FINAL ENVIRONMENTAL IMPACT STATEMENT Northeast Auburn/Robertson Properties Special Area Plan Auburn, Washington City of Auburn, Washington July 30, 2004 Fact Sheet Fact Sheet Project Title Northeast Auburn/Robertson Properties Special Area Plan File Number SEP02-0008 Nature and Location of Proposal The planning area for the Northeast Auburn/Robertson Properties Special Area Plan is located east of Auburn Way North, west of the existing I Street NE right-ofway, south of South 277tHStreet, and north of 45th Street NE. The planning area consists of approximately 120 acres and encompasses several parcels, including the Valley 6 Drive-inTheater and adjacent parcels owned or proposed for acquisition by the Robertson Properties Group (RPG).The proposed plan would affect land use and development by establishing new Comprehensive Plan designations and zoning within the planning area and by establishing standards for development, including transportation, drainage, and site design.RPG proposes to redevelop its property with a mix of retail, office, and/ormultifamily residential uses. The RPG property consists of approximately 59.2acres within the planning area; in this environmental impact statement (EIS), this property is referred to as the Auburn Gateway project area. The Auburn Gateway project is evaluated in this EIS as a plannedaction under Revised Code of Washington (RCW) 43.21C.031.Implementation of the Northeast Auburn/RobertsonProperties Special Area Plan and Auburn Gateway proj ect would involve the development of new roads and utilities, surface parking, and stormwater detention facilities. The existing drive-intheater and other structures on the RPG property would be demolished. The proposed access to the Auburn Gateway project area is from the existing roadways of Auburn Way North, D Street NE, South 277th Street, and an extension of I Street NE that would reach South 277th Street. Theproject would be constructed in phases that could extend to approximately 16 years (through December 2020).n~p-/ -'01- 0192-/-OOOfinal feis.docNEAuburn/Robertson Properties FinalEIS i Special Area Plan Fact Sheet Proponent Robertson Properties Group Contact: Michael Dee, Director of Development 120 North Robertson Boulevard Los Angeles, California 90048-3102 Phone: 310-855-8324 Lead Agency and Responsible Official City of Auburn Paul Krauss, AICP Director, Department of Planning and Community Development 25 West Main Street Auburn, Washington 98001-4998 Phone: 253-931-3090 Contact: Jeff Dixon, Senior Planner Required Permits and Approvals City approvals associated with the Northeast Auburn/Robertson Properties Special Area Plan: Comprehensive Plan amendment: policies, map, and subarea plan adoption Zoning text and map amendment Planned action ordinance (for the Auburn Gateway project area) Design guidelines Right-ofway acquisition City approvals that might be required for development: Street dedication Street or utility line easement vacation Facility extension agreements Right-ofway use permits Lot boundary adjustment and/or subdivision Planned unit development Demolition permit Clearing and grading permit Building permit Shoreline permit Flood zone control permit Deviation from City standards tis~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Special Area Plan ii Final EIS Fact Sheet Other agency approvals: County Sewer extension and modification approval State National Pollutant Discharge Elimination System (NPDES) permit Washington Department of Ecology) Federal Federal Emergency Management Agency (FEMA) map amendment Section 404 permit (Clean Water Act) (U.S. Army Corps of Engineers) Section 401 permit (Clean Water Act) (Washington Department of Ecology) Endangered Species Act compliance (administered by issuing agency if federal permits are required) Contributors to the Environmental Impact Statement Herrera Environmental Consultants Document production Geology, soils, and seismic conditions Water resources Plants and animals Hazardous materials Land use Recreation Utilities and public services Heffron Transportation Transportation MFG, Inc.

The cost of the draft EIS is $31 for a printed copy or 4.50 for an electronic version (pdf format) on a compact disc. The cost ofthe final EIS is for a printed copy or $4.50 for an electronic version (pdf format} on a compact disc. Subsequent Environmental Review Subsequent environmental review is not anticipated for most actions covered under the planned action described in the EIS, because a planned action ordinance is expected to be adopted. Additional environmental review under the State Environmental Policy Act (SEPA) will be required for any action exceeding the thresholds analyzed for the planned action. Development of roadways outside the area covered in the planned action, including 49th Street NE to the east of the Auburn Gateway project area, will require additional SEPA review. In addition, any action involving the filling of wetlands may require the approval of the U.S. Army Corps of Engineers and may require additional environmental review under federal laws. It is also anticipated that detailed geotechnical analysis will be necessary before any grading permits can be approved, and that more specific studies of hazardous materials may be required in order to obtain approvals for the removal of structures and grading in some portions of the proj ect area. Background Studies and Available Data Background studies and data used for the preparation of the EIS are listed under References in Part 5 of the draft EIS and in Part 4 of this final EIS. The archaeological resources report and the data sheets for the transportation study prepared specifically for the EIS are available in the Planning and Community Development Department at Auburn City Hall, 25 West Main Street, during regular business hours. n~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Final EIS v Special Area Plan Contents Fact S eet .........................................................................................................................................1 Part 1-Summary Introduction l Relationship between Special Area Plan and the EIS ..............................................................4 Public Participation and Special Area Plan Adoption Process .................................................4 Summary of Alternatives Evaluated Alternative 1: Retail and Office ................................................................................................9 Alternative 2: Retail ..................................................................................................................9 Alternative 3: Retail and Residential ........................................................................................9 Preferred Alternative ................................................................................................................9 No-Action/Existing Zoning Alternative .................................................................................10 Summary of Impacts ......................................................................................................................11 Major Conclusions and Unresolved Issues ....................................................................................17 Traffic Circulation ..................................................................................................................17 Floodplain ...............................................................................................................................17 Stormwater Management ........................................................................................................18 Irreversible or Irretrievable Commitment of Resources ................................................................19 Part 2-Errata and Additional Analysis Errata ..............................................................................................................................................21 Preferred Alternative-Impacts and Mitigation ..............................................................................23 Geology, Soils, and Seismic Conditions .................................................................................23 Uater Resources .....................................................................................................................23 Plants and Animals .................................................................................................................24 Aesthetics 26 Utilities and Public Services ...................................................................................................26 Transportatlon .........................................................................................................................27 Impacts ..........................................................................................................................27 Mitigation ......................................................................................................................31 n~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Final EIS vii Special Area Plan Part 3-Reponses to Comments on the Draft EIS Comment Letters and Responses ...................................................................................................37 Letter #1-Sarah Blake, Washington Department of Ecology ..............................................37 Letter #2 -Meredith Redmon, King County Wastewater Treatment Division ......................39 Letter #3 -Gary Kreidt, King County Metro Transit .............................................................43 Letter #4 -Stephen Mullen, City of Kent ..............................................................................45 Letter #5 -

For this plan, the City has focused the study on approximately 120 acres of land (referred to in this environmental impact statement EIS) as the planning area). The planning area is bordered by Auburn VUay North, South 277thStreet, 45th Street NE, and the existing undeveloped right-ofwayof I Street NE (Figure 1).The planning effort for the Northeast Auburn/RobertsonProperties Special Area Plan project is being driven largely by the desire of Robertson Properties Group (RPG), one of the largest property holders in the area, to redevelop the Valley 6 Drive-inTheater complex and adjacent properties that it controls. RPG has named its proposal Auburn Gateway. A core area of RPG'sholdings together with other properties that RPG is considering acquiring or that could be developed cooperatively, totaling approximately 59.2acres within the planning area, has been defined in the EIS as the Auburn Gateway project area. The RPG proposal is to redevelop these properties with a mix of retail, office, and/ormultifamily residential uses. The boundaries of the planning area and the Auburn Gateway project area are shown in Figure 2.A draft special area plan is being published simultaneously with this final EIS and is evaluated as the Preferred Alternative. Implementation of the special area plan would include rezoning some properties and passing a planned action ordinance.The development proposed by RPG would not be allowed under current zoning; therefore, new zoning is being considered for portions of the planning area. The planning area is currently zoned as unclassified (UNC), heavy commercial (C3), and multifamily residential (R4).Changes in zoning and development standards would affect the types of land uses, the sizes of areas designated for various land uses, and the locations of land uses allowed on the properties.The proposed action would amend the zoning code to create a new zoning district titled C4 Mixed- UseDistrict. The new zoning would create amixed-usecommercial zone that would allow a range of uses similar to those allowed in the C3 zone, with some modifications to the allowable land uses and development standards. Because the new zone would allow both residential and commercial uses, some light manufacturing and automobile-orienteduses would be prohibited.A draft planned action ordinance pertaining to the Auburn Gateway project area is being developed. The planned action ordinance will include a list of mitigation measures and a set of design guidelines to be implemented in the Auburn Gateway project area as development under the plan proceeds.tis~ p-/ -'01-0192-/-OOOfinalfeis.docNE Auburn/RobertsonProperties Final EIS 1 Special Area Plan gZ00Z uangny :0002 sdeW ~soa8 sauaoyl :saoanos 0 No IN \ 3 c - o m ~ v E yI~ N ~ m o yey ^ ~ M ~ ~ ~ W ICIa-+ m i+'Y v" L ~ o ~ ~ O S~~ ~ f` R y~ V~ ~ ~ # O ~ d ~ ~ ~ ~ ~ ~ m ~ i J o°~~yseM a''aW _ Y c Q ]!5 ~11 ~ a.~ 1S1~Z ~ ~ ~ ~ H~~j F ~ ~ i~~ 1 ' T~ r~ ~ ~ . ~ 3~ y a,a ~ ~ ~ elnsiuua ~~41~ ii~ &Y ~ ddesaiN w ~ - - _ ~ ~ ~ o~~ . p V10~i y R 1; ~ ~ M O 11 ~ f~Ml 15 f x ti ~ O ~ ~ lIM 1N Mq~; ~I O si7~ ~ ~ hl w~~' . ~ ~ ~ 5 ~ A~ ~ ~ ~ I ~ ~ ~ r.., wa~a~ M~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ J ~5 ~ ~ tMMN l~ ~ ~ ~ ~ 6 ~ y 3.

