PO Box 1790 Snohomish, WA 98291 Department of Community and Economic Development Alex Pietsch, Administrator RE: Sensitive Area Mitigation Monitoring Reports for Petro Vista AKA Woodberry Lane Plat- King County Financial Activity Number A04BN493 -LOSG1088 and City of Renton File No. LUA08-127 Dear Mr. Best: This is a reminder that the Sensitive Area Mitigation financial guarantee associated with King County permit LOSG1088 requires a minimum of 5 years of successful monitoring. This property was annexed into the City limits in March of 2008, so future monitoring reports should be submitted to the City of Renton. The County has also transferred K Best's $20,398 financial guarantee to the City. King County records show that the annual monitoring report for 2006 was not received. No records of this or any subsequent reports were sent to the City. These annual reports are crucial information to track and ensure that your mitigation monitoring project remains in compliance and continues to progress toward final release. If you have prepared and submitted any reports, we did not receive them. Please submit two copies any annual reports already prepared to Rocale Timmons in our Planning Section at the mailing address listed above within the next 30 days. If no reports have yet been prepared, please prepare and submit the first annual report to Rocale within 60 days. We encourage you to be thorough in presenting the current site conditions as it relates to the permit conditions and standards of success (Le., percent survival, cover of planted plants, invasive species percent cover, maintenance, site description, etc.).

Purpose and Initiation Pre-hearing conferences promote efficient case management by providing an informal process for early identification of issues and resolution of procedural malters in complex cases. Evidence generally will not be received at a pre-hearing conference, except when required in order for the examiner to rule on a motion. (Pre-marking and introduction of exhibits to which there is no objection may occur at the discretion of the examiner.) The examiner, on motion of any party or upon hisfher own motion, may convene a pre-hearing conference to: I. Identify, clarify, limit or simplify issues. 2. Hear and consider pre-hearing motions. 3. Schedule hearings, identify parties and witnesses, determine the order of and limits upon testimony, obtain stipulations as to facts and law, identify and admit exhibits, order discovery, and consider and act upon any other matter which may aid in the efficient disposition ofthe hearing. B. Requests for Conference A motion to convene a pre-hearing conference sha11 be made to the examiner as soon as the need for a conference is recognized by the moving party (at least 21 days prior to the scheduled hearing date), and shall state the reasons for the request, including any motions to be presented. For good cause stated in the motion, the examiner may consider a request that fails to meet the 21-day requirement. For hearings authorized under KCC 20.24.080, a motion by any party for a pre-hearing conference shall be granted if timely. However, unless consented to by all parties or otherwise ordered for good cause by the examiner, no pre-hearing conference on an appeal can be convened later than 45 days after receipt of the statement of appeal by the hearing examiner's office. C. Proceedings at Conference A party who has received timely notice of a pre-hearing conference shall identify at the conference any pre-hearing motions not previously made which helshe intends to make. Parties or interested persons may also file timely written pre-hearing motions for consideration at the pre- hearing conference. Failure to make or disclose a motion which was available to the party at the time of the conference may be grounds for its denial if subsequently made. D. Pre-hearing Order Following a pre-hearing conference, the examiner shall issue an order specifying all items determined at the conference. The order shall be binding upon all parties and interested persons who received timely notice of the conference. Revised March 31, 1995 DIRECTIOI\I::; TO DOES HEARING ROOM '- 900 OAKESDALE AVE SW.

Except as modified herein, the facts set forth in the King County Land Use Services Division's preliminary report to the King County Hearing Examiner for the April 27, 2004 public hearing are found to be correct and are incorporated herein by reference. The LUSD staff recommends approval of the application, subject to conditions. The SEPA MDNS condition as described within the staff report should be corrected so that the word "derbies" reads "debris". L02POOI2-Petro Vista 3 3. Dale VanDerschelden has filed a preliminary plat application to subdivide 3.83 acres into 23 lots for single-family residential development. Many of the small R-6 zoned lots will be constructed with attached residential structures. The property is within a rapidly urbanizing area located south ofPetrovitsky Road about 1 mile east of its intersection with the Benson Highway. 4. The major complications with respect to this plat application relate to wetland issues. The tract B onsite wetland functions as a closed depression and overflows Petrovitsky Road to its north during major storm events. As a consequence, most site drainage will be rerouted to a detention tract located directly to the wetland's east, with the wetland itself only receiving a reduced flow sufficient to maintain its hydrology. Since the wetland will no longer be allowed to overflow, existing problems relating to drainage backup on properties to the south should also be resolved. 5. An offsite wetland to the east and its outlet stream have been identified by DOES staff as part of the Soos Creek headwaters system and assigned a class I wetland rating and a class 2 S stream category respectively. Accordingly, the eastern flank of the Petro Vista plat will be constrained by sensitive areas buffers. Moreover, DOES has determined that the offsite stream is in hydraulic continuity with a downstream bog, and the plat will be required to provide enhanced water quality treatment of site runoff. 6. Students from Petro Vista will talk to Renton School District schools, including Benson Elementary located at 116'h Avenue Southeast and Southeast 186'h Street. There are no shoulders or sidewalks along 118,h Avenue Southeast south of the plat, but the roadway only carries a moderate amount of traffic. An alternative route further west via Petrovitsky Road and 116'h A venue Southeast provides better walking facilities but is characterized by more traffic. In view of the small size of the plat in the context of an area-wide lack of walking facilities, it is not appropriate to require the Applicant to cure this neighborhood deficiency. CONCLUSIONS: 1. If approved subject to the conditions imposed below, the proposed subdivision makes appropriate provision for the public health, safety and welfare; serves the public use and interest; and meets the requirements ofRCW 58.17.110. 2. The conditions of approval imposed herein, including dedications and easements, will provide improvements that promote legitimate public purposes, are necessary to serve the subdivision and are proportional to its impacts; are required to make the proposed plat reasonably compatible with the environment; and will carry out applicable state laws and regulations and the laws, policies and objectives of King County. DECISION: The preliminary plat application for Petro Vista, as revised and received on February 26, 2004, is APPROVED, subject to the following conditions of final plat approval: I. Compliance with all platting provisions of Title 19 of the King County Code. 2. All persons having an ownership interest in the subject property shall sign on the face of the final plat a dedication that includes the language set forth in King County Council Motion No. 5952. L02POOI2-Petro Vista 4 3. The plat shall comply with the base density (and minimum density) requirements of the R-6-S0 zone classification. All lots shall meet the minimum dimensional requirements of the R-6 zone classification or shall be as shown on the face of the approved preliminary plat, whichever is larger, except that minor revisions to the plat which do not result in substantial changes may be approved at the discretion of the Department of Development and Environmental Services. 4. All construction and upgrading of public and private roads shall be done in accordance with the King County Road Standards established and adopted by Ordinance No. 11187, as amended (1993 KCRS). 5. The Applicant must obtain the approval ofthe King County Fire Protection Engineer certifYing the adequacy of the fire hydrant, water main, and fire flow to meet the standards of Chapter 17.08 of the King County Code. 6. Final plat approval shall require full compliance with the drainage provisions set forth in King County Code 9.04. Compliance may result in reducing the number andlor location oflots as shown on the preliminary approved plat. Preliminary review has identified the following conditions of approval which represent portions of the drainage requirements. All other applicable requirements in KCC 9.04 and the Surface Water Design Manual (SWDM) must also be satisfied during engineering and final review. a. Drainage plans and analysis shall comply with the 1998 King County Surface Water Design Manual and applicable updates adopted by King County. DDES approval of the drainage and roadway plans is required prior to any construction. b. Current standard plan notes and ESC notes, as established by DDES Engineering Review, shall be shown on the engineering plans. c. The following note shall be shown on the final recorded plat: All building downspouts, footing drains, and drains from all impervious surfaces such as patios and driveways shall be connected to the permanent storm drain outlet as shown on the approved construction drawings # on file with DDES andlor the King County Department of Transportation. This plan shall be submitted with the application of any building permit. All connections of the drains must be constructed and approved prior to the final building inspection approval. For those lots that are designated for individual lot infiltration systems, the systems shall be constructed at the time of the building permit and shall comply with plans on file." d. Storm water facilities shall be designed using the KCRTS Level One Flow Control standard. Water quality facilities shall also be provided using the Sphagnum bog protection menu. As shown on the conceptual drainage plan, the outlet of the detention pond and water quality facility will connect to the existing conveyance system along Petrovitsky Road and small areas of undetained flows will be used to maintain wetland hydrology within Tract B. Based upon the final drainage analysis, the size of the proposed drainage tracts may have to increase to accommodate the required detention storage volumes and water quality facilities. All runoff control facilities shall be located in a separate tract and dedicated to King County, unless portions of the drainage tract are used for recreation space in accordance with KCC 21A.14.180. L02POOI2-Petro Vista 5 e. The final drainage analysis shall evaluate the requirements for off-site bypass as outlined in the drainage manual on page 1-36. As noted in the design criteria, the contribution of flows to an onsite wetland must be maintained and the natural attenuation of flows under pre-developed conditions must also remain. The design engineer shall evaluate all areas which may contribute offsite flows including the ditch along 118 1h Avenue SE. As noted in the applicants Level One Offsite analysis dated May 15,2003, during major stonn events the onsite wetland fills up and overtops to Petrovitsky Road and also backs up water across the south property line. The design engineer shall evaluate any potential flooding issues and provide drainage designs which adequately prevent potential drainage problems. As shown on the preliminary plat, an interceptor swale is proposed along the south property line oflots 10 and II. f. The final drainage plans and technical reports shall evaluate all applicable design criteria for onsite closed depressions and ponding areas as discussed in the drainage manual on page 3-54. The existing wetland in Tract B currently captures surface water from offsite areas and the western portion of the project area which may influence the stonn water modeling for pre-and post-developed flow rates and volumes.

Except as modified herein, the facts set forth in the King County Land Use Services Division's preliminary report to the King County Hearing Examiner for the April 27, 2004 publ ic hearing are found to be correct and are incorporated herein by reference. The LUSD staff recommends approval of the application, subject to conditions. The SEP A MDNS condition as described within the staff report should be corrected so that the word "derbies" reads "debris". L03P0007-Biller Subdivision 3 3. Dale VanDerschelden has filed a preliminary plat application to subdivide 3.83 acres into 23 lots for single-family residential development. Many of the small R-6 zoned lots will be constructed with attached residential structures. The property is within a rapidly urbanizing area located south ofPetrovitsky Road about 1 mile east of its intersection with the Benson Highway. 4. The major complications with respect to this plat application relate to wetland issues. The tract B onsite wetland functions as a closed depression and overflows Petrovitsky Road to its north during major storm events. As a consequence, most site drainage will be rerouted to a detention tract located directly to the wetland's east, with the wetland itself only receiving a reduced flow sufficient to maintain its hydrology. Since the wetland will no longer be allowed to overflow, existing problems relating to drainage backup on properties to the south should also be resolved. 5. An off site wetland to the east and its outlet stream have been identified by DDES staff as part of the Soos Creek headwaters system and assigned a class I wetland rating and a class 2 S stream category respectively. Accordingly, the eastern flank of the Petro Vista plat will be constrained by sensitive areas buffers. Moreover, DDES has determined that the offsite stream is in hydraulic continuity with a downstream bog, and the plat will be required to provide enhanced water quality treatment of site runoff. 6. Students from Petro Vista will talk to Renton School District schools, including Benson Elementary located at ll61h Avenue Southeast and Southeast l861h Street. There are no shoulders or sidewalks along IIStlt Avenue Southeast south of the plat, but the roadway only carries a moderate amount of traffic. An alternative route further west via Petrovitsky Road and 1161h Avenue Southeast provides better walking facilities but is characterized by more traffic. In view of the small size of the plat in the context of an area-wide lack of walking facilities, it is not appropriate to require the Applicant to cure this neighborhood deficiency. CONCLUSIONS: I. If approved subject to the conditions imposed below, the proposed subdivision makes appropriate provision for the public health, safety and welfare; serves the public use and interest; and meets the requirements ofRCW 58.17.110. 2. The conditions of approval imposed herein, including dedications and easements, will provide improvements that promote legitimate public purposes, are necessary to serve the subdivision and are proportional to its impacts; are required to make the proposed plat reasonably compatible with the environment; and will carry out applicable state laws and regulations and the laws, policies and objectives of King County. DECISION: The preliminary plat application for Petro Vista, as revised and received on February 26, 2004, is APPROVED, subject to the following conditions of final plat approval: I. Compliance with all platting provisions of Title 19 of the King County Code. 2. All persons having an ownership interest in the subject property shall sign on the face ofthe final plat a dedication that includes the language set forth in King County Council Motion No. 5952. L03P0007~Biller Subdivision 4 3. The plat shall comply with the base density (and minimum density) requirements of the R-6-S0 zone classification. All lots shall meet the minimum dimensional requirements of the R-6 zone classification or shall be as shown on the face of the approved preliminary plat, whichever is larger, except that minor revisions to the plat which do not result in substantial changes may be approved at the discretion ofthe Department of Development and Environmental Services. 4. All construction and upgrading of public and private roads shall be done in accordance with the King County Road Standards established and adopted by Ordinance No. 11187, as amended (1993 KCRS). 5. The Applicant must obtain the approval of the King County Fire Protection Engineer certifYing the adequacy of the fire hydrant, water main, and fire flow to meet the standards of Chapter 17.08 of the King County Code. 6. Final plat approval shall require full compliance with the drainage provisions set forth in King County Code 9.04. Compliance may result in reducing the number andlor location oflots as shown on the preliminary approved plat. Preliminary review has identified the following conditions of approval which represent portions of the drainage requirements. All other applicable requirements in KCC 9.04 and the Surface Water Design Manual (SWDM) must also be satisfied during engineering and final review. a. Drainage plans and analysis shall comply with the 1998 King County Surface Water Design Manual and applicable updates adopted by King County. DOES approval of the drainage and roadway plans is required prior to any construction. b. Current standard plan notes and ESC notes, as established by ODES Engineering Review, shall be shown on the engineering plans. c. The following note shall be shown on the final recorded plat: All building downspouts, footing drains, and drains from all impervious surfaces such as patios and driveways shall be connected to the permanent storm drain outlet as shown on the approved construction drawings # on file with DDES andlor the King County Department of Transportation. This plan shall be submitted with the application of any building permit. All connections of the drains must be constructed and approved prior to the final building inspection approval. For those lots that are designated for individual lot infiltration systems, the systems shall be constructed at the time of the building permit and shall comply with plans on file." d. Storm water facilities shall be designed using the KCRTS Level One Flow Control standard. Water quality facilities shall also be provided using the Sphagnum bog protection menu. As shown on the conceptual drainage plan, the outlet of the detention pond and water quality facility will connect to the existing conveyance system along Petrovitsky Road and small areas of un detained flows will be used to maintain wetland hydrology within Tract B. Based upon the final drainage analysis, the size of the proposed drainage tracts may have to increase to accommodate the required detention storage volumes and water quality facilities. All runoff control facilities shall be located in a separate tract and dedicated to King County. unless portions ofthe drainage tract are used for recreation space in accordance with KCC 2IA.14.180. L03P0007~Biller Subdivision 5 e. The final drainage analysis shall evaluate the requirements for off-site bypass as outlined in the drainage manual on page 1-36. As noted in the design criteria, the contribution of flows to an onsite wetland must be maintained and the natural attenuation of flows under pre-developed conditions must also remain. The design engineer shall evaluate all areas which may contribute offsite flows including the ditch along 118 th Avenue SE. As noted in the applicants Level One Offsite analysis dated May 15, 2003, during major storm events the onsite wetland fills up and overtops to Petrovitsky Road and also backs up water across the south property line. The design engineer shall evaluate any potential flooding issues and provide drainage designs which adequately prevent potential drainage problems. As shown on the preliminary plat, an interceptor swale is proposed along the south property line oflots 10 and 11. f. The final drainage plans and technical reports shall evaluate all applicable design criteria for onsite closed depressions and ponding areas as discussed in the drainage manual on page 3-54. The existing wetland in Tract B currently captures surface water from offsite areas and the western portion of the project area which may influence the storm water modeling for pre-and post-developed flow rates and volumes. During final engineering review, King County will review and determine how much offsite flow andlor undetained project areas may drain to the wetland in Tract B without pretreatment in detention or water quality facilities. g. The final engineering plans and recorded plat shall show the 100-year floodplain boundaries as required by Special Requirements No.2 in the drainage manual. 8. The proposed subdivision shall comply with the 1993 King County Road Standards (KCRS) including the following requirements: a. Southeast 176th Court shall be improved as an urban subaccess street. b. One hundred eighteen ( 1 18 th ) Avenue Southeast shall be improved as an urban neighborhood collector along the frontage of the subject property. As noted in KCRS 2.03, for neighborhood collector streets intersecting with an arterial (SE Petrovitsky), the width must be 36-feet wide for the first 150 feet. A 25-foot right-of-way line radius is also required as shown in KCRS 2.10. c. One hundred eighteen (I 18 th ) Avenue SE is designated a neighborhood collector street which may require designs for bus zones and tum outs. As specified in KCRS 2.16, the applicant or his engineering consultant shall contact Metro and the local school district to determine specific requirements. d. Street illumination shall be provided at intersections with arterials in accordance with KCRS 5.05. f. Modifications to the above road conditions may be considered by King County pursuant to the variance procedures in KCRS 1.08. 9. During preliminary site inspections, King County has identified fill material, building debris, and a concrete foundation within the site. To address the required site grading and designs for development, the applicant shall submit a geotechnical report with the engineering plans to address all applicable earthwork, site preparation, road construction, and utility installation. The L03P0007-Biller Subdivision 6 geotechnical engineer shall also evaluate the soil conditions and requirements for the proposed storm water vault located within Tract A. Structural plans and calculations for the vault must be prepared by a licensed structural engineer. 10. All utilities within proposed rights-of-way must be included within a franchise approved by the King County Council prior to final plat recording. II. King County Code 16.82.150D requires seasonal limitations for construction within the Soos Creek basin. During the period October I through March 31, clearing and grading is not allowed unless certain provisions are complied with as outlined in the code. The applicants engineering plans shall demonstrate compliance with the applicable code requirements and provide notes referencing the seasonal limitations set forth in KCC 16.82.150D. 12. The applicant or subsequent owner shall comply with King County Code 14.75, Mitigation Payment System (MPS), by paying the required MPS fee and administration fee as determined by the applicable fee ordinance. The applicant has the option to either: (I) pay the MPS fee at final plat recording, or (2) pay the MPS fee at the time of building permit issuance. If the first option is chosen, the fee paid shall be the fee in effect at the time of plat application and a note shall be placed on the face of the plat that reads, "AII fees required by King County Code 14.75, Mitigation Payment System (MPS), have been paid." If the second option is chosen, the fee paid shall be the amount in effect as ofthe date of building permit application. 13. Lots within this subdivision are subject to King County Code 2IA.43, which imposes impact fees to fund school system improvements needed to serve new development. As a condition of final approval, fifty percent (50%) of the impact fees due for the plat shall be assessed and collected immediately prior to recording, using the fee schedules in effect when the plat receives final approval. The balance of the assessed fee shall be allocated evenly to the dwelling units in the plat and shall be collected prior to building permit issuance. 14. There shall be no direct vehicular access to or from IISth Avenue SE from those lots which abut it, except lot 23. A note to this effect shall appear on the engineering plans and final plat. 15. The proposed subdivision shall comply with the Sensitive Areas Code as outlined in KCC 2IA.24. Permanent survey marking, and signs as specified in KCC 2 IA.24.1 60 shall also be addressed prior to final plat approval. Temporary marking of sensitive areas and their buffers (e.g., with bright orange construction fencing) shall be placed on the site and shall remain in place until all construction activities are completed. Preliminary plat review has identified the following specific requirements which apply to this project. All other applicable requirements from KCC 21 A.24 shall also be addressed by the applicant. a. The Class I wetland near the east property line shall have a minimum buffer of 100 feet, measured from the wetland edge. b.

