill Creek flows north through emergent wetland habitat composed almost errtirely of reed canarygrass. Along nearfy the entire east branch, the substrate is a light brown, fine silt with particles less than 1 mm in diameter. A few largercobbles are found at the extreme southem end of the east branch. Bank width varies ftom 10 to 30 feet, and wetted width varies from 8 to 20 feet. Flow velocity is extremely slow along the entire stream course. Water depth in the deepest part of the channel ranges from 2 feet to over 4 feet but is believed to be less than 6 feet throughout the stream. Reed canarygrass is the dominarrt vegetation surrounding the stream, but Douglas spirea, Himalayan blackberry, and black hawthom (Crataegus douglasir) are also present along portions of the stream banks. Vegetatiori height is generally less than 3 feet. Stream shading ranges from almost none to partial shade. With the exception of some slight channel meandering.and in-stream vegetation, the east branch exhibits almost no habitat complexity. No fish or other aquatic animal specieswere observed in the stream. Although fish are reported to occur in this area, the fine, homogeneous sediment makes it unlikely that many macroinvertebrates are found in this portion of the stream channel. OtherStreams. Drainage ditches were identified within the Christopher Substation site running along the northem, eastem, and. southem boundaries of the site. These ditches appear to be hydrologically connected, afthough the direction ofi flow is unclear in some areas, and they are apparently manmade. The dil+ches are hydrologica/ly connected to Mill Creek. A ditch along the northem boundary of the site flows west into Mill Creek at the point where it flows beneath 37"' Street NW. This north drainage ditch is 4 to 6 feet wide and 1 to 2 feet deep, and it appears to receive wetland runoff from the north end of the site. The drainage ditch along the easfem site boundary is more diverse, with open water cattail marshes at its northem and southem ends and a thicket of Himalayan blackberry and Douglas spirea in the middle. There is no perceptible direction of flow along this drainage ditch. The southem drainage ditch flows west along the site boundary until if ineets the junction of the east and west branches of Mill Creek. This ditch is 2 to 4 feet wide and 2 feet deep, and is heavily clogged with aquatic vegetation resembling algae. None of the drainage ditches identified in the site appeared to provide suitable fish habitat, although degraded channels may still provide hatiitais for lisfed and sensiUiive salmonids. None of the drainage ditches are mapped in King County Gl3 data. Because of their hydrologic connection to Mill Creek, all drainage difches on the site are presumed to be frsh-bearing.

Subject Changes to tlie Ctiristopher to 51 st Mitigation Plan From, Kim Anderson, Project Manager Date January 31, 2011 This memorandum addresses changes #o PSE's Proposed Christopherto 51"t Transmission Line Wetland ImpactAssessment and Mitigation P/an'in response to comments from the City of Aubum (City) on January 14, 2011. These changes are reguired for submittals in advance of the Conditional Use Permit public hearing. AECOM responded to the following comments from the City: • Please revise the conceptual mitigation plan to include willow trees as recommended by the Muckleshoot Indian Tribe. Recommendations by the Muckleshoot Indian Tribe include modifying the planting plan for Wetland C by replacing many of the proposed shrub species with native willow species; modifying the planting plan for Wetland E wetland.areas (E1 and E2) by planting native conifers (or native willow species if the powerline location precludes the use of conifers) instead of the proposed natNe shrubs; and modifying tFie Wetland E buffer area (BE-1) by replacing many of the proposed shrub species with nafive willow species: AECOM has revised the planting plans for Wetlands C and E to address concems by the Muckleshoot Indian Tribe: Plantings in these wettands were revised to subsfitute a total of 192 willows for other shrubs identified in the planting plans. The changes can be seen in Table 4-3 of the revised mitigation report, as - well as in the planting plans provided in Appendix C. Because of height restrictions under transmissions lines (25 feet under 115-kV lines), the only native willow suita6le for planting in the wetland areas'at Wetlands C and E is Sitka willow (Salix sitchensis). Sitka willow.is. the most prevalent willow in wetlands in the South Puget.Sound Region, roots well, and typically has a high survival rate. It grows well in saturated to moist soils, and is compafible with overhead lines up to 155 kV. The planting plan at Wetland C was modfied to include 124 Sitka willows. However, many of'the native shrubs originally proposed were retained in order to encourage a diversity of native plants in the wetland. In planting areas E-1 and E-2 at Wetland E, conifer species are not suitable substitufions, as there are no nafive conifer species that meet the 25-fo6t height restnction. Although no transmission lines run through this area presently, PSE must keep options open for further ezpansion, and transmission lines may need to be run through this area in the future. The wetland C planfing plans were modified to include 34 Sitka willows in each ptanfing area (E-1 and E-2), for a total of 68 willows at the mitigation site. Many of the To enhanceand sustain the world's buitt, natural and social environmerrts AECOM 2 : native shrubs originally proposed were retained in order to encourage a diversity of native plants in the wetland. PSE is unable to revise the planting plan for the buffer area in Wetland E to include natiye willows. The only native willow that might survive in this upland buffer area is Scouler's willow (Salix scou/eriana), which exceeds the height restrictions for overhead power lines. The BE-1 buffer planting area consists of disturlied; non-native soils, including areas of rip-rap and other fill. Stabilitjr does not appear to be a concem along the artificial 6ank in this area, and planfings may be difficult where rip-rap is present. . " However, the native shrub species seleeted will provide some shade funetions. e Please revise the stream and wetland addendum; dated July 2010, that the drainage ditches would be defned as streams and subject to the requirements of Aubucn City Code Chapter, -16.10 if they are presumed fo be used by salmonids: Please revise this discussion in the addendum document. AECOM has revised the Christopher Substation to 51 st Avenue South Wetland Delineation and Stream Assessment (page 3) to reflect the requested changes.