Aerial map of the planning areafor the NEAuburn/Robertson Properties Part 1, Summary-Introduction Relationship between Special Area Plan and the EIS The EIS is being used to evaluate options for the special area plan and forms the basis for the development of specific policies, regulations, and land use decisions for this area. The planning effort and the EIS are intended to facilitate the approval of a planned action for the Auburn Gateway project area as provided for in the State Environmental Policy Act (SEPA), codified in Section 43.21 C.031 of the Revised Code of Washington (RCW). Planned action approval would limit the need for further environmental review for City approvals associated with the implementation of the Auburn Gateway projec~ The overall intent of the special area plan, zoning amendment, and planned action approval is to provide RPG some flexibility for responding to market conditions within a specified range of commercial and residential land uses. Under the RPG proposal, this range of uses could include up to 1.6 million square feet of office space, up to 720,000 square feet of retail space, and/or up to 500 multifamily residential units (and not to exceed 50 percent of the lot area). The project would be constructed in multiple phases over approximately 16 years. Public Participation and Special Area Plan Adoption Process The planning process for adopting a special area plan, establishing new zoning, and designating a planned action involves the public at several steps. The following list outlines the steps of the planning process, some of which have already been completed: The Northeast Auburn Special Plan Area was established in the City of Auburn Comprehensive Plan in 1995. On February 23, 2001, RPG requested the preparation of an EIS and submitted to the City of Auburn a proposal to rezone its property within the Northeast Auburn Special Plan Area. An initial public meeting was held November 21, 2002, to describe the RPG proposal and solicit input on issues to be addressed in the special area plan. RPG developed three alternative development scenarios for the Auburn Gateway project area that included the maximum amounts of office, retail, and residential uses that it anticipates could be constructed in the project area under a proposed new zoning designation. A public scoping meeting was held January 28, 2003, to identify potentially significant impacts that should be analyzed in the EIS. The scoping notice is provided in Appendix J of the draft EIS, and notes on tis~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Special Area Plan 4 Final EIS Part 1, Summary-Introduction subsequent modifications to the scope are provided in Part 4 of the draft EIS, under Scoping of the Environmental Impact Statement. RPG's proposed alternatives for the Auburn Gateway project, together with a No-Action/Existing Zoning Alternative are analyzed in the draft EIS. The EIS evaluates all potential significant adverse impacts due to the proposed development of the Auburn Gateway project area as a planned action, as required under SEPA. Public comments on the draft EIS were solicited at a public meeting held on February 12, 2004. The public meeting also included discussion of potential policy preferences for the special area plan. A draft special area plan has been developed as the Preferred Alternative for analysis in this final EIS. The special area plan establishes policies covering a range of allowable uses, preferred street alignments, stormwater and floodwater management policies, and urban design goals designed to address the potential impacts of development under the plan. This final EIS has been prepared to respond to public comments and to evaluate the Preferred Alternative. A draft planned action ordinance pertaining specifically to the Auburn Gateway project area has been prepared. This ordinance specifies the thresholds for the development covered under the planned action and the required mitigation measures for addressing the adverse impacts of the proposed development. The draft special area plan, a zoning amendment, and an amendment to the City ofAuburn Comprehensive Plan acknowledging the special area plan will be presented to the Auburn Planning Commission. Following a public hearing, the Planning Commission will forward a recommendation on the special area plan, zoning amendment, and Comprehensive Plan amendment to the Auburn City Council for consideration. Assuming that the planned action ordinance is adopted, the proponent then is allowed to proceed with all the necessary permit applications without further environmental review, provided that the development complies with the terms of the planned action ordinance. After the planned action approval, with each application for a grading permit, a building permit, a subdivision, or other City approval required for development, the City will first determine if tis~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Final EIS 5 Special Area Plan Part 1, Summary-Introduction the work related to the application is covered by the scope of the planned action. If the work is covered, the conditions of the planned action apply. If the work related to an application is determined to be outside the scope of development covered by the planned action ordinance, the proj ect will proceed through an environmental review as required for all other proj ects that require City approval. If the work related to an application is determined to be covered under the scope of the planned action, no further SEPA review is required. In some cases, the planned action ordinance may require additional engineering or other studies to confirm the EIS conclusions that adverse impacts of a specific design would be adequately mitigated. Unless the specific approval sought by RPG (such as a future subdivision or planned unit development) requires a separate appealable decision by the City, there is no further administrative appeal of the City's decision to approve (or deny) an application under the planned action ordinance. tis~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Special Area Plan 6 Final EIS Part 1, Summary-Summary of Alternatives Evaluated Summar of Alternatives EvaluatedY This EIS evaluates the potential impacts of the range of land uses proposed for the Auburn Gateway project area, along with possible options for vehicle access and circulation. The action alternatives represent combinations of land uses that could be constructed in the Auburn Gateway project area, encompassing the maximum development for each of the three general use categories proposed by RPG: retail, office, and multifamily residential. The final development in the Auburn Gateway project area may include any combination of these uses. The features of each alternative are summarized in Table 1. A Preferred Alternative for the special area plan was developed for this final EIS. The Preferred Alternative, which is similar to the action alternatives evaluated in the draft EIS, is described under the heading Preferred Alternative. Additional detail is provided in the draft special area plan, which is being published simultaneously with this final EIS. Development for retail and residential uses would occur in phases over an approximately 16-year period. The assumptions for phased development that were used for this analysis are provided in Appendix B of the draft EIS. Under all the alternatives, development in the portion of the planning area outside of the Auburn Gateway project area is expected to be in accordance with the existing zoning and would include multifamily residential development to the south and east and heavy commercial development to the west. Under all the alternatives, including the No-ActionlExisting Zoning Alternative, stormwater detention would be provided in surface ponds within the project area, although detailed plans have not yet been developed. Under all the alternatives, including the No-ActionlExisting Zoning Alternative, floodplain storage compensation would be accommodated primarily outside the boundaries of the project area by means of the Port of Seattle's wetland mitigation project. However, compensation may need to be accommodated within the project area during the initial phases of development if the Auburn Gateway project area is developed before the Port of Seattle prof ect is available for use as floodplain compensation. One purpose of the special area plan is to choose the best public road configuration to facilitate the development of all properties in the vicinity, including the mix of uses and densities shown in the action alternatives for the Auburn Gateway project area. Under all the alternatives, South 277thStreet would be widened and a pedestrian trail would be constructed along the south side.Also included in all the alternatives is the construction of a new east-weststreet and I Street NE from South 277th Streetto 45th Street NE. The draft EIS evaluated several vehicle access options that include various locations for I Street NE, the new east-west street, and signalization options on Auburn ~ Uay North. A preferred access option has been developed for this final EIS.Separate stormwater detention facilities for public roads would generally be required and could be provided in underground vaults or in surface ponds. The infrastructure constructed with the project, including roads, public stormwater detention facilities, and utilities, would be similar for all the action alternatives.tis~p-/ -' 01-0192-/-OOOfinalfeis.docNEAuburn/ Robertson PropertiesFinal EIS 7 Special Area Plan UII ~ ~ O iii . ~ ~ ~ p ~ ~ ~ U N U O O N U ~ Z ~ ~ i Z O ~ N ~ ~ ~ ~ ~ ~ ~ N ~ ~ ~ N ~ N U N ~ ~ O ~ ~ ~ ~ ~ ~ ~ 'd a ~ M M m o0 0~~~0 ~~O oar oo•~' OW •--~~a~ +~o ~a~~o ~ Z~~~~nv~~~UU~~~v~~ZU-o~Uv~N~v~~v~~-o v~Uv~~HU~3~ U U ~ s~ ~ • ~ s~ ~ N U ~ ~ N ~ O 4~ ~ ~ O U ~ ~ ~ ~ ~ 4-r ~ ~ O ~ ~ ~ ~ O O ~ ~ U U ~ ~ ~ ~ ~ ~ W ~ ~ ~4~ a O O O O ~ ~ ~ ~ ~ ~ ~ ~ ~ N ~ ~ O ~ ~ ~ ~ ~ ~ ~ ~ O c~ N ~ O N ~ ~ ~ c~ ~ ~ r/ N r~ ~ ~ ...a ..r ~ ..r U~ U ~ ~ ~ O~ ~ ~ ~ ~ ~ N ~ U U O~ O~ U • N 0°000 ~ ~~~o; ~ .Z m ~n Z N C/ir+ v~~ ~ ~ ~ ~ o0 ca? ~ ~ ~ ~ ~ N ~ N U U U ~ 0 ~ o a~ a~ ~ ~ ~ ~ ~ ~ ~ 0 0o ~ ~ ~ ~ ~ C ~ ~ ~ ~ z~zzM~ U +;~o ~ O~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ U ~ ~ a O ~ _ W ~ ~ ~ ~ N ~ bJ~ y.~ U O O ~ ~ ~ ry.y ~ ~ Z ~ U U ~ ~ ~ U ~ ~ O ~ U cd O q ~ ~ U ~ ~ Z U ~ U ~ ~ O ~ ~ ~ ~ ~ ~ ~ ~ U ~ ~ ~ U O ~ ~ ~ ~ 41 ~ ~ ~ s~ ~ ~ U O O ~ bJJ 0 N ~ -O U U cd O cd U ~ O ~ cd sr c~ ~ ~ ~ 0 I ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ U ~ c~ ~ O ~ ~ N ~ U ~ N OU Q ~ 0~~~ a~ a o ~ 0 Z Part 1, Summary-Summary of Alternatives Evaluated Alternative 1: Retail and Office Alternative 1 consists ofthe development of a mix of land uses in the Auburn Gateway project area to include retail and office space, new roads and utilities, parking, and stormwater detention facilities. Office buildings would generally be three stories or about 45 feet high, although one or more buildings could be up to 75 feet high. Approximately 200,000 square feet of retail space would be constructed. Retail buildings would generally be one story but could be up to 70 feet high. Retail uses as defined here include the retail sales of goods and services and some entertainment uses, as typically found in many shopping centers. Retail uses could occur in large pad" buildings such as large discount and membership-type stores (sometimes called big- boxretail), or in small- to medium-size buildings, including freestanding buildings such as restaurants with drive-in service. Impervious surfaces including roofs, roads, and parking areas would cover up to 90 percent of the project area. Parking could include surface parking areas and parking in structures. Alternative 2: Retail Alternative 2 is similar to Alternative 1, with the exception that the land use would be retail and service uses only. Alternative 2 would be more likely than Alternative 1 to include large retail stores, and would require less parking than Alternative 1. Alternative 3: Retail and Residential Alternative 3 is similar to Alternative 2, with the exception that the land uses would include multifamily residential as well as retail. The proposed Auburn Gateway Design Guidelines include standards for recreational open space that would be provided with the residential development. Preferred Alternative The Preferred Alternative would allow any of the range of uses described in Alternatives 1, 2, and 3 in a new mixed-use zone. I Street NE would be located on the east side of the Valley 6 Drive-in Theater and would connect to 45th Street NE, 49th Street NE, and South 277thStreet. A collector road, 49th Street NE, would extend through the Auburn Gateway project area due east from D Street NE to the eastern edge of the Auburn Gateway project area, then curve to connect to the proposed River Sands project located just east of the planning area. A major driveway serving the Auburn Gateway project area would be located on Auburn Way North between 45th Street NE and 49th Street NE.