HISTORY/BACKGROUND: The Subdivision Technical Committee (STC) of King County has conducted an on-site examination of the subject property. The STC has discussed the proposed development with the applicant to clarify technical details of the application, and to determine the compatibility of this project with applicable King County plans, codes, and other official documents regulating this development. As a result of preliminary discussions, the applicant presented the Technical Committee with a revised plat on February 26, 2004. The primary modifications include: • Accurate delineation of the on-site wetlands • Minor rearrangements of lots • Provision of a larger drainage and water quality facility D. THRESHOLD DETERMINA nON OF ENVIRONMENTAL SIGNIFICANCE: Pursuant to the State Environmental Policy Act (SEPA), RCW 43.21 C, the responsible official of the LUSD issued a mitigated threshold determination of non-significance (MDNS) for the proposed development on March IS, 2004. This determination was based on the review of the environmental checklist and other pertinent documents, resulting in the conclusion that the proposal would not cause probable significant adverse impacts on the environment provided the following measures are complied with: 1. A fourjoot tall fence shall be constructed along the edge of the sensitive Area Tracts B and C. The fence shall follow the common boundaries of the wetland tracts and the adjoining lots and road. 2. Fencing details, construction and location shall be shown on the engineering plans for DDES review and approval. This mitigation is intended to reduce disturbance within the protective buffer and associated wetland. 3. All existing structures and other derbies shall be removed from the sensitive area tracts and the area shall be restored in accordance with KCC 21A.24. Agencies, affected Native American tribes and the public were offered the opportunity to comment on or appeal the determination for 21 days. Neither the MDNS nor the specific mitigation measures were appealed by any party, including the applicant, and they have been incorporated as part of the applicant's proposal. E.

METRO: No response. LC2P0012, Petre vis:::a Staff rpt. - 2 - F. NATURAL ENVIRONMENT: I. Topography: The site slopes down moderately from southwest to northeast. The maximum slope is less than 20%. 2. Soils: One surface soil is found on this site per King County Soil Survey, 1973. the entire site is classified AgB AgB -Alderwood gravely, sandy loam; 0-6% slopes. Runoff is slow and the erosion hazard is slight. This soil type has a moderate limitation for low building foundations due to a seasonally high water table, and severe limitations for septic tank filter fields due to very slow permeability in the substratum. 3. Wetland/streams: Two wetland reports were prepared by Wiltermood Associates, Inc. and LeRoy Surveyors & Engineers, Inc. The King County Wetland Ecologist reviewed the reports and conducted a field visit. Two wetland areas were identified on the site. The area in the north central portion of the site is classified as a Class II wetland. The area near the east property line of the site and extending east outside of the site is classified as a Class I wetland. There is a Class 2S stream a few feet east of the site. The site lies within the Soos Creek drainage basin. 4. Vegetation: This site is moderately covered by second-story vegetation and groundcover consists of Northwest native species. 5. Wildlife: Small birds and animals may inhabit this site; however, their population and species are limited due to nearby development. No threatened or endangered species are known to exist on or near the property. 6. Mapped Sensitive Areas: The Sensitive Areas Map Folio indicates that the Soos Creek Inventoried Wetland 5402 is located a few miles east of the site. An off site Class II fish bearing stream also runs east of the site. G. NEIGHBORHOOD CHARACTERISTICS: The property lies within a rapidly developing neighborhood south of SE Petrovisky Road and east of Benson Highway. The site abuts 1 1 8th Avenue SE and SE Petrovisky Road to the west and north respectively. A 25-foot wide Bonneville Power Administration transmission line easement runs east of the site. There are residential parcels directly south of the site developed with residential structures. The site itself is developed with an office and storage buildings which will all be removed. The site and the surrounding parcels to the west, south and east are zoned R-6. The area north of SE Petrovisky Road is zoned R-18. H. SUBDIVISION DESIGN FEATURES: I. Lot Pattern and Density: The proposed lot and street layout is in conformance with the King County Subdivision and Zoning Codes 2. Internal Circulation: All the lots within the subdivision except Lot 23 will have access to ll8th Avenue SE via a subaccess road (SE 176th Court) which will be constructed as part of this subdivision. Lot 23 will have direct access to SE I I 8th Avenue SE. SE 176 th Court will extend east from 118 th Avenue SE at mid width of the site and terminate in a cul-de-sac near the east end of the site. 3. Roadway Section: The interior road and the site's frontage with 116 th Avenue SE will be improved to urban road standards consisting of curb, gutter and sidewalks. 4. Drainage: The proposed development site contains two primary drainage subbasins. The east portion of the property drains to an offsite wetland and stream corridor which comprises portions of the headwater for Soos Creek. The western portion of the site drains to an onsite wetland located within proposed Tract B as shown on the site plan. As described in the applicant's preliminary drainage analysis, the onsite wetland functions as a closed depression which captures surface water within the project and L02P0012, Petro Vista Staff rpt. - 3 - also collects drainage from offsite areas located south of the property. The closed depression has some capacity to detain and infiltrate water, however, during major storm events the wetland fills up and overtops into the right-of-way for Petrovitsky Road. Based upon the applicant's discussion with property owners living south of the project, the drainage from the closed depression also backs up across the south property line. To assure that site development will provide adequate controls for surface water, the applicant is proposing a storm water detention facility located adjacent to the onsite wetland. This facility will collect and detain the majority of onsite storm water before discharge from the site. An outlet from the facility will be provided to convey storm water to the existing pipe system along Petrovitsky Road, which discharges surface water to the wetland and stream corridor located east of the site. To reduce the existing nooding condition of the onsite wetland, a small amount of runoff will be conveyed to the wetland to provide surface water to support wetland hydrology without causing nooding of surrounding property. As shown on the preliminary site plan, a drainage interceptor will be provided along the south property line to collect offsite storm water for safe conveyance to the wetland. The larger volumes of storm water caused by site development will be collected into the storm water facility before discharge to the downstream system east of the site, rather than discharge to the onsite closed depression. During King County evaluation of downstream drainage conditions, a bog wetland was identified as part of the Soos Creek stream corridor. For site development which drains to an identified bog, the King County drainage manual requires that special water quality facilities must be provided to treat storm water prior to discharge from the site. To accomplish the water quality designs, the applicant's drainage plan shows a combination sand filter and compost filter adjacent to a storm water detention vault. Detailed designs for these facilities will be provided during final review when the applicant submits construction plans for site development. After the construction and inspection process, King County will ultimately own and maintain the drainage and water quality facilities. 5. Other Design Features: The proposal includes a combined recreation and storm facility tract. The storm facility tract will include a water quality feature per the KCSWDM. The storm detention and water quality facility will be constructed underground. The recreation improvement will be placed above the drainage facility. I. TRANSPORTATION PLANS: I. Transportation Plans: The King County Transportation Plan indicates that SE Petrovisky Road is designated as a principal arterial and 1 I 8th Avenue SE as a neighborhood collector. The subject subdivision is not in connict with this plan. 2. Subdivision Access: The subdivision will have access to SE Petrovisky Road a principle, arterial via I I 8th Avenue SE immediately west of the site. 3. Traffic Generation: It is expected that approximately 230 vehicle trips per day will be generated with full development of the proposed subdivision. This calculation includes service vehicles (i.e., mail delivery, garbage pick-up, school bus) which may currently serve this neighborhood, as well as work trips, shopping, etc. 4. Adequacy of Arterial Roads: This proposal has been reviewed under the criteria in King County Code 14.70, Transportation Concurrency Management; 14.80, Intersection Standards; and King County Code 14.75; Mitigation Payment System. a. King County Code 14.70 -Transportation Concurrency Management: The Transportation Certificate of Concurrency (#01386) dated March 27, 2002 indicates that transportation improvements or strategies will be in place at the time of development, or that a financial commitment is in place to complete the improvements or strategies within six (6) years, according to RCW 36.70A.070(6). I.07P0012, Petro Vista Staff rpt. - 4 - b. King County Code 14.80 -Intersection Standards: The traffic generated by this subdivision falls below the threshold requiring mitigation. The existing arterial system will accommodate the increased traffic volume generated by this proposal. c. King County Code 14.75 -Mitigation Payment System: King County Code 14.75, Mitigation Payment System (MPS), requires the payment of a traffic impact mitigation fee (MPS fee) and an administration fee for each single family residential lot or unit created. MPS fees are determined by the zone in which the site is located. This site is in Zone(s) 342 per the MPS/Quartersection list. MPS fees may be paid at the time of final plat recording, or deferred until building permits are issued. The amount of the fee will be determined by the applicable fee ordinance at the time the fee is collected. J. PUBLIC SERVICES: l. Schools: This proposal has been reviewed under RCW 58.17.110 and King County Code 21A.28 (School Adequacy). a. School Facilities: The subject subdivision will be served by Benson Hill Elementary, Nelsen Junior High, and Lindbergh Senior High Schools, all located within the Renton School District. b. School Capacity: The Renton School Board has adopted capacity figures which indicate their ability to accommodate additional students. c. School Impact Fees: Ordinance 14525 requires that an impact fee per lot be imposed to fund school system improvements to serve new development within this district. Payment of this fee (in a manner consistent with KCC 21A.43 will be a condition of subdivision approval. d. School Access: The Renton School District has indicated that the future students from this subdivision will walk to all schools. The District has a policy to provide bus service to elementary school children if they live more than one mile from the school. The bus service for junior high and senior high school students is provided for residents living more than 1.5 and 2 miles from such schools respectively. Walkway conditions to the elementary school and the junior high school are substandard. There are sidewalks along the south side of SE Petrovisky Road from the site to 116 th Avenue SE and an average 2-foot wide paved shoulder along I I 6th Avenue SE to the elementary school site. 2. Parks and Recreation Space: The nearest public park is Soos Creek Trail Park located a few miles east of the site. KCC 21 A.14 requires subdivisions in the UR and R zone classifications to either provide on-site recreation space or pay a fee to the King County Parks Division for establishment and maintenance of neighborhood parks. At this time, the applicant is proposing to provide a recreation tract which will be combined with the drainage facility tract. KCC 21 A.14.190 requires subdivisions to provide tot/children play areas within the recreation space on-site. The applicant proposes to construct the drainage facility under ground and create a recreation space above it. 3. Fire Protection: The Certificate of Water Availability from Soos Creek Water and Sewer District indicates that water is presently available to the site in sufficient quantity to satisfY King County Fire Flow Standards. Prior to final recording of the plat, the water service facilities must be reviewed and approved per King County Fire Flow Standards. K. UTILITIES: 1. Sewage Disposal: The applicant proposes to serve the subject subdivision by means of a public sewer system managed by Soos Creek Water & Sewer District. A Certificate of :"'02POClL, Petro Vista Staff rpt. - 5 - Sewer Availability, dated May 8, 2002 indicates this sewer district's capability to serve the proposed development. 2. Water Supply: The applicant proposes to serve the subject subdivision with a public water supply and distribution system managed by Soos Creek Water and Sewer District. A Certificate of Water Availability, dated May 8, 2002 indicates this district's capability to serve the proposed development. L. COMPREHENSIVE AND COMMUNITY PLAN: I. Comprehensive Plan: This proposal is governed by the 1994 King County Comprehensive Plan which designates this area as Urban. The proposed subdivision is not in conflict with the policies of the Comprehensive Plan. 2. Special Overlay District: The proposed site is subject to the tree retention requirement. The majority of the significant trees are located within the sensitive area tracts. The applicant states that the number of significant trees within the sensitive area tracts are more than 30 percent of alI the significant trees on site, thus meeting the requirement for the significant tree retention. M. ST ATUTES/CODES: If approved with the recommended conditions in this report, the proposed development wilI comply with the requirements ofthe County and State Platting Codes and Statutes, and the lots in the proposed subdivision will comply with the minimum dimensional requirements of the zone district. N. ANALYSIS: The Subdivision Technical Committee (STC) has not identified any significant issues involved in the preliminary review and recommendations of this proposal. The STC recognizes that there are substandard walkway facilities from the site to the Benson HilI Elementary school iftbe children use 118 th Avenue SE. There are no sidewalks or walkways along this road. However, the elementary students from this area could use the sidewalk on the south side ofSE Petrovitsky Road and the 2 -to-3-foot paved shoulder along 116 th Avenue SE to reach the school site. The subject site appears to be more that one mile from Benson Elementary school. It would be appropriate that the elementary school children be bussed from the site to the school since they have to cross I I 6th Avenue SE, which is a busy street. O. CONCLUSIONS: The subject subdivision will comply with the goals and objectives of the King County Comprehensive Plan and will comply with the requirements of the Subdivision and Zoning Codes and other official land use controls of King County, based on the conditions for final plat approval. P. RECOMMENDATIONS: It is recommended that the subject subdivision, revised and received February 26, 2004 be granted preliminary approval subject to the folIowing conditions of final approval: I. Compliance with all platting provisions of Title 19 of the King County Code. 2. All persons having an ownership interest in the subject property shall sign on the face of the final plat a dedication that includes the language set forth in King County Council Motion No. 5952. ~:J2?:JO:C2, Pet~o Vista Staff rpt. - 6 - 3.

This plan shall be submitted with the application of any building permit. All connections of the drains must be constructed and approved prior to the final building inspection approval. For those lots that are designated for individual lot infiltration systems, the systems shall be constructed at the time of the building permit and shall comply with plans on file." d. Storm water facilities shall be designed using the KCRTS Level One Flow Control standard. Water quality facilities shall also be provided using the Sphagnum bog protection menu. As shown on the conceptual drainage plan, the outlet of the detention pond and water quality facility will connect to the existing conveyance system along Petrovitsky Road and small areas of undetained flows will be used to maintain wetland hydrology within Tract B. Based upon the final drainage analysis, the size of the proposed drainage tracts may have to increase to accommodate the required detention storage volumes and water quality facilities. All runoff control facilities shall be located in a separate tract and dedicated to King County unless portions of the drainage tract are used for recreation space in accordance with KCC 2IA.14.180. e. The final drainage analysis shall evaluate the requirements for off-site bypass as outlined in the drainage manual on page 1-36. As noted in the design criteria, the contribution of flows to an on site wetland must be maintained and the natural attenuation of flows under pre-developed conditions must also remain. The design engineer shall evaluate all areas which may contribute offsite flows including the ditch along IISth Avenue SE. As noted in the applicants Level One Offsite analysis dated May 15,2003, during major storm events the onsite wetland fills up and overtops to Petrovitsky Road and also backs up water across the south property line. The design engineer shall evaluate any potential flooding issues and provide drainage designs which adequately prevent potential drainage LC2P0012, Petro Vis:a Staff rpt, - 7 - problems. As shown on the preliminary plat, an interceptor swale is proposed along the south property line of lots 10 and 11. f. The final drainage plans and technical reports shall evaluate all applicable design criteria for onsite closed depressions and ponding areas as discussed in the drainage manual on page 3-54. The existing wetland in Tract B currently captures surface water from offsite areas and the western portion of the project area which may influence the storm water modeling for pre and post developed flow rates and volumes. During final engineering review, King County will review and determine how much offsite flow and/or undetained project areas may drain to the wetland in Tract B without pretreatment in detention or water quality facilities. g. The final engineering plans and recorded plat shall show the 100-year floodplain boundaries as required by Special Requirements No.2 in the drainage manual. 8. The proposed subdivision shall comply with the 1993 King County Road Standards (KCRS) including the following requirements: a. Southeast I 76 th Court shall be improved as an urban subaccess street. b. One hundred eighteen (1ISth) Avenue Southeast shall be improved as an urban neighborhood collector along the frontage of the subject property. As noted in KCRS 2.03, for neighborhood collector streets intersecting with an arterial (SE Petrovitsky), the width must be 36-feet wide for the first 150 feet. A 25-foot right-of-way line radius is also required as shown in KCRS 2.10. c. One hundred eighteen (1lSth ) Avenue SE is designated a neighborhood collector street which may require designs for bus zones and turn outs. As specified in KCRS 2.16, the applicant or his engineering consultant shall contact Metro and the local school district to determine specific requirements. e. Street illumination shall be provided at intersections with arterials in accordance with KCRS 5.05. f. Modifications to the above road conditions may be considered by King County pursuant to the variance procedures in KCRS 1.08. 9. During preliminary site inspections, King County has identified fill material, building debris, and a concrete foundation within the site. To address the required site grading and designs for development, the applicant shall submit a geotechnical report with the engineering plans to address all applicable earthwork, site preparation, road construction, and utility installation. The geotechnical engineer shall also evaluate the soil conditions and requirements for the proposed storm water vault located within Tract A. Structural plans and calculations for the vault must be prepared by a licensed structural engineer. 10. All utilities within proposed rights-of-way must be included within a franchise approved by the King County Council prior to final plat recording. 11. King Connty Code 16.82.1500 requires seasonal limitations for construction within the Soos Creek basin. During the period October I through March 31, clearing and grading is not allowed unless certain provisions are complied with as outlined in the code. The applicants engineering plans shall demonstrate compliance with the applicable code requirements and provide notes referencing the seasonal limitations set forth in KCC 16.82.1500. 12. The applicant or subsequent owner shall comply with King County Code 14.75, Mitigation Payment System (MPS), by paying the required MPS fee and administration fee as determined by the applicable fee ordinance. The applicant has the option to either: (1) pay the MPS fee at final plat recording, or (2) pay the MPS fee at the time of building permit issuance. If the first option is chosen, the fee paid shall be the fee in effect at the time of plat application and a note shall be placed on the face of the plat that reads, "All fees required by King County Code 14.75, Mitigation Payment System (MPS), have been L02P8012, Petro vis~a Staff rpt. -s - paid." Tfthe second option is chosen, the fee paid shall be the amount in effect as of the date of building permit application. 13. Lots within this subdivision are subject to King County Code 2IA,43, which imposes impact fees to fund school system improvements needed to serve new development. As a condition of final approval, fifty percent (50%) of the impact fees due for the plat shall be assessed and collected immediately prior to recording, using the fee schedules in effect when the plat receives final approval. The balance of the assessed fee shall be allocated evenly to the dwelling units in the plat and shall be collected prior to building permit lssuance. 14. There shall be no direct vehicular access to or from IISth Avenue SE from those lots which abut it except lot 23. A note to this effect shall appear on the engineering plans and final plat. 15. The proposed subdivision shall comply with the Sensitive Areas Code as outlined in KCC 21 A.24. Permanent survey marking, and signs as specified in KCC 21A.24.160 shall also be addressed prior to final plat approval. Temporary marking of sensitive areas and their buffers (e.g., with bright orange construction fencing) shall be placed on the site and shall remain in place until all construction activities are completed. Preliminary plat review has identified the following specific requirements which apply to this project. All other applicable requirements from KCC 21A.24 shall also be addressed by the applicant. a. The Class I wetland near the east property line shall have a minimum buffer of 100 feet, measured from the wetland edge. b. the Class 2 wetland near the north boundary of the site shall have a minimum buffer of 50 feet, measured from the wetland edge. c. The Class 2S stream shall have a minimumlOO-foot buffer, measured from the ordinary high water mark (OHWM). d. The stream, wetlands and their respective buffers shall be placed in a Sensitive Area Tract (SAT). e. A minimum building setback line of 15 feet shall be required from the edge of the tract. f. Buffer width averaging may be allowed by King County if it will provide additional protection to the wetland/stream or enhance there functions, as long as the total area contained in the buffer on the development proposal site does not decrease. In no area shall the buffer be less than 65 percent of the required minimum distance. To ensure such functions are enhanced a mitigation plan will be required for the remaining on-site sensitive areas. An enhancement plan shall be submitted for review during engineering review. g. A mitigation plan and financial guarantee/bond will be required for any proposed impacts of sensitive areas including buffers. The bond amount will include all components of the mitigation plan including, but not limited to, plantings, grading, fencing, signs, inspections, and monitoring for five years. h. Prior to commencing construction activities on the site, the applicant shall temporarily mark sensitive areas Tract(s) in a highly visible manner, and these areas must remain so marked until all development proposal activities in the vicinity of the sensitive areas are completed. 1.