ICE File No. 0109-031 INTRODUC'II'ION T'his critical area report presents .the results of Icicle Creek Engineers' (ICE's) geotechnical engineering services regazding the clearing (tree removal) of a Puget Sound Energy (PSE) proposed West Christopher Transmission line right-of-way (ROV1) where the alignment cibsses a steep slope bordering the west side of the Green River valley in Auburn, Washington. Our services were xequested by Heather Brickey of PSE on May 5, 2008 and were. completed in general accordance with our Confuming Agreement dated May 7, 2008. Ms. Brickey provided ICE with the following informaUon regazding the ROW: o PSE; April 2, 2008, "West Christopher Transmission ROW," aerial photograph image showing the proposed transmission line alignment, scale 1 inch = 0.1 mile. The portion of the ROW subject to this report includes about a%z-mile-long segment extending southeasf from West Valley Highway North to the top ofa slope (the east-facing slope of the Green River valley). The current ROW in this segment is primarily undeveloped and partially forested. The ROW will be-cleared of lazge trees .for the proposed transmission lines. Based on_information providedby Ms. Brickey of PSE;, portions of this segment of ROW are within "Environmentally. Sensitive Areas" (Landslide arid Erosion Hazard Areas) according to.City of Auburn Municipal Code: For this reason, a, _ geotechnical report (critical area report) is required to evaluate the potential effects of tree removal with" regard to potential slope stability and erosion impacts. The study area is shown relative to the surrounding area on the Vicinity -Map, Figure 1. The study area, including the ROW; is shown on the Site Plan, Figure 2. ' SCOPE OF SERVICES The purpose of our services was to complete a geological and geotechnical review of the ROW segment that crosses the Landslide and Erosion Hazard Area as a basis for evaluating the potential impacts to slope stability and erosion as it relates to the planned tree removal. Specifically, our scope of services included the following: 29335 NE 20th Street o Carnation, Washington 98014 e wwuv.iciclecreekengineers.com o(425) 333-0093 phone o(425) 996-4036 fax Heather Brickey Puget Sound Energy May 30, 2008 Page 2 im Review in-house files and geologic data with respect to subsurface conditions expected at the study area .•Complete a detailed geologic reconnaissance of the steep slope areas where the tree removal will occur including observation of vegetation types, springs and seepage, and evidence of landsliding. . • Evaluate the.stability of the steep slopes regarding the potential effects (slope stability and erosion) associated with the removal of trees. ~ Provide recommendations for tree removal associated with. erosion control practices to reduce landslide and erosion potential, as needed. , - ENVIRONMENTALLY SENSITIVE AREAS DESCRIPTION I;ANDSLYDE HAZARD AREAS - ' _ Auburn Municipal Code (AMC December 7, 2007), Chapter 16.10.20 defines a Landslide . Hazatd Area as areas that, due to a combination of slope inclindtion, relative soil permeability, and hydrologic conditions are susceptible to varying degrees of risk of landsliding. Landslide hazard areas are classified as Classes I through IV based on the degree of risk as follows: 1. Class I/Low Hazard. Areas with `slopesof 15 perce'nt or less. 2. Class IUModerate Hazard. Areas with slopes of behveen 15 percent and 40 percent and that are underlain by soils that consist largely of sand, gravel or gdacial till. . 3, Class III/High Hazard. Areas'with slopes between 15 percent and 40 percent that are underlain by soils consisting largely of silt and clay. . 4. Class N/Yery High Hazard. Areas with slopes steeper than 15 percent with identifiable zones of , • emergent wate'r (e.g:; "springs'or ground water seepage), areas of identifiable landslide deposits regardless of slope and all areas sloping more steeply than 40 percent. " Land alteration, including clearing (tree removal), is generally prohibited in Class IV Landslide Hazard Areas (AMC 16.10.100), though subject to "Special Exception for Public Agencies and Utilities" as described in AMC 16.10.170: EROSION giAZARD AREAS AMC Chapter.1b.10.20 defines an Erosion Hazard Area as- areas underlain by soils identified by the U.S. Department ofAgriculture Soil Conservation Service (SCS), now knotivn as the Natural Resource Conservation Seryice, as having "severe " or "very severe " erosion hazards. This includes the following group of soils when they occur-on slopes of75 percent or greater: -Alderwood- Kitsap (AkF);' Alderwood gravelly sandy loam. (AgD), Kitsap' silf loam (KpD), Everett (EvD), and Indianola (InD). " The City of. Auburn may approve and condition proposals for the alteration of Erosion Hazard Areas based on the degree to which the significant risks posed to public and private properiy and to public health and safety can be mitigated. GEOLOGIC SETTING _ The geology of the study area has.:been mapped by the U.S. Geological Survey (USGS - Geologic Map of the Poverty Bay. 7.5 Afinute Quadrangle, King and Pierce County Washington, " Scienrific Investigations Map 2854, dated 2004) as "pre-Fraser sediments" consisting of glacially , overridden glacial and nonglacial soils described as sand, gravel and.silt (lakebed).sediments containing locally overconsolidated peat layers. These soil conditions aze consistent with our site observations in soil exposures (primarily road cuts and overtumed tree root wads) within and neaz the study area. Icicle Creek Engineers 0109031/053008 • . Heather Brickey Puget Sound Energy May 30, 2008 Page 3 Weathered soils have developed over the narive soils by natural weathering processes. The weathered soils are expected to be about 5-feet thick and are in a loose to medium de.nse or soft to ,.::inedium stiff condition because of weathering _ processes (animal burrowing, root . bioturbation, wetting/drying and freeze/thaw cycles). _ No landslides have been mapped by the USGS within or adjacent (within 500 feet) to the study area. SCS SOIL CONDITIONS The surficial soils of the study area have. been mapped by the U.S. Department of Agriculture, Soil Conservation Service (SCS, November 1973,:_`.