Grading could include up to 650,000 cubic yards of fill material and 250,000 cubic yards of excavation. This increased amount of grading may be necessary in order to create a stormwater management system that operates adequately by gravity during extreme flood conditions. Except as described above, the features of the Preferred Alternative are the same as those of Alternative 1. The Preferred Alternative would be constructed over a period of approximately 16 years (through December 2020). No-Action/Existing Zoning Alternative The No-Action/Existing Zoning Alternative consists of development of the Auburn Gateway project area consistent with the current zoning. The current zones in the project area include 9.3 acres of heavy commercial (C3), 8.4 acres of multifamily residential (R4), and 41.5 acres of unclassified (UNC). The current zoning would accommodate approximately 130 single-family houses, l32 multifamily residential units, and 73,200 square feet of retail development. Under the No-Action/Existing Zoning Alternative, I Street NE would be built in the existing right-of way along the eastern edge of the planning area. No other changes in land use would be implemented under this alternative. tis~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Special Area Plan 10 Final EIS Part 1, Summary-Summary of Alternatives Evaluated Summar of Im actsYp Table 2 summarizes the impacts expected under the alternatives considered in this EIS.

I Street NE would be relocated westward to the Auburn Gateway project area, providing better access for commercial development and avoiding wetland impacts that would occur with the existing right-ofway alignment. A collector street (49th Street NE) would be extended across the planning area connecting the two existing segments of the 49th Street NE right-ofway in the planning area. While some wetlands would need to be filled to extend this road to the east of I Street NE, the alignment chosen for 49th Street NE is designed to have the least impacts on wetlands possible while providing safe and adequate access for the properties east of the Auburn Gateway project area. The existing I Street NE right-ofway could be partially vacated while still providing adequate access to all properties. Floodplain The Auburn Gateway proj ect would require the filling of approximately 27.5 acre-feet of the 100-year floodplain. The widening of South 277thStreet and the development of other parcels in the surrounding area would require additional filling in the floodplain. The City anticipates that the wetland mitigation project proposed by the Port of Seattle near the Green River, southeast of the Auburn Gateway project area, would provide compensation for floodplain filling for much or all of the planning area. The flood storage compensation is expected to be apportioned on the basis of existing flood storage volume, as described in the draft Northeast Auburn/RobertsonProperties Special Area Plan. The flood storage capacity created on the Port'swetland mitigation site could be used as floodplain compensation by the Auburn Gateway project or other developments south of South 277th Street. Currently available information suggests that the Port's wetlandmitigation project would compensate for filling of approximately 90 percent of all the existing flood storage capacity in this area.The Port has indicated that it intends to begin constructing the wetland in 2004 and that the would be available for use as floodplain compensation in approximately 3 years. If the Port's wetlandmitigation projector hydrologic connection is not completed before the development of adjacent property, the Auburn Gateway project or any other project in the planning area involving floodplain fill would be significantly affected, because floodplain fill compensation would then be the responsibility of the developer and would have to be located and constructed on the site or at a functional and suitable offsite location.tis~p-/ -' 01-0192-/-OOOfinalfeis.docNEAuburn/ Robertson PropertiesFinal EIS 17 Special Area Plan Part 1, Summary-Mayor Conclusions and Unresolved Issues Stormwater Management The estimated volume of fill material needed for the Auburn Gateway proj ect is based on the assumption that a detention system can be constructed to operate adequately during storm events and still provide drainage to the City stormwater conveyance system. The conveyance system experiences backwater conditions when the Green River, which is subject to flow control at the Howard Hanson Dam, is at its highest levels. The proponent's detention system concept for the Auburn Gateway project area relies on pumps and gravity flow. If the pump system does not meet City standards and is not acceptable, then it could be necessary to fill the project area even further to increase the elevation and provide gravity flow from the development's detention facilities to the City conveyance system. This final EIS acknowledges the possibility of the placement of as much as 650,000 cubic yards of fill material in the project area. A final decision on this issue will be made when the City has received further details on the design of the proposed stormwater management system. tis~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Special Area Plan 18 Final EIS Part 1, Summary-Irreversible or Irretrievable Commitment of Resources Irreversible or Irretrievable Commitment of Resources Uildlife habitat areas in the Auburn Gateway project area, other than areas within boundaries of wetlands that would remain and be enhanced, would be eliminated and replaced with urban development. Habitat areas that would be eliminated include most of an approximately 2-acre forested area that is currently the only such habitat in the planning area or vicinity. It is worth noting that the Port of Seattle plans to create a wetland southeast of the planning area that would provide new forested habitat over time. n~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Final EIS 19 Special Area Plan PART 2 Errata and Additional Analysis Part 2, Errata and Additional Analysis-Errata Errata The following are corrections to information provided in the draft EIS: Page 1, Introduction, first paragraph; and Page 31, History and Background of the Proposed Action, first paragraph: The text of the draft EIS indicates that the planning area is approximately 90 acres. One property was erroneously omitted from this tally. The EIS text should indicate that the planning area studied for the EIS includes approximately 120 acres. Page 23, Summary of Impacts, paragraph at top of page continued from previous page. Reference is incorrectly made to 49th Street SE. The statement should read: A connection to these properties could be made at either 49th Street NE or Robertson Way and would depend on the preferred access option. Following page 40, Figures 3, 4, 5, and 6 (depicting the alternatives considered in the draft EIS) show a wetland outside the Auburn Gateway project area to the northeast. A wetland delineation that was provided after these figures were created Parametrix 2003) showed this wetland to be smaller than the area shown on these drawings, but the drawings were not corrected. The wetlands shown in Figure 10 of the draft EIS are based on the Parametrix (2003) delineations, and the analysis was based on the configuration of wetlands shown in Figure 10. Page 94, Water Resources, end of first full paragraph. The drainage improvements on south and east side of the Auburn Gateway project area were incorrectly identified as VHV-1 from the Comprehensive Drainage Plan. The correct numbers for these improvements are VS and V6. n~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Final EIS 21 Special Area Plan Part 2, Errata and Additional Analysis-Preferred Alternative-Impacts and Mitigation Preferred Alternative-Im acts and Miti ationpg This section provides additional analysis of elements of the environment that would be affected by the Preferred Alternative differently than by the alternatives evaluated in the draft EIS: geology and soils, water, plants and animals, aesthetics, utilities and public services, and transportation. For air quality, noise, hazardous materials, historic