If appropriate, state what stream or river it ffows into. There is a small (approximately 0.12 acre) Class 2 Wetland on site and a 0.7 acre Class 1 Wetland adjacent to the NW corner of the property. A Class 2 Stream flows through the offsite wetland and continues flowing as a stream towards a southeast direction. 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 for this work. Although there may be some construction work within 200 feet of the wetlands and Class 2 stream, buffers will be stringently protected. The applicant is requesting a buffer reduction up to a maximum of 35 feet from the offsite Class 1 wetland. The applicant has proposed to design an averaged buffer tract of 27,625 SF for the Class 1 wetland. A 100-foot buffer would require the applicant to create a tract of 25,809 SF. 3. Estimate the amount of fill and dredge material that would be placed in or removed from surface water of wetfands and indicate the area of the site that would be affected. Indicate the source of fiff material. Not applicable. 4. Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. Not to our knowledge, 5. Does the proposal lie within a 100-year ffoodplain? If so, note location on the site plan. Water will pond in the onsite wetland during a 100 year storm event. 4 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. None anticipated b. Ground Water: i. Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities of withdrawals or discharges, if known. None anticipated. 2.

None anticipated; site is to be served by sewer. c. Water Runoff (including storm water): 1. Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. The only source of runoff anticipated will be from the impervious surfaces created by the construction of residences and public roads. Drainage from roads and driveways will be collected via public storm drains and routed to a combination detention pond/wetpool facility. Drainage from residential structures will be routed to individual downspout dispersion systems or perforated stUb-out connections. 2. Could waste material enter ground or surface waters? If so, generally describe. Not to our knowledge. d. Proposed Measures to reduce or control surface, ground, and run off water impacts, if any: All work on the site will be in conformance with local, State & Federal codes and regulations. 4. PLANTS a.

Green CONTACT: Jim Job EXPIRES: 4-22-2003 Location The property is located in Renton, King County, Washington, at the SE corner of S.E. Petrovitsky Road and 118111 Avenue S.E. Section 33, Township 23 N, Range 5 E, WM. The project is located in the upper portion of the Upper Soos Creek drainage basin. Project Description The property owners are proposing to develop and subdivide the slightly less than four acre site into 23 single-family residential lots. Site Description The property consists of King County Parcels 6196600380 and 6196600381. It is bordered to the north by S.E. Petrovitsky Road (S.E. 176th St.), to the west by 118111 Ave. S.E., and to the east by a BPA power line right-of- way. There is an office building, a garage, a shed and an equipment yard located on the eastern half of the property. The land slopes down towards the center from the buildings, and the western and southern sides to create a small depression located in the north half of the property. This depression contains a small (approximately 0.12 acre) Class 2 Wetland. The onsite wetland is dominated by Scrub-Shrub vegetation [predominaritly red-osier dogwood (Comus sericea)] with a developing forested class [predominantly Oregon ash (Fraxinus latifolia) and black cottonwoods (Populus balsamifera)]. The upland has areas of Himalayan blackberries (Rubus procerus), mixed young forest dominated by Douglas firs (Pseudotsuga menziesii) and black cottonwoods, and open grassy areas. On the east side of the buildings, the land slopes down to the eastern border. This hillside is dominated by black cottonwoods with an understory dominated by trailing blackberries (Rubus ursin us) and snowberries (Symphoricarpos albus). An offsite Class 3 Wetland (0.7 acre) skirts the eastern border for approximately 200 ft, at which point it veers offsite to the east. The offsite wetland is primarily a reed canarygrass meadow (Phalaris arundinacea), with isolated Scrub-Shrub clusters [predominantly spirea (Spirea douglasil) and Pacific willow (Salix lucida)] and a Scrub-Shrub fringe [predominantly Himalayan blackberry and western crabapple (Malus fusca )]. The majority of the wetland is located on the BPA power line right-of-way. The onsite wetland lacks an obvious inlet or outlet, but it may occasionally flood up to S.E. Petrovitsky Road. Water flows through the offsite wetland as a small seasonal stream that enters from a culvert on the north edge and exits through a culvert at the south edge. The outflow from the offsite wetland feeds a small wetland to the south (King County Sensitive Areas Wetland Map 5, Wetland number 1 OB). The soils on the property are mapped as Alderwood gravelly sandy loam, 6-15% slopes (upland areas) and Norma sandy loam, 0-2% slopes (wetland areas), by the Soil Conservation Service (U.S. Department of Agriculture, 1973). The soil types have been confirmed by site visits. The King County GIS data depicts a floodplain and stream through the center of the project. The topographic map and digital pictures clearly show this to be inaccurate. These areas should be shifted to the Northeast corner of the proposed project where the stormwater from Petrovitsky Road is released. Level 1 Downstream Analysis We visited the site on two occasions, February 15, 2000 and February 22, 2000. It was cloudy but dry the first visit to the site. It was raining moderately on the second visit. On both occasions, there was no standing water observed in the on-site wetland. The stormwater from the site will be collected in a closed pipe network and deposited in a detention pond located easterly of the on-site wetland. The stormwater will be released into the on-site wetland at rates less than or equal to the pre-developed rates. The Norma soil listed above tends to be one of the more permeable wetland soils. If the stormwater were to fill this on-site wetland, it would have to get approximately 5 feet deep. The stormwater would sheet flow across the sidewalk located along the north property line and into the closed pipe system located in Petrovitsky Road. The stormwater would travel approximately 275 feet in this closed pipe system. The stormwater is deposited into the off-site wetland located in the BPA transmission line R-O-W. The stormwater meanders in a southeasterly direction through the off-site wetland and the SPA R-O-W for approximately 300 feet to a 1 O-inch diameter culvert. The stormwater continues southeasterly for another 200 feet. At this point, it begins to change direction and travels easterly for approximately 600 feet to a 36 inch diameter corrugated metal culvert under 122nd Avenue. This is where it meets the headwaters of the Big Soos Creek and continues in a southerly direction. I" ' A ~ ~. ) 20000 ~ ....

Engineering Manager LeRoy Surveyors and Engineers, Inc. 1103 Shaw Road Puyallup, W A 98374 RE: Storm Drainage Analysis and Preliminary Design Petro Vista Plat 11925 S.E. Petrovitsky Road, King County, Washington Our Job No. 1I0ll Dear Paul: Enclosed you will find a package of material that outlines our recommendations for the revised storm drainage design system for the Petro Vista Plat. Within this package you will find the following documents. 1. Project issues list outlining the general drainage requirements to be implemented on the site 2. Preliminary redline design plan of the pond and water quality facility 3. Preliminary storm drainage and water quality calculations for the detention system The general project issues list outlines our general concerns with the revisions needed for this project. I would like to further explain some of the items that you need to be aware of with this revised preliminary design. The water quality facility as listed in King County's manual is a three-system facility. As mentioned, it includes detention and water quality pond, as well as a sand filter and a compost filter. • Please be aware the sand filter is rather large; however, we have squeezed the size as much as possible with the intent of meeting the King County stormwater manual requirements. • The open pond facility appears to work within the area outlined, however, it does require some retaining walls or reinforced rockeries that may be five or six feet in height to accommodate this footprint. We have utilized 3 horizontal to 1 vertical side slopes on the interior pond although these may need to be steepened to 2 horizontal to 1 vertical, depending on the final design constraints. • As you will notice in the calculations, we have used the outlet elevations as shown on the enclosed hand drawn cross-section. With an outlet elevation of 402.8, it appears the maximum water surface elevation for the detention facility is approximately 411.0 based on our design sketch. This in tum means that the lot pad areas must be at elevation 412 or above. It appears this predominantly affects Lots 15, 16, and 17. which are well below this 18215 72ND AVENUE SOUTH KENT.

Engineering Manager LeRoy Surveyors and Engineers, Inc. -2-October 13,2003 elevation. As a recommendation, you can either fill these lots to the required elevation and pipe these lots to the storm drainage detention pond facility or possibly route a downspout line into the wetland buffer area leaving the lots lower in elevation, which is better for earthwork purposes. However, once these three lots are considered bypass, the pond gets larger. This is important since this pond barely meets the requirements for volume of a Level One Flow Control facility. • The sand filter as outlined on the plan is rather large but can be utilized in conjunction with a sport court or other park-type facility on the top. This will help meet some of your park requirements that King County is requiring for this project. • The compost filter is shown in concept only. The size is not exactly determined; however, based on past experiences the one outlined is probably in the vicinity of the size needed. The location also may need to be on the other side of the sand filter adjacent to the potential outlet pipe. This has some flexibility since the size is quite smaller than the sand filter. • Please review your road profiles, keeping in mind the stopping sight distance the County requires. They look at this very closely. If you cannot make the required stopping sight distance, try to process a variance to utilize a streetlight. • Since we are not discharging the entire developed site directly into the on-site Tract B wetland, we feel that basic Level One Flow Control for the detention requirements is adequate. The County may, however, disagree with this based on their own review of the overall system. If this is the case the pond will obviously get bigger. Based on our analysis of the storm drainage manual, Level One Flow Control is the standard to be utilized on this project. Please review the enclosed information, calculations, and documents and determine whether you need any further assistance from our office. We would be more than happy to assist you with further analysis and/or design of the preliminary, as well as the final construction plans if you so desire. If you have any question on the calculations, please feel free to contact me or Joe Hopper of this office. HPG/dm llOIlc.OO2.doc enc: As Noted Respectfully, 1IJf~~ Hal P. Grubb, P.E. Director of Engineering Services cc: Joseph M. Hopper, Barghausen Consulting Engineers, Inc. Project issues or changes needed to satisfy King County road and drainage requirements. Petro Vista BCE Job No. 11011 1. A three facility water quality system will need to be installed consisting of a Combined Detention / Water Quality Pond, a Basic Sand Filter, and a Leaf Compost Filter in series according to King County SWDM section 6.1.4. 2. Tract C and Lots 18 and 19 will need to be reconfigured to accommodate the Detention Pond, Sand Filter Vault and Leaf Compost Filter Vault. Lot 20 will need to be eliminated or moved to the front of the plat near lots 21-23. 3. An interceptor trench will need to be installed along the rear of lots 1-12 to convey upstream contributing areas through the proposed project to "recharge" the on-site wetland, and maintain the existing flow route. 4. A swale will need to be installed along the rear of lots 13-17 to divert upstream contributing areas away from the developed site to the creek/wetland to the east of the project. 5. The swale / ditch / low area between the on-site wetland and the creek/wetland to the east of the site along Petrovitsky Road will need to be re-graded to accommodate the outfall of the site detention/W.Q. system. An alternative to this would be to tight line a pipe system from the detention/W.Q. system to the east property line of lot 18, outletting to Tract D. 6. The grades along the road on the Grading Plan look as if the transition from the entrance to the steep section of road needs a larger vertical curve due to grade differentials. King County required stopping site distance along the road profile will need to be maintained thus the profile adjusted or a variance needs to be obtained from the county. ... .. • SECTION 6.1 WATER QUALITY MENUS 6.1.4 9/1198 SPHAGNUM BOG PROTECTION MENU Where applied: The Sphagnum Bog Protection menu7 covers sphagnum bog wetlands' greater than 0.25 acres in size" It applies to stonnwater conveyed by surface flow to the sphagnum bog vegetation community. If stonnwater is infiltrated by the project, or if the project is a redevelopment project. then the Basic WQ menu is applied unless the project is exempt from Core Requirement #8, "Water QUality." For precise details on the application of this and other area-specific water quality menus, refer to Section 1.2.8. Note: The Sphagnum Bog Protection menu is a stand-alone menu. It integrates the Basic WQ menu level of protection and the additional measures needed to achieve bog protection goals in the options described below. When this menu is required as specified in Core Requirement #8 (see Section 1.2.8), it is intended to replace the Basic WQ menu in areas draining to sphagnum bogs. Treatment goal: If surface water must be discharged to a bog, the treatment goal is to reduce total phosphate by 50 percent, reduce nitrate + nitrite by 40 percent, maintain alkalinity below 10 mg/L, and maintain pH below 6. Basis: In their undeveloped condition. bogs are isolated from surface water, being supplied almost solely by rainwater. The best strategy for protection of bog water quality is to infiltrate the water quality design volume while routing high flows around the bog. Although it is not known whether alkalinity or nitrogen can be reduced sufficiently by the options outlined below, there are no other technologically-feasible alternatives at this time. An experimental design adjustment (see Section 1.4) could be pursued as additional technology becomes available. o SPHAGNUM BOG PROlECll0N OPll0N 1 - LARGE WETPOND FOLLOWED BY LARGE SAND ALTER This option uses a large wetpond (see Section 6.4.1. p. 6-67) or a large combined detention and wetpond (see Section 6.4.2, p. 6-80), sized so that the wetpond volume is 4.5 times the volume of runoff from the mean annual stonn, rather than 3 times the volume as in the Basic Water Quality menu. A large sand filtration facility (see Section 6.5.2, p. 6-100, or 6.5.3, p. 6-120) must follow the pond. In orderto ensure that algae and sources of alkalinity from the pond are not washed from the pond into the bog, the sand filter must be the last facility. o SPHAGNUM BOG PROlEC110N OPll0N 2- STORMWAlER WETLAND IN SERIES WITH A LARGE SAND ALTER This option uses a storm water wetland (see Section 6.4.3, p. 6-86) or combined detention and stormwater wetland (see Section 6.4.4, p. 6-92) to remove solids and enhance the concentration of organic acids, and a large sand filter (see Section 6.5.2. p. 6-100) to remove the finer sediment for alkalinity and nutrient reduction. Tbe order of facilities is interchangeable since there are both advantages and disadvantages to having the sand filter last in the train. Note: A presettling cell is required if the first treatment facility is not preceded by a detention facility. 7 The Bog Protection menu targets a different set of pollutants than the Lake or Stream Protection menus. Since the targeted pollutants are more difficult to remove, use of larger and/or additional treatment facilities is required. 8 A sphagnum bog wetland is defined as a wetland having a predominance of sphagnum moss creating a substrate upon which a distinctive community of acid·loving plants is established (see -Definitions-for more detail). There are several classification schemes for wetlands dominated by sphagnum moss, and a successional series from conventional wetlands to fens to sphagnum bog is recognized by most ecologists. Some bioJogists use water chemistry and plant community composition to detennine where in this successional series a wetland should be placed. In these classification schemes, the sphagnum wetlands defined in this manual would be bogs. Others base the wetland type on the source of water, in which case most King County sphagnum wetlands would be fens. This manual has adopted the classification scheme based on water chemistry and plant communities and hence refers to these wetlands as bogs rather than fens. 9 The size of a sphagnum bog wetland is defined by the boundaries of the sphagnum bog plant community. 6-12 1998 Surface Water Design Manual • ) ) '---- • ,----... 6.1.4 SPHAGNUM BOG PROTECTION MENU 1:1 SPHAGNUM BOG PROTECTION OPTION 3- LARGE SAND FILTER IN SERIES WITH A LEAF COMPOST FILTER This option uses. a large sand filter or large sand filter vault followed by a leaf compost filter. Sizing specifications for the large sand filters can be found in Sections 6.5.2 (p. 6-100) and 6.5.3 (p. 6-120). Leaf compost filters are detailed in Section 6.5.5 (p. 6-131). The order of facilities is interchangeable since there are both advantages and disadvantages to having the leaf compost filter last in the train.

According to KCSWDM Core Requirement No.2 for flow control, Exemption No. 3C allows for the proposed basin to release the developed Ilows to the natural outlet without a formal flow control facility. The flow rate differences between the pre-developed and developed conditions are minor and the flow volumes should not be much larger due to the minimal addition of impervious roof surfaces that are proposed to be dispersed prior to outletting into the site wetland. There should not be an adverse effect to the on-site wetland from either storm Ilow rates or volumes.

A LCF removes pollutants through filtration, ion exchange, adsorption, and microbial degradation. Figure 6.5.5.A (p. 6-133) gives a schematic representation of a leaf compost filter. Applications and Limitations A leaf compost filter may be used as a second water quality facility in a stream protection treatment train (per Table 6.1.3.A, p. 6-11) or a bog protection treatment train (per Table 6.1.4.A, p. 6-13). Leaf compost filters are especially effective in situations where removal of metal contaminants is desired. LCFs may not be used as stand-alone facilities until more experience is gained with the system, particularly with potential for plugging or blinding and maintenance requirements. Stormwater TM Management has developed two basic types of compost filter: a vault style employing canisters filled with compost and an open unit with a long bed of compost. The vault unit is typically used in situations where space is limited, and the open unit is typically used to treat high volume runoff. Consult the water quality menus in Section 6.1 (p. 6-3) for specific information on how a LCF can be used to meet Core Requirement # 8. 6.5.5.1 METHODS OF ANALYSIS 6.5_5.2 Compost filter sizing is based on the water quality design flow (see Section 6.2.1, p. 6-17). Since the process and the compost are patented, Stonnwater TM Management personnel will configure a leaf compost filter based on the design flow provided and specific site characteristics. In King County, the WQ design flow should be based on the KCRTS modeled flows, described in Chapter 3, rather than on other flow-estimation methods. An accurate description of land use and potential sediment and pollutant loading sources shall also be provided to Stonnwater TM Management personnel, who consider these factors in sizing. The typical size of the drop-in unit can be estimated based on the water quality design flow in Table 6.5.5.A (below).