`Soil Survey, King County Area, Washington"). According to this soils mapping, the sloping portions of the steep slope area of tlie site are underlain by ."Alderwood" series soils referred to as "AgC" (on slopes more than15 percent: grade) and "AkF" (on slopes more than 25 percent grade). AgC and AkF are described by the SCS as having a severe erosion hazar.d and very severe erosion hazard potential, respectively. SITE CONDITIONS GENERAL Matt Kogle ofICE completed a surface reconnaissance of the study area.on May 16; 2008. As previously described, the ROW crosses an undeveloped, partially forested area,. bordered by similar undeveloped properties. However, existing utility easements including Bonneville Power Administration (BPA) transmission line and other underground utilities are located south of the;ROW. The ROW Had been field surveyed with a path cleared prior to our, site; this clearing facilitated ~our,access conditions and ROW location.,accuracy. We also observed 1he adjacent azea with emphasis on the existing BPA and other utility easements south of the ROW. ' . TOPOGRAPHY . , The ROW crosses the study area in a ri sing traverse of an. east-facing hillside overlooking the Green River valley. From West Valley Highway North at about Elevation 90 feet, the ROW traverses . slopes (steep slopes) that generally exceed 40 percent grade to intersect with the nearly level'upland area at about. Elevation 300 feet. The steep slope areas are typically even-surfaced with no stieam valleys or swales observed along the ROW. Locally, less steep areas exist along the ROW, in particulaz a narrow bench at about Elevatiori 115 feet near West Valley Highway North: A second; much smaller and . mod.erately sloping bench, occurs at about Elevation 175 feet near the midpoint of the ROW in`tHe study area. Slopes along the ROW based on regional topographic mapping are shown on the Slope Map, Rigure 3. The eacisting.BPA and other utility easements south of the ROW traverse similaz temain, though the slopes aze somewhat less steep (less than 40 percent grade) in these areas. SOILS Based on our observations of surficial soil exposures within the study area, it appears the native soils consist of glacially: overridden sand with variable amounts of silt and gravel (pre-Fraser sediments), , consistent with regional mapping by the USGS. . Weathered soils mantle:ihe grourid surface in a layer up : , . to.5-feet-thick and consist of silty sand with variable amounts of gravel and, roots, generally consistent witti regional mapping by the SCS. - Icicle Creek Engineers 0109031/053008 Heather Brickey Puget Sound Energ,y May 30, 2008 Page 4 VEGETATION AND SITE USE The ROW is generally vegetated with mature, second-growth deciduous and evergreen trees. Truck diameters of the trees range up to,36 inches. Most of the-trees have straight trunks (near vertical) though some exhibit "butt-bow" which i$ caused by "soil creep". on steep slopes. Soil creep occurs where the swficial layer of soil (weathered. soil) "moves" or "creeps" downslope as a result of weathering processes (freeze-thaw, wetting-drying, etc). Soil creep is a natural downhill soil movement condition on most steep slope areas and is measured in terms of less than a millimeter per-yeaz. In'the lower portion of the ROW (from about Elevation 120 to 170 feet), we observed that there were less trees. The ROW presently contains a moderately dense to dense understory of brush., ' As previously described, the ROW primarily crosses an undeveloped, partially forested area However, on the narrow bench near West Valley Highway Nortti,_ the ROW crosses a driveway that accesses structures north and south of the ROW at this location SPRINGS AND SEEPAGE We did not observe surface water, including springs. and seepage, within the ROW. SLOPE STABILITY AND EROSION ~ We did not observe surface evidence of slope instability within or adjacent to the ROW, including the BPA and other utility easements to the south. Slope instability is typically manifested by uneven topography, baze soils scarps, and groups of.leaning or toppled trees, . We did not observe evidence of erosion within the ROW. We did observe local azeas of erosion (gullying) in the BPA and other utility easements to the south. Some of this erosion had been partially mitigated .by placement of quarry spalls., Other areas of erosion appeared to result from the lack of proper erosion control measures and infrequent maintenance. None of these erosion occurrences observed appeared to be causing significant damage. CONCLUSIONS The ROW crosses several thousand feet of Class IV Landslide and Erosion Hazaid Areas as shown on Figures 4 and 5. Because of the Class IV Landslide Hazazd Area.designation (the slopes are inclined more than 40 percent grade), PSE should request a"Special Exception for Public Agencies and Utilities" in order to alter (tree clearing) the 200-foot ROW within the Class IV Landslide Hazard Area. In our opinion, the removal of trees may be completed without adverse impacts to the stability of the steep slopes or erosion, provided that recommendations in this report are implemented. The na.tive soils (pre-Fraser sediments) are not particularly susceptible to landsliding or adverse erosion. However, the surficial weathered soils that mantle the ground surface are typically not, as dense as the native soils " and_ can be susceptible to shallow landsliding and erosion, if not mitigated. Based on ow observations of the BPA and other utility easements to the south, similar land clearing (tree cutting) has occurred with no significant impacts with regard to slope stability and erosion. RECOMMENDATIONS Mirigation measures for Landslide and Erosion Hazard Areas aze directly related. Often, a landslide problem begins as an erosion problem. Focusing on mitigating erosion potential has the benefit of reducing landslide potential. For this reason, our recommendations are directed primarily at reducing erosion potential with respect to tree cutting in the ROW. We recommend the following tree removal practices to reduce the potential for post-tree removal landslides and erosion. _ Ic'icle Creek Engineers 0109031/053008 Heather Brickey Puget Sound Energy May 30; 2008 Page 5 o Cut tree stumps and root mats should be left in place. . e