and cultural resources, and land use, the impacts resulting from the Preferred Alternative are within the range of impacts that were determined to result from the alternatives evaluated in the draft EIS. Therefore, no further discussion of those elements of the environment is provided here. Geology, Soils, and Seismic Conditions Depending on the design of the stormwater management system in the Auburn Gateway project area, the volume of fill that would be necessary for development under the Preferred Alternative could be as much as 650,000 cubic yards, 30 percent more than the 500,000 cubic yards estimated in the draft EIS for the action alternatives. If the stormwater system cannot be designed in a manner to meet City standards using the proposed passive (gravity)/pump system, an entirely passive (gravity) system would be required. A passive system requires that stormwater be detained at an elevation that allows it to flow by gravity to the receiving system. Because the receiving system in the planning area becomes flooded from time to time, the entire project area would need to be filled up to an average of 6.5 feet, approximately 1.5 feet in elevation higher than the elevation discussed in the draft EIS. While placement of the additional fill is not preferred by RPG, the City does not yet have sufficient detail about the proposed stormwater system to approve the passive (gravity)/pump system; therefore, the additional fill must be considered. The additional fill would not result in any impacts on earth resources that are different from those that were discussed in the draft EIS, and similar mitigation measures could be employed to avoid significant impacts. Water Resources In terms of its effect on water resources, the primary difference between the Preferred Alternative and the alternatives evaluated in the draft EIS is that additional filling may be required in order to address the effects of flooding on stormwater management. Because a plan for a preliminary stormwater system has not been submitted, it is necessary to consider the possible need for sufficient filling to create a stormwater control system that could function by gravity alone. With either the passive (gravity)Ipump system proposed by RPG or the gravity system recognized by the City's Design and Construction Standards manual, the system would be n~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Final EIS 23 Special Area Plan Part 2, Errata and Additional Analysis-Preferred Alternative-Impacts and Mitigation required to control its runoff to the same degree. Therefore, the impacts on water resources would be the same with either system; the primary difference is in the dependability of a system involving pumps versus one with no pumps that functions by gravity alone. Special approval by the city engineer is required for all pump-operated facilities. The 650,000 cubic yards of fill necessary for the passive system is approximately 30 percent more fill than that required for the passive/pump system. The use of such a large amount of fill would raise the same concerns as those discussed in the draft EIS in terms of the possible effects on wetland hydrology. The mitigation measures proposed to address this concern and other impacts associated with the placement of a large quantity of fill would be sufficient to address the impacts due to the additional quantity of fill. Plants and Animals Two properties containing wetlands would be filled in order to accommodate the road alignment included in the Preferred Alternative (Figure 3). Several options were evaluated for extending 49th Street NE east of I Street NE. Because of the extent and location of the wetlands on the Stein property and the Port of Seattle construction access property, it would be impossible to extend this street without affecting wetlands. The preferred alignment was selected using several criteria: Provide access to I Street NE for properties east of the new I Street NE a ignment. Provide road design for aneast/west collector road with appropriate design speed, with intersections located far enough from South 277thStreet so that capacity on the principal arterials (South 277th Streetand I Street NE) is not compromised, and traffic movements are safe.Minimize overall wetland impacts, including fragmentation of larger wetlands.Minimize the need to acquire additional right-of way.Thepreferred roadway alignment would require filling of approximately 0.2 acresof wetlands within the Auburn Gateway project area. This fill would occur on the Stein property and the existing 49th Street NE right-of way (WetlandA, shown in Figure 3). Approximately 0.3 acresof wetlands ( Wetlands F and K, Figure 3) on the Port of Seattle construction access property would be filled in order to develop 49th Street NE and I Street NE in the preferred alignment.This total of 0.5 acresof wetland impact compares with 0.62 acresof wetlands on the Port of Seattle property that would be filled in order to develop I Street NE in its existing alignment.tis~p-/ -' 01-0192-/-OOOfinalfeis.docNEAuburn/ Robertson PropertiesSpecial Area Plan 24 Final EIS lr'hZO \~llhW~J ~~Z T kl O jg ® ~ PIYYY////~ Z LLO r Z ; yy~~J ~T d" . - 11~ N33 .rtl' i i iI ~ o ~Z ~ a ~ '1 ~ i J I~ I4 ~ ~ , ,I W W i I J W f~7 ~ v 0 1 # ~ I W 7 1 1 1 1 1 1 1 (~1 am 1 1 1 1 ~ a 1 1 11e ® Y ~ r Y ~ e 1 a 1 1 1 1 N ,rp~ tl ~y ~ a 1 1 1 1 a e e ~y ~ L.L I a' a m n~ O # 1 1 1Al ~ I..

Under the Preferred Alternative, a small portion of ~Uetland F would be isolated on the north side of 49th Street NE. Hydrologic connectivity between the isolated portions of Uetland F could be maintained by properly installing a culvert under 49th Street NE. South of the planning area, portions of several small wetlands may need to be filled in order to accommodate the preferred alignment of I Street NE. These impacts are expected to amount to less than 0.10 acres of wetland loss, compared to a loss of approximately 0.22 acres that would result from using the existing IStreet NEright-ofway in this area. Additional SEPA environmental review will be required for development of the extension of 49th Street NE east of the Auburn Gateway project area, and specific mitigation measures will be developed at that time. Mitigation for wetland impacts in the Auburn Gateway project area could be provided through enhancement of existing onsite wetlands or by creation of replacement wetlands. Aesthetics The Preferred Alternative includes new zoning and design guidelines that would apply to the project. Zoning and design review would allow further opportunity to review the impacts of a specific development. If 650,000 cubic yards of fill material is necessary for the Preferred Alternative, the Auburn Gateway project would be raised approximately 6.5 feet above existing grades, on average, which is approximately 1.5 feet higher than the grades described for the other alternatives in the draft EIS. This would make the bulk and scale of the buildings slightly more apparent. However, the Auburn Gateway Design Guidelines, together with the landscaping and other measures required by the Auburn City Code, include measures to mitigate the aesthetic impacts of the proj ect that would be effective in addressing this additional impact. As discussed in the draft EIS, the design review process envisioned in the special area plan provides an opportunity to evaluate the impacts of individual projects developed within the Auburn Gateway project area and to implement measures to address the specific impacts. Utilities and Public Services Any of the alternatives, including the Preferred Alternative and the No-ActionlExisting Zoning Alternative, would increase the demand for water. The 2001 Comprehensive Water Plan Auburn 2001b) identifies several improvements that would be needed to serve the area with adequate ire flow and system reliability (i.e., looped systems to ensure dependability and water quality). The needed improvements identified for development of the Auburn Gateway project area include the following: tis~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Special Area Plan 26 Final EIS Part 2, Errata and Additional Analysis-Preferred Alternative-Impacts and Mitigation 1.