If used in another situation, an approved adjustment is required (see Section 1.4). Providing adequate pretreatment and performance monitoring are key to obtaining an adjustment approval. See Section 6.5.1, p. 6-99 for general pretreatment requirements. Access Requirements I. Unobstructed access must be provided over the entire compost filter bed by either access doors or removable panels to allow for removal and replacement of the bed. Removable panels, if used, shall be at grade, have stainless steel lifting eyes, and weight no more than 5 tons per paneL 2. Access to the inflow and outlet cells must also be provided. 3. Ladder access is required when vault height exceeds 4 feet. 4. Locking lids shall be provided as specified for detention (see Section 5.3.3). Access Roads, Right of Way, and Setbacks Same as for detention vaults (see Section 5.3.3). Construction Considerations Installalion of a leaf compost filter shall follow the manufacturer's recommended procedures. Maintenance Requirements Maintenance needs vary from site to site based on the type of land use activity, implementation of source controls, and weather conditions. Leaf compost filters shall be inspected quarterly or at a frequency recommended by the supplier. Inspection and maintenance shall include the following: I. The operation and maintenance instructions from the manufacturer shall be kept along with an inspection and maintenance log. The maintenance log shall be available for review by County inspectors. 2. Routine maintenance shall include inspecting for debris, vegetation, and sediment accumulation, flushing the underdrain, and removing or replacing compost media. 3. Sediment shall be removed when the accumulation causes the infiltration capacity to drop below the design flow rate of 2 to 2.2 gpmlsf. Note: Instructions are available from the manufaCTurer for testing infiltration capacity. 4. The compost media should be replaced at least once a year or when infiltration capacity is unrecoverable. Sediment removal andlor compost media replacement may require a vactor truck. 5. Media shall be disposed of in accordance with applicable regulations, including the Seattle-King County Department of Public Health solid waste regulations (Title 10) and state dangerous waste regulations (WAC 173-303). In most cases, compost media may be disposed of as solid waste. 1998 Surface Water Design Manual 6-132 6 GENERAL NOTES STORMr-ILTER" DATA 1-) STOONFlL1ER BY ST<JI:MWATIR M.t.NA.(J9.I£NT. PCRll..AND.

HISTORYIBACKGROUND: The Subdivision Technical Conunittee (STC) of King County has conducted an on-site examination of the subject property. The STC has discussed the proposed development with the applicant to clarify technical details of the application, and to determine the compatibility of this project with applicable King County plans, codes, and other official documents regulating this development. As a result of preliminary discussions, the applicant presented the Technical Conunittee with a revised plat on February 26, 2004. The primary modifications include: • Accurate delineation of the on-site wetlands • Minor rearrangements of lots • Provision of a larger drainage and water quality facility D. THRESHOLD DETERMINATION OF ENVIRONMENTAL SIGNIFICANCE: Pursuant to the State Environmental Policy Act (SEPA), RCW 43.2IC, the responsible official of the LUSD issued a mitigated threshold determination of non-significance (MONS) for the proposed development on March 15,2004. This determination was based on the review of the environmental checklist and other pertinent documents, resulting in the conclusion that the proposal would not cause probable significant adverse impacts on the environment provided the following measures are complied with: 1. A four100t tall fence shall be constructed along the edge of the sensitive Area Tracts B and C. The fence shall follow the common boundaries of the wetland tracts and the adjoining lots and road. 2. Fencing details, construction and location shall be shown on the engineering plans for DDES review and approval. This mitigation is intended to reduce disturbance within the protective buffer and associated wetland. 3. All existing structures and other derbies shall be removed from the sensitive area tracts and the area shall be restored in accordance with KCC 21A.24. Agencies, affected Native American tribes and the public were offered the opportunity to conunent on or appeal the determination for 21 days. Neither the MDNS nor the specific mitigation measures were appealed by any party, including the applicant, and they have been incorporated as part of the applicant's proposal. , E.

METRO: No response. L02P0012, Petro Vista Staff rpt. - 2 - F. NATURAL ENVIRONMENT: I. Topography: The site slopes down moderately from southwest to northeast. The maximum slope is less than 20%. 2. Soils: One surface soil is found on this site per King County Soil Survey, 1973. the entire site is classified AgB Agl! _ Alderwood gravely, sandy loam; 0-6% slopes. Runoff is slow and the erosion hazard is slight. This soil type has a moderate limitation for low building foundations due to a seasonally high water table, and severe limitations for septic tank filter fields due to very slow permeability in the substratum. 3. Wetland/streams: Two wetland reports were prepared by Wiltermood Associates, Inc. and LeRoy Surveyors & Engineers, Inc. The King County Wetland Ecologist reviewed the reports and conducted a field visit. Two wetland areas were identified on the site. The area in the north central portion of the site is classified as a Class II wetland. The area near the east property line of the site and extending east outside of the site is classified as a Class I wetland. There is a Class 2S stream a few feet east of the site. The site lies within the Soos Creek drainage basin. 4. Vegetation: This site is moderately covered by second-story vegetation and groundcover consists of Northwest native species. 5. Wildlife: Small birds and animals may inhabit this site; however, their population and species are limited due to nearby development. No threatened or endangered species are known to exist on or near the property. . 6. Mapped Sensitive Areas: The Sensitive Areas Map Folio indicates that the Soos Creek Inventoried Wetland 5402 is located a few miles east of the site. An off site Class II fish bearing stream also runs east of the site. G. NEIGHBORHOOD CHARACTERISTICS: The property lies within a rapidly developing neighborhood south of SE Petrovisky Road and east of Benson Highway. The site abuts I 18 th Avenue SE and SE Petrovisky Road to the west and north respectively. A 25-foot wide Bonneville Power Administration transmission line easement runs east of the site. There are residential parcels directly south of the site developed with residential structures. The site itself is developed with an office and storage buildings which will all be removed. The site and the surrounding parcels to the west, south and east are zoned R -6. The area north of SE Petrovisky Road is zoned R-18. H. SUBDIVISION DESIGN FEATURES: I. Lot Pattern and Density: The proposed lot and street layout is in conformance with the King County Subdivision and Zoning Codes 2. Internal Circulation: All the lots within the subdivision except Lot 23 wiJI have access to IISth Avenue SE via a subaccess road (SE I 76th Court) which wiJI be constructed as part of this subdivision. Lot 23 will have direct access to SE 11S th Avenue SE. SE I 76th Court will extend east from IlSth Avenue SE at mid width of the site and terminate in a cul-de-sac near the east end of the site. 3. Roadway Section: The interior road and the site's frontage with I 16th Avenue SE will be improved to urban road standards consisting of curb, gutter and sidewalks. 4. Drainage: The proposed development site contains two primary drainage SUbbasins. The east portion of the property drains to an offsite wetland and stream corridor which comprises portions of the headwater for Soos Creek. The western portion of the site drains to an onsite wetland located within proposed Tract B as shown on the site plan. As described in the applicant's preliminary drainage analysis, the onsite wetland functions as a closed depression which captures surface water within the project and L02P0012, Petro Vista Staff rpt. -3 - also collects drainage from offsite areas located south of the property. The closed depression has some capacity to detain and infiltrate water, however, during major storm events the wetland fills up and overtops into the right-of-way for Petrovitsky Road. Based upon the applicant's discussion with. property owners living south of the project, the drainage from the closed depression also backs up across the south property line. To assure that site development will provide adequate controls for surface water, the applicant is proposing a storm water detention facility located adjacent to the onsite wetland. This facility will collect and detain the majority of onsite storm water before discharge from the site. An outlet from the facility will be provided to convey storm water to the existing pipe system along Petrovitsky Road, which discharges surface water to the wetland and stream corridor located east of the site. To reduce the existing flooding condition of the onsite wetland, a small amount of runoff will be conveyed to the wetland to provide surface water to support wetland hydrology without causing flooding of surrounding property. As shown on the preliminary site plan, a drainage interceptor will be provided along the south property line to collect offsite storm water for safe conveyance to the wetland. The larger volumes of storm water caused by site development will be collected into the storm water facility before discharge to the downstream system east of the site, rather than discharge to the onsite closed depression. During King County evaluation of downstream drainage conditions, a bog wetland was identified as part of the Soos Creek stream corridor. For site development which drains to an identified bog, the King County drainage manual requires that special water quality facilities must be provided to treat storm water prior to discharge from the site. To accomplish the water quality designs, the applicant's drainage plan shows a combination sand filter and compost filter adjacent to a storm water detention vault. Detailed designs for these facilities will be provided during final review when the applicant submits construction plans for site development. After the construction and inspection process, King County will ultimately own and maintain the drainage and water quality facilities. 5. Other Design Features: The proposal includes a combined recreation and storm facility tract. The storm facility tract will include a water quality feature per the KCSWDM. The storm detention and water quality facility will be constructed underground. The recreation ·improvement will be placed above the drainage facility. 1. TRANSPORTATION PLANS: I. Transportation Plans: The King County Transportation Plan indicates that SE Petrovisky Road is designated as a principal arterial and I 18 th Avenue SE as a neighborhood collector. The subject subdivision is not in conflict with this plan. 2. Subdivision Access: The subdivision will have access to SE Petrovisky Road a principle, arterial via 118 th Avenue SE immediately west of the site. 3. . Traffic Generation: It is expected that approximately 230 vehicle trips per day will be generated with full development of the proposed subdivision. This calculation includes service vehicles (i.e., mail delivery, garbage pick-up, school bus) which may currently serve this neighborhood, as well as work trips, shopping, etc. 4. Adequacy of Arterial Roads: This proposal has been reviewed under the criteria in King County Code 14.70, Transportation Concurrency Management; 14.80, Intersection Standards; and King County Code 14.75; Mitigation Payment System. a. King County Code 14.70 -Transportation Concurrency Management: The Transportation Certificate of Concurrency (#01386) dated March 27, 2002 indicates that transportation improvements or strategies will be in place at the time of development, or that a financial commitment is in place to complete the improvements or strategies within six (6) years, according to RCW 36.70A.070(6). L02P0012, Petro Vista Staff rpt. -4- b.· King County Code 14.80 -Intersection Standards: The traffic gen~rated by this subdivision falls below the threshold requiring mitigation. The eXlstmg artenal system will accommodate the increased traffic volume generated by this proposal. c. King County Code 14.75 -Mitigation Payment System: King County Code 14.75, Mitigation Payment System (MPS), re~~ires ~e payment of a traffic impact mitigation fee (MPS fee) and an admimstr~tlOn fee for each single family residential lot or unit created. MPS fees are deterrnmed by the zone in which the site is located. This site is in Zone(s) 342 per the MPS/Quartersection list. MPS fees may be paid at the time of final plat recording, or deferred until building permits are issued. The amount of the fee will be determined by the applicable fee ordinance at the time the fee is collected. 1. PUBLIC SERVICES: 1. Schools: This proposal has been reviewed under RCW 58.17.110 and King County Code 21A.28 (School Adequacy). a. School Facilities: The subject subdivision will be served by Benson Hill Elementary, Nelsen Junior High, and Lindbergh Senior High Schools, all located within the Renton School District. b. School Capacity: The Renton School Board has adopted capacity figures which indicate their ability to accommodate additional students. c. School Impact Fees: Ordinance 14525 requires that an impact fee per lot be imposed to fund school system improvements to serve new development within this district. Payment of this fee (in a manner consistent withKCC 21A.43 will be a condition of subdi vision approval. d. School Access: The Renton School District has indicated that the future students from this subdivision will walk to all schools. The District has a policy to provide bus service to elementary school children if they live more than one mile from the school. The bus service for junior high and senior high school students is provided for residents living more than 1.5 and 2 miles from such schools respectively. Walkway conditions to the elementary school and the junior high school are substandard. There are sidewalks along the south side of SE Petrovisky Road from the site to 1 16th Avenue SEand an average 2-foot wide paved shoulder along I I 6th Avenue SE to the elementary school site. 2. Parks and Recreation Space: The nearest public park is Soos Creek Trail Park located a few miles east of the site. KCC 2lA.l4 requires subdivisions in the UR and R zone classifications to either provide on-site recreation space or pay a fee to the King County Parks Division for establishment and maintenance of neighborhood parks. At this time, the applicant is proposing to provide a recreation tract which will be combined with the drainage facility tract. KCC 2lA.l4.l90 requires subdivisions to provide tot/children play areas within the recreation space on-site. The applicant proposes to construct the drainage facility under ground and create a recreation space above it. 3. Fire Protection: The Certificate of Water Availability from Soos Creek Water and Sewer District indicates that water is presently available to the site in sufficient quantity to satisfy King County Fire Flow Standards. Prior to final recording of the plat, the water service facilities must be reviewed and approved per King County Fire Flow Standards. K. UTILITIES: I. Sewage Disposal: The applicant proposes to serve the subject subdivision by means of a public sewer system managed by Soos Creek Water & Sewer District. A Certificate of L02P0012, Petro Vista Staff rpt. -5- Sewer Availability, dated May 8, 2002 indicates tbis sewer district's capability to serve the proposed development. 2. Water Supply: The applicant proposes to serve the subject subdivision with a public water supply and distribution system managed by Soos Creek Water and Sewer District. A Certificate of Water Availability, dated May 8, 2002 indicates this district's capability to serve the proposed development. L. COMPREHENSNE AND COMMUNITY PLAN: 1. Comprehensive Plan: This proposal is governed by the 1994 King County Comprehensive Plan which designates this area as Urban. The proposed subdivision is not in conflict with the policies of the Comprehensive Plan. 2. Special Overlay District: The proposed site is subject to the tree retention requirement. The majority of the significant trees are located within the sensitive area tracts. The applicant states that the number of significant trees within the sensitive area tracts are more than 30 percent of all the significant trees on site, thus meeting the requirement for the significant tree retention. M. STATUTES/CODES: If approved with the recommended conditions in this report, the proposed development will comply with the requirements of the County and State Platting Codes and Statutes, and the lots in the proposed subdivision will comply with the minimum dimensional requirements of the zone district. N. ANALYSIS: The Subdivision Technical Committee (STC) has not identified any significant issues involved in the preliminary review and recommendations of this proposal. The STC recognizes that there are substandard walkway facilities from the site to the Benson Hill Elementary school if the children use 118 th Avenue SE. There are no sidewalks or walkways along this road. However, the elementary students from this area could use the sidewalk on the south side ofSE Petrovitsky Road and the 2 -to-3-foot paved shoulder along I 16th Avenue SE to reach the school site. The subjec:;t site appears to be more that one mile from Benson Elementary school. It would be appropriate that the elementary school children be bussed from the site to the school since they have to cross 116th Avenue SE, which is a busy street. O. CONCLUSIONS: The subject subdivision will comply with the goals and objectives of the King County Comprehensive Plan and will comply with the requirements of the Subdivision and Zoning Codes and other official land use controls of King County, based on the conditions for final plat approval. P. RECOMMENDATIONS: It is recommended that the subject subdivision, revised and received February 26, 2004 be granted preliminary approval subject to the following conditions of final approval: 1. Compliance with all platting provisions of Title 19 of the King County Code. 2. All persons having an ownership interest in the subject property shall sign on the face of the final plat a dedication that includes the language set forth in King County Council Motion No. 5952. L02P0012, Petro Vista Staff rpt. - 6 - 3. The plat shall comply with the base density (and minimwn density) requirements of the R-6 SO zone classification. All lots shall meet the minimum dimensional requirements . of the R-6 zone classification or shall be as shown on the face of the approved preliminary plat, whichever is larger, except that minor revisions to the plat which do not result in substantial changes may be approved at the discretion of the Department of Development and Environmental Services. 4. All construction and upgrading of public and private roads shall be done in accordance with the King County Road Standards established and adopted by Ordinance No. 11187, as amended (1993 KCRS). 5. The applicant must obtain the approval of the King County Fire Protection Engineer for the adequacy of the fire hydrant, water main, and fire flow standards of Chapter 17.08 of the King County Code. 6. Final plat approval shall require full compliance with the drainage provisions set forth in King County Code 9.04. Compliance may result in reducing the number and/or location of lots as shown on the preliminary approved plat. Preliminary review has identified the following conditions of approval which represent portions of the drainage requirements. All other applicable requirements in KCC 9.04 and the Surface Water Design Manual (SWDM) must also be satisfied during engineering and final review. a. Drainage plans and analysis shall comply with the 1998 King County Surface Water Design Manual and applicable updates adopted by King County. DDES approval of the drainage and roadway plans is required prior to any construction. b. Current standard plan notes and ESC notes, as established by DDES Engineering Review, shall be shown on the engineering plans. c. The following note shall be shown on the final recorded plat: All building downspouts, footing drains, and drains from all impervious surfaces such as patios and driveways shall be connected to the permanent storm drain outlet as shown on the approved construction drawings # on file with DDES and/or the King County Department of Transportation. This plan shall be submitted with the application of any building permit. All connections of the drains must be constructed and approved prior to the final building inspection approval. For those lots that are designated for individual lot infiltration systems, the systems shall be constructed at the time of the building permit and shall comply with plans on file." d. Storm water facilities shall be designed using the KCRTS Level One Flow Control standard. Water quality facilities shall also be provided using the Sphagnum bog protection menu. As shown on the conceptual drainage plan, the outlet of the detention pond and water quality facility will connect to the existing conveyance system along Petrovitsky Road and small areas ofundetained flows will be used to maintain wetland hydrology within Tract B. Based upon the fmal drainage analysis, the size of the proposed drainage tracts may have to increase to accommodate the required detention storage volumes and water quality facilities. All runoff control facilities shall be located in a separate tract and dedicated to King County unless portions of the drainage tract are used for recreation space in accordance with KCC 21 A.14.1S0. e. The final drainage analysis shall evaluate the requirements for off-site bypass as outlined in the drainage manual on page 1-36. As noted in the design criteria, the contribution of flows to an onsite wetland must be maintained and the natural attenuation of flows under pre-developed conditions must also remain. The design engineer shall evaluate all areas which may contribute offsite flows including the ditch along IIS th Avenue SE. As noted in the applicants Level One Offsite analysis dated May 15,2003, during major storm events the onsite wetland fills up and overtops to Petrovitsky Road and also backs up water across the south property line. The design engineer shall evaluate any potential flooding issues and provide drainage designs which adequately prevent potential drainage L02P0012, Petro Vista Staff rpt. -7- problems. As shown on the preliminary plat, an interceptor swale is proposed along the south property line of lots 10 and II. f. The final drainage plans and technical reports shall evaluate all applicable design criteria for onsite closed depressions and ponding areas as discussed in the drainage manual on page 3-54. The existing wetland in Tract B currently captures surface water from off site areas and the western portion of the project area which may influence the storm water modeling for pre and post developed flow rates and volumes. During final engineering review, King County will review and determine how much off site flow andlor undetained project areas may drain to the wetland in Tract B without pretreatment in detention or water quality facilities. g. The final engineering plans and recorded plat shall show the 100-year floodplain boundaries as required by Special Requirements No.2 in the drainage manual. S. The proposed subdivision shall comply with the 1993 King County Road Standards (KCRS) including the following requirements: a. Southeast I 76th Court shall be improved as an urban subaccess street. b. One hundred eighteen (1ISth) Avenue Southeast shall be improved as an urban neighborhood collector along the frontage of the subject property. As noted in KCRS 2.03, for neighborhood collector streets intersecting with an arterial (SE Petrovitsky), the width must be 36-feet wide for the first 150 feet. A 25-foot right-of-way line radius is also required as shown in KCRS 2.10. c. One hundred eighteen (II 8th ) Avenue SE is designated a neighborhood collector street which may require designs for bus zones and turn outs. As specified in KCRS 2.16, the applicant or his engineering consultant shall contact Metro and the local school district to determine specific requirements. e. Street illumination shall be provided at intersections with arterials in accordance with KCRS 5.05. f. Modifications to the above road conditions may be considered by King County pursuant to the variance procedures in KCRS 1.08. 9. During preliminary site inspections, King County has identified fill material, building debris, and a concrete foundation within the site. To address the required site grading and designs for development, the applicant shall submit a geotechnical report with the engineering plans to address all applicable earthwork, site preparation, road construction, and utility installation. The geotechnical engineer shall also evaluate the soil conditions and requirements for the proposed storm water vault located within Tract A. Structural plans and calculations for the vault must be prepared by a licensed structural engineer. 10. All utilities within proposed rights-of-way must be included within a franchise approved by the King County Council prior to final plat recording. II. King County Code 16.S2.150D requires seasonal limitations for construction within the Soos Creek basin. During the period October I through March 31, clearing and grading is not allowed unless certain provisions are complied with as outlined in the code. The applicants engineering plans shall demonstrate compliance with the applicable code requirements and provide notes referencing the seasonal limitations set forth in KCC l6.S2.150D. 12. The applicant or subsequent owner shall comply with King County Code 14.75, Mitigation Payment System (MPS), by paying the required MPS fee and administration fee as determined by the applicable fee ordinance. The applicant has the option to either: (l) pay the MPS fee at final plat recording, or (2) pay the MPS fee at the time of building permit issuance. If the first option is chosen, the fee paid shall be the fee in effect at the time of plat application and a note shall be placed on the face ofthe plat that reads, "All fees required by King County Code 14.75, Mitigation Payment System (MPS), have been L02P0012, Petro Vista Staff rpt. -S - paid." If the second option is chosen, the fee paid shall be the amount in effect as of the date of building pennit application. 13. Lots within this subdivision are subject to King County Code 2IA.43, which imposes impact fees to fund school system improvements needed to serve new development. As a condition offmal approval, fifty percent (50%) of the impact fees due for the plat shall be assessed and collected immediately prior to recording, using the fee schedules in effect when the plat receives final approval. The balance of the assessed fee shall be allocated evenly to the dwelling units in the plat and shall be collected prior to building permit issuance. 14. There shall be no direct vehicular access to or from 118 th A venue SE from those lots which abut it except lot 23. A note to this effect shall appear on the engineering plans and final plat. 15. The proposed subdivision shall comply with the Sensitive Areas Code as outlined in KCC 2IA.24. Pennanent survey marking, and signs as specified in KCC 21A.24.l60 shall also be addressed prior to fmal plat approval. Temporary marking of sensitive areas and their buffers (e.g., with bright orange construction fencing) shall be placed on the site and shall remain in place until all construction activities are completed. Preliminary plat review has identified the following specific requirements which apply to this project. All other applicable requirements from KCC 21A.24 shall also be addressed by the applicant. a. . The Class I wetland near the east property line shall have a minimum buffer of 100 feet, measured from the wetland edge. b. the Class 2 wetland near the north boundary ofthe site shall have a minimum buffer of 50 feet, measured from the wetland edge. c. The Class 2S stream shall have a minimumlOO-foot buffer, measured from the ordinary high water mark (OHWM). d. The stream, wetlands and their respective buffers shall be placed in a Sensitive Area Tract (SAT). e. A minimum building setback line of 15 feet shall be required from the edge of the tract. f. Buffer width averaging may be allowed by King County if it will provide . additional protection to the wetland/stream or enhance there functions, as long as the total area contained in the buffer on the development proposal site does not decrease. In no area shall the buffer be less than 65 percent of the required minimum distance. To ensure such functions are enhanced a mitigation plan will be required for the remaining on-site sensitive areas. An enhancement plan shall be submitted for review during engineering review. g. A mitigation plan and fmancial guarantee/bond will be required for any proposed impacts of sensitive areas including buffers. The bond amount will include all components of the mitigation plan including, but not limited to, plantings, grading, fencing, signs, inspections, and monitoring for five years. h. Prior to commencing construction activities on the site, the applicant shall temporarily mark sensitive areas Tract(s) in a highly visible manner, and these areas must remain so marked until all development proposal activities in the vicinity of the sensitive areas are completed. i.