Brush and nonhazardous trees should not be cut to the extent this is practical. .o Tree removal in the C1ass.IV Landslide Hazard Areas should be completed by hand.carcying in small pieces or suspension cable systems, such. that dragging of the cut . tree across the natural ground surface is reduced. e; Small limbs and tree trunks may be left on the steep slope areas provided they are cut into pieces (no more than 10-feet long), and scattered on the ground surface. However, the larger trees will generate a considerable amount of woody debris and most of this material should.be removed as "scattering" of this material may not be practical. • Excessive disturbance to the ground surface; such as rutting caused by tree removal, should be . repaired using.hand tools and covered with an appropriate ground cover (e:g:, straw mulch or other appropriate erosion controT products). - e Tree cutting and the, installation of erosion control measures should be observed by a representative from our _firm to evaluate the effectiveness of erosion control measures installed and to provide additional`recommendations, as.needed. e. The ROW should be replanted with suitable tree seedlings, if appropriate, within one year following the tree removal in accordance with an approved vegetation managemenf plan. e Temporary road access and/or transmission line: structures (such as monopoles)• should, be further - evaluated for geotechnical recommenda.tions depending on the location of these features (not known at this time) to reduce impacts to slope stabilify and erosion. . _ USE OF THIS REPORT We have prepared this report for use by PSE.~ Our report, conclusions and interpretations should not be construed as a warranty of the site conditions.

Based on our review of the January 2010 Auburn review comments letter, Item 5 on page 3 lists details relating to geotechnical issues. To address these review comments, we have restated the comriient followed . by our response as presented below. AUBURN fiTEM 5 . A number o, f studies have shown that depending on species and age, mature trees haverainfall interception volumes between 300 and 2, 000+ gallons per tree per year. This suggests that depending on species and age of the trees; removal of up to 700 trees could result in significant amount of additional water entering the soil as d result of increased througlifdll (precipatataon hitting the ground) in the proposed transmissaon corridor. ICE RESPONSE We are not familiar with the atudies related to tree rainfall interception, but the volumes seem reasonable. However, it is likely tliat the trees aze mosteffective in rainfall interception when leafed out. It is likely that this rainfall,interception is not as effective during the winter months when the lea.ves are off of the trees Equally importanf is raindrop impact on the ground surface during the winter months as tlus has been shown to increase the erosion potential.

Methods to accomplish topsoil and vegetation preservation are presented in ICE's May 2008 report. We expect the native grasses and brush will quickly flourish as a result of the tree cutting. "The topsoil layer along with vegetation, if preserved as recommended, should protect the sife from erosion and slow runoff similar to tha.t of the existing condition during the winter months. AUBURN ITEM 5= 2°a BULLET Please identify what impacts the infzltration and runoff of more waterfrom precipitation throughfall will have on groundsaturation, erosion, andslope stability, particularly in theportions of the corridor that meet A CC Chapter 16.10 definition of landslide hazard and/or erosion hazard, and what measures are proposed to address such impacts. ICE RESPONSE Provided that PSE implements the recommendations for mitigation as stated in our May 2008 report, we expect that increased runoff will be negligible. Preservation of the existing topsoil and ground cover vegeta.tion is essential for effective runoff absorption. As a further note, mature trees can often become unstable on. slopes resulting in tree falls that cause other trees to fall. in a domino effect. In our opinion, based on our experience, brushy, healthy immature trees,'low growing mature trees and brush are more effective at reducing natural erosion and enhancing slope stability than areas vegetated with mature trees susceptible to falling and shading out ground cover. AUBURN ITEM 5- 3`d BULLET A stormwater analysis should evaluate the likely magnitude of increased stormwater runoffflows as a result of the removal of, and long term change in vegetation, and that such stornnvater impacts can be satisfacforily mitigated by theproposal. The downstream analysis should evaluate how any irtcreases in stormwater flows will affect flows in Mudlen Slough Tributary 00053. ~ ICE RESPONSE A short term goal of this pro;ject is to use proper tree cutting and removal methods, along with prompt . replanting witli appropriate vegetation such that potential impacts to Mullen Slough Tributary 00053 are reduced to an acceptable level. Provided that proper tree removal methods are used as described in.ICE's May 2008 report, the, undisturbed topsoil and ground vegetation should proyide adequa.te absorption of rainfall. The long.term goal of this project is to reestablish the existing conditions with proper plantings that are appropriat"e within a. powerline corridor, a.nd also have the added benefits of rainfall and raindrop interceprion and dense root mat_ distribution. As previously described, the preservation of the existing topsoil - and vegeta.tion is essential for effective runoff absorption. Stormwater analysis would likely inyolve the use of the "Rational Method" for the evaluation of runoff, . Based on the ground cover types before and after tree removal, the runoff coefficient, would still fall within the range of "Forest" which ranges from 0.05 to 0.25. No other ground cover type (Lawn, Meadow, Pasfure, . Culrivated Land) is reasonable to use for this situation. Other than the removal of trees, which have limited rainfall interception capacity during the winter months, the ground conditions (topsoil and ground vegetation) remain the same, provided that the recommendafions presented in ICE's May 2008 report are implemented.

