For the disposal of sewage hereafter collected by the City and delivered to Metro the City shall pay to Metro, on or before the last day. of each month during the tern of this Agreement, commencing on the first day of the month next following the date of execution of this contract or the acceptance by Metro of a federal grant by the United States Environmental Protection Agency for the construction of the "Auburn Interceptor, " as hereinafter defined, whichever is the later, a sewage disposal charge determined as provided in this Section 5. 1. For the quarterly periods ending March 31, June 30, September 30 and December 31 of each year, every Participant shall submit a written report to Metro setting forth (a) the number of Residential Customers billed by such Participant for local sewerage. charges as of the last day of the quarter, (b) the total number of all customers billed by such Participant as of such day and (c) the total water consumption during such quarter for all customers billed by such Participant other than Residential Customers. The quarterly water consumption report of the City shall be taken from water meter records and may be adjusted to exclude water which, under the rules and regulations of Metro, needs not and in fact does not enter the sanitary facilities of a customer. Where actual sewage flow from an individual customer is metered, the metered sewage flow shall be reported in lieu of adjusted water consumption. The total quarterly water consumption report in cubic feet shall be divided by 2,700 to determine the number of Residential Customer equivalents represented by eacH Participant' s customers other than single family residences. Metro shall maintain a permanent record of the quarterly customer reports from each Participant. The Citvts first quarterly report shall cover the period from the date when sewage is first delivered to Metro to the end of the quarter in which such delivery occurs and shall be submitted within thirty rlas thereafter. Succee:!ix7q reports _5_ shall be made for each quarterly period thereafter and shall be submitted within thirty (30) days following the end of the quarter. . • 2. a) To form a basis fer detcrmini.ng the monthly sewage disposal charge to be paid by each Participant during any particular quarterly period, Metro shall ascertain the number . of Residential Customers and Residential Customer equivalents of each Participant. This determination shall he made by t�.:.ing the sum of the actual number of Residential Customers reported as of the last day of the next to the. last preceding quarter and the -average number of Residential Customer equivalents per quarter reported for the four quarters encing with said next to the last preceding quarter, adjusted for each Participant to eliminate any Residential Customers or Residential Customer equivalents whose sewage is delivered to a governmental agency other. than Metro or other than a Participant for disposal outside of the Metropolitan Area. The number thus determined is hereinafter called the "basic reported number". b) For the initial eeriod until the City shall have submitted six consecutive quarterly reports, the basic reported. number of Residential Customers and Residential Customer ecui- = valents of the City shall he determined. as provided in this subparagraph (b) . On or before the tenth day of each month beginning with the month prior to the month in which sewage from the City is first delivered to Metro, the City shall sub- mit a written statement of the number. of Residential Customers and Residential Customer equivalents estimated to be pilled by the City during the next succeeding month. For the purpose of _6- • determining the basic reported number of Residential Customers or Residential Customer equivalents of the City for such next succeeding month, Metr❑ may at its discretion adopt either such estimate or the actual number of Residential Customers and Residential Customer equivalents reported by the City as of the last day of the next to the last preceding reported quarter. ' I After the City shall have furnished six consecutive quarterly reports, the basic reported number of Residential Customers and Residential. Customer equivalents of the City shall be determined - as provided in the immediately preceding subparagraph (a) . c) If the City shall fail to submit the required • monthly and/or quarterly reports when due, Metro may make its Own estimate of the ntmber of Residential Customers and Resi- dential Customer equivalents of the City and such estimate shall constitute the basic reported number for the purpose of deter- mining sewage disposal charges. d) The basic reported number of Residential Customers and Residential Customer equivalents of -the City shall be further adjusted by adding theret❑ twenty-five percent (25%) of the number of Residential Customers or Residential Customer equiva- lents ❑f the City located outside the boundaries of Metro. The sum thus determined is hereinafter called the "adjusted reported - number". If all of the area located within the City or any area located outside the City and served into its Local Sewerage Facilities shall be annexed to Metro at any time after the date of this agreement or if the twenty-five percent additive adjustment shall have been paid by the City for a period of ten years, said additive adjustment shall be eliminated effective as ❑f the first day of the month following such ann,eeatictin as to the number of -7- Residential Customers or Residential Cu stor'ler equivalents located within such annexed area and in any event shall he eliminated entirely upon the tenth anniversary of, the date when sewage disposal charges shall have first been paid to Metr❑ 'by the City. If the additive adjustment described above shall not be applied to the Residential Customers or. Residential Customer equivalents of any other Participant located outside of the present boundaries of Metr❑ under any future agreement. between Metro and such Partici- pant or shall be applied in a lesser amount, then the additive adjustment described in this paragraph (d_) shall be correspondingly . reduced or deleted. The adjusted reported.' number of Residential Customers and Residential Customer equivalents of the City shall - he the number ❑f Residential Customers and Residential. Customer equivalents reported 1.1, the City for the purpose of determining sewage disposal charges pursuant to Paragraph 3 of this section. 3. The monthly sewage disposal charge payable to Metro shall be determined as follows: - a) Prior to July 1st of each year, .Metro shall determine its total monetary requirements for the disposal of sewage during the next succeeding calendar year. Such requirements shall include the cost of administration, operation, maintenance, re- pair and replacement of the Metropolitan Seweraae System, es- tablishment and maintenance of necessary working capital and reserves, the requirements of any resolution providing for the issu_,nee of revenue bonds of Metro to finence the acquisition, construction or use of sewerage facilities, plus not to exceed 1% of the foregoing requirements for general administrative overhead costs. b) To determine the monthly rate per Residential Customer ❑r Residential Cu to;i+e7: equivel. 'nt to be used dur.iee -•L1 M the next succeeding calendar year, the total monetary requirement, for disposal of sewage as determined in subparagraph 3(a) of this section shall be divided by twelve and the resulting quotient shall be divided by the total number of Residential Customers and Residential Customer equivalents of all Participants for the October--Deccmber quarter pre- ceding said July 1st. c) The monthly sewage disposal charges paid by each Parti- cipant to Metro shall be obtained by multiplying the monthly rate by the number of Residential Customers and Residential Customer equiva- lents of the Participant. An additional charge may be made for sewage or wastes of unusual quality or composition requiring special treat- ment, or Metro may require pretreatment of such sewage or wastes. An additional charge may be made for quantities of storm or ground waters entering those Local Sewerage Facilities which are constructed after 1anuary 1, 1961, in excess of the minimum standard established by the general rules and regulations of Metro, except that any such additional charges shall be offset by any expenditures. made by the City on the ' planning and development of facilities for the correction of inflow and infiltration into the existing sewerage system of the City. If the City shall expend more than $50,000.00 in any one year on such planning and development from any source other than categorical grants, the amount expended over S50,000.00 in that year may be credited once to any future years in which the actual expenditure was less than $50,000. 00 so as to avoid the collection in those years of the addi- tional charge provided in the immediately preceding sentence. 4. A statement of the amount of the monthly sewage disposal charge shall be submitted by Metro to each Participant on or before the first day of each month and payment of such charge shall be due on the last day of such month. If any charge or portion thereof due to Metro shall remain unpaid for fifteen days following its due date, the Participant shall be charged with and pay to Metro interest en the amount unpaid from its due date until paid at the rate of 61 per annum, And Metro may, upon thy' fai.lurc! of any Participant to pay ::ueh amount, enforce payment by any remedy available at law or equity. -9- 5. The City irrevocably obligates and binds itself to pay As sewage disposal charge out of the gross revenues from sewage collected or received by the City. City further binds itself to establish, main- tain and collect charges for sewer service which will at all times be sufficient to pay all costs of maintenance and .operation of the sewer system of the City, including the sewage disposal charge payable to Metro hereunder and sufficient to pay the principal of and interest on any revenue bonds of the City which shall constitute a charge upon such gross revenues. It is recognized by Metro and the City that the sewage disposal charge paid by the City to Metro shall constitute an expense of maintenance and operation of the sewer system of the City. The City shall provide in the issuance of future sewer revenue bonds of the City that expenses of maintenance and operation of the sewer system of the City shall be paid before payment of principal and interest of such bonds. The City shall have the right to fix its own schedule of rates and charges far sewer service provided that same shall produce revenue sufficient to meet the covenants contained in this Agreement. Section 6. Responsibility of City. The City shall be respon- sible for the delivery to the Metropolitan Sewerage System of sewage collected by the City, for the construction, maintenance, and operation of Local Sewerage Facilities, for the prompt connection of all premises _ served by such facilities, and for the payment of all costs incident to the collection of such sewage and its delivery to the Metropolitan u Sewerage System. Section 7, Racords. Permanent books and records shall be kept by Metro and the City of the respective rates established, the volumes of sewage delivered and discharged into the Metropolitan Sewerage System wherever such volumes are measured and the number of Residential Custom- ers and Residential Customer equivalents reported. In addition, Metro shall keep complete books of account showing all costs incurred in connection with the Metropolitan Semen.a,c System, and the City shall -10- keep complete records showing the amount billed to each of its customers for sewer service and the basis used for such billing including sewage flow and water consumption for each customer where applicable, The records required by this paragraph shall be avail- able for examination by either party at any reasonable time. Section B. Development of Metropolitan Sewerage System It is contemplated that the Metropolitan Sewerage System will be developed in stages and, except as provided in Section 9 hereof, the nature of all facilities of the Metropolitan Sewerage System to be constructed, acquired or used and the time of such construction, acquisition or use shall be determined in the sole discretion of Metro, it being coriemplated that Metro shall ultimately provide sewage. disposal for the entire Metropolitan Area and such adjacent areas as may feasibly be served into the Metropolitan Sewerage System. Section 9. Construction of Certain Metropolitan Trunk Sewers by Metro. Metro agrees that it will design, construct and inspect facilities of the Metropolitan Sewerage System generally described on Exhibit "A" attached hereto (the "Auburn interceptor") upon the execution of this contract and the acceptance by Metro of a fed- eral grant by the United States Environmental Protection Agency for construction of said Auburn Interceptor. The facilities shall be connected and ready for service within twenty-four calendar months next after the execution of this contract and the acceptance by Metro of a federal grant by the United States Environmental protection Agency for the construction of the Auburn Interceptor. The date of connection may be extended by the time consumed by acts of God, strikes, material shortages or other delays beyond the control of Metro or its contractors. In the event of a dispute -11- over the existence of any of the delays permitting such date to be extended or over the amount of time ❑f such extension,' either party may submit such dispute to the Superior Court of Xing County for arbitration. If such facilities are not completed by such date or extension thereof, the amount of Metro charges paid by the City from such date to the actual date of completion thereof may be used by the City as a credit in determining the feasibility of construction of future Metropolitan Sewerage System facilities which the City may re- quest Metro to build. Such credit shall be applied directly against that portion of the cost of such future facilities which is borne by Metro, other than by grants, and the test of feasibility used by Metro shall be one which is then generally applied by Metro t❑ all extensions of the Metropolitan Sewerage System. In addition, Metro shall place in every construction con- tract relating t❑ the Interceptor sewers described in Exhibit "A" a provision for the payment of each such contractor ❑f liquidated . damages to the City of $300.00 per day for each day such construc- tion has not been completed after such date or extension thereof, and such liquidated damage provision shall provide for the enforce- ment thereof by the City. Metro shall not approve any such time extension without prior approval ❑f the City, which shall not be unreasonably withheld. Metro shall construct that portion of the West Valley Interceptor from l l t h Avenue North (in Algona) to Main Street (in Auburn) within a reasonable time after the Auburn Interceptor shall have been completed and the City shall have requested such construction, and the City shall provide a pump station and force main connection fro, the West Valley Highway along Main Street to -12- the existing Boeinc, Trunk sewer. Metro shall approve the design of and shall operate and maintain the pump station. At such time as the pump station is no longer required by Metro, thZt possession of such facility and responsibility for operation and maintenance therefor shall revert to the City. At such time as the City shall request Metro to construct • additional Metropolitan Sewerage System facilities within King County and within the drainage area of the City's Local Sewerage Facilities and such construction is feasible under the test of feasibility then generally applied by Metro to all extensions of the Metropolitan Sewerage System, Metro shall construct such additional facilities within a reasonable time after such request. The City shall grant to Metro without cost a fifteen-fact permanent easement and an adequate construction easement on City property for the construction of a portion of the Auburn T_nterceptior. The location of such easement shall commence. at the influent struc- ture of the existing City Sewage Lagoon, thence northerly and gen- erally parallel to the existing City Sewage Lagoon to 30th Street Northeast, the exact location to be agreed upon by Metro and the City. Section 10. Use by Metro of City Sewerage Facilities. Certain existing sewerage facilities of the City can serve as "temporary" Metropolitan Sewerage System facilities and certain existing sewerage facilities can 'serve as "permanent" Metropolitan Sewerage System facilities.

Xf sewage disposal charges are chargeable to the City and if the City shall construct an additional freeway crossing with the approval by Metro of the design and location of such - facility or crossing, the City shall he reimbursed for the City's actual cost thereof (less any grants received). in addition t❑ the amount of reimbursement set forth below, The freeway reim- bursement shall be made in cash within thirty-five (35) days fol- lowing completion and billing by the City, but no sooner than the takeover, date. The City shall continue to own the facilities described in this Section 10 and shall continue to pay the principal ❑f and interest on any bonds issued to pay in whole or in part the cost of acquisition and construction of such facilities. provided that facilities which are designated as "pertranent" shall be conveyed by the City to Metro by quit claim deed upon payment of all presently outstanding revenue bonds or general -obligation bonds of the City secured by or issued to acquire or construct said facilities. The right of Metro to use any of the facilities which arc designated as "temporary" shall expire at such time as Metro shall no longer require the use of such portion. Upon thirty (30) days' notice by Metro to the City, such temporary facilities shall be returned to the City and Metro's obligation to maintain, - operate, repair and replace these temporary facilities shall cease. It is contemplated by this Agreement that the City shall, at the earliest practicable date ,and at its expense, separate the storm and sanitary sewage in areas of the City where storm and sanitary sewage are now combined. The right of Metro to use the -3 4 - City Sewage Treatment Lagoon afte- interception shall terminate when the City shall have applied after the date of this Contract at least $207,000 of City funds, from any source other than categorical grants, to the contr.uction of :storm sewer separation facilities. Metro shall have the right to salvage any equipment which it has installed or purchased from the City in the "temporary" facilities after the period of Metro's use, otherwise such facilities shall be returned to the City in "as then is" condition upon expiration of use by Metro.

The Metro reim- uursement shall include the actual cost of acquisition of the property plus the current depreciated value of the lift station facility which is agreed to be $37,445.00._ Metro further agrees that prior to advertisement for bids for the construction of the facilL ties genei:ally described on Exhibit 'A" attached hereto, or any future construction of Metropolitan Sewer- age System facilities to which Local Sewerage Facilities of the City could directly connect, it will submit plans and specifications for those facilities to the City for its review and upon timely notice to the City may indicate to Metro where manhole stub connections should be installed and Metro shall thereafter install same, in anticipation of further future connections by the City at those points. The install- ation of such stubs will be at no cost or expense to the City. The City shall have the right to connect any Local Sewerage Facilities to those stubs. The City shall also have a right to approve the location of Metropolitan Soweroge lysteM vu City-owned property or ri'Pub of w:iv;, wi.ioh approval shall not be unrea om''h1y withhold. -15- The CiLy shall give written notice to Metro prior, to the takeover date, setting fcrth the manner in which the amount of reim- bursement shall be paid. The City may elect to receive all or any portion of said amount in cash within thirty (30) days following the date when sewage disposal charges shrill first be chargeable hereunder (hereinafter called ''cash payment date") and may elect to receive any portion which is not paid on said cash payment date together with interest thereon at the rate of 4% per annum from said date, in the • form of a credit against the City's monthly sewage disposal charge in equal monthly amounts sufficient to amortize such unpaid amount of reimbursement and interest thereon prior to July 1, 1980. The City may at any time after the cash payment date elect to receive any un- paid portion of the amount of reimbursement in cash with interest at the rate of 4% per annum to date of final payment by giving written notice to Metro at least one year prior to the date such final payment is to be made. Section 11. joint Use of Auburn Interceptor. The City and Metro agree that the Auburn Interceptor. (hereinafter called "the interceptor') shall serve as both a Metropolitan and a Local Sewerage Facility wherever the City has authority to provide local service. The City shall have the right to make direct local connections to said Interceptor'for which the City shall pay to Metro, before making said connection, the sum of $8.00 per front .foot of each parcel of property served on each side of the Interceptor or a total of $16. 00 per front foot of each parcel of ' c property served if local service is given on both sides of the Interceptor. Said amount represents the estimeted cast of constructing an eight-inch (8") local sewer on the same alignment as the Interceptor throughout that portion where local connections are allowed. Upon payment of said amount, the City shall own an eight-inch (9") equvalent share of the Interceptor where loco] service is given on both sides of the Interceptor, and one-half_ thereof where service is given on onl.l+ one side.