Detention out-fall structures maybe permitted within the wetland/stream buffers. however, structures shall be located in the outer edge of the buffer, if possible. All buffer impacts shall be mitigated. I. Development authorized by this approval may require other state and/or federal permits or approvals. It is the applicant's responsibility to correspond with these agencies prior to beginning work on the site. m. The following have been established by SEPA as necessary requirements to mitigate the adverse environmental impacts of this development. The applicants shall demonstrate compliance with these items prior to final approval. I) A four-foot tall fence shall be constructed along the edge of the sensitive Area Tracts B and C. The fence shall follow the common boundaries of the wetland tracts and the adjoining lots and road. Fencing details, construction and location shall be shown on the engineering plans for DDES review and approval. This mitigation is intended to reduce disturbance within the protective buffer and associated wetland. 2) All existing structures and other derbies shall be removed from the sensitive area tracts and the area shall be restored in accordance with KCC 21A..24. n. The following note shall be shown on the final engineering plan and recorded plat: RESTRICTIONS FOR SENSITIVE AREA TRACTS AND SENSITIVE AREAS AND BUFFERS Dedication of a sensitive area tract/sensitive area and buffer conveys to the public a beneficial interest in the land within the tract/sensitive area and buffer. This interest includes the preservation of native vegetation for all purposes that benefit the public health, safety and welfare, including control of surface water and erosion, maintenance of slope stability, and protection of plant and animal habitat. The sensitive area tract/sensitive area and buffer imposes upon all present and future owners and occupiers of the land subject to the tract/sensitive area and buffer the obligation, enforceable on behalf of the public by King County, to leave undisturbed all trees and other vegetation within the tract/sensitive area and buffer. The vegetation within the tract/sensitive area and buffer may not be cut, pruned, covered by fill, removed or damaged without approval in writing from the King County Department of Development and Environmental Services or its successor agency, unless otherwise provided by law. The common boundary between the tract/sensitive area and buffer and the area of development activity must be marked or otherwise flagged to the satisfaction of King County prior to any clearing, grading, building construction or other development activity on a lot subject to the sensitive area tract/sensitive area and buffer. The required marking or flagging shall remain in place until all development proposal activities in the vicinity of the sensitive area are completed. No building foundations are allowed beyond the required 15-foot building setback line, unless otherwise provided by law. 16. The proposal is to combine the recreation and drainage tracts.

The project proposes 23 single-family attached/detached housing units. The site is located at the southeast corner of 118'h Ave. S.E. and S.E. Petrovitsky Rd. (S.E. 176'h St.) in unincorporated King County. Access to the site would be via a new road onto 118'h Ave. Southeast. We have visited the project site and surrounding road network, and have prepared this study per the King County Intersection Standards requirements as implemented by Ordinance #11617, which requires analysis of intersections that carry 30 or more site generated trips and at least 20 percent of the site generated traffic. However, the proposed 23 single-family unit project would not generate more than 30 PM peak hgur trjDs. The project has received Certificate 01 I ransportation Concurrency No. 01386 from the County, a copy of which is attached. The summary, conclusions and recommendations begin on page 7 of this report. PROJECT DESCRIPTION Figure 1 is a vicinity map showing the location of the site and the surrounding road network. The site is located at the southeast corner of 118'h Ave. S.E. and S. E. Petrovitsky Rd. (S.E. 176'h St.). Figure 2 shows a preliminary site plan and on-site roadway circulation. The project proposes 23 single-family attached/detached housing units. Access to the site would be via a new local access road onto 118'h Ave. Southeast. Full development of the project is expected to occur by the end of 2004, however to ensure a conservative analysis 2005 is used as the horizon year for the purposes of this study. EXISTING PHYSICAL CONDITIONS Project Site The project site is presently undeveloped. G:\-Projeds Fo/derV<04 ProjectsIX0431002 Petro Vista TlAooc Mr. Dale Van Derschelden January 14, 2003 Page -2- Street Facilities Figure 3 shows existing traffic control, numter of road lanes, number of approach lanes at intersections, and other pertinent information. The primary roads within the study area and their functional classifications, per the King County Arterial Functional Classification Map, December 1995, are as follows: SR 515 (10S'h Ave. S.E.) S.E. 176'h St.lPetrovitsky Rd. 116'h Ave. S.E. 11S'h Ave. S.E. S.E. 1S0'h St. State Highway (Principal Arterial) Principal Arterial Minor Arterial Local Access Local Access Petrovitsky Rd. is a four to five lane arterial with a two way left turn lane (TWL TL) on portions'bf tills roadway. I here IS a i we i e on PetnR<itsk Rd. a . 'h Southeast. The posted spee Iml IS 1PH. There is curb, gutter and sidewalk on both sides of the roadway. Transit Facilities Metro Transit System provides transit service in King County. Their online web site, at http://transit.metrokc.gov/, indicates that routes 101 and 155 o~erate along Petroyjtsky Rd. near the project site. The closest bus stop would be located at 116' Ave. Southeast. Copies of the time schedules for these routes can be found on Metro's web site. Pedestrian and Bicycle Facilities The proposed project is located in an suburban environment, and within walking and cycling distance of shopping and social opportunities. Pedestrian sidewalks exist on both sides of Petrovitsky Rd. adjacent to the project site. There are no sidewalks on 11S'h Ave. S.E., which is a local access road. EXISTING TRAFFIC CONDITIONS Traffic Volumes Figure 4 shows the existing PM peak hour tuming movement traffic volumes at the 11S'h Ave. S.E./Petrovitsky Rd. intersection. The traffic counting firm Trafficount performed the turning movement traffic volume count on Tuesday, December 10, 2002. Level of Service Analysis Level of service (LOS) is a qualitative measure describing operational conditions within a traffic flow, and the perception of these conditions by drivers or passengers. These conditions include factors such as speed, delay, travel time, freedom to maneuver, traffic interruptions, comfort, convenience, and safety. Levels of service are given letter deSignations, from A to F, C:\-ProjeC1S Folder\K04 Projecls\K04J1002 Petro Visla TIA.doc Mr. Dale Van Derschelden January 14, 2003 Page -3- with LOS A representing the best operating conditions (free flow, little delay) and LOS F the worst (congestion, long delays). Generally, LOS A and B are high, LOS C and D are moderate, and LOS E and F are low. Table 1 shows the calculated LOS for existing PM peak hour conditions at the analysis intersection. The LOS were calculated using the procedures in the Transportation Research Board Highway Capacity Manual 2000 Edition. At intersections, LOS is determined by the calculated average delay per vehicle. The LOS and corresponding average delay in seconds are as follows: I TYPE OF I A I B I INTERSECTION C I D I E I F I Signalized ::10 > 10 and <20 > 20 and:: 35 > 35 and:: 55 > 55 and:: 80 > 80 Stop Sign ::10 > 10 and::: 15 > 15 and:: 25 > 25 and:: 35 > 35 and::: 50 > 50 Controlled The results of our analysis show that the analysis intersection is currently operating at LOS C for the northbound approach during the PM peak hour. This is the worst movement for the intersection. The LOS data sheet is attached. Accident Data King County provided accident summary data for the time period from January 1, 1999 to December 31, 2001 for the analysis intersection. A copy of the accident data is attached. The following table summarizes the accident data provided. This table also shows the average accident rate per million entering vehicles. TRAFFIC ACCIDENT HISTORY NO. OF ACCIDENTS TOTAL ACCIDENTS INTERSECTION ACCIDENTS PER 1999 2000 2001 (1999-2001) MEV" Petrovitsky Rd.l 1 1 4 6 0.26 1181h Ave. S.E. Notes: * Accidents per million entering vehicles (based on the average accident rate per year, for (1999-2001). King County's Accident Rates for Arterial Roadways does not contain data on average accident rates per million entering vehicles at intersections. However, based on our experience, C:\~Projects Folder\K04 Projecls\K0431002 Petro Vista TIA,doc Mr. Dale Van Derschelden January 14, 2003 Page -4- an accident rate of less than one is generally considered to indicate that an intersection is operating satisfactorily, one to two is typical, and over two requires further review. Based on the accident rate calculated and our field review no apparent accident problem exists at the analysis intersection. Sight Distances Per the County's request we conducted a sinh! distance analysis at 11gth °'(8. S.E. onto Petrovitsky Road. Our sight distance measuremeMs were taken on December 18, 2002. Results of the available stopping sight distance (SSD) and entering sight distance (ESD) measurements at the existing road onto Petrovitsky Rd. are shown in the following table: SIGHT DISTANCE SUMMARY Proposed Site Access To/From the To/From the King County West East Design Criteria Stopping Sight Distance (ft.) 500 Over 750 400 (440*) Entering Sight Distance (ft.) C 580.J Over 750 620 Notes: * Adjusted for the eastbound SSD (from the west) to account for the approx. 6% downgrade. This table also shows the County's SSD and ESD criteria per Table 2.1 in the King County Road Standards -1993 (KCRS). The KCRS recommended sight distances are for a design speed of 45 MPH (posted speed limit on Petrovitsky Rd. of 35 MPH plus 10 MPH per the County policy). Our field measurements show that the County's SSD criteria of 400 (440*) feet is met both to the east and west for the existin3 intersection. T e Count's ESD criteria of 620 feet is also met to the east. Looking to the west the ESD of 580 feet is limited ue 0 t e cres vertical curve where the Sl n' 116'h Ave. S.E./Petrovitsky Rd. intersection is 10cated."The 580 ft.

The distance is approximately 630 feet from the centerline of 1181h Ave. S.E. intersection to the centerline of 116'h Ave. Southeast. We do not recommend any corrective measures to improve the ESD to the west since the 1181h Ave. S.E./Petrovitsk Rd. intersection is an existin Cou 'nterse i . t dist y ac Ing y ap roximatel 40 feet The cost of lowering the crest curve on e rovitsky , IS cos 0 I live or t IS small plat project. Furthermore, the accident histo'}' does not show that there is an unsafe condition at this intersection. • I FUTURE TRAFFIC CONDITIONS WITHOUT THE PROJECT Traffic Volumes Figure 5 shows projected year 2005 PM peak hour traffic volumes without the project. C:\-Projecls Folder\K04 ProjeclslK0431002 Petro Vista TIA.doc: Mr. Dale Van Derschelden January 14, 2003 Page -5- These volumes include the existing traffic volume counts plus a compounded 2% annual growth rate to account for background growth. This 2% annual growth rate is based on our calculations for similar traffic studies done previously in the vicinity of the project site. Level of Service Table 1 shows the calculated LOS for 2005 without-project conditions at the analysis intersection. The LOS would remain unchanged from existing conditions, with a small increase in delay per vehicle, for the projected 2005 PM peak hour traffic volumes. TRIP GENERA TlON AND DISTRIBUTION A vehicle trip is defined as a single or one direction vehicle movement with either the origin or destination (exiting or entering) inside the proposed development. Trip Generation The proposed project is expected to generate the vehicular trips during an average weekday and during the street traffic peak hours as shown below: Time Period Trip Generation Rate Trips Trips Exiting Total Entering Weekday T = 9.57(X) 110(50%) 110 (50%) 220 AM Peak Hour T = 0.75(X) 4 (25%) 13 (75%) 17 PM Peak Hour T=1.01(X) 15 (64%) 8 (36%) @ Where: T = Trips Generated X " Number of Dwelling Units (= 23) The trip generation is calculated using the average trip rates in the Institute of Transportation Engineers (ITE) Trip Generation, Sixth Edition, for Single-Family Dwelling (ITE Land Use Code 210). These trip generation values account for all site trips made by all vehicles for all purposes, including resident, visitor, and service and delivery vehicle trips. Trip Distribution Figure 6 shows the calculated site-generated PM peak hour traffic volumes and the projected trip distribution. The project's trip distribution is based on the characteristics of the road network, existing traffic volume pattems, the location of likely trip origins and destinations (employment, shopping, social and recreational opportunities), and expected travel times. The project's trip distribution is also based on our c.ther projects in the vicinity of the Petro Vista site. C:\-Projects Folder\K04 ProjectslK0431002 Petro Vista TIA.doc Mr. Dale Van Derschelden January 14, 2003 Page - 6 - FUTURE TRAFFIC CONDITIONS WITH PROJECT Traffic Volumes Figure 7 shows the projected 2005 PM peak hour traffic volumes with the proposed project. The project-generated PM peak hour traffic volumes, shown on Figure 6, were added to the projected 2005 background traffic volumes shown on Figure 5 to obtain the Figure 7 volumes. Level of Service and Queuing Table 1 shows the calculated PM peak hour LOS for 2005 with-project conditions at the analysis intersection. The LOS for the northbound approach would decrease to LOS D, with 31.2 seconds of delay per vehicle. However, the LOS analysis shows that developing the project would not significantly affect the LOS operation at the analysis intersection nor any other surrounding intersections. The LOS worksheets are attached. As requested by the County staff a review of the with-project northbound gueuin£ at the 118'h Ave. S.E./Petrovits . . (shown on th1f COS worksheet) shows that ue to he ow overall volume of vehicles using this road, even durin the PM eak hour the northbound 95 ercentile ueue wo I t most be 0 . . e. ere ore, ere wou no e a problem with the northbound vehicles backing up to the south and blocking the entrance of the proposed plat. TRAFFIC IMPACT MITIGA TION REQUIREMENTS King County requires mitigation fees according to their Mitigation Payment System (MPS). The fees are aSSigned according to the zone that the project is located within. According to the County's Certificate of Transportation Concurrency the Petro Vista project is located in MPS zone #342. The current assigned mitigation fee for a single-family residence in MPS zone 342 is $3,730/unit. Therefore the total MPS fee would be $85,790 for the 23 proposed units. King County Intersection Standards also require mitigation for any intersections " ... that will function at a level of service worse t'1an "E", and that carry thirty (30) or more added vehicles in anyone hour period as a direct impact of the proposed development, and that will be impacted by at least twenty (20) percent of the new traffic generated from the proposed development in the same one hour period;" No intersections would be impacted by more than 30 project-generated peak hour trips or are expected to operate at a LOS worse than E. Therefore, per this criteria, development of the subject project would not cause a significant adverse impact at any intersections. Thus, traffic mitigation should be limited to payment of the MPS fee and access and frontage improvements in accordance with County criteria. C:I-projecls FoIder\K04 Projects\K0431002 Petro Vista TIA.doc Mr. Dale Van Derschelden January 14, 2003 Page -7- SUMMARY, CONCLUSIONS AND RECOMMENDA TIONS The Petro Vista plat is expected to generate a total of 23 PM peak hour trips. To analyze traffic impact at the Petrovitsky Rd.l118'h Ave. S.E. intersection, a level of service analysis was performed for projected future traffic volumes, using the collected traffic data. The evaluation of the traffic impact of the proposed project, included adding project-generated traffic to the future traffic volume projection and calculating the level of service. The forecasted levels of service are acceptable per County criteria. Development of the subject project would not cause a significant adverse impact at any intersections. Therefore, based on our analysis of the proposed project we have the following comments and traffic mitigation measures: 1. Looking to the west from 118'h Ave. S.E. the entering sight distance is limited due to the crest vertical curve where the signalized 116'h Ave. S.E.lPetrovitsky Rd. intersection is located. 2. Since the 118'h Ave. S.E.lPetrovitsky Rd. intersection is already an existing County intersection and the sight distance is only lacking by 40 feet or so, we recommend that this discrepancy be waived. 3. Construct the site access roadway and frontage in accordance with applicable County criteria. 4. Contribute $85,790 for the 23 proposed units to King County's Mitigation Payment System.