DS-603-108,109-Constructa new 12-inchpipeline along South 277th Streetfrom Auburn Way North to the extension of I Street NE.At the project location, the fire department response time is likely to be around 8 to 10 minutes.This would be among the highest average response times in the city. In 2002, the City purchased a 1. 59-acresiteat 30th Street NE and I Street NE for a future fire station, which is expected to improve response times within the planning area.Transportation Impacts In the draft EIS, six potential access options with various alignments of I Street NE were evaluated for the Auburn Gateway project area (Figure 23 of the draft EIS). A preferred option has been selected (see Figure 3 of this final EIS). All signals shown on Figure 3 would be warranted by 2020 (see Appendix B). The preferred access option includes the following features:I Street NE would be located west of the existing City right-of wayonproperty owned by RPG. The location would be about 1,000 feeteast of D Street NE and 2,900 feetwest of the Green River Bridge. I Street NE should be designed as afive-lane minorarterial. A traffic signal would be located at the intersection of I Street NE and South 277th Street; itshould be operational when I Street NE opens to traffic.49th Street NE would be extended between Auburn Way North and I Street NE, and a signal would be installed at the intersection of Auburn Way North and 49th Street NE; it should be operational when 49th Street NE opens to traffic. A signal would also be installed at the intersection of I Street NE and 49th Street NE, when warranted. The entire section of 49th Street NE between Auburn Way North and I Street NE would be designed and built as a three-lane collector arterial. This collector road would be extended east to the east edge of the Auburn Gateway project area to eventually serve other properties located between I Street NE and the Green River. The extension of 49th Street NE would connect to and serve the proposed River Sands development (see Figure 3).D Street NE would be truncated so that it no longer intersects with Auburn Way North. Access to D Street NE from the south would be from 49th Street NE. D Street NE would be stop-sign controlled (asthe minor tis~p-/ -'01- 0192-/-OOOfinal feis.docNEAuburn/Robertson Properties FinalEIS 27 Special Area Plan Part 2, Errata and Additional Analysis-Preferred Alternative-Impacts and Mitigation leg) where it intersects 49th Street NE. Where D Street NE intersects South 277thStreet, turns to and from D Street NE would be restricted to right- in/right-outonly and would also be controlled by a stop sign.A major driveway leading to the Auburn Gateway project area would be constructed on Auburn Way North, between 49th Street NE and 45th Street NE. This intersection of the driveway with Auburn Way North could be signalized in the future, if and when it meets signal warrants.45th Street NE has already been improved to be a futureresidential collector arterial as designated in the City'sComprehensive Plan. No further roadway widening or improvements would be needed on 45th Street NE. However, when I Street NE is extended south to or beyond 45th Street NE, a traffic signal would likely be warranted and should be installed at the intersection of Auburn Way North and 45th Street NE. A signal would also be installed at the intersection of I Street NE and 45th Street NE if and when it is warranted in the future.The preferred circulation and access plan would provide regional benefits. First, the plan includes construction of a portion of I Street NE that ultimately would be part of a minor arterial extending from Harvey Road to South 277th Street. This arterial would parallel Auburn Way North and would help reduce congestion along Auburn Way North. Second, the extension of 49th Street NE between Auburn Way North and I Street NE would provide a continuous east-west arterial to B Street NE, which would improve cross-town movementand reduce congestion along the South 277th Street corridor. Finally, the proposed roadways would form a grid system that would improve overall mobility by creating parallel alternative routes. This grid also would improve emergency access- if one routeis blocked, emergency vehicles could find another route to or through the area.One issue to be determined is whether the major driveway access from Auburn Way North to the Auburn Gateway project area should be signalized. The benefit of signalization is that it would encourage more of the left-turning proj ect-related traffic toenter and exit the project area via the new driveway intersection, which would reduce traffic volumes and congestion at the intersection of Auburn Way North and 49th Street NE. Because the latter intersection is relatively close to the heavily congested intersection at South 277th Street and AuburnWay North, reductions in congestion and traffic queues at 49th Street NE would improve overall flow in the corridor. Also, multiple routes for accessing the project would serve to disperse traffic along the corridor, which also would reduce congestion. An analysis of traffic operations indicated that if a traffic signal is installed at the new driveway intersection on Auburn Way North, it would operate at LOS C or better at full build-out in the year2020. Appendix A of this final EIS provides diagrams illustrating the project-related traffic distribution usedfor this analysis. However, depending on the land use, traffic volumes may not be high enough to warrant a traffic signal at this intersection (e.g., if development issimilar to that in Alternative 3); therefore, the final decision to locate a signal at this intersection should be made when the site plans are submitted to the City. Periodic signal warrant analysis may be necessary to determine when and if signalization is needed.tis~p-/ -'01-0192-/- OOOfinalfeis.docNEAuburn/RobertsonProperties Special AreaPlan 28 Final EIS Part 2, Errata and Additional Analysis-Preferred Alternative-Impacts and Mitigation An analysis of traffic operations was performed to show how various intersections would operate under the three action alternatives analyzed in the draft EIS. The results shown in Table 3 indicate that all new roadway intersections within the project area would operate at LOS D or better if and when they are signalized. All intersections where signals are recommended would meet signal warrants for full build-out conditions (see Appendix B for discussion of the timing of warrant analyses). Even if land uses are substantially shifted within the project area so that one intersection accommodates more traffic than the level assumed in the EIS analysis, traffic operations are expected to continue to be acceptable. The only location where levels of service could fall below LOS D is the right-turn movement from northbound D Street NE to eastbound South 277thStreet. This movement would be controlled by a stop sign. If only two eastbound lanes are provided on South 277th Street, LOS D conditions would be exceeded for right-turn volumesin excess of about 290 vehicles per hour. If South 277th Street iswidened to include a third eastbound lane ( either as aright-turn drop laneor as a through lane), higher volumes could be accommodated on the right-turn movement fromD Street NE before the intersection level of service would degrade below LOS D conditions.Table 3.

The City of Auburn will perform a detailed review of the site plans, including driveway location, spacing, geometry,and traffic control for each project developed within the Auburn Gateway project area. To assist with this review and to ensure that subsequent site plan submittals include compatible driveway layouts, the City may require the submittal of a master site driveway plan in conjunction with the first building permit application. Additional traffic analysis, including levels of service and queuing analysis at driveways, may be required to confirm the geometric and traffic control needs associated with this master driveway plan and the specific development proposal. The City may also require a periodic review of traffic signal warrants to determine when signals should be installed at I Street NEl49th Street NE, I Street NEl45th Street NE, and Auburn Way North/45t1' Street NE.The results of the concurrencyanalysis discussed in the draft EIS indicate that the project's expected completion date of 2014 would notexceed the City of Auburn's transportation concurrency policy. However, under the PreferredAlternative, the timeframe for completion would extend through the year 2020, or approximately 16 years, as described elsewhere in this final EIS. If full build-out is extended beyond the year 2014, theSouth 277th Street corridor may not meet the concurrency thresholdof LOS D. It should be noted that the intersection of South 277th Street and West Valley Highway is included in thecorridor analysis even though it is not tis~p-/ -'01-0192-/-OOOfinal feis.doc NE Auburn/Robertson PropertiesSpecial AreaPlan30FinalEIS Part 2, Errata and Additional Analysis-Preferred Alternative-Impacts and Mitigation located in Auburn. This intersection affects overall corridor operations because of its proximity to the SR 167 interchange. Levels of service for the South 277thStreet corridor were calculated for conditions in the year 2020 ( Table 5). The cumulative reduction in delay that would be needed for the South 277th Streetcorridor to attain LOS D conditions is also presented. A cumulative delay reduction of about 41 seconds would be required for Alternative 1 to meet the LOS D threshold, whereas, a cumulative delay reduction of about 26 seconds would be required for Alternative 2.Alternative 3 would meet the LOS D threshold without any delay reduction measures.Table 5.

This plan should provide an efficient and safe pedestrian circulation system that includes appropriate crossing of I Street NE, D Street NE, and 49th Street NE at places where pedestrian/nonmotorized crossings are likelyto occur and where crossings can be safely accommodated with necessary improvements to minimize travel distance.With each development plan submitted for review, demonstrate that the proj ect is consistent with the approved master plan for pedestrian/nonmotorized circulation.tis~ p-/ -'01-0192-/- OOOfinalfeis.docNEAuburn/RobertsonProperties Special AreaPlan 32 Final EIS Part 2, Errata and Additional Analysis-Preferred Alternative-Impacts and Mitigation Prior to subdivision or development approvals, provide a master plan for site access for City review and approval. The plan should indicate driveway locations, lane geometry at the driveways, and traffic control. It should also evaluate signal warrants for the intersections of I Street NE/49th Street NE, I Street NE/45th Street NE, and Auburn Way North/45th Street NE. The plan should show how these driveways relate to internal circulation and nonproject driveways on the opposite side of the street. With each development plan submitted for review, demonstrate that the proj ect is consistent with the approved master plan for site access. At least every 2 years, perform signal warrant analysis for the intersections of I Street NE/49th Street NE, IStreet NE/45th Street NE, and Auburn Way Northl45th Street NE, so long as the intersections are unsignalized. (Signal warrants would be met by 2020 for all these intersections.) Install signals when warranted. Offsite Transportation Improvements Development of the Auburn Gateway project area could degrade traffic operations at several intersections in the study area. For the locations that would operate at LOS E or F in the year 2020 with or without development associated with the proposed project, mitigation could be provided by the project proponent contributing a proportional share to the intersection improvement. For locations that the project causes to degrade to LOS E or F, mitigation could be provided by the project proponent constructing the improvement or providing a proportional share in relation to the contribution to vehicle trips. As an alternative mitigation measure in those circumstances where LOS is exceeded, the City could elect to change its LOS standard. Table 6. Recommended mitigation measures for offsite intersections.