Aj endment of Sertion 5 of the Basic Agreement. Section 5 of the Basic Agreement is hereby amended to read as follows: "Section 5. Payment for Sewaoe Disposal. For the disposal of sewage hereafter collected by the City and delivered to Metro the City shall pay to Metro on or before the last day of each month during the term of this Agreement, a sewage disposal charge determined as provided in this Section 5. 1. For the quarterly periods ending March 31, June 30, September 30 and December 31 of each year every Participant shall submit a written report to Metro setting forth: (a) the number of Residential Customers billed by such Participant for local sewerage charges as of the last day of the quarter, (b) the total number of all customers billed for local sewerage charges by such Participant as of such day, and (c) the total water consumption during such quarter for all customers billed for local sewerage charges by such Participant other than Residential Customers. The quarterly water consumption report shall be ti taken from water meter records and may be adjusted to exclude water which does not enter the sanitary facilities of the customer. Where actual sewage flow from an individual customer is metered, the metered sewage flows shall be reported in lieu of adjusted water consumption. The total quarterly water consumption report in cubic feet shall be divided by 2,250 to determine the number of Residential Customer equivalents represented by each Participant's customers other than single family residences. Metro shall maintain a permanent record of the quarterly customer reports from each Participant. 2 The City'a first quarterly report shall cover the first quarterly period following the date when sewage is first delivered to Metro and shall be submitted within thirty days following the end of the quarter. Succeeding reports shall be made for each quarterly period thereafter and shall be submitted within thirty (30) days following the end of the quarter. 2. (a) To form a basis far determining the monthly sewage disposal charge to be paid by each Participant during any particular quarterly period, Metro shall ascertain the number of Residential Customers and Residential Customer equivalents of each Participant. This determination shall be made by taking the sum of the actual number of Residential customers reported as of the last day of the next to the last preceding quarter and the average number of Residential Customer Equivalents per quarter reported for the four quarters ending with said next to the last preceding quarter, adjusted for each Participant to eliminate any Residential Customers or Residential Customer equivalents whose sewage is delivered to a governmental agency other than Metro or other than a Participant for disposal outside of the Metropolitan Area. (b) For the initial period until the City shall have submitted six consecutive quarterly reports, the reported number of Residential Customers and Residential Customer equivalents of the City shall be determined as provided in this subparagraph (b) . On or before the tenth day of each month beginning with the month prior to the month in which sewage from thv City is First delivered to Metro, the City shall submit a written statement of the number of Residential Customers and Residential Customer equivalents estimated to be billed by the City during the next succeeding month. For the purpose of determining the basic reported number of Residential Customers and 3 Pe? 2 /) Residential Customer equivalents of the City for such next succeeding month, Metro may at its discretion adopt either such estimate or the actual number of Residential Customers and Residential Customer equivalents reported by the City as of the last day of the next to the last preceding reported quarter. After the City shall have furnished six consecutive quarterly reports the reported number of Residential Customers and Residential Customer equivalents of the City shall be determined as provided in the immediately preceding subparagraph (a) . (c) If the City shall fail to submit the required monthly and/or quarterly reports when due, Metro may make its own estimate of the number of Residential Customers and Residential Customer equivalents of the City and such estimate shall constitute the reported number for the purpose of determining sewage disposal charges. 3. The monthly sewage disposal charge payable to Metro shall be determined as follows: (a) Prior to July 1st of each year Metro shall determine its total monetary requirements for the disposal of sewage during the next succeeding calendar year. Such requirements shall include the cost of administration, operation, maintenance, repair and replacement of the Metropolitan Sewerage System, establishment and maintenance of necessary working capital and reserves, the requirements of any resolution providing for the issuance of revenue bonds of Metro to finance the acquisition, construction or use of sewerage facilities, plus not to exceed 1% of the foregoing requirements for general ads4n strti7e cart.... costs. (b) To determine the monthly rate per Residential Customer or Residential Customer equivalent to be used during said next succeeding calendar year, the total monetary requirements for disposal of sewage as determined 4 Pet' &(.) in subparagraph 3(a) of this section shall be divided by twelve and the resulting quotient shall be divided by the total number of Residential Customers and Residential Customer equivalents of all Participants for the October- December quarter preceding said July 1st; provided, however, that the monthly rate shall not be less than Two Dollars ($2.00) per month per Residential Customer or Residential Customer equivalent at any time during the period ending July 31, 1972. (c) The monthly sewage disposal charge paid by each Participant to Metro shall be obtained by multiplying the monthly rate by the number of Residential Customers and Residential Customer equivalents of the Participant. An additional charge may be made for sewage or wastes of unusual quality or composition requiring special treatment, or Metro may require pretreatment of such sewage or wastes. An additional charge may be made for quantities of storm or ground waters entering those Local Sewerage Facilities which are constructed after January 1, 1961 in excess of the minimum standard established by the general rules and regulations of Metro. 4. The parties acknowledge that, by resolution of the Metropolitan Council, Metro may impose a charge or charges directly on the future customers of a Participant for purposes of paying for capacity in Metropolitan Sewage Facilities and that such charges shall not constitute a breach of this agreement or any part thereof. The proceeds of said charge or charges, if imposed, shall be used only for capital expenditures or defeasance of outstanding revenue bonds prior to maturity. In the event such a charge or charges are imposed, the City shall, at Metro's request, provide such information regarding new residential customers and residential customer 5 equivalents as may be reasonable and appropriate for purposes of implementing such a charge or charges. 5. A statement of the amount of the monthly sewage disposal charge shall be submitted by Metro to each Participant on or before the first day of each month and payment of such charge shall be due on the last day of such month. If any charge or portion thereof due to Metro shall remain unpaid for fifteen days following its due date, the Participant shall be charged with and pay to Metro interest on the amount unpaid from its due date until paid at the rate of 6% per annum, and Metro may, upon failure to pay such amount, enforce payment by any remedy available at law or equity. 6. The City irrevocably obligates and binds itself to pay its sewage disposal charge out of the gross revenues of the sewer system of the City. The City further binds itself to establish, maintain and collect charges for sewer service which will at all times be sufficient to pay all costs of maintenance and operation of the sewer system of the City, including the sewage disposal charge payable to Metro hereunder and sufficient to pay the principal of and interest on any revenue bonds of the City which shall constitute a charge upon such gross revenues. It is recognized by Metro and the City that the sewage disposal charge paid by the City to Metro shall constitute an expense of the maintenance and operation of the sewer system of the City. The City shall provide in the issuance of future sewer revenue bonds of the City that expenses of maintenance and ope--attonr of the sewer system o! ::. City sh&ii b. paid before payment of principal and interest of such bonds. The City shall have the right to fix its own schedule of rates and charges for sewer service provided that same shall produce revenue sufficient to meet the covenants contained in this Agreement. 6 Section 2, Effective Date o mendmenl. This amendment shall take effect at the beginning of the first quarter following the date first written above with quarters beginning January 1, April 1, July 1, and October 1. Section 3.

Recitals A. Both Algona and Auburn (each a"Party" and collectively '`the Parties") are"public agencies"as defined by Chapter 39.34 RCW,and are authorized by that statute to cooperate on a basis of mutual advantage in order to provide for services and facilities. B. Algona owns and operates a water utility ("Algona Water System") and a sanitary sewer utility Algona Sewer System"),which collectively provide water and sewer service to customers located within Algona's utility service area(s). C. Auburn owns and operates a water utility ("Auburn Water System") and a sanitary sewer utility Auburn Sewer System"),which collectively provide water and sewer service to customers located within Auburn's utility service area(s). D. There are three parcels located within the City limits of Auburn at 1611 West Valley Highway S APN 2321049039), 1743 West Valley Highway S (APN 3751600709) and 1929 West Valley Highway S (APN 3751600711) (collectively, "West Valley Parcels") that are connected to and served by the Auburn Water System, but are also connected to and served by the Algona Sewer System. E. There are four parcels located within the City limits of Algona at 502 Boundary Boulevard(APN 0301510060), 512 Boundary Boulevard (APN 0301510120), 1196 Industry Drive N (APN 0301510190) and a vacant parcel located between 502 and 512 Boundary Boulevard (APN 0301510100)(collectively,"Boundary Boulevard Parcels")that are connected to and served by the Algona Water Utility, but are also connected to and served by the Auburn Sewer System. F. The dissociation between the water and sewer service connections for the West Valley Parcels and Boundary Boulevard Parcels is longstanding and of uncertain origin. To the best of the Parties' mutual belief and understanding, said dissociation may have resulted from various factors, including without limitation the timing of annexation,development and/or utility connection of the underlying properties. G. The water and scwer utility usage of the West Valley Parcels has historically been roughly equivalent to the water and sewer utility usage of the Boundary Boulevard Parcels. H. Each Party's billing and collection for sanitary sewer service usage is based primarily upon water usage, such that each Party may approximately measure, bill and collect for a customer's sewer utility service by measuring the volume of water service provided to that customer. I nterlocal Cooperation Agreement Concerning Water and Sewer Utility Service, Billing, and Collection. 2 1. The significant expense of connecting the West Valley Parcels to the Auburn Sewer System, and of connecting the Boundary Boulevard Parcels to the Algona Sewer System, would be greatly disproportionate to the practical benefits resulting from such connection, which would be nominal. J. The Parties are currently evaluating permanent options to address the issue of water and sewer utility service for the West Valley Parcels and Boundary Boulevard Parcels and will continue to engage in discussions regarding the same as the lines require repair or replacement or as development in the respective area(s) occurs.

These models provide a means to simulate the impact of different sized storms on the collection system and determine where system deficiencies are likely to occur. In addition, a well-calibrated model provides an easy way to test alternative improvement scenarios. This Technical Memorandum summarizes the City of Auburn’s (City) sewer collection system hydraulic model update and calibration for use in the City’s sewer system conveyance planning. 1.2 Existing Service Area The City’s service area is shown in Figure 1.1. The service area contains approximately 17,968 acres. The current service area includes most of the City limits, parts of City of Kent, some unincorporated areas of both King and Pierce County’s, and part of the Muckleshoot Indian Reservation.

The different flow components are described in the section below and illustrated in Figure 1.2. 1.3.1 Dry Weather Flow Components Average dry weather flow (ADWF) is the flow that is always entering the collection system on a daily basis. There are two primary components of ADWF, base wastewater flow (BWF) that is the sanitary flow the system is intended to convey, and dry weather ground water infiltration. ADWF was estimated from an average of dry weather flow (DWF) data at each flow meter from 2020 to 2022. Section 1.4 describes the flow monitoring efforts performed by ADS Environmental Services (ADS), which went into determining the ADWFs. The ADWF serves as the baseline flow in the hydraulic model. Figure 1.2 Typical Wastewater Flow Components Note: This figure is not based on flow data specific to the City. TM 1 - MODEL CALIBRATION REPORT MAY 2024 / FINAL / CAROLLO CITY OF AUBURN 2024 COMPREHENSIVE SEWER PLAN 1-4 1.3.1.1 Base Wastewater Flow The BWF is the sanitary flow generated by routine water usage of the collection system service area residential, commercial, and industrial customers. Conveying this flow is the primary function of the collection system. The flow has a diurnal (24-hour) pattern that varies by individual customer’s water use patterns. Typically, a residential diurnal pattern has two peaks with the more pronounced peak following the wake-up hours of the day, and a less pronounced peak occurring in the evening. Commercial and industrial patterns, though they vary depending on the type of use, typically have more consistent higher flow patterns during business hours, and lower flows at night. Furthermore, the diurnal flow pattern of a weekend may vary from the diurnal flow experienced during a weekday. Diurnal patterns are applied to ADWFs, and cumulatively make up the flows through the wastewater collection system. The diurnal patterns utilized for the City’s collection system basins are developed in Section 1.4.2.1. 1.3.1.2 Dry Weather Groundwater Infiltration Dry weather groundwater infiltration (GWI) will enter the sewer system when the relative depth of the groundwater table is higher than the depth of the pipeline and the sanitary sewer pipe, allowing infiltration through defects such as cracks, misaligned joints, and broken pipelines. Dry weather GWI (or base infiltration) cannot easily be separated from BWF by flow measurement techniques. Therefore, dry weather GWI is typically grouped with BWF. 1.3.2 Wet Weather Flow Components Wet weather flow (WWF) includes two components:  Inflow and infiltration (I/I): The stormwater I/I response in the sewer system to rainfall is seen immediately (inflow) or within hours after the storm (infiltration).  GWI: Wet weather GWI is not specific to a single rainfall event, but instead from effects of saturated soils on the sewer system over the entire wet weather season. The depth of groundwater rising above the pipe invert elevation causes GWI. Sewer pipes within close proximity to a body of water can also be greatly influenced by groundwater effects. 1.3.2.1 Inflow and Infiltration I/I are rainfall derived flows in the collection system from specific storm events. Inflow is stormwater that enters the sewer system via a direct connection to the system, such as roof drain and downspout connections, leaky manhole covers, and inappropriate storm drain connections. Infiltration is stormwater that enters the sewer system by percolating through the soil and entering through foundation drains and sumps inappropriately connected to the system, defects in pipelines, manholes, and joints. Some common sources of I/I are shown in Figure 1.3. The adverse effects of I/I entering the sewer system is increases in both flow volume and peak flows such that the sewer system may operate at or above its capacity, as illustrated in Figure 1.4. If too much I/I enter the sewer system, sanitary sewer overflows (SSO) could occur. TM 1 - MODEL CALIBRATION REPORT MAY 2024 / FINAL / CAROLLO CITY OF AUBURN 2024 COMPREHENSIVE SEWER PLAN 1-5 1.3.2.2 Groundwater Infiltration GWI, one of the components of I/I, is associated with extraneous water entering the sewer system through defects in pipes and manholes while the ground is saturated during the wet weather season. GWI is related to the condition of the sewer pipes, manholes, and groundwater levels. GWI may occur throughout the year, although rates are typically higher in the late winter and early spring in the Pacific Northwest.

The City also obtained flow data from meters within the City that are part of King County’s larger flow monitoring program. The purposes of the flow monitoring program were to collect data for correlating actual collection system flows to the hydraulic model predicted flows, evaluate the system's capacity, and estimate basin I/I. The flow monitoring data was collected for a period of two years of wet season, monitoring from 2020 to 2022. The "Auburn WA 2020-21 Draft I&I Report v1" prepared by ADS summarizes the flow monitoring program and was submitted to the City as a stand-alone report. The report can be found in Attachment 1A. 1.4.1 Program Description 1.4.1.1 Flow Monitoring Sites and Tributary Areas A total of 40 sewer basins were monitored during the flow monitoring period from 2020 to 2022 within the service area, and seven King County meters recorded data within the City. A total of 20 of the meters and all seven of the King County meters recorded data over the first wet season from October 2, 2020 to April 15, 2021. Four meters recorded data from 2020 to 2022. The remaining 16 meters were sub-basin monitoring over the 2021-2022 wet weather season. The remainder of this report will focus on the 22 flow monitoring locations that encompass larger tributary areas and have accurate data for the first wet season period. These meters were selected for calibration and offer the best distribution of data across the collection system and encompass the City’s critical sewered areas. These 22-meter locations are identified in Figure 1.5. Table 1.1 lists the flow monitoring locations that were selected for calibration and the diameters for the associated sewers. Figure 1.6 provides a schematic illustrating all 47 flow monitoring locations relationship to help understand how the basins connect and the time data was recorded at each meter site. Figure 1.7 provides the same schematic showing the meters that were selected for model calibration. Meter data quality was reviewed at all sites and deemed acceptable to use for model calibration. The quality of meter data and other trends in the flow can be determined from scattergraphs, which plot the depth versus velocity as compared to the manning’s curve for the pipe segment. Scattergraphs for each site can be found in the Flow Meter Quality Review, Attachment 1B.

The velocity meter measured water with a Doppler signal and the depth measured with either a submerged pressure sensor or level transducer. Level was converted to area based on the pipe diameter. ADS selected the optimal type of flow meter to use on a site-to-site basis based on the hydraulic characteristics at each site, as well as other factors. ADS conducted an analysis of the data retrieved from each flow meter and made adjustments as needed for calibration based on the field measurements. The flow at each meter was then calculated at 15-minute intervals based on the continuity equation: Q = V x A Where:  Q = Pipeline flow rate, cubic feet per second.  V = Average velocity, feet per second.  A = Cross sectional flow area, square feet. 1.4.1.3 Rain Gauges One rain gauge was installed by ADS to record rainfall that occurred throughout the flow monitoring program and six existing king county rain gauges were used. The location of the rain gauge is shown in Figure 1.5. 1.4.2 Flow Monitoring Results The flow monitoring program data were evaluated by components including DWF, rainfall, and WWF. Data collected from flow meter AUB A-1 is presented throughout this Technical Memorandum as an example of the type of data and the results from the flow monitoring program. Results for all other meters are included in Attachment 1B. 1.4.2.1 DWF Data Base flow can be estimated for a wastewater collection system by comparing DWF and WWF at the flow monitoring locations. To estimate ADWF for more specific areas, such as individual wastewater basins, DWF’s are typically estimated based on the area contributing to flows and flow coefficients developed for each land use type. This method is based on the assumption that areas with similar land uses, such as low-density residential parcels, produce equivalent quantities of wastewater flow on a per area basis. System-wide flows can be compared to known flows at flow monitors to verify accuracy. This method of estimating base flows is an industry standard for planning and provides sufficiently accurate data for planning purposes. TM 1 - MODEL CALIBRATION REPORT MAY 2024 / FINAL / CAROLLO CITY OF AUBURN 2024 COMPREHENSIVE SEWER PLAN 1-12 Existing ADWFs for each basin were estimated using data from the flow monitoring program for each of the flow monitoring basins. ADWF was developed using the driest days from the flow monitoring period based on the following set of minimum criteria:  Less than 0.1 inch of rain in the previous 24 hours.  In addition, those dry days that exhibited unusual flow patterns were not used to generate net dry day flow values for a basin. Characteristic dry weather 24-hour diurnal flow patterns for each site were developed from hourly data. The hourly flow data were also used to calibrate the hydraulic model for the observed DWF’s during the flow monitoring period. Hourly patterns for weekday and weekend flows vary and were separated to better define DWF. An example of the ADWF from Flow Meter AUB A-1, are shown in Figure 1.8. Both gross and net ADWF are developed for each meter data set. Gross ADWF corresponds to the total measured flow at the meter and includes all upstream areas while net basin flows are those associated only with the basin as monitored by its meter of the same name, and therefore excludes all flow from upstream meters (if any).

Four significant rainfall events occurred during the course of the flow monitoring period, as well as a few other relatively minor events. The storms recorded during the flow monitoring program generated an I/I response in the collection system and were appropriate for I/I analysis and model calibration purposes. The hourly flow measured at seven different rain gauges recording rainfall over the course of the flow monitoring program are illustrated in Figure 1.9. Figure 1.10 illustrates the total accumulation of rainfall over the course of the flow monitoring period for the gauges including the ADS tipping bucket type rain gauge (RG41Y). Table 1.3 summarizes the four largest events over the total rainfall period, recorded at the RGAUB rain gauge. The RGAUB rain gauge best represented the rainfall distribution between the gauges and was used in the model for WWF calibration.

Land use determines the area available for various types of development including both single-family and multi-family residential development, as well as commercial and industrial uses that provide the economic base necessary to support residential development. Land use information is an integral component in estimating the amount of wastewater generated within any City. The type of land use in an area will affect the volume of wastewater generated. Additionally, the service area is typically comprised of both sewered and unsewered areas: sewered areas contribute flow to the collection system, while unsewered areas are vacant, undeveloped land, or development such as parks or parking facilities without a wastewater connection and do not currently contribute flow to the collection system. Future land use designations can be different from the existing zoning designations. A relationship between existing and future designations was developed, based on the Comprehensive Land Use Plan. This relationship was expanded based on the City’s geographic information system (GIS) Table 1.4 summarizes the correlation between zoning and land use and was used to develop wastewater flow coefficients.

These relationships, called wastewater flow factors are established based on the average wastewater flow generated for each existing land use type. The land use flow factors were established to project the estimated ADWF through future development of the City’s wastewater collection system and project future flows within the existing service area boundary. Average wastewater flow coefficients are volume rates, usually expressed in gallons per day per acre (gpda), applied to either gross or net acres to calculate average day flow generated from a particular land use type. A flow coefficient was developed for each of the land use classifications that were discussed previously. The flow coefficient provides a means to transform a land use category from acreage into wastewater flow. The resulting flow is then inputted into the appropriate sewer area in the sewer system model. Wastewater flow coefficients for residential areas typically range between 500 to 3,000 gpda, and commercial and industrial areas might range from 1,000 to 4,000 gpda, with typical values averaging approximately 1,500 gpda. Land uses designated as open space and parks are assumed to generate negligible amounts of sewage flow, and as a result have a flow coefficient of zero. Figure 1.13 outlines the portion of the system that is currently considered sewered and contributing flows to the collection system. This acreage is assigned to each catchment in the system and used for rainfall runoff routing. Flow monitoring basins were developed to define the upstream tributary area for each meter selected for calibration, using only connected and developed parcels. Flow factors are applied across these flow monitoring basins to allocate ADWF. Figure 1.14 outlines the flow monitoring basins used for this process.

If the flow coefficients produced average flows that were significantly different from the field measured flows, further investigation was conducted to verify that the tributary basins were delineated correctly and if the collection system configuration was correct.  Once the coefficients for the 22 flow meter tributary areas are balanced, the weighted average of the coefficients for each land use type is calculated based on the acreage contribution from each metering tributary area.  The flow coefficients were then adjusted to balance the calculated flows for the overall developed sewer service area, where flow-monitoring data was available. The weighted wastewater flow coefficients and land use areas that represent existing ADWF are summarized in Table 1.7. The land use coefficients generate an ADWF to the modeled collection system of 7.77 mgd, a -0.5 percent difference from the measured ADWF of 7.81 mgd. Wastewater flow factors were compared to the Comprehensive Plan, Attachment 1C, to confirm they correspond to the densities and allowable dwelling unit per acre for each land use type. This was done at a flow monitoring basin level such that the flow factors matched the relative densities, however when averaged out across the system some flow factors are smaller or larger than the expected density based on the flow monitoring basin the majority of the land use acreage is within. The detailed flow factors at a flow monitoring basin level are shown in Attachment 1D.