AECOM Report Environment i :i/egetation Management P9an Christopher Substatoon to 51st Avenue South Transmission Line Project , Vegetatlon Management Plan July 2010 AECOM Report Environment ~ introduction This vegetation management plan (plan) address vegetation management activities associated with Ruget Sound Energy`s (PSE's) proposed Christopher Substation to 515t Avenue South Transmission Line Project. The proposed transmission line corridor is approximately 1:5 miles long, and inclu,des areas that are classified as Landslide Haiard Areas and Erosion Hazard Areas by the City of Auburn Municipal Code. According to a geotechnical report completed for the project site (Icicle Creek Engineers 2008; inc.luded as an appendix to this report) a vegetation management plan is required for _ the Landslide and Erosion Hazard areas to reduce the potential for la,ndslides and erosion as a result of project activities. . ' Project Overview - The proposed project corridor is located in Sections 1, 2, 3, 10, 11, and 12 ofTownship 21 North, Range 4 East, within the City ofiAu6um, in King County, Washington.The proposed 115-kV transmission lines will tie into the Christopher Substation on the eastern end of the proposed project corridor, and into . existing lines at 51s` Avenue South on. the western end. Along most of its lengfh, the corridor has a width of 200 feet; however, the width is reduced to 100 feet as it approaches the substation. The total area covered by the proposed project corridor is approximately 33 acres (13 hectares). . The proposed project will entail placement of transmission line poles along the project corridor, and installation of three 115-kV transmission:lines. To provide clearance for the lines, approximately 700 , trees will be removed from the transmission line corridor. Numerous transmissiori line poles will be located along the projecf corridor: Each pole installation will require the augering of a hole 3 feet in diameter and 8.5 to 11.5 feet deep; depending on the pole height: Following ;pole placement, holes .will be backfilled with gravel and spoils will be hauled offsite or spread around the base of the,pole. Project-Related Vegetation Management • To proyide: clearance for the transmission lines and minimize the need for future maintenance of the - comdor, PSE will cut trees with the potential to interFere with or fall into the lines. The goal of tree removal in transmission line corridors is to remoye Iarge, problem tree species and develop lower- growth-form plant communities composed of low-growing shrubs and small-scale trees. The maximum height of plants in 115-kV transmission line righfs-of-way (ROWs) is 25 feet. PSE has identified all of the treeswithin the project corridor that will need to be removed. Areas that are densely populated with trees comprise a total area of about 3;700 feet 6y 100 feet, with additional clearing of sporadic individual or small groups of frees.. The trees to be cleared mainly consist of ~second=growth westem redcedars, red alders, black cottonwoods, Douglas-firs, maples, western hemlocks, and pines, with an occasional.fruit and ornamental tree: Tree removal activities will be ground-based and will generally utilize meehanize.d equipment. Some trees along the edge of the corridor may only require trimming. In wetlands and wetland/stteam buffers, special precautions will be taken, including hand removal near $treams; felling merchantable trees - ' toward the outside of wetlands so they can be picked up using mechanized equipment to achieve at least single-end suspension; and confining use of'mechanized equipment to existing access roads or timber/composite mats: Vegetatfon Management Plan July 2010 . AECOM Report Environment 2 Project-Related Disturbance in Landslide Hazard and Erosion Hazard Areas According to the geotechnical report, the projeet eorridor crosses several thousand feef of Class IV Landslide Hazarci Areas and Erosion Hazartl Areas (see the geotechnical report in Appendix A for figures). Class IV Landslide Hazard Areas are defined as Very High Hazard areas, with slopes steeper than 15 percent with identifiable zones of emergent water, areas of identifiable landslide deposits , regardless of slope, or all areas sloping more steeply than 40 percent The identified areas in the project corridoc meet this definition because they are inclined more than 40 percent. Withirr the steep slope area, dominant tree species include Douglas-fir anii red alder, with lesser . amounts of bigleaf maple and westem hemlock. A detailed summary of trees that have been identified for removal is provided in Table 1. Table 1. Trees Idenffied for Removal Within Landslide and Erosion Hazard Area.

Tree removal activities in the steep slope area will be scheduled during dry months. Some of the trees slated for removal will by access at the base of the hill, using a"Slashbuster" and/or rubber-tired skidder to cut down and load trees onto log trucks fo.r removal: Slash may be moWed on site at the base of the hill, .The rest of the trees will be accessed from the top of the slope using a tower logging method and some hand removals using standard choker: setting techniques. Slash may be bucked up by hand and lopped and scattered as large woody debris: In accordance with the recommendations of the Vegetation Managemem Plan July 2010 AECOM. Report Environment g geotechnical report, during tree removal activities, the following pracfices will be impiemented within tlie Landslide and Erosion Hazard area: o Cut tree stumps and root mats will be left in place. a To the extent practical, brush and nonhazardous trees will not be cut. a Tree removal will be completed by hand carrying in small pieces or suspension cable-systems, such that dragging of the cut tree across the natural ground surface is reduced. s Any small limbs and tree trunks left qn the ground will be cut into pieces no more than 10 feet long and scattered. Larger trees will be removed. e Excessive disturbance to the ground surface, such as rutting caused by tree removal, should be repaired using hand tools and covered with an appropriate ground cover (e.g., straw mulch or other appropriate erosion control products). ' o Tree cutting and installation of erosion control measures should be obsenred to evaluate the e.ffectiveness of erosion control measures installed and to provide additional recommendations, as needed. ' Replanting of Cleared Areas Although cuf tree stumps and root mats will be left in place, planting replacement vegetation is necessary to retain ongoing slope stabilityin the :area. It.is assumed tFiaf existing sh.rubs in the area , - would fill in some gaps created during clearing. activities. However, additional plantings are necessary to ensure stability of slopes once the root masses left behind begin to decay and lose their ability to bind soil.. , The planting plan presented in Table 2 is recommended for the steepslope area. This plan mitigates for tree removal by planting one shrub or small tree for every tree less than 20 inches dbh that will be removed; and three shrubs or small tree for every tree 20 inches dbh or greater that will be removed. Goals, Objectives, and Performance Standards The project objectives are to provide a native shrub communities that replace the soil stabilizing characteristics of the existing forested communities on the site. This is to be accomplished by planting " approximately450 na6ve shrubs and small trees in the steep slope areas affected by tree removal activities. In Year 1, survival of installed native shrubs will be 100 percent. If all dead plantings are replaced, the standard will be considered met. In Year 3, survival of installed shrubs within ttie steep slope area will be 85 percent or greater. VegetaUon ManagemeM Plan July 2010 AECOM Report Environment 4 Table 2.