Discussions with City of Kent staff determined that no feasible mitigation exists for these intersections. Signal warrant thresholds are established by the 1~lanualon Uniform Traffic Control Devices MUTCD). Although signals are identified as required for this project, at least one of the MUTCD warrants must be met before a traffic signal is installed at an intersection, pursuant to City of Auburn policy.T~ anspo~tationConcur~encyAs previously mentioned, a reduction in cumulative delay of approximately 41 seconds or more is needed to meet LOS D under Alternative 1, the worst case; and a reduction of approximately 26 seconds of cumulative delay is required for Alternative 2, to meet the City of Auburn'stransportation concurrency policy threshold for the South 277th Streetcorridor.If development equivalent in traffic generation to Alternative 1 or 2 is not completed before the City of Auburn transportation concurrency policy threshold for the South 277th Street corridoris exceeded (estimated to be about the year 2014 for Alternative 1 and 2017 for Alternative 2),additional improvements in the South 277th Street corridor wouldbe necessary. The following improvement, consistent with the City's current plans forwidening South 277th Street, should be implementedfirst:Widen South 277th Street from Auburn Way toI Street NE to create three eastbound through lanes. With this change, the eastbound right-turn-only lane at the South277thStreetlAuburn Way intersection would be convertedto athrough-right lane. In addition, three eastbound throughlanes would be provided at the South 277th Street/I Street NE intersection.This improvementwould satisfythe concurrency requirement for Alternative 2 through 2020 and would provide additional time before another improvement would be needed to accommodate Alternative 1. If this improvement is completed but Alternative 1 is still not completed by the year 2019, one of the three measures listed below should be imp emente Widen southbound West Valley Highway to change the existing right-turn lane to a through-right lane.

The delay reduction associated with this improvement is about 29 seconds.or Reduce single-occupant-vehicle (SOV) trips for Alternative 1 by 20 percent. Transportation demand management strategies could include increased reverse-commutebus service, custom bus service, vanpool, van-share (where a commuter van is located at a maj or transit hub such as the Auburn or Kent commuter rail station), and carpool options.Other improvement options may also be available to achieve the desired level of service in the corridor. A smaller project, such as that described for Alternative 3, would also meet the concurrency requirements without any mitigation.To meet concurrency, the improvements would need to be in place before the completion of any phase of the Auburn Gateway proj ectthat would contribute to a cumulative total exceeding the concurrency standard. Table 7 lists the allowable cumulative PM peak-hour primary trips for the years 2014 through 2020. Any amount of development completed before 2014 with traffic generation less than or equal to that of Alternative 1 would comply with concurrency requirements for transportation.

While no comments on the draft EIS were received from King County, the county generally requests analysis of intersections affected by 10 or more peak-hour, peak- directiontrips. The intersection of SE 304tH Street and 13211dAvenue SE (west junction) would meet this threshold for all action alternatives. The intersection at SE 304th Street and 13211d Avenue SE (east junction) and the intersection at SE 304t1' Street and SR 18 westbound would meet this threshold for Alternatives 1 and 2 but not for Alternative 3. The intersection of SE 31211' Street and 11611' Avenue SE would meet this threshold only for Alternative 1. Since the draft EIS was published, a new level of service analysis has been performed for the intersections listed above for the various alternatives. Traffic volumes for these intersections were derived using information in Transportation Impact Analysis: City ofKent Impoundment Reservoir Site (Kent 2004). Traffic volumes forecasted for the year 2008 were used as the basis; these volumes included a 1 percent background growth rate plus traffic associated with 30 pipeline projects plus the traffic from the Impoundment Reservoir site. The worst-case condition for the Impoundment Reservoir site (Alternative 2) was used.

LOS and vehicle delay listed for westbound movements since eastbound movement is very minor.The level of service results show that the unsignalized intersections on Lea Hill would operate at unacceptable levels of service in the year 2020 without implementationof the Northeast AuburnlRobertson Properties Special Area Plan. (The transportation impact analysis for the City of Kent Impoundment Reservoir site predicted that the three unsignalized intersections would operate at LOS F in the year 2008.) The transportation impact analysis for the Cityof Kent Impoundment Reservoir site recommended mitigation measures for the intersection of SE 304th Street and 132~'~ Avenue SE, which would widen the eastbound approach to provide separate left- andright-turn lanes. That measure would dramatically improve operations for motorists turning right from eastbound SE 304th Street to southbound132~~d Avenue SE (LOS D at27.5 seconds of delay with the Auburn Gateway project). However, theleft-turn movement would continue to operate at an unacceptable level of service (LOS F) and delay would continue to be more than 300 seconds per vehicle. The LOS F condition would exist with or without the Auburn Gateway project. The transportation impact analysis for the City of Kent Impoundment Reservoir site also recommended mitigation for the intersection of SE 284th Street and 112thAvenue SE, which would add a southboundleft-turn lane on 112th Avenue SE and provide a separate westboundright-turn lane on SE 284th Street. That project would add a substantial volume of traffic to the turning movements served by this mitigation; however, these measures would not be needed to accommodate the Auburn Gateway project.The signalized intersection at SE 304th Street and132~~d Avenue SE (east junction) is projected to operate at LOS E in the year 2020 with or without the Auburn Gateway project.The traffic volumes generated by the proposed project would be small (Table 9.) The highest increase would occur for Alternative1(retail and office) at the intersection of SE 284th Street and 112th Avenue SE, where increases would range from 4 to1 o percent depending on the action alternative. The next highest increase would occur at the intersection of SE 304th Street and132~~d Avenue SE (west junction), at which Alternative 1 would increase volumes by less than 3 percent. Other intersections would experience increases of less than 2 percent for all alternatives.tis~p-/ -'01-0192-/-OOOfinalfeis. doc NEAuburn/Robertson Properties Special Area Plan 46 Final Part 3, Responses to Comments on the Draft EIS Table 9.

Even if this volume were to be half of these predictions, adual left-turn lane wouldstill likely be required because this volume is opposed by the peak-direction flows onSouth 277ti~ Street, which wouldbe eastbound toward Lea Hill.According to City of Auburn staff, the potential for a heavy westbound left-turn movement is reasonable. It reflects travel between the residential areas to the east and retail opportunities >n Auburn. It may also reflect some commuters who would use the Benson Highway for southbound travel in the afternoon. Finally, it is reasonable that motorists would turn left at I Street NE rather than continuing west to turn left at Auburn Way North, which would be a more congested location. It is for these reasons that the dual left-turn lane is recommendedfor conditions without or with the Auburn Gateway project.4-6-A roundabout onIStreet NE has been dropped from consideration.tis~p-/ -'01-0192-/- OOOfinalfeis.docNEAuburn/RobertsonProperties Final EIS47 Special Area Plan Part 3, Responses to Comments on the Draft EIS 4-7-Comment acknowledged.

Please refer to the description of thePreferred Alternative in the Summary section of thisfinal EIS.5- 3-Underthe preferred access option in this final EIS, 49t1i Street NE would be extended from Auburn Way North to the eastern edge of theAuburn Gateway project area, and from there a proposed alignment of this street would provide a single crossing over the Port of Seattle's34-acreconstruction access property and reach the eastern side of the Port property. It is anticipated that the development of thePort property and the Bristol property (the property east of thePort's34-acreproperty and adjacent to South 277111 Street, which contains the proposed River Sands project) would include construction of the east-west segmentacross the Port property. The extension of 49th Street NE would be designated as a collector arterial with three lanes (one lane in each direction plus a center left-turn lane). Implementation of the preferred access option would bring additional roadways and utilities closer to the Port's 34-acre propertyand thus may make the property more suitable for development. The area where 49th Street n~p-/ -' 01-0192-/-OOOfinalfeis.docNEAuburn/ Robertson PropertiesFinal EIS 49 Special Area Plan Part 3, Responses to Comments on the Draft EIS NE would cross the Port construction access property is located within the 100-year floodplain and would be filled. Within the Port property, the roadway would cross both wetland and upland areas. Approximately 0.3 acres of wetlands on the Port construction access property would be filled in order to develop 49t1i Street NE and I Street NE in the preferred alignment. This compares with approximately 0.62 acres of wetlands that would need to be filled to construct a roadway in the existing alignment ofI Street NE. Realignment of these streets would make possible vacation of 3.69 acres ofright-ofway and would require dedication of 1.92 acres of new right-ofway, yielding a net area of 1.77 acres lessright-of way than currently exists through the Port property. The exact amount of additionalright-of way needed for South277111 Street has not been determined but could be on the order of 0.5 acres. Most of the vacated right-ofway would be outside the floodplain, while most ofthe new right-ofway would be within the floodplain.