Wastewater system models can assess the conveyance capacity of the collection system. The model can be used to size new infrastructure. In addition, sewer system models can perform “what if” scenarios to assess the impacts of future developments and land use changes. The City’s collection system hydraulic model was updated and expanded using a multi-step process utilizing data from a variety of sources. This section summarizes the hydraulic model development process, including a description of the modeled collection system, the hydraulic model elements, and the model creation process. 1.7.1 Selected Hydraulic Modeling Software The City’s previous collection system hydraulic model was developed using the Mike Urban hydraulic modeling software package, developed by DHI. This project converted the model from Mike Urban to Mike+, the current DHI collection system product. The hydraulic modeling engine for the Mike+ software package is now 1D, it was previously MOUSE. The model was updated to use the 1D engine, which is widely used throughout the world for planning, analysis, and design related to stormwater runoff, combined sewers, sanitary sewers, and other free surface drainage systems such as streams and rivers. TM 1 - MODEL CALIBRATION REPORT MAY 2024 / FINAL / CAROLLO CITY OF AUBURN 2024 COMPREHENSIVE SEWER PLAN 1-25 The latest version (2022) of Mike+ was used for the hydraulic model update. More information about the modeling software can be found in the Mike+ Collection Systems Guide 1. 1.7.2 Modeled Collection System and Skeletonization The City provided Carollo Engineers, Inc. with an initial skeletonized model. Skeletonization is the process of identifying the key system conveyance components to include in the model. Smaller pipelines not considered essential for the intended analysis purpose are removed from the modeled set. The purpose of skeletonizing a system is to develop a model that accurately simulates the hydraulics of a collection system, while at the same time reducing the complexity as well as computational run times and to simplify data management. It is common practice in sewer system master planning to exclude small diameter sewers when developing a hydraulic computer model. Key sewers are included in the City’s hydraulic model where needed for connectivity, or where it was determined that the pipes in question were considered as primary collectors. The collection system remains skeletonized for this project, with no increase in modeled system coverage. Pipes were updated to reflect projects and changes that occurred since the last plan. 1.7.3 Elements of a Hydraulic Model The following provides a brief overview of the various elements of the hydraulic model and the required input parameters associated with each:  Nodes (Manhole): Sewer manholes, cleanouts, and other locations where pipes begin, pipe sizes change, or pipelines intersect are represented by junctions in the hydraulic model. Required inputs for junctions include rim elevation, invert elevation, diameter, and surcharge depth (used to represent pressurized systems). Nodes are also used to represent locations where flows are split or divided between two or more downstream links.  Pipes: Gravity sewers and force mains are represented as pipes in the hydraulic model. Input parameters for pipes include length, friction factor (e.g., Manning’s n for gravity mains, Hazen Williams C for force mains), invert elevations, diameter, shape, and whether or not the pipe is a force main.  Nodes (Basin): For collection system modeling, basins are typically used to represent pump station wet wells (although other storage basins, etc., can be modeled as basin). Input parameters for basins include invert elevation, wet well depth, and wet well cross section or a depth-area relationship.  Pumps: Pumps are included in the hydraulic model as links. Input parameters for pumps include pump curves and operational controls.  Nodes (Outfalls): Outfalls represent areas where flow can leave the system. For sewer system modeling, an outfall typically represents an overflow point or the connection to the wastewater treatment plant.  Boundary Conditions (Rainfall): Rain gauges are locations where rainfall is input to the hydraulic model for simulation of WWF. The rain can be historical, projected, or theoretical hourly rainfall events. 1 Mike+ Collection System User Guide, DHI 2022. TM 1 - MODEL CALIBRATION REPORT MAY 2024 / FINAL / CAROLLO CITY OF AUBURN 2024 COMPREHENSIVE SEWER PLAN 1-26  Catchments: Catchments represent areas of land whose topography and drainage characteristics direct flow to a single discharge point into the sewer system. Catchments can be used to define sanitary flows or to route a portion of the rainfall runoff into the system. Inflow conditions for the catchments are defined model inputs. Figure 1.15 outlines all the modeled catchments in the collection system model.  Inflows: There are two primary flow sources that enter into the collection system, which are input through individual junctions (and storage nodes) in the model: » Dry Weather. Dry weather inflows simulate base sanitary wastewater flows and represent the average flow. The DWF can be multiplied by up to four patterns that vary the flow by month, day, hour, and day of the week (e.g., weekday or weekend). The dry weather diurnal patterns are adjusted during the dry weather calibration process to match the known typical daily flow fluctuations. Two diurnal patterns were developed for each basin, respectively representing weekday and weekend days (see Section 1.4.2.1). » Rainfall derived infiltration and inflow (RDII). RDII are flows into the collection system originating from rainfall. Several models are available in Mike Urban to capture these effects. The models have a number of parameters that are adjusted during the wet weather calibration process to model the flows into the collection during different storm events.

Calibrating the model to match data collected during the flow monitoring program ensures the most accurate results possible. The calibration process consists of calibrating to both dry and wet weather conditions. For this project, both dry and wet weather calibration were conducted at the 22 metering sites presented and discussed in Section 1.4:  DWF calibration ensures an accurate depiction of ADWF generated within the existing service area, and diurnal fluctuations.  WWF calibration consists of calibrating the hydraulic model to a specific storm event or events to accurately simulate the peak flow and volume of I/I into the sewer system. The amount of I/I is essentially the difference between the WWF and DWF components. 1.8.1 Calibration Standards The hydraulic model was calibrated in accordance with international modeling recommendations. The Urban Drainage Group (UDG), formerly known as Wastewater Planning Users Group, a section of the Chartered Institution of Water and Environmental Management (CIWEM), has established generally agreed upon principles for model verification. The dry weather and wet weather calibration focused on meeting the recommendations on model verification contained in the “Code of Practice for the Hydraulic Modeling of Urban Drainage Systems,” published by the CIWEM UDG 2), as summarized below. 1.8.1.1 Dry Weather Calibration Standards Dry weather calibration should be carried out for two dry weather days and the modeled flows and depths should be compared to the field-measured flows and depths. Both the modeled and field-measured flow hydrographs should closely follow each other in both shape and magnitude. In addition to the shape, the flow hydrographs should also meet the following criteria as a general guide:  The timing of flow peaks and troughs should be within 1 hour.  The peak flow rate should be within the range of ±10 percent.  The volume of flow (or the average rate of flow) should be within the range of ±10 percent. If applicable, care should be taken to exclude periods of missing or inaccurate data.  The unsurcharged depth should be within ±10 percent or ±4 inches, whichever is greater. 2 UDG, Code of Practice for the Hydraulic Modelling of Urban Drainage Systems, 1st Edition CIWEM 2017 www.ciwem.org. TM 1 - MODEL CALIBRATION REPORT MAY 2024 / FINAL / CAROLLO CITY OF AUBURN 2024 COMPREHENSIVE SEWER PLAN 1-29 1.8.1.2 Wet Weather Calibration Standards For each meter, three separate storms should be simulated with the model. For at least two storms out of the three events from the flow monitoring period, the model-simulated flows and depths should match the field-measured flows and depths within the accepted criteria. The modeled and field flow hydrographs for the calibration storms should closely follow each other in both shape and magnitude, until the flow has substantially returned to DWF rates. In addition to the shape, the flow hydrographs should also meet the following criteria as a general guide:  The timing of the peaks and troughs should be similar with regard to the duration of the events.  The peak flow rates at significant peaks should be in the range of +25 percent to -15 percent and should be generally similar throughout.  Modeled volume of flow should be within +20 percent to -10 percent of measured volume of flow.  The depth of surcharge should be in the range of +20-inches to -4-inches.  The difference between maximum unsurcharged depth should be within the range of ± 4-inches. The UDG recommends that for wet weather calibration, the use of a single calibration period incorporating a number of rainfall events should be considered whenever possible. In other words, if the flow monitoring program captured several back to back storms, it may be preferable to use the back to back storms events as the calibration storms, as opposed to calibrating to two separate storms that have occurred weeks or months apart. Model calibration simulations should be run for a duration long enough that the RDII response is no longer apparent in the measured data. 1.8.2 DWF Calibration 1.8.2.1 Dry Weather Calibration Process The DWF calibration process consists of several steps, as outlined below:  The first step in the calibration process was to divide the City into flowmeter tributary areas. GIS analysis was used to create 22 tributary areas, one for each flowmeter from the flow monitoring program that was selected to be used for calibration. A map showing the locations of each flow monitoring site and their associated tributary area was provided in Section 1.4 and Section 1.6, along with a schematic of the flow meters.  The next step was to define the flow volumes within each area, which was accomplished by applying the flow factors outlined in Table 1.7 to the catchments proportionally based on the distribution of land use types withing the catchment. TM 1 - MODEL CALIBRATION REPORT MAY 2024 / FINAL / CAROLLO CITY OF AUBURN 2024 COMPREHENSIVE SEWER PLAN 1-30  The last step is to create diurnal patterns to match the temporal distribution of flow. A diurnal curve is a pattern of hourly multipliers that are applied to the base flow to simulate the variation in flow that occurs throughout the day. Two diurnal curves were developed for each flow monitoring tributary area, one representing weekday flow and one representing weekend flow. The diurnal patterns were initially developed based on the flow monitoring data and adjusted as part of the calibration process until the model-simulated flows closely matched the field-measured flows. Figure 1.16 shows the calibrated weekday and weekend diurnal patterns for the area tributary to Meter AUB A1. Similar diurnal curves were developed for each of the meters and its tributary area. These additional curves are available in Attachment 1E. Figure 1.16 Example Diurnal Pattern 1.8.2.2 Dry Weather Calibration Discussion Table 1.8 provides a summary of the DWF calibration using the average and daily peak flow results for both weekday and weekend conditions. As shown on Table 1.8, the model-simulated average for all sites are within 10 percent. The peak flows for both weekday and weekend DWF were all within 10 percent, except for meters A3, A7, Y-2, and MSTTR02A. Those four meters showed variability between weekday and weekend volume, but still match for the average day DWF. Attachment 1E contains a detailed DWF calibration summary sheet for each of the 22 metering sites. Each calibration sheet provides plots that compare the model-simulated and field-measured flow data for both weekday and weekend conditions. An example of the dry weather calibration for Meter AUB A1 is shown on Figure 1.17. There is good overall correlation of the field-measured data to the model output results. A total of 18 of 22 meters meet criteria for both level and velocity, indicating a well calibrated model for DWFs. Manning’s n values were adjusted by flow monitoring basin so that modeled levels would better match the measured data. However, even after these changes some levels could not be matched. The Mike 1D engine simulates flow well under these conditions, but level and velocity are less accurate with the Saint-Venant equations meant for free flow conditions. To account for this, the modeled manhole head losses were adjusted for steep pipes throughout the collection system. For pipes with slopes greater than 0.01 or 1 percent, the head loss was defined as weighted inlet energy with a smaller effective area instead of the default Mouse Classic Engelund. This change ignores inlet expansion losses and assumes the energy level in the manhole equals the inlet pipe. Thus, the manhole level is reduced to better match the field measured data for steep slopes. These TM 1 - MODEL CALIBRATION REPORT MAY 2024 / FINAL / CAROLLO CITY OF AUBURN 2024 COMPREHENSIVE SEWER PLAN 1-31 changes moved the levels closer to being in criteria, but the level changes were not significant enough that all these sites could not be moved into calibration criteria. All 4 meters outside of criteria had higher modeled levels than measured level. Meter A6, A7, Y-2, are all meters located on steep pipe slopes where a hydraulic jump is occurring. These sites are also at points where the pipe size is transitioning. The monitoring at Site A6 was done at a manhole that transitions from a 12-inch to a 30-inch, site A7 was done at a manhole that transitions from an 18-inch to a 36-inch, and Y-2 is where 14-inch transitions to a 24-inch. The modeled levels are exported at the downstream end of the pipe in the monitoring manhole where the hydraulic grade line (HGL) is governed by larger diameter downstream pipe, leading to higher levels than measured. These three sites remained out of criteria for WWF as well. Site AUBRN53 was also slightly out of criteria but moved into criteria during WWF’s so this was deemed less of a concern.

The WWF calibration process consists of running model simulations of historic rainfall events based on data collected as part of a system flow monitoring program. The goal of any WWF monitoring program is to capture and characterize a system’s response to a significant rainfall event, preferably during wet antecedent moisture conditions. As outlined below, the WWF calibration process consists of several elements:  Identify calibration rainfall events. The selection of a particular calibration storm or group of storms is based on a review of the flow and rainfall data. There is a good range of different event types available for the different meters. Major rainfall events that were used as calibration rainfall events were identified as part of Section 1.4.2.2. Table 1.3 summarizes the four storms picked for calibration for each of the 2 sites. The use of a single calibration period incorporating a number of rainfall events was considered whenever possible. All meters except for WINT003, MSTR002A, and AUBRN53 used the first three storms, those three used the 4th event due to meter availability. Figure 1.9 illustrated the storms used in the model calibration process. TM 1 - MODEL CALIBRATION REPORT MAY 2024 / FINAL / CAROLLO CITY OF AUBURN 2024 COMPREHENSIVE SEWER PLAN 1-33  Define RDII tributary areas. For the WWF calibration, RDII flows are added on top of the DWF. The model calculates two types of response: a slow response corresponding mainly to infiltration, or slow response curve (SRC), and a fast response corresponding mainly to direct inflow, or fast response curve (FRC). Imperviousness is the fraction of the catchment area that is impervious and connected to the collections system, generating the FRC runoff, and rainfall derived infiltration (RDI) Area, which is the fraction of the total catchment area that contributes to the SRC. The imperviousness and RDI runoff component are two major model-specific data in the model calculation of WWFs, and each have a number of subparameter components that are adjusted to tune to response timing. These area values were initially set based on engineering judgment, as well as the previously used values, and then adjusted until the model-simulated wet weather flow volume roughly matched the field-measured flows.  Create I/I parameter database and modify to match field-measured flows. The main step in the WWF calibration process involves adjusting both Model A and RDI parameters for each flow monitoring tributary area. Figure 1.18 provides a schematic of the RDI model used. Attachment 1F summarizes all calibrated parameters by flow monitoring site, for current conditions. As with the dry weather calibration, the wet weather calibration process compared the meter data with the model output. Comparisons were made for average and peak flows as well as the temporal distribution of flow until flows returned to their baseline levels. According to the CIWEM UDG, a hydraulic model is generally considered calibrated to WWF conditions if the modeled peak flows are within +25 percent to -15 percent of the field-measured data, and if the average modeled volumes are within +20 percent to -10 percent of the field-measured data. Calibration was performed for the depth of flow as well, this is considered calibrated when peak depths are with ± 4-inches when unsurcharged, and +20-inches to -4 inches when surcharged.  Adjust model variables to match field-measured velocity and flow depths. Once the model- simulated flows matched the field-measured flows within the acceptable limits, the model-simulated velocity and flow depth were compared to the field-measured velocity and flow depth. Adjustments were made to various model parameters until the modeled and measured velocity and depth closely matched one another. The primary varied parameters for this process are node head losses and pipeline roughness (Manning’s n), although other parameters can also be adjusted as calibration results are generated. Sediment buildup and movement in the pipe will also influence the level and depth, but these are very difficult to quantify and can change frequently, therefore they are not included in the calibration. Manning’s roughness coefficients, or n values, have industry accepted ranges based on a number of variables. Roughness coefficients increase over time depending on the construction methods, installation quality, system maintenance, and other environmental factors. There can be certain factors within the City’s collection system that can result in roughness coefficients that differ from the typical range. These could include joint misalignment, cracks, and debris (e.g., root intrusion, etc.) that lead to increased turbulence in a pipe and an increase in the apparent Manning’s n factor. If the model is unable to reasonably match the field-measured flow depth and velocity within the acceptable range of Manning’s roughness coefficients, further investigation should be conducted to help determine the cause of the discrepancy. Some issues that could cause such a discrepancy can include errors in the slope or diameter of a pipeline, downstream blockages, pipeline sags, and, in some cases, influences from downstream pump station operations.

The modeled outputs at each flow meter were compared to the data from three storms recorded during the flow monitoring period for calibration. Each calibration sheet provides plots that compare the model- simulated and field-measured flow, velocity, and level data for the calibration storms. An example of the wet weather calibration for Meter AUB 1A is shown on Figure 1.19. Table 1.9 provides a summary of the WWF calibration using the total volume and peak flow results. Of the 22 meters, 21 had two or more storm event responses within calibration standards for volume and peak flows. Meter A12 was the only site outside of criteria for volume, peak still matched, and this was due to abnormal DWF data during the WWF calibration period. As shown on Table 1.9, the model-simulated average and peak flows at all other meter sites were within the acceptable tolerances for the calibration storms, and therefore the model was considered calibrated and ready to use for capacity analysis purposes. TM 1 - MODEL CALIBRATION REPORT MAY 2024 / FINAL / CAROLLO CITY OF AUBURN 2024 COMPREHENSIVE SEWER PLAN 1-35 As discussed in Section 1.8.1, it is critical that the hydraulic model is not only calibration to volume and peak flow, but also level data. This will ensure accuracy and trust in modeled results when evaluating capacity deficiencies; which are based on a HGL criteria in the collection system. Modeled data at almost all meters closely matched the recorded level information, of the 22 meters with level data, 18 met the level calibration standard. Meters A6, A7, and Y-2 did not meet the level criteria during DWF either and are discussed in Section 1.8.2. Meter Y-1 fell out of level criteria for WWF. The measured data indicated backwatering and surcharging effects during the latter two storm events, and this surcharging was not replicated in the model. This meter is located right upstream of the Green River Siphon, indicating potential sediment buildup constricting flows in the field, and not replicated in the model. 1.8.3.3 Hydraulic Model Calibration Summary Calibration of the City’s hydraulic model was a multi-step process that involved comparing model- simulated flow to the actual field-measured data for both dry and wet weather conditions. The model met all flow CIWEM standards for ADWF and most standards for level. Results showed the model met CIWEM standards for calculation of flows during peak wet weather flow. The CIWEM level standards were met at 18 of the 22 sites used for model calibration. For the meters outside of level criteria, 3 of the 4 meters were over predicting levels, offering a conservative approach for system analysis. These calibration results provide a high level of confidence in the model’s accuracy such that the model can be considered calibrated and ready to use for subsequent capacity analysis.

ADS Environmental Services (ADS) was retained by the City of Auburn to conduct a Rainfall  Dependent Infiltration Inflow (RDII) analysis of its sanitary sewer system.  The scope of the  study was to characterize dry weather and wet weather flow conditions at twenty‐four (24)  temporary flow metering locations and six (6) King County permanent flow meters.  One  temporary rain gauge and two King County rain gauges were used for rain data.    The metering period was from 2 October 2020 through 15 April 2021.  This metering period is  characterized as a generally dry October following by a rainy winter.  A total of 13 storms were  analyzed.  Two storms on 2 January and 11 January exceeded 3 inches of rainfall, but only one  sewer surcharged (Y‐1) and the rest of the sewers barely reached half full.  It appears that snow  melt affected the 14 February storm.  Section 2.3 discusses the rainfall in more detail.   When the two sets of flow data were first integrated, there was large flow imbalance between  the most downstream Auburn meter (A2) and the four upstream meters, two of which were  King County meters.  ADS discovered nearly a half‐inch difference in the pipe size and King  County found a depth sensor offset of over one inch at meter MSTTR02A.  After both  corrections were made, a small positive balance exists, but it is suspected that the King County  meter WINT003 is still reading a bit high.    RDII volumes are normalized two ways in this report; Capture Coefficient (Percent rainfall  entering sewers) and Gallons per LF of sewer per inch of rainfall.  In a third method basins are  ranked by RDII volume expected from a 2.4 ‐inch storm applied to the Q vs. i relationship  generated at each sewershed.  Historic King County DDF (Depth Duration Frequency) data  indicate that a 5‐year, 24‐hour storm is 2.4 inches.        4      Figure 1 is a schematic layout of the metering network including the six King County meters.  A  diversion exists at SRT11 that conveys all flows to the west and it is believed that all the flow  occurring during this metering period followed that path.