Job # 5183 iii - Petrovitsky Road Site Wetland Delineation 1.0 INTRODUCTION 1.1 Purpose The purpose of this investigation was: • to characterize and delineate the offsite wetland on the northeast boundary of the property as an amendment to the previous Petrovitsky Road Site Wetland Report (Prichard, 1999) • to classify the offsite wetland according to King County Code Chapter 21 A.06.1415 and determine required buffer width according to King County Code Chapter 21 A.24.320 • to evaluate existing conditions in the offsite wetland and perform wetland functions assessments • to assess probable impacts to the offsite wetland as a result of the proposed development. 1.2 Location The property is located in Renton, King County, Washington, at the SE corner of S.E. Petrovitsky Road and 118th Avenue S.E. Section 33, Township 23 N, Range 5 E, W.M. The wetland discussed in this report (offsite wetland) is located on the east property boundary extending offsite to the east onto a Bonneville Power Administration (BPA) power line right-of-way (see Figure 1 Site Map Orthophoto, Figure 2 Site Map Survey, and Figure 3 Vicinity Map). 1.3 Project Description The property owners are proposing to develop and subdivide the slightly less than four acre site into 23 single family residential lots. 1.4 Site Description The property consists of King County Parcels 6196600380 and 6196600381. It is bordered to the north by S.E. Petrovitsky Road (S.E. 176th St.), to the west by 118th Ave. S.E., and to the east by a BPA power line right-of- way. There is an office building, a garage, a shed and an equipment yard located on the eastern half of the property. The land slopes down towards the center from the buildings, and the western and southern sides to create a small depression located in the north half of the property. This depression contains a small (approximately 0.12 acre) Class 2 wetland dominated by Scrub-Shrub vegetation with a developing forested class. The property has areas of Himalayan blackberries (Rubus procerus), mixed young forest, and open areas. On the east side of the buildings, the land slopes down to the eastern border. I his hillside IS dominated by black cottonwoods (Populus balsamtfera). I he offsite wetland skirts along the eastern border fOr approximately 200 ft, at which point it veers offsite to the east. The majority of the wetland is located on the BPA power line ri ht-of-way. The wetland is bordered to the south and east by a ransmlsslon Ine access roa ,and to the north by S.E. Petrovitsky Road (S.E. 176th St.) (see Figure 1 Site Map Orthophoto and Figure 2 Site Map Survey) . LeRoy Surveyors and Engineers, Inc.

Data sources reviewed for this delineation included: • King County Wetlands Inventory • King County Sensitive Areas maps • Soil Survey, King County Area, Washington, Sheet Number 11 (USDA, 1973) • King County Code: Environmentally Sensitive Area Ordinances Chapter 21A.24.320; and Technical Terms and Land Use Definitions Chapter 21A.06.1415 2.2 Wetland Identification Wetlands are defined as "those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions" (Washington State Department of Ecology, 1997, and references therein). Wetlands are jurisdictionally identified by the presence of three physical parameters. These parameters include hydrophytic vegetation, hydric soils and hydrology (Washington State Department of Ecology, 1997). Wetland determination was made using "Routine Methodology for Areas Equal to or Less Than 5 Acres in Size" (Washington State Department of Ecology, 1997). This method is based on the 1987 Army Corps of Engineers Manual (Environmental Laboratory, 1987). 2.21 Hydrophytic Vegetation Hydrophytic vegetation is the first parameter required for wetland determination (Washington State Department of Ecology, 1997). Hydrophytic plants are uniquely adapted to cope with the stresses imposed by the soil saturation/inundation and anaerobic conditions which occur in wetlands. Several indicators may be used to determine whether hydrophytic vegetation is present on a site (Washington State Department of Ecology, 1997). The most reliable indicator is when more than 50% of the dominant plant species are ones that are most frequently found in wetlands. The U.S. Fish and Wildlife Service has developed a rating system for plants to indicate the estimated probability of their occurrence in wetlands (see Table 1). The indicator status for plants in the Pacific Northwest is summarized in Reed (1988) and Reed et al. (1993). Vegetation is considered to be hydrophytic when more than 50% of the dominant species are OBL, FACW+, FACW, FACW-, FAC+ or FAC. Dominant plant species were determined by the 50/20 rule as defined in the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology, 1997). "Dominant plants species are those species in each stratum [tree, shrub, vine, herb] that when ranked in descending order of abundance [percent aerial coverage] and cumulatively totaled, immediately LeRoy Surveyors and Engineers, Inc. Job # 5183 5 - Petrovitsky Road Site Wetland Delineation exceed 50 percent of the total dominance measure for that stratum, plus any additional plant species comprising 20 percent or more of the total dominance measure for that stratum." (Washington State Department of Ecology, 1997). Other indicators of hydrophytic vegetation include (in decreasing order of reliability): visual observation of plant species growing in areas of prolonged inundation and/or soil saturation; morphological adaptations to wetland conditions; technical literature references; and physiological and reproductive adaptations to wetland conditions (Washington State Department of Ecology, 1997). Table 1. Plant Indicator Status Categories (Reed 1988). Indicator Category Indicator Definition Symbol Obligate Wetland Plants OBl Plants that almost always occur in wetlands under natural conditions - estimated probability> 99%. Facultative Wetland Plants FACW· Plants that usually occur in wetlands - estimated probability 67%-99%. Facultative Plants FAC· Plants with a similar likelihood of occurring in wetlands or non-wetlands -estimated probability 34%-66%. Facultative Upland Plants FACU· Plants that usually occur in non- wetlands -estimated probability of occurring in wetlands 1 %-33%. Obligate Upland Plants UPl Plants that almost always occur in non-wetlands -estimated probability of occurring in wetlands <1 %. * The three facultative categories are subdivided by (+) and (-) modifiers. For example: FAG+ species have a somewhat greater estimated probability of occurring in wetlands than FAG species, while FAG-species have a somewhat lesser estimated probability (Reed 1988). Plant species were identified using several standard taxonomic references (Cooke, 1997; Guard, 1995; Hitchcock & Cronquist, 1990; Pojar & MacKinnon, 1994). Plants live in relatively homogeneous and predictable assemblages called communities. Plant communities on the site were identified according to a classification system developed by the U.S. Fish and Wildlife Service (Cowardin, et al., 1979). The Cowardin Community Classification System is based on vegetation, hydrology and substrate (soil) characteristics. Two wetland sample plots and one upland sample plot (25 ft. diameter around soil sample pits) were surveyed for the presence of hydrophytic vegetation (see Figure 4 Wetland Map and Data Sheets 1-3). Vegetation was also sampled at regular intervals along, above, and below the wetland boundary for delineation purposes. LeRoy Surveyors and Engineers, Inc. Job # 5183 6 -I Figure 4 Offsite Wetland Map Petrovitsky Road Weiland Rags I V 25' Wetland Buffer e Test Holes () Cu lvert Proposed Lots Proposed Edge of Pa,eme" CJ Wetlands - Petrovitsky Road Site Wetland Delineation 2.22 Hydric Soils The presence of hydric soils is the second parameter required for wetland determination. Hydric soil is defined as " ... a soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part" (Washington State Department of Ecology, 1997). The anaerobic conditions that result from water-logging cause specific, recognizable changes to the soil. Using a tile spade, soil pits (1 ft. diameter) were dug 16 -18 inches deep (wherever possible). Sample pits were dug in the two different wetland vegetative communities (Emergent TH 4 and Scrub-Shrub TH 6) and in an upland site (TH 5) (3 total), and also at regular intervals along, above, and below the wetland boundary for delineation purposes (see Figure 4 Wetland Map). The soil was characterized and examined for hydric indicators immediately below the A horizon, or at 10 inches, whichever was shallower according to the methodology in the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology, 1997) (see Data Sheets 1-3). Hydric soil indicators include (in decreasing order of reliability): deep organic soils (Histosols) such as peats and mucks; Histic epipedons (an 8-16 inch organic layer at or near the surface which is saturated with water for 30 consecutive days); sulfidic material (rotten egg smell); aquic or peraquic moisture regime; reducing soil conditions; and hydric soil colors. Soil colors (hue, value and chroma) were determined using Munsell Soil Color Charts (Munsell Color, 1998). Hue refers to the soil color in relation to red or yellow. Value refers to the lightness of the hue between white (0) and black (10). Chroma refers to the strength of the color, or its departure from the neutral (Munsell Color, 1998; Washington State Department of Ecology, 1997). Munsell colors are recorded as hue value/chroma (e.g. 10YR 4/1). Hydric soil indicator colors include: gleyed soils (greenish or bluish gray); mottled soils with a matrix chroma of 2 or less; and un mottled soils with a matrix chroma of 1 or less (Washington State Department of Ecology, 1997). Mottles are spots or blotches of a different color interspersed within the dominant color (matrix) of a soil layer. They usually result from alternating anaerobic (flooded) and aerobic soil conditions. Soil characteristics were compared to Natural Resource Conservation Service (NRCS) descriptions of mapped soils. 2.23 Hydrology Wetland hydrology, or the presence of water, is the third parameter required for wetland determination (Washington State Department of Ecology, 1997). "The term 'wetland hydrology' encompasses all hydrologic characteristics of areas that are periodically inundated or have soils saturated to the surface for a sufficient duration during the growing season to develop hydric soils and support vegetation typically adapted for life in periodically anaerobic soil conditions" (Washington State Department of Ecology, 1997). To meet wetland hydrology criteria, it is essential to establish that the site in question is periodically inundated or has saturated soils for a sufficient period during the growing season. LeRoy Surveyors and Engineers, Inc. Job # 5183 8 - Petrovitsky Road Site Wetland Delineation Wetland hydrology can be difficult to determine during dry summers. As a result, many of the authorized field indicators are evidence of past or present hydrologic events. Wetland hydrology indicators include (in decreasing order of reliability): recorded data such as stream, lake or tidal gage data, flood predictions and historical data; visual observation of inundation; visual observation of soil saturation; watermarks; driftlines; sediment deposits; drainage patterns within wetlands; oxidized rhizospheres surrounding living roots within the upper 12 inches of soil; local soil survey data; water-stained leaves; the FAC neutral test (comparing numbers of OBL and FACW dominant plant species to numbers of FACU and UPL species); and other indicators according to best professional opinion. The presence of hydrology indicators was determined for the two wetland sample sites and the upland sample site (3 total) (see Figure 4 Wetland Map and Data Sheets 1-3). Hydrology indicators were also examined at regular intervals along, above, and below the wetland boundary for delineation purposes. 2.3 Wetland Delineation and Flagging The wetland boundary was delineated according to the methodology in the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology, 1997) by: • first recognizing obvious wetland and non-wetland areas • then identifying transition zones between the two areas • finally sampling vegetation, soils and hydrology to test for the presence of the three required wetland parameters. Consecutively numbered stakes (WB 31 -52) were positioned along the wetland boundary. The wetland boundary was professionally surveyed by LeRoy Surveyors and Engineers, Inc. in November 1999 (see Figure 1 Site Map Orthophoto, Figure 2 Site Map Survey, and Figure 4 Wetland Map). 2.4 Wetland Functions Assessment The wetland functions were rated using two methods. The first technique used was the Washington State Department of Ecology's Methods for Assessing Wetland Functions (Hruby et al., 1999). This method (WFAP) is based on the Hydrogeomorphic (HGM) Approach for assessing wetland functions which is being developed at a national level by the U.S. Army Corps of Engineers. WFAP uses quantifiable information collected on-site and from references which is then analyzed by a mechanistic model. The result is a scientifically based numeric index of performance for various wetland functions. The second technique used was The Wetland and Buffer Functions Semi-Quantitative Assessment Method (Cooke, 1996) (Modified Reppert Method). This method is based on the Reppert system (Reppert et al., 1979), which was developed by the U.S. Corps of Engineers. Dr. Cooke modified the Reppert System to be more applicable to Pacific Northwest wetlands. The Modified Reppert Method also identifies and rates various potential wetland functions. See the Functional Assessment section in the Results section and the Functional Assessment Data Sheets 4 and 5 in the Appendix for more information. LeRoy SUlVeyors and Engineers, Inc. Job # 5183 9 - Petrovitsky Road Site Wetland Delineation 3.0 RESULTS 3.1 Review of Existing Information 3.11 King County Wetlands Inventory and Sensitive Areas maps The offsite wetland is not listed in the King County Wetlands Inventory, however it is hydrologically connected to a National Wetland Inventory listed wetland. It is also located approximately 500 ft away from Soos Creek Wetland 2 (King County Environmental Division,1990). This wetland is 134 acres with five vegetation classes and is rated as Class 1 (see Figure 5 Vicinity Wetlands Map). 3.12 Soils The soils on the property as well as the offsite wetland are mapped as AgC Alderwood gravelly sandy loam, 6-15% slopes, by the Soil Conservation Service (U.S. Department of Agriculture, 1973). Alderwood soils are the most extensive soils in the survey area, and they are not classified as hydric. However the AgC mapped units can include poorly drained Norma sandy loam and other hydric soils. Alderwood gravelly sandy loam, 6-15% slopes: This soil series is made up of moderately well drained upland soils, which formed under conifers in glacial deposits. The surface layers are very dark brown to dark grayish-brown gravelly sandy loam (10YR 2/2 to 4/3) which extends to an average depth of 12 inches. The subsoil is grayish-brown to brown gravelly sandy loam (2.5Y 5/2 to 7/2) to an average depth of 27 inches. The substratum is grayish-brown consolidated glacial till (2.5Y 5/2). Runoff is slow to medium, and the erosion hazard is moderate (U.S. Department of Agriculture, 1973). Norma sandy loam, 0-2% slopes: This series is made up of poorly drained soils that formed in alluvium, under sedges, grass, conifers and hardwoods. The soils are found in glacial basins and along stream bottoms. The surface layer is black to dark grayish brown sandy loam (1 OYR 211 to 4/2) with up to 15% gravel and extends to an average depth of 10 inches. The subsoil is dark grayish brown to light brownish gray sandy loam (2.5Y 4/2 to 6/2) with up to 35% gravel, which extends to an average depth of 30 inches. The substratum is dark gray to light gray sandy loam (5Y 4/1 to 7/1). Permeability is moderately rapid, runoff is slow, and the erosion hazard is slight. Stream overflow is a severe hazard in places (U.S. Department of Agriculture, 1973). 3.2 On-site Investigation Suzanne Bagshaw visited the site on two days, November 8, 1999 and November 12,1999. On the first visit (11/8/99), the sky was overcast with occasional showers, and the temperature was 58 0 F. Test holes were dug, soil profiled, vegetation sampled, hydrology indicators examined, and the west boundary of the wetland (WB 31-39) was delineated (see Figure 4 wetland Map). On the second visit (11/12/99), it was raining and the temperature was 55 0 F. The remaining wetland boundary (WB 40-52) was delineated on that day. LeRoy Surveyors and Engineers, Inc. Job # 5183 10 - Legend Wetlands o Onst1e Wetland Offsite Weiland Figure 5 Vicinity Wetlands Map King County GIS Wetll, 'nds ~;~~7'~ C 1 Kilometer Buffer "..,.,"'" - Petrovitsky Road Site Wetland Delineation 3.21 Wetland Description The majority 01 the wetland examined is located offsite on a BPA power line right-ol-way, adjacent to the east property boundary. The east side 01 the property angles down to the w' . 00 slo e. This • I Sl e IS omlnated by black cottonwoods (Populus balsamifera). The wetland skirts along the eastern property boundary for approximately 200 ft, at which point it veers offsite to the east. The wetland is bordered to the south and east by a transmission line access road, and to the north by S.E. Petrovitsky Road (S.E. 176th St.). Water flows through the wetland as a small seasonal stream which enters from a culvert on the north ed e and exits throu h a culvert at the s Igure leap op oto, Figure 2 Site ap urvey, and . figure 4 Wetland Map) The outflow from the wetland feeds a small NWI listed wetland to the south (see Figure 5 Vicinity Wetlands). The wetland examined is primarily a reed canarygrass meadow (Phalaris arundinacea, FACW), with Isolated ScrUb-ShrubClustecs and a Scrub-Shrub fringe. --. 3.22 Wetland Vegetation Most of the wetland is dominated by invasive reed canarygrass (Pha/aris arundinacea, FACW). There are isolated Scrub-Shrub clusters in the meadow which are dominated by spirea (Spirea douglasii, FACW) and Pacilic willow (Salix lucida, FACW+). Several large Pacific willows had been cut down within the past year by power line maintenance crews and remain in the wetland. This suggests that without constan . v I a .1/ forested ve et The wetland is surrounded by a Scrub-Shrub fringe. '\ On the eastern, sunny side of the wetland (under the power lines), the fringe is dominated by spirea (Spirea doug/asii, FACW) and Himalayan blackberry (Rubus procerus, FACU). Because of the orientation of the hillside and the tall black cottonwoods (Populus balsamifera) on the eastern property boundary, the wetland along there is partially shaded. The Scrub-Shrub fringe here is dominated by western crabapple (Ma/us fusca, FACW), Pacific ninebark (Physocarpus capitatus, FACW-) and black twinberry (Lonicera involucrata, FAC+) , with creeping buttercup (Ranunculus repens, FACW) and the obligate wetland plant American brooklime (Veronica americana, OBL) in the understory. See Data Sheets 1 and 2 for vegetation details. The vegetation in both sample areas, TH 4 and TH 6, meets the hydrophytic vegetation requirement for wetland determination, because more than 50% of the dominant species were FAC or wetter. The wetland is classified by the Cowardin System (Cowardin et al., 1979) as Palustrine, Emergent, Seasonally Flooded (PEM) and Palustrine, Scrub- Shrub, Seasonally Flooded (PSS). 3.23 Wetland Soils The soil profiles of both wetland test holes, TH 4 and TH 6, were similar. The A horizon (0-10") was very dark gray (10YR 3/1) loam, and the B horizon (10-16") was very dark grayish brown (2.5Y 3/2) with a few mottles. The B horizon was gravelly (up to pea size) sandy loam. The soil profile matches that of the Norma Series (No) which is mapped to the north of the site and is included LeRoy Surveyors and Engineers, Inc. Job # 5183 12 -Petrovitsky Road Site Wetland Delineation in the Alderwood gravelly sandy loam, 6-15% slopes (AgC) mapping unit. Norma soils are listed as very poorly drained with a seasonal water table at or near the surface (USDA, 1973). Based on the very low chroma (1), and low chroma (2) with mottles, the soil is hydric and meets requirement for wetland determination. (see Data Sheets 1 and 2 for details). 3.24 Wetland Hydrology Water flows through the wetland as a small seasonal stream. It enters at the north end through a culvert which passes under S.E. Petrovitsky Road. Storm water is the primary source of the inflow. Rainfall and runoff from the east half of the property as well as from the BPA power line right-of-way are additional hydrology sources for the wetland. The wetland has defined water channels as well as sheet flow. Water leaves the wetland through a culvert at the south end (see Figure 2 Site Map Survey and Figure 4 Wetland Map). Because of the moderately rapid permeability of the Norma Soil Series (USDA, 1973) and the restricted outlet, the wetland is likely to be a source for groundwater recharge. Both of the wetland sample units (TH 4 and TH 6) had some water visible on the surface as well as standing water 6" below the surface in the soil test holes. Based on the standing water, and other hydrology indicators such as oxidized root channels and water stained leaves, the wetland meets the hydrology requirement for wetland determination (see Data Sheets 1 and 2). 3.25 Wetland Determination Because the wetland met all three criteria (hydrophytic vegetation, hydric soils and wetland hydrology), it was concluded that the area was a wetland. The wetland edge was delineated and its location was staked and later surveyed by professional surveyors, LeRoy Surveyors and Engineers, Inc. (see Figure 4 Wetland Map). The wetland area was measured and determined to be 0.7 acres (30,604 If) with a 774 ft perimeter. 3.26 Buffer Description The wetland buffer extends into the northeast corner of the property. The land slopes down (approximate 14% slope) to the wetland and the hillside is dominated by black cottonwoods (Populus balsamifera, FAC). Snowberry bushes (Symphoricarpos albus, FACU) are clustered at the toe of the slope. Thimbleberry (Rubus parvifJorus, FAC') and trailing blackberry (Rubus ursinus, FACU) are prominent in less shady areas. The soil was determined to be non- hydric, and the profile (TH 5) resembled the mapped Alderwood gravelly sandy loam, 6-15% slopes (AgC). No hydrology indicators were present. (see Figure 4 Wetland Map and Data Sheet 3). 3.3 Wetland Functions Assessment Wetlands provide valuable benefits to the ecosystems in which they are located (Cooke, 1995). The most commonly assessed wetland functions include (Reppert et al., 1979; Sather & Smith, 1984): • flood and storm water control • ground water support LeRoy Surveyors and Engineers, Inc. Job # 5183 13 - Petrovitsky Road Site Wetland Delineation • erosion control • water quality improvement • habitat for wetland plants and animals • food chain support and nutrient cycling • opportunities for education, recreation, etc. The wetland functions were rated by two methods. The first method used was Washington State Department of Ecology's Methods for Assessing Wetland Functions (WFAP) (Hruby et al., 1999). WFAP uses quantifiable information collected on-site and from references which is then analyzed by a mechanistic model. The result is a scientifically based numeric index of performance for various wetland functions. The offsite wetland rated moderately high to high for water uali im rove funchons. The primary source or Walel COllihlg IIItO the wetlan is storm water runoff which is likely to carry sediments, nutrients, heavy metals and toxic organics (Pitt et al., 1995). Depending on the flow rate, wetland vegetation is capable of removing a high percentage of these pollutants by uptake, adsorption and sedimentation (Hey et al., 1994). With a constricted outlet (culvert) and 100% vegetative cover, the offsite wetland has both the opportunity and capability for significantly improving water quality. Because storm water will be impounded by the constricted outlet and the soil has moderately rapid permeability, the offsite wetland has a hi h erformance index for groundwater recharge. The offsite wetland rated onl moderate or re g pea ows a " . The offsite wetland rate mOderatel~ low for general habitat suitability largely due to its small size and lack of struc ural com I xit . Specific amphibian, fish, and mammal habitat suitabl Ity rated low or very low, while invertebrate and bird habitat suitability rated moderately low. Due to the dominance of the invasive reed canarygrass (Phalaris arundinacea, FACW), the offsite wetland rated very low for native plant richne§s. However, since the reed canarygrass dies back seasonally, the ofis1te wetlana rated high for primary production and export. See Table 2 and Data Sheet 4 for details. The wetland and buffer functions were also rated using the Wetland and Buffer Functions Semi-Quantitative Assessment Method (Cooke, 1996). Despite its small size, the wetland rated moderate for flood and storm water control functions. This was largely due to the semi-constrained outlet and its position in the upper third of the Soos Creek Watershed. For those reasons and the fact that it is a flow-through depression system, the wetland rated moderate for base flow and ground water support. The wetland rated moderately high for water • quality improvement mainly due to the amount of development upstream and its 100% vegetative cover. The wetland and the buffer areas rated moderate for natural biological support and for overall habitat functions. The moderate rating was due to the small size and lack of structural complexity. The wetland and the buffer areas rated moderate as habitat for birds and mammals largely due to the clusters and fringe of Scrub-Shrub vegetation. It rated low as amphibian and aquatic macro-invertebrate habitat due to the fluctuations in water levels. There was no appropriate fish habitat. Because the wetland is located close to the Soos Creek corridor, it can expand that vital refuge area for animals and plants in LeRoy Surveyors and Engineers, Inc. Job # 5183 14 - Petrovitsky Road Site Wetland Delineation a district that is developing rapidly. The wetland rated moderate for cultural and socioeconomic functions.