In addition,stormwater drainage and floodwater conveyance needs to be accommodated, either in a ditch or by other means. If stormwater is conveyed in a ditch and this area is to be dedicated public right-of way, additional dedication ofright-ofwaywould be required; if ina pipe, the pipe could be located below the trail. Detailed designs would be required when development of adjacent properties is proposed. The analysis for this special area plan does indicate that an additional lane would be required for left turns, and this lane would also be constructed on the south side of the street. While these features would require additional right-of way and eliminate potentially developablearea,without them the entire north end of the Port's construction access propertywould beinaccessible, would remain in the floodplain, and would therefore be undevelopable.5-5-Because the Port has notdevelopedor provided any specific site plans for its 34-acre construction access property, the assumptionused in the EIS is that the nonwetland portions of the Port's property would eventually be developedwith multifamily housing consistent with the City's zoning designation. The preferred accessoption provides for the future extension of a collector street east-west through the Port's 34-acre property linking tonorth-southarterial streets. The Preferred Alternative has been selected to minimize impacts on wetland resources on the Port's property while providing adequate accessfor such future development. See the response to comment 5-2.tis~p-/ -'01-0192-/-OOOfinalfeis. docNE Auburn/RobertsonPropertiesFinalEIS 51 SpecialArea Plan Part 3, Responses to Comments on the Draft EIS 5-6-The preferred access option anticipates the future extension of a collector street east-west through the Port's 34-acre construction access property linking tonorth-south arterial streets. The intersection of the new I Street NE and 49th Street NE would be signalized, and the east and west legs of this intersection would be designed to have exclusive left-turn lanes. With the worst-case development ofthe Auburn Gateway project area, this intersection is expected to operate at LOS A. The intersection could accommodate over 500 additional trips in the single proposed westbound lane before operations would decline to a LOS D. If higher levels of development were to occur on the Port's 34-acre construction access property, traffic operations could be improved with the addition of a second westbound lane. Excess capacity would also be available at the intersection of 49th Street NE and Auburn Way North. Thus, the new roadways constructed as part ofthe project would have adequate capacity to accommodate growth to the east. However, new development on the Port's property or other properties to the east could require additional improvements to principal intersections along Auburn Way North or South 277thStreet.5- 7-See the responses to comments 5-3 and 5-6. 5-8-Development plans for the Bristol property (the property containing the River Sands project east of the Port's 34-acre construction access property and adjacent to South 277 Street) were not available until after the publication ofthe draft EIS. The analysis in the draft EIS assumes that this property would be developed with multifamily housing at densities allowable under the existing zoning. Therefore, cumulative impacts were considered, even though specific site plans were not available. The Bristol property project will require additional SEPA analysis to ensure that the site plan developed for that project includes adequate provision for infrastructure and other mitigation measures. 5-9-See the responses to comments 5-3 through 5-6. Several options for access across the Port's 34-acre property were examined, as described in Part 2 ofthis final EIS. All the options examined would provide access to improved roads that lead to all nonwetland portions ofthe Port's property, and all options would require less right-ofway than that currently existing on that parcel. tis~p-/ '01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Special Area Plan 52 Final EIS Part 3, Responses to Comments on the Draft EIS 5-10-Future employers within the project area that meet ~ ~~etter 5) specified levels of employees and travel during peak hours would be subj ect to state 5-1a page 60, Table 4, Transportation, ProposedMatigatian Is the final bullet underthe requirements for commute trip control oftheproponent or City ofAuburn?

In addition, the FEMA maps could be modified with an amendment to the flood elevation that may also be made to reduce the area designated as flood-prone. The precise sequence of events necessary to achieve the FEMA floodplain map amendments are unknown at this time; therefore, the discussion of map amendments was left out ofthe affected environment discussion. 5-12-The general discussion provided here refers to the potential impacts of all proposed development on wetlands, including roadways. Most of the project area would consist of roads or parking facilities, with about 35 percent covered by buildings and 1o percent by landscape plantings, detention facilities, and natural areas. Additional discussion of wetland impacts due to road development associated with the Preferred Alternative is included in this final EIS. 5-13-Given the fact that several feet of fill would be placed over most of the project area, infiltration maybe possible in some areas, depending on the composition and compaction ofthe fill placed and the volume of water directed to those areas. Proposed locations for infiltration systems must meet the City standards for percolation.