Right-of-Way , Aubum, Washington ICE File No. 0109-031 INTRODUCTION ' This critical area report presents the results of Icicle . Creek Engineers' (ICE's) geotechnical engineering services regarding the clearing (tree removal) ofa Puget Sound Energy (PSE) proposed West ~ Chri'stopher Transmission line right-of-way (ROW) where the aligriment crosses a steep slope bordering the west side of.the Green River valley in Auburn, Washington. Our services were requested by Heather Brickey of PSE on May 5, 2008 and were completed in general accordance with our Confirming Agreement dated May 7, 2008. Ms. Brickey provided ICE with the following information regarding the ROW: • PSE, April 2, 2008, "West Christopher Transmission ROW;" aerial photograph image showing the proposed transmission line alignment, scale 1 inch = 0.1 mile: The portion of the ROW subject to this report includes about a'h-mile-long segment extending southeast from West Valley Highway North to the top of a slope (the east-facing slope of the Green River valley). The cuirent ROW in this segment is primarily undeveloped and partially forested. The ROW will be cleared of large trees for the proposed transmission lines. Based on information provided by Ms. Brickey of PSE, portions of this segment of ROW are within "Environmentally Sensitive Areas" (Landslide and Erosion Hazard Areas) according to City of Aubum Municipal Code. For this reason, a geotechnical report (critical area report) is required to evaluate the. potential effects of tree removal with regard to potential slope stability and erosion impacts. ' The study area is shown relative to the surrounding area on the Vicinity Map, Figure 1. The ' study area, including the ROW, is shown on_ the Site Plan, Figure 2. SCOPE OF SERVICES The purpose of our services was to complete a geological and geotechnical review of the ROW segmerit that crosses the Landslide and Erosion Hazard Area as a basis for evaluating the potential impacts to slope stability and erosion as it relates to the planned tree removal. Specifically, our scope of services included the following: 29335 NE 20th Street e Carnation, Washington 98014 • www.iciclecreekengineers.com .(425) 333-4093 phone o(425) 996-4036 fax • Heather Brickey . Puget Sound Energy May 30, 2008 Page 2 v Review in-house files and geologic data with respect to subsurface conditions expected at the study area. • Complete a detailed geologic reconnaissance of the steep slope areas where the tree removal will occur including observation of vegetation types, springs and seepage, and evidence of landsliding. m Evaluate the stability of.the steep slopes regarding the potential effects (slope stability and erosion) associated .with the removal of trees. m Provide recommendations for tree removal associated with erosion control practices to reduce landslide and erosion potential, as needed. ~ ENVIRONMENTAL,Y.,Y SENSITIVE AREAS DESCRIPTION Y.ANIDSI.IDE HAZARD AREAS Auburn Municipal Code (AMC. - December 7, 2007), Chapter 16.10.20 defines a Landslide Hazazd Area as areas tlaat, due to a combination of slope inclination, relative soil perineability, and , hydrologic conditions are susceptible to vgrying degrees of risk of landsliding. Landslide hazard areas are class f ed as Classes I through IV based on tlie degree of risk as follows: 1. Class I/Low Hazard. Areas with slopes of 15 percent or less. 2. Class II/Moderate Hazard. Areas with slopes of between 15 percent and 40 percent and that are _ underlain by soils that consist largely of sand, gravel or glacial ti1L . , - 3. Class III/High Hazard. Areas with slopes between 15 percent and 40 percent that are underlain,by . soils consisting largely of silt and clay. 4. Class IY/Very High Hazard. Areas with slopes steeper tJzan IS percent with identifzable zones, of emer"gent water (e.g., springs or ground water seepage), areas of identifiable landslide deposits regardless of slope and all areas sloping more steeply than 40 percent. " Land alteration, including clearing (tree removal), is generally prohibited in Class IV Landslide Hazard Areas (AMC 16.10.100), though subject to "Special Exception for Public Agencies and Utilities" as described in AMC 16.10.170. EROSION FIAZARD AREAS AMC Chapter 16.10.20 defines an Erosion Hazard Area as areas underlain by soils " identifzed by the U.S. Department of Agriculture Soid Conservation Service (SCS), now known as the Natural Resource Conservation Service, as having "severe" or "very severe" erosion hazards. This includes the following group of soils when they occur on slopes of 15 percent or greater: Alderwood- Kitsap (AkF), Alderwood gravelly sandy loam (AgD), Kitsap silt loam (KpD), Everett (EvD), and Indianola (InD). " The City of Auburn may approve and condition proposals for the alterafion of Erosion Hazard Areas based on the degree to which the significant risks posed to public and private property and to public health and safety can be mitigated. GEOLOGIC SETTING The geology of the study area has been mapped by the U.S. Geological Survey (LJSGS - "Geologic Map of the Poverty Bay 7.5 Minute Quadrangle, King and Pierce County, Washington," Scientific Investigations Map 2854, da.ted. 2004) as "pre-Fraser sediments" consisting of glacially overridden glacial and nonglacial soils described as sand, gravel and silt (lakebed) sediments containing locally overconsolidated peat layers. These soil conditions are consistent with our site observations in , soil exposures (primarily road cuts and overturned tree root wads) within and near the study area. Icicle Creek Engineers 0109031/053008 • Heather Brickey • Puget Sound Energy May 30, 2008 Page 3 Weathered soils have developed over the native soils by natural weathering processes. The weathered soils are ezpected to be about 57feet thick and are in a' loose to medium dense or soft to . ' medium stiff condition because of weathering processes (animal burrowing, root bioturbation, ~ wetting/drying and