The following sections address the steps followed to conduct the dry‐day and the RDII analyses.   These steps include determining the basin size and performing a quality check on the  wastewater produced by each basin.  Rainfall data are examined and RDII is calculated.     2.1 ‐ Basin Size The size of each basin in Acres and length (LF) of  public sewer was determined using the City’s GIS  information and the sizes are listed in Table 1.   Appendix A is a map showing the basin boundaries  used to determine basin sizes.  There are two  reasons to keep track of basin size.  The first use is  to 'normalize’ the flow measurements by basin size  to produce an apples‐to‐apples comparison of RDII  severity.  Secondly, the basin size has value in  interpreting RDII severity.   Large basins will exhibit  RDII severity close to the system wide average and  small basins will exhibit RDII severity much higher  and much lower than the system average.  If there  are upstream meters, the basin size is the area

  2.2 – Average Dry Day Flow (ADDF)   A first step in conducting an RDII analysis is to determine Average Dry Day Flow (ADDF) at each  metering location and this information is used in two ways. The first is that the ADDF is  subtracted from the flow measured during a storm and the difference is RDII.  The second is  that the shape of the ADDF hydrograph is used to estimate what portion of the ADDF is  wastewater production (WWP) and what portion is base infiltration (BI).    Early in the analysis of RDII data it was observed that there were two distinctly different rain‐to‐ RDII relationships; a Summer season ending 6 November and Winter which is the rest of the  metering period.  This distinction is common and is a function of vegetation; either actively  growing or dormant.  Figure 2 shows the hydrograph for the AUB_Y‐1 meters with selected dry  days shown by the vertical shaded green (weekday) and blue (weekend) bars.  Summer days are  in October and winter days are in April.       Figure 2 Selected Dry Days are shaded in green (weekday) and blue (weekend).  7    For each meter the ADDF is decomposed into the two components of wastewater production  (WWP) and base infiltration (BI) as shown in Figure 3.  In this case the summer weekday value is  0.324 mgd (324,000 gallons per day) and winter weekday is 0.335 mgd.  The estimated base  infiltration (BI) is based on the shape of the weekday ADDF hydrograph and is shown as the red  horizontal line at 0.082 mgd.  The percent of base infiltration at this site is 0.082 mgd/0.324  mgd or 25% base infiltration.                  Figure 3 Average Dry Day Diurnal Curves for Weekdays and Weekends  0.00 0.05 0.10 0.15 0.20 0.25 0.30 0.35 0.40 0.45 0.50 0 3 6 9 12 15 18 21 Dry Weather

leaking water lines, leaking plumbing fixtures and springs.  It may be a seasonal phenomenon as  rainfall affects ground water levels, but generally remains relatively steady over weeks and  months.  The most rigorous method for determining the quantity of base infiltration originating  in a basin is to determine the quantity of potable water flowing into each building within the  basin and subtract it from the measured sewer flow coming out of the basin.  This is an  expensive and sometimes difficult exercise and usually is not done for a short‐term flow  metering study.    For this analysis an empirical method for estimating base infiltration was used.  The method is  borrowed from the potable water industry, which has estimated that the rate of residential  water usage during the overnight hours is approximately 12% of the daily average use.  This  empirical method provides an estimate of the average wastewater production (WWP) in a Basin  based on the average flow (Qavg‐D) and minimum flow (Qmin‐D) of the average dry day  hydrograph.   Subtracting WWP from Qavg‐D provides an estimate of base infiltration (BI).  The equations to  estimate WWP and BI are listed in Equations BI 1 and BI 2.  Equation BI 1  𝑊𝑊𝑃 ൌ ሺ𝑄௔௩௚ି஽ െQ୫୧୬ିୈ ሻ 𝑋  Where; X = .88 (from potable water use records)  Equation BI 2  𝑄஻ூ ൌ𝑄௔௩௚ି஽ െ 𝑊𝑊𝑃    In concept, this method generates an estimate of WWP based on the difference between  average flow and minimum flow.  As base infiltration varies over the year the difference  between average and minimum flow (and WWP) is expected to remain constant.  This method  of estimating is reliable for residential neighborhoods with sewer basin sizes on the order of  20,000 LF.  A refinement to this empirical method, the Stevens/Schutzbach equation, uses a curve fitting  technique to increase the reliability of the BI estimation at meters with higher flows.  As sewer  sheds become larger with longer travel times, the normal dry day hydrograph flattens, which in  turn affect the minimum to average relationships.  Equation BI 3 is the Stevens/Schutzbach  equation that was used to estimate base infiltration in all Basins.  Qavg‐D is the average flow and  MDF is the minimum flow of the dry day hydrograph.  Equation BI 3  Stevens/Schutzbach Equation

residential flow patterns.  Reliability decreases in non‐residential basins and in basins where the  flow meter measures flow from cycling pump stations.  Although there are several limitations,  this method is considered the best for estimating BI in residential areas using only flow data.  In  commercial or industrial areas this method can produce unreliable results.    Figure 4 is a graph of the gross average dry day flow (ADDF), the wastewater production and  base infiltration at each meter.  The term, “gross,” refers to the meter measurement prior to

Analysis   This rainfall analysis looks at the total rainfall recorded by each rain gauge for each storm and  looks at the maximum return frequency for each rain gauge and each storm.  There were  thirteen storms that were analyzed.  Selecting a storm in King County during the winter is  subjective because of the frequent but small amounts of rainfall.  Selecting a storm is a balance

rainfall with saturated soil conditions.  The threshold values with be lower in the summer and  fall when vegetation is actively taking up moisture and after a long dry period with low soil  moisture.  This study was conducted in both low antecedent moisture conditions in October  and November and higher moisture condition later in the metering period.   Figure 9 shows RDII normalized by sewer length (Gal/LF/inch) and sorted on the 2 January  storm.  For severity normalized by length, a general rule of thumb is that sewersheds in the  winter/spring with values less than ~10 to 12 Gal/LF/Inch do not have excessive RDII, values up  to 20 Gal/LF/Inch are marginal and values over 20 Gal/LF/Inch are considered excessive.  In low  moisture conditions values greater than 10 Gal/LF/inch may be considered to fall within the  ‘marginal’ range.  The AUB_A2 basin should be discounted because of the balancing problem  and the 2 Feb storm should be discounted because of the snow melt.           Figure 9 RDII Severity in Gallons/LF/Inch  0 5 10 15 20 25 30 35 Rainfall Dependent Inflow/Infiltration Gallons/LF/Inch

A third method is to apply a design storm to the Q vs i plots for each basin.  Figure 11 displays  the Q vs. i plots of RDII volume vs. rainfall for AUB_A9 for each storm separated into seasons.   Each data point on this plot is composed of the RDII volume measured during each storm and  the rainfall that fell during the storm.  In the top plot a 2.4‐inch (5‐yr., 24‐Hr) storm is applied to  the regression line resulting in a predicted RDII volume of just over 0.24 MG.  Because the snow  melt storm of 14 Feb should not be included here, it was removed to generate the bottom plot.   The results did not change much, and the projected RDII volume is 0.24 MG.  Appendix C  includes this plot minus the 14 Feb snow melt storm for each basin.

the last column on Table 3 and are ranked.  The R2 column is the correlation coefficient and  values less than 0.7 are less reliable and the user should be cautious about using the projected  values.  Poor correlations can be due to non‐uniform rainfall or some data issue.  For example,  the flow from AUB_A11 was shallow and erratic and the RDII was low.    There is not a definitive way to determine when RDII is ‘too much’, but a rule of thumb is that  values greater that 10 gal/LF/Inch or so are probably in the range that deserves attention.  But  Keep in mind that larger basins appear to have lower severity than many smaller basins.  Basins  Y‐2 and Y‐3 are two largest sewersheds in the Auburn system and generated the most RDII of all  the Auburn sewersheds but fall below the rule of thumb for severity.       Table 3 Projected RDII Volume in Millions of Gallons from a 2.4‐inch storm.  Meter # Storms R 2 X Intercept Slope MG Gal/LF

Capacities Operational capacity is the actual flow that a pipe can carry as opposed to the theoretical capacity based  on pipe slope and roughness of the pipe section in which the meter is installed.  The technique  for this analysis is to plot a depth‐velocity scattergraph of the meter data upon which are also  plotted a pipe curve (Lanfear‐Coll [Manning] or Stevens‐Schutzbach) and Iso‐Q lines.  The  technique requires that the pipe fill to around 80% full so that hydraulic behavior can be  observed.  As it turns out only one pipe reached more than 60% full and that was AUB_Y‐1 at  the Green River siphon and it surcharged to 24 inches.  Figure 13 is a scattergraph of meter  AUB_Y‐1 it shows a Theoretical Capacity of approximately 4 mgd and the Operational Capacity  of 0.8 mgd circled in red.  It surcharged during the 2 Jan and 11 Jan storms.   In this case both the Lanfear‐Coll and the Stevens‐Schutzbach curves are plotted.  What is  observed here is that the theoretical capacity, as established by the Stevens‐Schutzbach curve  is around 4 mgd in this 17.5‐inch pipe.  However, the actual data show that the sewer enters  backwater at around 7 inches of depth and carries around 0.8 mgd throughout the surcharge to  around 24 inches.  There is a distinction in hydraulic conditions based on how data behave  relative to the Iso‐Q lines.  Data will adhere to an Iso‐Q line if there is a ‘Hard restriction’  downstream such as an under‐sized pipe or a siphon.    GIS data indicated there is a double barrel siphon downstream of this meter with 8‐inch and 12‐ inch barrels.  However, the scattergraph pattern reveals that only one barrel is active.   Scattergraphs for all sites are included in Appendix B.     .    Figure 13 Scattergraph reveals both Theoretical and Operation Capacity of the sewer. 21    4.0 – Subjective Views of Hydrographs   In addition to the numerical analysis in this report we have plotted storm hydrographs for the  eight largest storms at each meter in Appendix B.  It is noticeable that there appear to be minor  sources of Inflow during high intensity storms of October as shown in Figure 14.  The gold RDII  hydrograph follows the rainfall hyetograph very closely indicating that the RDII is the direct  result of rainfall, a classic inflow source such as a roof drain.  This hydrograph is in 15‐minute  time steps, but the observations can easily be made in the 60‐minute plots in Appendix B.

On the other hand, the hydrograph from AUB_A2 in Figure 15 reveals a sewershed that does  not include many ‘spikes’ from sources of Inflow, but does reflect dramatic influence of base  infiltration as the soil moisture increases and declines slowly over the wet season.               Figure 15 Sewershed AUB_A3 experiences RDII more similar to infiltration rather than inflow.  23    5.0 – Conclusions   1. By design this metering period captured the traditional dry weather period in October  and the wet season beginning in November.  Five storms recorded a return frequency of  at least one year in at least one rain gauge.  Two January storms exceeded 3 inches of  rainfall.     2. The sewer system handled these storms readily with only one sewer surcharging and  that was due to the restricted flow at a downstream siphon.  The Green River siphon at  AUB_Y1 is shown to have an 8‐inch barrel and a 12‐inch barrel, but the scattergraph  indicates that only one barrel was functioning.     3. The wide range of basin sizes between the larger ‘Y’ basins and the smaller ‘A’ basins is  what would have been expected.  The ‘Y’ basin generated the most RDII, but RDII  severity of the smaller basins was both higher and lower than the ‘Y’ basin.  The intuitive  observation about severity should be avoided; “The large basins don’t look so bad”.    4. Many of the ‘A’ basins performed well with small RDII contributions, but some ‘A’ basins  experience minor sources of Inflow.     5. The RDII severity calculations are low compared to what is often experienced in other  collection systems.        24      Appendix A – Sewershed Map Appendix B ‐ Sliicer Graphics Appendix C – Q vs i Plots 4455 S. 134th Place Tukwila, WA 98168 206-762-5070 www.adsenv.com City of Auburn Auburn, WA King County City of Auburn Final Report Submitted to the City of Auburn May 28, 2021 2 Tuesday, September 22, 2020 to Wednesday, April 14, 2021 May 28, 2021 Bob Elwell City of Auburn Sewer Utility Engineer 25 West Main Street Auburn, WA 98001 SUBJECT: Auburn Temporary Flow Monitoring Report Dear Bob, ADS is pleased to submit this temporary flow monitoring report for the city of Auburn.