Commenter #1-Mark Tullis H1.1 Will the proposed special area plan discussed in the draft EIS have the same impact on all properties in the planning area? Response: No. The EIS describes impacts of several actions. It is anticipated that the zoning would change only within the Auburn Gateway project area, and similarly the proposed planned action ordinance would apply only in Auburn Gateway project area. The design guidelines and other mitigation measures would apply specifically to the Auburn Gateway project area. The road improvements and floodwater management measures described in the EIS would apply to the entire planning area. H1.2 Will a master grading permit be issued? Response: It is anticipated that a master grading permit will be issued for the Auburn Gateway project area. This would not affect areas outside the Auburn Gateway project area, except as it would relate to road grades. H1.3 Will this project delay other proj ects in the area? Response: Inmost cases, no. See the response to comment 6-8 in the comment letters. H1.4 What month will the EIS be ready? Response: July 2004. H1.5 If no traffic light is provided at 49th Street NE and Auburn Way North there will be access problems for properties on 49th Street NE and on D Street NE. Response: See the response to comment 6-1 in the comment letters. Commenter #2 -Dennis DeLaHunt H2.1 Is it realistic to comment on combinations of access options? Response: Yes, it was anticipated that the access options could be combined in different ways to produce the Preferred Alternative described in this final EIS. H2.2 Will D Street NE be open to right-in/right-out on South 277thStreet?Response: See the response to comment 6-2in the comment letters.tis~ p-/ -'01-0192-/-OOOfinalfeis.docNE Auburn/RobertsonProperties Final EIS 59 Special Area Plan Part 3, Responses to Comments on the Draft EIS-Public Hearing Comments H2.3 will left turns be allowed to D Street from South 277thStreet? This is important and a left from 277th toD Street NE is also helpful.Response: Left turns would not be allowed to or from D Street NE. See response to comment 6- 2.H2.4 willthere be any change proposed to curb cuts near Auburn way NorthlSouth 277th Street? Theexisting curb cut on South 277th Street to theWilson Property is partially on the Tullis property. Access to South 277th Street and Auburn WayNorth are needed or else some other form of access.Response: See the response to comment 6-3 in the comment letters.H 2.5 Will development of South277th Street all be on thesouth side of the street? what elements will it include?Response: See the response to comment 6-4 in the comment letters.H2.6 when will the decisions bemade about the final configuration of street improvements to be required for South 277th Street? Response: See the response tocomment 6- 4 in the comment letters.Commenter #3 - VVes Giesbrecht H3.1 Excited to see things moving inthis area.Response: Comment acknowledged.H3.2 was stormwater conveyance through the areastudied?Response: Yes. See the Water Resources and Utilities and Public Services sections of the draft EI S and thi s final EIS .H3.3 All propertiesneed to move thewater from the east across the RPG property.Response: The project design would be required to comply with the City's Comprehensive Drainage Plan (Auburn 2002a), whichincludes a conveyance across the northern edge of the Auburn Gateway project area adj acent to South 277th Street. The Comprehensive Drainage Plan also identifiesimprovements needed to convey surface waters originating outside the boundaries of the project area to the south, to the north, and along the eastern and western boundaries of the project area.H3.4 will stormwater for the entire area beaccommodated?Response: All stormwater conveyances would be required to carry the volumes described in the City's Comprehensive Drainage Plan ( Auburn 2002a). The projectwould be required to design and install facilities to manage stormwater from impervious surfaces within the project area in accordance with City regulations governing tis~p-/ -'01-0192-/-OOOfinal feis.doc NE Auburn/Robertson PropertiesSpecialAreaPlan60 Final EIS Part 3, Responses to Comments on the Draft EIS-Public Hearing Comments stormwater treatment and detention. The Auburn Gateway project would not include facilities for stormwater management serving properties outside of the Auburn Gateway project area. H3.5 Will design guidelines apply outside the RPG area (called the Auburn Gateway project area in the draft EIS)`? Response: No, the design guidelines are expected to apply only to the properties within the Auburn Gateway project area. Zoning of properties in the city may be changed either through a request of a property owner or by aCity-initiated action. Therefore, properties outside the RPG properties can be rezoned either as part of this process or through any subsequent process initiated by property owners or the City. H3.6 ~Uill the existing C-3 zoning stay as it is outside of the RPG properties? Response: The existing C-3 zoning is not anticipated to change west of D Street NE or south of the Auburn Gateway project area. The Stein and McKee properties are within the Auburn Gateway project area and are not owned by RPG, but they would be rezoned H3.7 How will floodplain compensation be allocated`? How will the shortfall be accommodated? There should be an equitable distribution of benefit.Response: Compensation for floodplain filling would be provided by the Port of Seattle wetland mitigation site. As noted in the draft EIS, thePort's wetland mitigation project may not provide sufficient compensation for all floodplain to be filled in the area south of South277th Street. Compensation provided by the Port of Seattle wetland mitigation project would be allocated to floodplain filling projects in the planning area in the following manner: 1. First, full compensation would be allocated for all planned street projects and any other filling necessary for planned public infrastructure, such as stormwater detention facilities associated with area streets. 2. Then the remaining floodplain area to be filled would be estimated on the basis of the best available topographic information at that time. 3. This estimate, (i.e., the remaining requirement for compensatory flood storage capacity) would be compared with the remaining compensatory flood storage capacity available from the Port's project, to establish a ratio for allocation of the compensatory credit to all projects on private property south of South 277thStreet.For example, if 33 acre-feetof compensatory credit is needed for all filled floodplain areas on private property, and 30 acre-feetof compensatory credit remains available from the Port'sproject, the ratio would be 90 percent.4. As each application for private development is made, the applicant could receive compensatory credit from the Port project at the established ratio. Compensation n~ p-/ -'01-0192-/-OOOfinalfeis.docNE Auburn/RobertsonProperties Final EIS 61 Special Area Plan Part 3, Responses to Comments on the Draft EIS-Public Hearing Comments for any additional floodplain filled would remain the responsibility of the individual development. H3.8 Is there any consideration of wetland banking? Have any policies been finalized? For example could smaller wetlands be filled and mitigated for offsite or through a wetland bank? Response: Offsite mitigation for wetland impacts could beprovided on aproj ect-by- projectbasis, provided the proposed mitigation meets all other regulatory requirements. No mitigation bank is proposed in the Auburn Gateway project area, and no offsite mitigation approaches have been evaluated in the EIS. Commenter #4 -Ronald Stein H4.1 The I Street roundabout is a safety hazard. Response: A roundabout on I Street NE has been eliminated from consideration. As noted in the draft EIS, the roundabout is not expected to be capable of functioning adequately with full development of any of the alternatives. H4.2 Mr. Stein prefers Access Option A (for alignment of I Street NE); C is okay; B is not acceptable. Response: Comment acknowledged. See Figure 3 of this final EIS for the access layout for the Preferred Alternative. H4.3 All land use alternatives are ok Response: Comment acknowledged. H4.4 Should pursue offsite wetland mitigation approach. Response: See the response to comment H3.8. H4.5 Should look at wetland mitigation banking and filling of smaller wetlands. Response: See the response to comment H3.8. H4.6 Can Mr. Stein pursue wetland banking independent of the EIS? How will it affect this project? Response: Yes. Pursuing a separate development proposal would not affect the Auburn Gateway proj ect or the adoption of the special area plan. However, any application would be required to be consistent with the special area plan once it is adopted. tis~p-/ -'01-0192-/-OOOfinalfeis.doc NE Auburn/Robertson Properties Special Area Plan 62 Final EIS Part 3, Responses to Comments on the Draft EIS-Public Hearing Comments H4.7 ~Uill wetland mitigation need to be in the city or could it be anywhere in the Mill Creek assn?Response: The City of Auburn would consider potential offsite mitigation located outside the city limits as long as it is within the Mill Creek basin.H4.8 Placing the Auburn Gateway stormwater pond on his property is a problem because that puts him pretty much out of business since it consumes the majority of his undeveloped property. (Mr. Stein has been coordinating with the project proponent and also indicated that he would speak to the RPG representatives in attendance about this concern.)Response: Comment acknowledged. The stormwater facility locations shown in the draft EIS are conceptual. Under the Preferred Alternative, RPG anticipates that the stormwater facilities for the Auburn Gateway project area would be provided south of the Stein property and elsewhere in the project area.n~p-/ -'01-0192-/-OOOfinalfeis. doc NEAuburn/Robertson Properties Final EIS 63 Special Area PART 4 References and Distribution List Part 4, References References Following are the references cited in thefinal EIS Additional references can be found in the draft EIS Architects BCRA. 2003.

Heffron, P.E., P.T.O. Subject: Northeast Auburn Special Area Plan Signal WarrantAnalysis The Northeast Auburn Special Area Plan's transportation analysis recommended traffic signals be installed at up to five intersections. To test the need for these signals, traffic signal warrant analysis was performed for all six locations assuming full build conditions in the year 2020. The intersections include: S 277thStreet/IStreet NE Auburn Way North/49thStreet NE Auburn Way North/45thStreet NE • I Street NE/49thStreet NE I Street NE/45thStreet NE Traffic Signal Warrant Definitions The Manual on Un~forn~ Traffic Control Devices (MUTCD) -Part 4 of the Millennium Edition, (US Department ofTransportation -Federal Highway Administration, 2001) is the standard used to determine whether or not a traffic signal should be installed at a given location. The MUTCD states, "A traffic control signal should not be installed unless one or more of the factors described in this section are met." The eight (8)warrants for traffic signal installation are listed below:Warrant 1-Eight-HourVehicular Volume (minimum volumes over eight hours)Warrant 2 -Four-HourVehicular Volume (minimum volumes over four hours)Warrant 3 -Peak Hour (minimum volume over one hour period)Warrant 4 -Pedestrian Volume • Warrant 5 -School Crossing (adequacy of gapsnear school crossing location)Warrant 6 -Coordinated Signal System (platooning for one-wayor two-waystreets)Warrant 7 -Crash Experience (number and type ofaccidents) Warrant 8 -Roadway Network (for organized traffic flow networks) The intersections where traffic signals are recommended for the Northeast Auburn Special Area Plan do not currently exist. Thus, eight-hour traffic volumes, pedestrian volumes, and accident history do not yet exist to measure these warrants. The only data available are future peak hour traffic volumes. Thus only Warrant 3 can be tested. MUTCD warns that this warrant should only be applied in unusual cases when a development discharges a high volume of traffic in a very short time. However, it does provide a good indicator ofwhether or not the other volume warrants may be met. 6544 NE 61st Street, Seattle, WA 98115 Phone: (206) 523-3939 Fax: (206 523-4949 Northeast Auburn Special Area Plan Si nal Warrant Anal sis ~ g Y July 28, 2004 Page 2 of 3 The volume thresholds for the Peak Hour Volume Warrant are shown in Figure 1.

As a point ofreference, the minimum traffic volumes for both the eight-hour and the four-hour volume warrants were reviewed. Three ofthe five signals are proposed to be located along Principal Arterials in the City of Auburn: South 277thStreet and Auburn Way North. Existing traffic volumes on these streets already exceed the minimum traffic volume required for the major street portion or both of thesewarrants. It is likely that the eight-hourvolume for these major streets (required to be 600 vehicles total in both directions) is exceeded for more than eight hours each day. Thus, the traffic volume on the intersecting side streets would only need to be 150 vehicles for each of those same eight hours. Given the probability of through traffic using the three minor streets ( I Street NE, 49th Street NE and 45th Street NE) and given the size of theproposed development, it is also likely that all would meet the eight hour warrants. Northeast Auburn Special Area Plan Si nal Warrant Anal sis ~ g Y July 28, 2004 Page 3 of 3 Recommendations Install traffic signal at the South 277thStreet/IStreet NE intersection when I Street NE opens to traffic. This signal should go in immediately upon completion of the new roadway due to its location at the junction of two arterials. Traffic speeds and volumes at this location will justify a traffic signal upon opening.Install traffic signal at the Auburn Way NE/NE49th Street intersection when 49th Street NE is constructed east of AuburnWay. This signal should be operational immediately upon completion of the new roadway due to its location on Auburn Way and the fact that NE 49th Street is desired to be the primary connection between I Street NE and Auburn Way N until such time as the full I Street NE corridor is complete. A traffic signal at this location will attract the through traffic to this route as desired. This traffic signal will also serve as a primary access point for the new development proposed on the RPG site. It should be noted that the need for the traffic signal would not exist if not for the need to build a new east- westconnection street to serve the RPG property.Monitor traffic volumes at the Auburn Way NE/NE45th Street, I Street NEl49th Street NE, and I Street NEl45th Street NE intersections and install traffic signals when traffic signal warrants are met. All intersections would meet traffic signal warrants in the year 2020 with the project. Prior to full build out of theproject, it is recommended that signal warrants be reviewed as part of the Master Plan for Site Access that will be prepared prior to building permits being submitted for the project. Periodic review (at least every two years) of the signal warrants should then be performed until all signals are installed.MCH/ mch