freeze/thaw cycles). No landslides have been mapped by the USGS within or adjacent (within 500 feet) to the study area. SCS SOIL CONDI'TIONS The surficial' ,soils of the study area have been mapped by the U.S. Department of Agriculture; Soil Conservation Service (SCS, November 1973, "Soil Survey, King County Area, Washington"): According to this soils mapping, the sloping portions of the steep slope area of the site are underlain by "Alderwood": series soils refened to as "AgC" (on slopes more than 15 percent grade) and "AkF" (on slopes more than 25 percent grade). ~AgC and AkF are described by the SCS as having a severe erosion hazard and very severe erosion hazard potential, respectively. _ SITE CONDITIONS . GENERAL Maft Kogle of ICE completed a surface reconnaissance of the study area on. May 16, 2008. As previously described, the ROW crosses an undeveloped, partially forested area, bordered by similar , undeveloped properties. However, existing utility easements including Bonneville Power Administration (BPA) iransmission line and other underground utilities are located south of the ROW. The ROW had . been field surveyed with a path cleared prior to our site; this clearing facilitated our access condirions and - ROW locarion accuracy. We also observed the adjacent area with emphasis on the existing BPA and . other utility easements south of the ROW. . 'I'OPO.GRAPHY . The ROW crosses the study area in a rising traverse of an east-facing hillside overlooking the Green River valley. From West Valley Highway North at about Elevation: 70 feet, the ROW traverses slopes (steep. slopes) that generally exceed 40 percent grade to intersect with the nearly level upland area at about Elevation 300 feet. The steep slope areas are typically even-surfaced with no stream valleys or swales observed along the ROW. Locally, less sfeep areas ezist along the ROW, in particular a narrow bench at about Elevation 115 feet near West Valley Highway North. A second, much smaller and moderately sloping bench, occurs at about Elevation 175 feet neaz the midpoint of the ROW in the study area. Slopes along the ROW based on regional topographic mapping are shown on the Slope Map, Figure 3. The existing BPA and other utility easements south of the ROW traverse similar terrain, though the slopes are somewhat less steep (less than 40 percent grade) in these azeas. SOILS Based on our observations of surficial soil exposures. within the study area, it appears the native soils consist of glacially overridden sand with variable amounts of silt and gravel (pre-Fraser sediments), , consistent with regional mapping by tYie USGS. Weathered soils mantle the ground surface in a layer up to 5-feet-thick and consist of silty sand with variable amounts of gravel and roots, generally consistent with regional mapping by the SCS. Icicle Creek Engineers 0109031/053008 • Heather Brickey Puget Sound Energy May 30, 2008 Page 4 VEGETA'I'ION AND SITE USE The ROW is generally vegetated with mature; second-growth deciduous and evergreen trees. Truck diameters' of the trees range iip to 36 inches. Most of the trees have straight trunks (near vertical) though some exhibit "butt-bow" which is caused by "soil creep" on steep slopes. Soil creep occurs where the surficial layer of soil (weathered soil) ".`moves" or "creeps" downslope as a result of weathering processes (freeze-thaw, wetting-drying, etc). Soil creep is a natural downhill soil movement condition on most steep slope azeas and is measured in terms of less than a millimeter per year. In the lower portion of the ROW (from `about Elevation 12010 170 feet), we observed that there were less trees. Tlie ROW presently contains a moderately dense to dense understory of brush: , As previously described, the ROW primarily crosses an undeveloped, partially forested area. However, on the narrow bench near West Valley Highway North, the. ROW crosses a driveway that accesses structures north and south of the ROW at this location. SPRINGS AND SEEPAGE _ We did not observe surface water, including springs and seepage, within the ROW. SLOPE STABILITY ANID EROSION We did not observe surface evidence of slope instability within or adjacent to the ROW, including the BPA and other utility easements to, the south. Slope instability is typically inanifested by uneven topography, bare soils scarps, and groups of leaning or toppled trees, We did not observe evidence of erosion within the ROW: We did observe local areas of erosion . (gullying) in the BPA and other utility easements to the south. Some of this erosion had been partially mitigated by placement of quarry spalls. Other areas of erosion appeazed to result from the lack of proper ' erosion control measures and infrequent maintenance. None of, these erosion occurrences observed appeared to be causing significant damage. CONCLUSIONS ' The ROW crosses several thousand feet of Class IV Landslide and Erosion Hazard Areas as shown. on Figures 4 and 5. Because of the Class IV Landslide Hazard Area designation (the slopes are , , inclined more than 40 percent grade), PSE should request a"Special Exception for Public Agencies and Utilities" in order to alter (tree clea;ing) the 200-foot ROW within the Class N Landslide Hazard Area. In our opinion, the removal of trees may be completed without adverse impacts to the stability of the steep slopes or erosion, provided that recommendations in this report aze implemented. The native soils (pre-Fraser sed'unents) are not particularly susceptible to landsliding or adverse erosion. However, the surficial weathered soils that mantle tfie ground surface are typically not as dense as the native soils - and can be susceptible to shallow landsliding and erosion, if not mitigated. Based on our observations of the BPA and other urility easements to the south, similar land clearing (tree cutting) has occurred with no significant impacts.with regard to slope stability and erosion. RECOMIVVIENDATIONS Mitigation