Job # 5183 15 - Petrovitsky Road Site Wetland Delineation 4.0 REGULATORY IMPLICATIONS 4.1 Wetland Rating and Buffer Requirements According to King County Code 21 A.06.1415, because the wetland is located within an area designated as urban-residential in the King County Comprehensive Plan, is smaller than one acre but larger than 2,500 square feet, and has only two classes of vegetation, it is rated as a Class 3 wetland. According to King County Code 21 A.24.320, Class 3 wetlands are required to have a 25 foot minimum buffer (See Appendix 1 for applicable King County Code sections). 4.2 Project Impacts The property owners propose dividing the parcel into 23 lots. Lot numbers 15,16,17, and 18 abut the 25 foot wetland buffer, and this will affect their use and development (see Figure 2 Site Map Survey). Although King County requires a 15 foot building setback from the edge of wetland buffers, limited uses such as landscaping and uncovered decks are allowed within the setback (King County Code 21 A.24.200). Site development necessarily includes vegetation clearing, grading and the addition of impervious surfaces, so an increase in runoff from the site is expected. Because the eastern half of the property slopes down to the offsite wetland, there is a relatively high potential for increased runoff and sediment deposition into the wetland from the development. Development is also likely to affect the hydrologic support that the property provides for the wetland. These potential impacts on the wetland can be minimized by stringent protection of the 25 ft buffer, maximizing the number of trees retained on the eastern slope, and best management practices during construction. These best management practices include installation of a silt fence and hay bales along the buffer edge, and taking the hydrology requirements of the wetland into consideration during the design of the storm water detention system.

The parcel is located in the Soos Creek sub-basin. See Appendix A-I for a vicinity map. The parcel is located in Section 23, T 23 N, R 5 E WM. This parcel is irregular in shape with the north parcel boundary formed by Petrovitsky Road and the west boundary formed by l1Sth Ave. SE. An office building, equipment yard and 2 sheds are located on the eastern half of the parcel. The remainder of the parcel is vegetated with a mixed forest interspersed with small clearings. An area just to the west of the equipment yard is dominated by Himalayan blackberry. This area slopes down from the yard to a small basin that contains a Class n wetland dominated by scrub/shrub vegetation with a developing forested vegetation class. A second wetland is located off-site to the east of the parcel • Q • approximately 20 feet from the east parcel boundary. The off-site wetland boundary appears to run parallel to the east parcel boundary ranging 30 to 50 feet from the parcel. This off-site wetland meets criteria for Class II regulation by King County. METIIODS By definition, wetlands are those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands are regulated nationally as ·Waters of the United States" by the U.S. Army Corps of Engineers, and locally by King County, Washington as per the King County Code: Chapter 2IA.24, titled, "Enyironmentally Sensitive Areas" . 1 The wetland was delineated on July 26, 1999 using the Department of Ecology Washington State Wetlands Identification and Delineation Manual and is consistent with the 1987 Corps of Engineers Wetland Delineation Manual. The Routine Determination Method as per the U.S. Army Corps of Engineers, Wetland Delineation Manual (1987) was used. The Routine Determination Method examines three parameters-vegetation, hydrology and soils to determine if wetlands exist in a given area. It is the presence of hydrology which is critical in determining what is wetland, however, since hydrologic conditions can change periodically, it is necessary to determine if hydrophytic vegetation or hydric soils exist which would indicate that water is present for long enough duration to support a wetland plant community. Data was collected in the wetland and in the upland. Information on vegetation, hydrology and soils was collected. Soil test holes were completed to a depth of 18 inches. At each test hole, a profile description, complete with texture and color of the layc.rs was recorded on the enclosed data forms. Soil chromas were determined using damp soil samples that were compared to a corresponding color chip in the Munsell Soil Color Charts. The chromas were then recorded on the data sheet using Hue (YR) and Value/Chroma. Any Hue and Value with a chroma of 1 with or without mottles or a chroma of 2 with mottles is typical of hydric (wetland) soils that have developed due to prolonged inundation or saturation by water. Background information for this report was provided by the King County Soil Survey, the King County Wetlands Inventory and King County Sensitive Areas Folio. This report includes a discussion of the on-site wetlands with respect to data collected 2 in the field and includes a wetland classification, a values and function analysis and a recommendation for regulation according to the King County Wetland Regulations. BACKGROUND INFORMATION KinK County Soil Survey The on-site soils have been mapped as AgC Alderwood gravelly sandy loam, 6-1S % slopes by the Soil Conservation Service, Soil Survey of King County Area, Washington; September, 1973. Alderwood soils are not classified as hydric; however they can contain hydric inclusions of Norma sandy loam, Bellingham silt loam, Shalcar muck, Seattle muck and Tukwila muck. See Appendix A-3 for site located on soil survey and Appendix B for description of the mapped soil types. KinK County Wetlands Inventory and Sensitive Areas Map Folio Sensitive Areas Map #S indicates one wetland within SOO feet of the parcel. This wetland is named Soos Creek 2 in the inventory and is located approximately SOO feet east of the parcel. The wetland is described in the King County Wetlands Inventory, Volume 3 South, 1990 as 134 acres in size with five vegetation sub-classes. This wetland has been given a Class 1 wetland rating in the King County Wetlands Inventory and is protected by a 100 foot buffer. The wetland and its buffer do not extend onto the parcel. See Appendix A-S for wetland data form. Priority Species There are no Washington State Priority 1,2, or 3 plant or animal species known to exist on the parcel (Washington Natural Heritage Program, 1991) nor were any identified during our field survey. The presence of priority species was determined using the printed edition and a data base search was not completed at this time. 3 WETLAND ASSESSMENT The wetland was delineated with 13 wetland boundary flags. The wetland consists of a small depression that is 5,264 square feet in size. It is overhung by forest vegetation with scrub-shrub and emergent vegetation rooted within the wetland boundaries. Young trees approximately 10 to 15 years in age are rooted in the wetland and have begun to develop a forested vegetation class. Test Hole #2 was established within the wetland to verify the presence of the wetland parameters. Test Hole #3 was located outside of the wetland just to the south. This area was dominated by western crabapple (Pyrusjusca) FACW, a common wetland plant. This area was not included in the delineation because it did not have positive indicators for hydric soil or wetland hydrology. See Appendix A-2 for location of wetland boundary flags and test holes, and Appendix G for data forms 2 and 3. Yel:etation The wetland is dominated by red osier dogwood (Comus stolonifera) FACW. Other species present in the wetland include salmonberry (Rubus spectabilis) FAC, and slough sedge (Carex obnup,a) OBL, Hooker willow (Salix hookerana) FACW, Dewey's sedge (Carex deweyana) FACU, and trailing blackberry (Rubus ursinus) FACU. Oregon ash (Fraxinus latifolia) FACW was present in the wetland as young trees and appeared to be developing into a forest canopy over the wetland. While not yet constituting 30% of the wetland cover, these trees should dominate the wetland within the next 10 years. See Appendix D for Definition of Indicator Status (OBL, FACW, FAC, etc.). Soils Test Hole #2 revealed a hydric soil comprised of a silt loam. The uppermost six inches comprised the 'A' horizon with a matrix chroma of 10 YR 3/1 without 4 mottles. This was underlain by a 'B' horizon with a matrix chroma of 10 YR 5/1 without mottles. Hydrolol:Y Water was not present at the surface or as soil saturation within the root zone at the time of the site visit. However, areas of scouring and water stained leaves were present as secondary indicators of inundation. This was determined to be adequate evidence to assume that water is present in the wetland well into the growing season. An inlet or an outlet to the wetland was not observed and it is assumed that the wetland is hydrologically isolated. It is likely that the wetland receives hydrology primarily as run-off from surrounding uplands. Seeps were not observed flowing into the wetland. Cowardin Wetland Classification The wetland is classified as Palustrine, Forested, Seasonally Flooded (pFOC). Wetland Class The wetland class was determined using Chapter 2IA.06.1415 of the King County Code. The wetland is recommended for a Class 2 designation because it is a forested wetland less than I acre but larger than 2,500 square feet in size. Functional Values Because the wetland occurs in a small basin without an outlet, it is likely that standing water is present well into the spring. Therefore, the wetland would be a source of drinking water for birds and small mammals during the winter and spring as well as providing breeding habitat for Pacific chorus frogs (pseudacris regilla) and long toed salamanders (Ambystoma macrodactylum). The wetland also captures runoff from 5 surrounding uplands and serves as an area of storm water retention. Finally, because water does not outlet from the wetland but instead remains in the wetland during the rainy season, it is likely that the wetland provides some groundwater recharge. Recommended ButTers Class 2 wetlands require 50 foot vegetated buffers measured horizontally from the delineated wetland boundary plus a 15 foot building setback according the King County Sensitive Areas Code. Buffers are to remain undisturbed. Buffer width averaging may be allowed by the County if it will provide additional protection to the wetland or enhance its function, as long as the total area contained in the buffer on the development proposal site does not decrease. OFF-SITE WETLANDS A Type 2 wetland is located just off-site to the east of the parcel. The wetland is associated with a seasonal stream that flows into the off-site area through a culvert under Petrovitsky Road. The wetland is dominated by reed canary grass (Phalaris arundinaceae) FACW. The wetland boundary is located 30 to 50 feet east of the parcel and appears to run nearly parallel to the parcel for approximately 200 feet before it veers sharply to the east. Buffers from the off-site wetland appear to intrude a short distance into the east portion of the parcel. Test Hole #1 was examined near the east parcel boundary in a small clearing near the off-site wetland. The area was dominated by common hydrophytic vegetation including western crabapple (Pyrusfusca) FACW, black twinberry (Lonicera involucrata) FACW, and creeping buttercup (Ranunculus repens) FACW. The area was determined not to be wetland because the test pit revealed soil with a non-hydric 6 two layer profile and indicators of wetland hydrology were not present. See Data Sheet Ill. POTENTIAL IMPACTS OF DEVELOPMENT The parcel is proposed to be divided into 27 lots. The wetland buffer is proposed to be maintained at a minimum of 50 feet and will be substantially greater on the east and west sides of the wetland. A road is proposed to be built just south of the wetland buffer. Because the wetland buffer is moderately dense, biological support provided by the wetland should not be diminished by development. Existing wetland hydrology will be vulnerable to impacts resulting from increased impermeable surface from development of the parcel. Impacts to wetland hydrology can be minimized through use through use of storm-water retention/detention facilities. Short term impacts to the wetland such as sedimentation can be controlled through use of standard best management practices such as placement of silt fences or hay bales around the perimeter of the wetland. Buffer from the off-site wetland located just to the east of the parcel encroaches onto Lots 18, 19,20, and 21. In general these lots slope moderately down to the off-site wetland and the wetland will be vulnerable to impacts from run-off. Silt fences or hay bales placed along the east parcel boundary should adequately protect the wetland during short term construction activity impacts. In addition, a narrow screen of native vegetation should provide adequate protection for the wetland from long term noise and light intrusion impacts. 7 SUMMARY One wetland was delineated on this approximately four acre parcel. The wetland meets criteria for a Class II system that is dominated by a scrub-shrub vegetation class with a developing forested vegetation class. The wetland is located in a depression near the middle of the north half of the parcel. King County protects Class II wetlands with a 50 foot vegetated buffer plus a 15 foot building setback. The standard wetland buffer should adequately minimize impacts to wetland biological support. Impacts to wetland hydrology should be minimized through use of storm water retention/detention facilities. Short term impacts to the wetland including sedimentation during construction of the project should be minimized by the implementation of Best Management Practices. Off-site wetlands located just east of the parcel should be adequately protected by a screen of native vegetation and best management practices. LIMITATIONS This report has been prepared for Dale Vanderschelden. It is important to acknowledge that definition of plant community boundaries is not an exact science. Different agencies and individuals may often disagree on exact boundaries andlor plant community classifications. It is the responsibility of the various resource agencies who regulate development activities in wetlands to make the final determination of wetland boundaries. Therefore, the information presented in this report should be reviewed by the appropriate regulatory agencies prior to detailed site planning andlor construction activities. 8 Given the constraints of schedules and scope of work, Wiltennood Associates warrants that the work perfonned is in accordance with the technical guidelines and criteria in effect at the time this report was prepared. The results and recommendations of this report represent professional opinion based upon the infonnation provided by the client, the client's consultants, and that gathered through the course of this wetland study.