We take pride in the quality of our built environment as well as the beauty and function of our natural environment. Land use patterns are supported by a complete and efficient transportation and utility infrastructure system. Neighborhoods, commercial centers, and parks are attractive, interesting, accessible, and well maintained. Natural riv- erine and forested corridors are interspersed throughout the city, offering sanctuaries where fish and wildlife reside, and providing opportunities for people to observe and learn about the environment. Residents have a strong association with their neighborhoods, and are engaged and involved in the decisions that steer Auburn into the future. Conditions and trends dispersed land use Pattern For the first 100 years of Auburn’s existence, the land use pattern developed in a relatively logical manner. Auburn was fully contained to the valley floor with a traditional downtown urban center, several north/south heavy commercial and in- dustrial corridors paralleling Highway 167, and a surrounding housing stock that was built primarily between 1910 and 1960. In the last 30 years, the land use pattern of Auburn has changed, primar- ily from incorporation of areas to the south, east, and west. Each newly incorporated area has its own identity and land use pattern. disconnected Communities Because a significant portion of today’s Auburn was settled prior to incorporation, the basic land use patterns and infrastructure have already been established. Furthermore, much of today’s Auburn land use pattern was established in either Auburn, the Muckleshoot Reservation, or prior to incorporation in King County or Pierce County. Given the mix of jurisdictional oversight, myri- ad land use policies, regulations, infrastructure standards, and investments have been applied in these areas. This has resulted in a relative- ly uncoordinated and random land use pattern. It also means that the various communities lack connectivity to each other, have a mix of identi- ties, and are experiencing a change in their char- acter from rural to more urban. Robust diversity of land use Auburn has a strong mix of housing and indus- try. Auburn’s residential land use pattern includes a variety of densities, ages, and housing type. Auburn’s nonresidential land use pattern includes a mix of local and regional retail, entertainment, services, manufacturing, warehousing, and distri- bution centers. This mix of land use is a strength because it exemplifies social, economic, and cul- tural diversity. diversity in natural Resources Auburn’s natural resources include the Green River and its tributaries, the White River and its tributaries, a robust inventory of wetlands, flood- plains, steep slopes, and mature open spaces. With a strong base to work from, the City and its partners can be strategic about how to better connect and preserve natural areas so that the overall system is enhanced for future generations to enjoy. introduCtion All land within the City of Auburn is assigned a land use designation, which builds off the past Comprehensive Plan Map, the existing land use City of Auburn Comprehensive plAn LU-2Vol. 1pattern, previously approved subarea plans, to- pography, natural features, and targeted goals for shifting the character of specified areas. This chapter provides a description for each designa- tion, general criteria for how to assign the desig- nation, and a series of policies that govern land use within each designation. The Comprehensive Plan Land Use Map contained in the Core Comprehensive Plan shows the location and boundaries for each designation. This map should be consulted together with the written policies of this Plan when decisions about zoning desig- nations, land use activities, and development of public infrastructure are considered. This Section of the document also explains the reasoning and intention behind the Plan Map’s land use designations. This should be useful in: • developing and implementing tools (such as zoning provisions) • interpreting the Plan Map as it applies to spe- cific regulatory decisions or development proposals • adjusting or amending the Plan Map when changing conditions or land use markets warrant • planning for public services and infrastructure Finally, this chapter sets forth special policies in- tended to address the unique challenges and opportunities of specific locations within Auburn. These specific policies supplement the general goals, objectives and policies found elsewhere in this plan. r esidential l and use designations Character s ketch Residential uses will comprise a diverse arrange- ment of multiple densities. The pattern of one sin- gle density in a zone or neighborhood will evolve into increased and mixed densities in exchange for amenities that enhance quality of life. There will be greater connectivity and stronger spatial relationships between neighborhoods through strategic locations of roadway, trail, park, and neighborhood-serving businesses. These ameni- ties will help create localized identity while also linking one area to another. The design and build quality of new construction and infill will be held to a high standard. The City will encourage proj- ects to be unique, innovative, and provide the res- idents of Auburn true choice. Values Character: Residential neighborhoods will include amenities, features, and layouts that promote in- teraction amongst residents. Wellness: The design of residential neighborhoods will emphasize safety and nonmotorized connectivity. Service: Through outreach and engagement, in- dividual residents and homeowners’ associations are connected to and aware of municipal servic- es, events, and activities. Economy: Neighborhoods have a physical and personal connection to Auburn’s commercial centers and attractions. People want to move to Auburn because of the commercial and recrea- tional opportunities it has to offer. Celebration: Districts and neighborhoods are identified, promoted, and celebrated. Environment: The built environment will fit into the natural landscape in a way that protects and respects ecosystem function and that preserves native vegetation and soils. Sustainability: Natural resources, economic pros- perity, and cultural vibrancy are balanced in a way that builds and maintains a thriving and long-lasting community. General Policies LU-1 Regulations for new developments and infill should address the following elements: a. Connectivity by multiple means to ad- jacent subdivisions, nearby commercial hubs, and parks and recreation facilities. b. Relationship to nearby existing or future transit service. c. Usable community amenities and spaces. d. Environmental protection and preserva- tion of natural features. e. Preservation of areas that can support low-impact development techniques. land use element LU-3 Vol. 1f. Promote the use of energy and water conservation measures g. Efficient and effective delivery of utility service. h. Innovative design. i. Crime prevention through environmen- tal design. j. Long-term maintenance considerations. LU-2 As the market and availability of util- ities enable denser development to occur, standards should be developed to maximize density while preserving open space and critical areas. LU-3 Programs should be implemented to improve the quality of low-income neighborhoods and encour age reha- bilitation of deteriorating structures and facilities. LU-4 Public and institutional uses may be permitted as a conditional use if de- signed in a manner that enhances the residential character of the area. Special care shall be given to ensur- ing adequate parking, landscaping, and traffic circulation to avoid conflict with residential uses. LU-5 New residential development should contribute to the creation, enhance- ment, and improvement of the trans- portation system, health and human services, emergency services, school system, and park system. This may be accomplished through the develop- ment of level-of-service standards, mitigation fees, impact fees, or con- struction contributions. LU-6 Cluster development is the preferred form of residential development in all residential designations with the goal of preserving natural areas, critical areas, and areas that sup- port low-impact development. Where clustering accomplishes these objec- tives, it should not come at the ex- pense of lost development potential. Variances to lot size, lot dimensions, building height, and other bulk or di- mensional standards should be uti- lized in order to create incentives that promote preservation. Residential Conservancy designation Description This designation should consist primarily of low-density residential uses (one dwelling unit per four acres is allowed) and accessory agricultural uses in areas featuring environmental constraints or requiring special protection such as the Coal Creek Springs watershed area, low-lying areas along the Green River, and areas that are isolated from urban services. This designation will serve to both protect environmental features and hold areas for higher density development until such time public facilities become available. Designation Criteria 1. Areas with significant environmental con- straints, intrinsic value, or that may pose en- vironmental hazards if developed, such as areas tributary to public water sources; 2. Affords greater protections to environmental features than existing designation; 3. Level of service for property consistent with adjacent residential conservancy properties; or 4. Location, size of properties, and character is consistent with a residential conservancy use. Implementing Zoning Designations Residential Conservancy Policies LU-7 Densities and activities shall be of a very low intensity and shall not compromise en- vironmental and watershed resources. LU-8 In addition to single-family homes, these larger properties can also be developed with garages, accessory dwelling units, barns, and other accessory outbuildings. Home occupations, agricultural uses, and other allowed nonresidential activities may City of Auburn Comprehensive plAn LU-4Vol. 1operate out of any type of permitted build- ing, subject to intensity and use limitations. LU-9 Until these areas are served by public util- ities (water, sewer, storm services), exist- ing and new development is not expected to be served by public infrastructure, such as urban streets, curbs, gutters, sidewalks, street lighting, and landscaping. LU-10 As the market and utility availability enable denser development to occur, standards should be developed to maximize density while preserving open space and critical areas. LU-11 Small-scale agricultural uses are allowed and encouraged. Commercial activities that are directly related to and support agricultural uses may also be allowed. The procedural standards may vary depend- ing upon the type and scale of agricultural uses and supporting commercial activities. Small-scale agricultural uses are allowed and encouraged. LU-12 Land use standards should adequately limit and control excessive accumulation of de- bris. Where a permitted activity does allow outdoor storage, it should be adequate- ly screened from adjacent properties and roads, as well as ensuring adequate soil and environmental protection. LU-13 Public, institutional, and resource-ex- tractive uses that are low-intensity and preserve the environment may be consid- ered conditional uses. single-Family Residential designation Description This designation is the predominant land use category in the City. Maintaining and creating a diverse arrangement of interconnected subdivi- sions, neighborhoods, and communities that have a mix of densities and housing types; linkages with other residential areas and commercial hubs through nonmotorized modes, such as pedes- trian and bicycling, and vehicular modes will be encouraged. Designation Criteria 1. Previously developed single-family residen- tial areas; 2. Undeveloped areas that do not meet the designation criteria for other Residential, Commercial, Industrial, Institutional or Public/Quasi-Public designations; or 3. Residential Conservancy areas that contain limited critical areas, are served by public utilities (water, sewer, storm services), and meet the development parameters of the sin- gle-family designation. Implementing Zoning Designations R-1 Residential Zone (One Dwelling Unit Per Acre): All properties located within the Urban Separator Overlay are zoned R-1, as consistent with King County County-wide Planning Policies. R-5 Residential Zone (Five Dwelling Units Per Acre): All properties not located within the Urban Separator Overlay may be zoned R-5. R-7 Residential Zone (Seven Dwelling Units Per Acre): All properties not located within the Urban Separator Overlay may be zoned R-7. Policies LU-14 Accessory dwelling units should play an in- tegral part of promoting infill development and affordable housing, and are therefore encouraged within this land use category. LU-15 Home occupations, bed-and-breakfasts, day cares, and other appropriate uses should be encouraged as viable accessory uses. LU-16 Manufactured homes shall be permitted on single-family lots provided they are sited and constructed in a manner that would blend with adjacent homes. LU-17 Provide a variety of housing typolo- gies to suit the needs of various potential residents. LU-18 Density bonuses outside of the Urban Separator Overlay should be approved based on innovations in transportation, stormwater management, and public amenities proposed for the development or adjacent neighborhoods associated land use element LU-5 Vol. 1with the request. The onus is on the de- veloper to justify density above baseline. Examples of amenities and concepts that justify density bonuses include park space, art, enhanced landscaping, trails that con- nect to adjacent properties, neighborhood commercial property set asides, use of low-impact development techniques be- yond the minimum code requirements, in- corporation of CPTED concepts, and varia- tion of architecture and housing typology. moderate density Residential designation Description Moderate Density Residential designated areas are planned to accommodate a variety of res- idential dwelling types. Varying intensities may be permitted to provide a transition between sin- gle-family residential and other more intensive uses or activities (such as arterial streets) based on adjacent density, intensity, and/or charac- ter. Appropriate densities in these areas gen- erally range from 7 up to 20 dwelling units per acre. Dwelling types generally range from sin- gle-family dwelling to multiple-family dwellings, with larger structures allowed (within the density range) where offsetting community benefits can be identified. Designation Criteria 1. Previously developed moderate-density res- idential areas; or 2. Areas that provide a transition between sin- gle-family and multifamily, single-family and nonresidential, multifamily and nonresidential zones or development that are adjacent and meet the development parameters of the Moderate Density Residential designation. Implementing Zoning Designations Residential Transition R-10 Residential (Ten Dwelling Units Per Acre) R-16 Residential (Sixteen Dwelling Units Per Acre) Policies LU-19 Density bonuses and flexible development standards should be considered an incen- tive for innovative neighborhood design. LU-20 Carefully developed low-intensity of- fice, or residentially related commercial uses (such as day care centers) can be compatible. LU-21 Accessory dwelling units should play an integral part of promoting infill devel- opment and affordable housing and are therefore encouraged within this land use category. m ultiple-family designation Description This category shall be applied to those areas that are either now developed or are reserved for mul- tiple family dwellings. Densities may range from 20 to 24 units per acre. These communities are served by transit, have nonmotorized connections to surrounding amenities and services, or have access to on-site amenities. Designation Criteria 1. Previously developed high-density residen- tial or manufactured/mobile home parks; or 2. Properties that are connected to single-fam- ily and nonresidential designations by the Residential Transition designation and meet the development parameters of the Multifamily designation. Implementing Zoning Designations R-20 Residential Zone (Twenty Dwelling Units Per Acre): All Multiple-family designated land not previously developed as manufactured/mobile home parks are zoned R-20. Manufactured/Mobile Home Park: All previously developed manufactured/mobile home parks are zoned RMHC. Policies LU-22 Development regulations should include density bonuses and flexible development standards that create incentives for inno- vative site and building design, incorpo- ration of open space and public art, non- motorized connectivity to parks and com- mercial areas, proximity to transit services, City of Auburn Comprehensive plAn LU-6Vol. 1supplemental natural resource protection, supplemental use of CPTED, and supple- mental use of low-impact development techniques. LU-23 Home occupations and shared housing should be allowed in this designation; how- ever, given their high densities, it is appro- priate to establish additional restrictions, procedures, and requirements in order to ensure that they are compatible with their surroundings and do not adversely affect the community. LU-24 Live–work units are encouraged. LU-25 Improve the quality of low-income neigh- borhoods and implement programs that encour age rehabilitation of deteriorat- ing structures and facilities the downtown area, areas between lower-density resi- dential uses and more intense nonresiden- tial activities, and areas with high levels of transit service and available high-quality services. LU-26 Multiple-family development should be subject to building and site design stan- dards. These standards should address the appearance of buildings, compatibility with nearby uses, exterior lighting, con- nectivity with surrounding properties and uses, the relationship of ground floor spac- es and entryways with the streetscape, and connectivity to nearby nonresidential hubs (shopping centers and schools). LU-27 Provide a variety of housing typolo- gies to suit the needs of various potential residents. LU-28 Establish intensity limitations such as floor area ratios, density, building height, cover- age ratios, setbacks, and other standards. LU-29 Access to nearby amenities and health and human services should be consid- ered when reviewing senior housing developments. LU-30 Encourage development of perma- nent supportive housing to address the homeless population and those with spe- cial needs. LU-31 Encourage adaptive reuse, particularly of historic properties. CommerCial l and use designations Character s ketch Commercial uses will be wide ranging in terms of scale and type. A mix of businesses – local, region- al, and national – will be among the businesses in the various designations, and will be carefully located to create balance and maintain appropri- ateness based on adjacent uses. These commer- cial areas will be economically vibrant, unique, and active outside of traditional work hours. They will be accessible by foot, bike, car, and public transport. Values Character – Active gathering spaces, such as parks, plazas, cafes, concert venues, festivals and markets, will be distributed throughout the City; these spaces will be engaging and filled with peo- ple interacting, irrespective of culture, age, or in- come level. Wellness: A variety of healthy food options will be physically and economically accessible to all members of the Auburn community. Service: The City’s resources and services are available and utilized by the business commu- nity. The business community finds the City ap- proachable, empathetic, and responsive. An open and collaborative dialogue exists to help identify problems and find solutions. Economy: A wide complement of retail, service, and dining options will cater to local needs, at- tract visitors, and encourage consistent patron- age of local businesses. Celebration: Auburn will have a thriving and ex- panding arts and culture community. There will be events, amenities, and attractions that draw people to congregate and socialize. Environment: Local businesses benefit from Auburn’s collection of natural resources and amenities because residents and visitors are choosing Auburn as their home or destination. land use element LU-7 Vol. 1Sustainability: Local businesses benefit from, and contribute to, a sustainable economy because Auburn is an easy location to start up, main- tains opportunity for growth, and has a business friendly economic climate. General Policies LU-32 The commercial uses permitted must be carefully regulated in regards to perfor- mance criteria and design. LU-33 Permitted uses would consist of local-serv- ing and community-serving retail trade, offices, personal services, and eating establishments. LU-34 Encourage uses that provide health and human services to the adjacent community. LU-35 Encourage adaptive reuse, particularly of historic properties. LU-36 Promote the use of energy and water con- servation measures (PSRC 11/12/15) LU-37 Ensure that legally established existing uses that may not conform with the under- lying zone, but that are compatible with their surrounding uses, and are allowed to continue to evolve and operate without being classified as “nonconforming” uses. downtown urban Center designation Description This category should be applied exclusively in downtown Auburn. The area should be devel- oped in a manner consistent with and conducive to pedestrian-oriented activities. The ambiance of the downtown should encourage leisure shop- ping, provide services to local residents and area employees, and provide amenities that attract re- gional visitors and shoppers. Designation Criteria 1. Located within the Urban Center boundaries established by the King County Countywide planning policies or within Business Improvement Area boundaries. Implementing Zoning Designations Downtown Urban Center Policies LU-38 Vertical mixed-use should be encouraged; the location of retail sales and services should predominately be on the ground floor with residential or more retail or ser- vices above. However, small freestanding commercial spaces may be established as an accessory use to a larger vertical mixed-use development. LU-39 Deviations of height, density or intensity limitations should be allowed when sup- plemental amenities are incorporated into site and building design. Examples of amenities include use of low-impact development, use of sustainable site and building techniques, public space and art, transit-oriented development, landscap- ing and lighting, and bike shelters - as well as the inclusion of affordable housing. LU-40 Encourage a broad mix of uses within the downtown area. A wide range of consum- er-oriented goods and services are com- patible within this designation since cre- ating an attractive shopping environment is a primary emphasis. Permitted uses include retail trade, offices, personal ser- vices, eating and drinking establishments, financial institutions, governmental offices, and similar uses. Legally established exist- ing uses that do not fit within the range of desired new uses continue to be a valu- able part of the downtown economy and character and should be allowed to evolve and operate in a manner that resembles listed permitted uses. LU-41 Encourage multiple family dwellings, particularly within the upper stories of buildings. LU-42 Drive-in windows should not be permit- ted to maintain the area’s pedestrian environment. LU-43 Parking standards within the downtown should reflect the pedestrian orientation of the area, but also consider parking’s im- pact for economic development. City of Auburn Comprehensive plAn LU-8Vol. 1LU-44 Discourage uses that rely on direct access by vehicles or involve heavy truck traffic (other than for merchandise delivery). LU-45 Unsightly outdoor storage and similar ac- tivities should be prohibited. LU-46 The downtown should capitalize on op- portunities for multimodal transportation. LU-47 Encourage adaptive reuse, particularly of historic properties. LU-48 As a designated VISION 2040 Regional Growth Center that contains a transit station, land use policies and regulations should encourage population and em- ployment growth. neighborhood Commercial designation Description Low-intensity, small-scale commercial servic- es that meet the daily needs of and complement the quality of the residential neighborhoods they serve. Commercial uses need to be carefully lo- cated (if located within single-family residen- tial neighborhoods) or should be buffered from single-family residential areas. These areas are characterized by lower traffic generation, fewer operating hours, smaller-scale buildings, and less signage than light commercial areas. Designation Criteria 1. Located along arterial or collector streets; 2. Properties that are buffered from the sin- gle-family designation by landscaping, en- vironmental features, or the Residential Transition designation; and 3. Meets the development parameters of the Neighborhood Commercial designation. Implementing Zoning Designations Neighborhood Commercial Policies LU-49 The commercial uses permitted must be carefully regulated in regards to perfor- mance criteria and design. Architectural style, building height and size, lighting, and signage should be consistent with the surrounding residential properties. LU-50 Permitted uses would consist of small-scale local-serving and community-serving re- tail trade, offices, personal services, and non-drive-through eating establishments. LU-51 Special emphasis will be directed at those accessory activities that can alter the character of these areas into heavier com- mercial areas. Examples include outdoor storage, location and screening of trash receptacles, loading and unloading zones, and parking lots. Regulations and permit conditions will employ techniques that mit- igate light and noise impacts associated with surrounding residential properties. LU-52 Encourage adaptive reuse of existing res- idential buildings and historic properties. LU-53 Commercial uses will have an orientation that is directed toward adjacent public streets while also providing pedestrian and bike-oriented access. LU-54 Upzone requests to the next zone should be approved based on the innovations in transportation and stormwater man- agement and public amenities proposed for the development associated with the request. light Commercial designation Description This category represents the prime commercial designation for small-to moderate-scale com- mercial activities. These commercial areas should be developed in a manner consistent with and at- tracts pedestrian-oriented activities. Such areas should encourage walkability, leisure shopping, engaging public space, and should provide other amenities conducive to attracting shoppers. Designation Criteria 1. Previously developed light commercial areas buffered from more intense commercial or land use element LU-9 Vol. 1industrial designations by landscaping or en- vironmental features; or 2. Located along arterial or collector streets; 3. Properties that are buffered from the sin- gle-family designation by landscaping, en- vironmental features, or the Residential Transition designation; and 4. Meets the development parameters of the Light Commercial designation. Implementing Zoning Designations Light Commercial Policies LU-55 A wide range of consumer-oriented goods and services are compatible within this designation since creating an attractive shopping environment is a primary em- phasis. Permitted uses would consist of lo- cal-serving and community-serving retail trade, offices, personal services, eating establishments, financial institutions, gov- ernmental offices, and similar uses. LU-56 Parking lots must be located and designed in a manner that softens their appearance from adjacent public roads. This is accom- plished through landscaping, pedestrian spaces, and the location of buildings on the property. Where practicable, low-im- pact development techniques and land- scaping should be used to promote on site stormwater infiltration and shading of hard surfaces. Minimum and maximum parking ratios must be established for each type of permitted use. LU-57 Development incentives should be estab- lished that encourage the creation of elec- tric car charging stations, use of sustain- able building and/or operational practic- es, development of nonmotorized infra- structure, and proximity and connection to public transit. LU-58 Multiple family dwellings are only allowed as part of mixed-use developments where they do not interfere with the shopping character of the area, such as within the upper stories of buildings. LU-59 Drive in windows should only be allowed accessory to a permitted use, and only when carefully sited under the adminis- trative use process, in order to ensure that an area’s pedestrian environment is not compromised. LU-60 Large-scale regional retail uses and uses that rely on direct access by vehicles or involve heavy truck traffic (other than for merchandise delivery) are not appropriate in this category. LU-61 Unsightly outdoor storage and similar ac- tivities should be prohibited. LU-62 Encourage adaptive reuse, particularly of historic properties. LU-63 Upzone requests to the next zone should be approved based on the innovations in transportation and stormwater man- agement and public amenities proposed for the development associated with the request. Heavy Commercial designation Description This category is intended to accommodate uses that would also accommodate a wide range of heavier commercial uses involving extensive stor- age or vehicular movement. Designation Criteria 1. Previously developed heavy commercial areas; or 2. Located along major arterial streets; 3. Properties that are buffered from the sin- gle-family designation by landscaping, en- vironmental features, or the Residential Transition designation and buffered from all other Residential designations; and 4. Meets the development parameters of the Heavy Commercial designation. Implementing Zoning Designations Heavy Commercial: All Heavy Commercial des- ignated land not located within the Northeast Auburn Special Planning Area or located with- in the Northeast Auburn Special Planning Area, City of Auburn Comprehensive plAn LU-10Vol. 1but incapable of meeting the C-MU zoning requirements. Policies LU-69 A wide variety of commercial-oriented services are appropriate within this cat- egory. This includes but is not limited to regional-scale retail and entertainment uses, commercial uses with outdoor sales areas, drive-in restaurant or other drive in commercial businesses, and commer- cial services with outdoor storage as an accessory use. LU-70 Parking lots must be located and de- signed in a manner that softens their appearance from adjacent public roads. This is accomplished through landscap- ing, pedestrian spaces, and the loca- tion of buildings on the property. Where practicable, low-impact development techniques and landscaping should be used to promote on site stormwater in- filtration and shading of hard surfaces. Minimum and maximum parking ratios must be established for each type of permitted use. LU-71 Development incentives should be estab- lished that encourage the creation of elec- tric car charging stations, use of sustain- able building and/or operational practic- es, development of nonmotorized infra- structure, and proximity and connection to public transit. industrial l and use designations Character s ketch Industrial uses will become a more integrated part of the physical and social life of the City. Since so many people work in these areas and these companies contribute so much to the financial life of the city, it is important that they are connected through paths, roads and by public transportation. Locations that have access to rail and highways that also encour- age intelligent growth patterns will be prioritized. Innovation will be a key requirement of new and in- fill projects as the City looks to mitigate impacts of production and limit damage to the environment. Values Character: Buildings, landscaping, and outdoor spaces will be attractive, interesting, well designed, and well maintained. Wellness: Risk to life and property from all hazards will be minimized. Properties and businesses are connected to nonmotorized corridors that offers alternative means to commute. Service: The city works closely with individuals and organizations to fully understand the demands, needs, and concerns of the industrial community so that the City can sponsor initiatives that help aid in their success. Economy: Cornerstone institutions will strategically expand in regional prominence. As industry grows, land use policy will support efforts to grow within Auburn. Celebration: The Community will be made aware of and celebrate the accomplishments of our local, regional and international leaders in manufactur- ing, warehousing, and distribution. Environment: The built environment will fit into the natural landscape in a way that protects and re- spects ecosystem function. Natural resource pro- tection will be supported and celebrated by City leadership and the community. Sustainability: Industrial uses are contributing to, and supportive of, efforts to build and maintain a transportation system that ensures the people and goods move safely throughout the City and beyond. General Policies LU-72 A wide range of industrial uses may be per- mitted, subject to performance standards. LU-73 Outside storage shall be permitted sub- ject to performance criteria addressing its quantity and location. LU-74 Development incentives should be es- tablished that encourage the creation of electric car charging stations, use of sustainable building and/or operational practices, development of nonmotorized land use element LU-11 Vol. 1infrastructure, and proximity and connec- tion to public transit. LU-75 Promote the use of energy and water con- servation measures light Industrial designation Description This category is intended to accommodate a wide range of industrial and commercial uses. This designation is intended to provide an attrac- tive location for manufacturing, processing and assembling land use activities that contribute to quality surroundings. A wide variety of appropri- ate commercial uses in this designation benefit from the location, access, physical configuration, and building types of these properties. It is distin- guished from heavier industrial uses by means of performance criteria. All significant activities shall take place inside buildings, and the processing or storage of hazardous materials shall be strict- ly controlled and permitted only as an incidental part of another use. Designation Criteria 1. Previously developed light industrial areas; or 2. Located along high-visibility corridors; 3. Provides buffering for heavy industrial areas or is buffered from the single-family designa- tion by landscaping, environmental features, or the Residential Transition designation and buffered from all other Residential designa- tions; and 4. Meets the development parameters of the Light Industrial designation. Implementing Zoning Designations Light Industrial Policies LU-76 A wide range of industrial uses may be permitted, subject to performance stan- dards. Heavy commercial uses that serve the needs of workers in light industries are also appropriate. These uses include indoor manufacturing, processing, and assembling of materials from previously prepared or raw materials and ancillary and necessary warehousing and distribution of finished goods associated with manufacturing and industrial uses. LU-77 Parking lots must be located and designed in a manner that softens their appearance from adjacent public roads. This is accom- plished through landscaping, pedestrian spaces, and the location of buildings on the property. Where practicable, low-im- pact development techniques and land- scaping should be used to promote on site stormwater infiltration and shading of hard surfaces. Minimum and maximum parking ratios must be established for each type of permitted use. LU-78 Landscaping, sidewalks, and bike paths will be integral parts of site design if a develop- ment is located on an impression corridor or located within or adjacent to an identified nonmotorized corridor. LU-79 Outside storage shall be permitted subject to performance criteria addressing its quan- tity and location. This is to ensure compat- ibility with adjacent uses, so that such stor- age would not detract from the potential use of the area for light industry. In all cases, such storage shall be extensively screened. LU-80 Where a light industrial use is located adja- cent to a property with a less intense zoning designation, the light industrial use bears the burden of incorporating techniques that mitigate the visual, noise, dust, and odor impacts. LU-81 Uses involving substantial storage or pro- cessing of hazardous materials, as well as substantial emissions, should not be per- mitted in these areas. LU-82 A wide range of commercial activities may be allowed to provide increased opportu- nities for sales tax revenue. LU-83 The Burlington Northern Santa Fe Railroad Auburn Yard located within the Railroad Special Plan Area is considered a compatible use at its current level of usage. It is not bound by the policies concerning outside storage under the existing light industrial designation City of Auburn Comprehensive plAn LU-12Vol. 1as it was an existing use prior to the develop- ment of this policy. Should BNSF decide to re- activate its applications to upgrade the yard to an intermodal facility, the proposal will be subject to the essential public facility siting process as defined in the Capital Facilities Element. LU-84 Upzone requests to the next zone should be approved based on the innovations in transportation and stormwater man- agement and public amenities proposed for the development associated with the request. Heavy Industrial designation Description This designation allows the full range of industri- al uses, as well as certain heavy commercial uses that serve the needs of workers in light industries are also appropriate. Designation Criteria 1. Previously developed heavy industrial areas; or 2. Not located along high-visibility corridors; 3. Buffered by the Light Industrial Designation or otherwise buffered from all other compatible designations; and 4. Meets the development parameters of the Heavy Industrial designation. Implementing Zoning Designations Heavy Industrial Policies LU-85 While this zone should be reserved pri- marily for the heavier forms of industrial activities, a wide range of industrial ac- tivities may be permitted. These heavier forms of industrial activities may include outdoor or semi-enclosed manufacturing, processing, or assembling activities, signif- icant outdoor storage, and uses involving substantial storage or processing of haz- ardous materials. Heavy commercial uses that serve the needs of workers in heavy industries are also appropriate. LU-86 Parking lots must be located and designed in a manner that softens their appearance from adjacent public roads. This is accom- plished through landscaping, pedestrian spaces, and the location of buildings on the property. Where practicable, low-im- pact development techniques and land- scaping should be used to promote on site stormwater infiltration and shading of hard surfaces. Minimum and maximum parking ratios must be established for each type of permitted use. LU-87 Landscaping, sidewalks, and bike paths will be integral parts of site design if a development is located on an impression corridor or located within or adjacent to an identified nonmotorized corridor. LU-88 Where a heavy industrial use is located adjacent to a property with a less intense zoning designation, the heavy industri- al use bears the burden of incorporating techniques that mitigate the visual, noise, dust, and odor impacts. PubliC and institutional l and use designations Character s ketch Public and institutional uses will occur in both low- and high-density environments. For passive uses, land and views will be protected; limited access to these areas will be typical. For more active uses, usability and accessibility will be key features and new development will be subject to standards re- flecting programmed space and interconnectivi- ty. These spaces will be varied in type, providing service to areas large and small, urban and more rural in character. Sustainable solutions and inno- vations that are responsive to the native ecology will be typical of public and institutional uses. Values Character: Community facilities and programs bring people together and connect residents and visitors to our natural resources. land use element LU-13 Vol. 1Wellness: Multiple recreation options, and nearby trails, parks, activities, and events will be readily accessible to the entire community. Service: Land use policy supports the provision of community, health and human services to all residents. Economy: Residents and visitors seek Auburn as a residence or destination because of its natural re- sources, community events, and community pride. Celebration: We utilize our open spaces and pub- lic facilities to promote who we are, our diversity, and our community pride. Environment: Residents and visitors will enjoy open spaces and environmentally sensitive areas, while encouraging the appreciation of their im- portance and beauty. Impacts of new develop- ment on natural resources are considerate of their sensitivity and importance. Sustainability: Public and private funds are used to make investments in land preservation, resto- ration and protection. Public investments in land and facilities are considered for their perpetual or generational value versus short-term motivations. General Policies LU-89 The primary purpose of this designation is to address public needs while taking ad- vantage of synergies with the adjacent areas where they are sited. LU-90 Innovative strategies to integrate the uses and sites into the areas where they are sited is encouraged. These strategies should maximize use of the site while min- imizing fiscal impacts and impacts to ad- jacent areas. LU-91 Increase visibility of resources through public information campaigns. LU-92 Appropriate uses include low-intensi- ty recreational uses, passive use open areas, protected environmental habitat, stormwater detention facilities, and similar low-intensity uses. LU-93 Promote the use of energy and water con- servation measures open space designation Description This category shall be applied to areas that are owned by a public entity and managed in a large- ly undeveloped character. It includes parks, wa- tersheds, shoreline areas, significant wildlife hab- itats, storm drainage ponds, utility corridors with public access, and areas with significant develop- ment restrictions. Designation Criteria 1. Passive parks or undeveloped Parks Department property; 2. Any site containing a significant developmen- tal hazard; or 3. Any site containing open space value suita- ble for public protection without unduly en- croaching on private property rights. Implementing Zoning Designations Open Space Policies LU-94 Active parks that provide sports field, ac- tivity and community centers, cemeteries, and public buildings should not be desig- nated as open space. LU-95 Open space lands are primarily designat- ed to provide wildlife and aquatic habitat, flood detention, vegetation and soil pres- ervation, and view shed protection. Land designated as open space may be used for public access to trails, interpretive centers, education opportunities, and other uses and facilities that support the purpose of their designation. LU-96 Increase distribution of open space and increase access to open space amenities throughout Auburn. LU-97 Enhance restoration, preservation and protection of natural resources and critical areas. City of Auburn Comprehensive plAn LU-14Vol. 1LU-98 Seek out opportunities to develop rec- reation and education opportunities on public lands or through public–private partnerships. LU-99 Increase visibility of resources through public information campaigns. Continue to work with regional partners to devel- op and maintain trail systems that con- nect Auburn with regional destinations. LU-100 Build on partnerships with school dis- tricts to expand public use of school fa- cilities for recreation and exercise, and to improve public access to facilities for this purpose, as appropriate. Public/Quasi-Public designation Description This category includes those areas that are re- served for public or quasi-public uses. It is intend- ed to include those of a significant extent, and not those smaller public uses that are consistent with and may be included in another designation. These public uses include public schools, devel- oped parks, and uses of quasi-public character such as large churches and private schools. Public uses of an industrial character are included in the industrial designation, and small-scale religious institutions of a residential character are includ- ed in the residential designation. Streets, utilities, and other separate uses are not intended to be mapped separately as Public/Quasi-Public. Designation Criteria 1. Previously developed institutional uses; or 2. Meets the development parameters of the Public/Quasi-Public designation. 3. Properties identified in the Airport Master Plan as Landing Field. Implementing Zoning Designations Institutional Public Use Landing Field Policies LU-101 A responsible management entity and the purpose for the public/quasi-public designation should be identified for each property interest within this designation. Management policies and plans are ap- propriate for all lands in this designation. LU-102 Appropriate uses for this designation in- clude facilities that serve the needs of the larger community such as public schools, active parks, city operated municipal fa- cilities, large churches, and fire stations. LU-103 This designation permits a wide array of uses that tend to be located in the midst of other dissimilar uses. For this reason, the following must be considered of new requests for this designation: a. The impacts that the designation may have on the surrounding community. b. Site-specific conditions that should be attached to new requests for this designation that are designed to mitigate impacts on the surrounding community. c. Site-specific conditions that should be attached to development propos- als that are designed to mitigate im- pacts on the surrounding community. LU-104 Coordination with other public or insti- tutional entities is essential in the imple- mentation of this land use designation. LU-105 Industrial and commercial uses that are affiliated with and managed by edu- cational institutions for vocational edu- cational purposes may be classified as an institutional use and permitted on a con¬ditional basis. LU-106 For the Landing Field (LF) zone, an Airport Master Plan (AMP) should be developed that establishes the vision, policies, and implementation strategies that govern uses, management principles, and fu- ture planning efforts. The AMP shall be incorporated by reference in the Auburn Comprehensive Plan as an appendix. land use element LU-15 Vol. 1LU-107 Auburn Municipal Airport is included in the federal airport system - the National Plan of Integrated Airport Systems (NPIAS). Participation in the NPIAS is limited to public use airports that meet specific FAA criteria. NPIAS airports are eligible for federal funding of im- provements through FAA programs. To maintain eligibility for funding through FAA programs, the Airport Master Plan should be periodically updated as con- ditions change. LU-108 Uses, activities, and operations within the LF Airport Landing Field District must be coordinated and consistent with the Airport Master Plan. LU-109 Future expansions of the LF Airport Landing Field District, for the purpose of airport uses, activities, and operations, should be coordinated and consistent with the Airport Master Plan. LU-110 While the industrially designated area east of the Airport is highly suited for airport related activities, other indus- trial type uses are now located here. Therefore, the City will encourage use in this area to take advantage of its prox- imity to the Airport. LU-111 New commercial land uses in proximity to the airport should be air-related and/ or complementary to the airport. LU-112 To protect the viability of the Auburn Municipal Airport the City shall create an airport overlay that is consistent with FAA regulations and WSDOT guidance. LU-113 The City’s zoning ordinance and other appropriate regulatory measures shall enforce the airport overlay and the FAR Part 77 surfaces. LU-114 The airport overlay shall protect the op- erations of the Auburn Municipal Airport by establishing controls on incompatible land uses and development. LU-115 The airport overlay should be imple- mented to manage land uses and de- velopment around the airport to ensure compatibility into the future and prevent incompatible future uses. The regula- tions applied to properties surrounding the airport should encourage land uses that are related to, and benefit from, proximity to the airport but not restricted exclusively to only these. LU-116 The impact of development on air safety shall be assessed through the City zon- ing ordinance, FAA regulations, SEPA review, input from the Auburn Municipal Airport, and relevant technical guidance. Appropriate mitigation measures shall be required by the City. LU-117 Uses in proximity to the airport that may create potential operational (e.g. height or noise) conflicts shall be reviewed for their consistency to airport oper- ations and conformance with the FAA regulations. LU-118 The airport should be protected from nonconforming uses and structures that pose a safety concern to airport operations. LU-119 The City shall determine whether non- conforming uses and structures affect airport operations and require their minimization or elimination, at cost to owner, based on individualized study of proposals, City regulations, input from the Auburn Municipal Airport, and rele- vant technical guidance. oVerlays, u rban g rowth area, and sPeCial Planning l and use designations Character s ketch These areas help control growth, protect the en- vironment, and prevent urban sprawl conditions in our City. For a variety of reasons, specific areas exist within the City that require further specificity or focus of land use planning, policy, regulation, or investment. Overlays, urban growth areas, and special planning areas may be designated that help further enumerate a purpose. These areas are to be designated through the Comprehensive Plan and treated as a component of the Land Use City of Auburn Comprehensive plAn LU-16Vol. 1Element of the Plan. Values Each area designated as an overlay, urban growth area, or special planning area shall reflect the values identified in the Core Comprehensive Plan. General Policies LU-120 These land use designations must be consistent with the Growth Management Act, Puget Sound Regional Council, and countywide planning policies. LU-121 Any proposed changes to these desig- nations must be pursued in coordina- tion with applicable State, Regional and County agencies. u rban separator designation Description Urban separators are areas designated for low-density uses in the King County Countywide planning policies. They are intended to “protect Resource Lands, the Rural Area, and environmen- tally sensitive areas, and create open space and wildlife corridors within and between communi- ties while also providing public health, environ- mental, visual, and recreational benefits.” There are two primary areas of urban separators, one on Lea Hill and one on West Hill. Designation Criteria Areas designated through the process of annexation Implementing Overlay Designations Lea Hill Overlay West Hill Overlay Urban Separator Overlay Policies LU-122 The City is obligated to maintain (and not redesignate) until at least the year 2022, pursuant to countywide planning poli- cies and an annexation agreement with King County. LU-123 Urban separators are deemed to be both a regional as well as local concern and no modifications to development regulations governing their use may be made without King County review and concurrence. Therefore, the areas des- ignated as “urban separator” on the Comprehensive Land Use map, will be zoned for densities not to exceed one dwelling unit per acre, with lot clustering being required if a subdivision of land is proposed. urban Growth area and Potential annexation area designation Description Urban growth areas and potential annexation areas are areas located outside of the municipal city limits of Auburn. They are areas that are an- ticipated to be incorporated into the City within 10 years of their designation. Designation Criteria Potential annexation areas are jointly developed by cities and the County in which they are locat- ed. They are based upon countywide growth pro- jections that are divided among all urban growth areas within each respective County. Urban growth areas and potential annexation areas are distinguished from each other by whether they have been assigned to a City or not. Urban growth areas have been identified but have not been as- signed to a City. Potential annexation areas are urban growth areas that have been assigned to a specific City. Implementing Designations Urban Growth Area Potential Annexation Area Policies LU-124 Work with King and Pierce County, as well as nearby cities, to redesignate urban growth areas into potential an- nexation areas. LU-125 Auburn’s Potential Annexation Area is shown on the Comprehensive Plan Land Use Map (Map 1.1). Map 1.1 also depicts Growth Impact Areas. These Growth land use element LU-17 Vol. 1Impact Areas are generally adjacent cit- ies or unincorporated County lands in which development that occurs poten- tially impacts the city of Auburn. LU-126 The Auburn City Council may revise the boundaries of the Potential Annexation Area in the future, in response to: a. Amendments to King and Pierce County Urban Growth Areas as spec- ified in the King and Pierce County countywide policies b. Discussions between Auburn and adjacent jurisdictions regarding POTENTIAL ANNEXATION AREA boundaries c. Discussions with Pierce County con- cerning the designation of POTENTIAL ANNEXATION AREA boundaries d. Changed circumstances relating to population and employment growth and projections, urban service feasi- bility, or similar factors. LU-127 Develop strategies and agreements for the review of development and provision of utilities within potential annexation areas that have yet to be annexed. LU-128 Prior to annexation, develop strategies and agreements that address the order- ly transition of areas into the City such as transfer of permit authority, infrastruc- ture financing, financing of fire and po- lice services, and interim development regulations. transition designation Description The Transition Designation following establishes policies and guidance are intended to provide a basis for future development of zoning and other regulatory tools to manage and reduce impacts from proximity of boundaries between sharper differences of intensity in land uses and is meant to apply city-wide. Designation Criteria The Designation should apply to areas that are located between single-family and multifamily land use designations; between multifamily and nonresidential land use designations; and be- tween single-family and nonresidential land use designations. Implementing Designations The Designation and implementing zoning and other regulatory tools shall generally apply to the more intense land use designation. Policies LU-129 Between single-family and multifamily: a. Where a multifamily use is pro- posed to be located adjacent to a single-family zone, the multifamily use will bear the burden of provid- ing an adequate transition of land use. Mitigating measures that con- trol light, noise, and dust should be incorporated into multifamily devel- opment proposals. b. Provide non-motorized access through the site in order to connect the adjacent land uses. c. Housing size, type, and orientation shall be utilized as a means of pro- viding harmonious transition of the built environment. d. Provide a mix of townhomes, duplex- es, cottage housing and small-scale multifamily housing. LU-130 Between multifamily and nonresidential a. Where a non-residential use is pro- posed to be located adjacent to a multifamily zone, the non-residential use will bear the burden of providing an adequate transition of land use. Mitigating measures that control light, noise, and dust should be incor- porated into nonresidential develop- ment proposals. b. Provide non-motorized access through the site in order to connect the adjacent land uses. c. Provide a mix of townhomes, duplex- es, cottage housing and small-scale multifamily housing. City of Auburn Comprehensive plAn LU-18Vol. 1LU-131 Between single-family and nonresidential: a. Where a non-residential use is pro- posed to be located adjacent to a single-family zone, the non-residen- tial use will bear the burden of pro- viding an adequate transition of land use. Mitigating measure that control light, noise, and dust should be incor- porated into nonresidential develop- ment proposals. b. Provide non-motorized access through the site in order to connect the adjacent land uses. Critical area o verlay land use Description Under the Growth Management Act cities and counties are required to identify, designate and protect critical areas. Critical areas include (a) wetlands, (b) areas with a critical recharging ef- fect on aquifers used for potable water, (c) fish and wildlife habitat conservation areas, (d) fre- quently flooded areas, and (e) geologically haz- ardous areas. Designation Criteria Designation of critical areas includes both crite- ria that should be applied to the specific type of critical area as well as buffers and/or setbacks that are necessary for the protection of the criti- cal area and/or life and property. Designation of critical areas is based on best available science as it applies to local conditions. Implementing Designations Wetlands Critical Aquifer Recharge Areas Fish and Wildlife Habitat Conservation Areas Frequently Flooded Areas Geologically Hazardous Areas Policies LU-132 Best available science will be utilized for the specific designation criteria and the associated adopted protection stan- dards and development regulations. LU-133 Reasonable use provisions will be in- cluded within the critical area regula- tions that ensure a property owner is not denied use of a preexisting parcel, lot or tract. LU-134 Exemptions to the critical areas ordi- nance should be provided for very lim- ited and justified circumstances such as maintenance of existing land uses, work within some types of human-made fea- tures, limited types of site investigation work, emergency activities, and certain types of invasive vegetation control. LU-135 Critical area regulations will identify the process and standards for alteration of a critical area and criteria related to miti- gation, performance, and monitoring. special Planning area designation Description “Special Planning Areas” consist of Districts, sub- areas, Impression Corridors, and Gateways with- in Auburn that warrant additional empha¬sis in planning, investments, and policy develop¬- ment. Each may be recognized separately with- in the Comprehensive Plan, as an Element of the Comprehensive Plan, or as an subarea plan (dis¬- cussed below). There are a variety of reasons for designating and distinguishing a special planning area, and once designated, a variety of poten¬- tial outcomes. Reasons for designating a special planning area include: • Areas of high visibility and traffic. These areas create an impression or image of Auburn. It is therefore particularly important to ensure that they are attractive and well maintained. Examples include Auburn Way South and as¬sociated major highway on- and off-ramps. • Land use activities that warrant joint planning between the City and owner/operator. In ad¬di- tion to developing approaches and strat¬egies for the land use activity, there may be ad- ditional emphasis on ensuring compatibility with surrounding land uses. Examples include, Green River College, the Auburn Municipal Airport, and Emerald Downs Thoroughbred Horse Racetrack. land use element LU-19 Vol. 1• Neighborhoods in which a resident and mer¬chant live and conduct daily business and leisure. Neighborhoods may also be dis- tin¬guished by physical setting, physical sepa- ra¬tions, and similarity over an area. Examples include downtown, Lea Hill, and Lakeland. • Areas with a focused desire to create great¬er physical and economic cohesiveness. These may be large planned developments or clus¬ters. Examples include the Auburn North Business Area and Mt. Rainier Vista. • Areas with an existing built environment or an existing regulatory framework that does not, in itself, meet the expectations of the seven val¬ues that underscore the Comprehensive Plan. Examples include the need for multimodal connections between West Hill and Lea Hill to north and downtown Auburn. Designation Criteria 1. Districts: The geographic limit of districts and areas that make up this category of Special Planning Areas extends beyond an alignment with any particular street, trail, river, stream, or other linear corridor. Districts may con- tain other smaller Special Planning Areas, such as subareas. Additionally, districts are generally consistent with the geography of one of the eight “neighborhoods”1 identified in the 2014 City of Auburn Community Vision Report. Generally speaking, districts are iden- tified for the purpose of creating identity. This means that the land use designations and overarching policies and implementing regu- lations are not going to change from one dis- trict to the next. Instead, Districts are import- ant for event planning, establishing park and open space level-of-service standards, and promoting community identity. Districts (see Map 1.2) • West Hill • North Auburn • Lea Hill • Downtown • South Auburn 1. The eight “neighborhoods” are identified for comprehensive planning purposes only, as neither the City nor its neighborhoods have elected to officially designate the boundaries of City neighborhoods. • Plateau • Lakeland • Southeast Auburn 2. Subareas: Subareas are smaller in geography than a district. Though relatively large, multi- ple subareas may be located within a single district. Subareas allow for the refinement and recognition of existing unique characteristics within a district. Subareas are intended to an- ticipate, support, and guide long-term growth and redevelopment through planned devel- opment and a unique vision for how that area should look and function in the future. It can also be used to provide flexibility when there is uncertainty regarding how an area may be most appropriately developed in the future. Twenty-eight (28) subareas currently exist. These subareas are categorized into five dif- ferent types of subareas: • Identified Areas; • Designatged Areas; • Economic Development Strategy Areas (a Designated Areas sub-category); • Areas of Concern (another Designated Areas sub-category; and • Adopted Areas. Uses, intensities, and infrastructure develop- ment determined for each subarea or planned area through individual planning processes. Connectivity throughout the planned area, and connections to multimodal transportation oppor- tunities outside of the planned area are also em- phasized through the individual planning process. The result of each individual planning process is the adoption of Comprehensive Plan element or subarea plan for the particular subarea by City Council. Each Plan element must be consistent with the general goals, objectives, and policies of the Comprehensive Plan, and once adopt- ed, subarea plans are intended to guide the fu- ture development of each respectively adopted subarea. City of Auburn Comprehensive plAn LU-20Vol. 12a. Identified Areas: Identified areas are iden- tified as a subarea within the Comprehensive Plan, but have not been established on the Comprehensive Plan Map. Therefore, the specific and detailed boundaries of an identified subarea have not been defined. Identification of a subarea within the Comprehensive Plan occurs by official action of the City Council. Identified Areas • Auburn Golf Course • GSA/Boeing • Green River College • Mary Olsen Farm • Les Gove Campus • Emerald Downs • Auburn High School 2b. Desginated Areas: Designated Areas have been designated on the Comprehensive Plan Map, which defines the specific and detailed boundaries of the area. Designation of an area on the Comprehensive Plan Map occurs by official action of the Auburn City Council. It is intended that future development of these areas will be guided by individual Plan ele- ment or subarea plan of the Comprehensive Plan. The future subarea plan will either sup- plement existing goals, policies, and implement strategies, or replace existing Comprehensive Plan designations and policies for the area within the specific and detailed boundary. Designated Areas (see Map 1.3) • Auburn Municipal Airport • BNSF Rail Yard • Stuck River Road • Lakeview • Mt. Rainier 2b(1). Designated Areas - Areas of Concern: Areas of Concern are a specific type (or sub- category) of designated area. Areas of Concern are established because they represent an area that features a lack in the infrastructure and ser- vices (e.g. municipal water and sewer service, urban roads, traffic demand, and storm water management) necessary to support increase in density or other development. These areas re- quire a close assessment of and an emphasis on infrastructure development and planning to sup- port further development. While this Plan may not fully represent the intensity of uses that could ultimately be supported in these areas (in part due to the current weakness of the City’s infra- structure to support future growth). Development intensification within the Area of Concern needs to be coordinated with the necessary infra- structure and services to support growth. Designated Areas - Areas of Concern (see Map 1.3): • AWS/Auburn Black Diamond Rd. • Pike Street NE • 8th Street NE 2b(2). Designated Areas - Economic Development Strategy Areas: The Economic Development Strategy Areas are a specif- ic type (or subcategory) of designated area. In 2005, City Council adopted six Economic Development Strategy Areas under Resolution No. 3944. These areas, initially identified by a focus group of diverse business and commu- nity interests, are targeted for population and employment growth within the planning hori- zon of the City’s 20-year growth target (2031). By 2012, the City Council added three addi- tional economic development strategy areas , bringing the total to nine (9) strategy areas. During the City’s 2015 update of the Comprehensive Plan the list of economic de- velopment strategy areas to reflect current conditions and status of these areas. As such, two of the original six economic development strategy areas was removed from the list. The Urban Center, one of the original six develop- ment strategy areas, was removed as it is no longer a designated area. The Urban Center, also known as “Downtown Auburn” or the “Downtown Urban Center” is an adopted area (since 2001) and features its own subarea plan. The Auburn Environmental Park (AEP)/Green Zone has also been removed as an econom- ic development strategy area. The AEP/Green Zone economic development strategy area land use element LU-21 Vol. 1was previously zoned EP, Environmental Park Zone. The intent of this zone was to encourage economic development in the form of medi- cal, biotech and “green” technologies includ- ing energy conservation, engineering, water quality and similar uses. Through Ordinance No. 6660 City Council rezoned the AEP/Green Zone from EP, Environmental Park Zone to M-1, Light Industrial, hereby effectively removing the need to designate the AEP/Green Zone as an specific economic development strategy area. The current economic development strate- gy areas are included below. The bounda- ries of the economic development strategy areas are incorporated as designated sub- areas “Designated Areas – Special Planning Areas” map of the Land Use Element. Designated Areas -Economic Development Strategy Areas (see Map 1.3) • A St SE (corridor) • Auburn Way South (AWS) Corridor • Auburn Way North (AWN) Corridor • M St SE (between AWN and AWS) • SE 312th/124th Ave • NW Manufacturing Village • 15th St SW/West Valley Hwy N 2c. Adopted Areas: Adopted Areas include an Adopted Subarea Plan incorporated into the Comprehensive Plan that establishes the purpose of its designation, goals and policies, and implementation strategies. Adoption of a subarea plan occurs by official action of the City Council. As an adopted document of the Comprehensive Plan, the subarea Plans are subject to a review, and if necessary, revision to address changes in conditions, issues, or even characteristics of the planned areas. The review and revision a subarea Plan will also include the review and, if necessary, a revision of zoning regulations and architectural design standards. Adopted Areas (see Map 1.4) • Downtown (Ordinance No. 5549) • Auburn Adventist Academy (Resolution No. 2254) • Auburn North Business Area (Resolution No. 2283) • Lakeland Hills (Resolution No. 1851) • Lakeland Hills South (County H.E. Case Z15/ UP70) • Northeast Auburn (Ordinance No. 6183) 3. Impression Corridors: Impression corridors are aligned with a particular street, trail, river, stream, or specific linear corridor. Some corridors may be part of a subarea, in which case the Impression Corridor policies are additive to a subarea plan. Impression cor- ridors enhance the areas in which residents, businesses, visitors move throughout the City. The benefit of an impression corridor is two- fold: residents know that the City is invested in the aesthetic of main thoroughfares and businesses can build off of the design and aesthetic provided by the impression cor- ridor. Improvements or modification to im- pression corridors consist of aesthetic sig- nage, landscaping, and monument features, and the rehabilitation or removal of existing buildings and property. Impression Corridor boundaries and policies are formally des- ignated by adoption of the Comprehensive Plan. Priority is given to the impression cor- ridors that are a part of a subarea. Priority impression corridors are the thoroughfares in which residents, businesses, visitors move throughout a specific subarea. The priority impression corridors are italicized below. Impression Corridors (see Map 1.5) • Auburn Way North • Auburn Way South • Auburn Black Diamond Road • A Street SE/Auburn Avenue • C Street SW • Division Street • M Street/Harvey Road • Main Street • 8th Street NE • 15th Street SW • West Valley Highway • 15th Street NW/NE • 132nd Ave SE City of Auburn Comprehensive plAn LU-22Vol. 1• SE 320th Street • SE 312th Street • SE 304th Street • R Street • Lake Tapps Pkwy SE • Green River Road • 37th Street NW • S 277th Street • Interurban Trail • Green River • White River • Mill Creek 4. Gateways: Gateways are specific plac- es, intersections, or blocks within the City. These essential locations are established because they constitute the first impression into of Auburn. Gateways are intended to create a “welcome” into distinct areas of the City or into the City itself. They are there- fore highly important to plan, construct, maintain, and enhance their appearance and function. Gateway locations and pol- icies are formally designated by adoption of the Comprehensive Plan. Priority is given to those gateways that are along an prior- ity impression corridor. Priority gateways function as a entrance to an impression corridor. The priority gateways are itali- cized below. Gateways (see Map 1.6) • Auburn Way North and Auburn Avenue (where the roads converge) • East Main Street and M Street NE/ SE (at the intersection) • Auburn Way South and 4th Street SE • Auburn Way S and 6th Street SE • West Main Street between C Street NW and B Street N W • All roads with an entry into the city • Hwy 167 Off Ramps • SR 18 Off Ramps Implementing Designations Planned Unit Development (PUD) Master Plans Policies District Policies. LU-123 Through regulation, capital investment, and community planning, identify, pro- mote and market district identity. Subarea Policies. LU-124 Each subarea will contain its own vision, goals, policies and strategies. LU-125 BNSF Rail Yard - This approximately 150 acre Special Planning Area is located in the south-central portion of the City and surrounded by SR-18 to the North, Ellingson Road to the South, C Street SW to the west and A Street SE to the East. The Special Planning Area should con- sider both sides of C Street and A Street. Consideration should be given to: • The needs of Burlington Northern. • Providing pedestrian, bicycle and vehicular access across the site to connect the southeast and south- west sides of the city. • Providing a more visually appealing “entry corridor” into the City from the south along A and C Streets. • Allowing for a mix of uses including single and multifamily development and commercial and industrial uses where appropriate. LU-126 Stuck River Road - A portion of the Stuck River Road Special Planning Area is cur- rently the site of a large sand and gravel mining operation. This area and other adjacent land comprising a total of ap- proximately 664 acres has been desig- nated as a long term resource area (min- eral resource area), so development of the Special Area Plan for this area should be a low priority as mining is expected to continue on this site for as long as 30 years. The land uses for the Stuck River Road Special Planning Area will be de- termined through the subarea planning process and the City Council’s adop- tion of the subarea plan. Potential land uses applied through the subarea plan- ning process could include single-family land use element LU-23 Vol. 1residential, multi-family residential, commercial, institutional, and recre- ational. Some light industrial uses may be appropriate for consideration and designation through the subarea plan- ning process if the uses are “industrial or business park” in character, conducted entirely within an enclosed building, and exhibit a high degree of performance standards and are non-nuisance in na- ture and if appropriately limited in ex- tent and location. A mix of housing types ranging from single family residential to multi-family residential is appropriate for this planning area. The subarea plan should be adopted taking into consider- ation the period during which mining is expected and the intent of the ultimate development of the area. An active per- mit has been processed by the City with respect to the mining activity on a por- tion (approximately 664 acres) of the mineral extraction operation. The permit process should continue, however, any permit for mining in the mineral resource area should be granted for the life of the resource, with reviews conducted peri- odically (every five years) to determine whether changes in the originally pro- posed mineral extraction operation have arisen and give rise to the need for ad- ditional or revised permit conditions to address the new impacts (if any) of any such changes. Any permit applications for additional acreage within the miner- al resource area shall be processed by the City. Development of this area should not occur until adequate public facilities are available to support the development consistent with City concurrency policy. The City recognizes the potential for ex- panding the Stuck River Road Special Planning Area to include additional land east of Kersey Way and north of the Covington-Chehalis power line ease- ment, and will consider a proposal by all affected property owners. If the area is expanded, the number of non-multiple family, non-manufactured home park dwellings units may be increased pro- portionate to the increase in acreage. Any such proposal shall specifically ap- portion the types and quantities of de- velopment to occur within each sepa- rate ownership. LU-127 Lakeview - The Lakeview subarea is cur- rently the site of two independent sand and gravel mining operations. While mining activity continues in the east- ern operation, indications in 1995 are that the western operation has ceased. Activity in the western portion is now lim- ited to a concrete batch plant and future site reclamation. Following reclamation, the area should be developed as a pri- marily single family residential neigh- borhood of low to moderate urban den- sity. A planned development would be particularly appropriate for this approx- imately 235 acre site. The permitted de- velopment density of the site will depend heavily upon the ability of the transpor- tation system near the site to handle the new uses. Consideration shall be given to the environmental, recreational and amenity value of White Lake, the histor- ical and cultural significance, as well as tribal ownership and jurisdiction of the Muckleshoot Tribe in the development of the Lakeview Plan element. Permit applications have been accepted and are currently being processed by the City with respect to the mining activity on the eastern portion of the area. The permit process should continue, how- ever, any permit for continued mining in this portion of the area should be limited to 10 years to encourage completion of the mining, and subsequent reclama- tion by the property owner in prepara- tion for development. The Lakeview Plan element should be adopted prior to the City’s acceptance or processing of any other permit applications for the min- ing operation in the Lakeview Special Planning Area. The environmental in- formation and analysis included in the Final Environmental Impact Statement for Lakeview (November 1980), shall be considered in the development of the City of Auburn Comprehensive plAn LU-24Vol. 1Lakeview Plan element. While heavy commercial or industrial uses would not be appropriate as permanent uses of this area, conversion of the area now zoned for heavy industry to office commercial (or similar) uses would be appropriate. LU-128 Mt. Rainier Vista - This 145 acre subarea is located south of Coal Creek Springs Watershed. Overall development of the Mt. Rainier Vista subarea plan shall be consistent with the following conditions: 1. Primary consideration in use and development of the property shall be given to protection of Coal Creek Springs’ water quality. Development types, patterns and standards de- termined to pose a substantial risk to the public water source shall not be allowed. 2. The maximum number of dwelling units will be determined as part of any sub-area plan process. Dwelling units shall be located within portions of the property where development poses the least risk of contamination for Coal Creek Springs. Lands upon which any level of development would have a high risk for contaminating the water supply shall not be developed, but would be retained as open space. The development pattern shall provide for a logical transition between areas designated for rural uses and those designated for single family residential use. All dwelling units shall be served by municipal water and sanitary sewer service, and urban roads. If 53rd Street S.E. is the major access to serve the Special Planning Area, the devel- oper will be responsible for developing the street to urban standards, from the property owners’ eastern property line that abuts 53rd Street, west to the in- tersection of 53rd and Kersey Way. 3. Percolation type storm sewer dispos- al systems shall not be permitted. All surface water drainage shall be con- veyed consistent with the City’s current storm drainage standards. Treatment of stormwater shall occur prior to its discharge to any surface water body, consistent with standard public works or other requirements in general effect at the time of development. 4. The site shall be zoned temporari- ly, at one unit per four acres, until the sub-area plan is completed and the long-term urban zoning determined. 5. The Mt. Rainier Vista special plan- ning area boundary may be modi- fied through the development of the subarea plan. 6. The Mt. Rainier Vista and Stuck River Road Special Planning Areas shall be coordinated subarea plans. Designated Areas - Areas of Concern Policies. LU-129 AWS/Auburn Black Diamond Rd – The area between Auburn-Black Diamond Road and the Burlington Northern Railroad currently lacks urban facil- ities necessary to support urban devel- opment. Major development propos- als shall be carefully assessed under SEPA to ensure that the development can be supported by the available fa- cilities. Once property owners are able to demonstrate to the City that they can provide urban services (municipal water and sewer service, urban roads and storm water management) neces- sary to support the intensity of develop- ment proposed within the entire area, the Plan designation and zoning for this area should be changed to an urban residential or commercial classification. The appropriate classification(s) shall be determined after a review of the de- velopment proposal and the pertinent Comprehensive Plan policies. LU-130 Pike Street NE – The area located north of 8th NE, east of Harvey Road, and south of 22nd NE is inadequately served by residential arterials. No increase in density or other development which would increase traffic demand in this area should be approved. LU-131 8th Street NE – The areas paralleling 8th Street NE located between Auburn Way and M Street are designated for multiple land use element LU-25 Vol. 1family residential while 8th Street NE is designated as a minor arterial. However, the road is not currently constructed to this standard and is not able to support current traffic demand adequately. The Plan designation would greatly increase traffic volumes. Implementation of the Plan designations should not occur until 8th Street NE is constructed to the ade- quate arterial standard and water ser- vice is upgraded. Up zones should not be granted from current zoning until these stems are upgraded or guaranteed. Designated Areas - Economic Development Strategy Ares Policies. LU-132 The City should adopt a formal subarea plan for each of the seven economic de- velopment strategy areas (listed below) as an element of the Comprehensive Plan. Each economic development strat- egy area subarea plan should identify the uses, intensities, and infrastructure development necessary to support the types of business and activities that are most consistent with community aspira- tions. Each subarea plan should address and include policies regarding the ex- pected level of housing density (or resi- dential growth targets) and employment growth targets. • Auburn Way South Corridor • Auburn Way North Corridor • NW Auburn Manufacturing Village • 15th St. SW/C St. SW/W Valley Hwy. N • A St. SE • SE 312th St. /124th Ave SE • M St. SE between Auburn Way N and Auburn Way S Adopted Areas Policies. LU-133 Adoption or revision of a subarea plan will be treated as a comprehensive plan amendment and will comply with the Growth Management Act, Countywide planning policies, Vision 2040, and the Core Comprehensive Plan. LU-134 Adventist Academy - Adopted under Resolution No. 2254 on November 14, 1991. The Auburn Adventist Academy is Special Planning Area (Adopted Area) is a multi-use campus operated by the Western Washington Conference of Seventh-Day Adventists. The Campus plays a large role in the Western Washington Conference of Seventh- Day Adventists’ private elementary and secondary education system in Washington and hosts many communi- ty events as well as an annual region- al camp meeting for Adventists from Washington and around the world. The Campus previously housed Harris Pine Mill, a furniture manufacturer, for many years. The Mill provided finan- cial benefit to the Academy’s budget and provided employment opportuni- ties, learning experiences, and voca- tional education for Academy students. The Academy continues to include in its plan industrial uses that support the mission of the school financial- ly. The reuse of existing mill buildings and redevelopment of buildings lost to a fire in 1989 are the focal points of the current industrial development. In addition to institutional and industrial uses, the Academy is also operates a landing strip and associated aircraft hangars for student aviation and flight training. A single family subdivision is located to the south of the airstrip. In addition to these uses, the Academy wishes to allow development of uses such a multi-family and senior housing and assisted living and memory care which will generate perpetual revenue through a long-term land lease on a portion of the Campus lying generally north of Auburn Way South and south of 32nd Street S.E. that will direct- ly aid its mission. The financial bene- fit from these uses will allow funding an endowment, subsidize student tui- tion, provide financial aid for students needing tuition assistance, for new educational programs, for additional faculty, facility maintenance and up- grades, and other needs. The plan focuses on provides predictability to planning, zoning, subdivision, and de- velopment decisions within the Special City of Auburn Comprehensive plAn LU-26Vol. 1Planning Area (Adopted Area) made by the City. LU-135 Auburn North Business Area - Adopted under Resolution No. 2283 on March 2, 1992. The Auburn North Business Area Special Planning Area Plan was the result of a comprehensive planning study due to increased development pressure north of the Central Business District. Since the Central Business District, which contains Downtown, the core of Auburn, is adjacent to these areas, future development in this area is crucial. A comprehensive and cohe- sive direction was also needed based on increased development proposals and rezone requests. In addition to de- velopment concerns, many of the con- siderable undeveloped parcels contain wetlands. All of these factors made de- velopment controls beyond zoning and development regulations advisable. LU-136 Lakeland Hills - Adopted under Resolution No. 1851 on April 18, 1988. Lakeland Hills area lies between the Stuck River and the southern City lim- its of Auburn in the most southwestern part of the City. The area consists of planned residential and commercial subdivisions, and is predominate- ly residential in nature, offering a range of housing types, including sin- gle family and multi-family dwellings. The Lakeland Hills Plan was intended to provide long-term predictability to both the City and potential developers. As a planned community, development and design must be consistent with the policy guidance of the Lakeland Hills Plan. LU-137 Lakeland Hills South - Approved under Pierce County Hearing Examiner Case Z15/UP70.Lakeland Hills South lies south of the Lakeland Hills special plan area and is the most southwestern part of the City. The area is predominate- ly residential, allowing for a range of housing types, with commercial uses, including Lakeland Town Center, in the center. Nonresidential uses, including civic, religious, and municipal ser- vices are allowed throughout the area through an Administrative Use Permit. Unlike Lakeland Hills, Lakeland Hills South was accepted into Auburn was a Planned Unit Development (PUD). The Lakeland Hills PUD, original- ly the Lakeland Hills South Planned Development District (PDD), was ap- proved under Pierce County Hearing Examiner Case no Z15-UP70 in 1990. Lakeland Hills South PUD is intended to provide enhanced flexibility to develop a site through innovative and alterna- tive development standards. As a PUD, specific development and design stan- dards are prescribed. LU-138 Auburn Downtown Plan (Urban Center) - Adopted under Ordinance No. 5549 on May 21, 2001. Downtown Auburn is the business, governmental, and cultural hub of Auburn, its phys- ical and cultural heart. Many stores, restaurants, service providers, and small offices are well-represented throughout this district. Downtown hosts many community events and activities, such as the weekly Auburn International Farmers Market in the summer, Soundbites! Concert Series (in the City Hall Plaza) and the Veterans Day Parade. Downtown features pub- lic art that includes temporary in- stallations such as Pianos on Parade and a permanent outdoor Downtown Sculpture Gallery with rotating pieces. This dynamism is possible because the district is a collection of uses that co- exist in close proximity to one anoth- er. Due to the value, importance, and complexity of this district, The Auburn Downtown Plan identified four gener- al needs to be addressed by the plan: • Update of the existing plan in order to continue Downtown revitalization • Concern over the reopening of Stampede Pass • Multiple large projects proposed for Downtown land use element LU-27 Vol. 1• Scarce private investment In conjunction with project-based items, a regulatory element that emerged from the goals of the Auburn Downtown Plan was the Downtown Urban Center (DUC) zoning district, which was established in 2007. While the DUC zoning district is intended specifically to address the needs of downtown, though the implemen- tation of policies identified by the Downtown Auburn Plan , many chal- lenges related to public and private investment, development, and strate- gic planning have yet to be addressed as downtown has evolved. LU-139 Northeast Auburn Special Plan Area – Adopted under Ordinance No. 6183 on June 5, 2008. The Plan was prepared in fulfillment of the policies includ- ed in the Comprehensive Plan for the area between Auburn Way North and the Green River, south of 277th Street (52nd Street NE) and north of approx- imately 37th Street NE in the City of Auburn (Map No. 14.2). The planning area was narrowed to an area cover- ing approximately 120 acres, north of 45th Street NW and between Auburn Way North and the existing I Street NE right-of-way. The Northeast Auburn/ Robertson Properties Special Area Plan focuses on proposed develop of the Auburn Gateway project area, a 60-acre group of properties owned or under consideration for purchase by Robertson Properties Group, owners of the Valley 6 Drive-In Theater. The plan calls for a mix of office, retail, and multifamily development under a new zoning designation (C-4, Mixed Use Commercial) for the central portion of this planning area, created to accom- modate mixed use development. The plan calls for phased development in coordination with the provision of new roads, stormwater and other utilities, and flood management measures. Impression Corridor Policies. LU-140 Create specific plans for each iden- tified corridor, outlining development policies and regulations, necessary capital improvements, and imple- mentation strategies. In the absence of any specific corridor plans, this section contains general policies that are to be applied within designated impression corridors. LU-141 Coordinate corridor planning, de- sign, construction, and maintenance with other agencies, such as BNSF, the Muckleshoot Indian Reservation, and the Washington State Department of Transportation. Where one agen- cy may more effectively manage the corridor, management or ownership consolidation is appropriate. LU-142 Promote the elimination or renova- tion of existing derelict or unmain- tained structures, signs, fences, and properties along impression corridors through regulatory or enforcement mechanisms LU-143 Work with private and public property owners to educate, create incentives, and enforce regulations that are in- tended to improve the overall ap- pearance of identified corridors. LU-144 Emphasize the design, orientation, construction materials, landscaping, and site layout for development pro- posals of new and existing buildings along impression corridors. New con- struction and the renovation of exist- ing buildings create important oppor- tunities for enhancing the appearance of impression corridors. LU-145 Establish regulations that ensure co- ordinated, attractive commercial signage is of an appropriate size and quantity. Signage regulations along these corridors may be different than those in other areas. LU-146 Take advantage of opportunities to provide informational signs, wayfind- ing signs, and traffic control signs that land use element LU-28 Vol. 1are attractive, useful, and integrated into a larger citywide signage plan or policy. LU-147 Outdoor storage of materials, invento- ry, and other goods and off-street sur- face parking should be located at the rear of the property. If outdoor storage cannot be located in the rear of the property, then it should be screened from view from adjacent rights-of-way. LU-148 Design, construct, and enhance im- pression corridors to accommodate multimodal uses. LU-149 Design and construct vehicular access points in a manner that consolidates access points serving multiple uses. LU-150 Signage, landscaping, and monument features should be used to establish prominent access points. LU-151 Discourage aerial utilities. LU-152 Invest in impression corridors by ac- quiring rights-of-way, constructing and widening sidewalks, installing landscaping, building center medi- ans, constructing parklets, providing street furniture, and constructing other improvements. Gateway Policies. LU-153 Prioritize by rank all gateways and de- velop potential opportunities and de- signs for each location. LU-154 Develop land use regulations that in- corporate gateway priorities and con- cepts into private development pro- posals that are located at identified gateways. LU-155 Coordinate with the Washington State Department of Transportation to un- derstand options and implement ac- tions at gateway location. Many of the gateway locations are within the WSDOT right-of-way. LU-156 Develop design layouts for gateway lo- cations. Designs will identify key areas that greet residents and visitors as they enter the City or downtown center, op- portunities for signage and monument features, and landscaping. LU-157 Maintain established gateways.