measures for Landslide and Erosion Hazard Areas are directly related. Often, a- landslide problem begins as an erosion problem. Focusing on mifigating erosion potential has the benefit of reducing landslide potential. For this reason, our recommendations are directed primarily at reducing erosion potential .with respect to tree cutting in the ROW. We xecommend the following tree removal practices to reduce the potential for post-tree removal landslides and erosion. Icicle Creek Engineers 0109031/053008 • Heather Brickey Puget Sound Energy . May 30, 2008 , Page 5 • Cut tree stumps and root mats should:be left in place. m Brush and nonhazardous trees should not be cut to the extent this is practical. e Tree removal in the Class N Landslide Hazard Areas should be completed by hand carrying in small pieces or suspension cable systems, such that dragging of the cut tree across the natural ground surface is reduced. m Small limbs and tree trunks may be left on the steep slope areas provided they are cut into pieces (no more than 10-feet long) and scattered on the.ground surface. However, the larger trees will generate a considerable amount of woody debris and most of this material should be removed as "scattering" of this material may not be practical. ' o Excessive disfurbance to the ground' surface, such as rutting caused by tree removal, sho "u,ld be repaired using hand tools and covered with an appropriate ground cover (e.g., straw mulch or other appropriate erosion control products). . . m Tree cutting and the installation. of erosion control measures should be observed by a representative. from our firm to evaluate the effectiveness of erosion control measures installed and to provid'e additional recommendations, as needed. o The ROW should be replanted with suitable tree seedlings, if appropriate, within one year following . the tree removal in 'accordance witli an approved vegetation management plan. m Temporary road access and/or transmission line structures (such as monopoles) should be further evaluated for geotechnical recominendations depending on tlie location of these features (not known at this time) to reduce impacts to slope stability and erosion.

Reliability'Project. The project invoTves :construction of four, 115 kV transmission lines originating from Puget'Power's Christopher Substation in-Auburn. The lines will travel west, para11e1 to:and north of existing BPA transmission lines, for approximately one mile. The lines then-separ.ate and continue, providing power to several customer bases in Southwest King County. At a recent pre-application conference with King County, we introduced the project and presented a preliminary erivironmental assessment of the trarismission line routes. The environmental assessment for the portion of the project in Auburn identified Mill Creek and its associated wetlands within the route. At this time, we would like to meet with City staff to not only . introduce the Christopher West Reliability Projeet, but to ask the City's assistance in identifying the level of detail which may be required to support Puget Power's permitting efforts in Auburn. In particular, we would like to focus the discussion on coordinated intergovernmental SEPA review among Auburn, Ring County, and Federal Way.'.We would also like information about Auburn permits which_may be appli:cable to this project. Please note this project is distinct from the'Christopher Substation expansion proposal. Please contact me (939-4343'), at your convenience to confirm a date for the Christopher West Reliability Project introductory meeting.

Tt was determined i-n 1978-79. that. ..we.shoul d begin deslg.n work on thfs project becanse of the growing%electrical load demand -tn the Auburn-Federa-l Way ar.ea: In add7tion, tFris facl7ity wou7d provide a backup source for ou-r present tyians- mission substatiorrs in,case of' outages. fihis ~ae7Tity wo~uld also 6ec vm~ an integral~ part-of the NortFiwest Fower Gr.id to protect a.gainst outages orl-BPA's 230kV system. To adequately 'serve the area an. additionai 3I-acre .pa.r:ceT was purchased in 1979 for a future 500kV transmfssion su6s:tatYOn when th,e.load densYty. . in South King County reaches a ievel requiring a hfigher transm1sslon voltage. - In July 1979, the Git,y Copncfl. apprpyed 4 rezqne W-itfi. g.

RE: BPA Right-of-Way Joinf Use Proposal , Chrisfopher Wesf Reliability Project Dear Hugh: As paxt of a plan to meet the increasing demand for power in the south . ' King County area of Washington; Puget Power has initiated the " Christopher West Reliability Project. . This project includes the eonsixuetion of four 115 kV transmission lines from our existing Christopher Substation, locatecr just east of -the West Valley Freeway (SR167), to fihe wesf. Puget Power currently has righfis to an easement in this area of approximately 200 feet in width. This easement is Iocated immediately norfih of :BPA's existing lines from SR167 to 51st Avenue South (see aftached).. This easement was obtained several years ago in anficipation of this project but was not cleared or otherwise prepared,for construction. We are now in the early states of preparing documents to support our permitting and public involvement activities. During this effort, members of our . project feam felt it necessary to record, for fu{ure reference, our reasons for not pursuing an agreemerit with BPA for making jaint use of your right- _ of-way for this project and avoid additional impact in this area. As a result of these comments; we would like to request that BPA review the possibility of allowing Puge# Power to construct four additional 115 kV cireuits within your existing corridor.: Two of these circuits would need to run from Christopher Substation to 51st Avenue South. The remaining fwo circuits would also follow this route but continue wesf to SR99. 1 Puget Sound Po4ver & Cight Company P.O. Box 97034 Beilevue, WA 98009-9734 (206) 454-6363 Mr. Hugh Starkey .