APPENDICES SEPTEMBER 2024 / DRAFT / CAROLLO CITY OF AUBURN 2024 COMPREHENSIVE SEWER PLAN APPENDIX D SEPA CHECKLIST SEPA Environmental checklist September 2023 Page 1 (WAC 197-11-960) SEPA1 Environmental Checklist Purpose of checklist Governmental agencies use this checklist to help determine whether the environmental impacts of your proposal are significant. This information is also helpful to determine if available avoidance, minimization, or compensatory mitigation measures will address the prob able significant impacts or if an environmental impact statement will be prepared to further analyze the proposal. Instructions for applicants This environmental checklist asks you to describe some basic information about your proposal. Please answer each question accurately and carefully, to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use “not applicable” or “does not apply” only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decision-making process. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Instructions for lead agencies Please adjust the format of this template as needed. Additional information may be necessary to evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made, the lead agency is responsible for the completeness and accuracy of the checklist and other supporting documents. Use of checklist for nonproject proposals For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable parts of sections A and B, plus the Supplemental Sheet for Nonproject Actions (Part D). Please completely answer all questions that apply and note that the words "project," "applicant," and "property or site" should be read as "proposal," "proponent," and "affected geographic area," respectively. The lead agency may exclude (for non - projects) questions in “Part B: Environmental Elements” that do not contribute meaningfully to the analysis of the proposal. 1 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/Checklist-guidance SEPA Environmental checklist September 2023 Page 2 (WAC 197-11-960) A.

Address and phone number of applicant and contact person: City of Auburn Public Works Department 25 West Main Street Auburn, WA 98001 253-931-3010 Robert Elwell, Sewer Utility Engineer 253-931-4008 4. Date checklist prepared: June 17, 2024 5. Agency requesting checklist: City of Auburn 6. Proposed timing of schedule (including phasing, if applicable): The Comprehensive Sewer Plan is scheduled for adoption during 2024. It identifies near-term projects for the next six years, and long-term projects over the next twenty years. It also provides direction for inspection, maintenance, and operation of the utility. A public hearing was held regarding the adoption of the Plan at the June 4, 2024 Planning Commission meeting. 7. Do you have any plans for future additions, expansion, or further activity related to or connected with this proposal? If yes, explain. SEPA Environmental checklist September 2023 Page 3 (WAC 197-11-960) None beyond those discussed in this Comprehensive Sewer Plan The next comprehensive sewer plan update is proposed for the year 2032. 8. List any environmental information you know about that has been prepared, or will be prepared, directly related to this proposal. Depending upon the scope of projects proposed in the plan, an individual environmental checklist and threshold determination would be completed as specified projects are proposed for construction. There are no environmental or background studies that have been completed for this sanitary sewer plan. 9. Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes, explain. At this time, there are no known pending applications for general applicability related to the area covered by the sewer system. There may be applications pending related to improvements to the sewer system such as various on-going plats and developer extensions occurring within the sewer service area. The City plans to adopt the capital improvement plan outlined in this document as part of the City’s six- year capital facilities plan. 10. List any government approvals or permits that will be needed for your proposal, if known. The Comprehensive Sewer Plan must be approved by the City of Auburn City Council, the King County Council, and the Washington State Department of Ecology. 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat th ose answers on this page. The proposed non-project action includes adoption of the Comprehensive Sewer Plan as an element of the City’s Comprehensive Plan. The City of Auburn’s 2024 Comprehensive Sewer Plan replaces the City of Auburn’s 2016 Comprehensive Sewer Plan. The plan examines the existing sewer service area which includes both areas within the city limits and potential annexation areas for the City of Auburn. It addresses policies, design criteria, and recommends improvements to the sewer system and its service area. The plan analyzes the current level of service and identifies important projects necessary to meet City and State Standards regarding public health, facility efficiency, and operations and maintenance. The wide range of facility improvements includes repair and replacement, system improvements, facility evaluations, and extensions of the utility to meet future sewer demands. The Comprehensive Sewer Plan is an ongoing element of the city Comprehensive Plan and serves as a guide for the operation, maintenance and expansion of the utility within its Sewer Service Area, in accordance with local, County, and State requirements. SEPA Environmental checklist September 2023 Page 4 (WAC 197-11-960) 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans requi red by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The sewer service planning area as established in the plan is defined as the City of Auburn’s existing city limits and potential annexation areas. The City of Auburn’s service area has been modified by several interlocal agreements with neighboring sewer service providers. Those agreements are included in Appendix A of the Comprehensive Sewer Plan. The service area is shown on Figure 1.2 of the Comprehensive Sewer Plan and reflects those agreements. B. Environmental Elements 1. Earth Find help answering earth questions3 a. General description of the site: The sewer service area is characterized by a relatively flat valley floor bordered by steep hillsides and upland plateaus overlooking the valley. Circle or highlight one: Flat, rolling, hilly, steep slopes, mountainous, other: b. What is the steepest slope on the site (approximate percent slope)? The actual land slopes vary throughout the planning area. Steep slopes exist east and north of the Green River on Lea Hill, south of the White River, and west along the West Valley Highway toward the West Hill. The steepest slopes are close to 100 percent. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them, and note any agricultural land of long-term commercial significance and whether the proposal results in removing any of these soils. The valley floor is made up primarily of soils of the Oridia, Renton, Snohomish, and Briscott series. These soils are poorly drained and formed in the alluvium (river 3 https://ecology.wa.gov/regulations-permits/sepa/environmental-review/sepa-guidance/sepa-checklist- guidance/sepa-checklist-section-b-environmental-elements/environmental-elements-earth SEPA Environmental checklist September 2023 Page 5 (WAC 197-11-960) sediments) associated with the White and Green rivers. These are considered good agricultural soils, though in many areas, are not well-drained. There is no designated farmland within the City of Auburn. The hillsides and plateaus are made up of primarily Alderwood associated soils and a small amount of Everett associated soils (U.S. Department of Agriculture, 1973). Alderwood soils are moderately well drained gravelly sandy loams 20-40 inches deep. Beneath these soils is glacial till with low permeability. Roots penetrate easily to the hardpan layer. Runoff potential is slow to medium. Erosion and slippage hazard is moderate, ranging to severe on steeper slopes. The Everett series consists of somewhat excessively drained soils that are underlain by very gravelly sand. These soils formed in very gravelly glacial outwash deposits under conifers. They are found on terraces and terrace fronts and are gently undulating to moderately steep. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. Some steep slopes, in the areas described earlier, are possible locations of unstable soils. Geologic hazard areas including volcanic, seismic, landslide, and erosion hazard areas are mapped in the City Comprehensive Plan and sensitive areas maps. e. Describe the purpose, type, total area, and approximate quantities and total affected area of any filling, excavation, and grading proposed. Indicate source of fill. Does not apply, since the proposed Comprehensive Sewer Plan is a non-project action. Sewer system construction projects identified in the plan will require excavation and grading of an undetermined quantity of material. Specific projects will be subject to individual environmental review prior to construction. f. Could erosion occur because of clearing, construction, or use? If so, generally describe. Does not apply to this non-project action. Specific projects will be subject to individual environmental review before implementation. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? Does not apply, since this non-project action does not involve site specific development proposals. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any. This is a non-project action, so no site specific erosion control is proposed. Specific projects described by the plan will be subject to individual environmental review SEPA Environmental checklist September 2023 Page 6 (WAC 197-11-960) before implementation. Where applicable, erosion and sedimentation control measures together with best management practices per the 2019 Surface Water Management Manual will be used in all areas of potential erosion. 2. Air Find help answering air questions4 a. What types of emissions to the air would result from the proposal during construction, operation, and maintenance when the project is completed? If any, generally describe and give approximate quantities if known. Does not apply to this non-project action. Specific projects, which are subject to environmental review, will be evaluated for their potential impact and corresponding mitigation measures prior to implementation. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. Does not apply to this non-project action. Specific projects, which are subject to environmental review, will be evaluated for their potential impact and corresponding mitigation measures prior to implementation. c. Proposed measures to reduce or control emissions or other impacts to air, if any: Does not apply to this non-project action. Specific projects will be subject to individual environmental review before implementation. However, standard emission controls for construction equipment will be utilized during construction of projects recommended by this plan. 3. Water Find help answering water questions5 a. Surface: Find help answering surface water questions6 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. 4 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/SEPA-checklist- guidance/SEPA-Checklist-Section-B-Environmental-elements/Environmental-elements-Air 5 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/SEPA-checklist- guidance/SEPA-Checklist-Section-B-Environmental-elements/Environmental-elements-3-Water 6 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/SEPA-checklist- guidance/SEPA-Checklist-Section-B-Environmental-elements/Environmental-elements-3-Water/Environmental- elements-Surface-water SEPA Environmental checklist September 2023 Page 7 (WAC 197-11-960) The major bodies of water within Auburn are the Green River, the White River, Mill Creek, Bowman Creek, and White Lake. 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. Does not apply to this non-project action. Specific projects described by the plan will be subject to individual environmental review before implementation and compliance with the City’s Shoreline Master Program. 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. Does not apply to this non-project action. Specific projects described by the plan will be subject to individual environmental review before implementation. 4. Will the proposal require surface water withdrawals or diversions? Give a general description, purpose, and approximate quantities if known. Does not apply to this non-project action. Specific projects described by the plan will be subject to individual environmental review before implementation. 5. Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. Several areas within Auburn lie within the 100-year floodplain of the Green or White River and Mill Creek. . Specific projects described by the plan which lie within these flood plains will be subject to individual environmental review before implementation and must comply with all applicable regulations. 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 b. Ground: Find help answering ground water questions7 1. Will groundwater be withdrawn from a well for drinking water or other purposes? If so, give a general description of the well, proposed uses and approximate 7 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/SEPA-checklist- guidance/SEPA-Checklist-Section-B-Environmental-elements/Environmental-elements-3-Water/Environmental- elements-Groundwater SEPA Environmental checklist September 2023 Page 8 (WAC 197-11-960) quantities withdrawn from the well. Will water be discharged to groundwater? Give a general description, purpose, and approximate quantities if known. Does not apply to this non-project action. Specific projects described by the plan will be subject to individual environmental review before implementation. 2. Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (domestic sewage; industrial, containing the following chemicals…; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. Does not apply to this non-project action. No waste material will be discharged into the ground as a result of this Plan. c. Water Runoff (including stormwater): 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. Does not apply to this non-project action. Specific projects described by the plan will be subject to individual environmental review before implementation. 2. Could waste materials enter ground or surface waters? If so, generally describe. Does not apply to this non-project action. Specific projects described by the plan will be subject to individual environmental review before implementation. 3. Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe. Does not apply to this non-project action.

It is not anticipated that the proposed projects will have a significant impact upon environmentally sensitive areas or areas designated for governmental protection. Improvements to the system described by the plan are intended to increase reliability, thereby reducing the risk of impacts to sensitive areas.. • Proposed measures to protect such resources or to avoid or reduce impacts are: The Plan does not increase the ability of any person, company, or agency to develop projects that would affect sensitive areas. Proposed projects identified as part of the plan will be reviewed on an individual basis and addressed by the appropriate agencies prior to implementation. Conformance with the applicable local, state, and federal guidelines and regulations will be required. 5. How would the proposal be likely to affect land and shoreline use, including whether it would allow or encourage land or shoreline uses incompatible with existing plans ? The Comprehensive Sewer Plan does not allow or encourage uses incompatible with existing plans. Specific projects will be subject to individual environmental review before implementation. • Proposed measures to avoid or reduce shoreline and land use impacts are: None specifically, as this is a non-project action. However, specific projects described by the plan will reviewed for their potential impact to shoreline use and land use as part of individual environmental reviews prior to implementation. 6. How would the proposal be likely to increase demands on transportation or public services and utilities? The proposal will not result in an increase in demands on transportation and public services. The Comprehensive Sewer Plan responds to growth by identifying the public facilities and improvement needed to address future growth addressed by the City Comprehensive Plan. • Proposed measures to reduce or respond to such demand(s) are: The Comprehensive Sewer Plan identifies sewer facilities required to accommodate growth. Any proposal to construct those facilities will be subject to environmental review which will identify specific impacts to transportation, public services or other utilities. 7. Identify, if possible, whether the proposal may conflict with local, state, or federal laws or requirements for the protection of the environment. SEPA Environmental checklist September 2023 Page 23 (WAC 197-11-960) The Sewer Comprehensive Plan does not appear to present any conflict with local, state, or federal laws or requirements.