For further information, see pages 8-10 of the Soil Survey. AgC AldeIWood gravelly sandy loam. 6 to 15% slopes. This moderately well drained soil is on uplands. It formed under conifers in glacial deposits. This soil is not classified as hydric; however, the poorly drained Norma, Bellingham, Shalcar, Seattle and Tukwila soils are often included in some areas up to 3%. Permeability of this AldeIWood soil is moderately rapid in the surface and subsoil and very slow in the substratum. Water moves on top of the substratum in winter. Available water capacity is low. Run-off is slow to medium, and the hazard of erosion is moderate. APPENDIX C: DEFINITIONS AND CRITERION The definition for wetland established by the U.S. Army Corps of Engineers (COE) was used to detennine the presence and extent of wetlands on this parcel. Section 404 of the Clean Water Act (1972) states that wetlands are: "Those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas." This criteria is based on the Department of Ecology Washington State Wetland Identification and and Delineation Manual, the 1987 Corps of Engineers (COE) Wetland Delineation Manual and the 1989 Federal Interagency Committee for Wetland Delineation (FICWD). This committee included representatives from the COE, U.S. Fish and Wtldlife Service, Environmental Protection Agency, and Soil Conservation Service, to establish technical procedures and guidelines for wetland determination and delineation. These guidelines as set forth in both delineation manuals requires that three technical criterion: (1) hydrophytic vegetation, (2) hydric soils, and (3) wetland hydrology must all be met for an area to be identified as wetland. A general summary of these criterion or parameters as defined within the COE and FICWD manuals include: Hydrophytic vegetation Criterion: This criterion is met when, under normal circumstances SOpercent or more of the composition of the dominant species from all strata are obligate wetland (OBL), facultative wetland (F ACW), andlor facultative (F AC). Hydric Soil Criterion: This criterion is met for any area having soils that are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part (USDA Soil Conservation Service, 1987). Wetland Hydrology Criterion: This criterion is met for any area having permanent or periodic inundation, or soil saturation to the surface, at least seasonally. These three criterion are the basis for all field work and wetland delineation performed on this parcel. The specific methodology used is outlined in the next section. WETLAND DELINEATION METHODOLOGY The wetland delineation followed the Routine On-site and Intermediate Determination Methods as outlined in each manual. A summary of this method includes: Plant Community Assessment. The entire project site was initially walked to identify the plant community types present. This provided a rough picture of the type and extent ofwetland(s) which exist on site. Also observed and noted were topographical features, hydrologic flow patterns, and any significantly disturbed areas. It was then determined whether normal environmental conditions were present, or human modifications had occurred to the wetland. 1 Selection of Sample Area(s). A series of sample areas or points were selected and flagged to best characterize the plant communities of suspected wetland and non-wetland areas. The approximate location of these flagged sample points were noted on a map of the project site for subsequent survey. Characterization of Plant Communities. At each sample point the dominant plant species within the tree, shrub, and herb stratum were identified and noted on a data form. Species were identified and noted according to Plora of the Paciftc Northwest (Hitchcock & Cronquist, 1973). The estimated percent areal cover and the indicator status (as listed in the National List of Plant Species that Occur in Wetlands: 1988, Washington) were also noted on the data form. It was then determined whether the hydrophytic vegetation criteria was met. When 50% or more of the dominant species have an indicator status ofOBL, PACW, or PAC, the vegetation is considered hydrophytic. Characterization of Soils. At each sample point, a hole 16 to 18 inches in depth was dug using a spade (an existing soil perk hole was used if available). Soil characteristics (matrix color, mottles, etc.) were examined and noted. It was then determined whether the hydric soil criterion was met. Hydric soil criterion is outlined on page 6 of the PICWD manual and pages 26 to 34 of the COE manual. Determination oflIydrology Criterion. At each sample point the presence of inundation by water, soil saturation by water, or other hydrologic field indicators was noted. It was then determined whether the wetland hydrology criterion was met. Wetland Determination. The completed data forms were then examined for each selected sample point within the plant communities. Each plant community meeting the hydrophytic vegetation, hydric soil, and wetland hydrology criteria was considered wetland. Data forms are numbered correspondingly to the sample points located on the final survey drawing. DETERM INA TlON OF WETLAND-NONWETLAND BOUNDARY After completing the determination method summarized above, the actual boundary between wetland and non-wetland was delineated. This delineation was completed by: 1. recognizing obvious wetland and non-wetland areas, 2. identification of transitional areas between the two areas, 3. final determination of the boundary by further sampling of vegetation, soils, and hydrology. The wetland Boundary was then flagged with numbered orange flags with WB (Wetland Boundary) written on them. The approximate location of these flags was then noted on a map, if available, for subsequent survey. * Important Note: The exact location of the boundary between wetland and non-wetland areas may be dimcult to determine, especially if transition areas are more gradual. In cases such as this the wetland boundary is determined, after further sampling, by using the best possible professional judgment. 2 APPENDIX D: DEFINITION OF PLANT INDICATOR STATUS The following plant indicator status categories and their symbols are derived from the Wetland Plant List, Northwest Region, USFWS, Washington, D.C. (Reed, 1988) Symbol OBL FACW FAC FACU UPL NI NL Definition of Plant Indicator Status Obligate wetland plants are nearly always found in wetlands (estimated probability 99% or more) Facultative wetland plants usually found in wetlands (estimated probability 67-99%) Facultative plants are equally likely in wetlands and uplands (estimated probability 34-66%) Facultative upland plants usually in uplands (estimated probability 67-99%) Upland plants are nearly always in uplands (estimated probability 99% or more) Not indicated plant species are not determined due to lack of sufficient information Not listed in the "National List of Plant Species that Occur in Wetlands" indicating the lack of information for this species. Note: The "National List of Plant species that Occur in Wetlands" uses a plus (+) or minus (-) sign to specify a higher or lower portion of a particular wetland indicator frequency for the three facultative-type indicators .. .). (from section 2.5, page 6, Federal Manual for Identifying and Delineating Jurisdictional Wetlands) . APPENDIXF Wetland Values and Functions It is important that those involved in wetland regulation and management understand their functions and values. Knowledge of these roles can be a key factor in the design and implementation of wetland inventories. Not all wetlands provide each function or value nor do they provide them to the same degree. Variations occur because of wetland type and characteristics, as well as regional and local influences. Some local governments try to distinguish how functions and values relate to their community and region. The following is a brief summary. Water Supply With the growth of urban centers and dwindling water supplies, wetlands are increasingly important as a source of surface and ground water. They can function as recharge areas where water soaks into the soils, replenishing ground water supplies. Wetlands are also areas where ground water moves to the surface through springs and seepage, often collecting in pools and ponds, and supplying critical reserves during periods of drought. Flood Control Wetlands are valuable in reducing the impact of flooding. They have the ability to store and slow the flow of water from upland run-off. If a wetland is associated with a river in a flat valley, the wetland and its vegetation reduces the height and velocity of flood peaks. Some wetland soils can store large amounts of floodwater and gradually release them downstream. Construction in flood plain wetlands causes increase flood heights and rates, and an associated increase in flood damage. Erosion Control Vegetated wetlands serve as natural buffers from the effects of tides, waves, wind and river currents. They dissipate the energy of these erosive forces. The fibrous root systems of wetland plants bind and stabilize banks, protecting the shoreline from erosion. On the coast, they can limit wave generation, slow and absorb the impacts of wave energy, and thereby protect inland areas from storm damage. Construction of bulkheads, rip-rap, and other banked hardening stabilization techniques simply transfer the erosive energy to neighboring areas. Pollution and Sediment Control Wetlands protect and improve the quality of surface and ground waters by removing sediments, nutrients, heavy metals, and hazardous chemicals. Wetlands vegetation filters particulate matter from the water. When moving water comes into contact with vegetation, its flow is slowed and sediment falls out of suspension. The root systems trap the sediment, reducing siltation in downstream water bodies. Substances such as nutrients, pathogens, and many chemicals are often bound to the surface of sediment particles. Thus, sedimentation reduces both organic and inorganic pollutants. These pollutants may be released when wetland soils are disturbed. Wetland vascular plants and algae also absorb nutrients and chemicals. The micro-organisms utilize dissolved nutrients and break: down organic matter. Research is underway to determine the impacts of utilizing wetlands as tertiary waste treatment facilities. Wildlife Habitat Wetlands, the interface between land and water, are among the richest wildlife habitats in the world. They provide the conditions essential for the breeding, nesting, feeding, and protection for many species of waterfowl, mammals, reptiles, and amphibians. These conditions include abundant water, diverse and rich vegetation, and adequate cover. Many of these species are "obligates" or dependent upon the wetland for their survival. Some such as the beaver spend their entire lifetimes in the wetland environment. Others like the salmon inhabit it for shorter, but critical, parts of their life cycle. Numerous species (such as deer and raccoon) depend on wetlands as a source of drinking water, food, and winter cover. Wetlands are as critical to the needs of these species as they are to those that depend solely on wetland habitat. Though many waterfowl nest primarily in northern freshwater wetlands, they use wetlands through out the county while migrating and for over-wintering. Birds such as herons, egrets, rails and harriers depend upon wetlands for their survival. Both salt and freshwater wetlands are important spawning, nursery, feeding, and wintering areas for sport and commercial fish and shellfish. Wetlands also support many endangered plant and animal species. Although wetlands constitute only 5 per cent of the nation's lands, close the 35 per cent of all rare and endangered animal species are dependent upon them. (McMillan, A. 1986) Food Web Productivity Wetlands play an important part in the food web. Coastal wetlands are among the most productive areas in the world. Solar energy is utilized by wetland plants to produce hundreds of pounds of nutrients per acre of salt marsh annually. The vegetation dies, decays, and is broken down to form a nutrient-rich ·soup· called detritus. This rich food source is converted by micro- organisms into basic nutrients and elements for use by vascular plants and phytoplankton (minute floating plant life). The phytoplankton are consumed by zoop1ankton (minute floating animal life). the detritus and plankton's are carried into tidal creeks, and bays and are consumed by invertebrates such as oysters, shrimp and crabs. they in tum are preyed upon by other animals including humans. It has been estimated that 90 per cent of the important commercial marine species either spend their entire lives in estuarine wetlands or require estuaries as nursery grounds (Kusler, J. 1983). Freshwater wetlands also provide food, habitat, and spawning grounds for many other species of fish. Education and Research Coastal and inland wetlands provide unique opportunities for education and scientific research. Due to the land-water interface, diversity of vegetation, topography, and the resulting varied habitats, wetlands are ideal for studying plant and animal life. Because ecological relationships are easily observed, they are excellent locations for teaching environmental science. The complex ecological relationships of wetland systems make them valuable areas for scientific research as well. Recreation and Aesthetic Values Wetlands are areas not only of great diversity but also of great beauty. They provide open space and contrast for both visual and recreational enj oyment, especially valuable in urban areas. Visitors include photographers, bird watchers, hikers, boaters, hunters, fishers and natural history enthusiasts. Appreciation and use of wetlands as a recreational resource is steadily increasing on both a national and state-wide basis. National, wetland-dependent waterfowl are hunted by over 2 million hunters. Nisqually National wildlife Refuge, near Olympia, Washington has had a 300 percent increase on visitor use since 1977.

Attached below is an outline listed by section according tOJ'our letter_. _ Section A & B A revised storm water treatment plan has been prepared by Barghausen Consulting Engineers, Inc. that satisfies Core requirement NO.8 and Chapter 6 in the King County Surface Water Quality Manual. Twenty copies have been included for your review. Per our last meeting, the plat has been revised to convey roof runoff from lots 1 to 5 and 19 to 23 to the onsite wetland in Tract B. Tract C was also added to allow for the installation of an interceptor swale that will convey additional runoff to Tract B, Twenty copies of a revised site plan has been attached with this resubmission. Section C Lots 16, 17, 19 and 23 were designed to have adequate setbacks adjacent to the Tracts B & D (Sensitive Areas). In order to design lot 19 with enough setback from the Sensitive Area in Tract B, the buffer had to be encroached to within 32.5' (65% of buffer width) at the northeast section of the lot. This resulted in an encroachment amounting to area 687 SQ. FT. KCC 21A.24.320 permits the use of wetland buffer averaging, provided " ... it will provide additional protection to wetlands or enhance their functions, as long as the total area contained in the buffer on the development proposal site does not decrease." To comply with this section of the King County Code, an additional 1,456 SQ. FT. will be created within Tract B as well as installing 8 trees and 19 shrubs per "The Sensitive Areas: Restoration and Enhancement in King County Understanding the Process and Technical Assistance in preparing a Plan" guidelines. This is in addition to the 56 trees and 131 shrubs already proposed in the June 27, 2003 letter for buffer enhancement.

VanDerschelden, owner! applicant Kim Claussen, Planner III, Current Planning Section, LUSD Pete Dye, Senior Engineer, Engineering Review Section, LUSD Nick Gillen, Senior Ecologist, Critical Areas Review Section, LUSD PLAT SCREENING TRANSMITTAL 1. Drainage: a. Stormwater Design/On-site Wedand Impacts: Item 1c from our October 29, 2002 "screening" letter remains unaddressed. Our concern, as noted in Item lc, is that the volume of surface water runoff conveyed to the Tract B wedand, with the proposed stormwater design, will greatly increase folloWing the development of the subject plat. This will have a deleterious effect on the existing vegetation in the wedand, likely causing the mortality of existing trees. Thus, the proposed design is in conflict with KCC 2lA.24.330H1. Please submit a revised conceptual drainage plan which addresses our comments in Item 1c from our October 29, 2002 letter. Please note that compliance with the level one flow control standard, as discussed on page 1-31 in the King County Surface Water Design Manual, is not sufficient to address the requirements of KCC 21A.24.330H1. The level one standard is only intended to prevent increases in certain peak flow rates, but will not prevent increases in runoff volumes and flow durations, which can impact wedand hydrology and wedand habitat characteristics. b. Stormwater Design/Downstream Wedand Bog: Recent field inspection by King County staff indicates that a bog wedand is located downstream from the proposed plat. This bog is mapped in the King County wedand inventory as Soos Creek Wedand #2, and the enclosed map shows the approximate location of the bog. The hydrology ofthe bog is related to the Soos Creek stream system, and the bog receives surface water runoff from the Petro Vista site. As oudined in Core Requirement No.8 and Chapter 6 in the Surface Water Design Manual, all projects which discharge runoff to a sphagnum bog wedand must meet special design requirements for water quality. Page 6-12 in the Drainage Manual provides a summary of design options which are available for water quality treatment. Please update the conceptual drainage plan for Petro Vista to reflect the applicable water quality designs. 2. Wedand Buffer Averaging: KCC 21A24.320 permits the use of wedand buffer averaging, provided " ... it will provide additional protection to wedands or enhance their functions, as long as the total area contained in the buffer on the development proposal site does not decrease." Please provide an analysis from a qualified biologist as to how, and to what degree the buffer averaging proposal will provide "additional protection" to the Tract D wedand, or enhance its functions. In this regard, we have included a copy of an administrative rule adopted by our department, which addresses the required contents of a buffer averaging analysis, and sets out further criteria for evaluating the acceptability of buffer averaging proposals. 3. Recreation Space: We have noted that you have modified your plat proposal in order to comply with the recreation space design requirements of KCC 21A.14.18OC; however, in our view, conflicts with this Code section still remain. They are the following: • A portion of the north-south leg of Tract A is too narrow. KCC 21A14.18OCS Since no credit towards the rec. space requirement can be given for the portion of the tract which is narrower than 30 feet, insufficient area is being proposed for recreation space. • KCC 21A14.18OC3 requires that the "topography, soils, hydrology and other physical characteristics" of the rec. tract be " ... of such quality as to create a flat, dry, obstacle-free space ... " (emphasis added) KCC 21A14.18OCI requires that the rec. tract "[b]e of a grade and surface suitable for recreation improvements and have a maximum grade of five percent." We question whether these grade requirements can be met. If you choose to keep the rec. tract in its present proposed location, please provide a conceptual grading plan to show how the required grades can be achieved. • K CC 21A 14 .18OC3 requires that the rec. tract be " ... in a configuration which allows for passive and active recreation. " (emphasis added) In addition to the tot lot play equipment required by KCC 21A14.180E1, sports/play equipment will also be required for older children, e.g., a sport/basketball court. The "L" shaped configuration of the proposed rec. tract does not readily lend itself to the provision of active recreation facilities. • KCC 21A14.180C4 requires that there be " ... good visibility of the [rec. tract] site from roads and sidewalks." It is questionable whether this standard will be achieved at the apex of the proposed "L" shaped site. 4. Width of Lot 17: KCC 21A24.200 requires a IS-foot building setback from Tract D, a sensitive areas tract. KCC 21A12.030 requires as-foot side yard setback from the west property line of Lot 17, if it is developed with a detached single-family residence. . If Lot 17 is developed with a townhouse, then obviously the townhouse can abut the Lot 17 west property line (see KCC 21AI2.030B3). Thus, depending on whether Lot 17 is developed with a detached single-family residence or a townhouse, the width of the building pad will either be 10 or IS feet wide. This seems insufficient for a viable building site. Lot 17 should be revised accordingly. Please submit 2S copies of a revised site plan and eight copies of all other requested documents. <1l (;)0> .-0 > III o I N l:;O~ ~$ § I ' : I , , KING COUNTY PUBLIC RULES DEPARTMENT OF DEVELOPMENT AND ENVIRONMENTAL SERVICES Sensitive Areas Code. Presumption of Salmonids, Sensitive Area and Buffer Modifications, and Mitigation Requirements Effective Date. May 4, 2000 Amended. July 19, 2002 before approving the sampling protocol. Sampling shall not be conducted when the stream or other water body is essentially dry or if flows are intragravel. The department may require additional sampling if it determines that conditions, such as flooding, drought, low water flows or other circumstances, impaired the accuracy of. the sampling used in the surveys. D. If sampling includes electrofishing the stream or other water body or using other capture methods, the sampling shall be conducted in compliance with the conditions of a Washington State Department of Fish and Wildlife Scientific Collector's Permit and any other required state or federal permit, including any permit required under Section 10 of the federal endangered species act. Unless a change in the survey window is approved by the department on a case by case basis because local stream conditions require a change, sampling conducted by electrofishing shall be conducted during the following periods: 1. For a stream or other water body with anadromous access, the sampling shall only be conducted between March 1 and July 15. The department may approve sampling for over-wintering salmonids between January 1 and March 1 after consultation with the Washington department of fish and wildlife and affected tribes; and 2. For a stream or other water body with no anadromous access, the sampling shall only be conducted between May 1 and July 15. E. Fish presence surveys using visual detection methods, trapping, rod and line surveys, or netting may be used to demonstrate fish presence at any time of year, subject to conditions of a Washington State Department of Fish and wildlife Scientific Collector's Permit and any other required state or federal permit, including any permit required under Section 10 of the federal endangered species act. 21A-24-016 Buffer width averaging for stream and wetland buffers. A. Under K.C.C. 21A.24.320B and 21A.24.360B, the department may approve a proposal for buffer width .averaging if the applicant demonstrates that the total area contained in the buffer on the site does not decrease and that the proposal will either provide additional protection to the wetland or stream, or enhance the functions of the wetland. B. The applicant for buffer width averaging shall provide the department with an analysis acceptable to the department of existing buffer functions that addresses the following issues: Page 4 of 17 KING COUNTY PUBLIC RULES DEPARTMENT OF DEVELOPMENT AND ENVIRONMENTAL SERVICES Sensitive Areas Code: Presumption of Sa1monids, Sensitive Area and Buffer Modifications, and Mitigation Requirements Effective Date: May 4, 2000 Amended: July 19, 2002 1.

The risk of creating trees likely to be designated as hazardous as a result of the development; 4. The opportunity for additional protection to the stream or wetland or enhancement to the wetland; 5. The location of the floodway and the lOa-year floodplain; 6. The presence of any migrating river channel; 7. The impact on functions and values of natural resources that will result from the proposal; 8. Health Department requirements for on-site sewage disposal systems; and 9. Any other information determined by the department to be reasonably necessary to analyze the proposal. C. The department shall approve an application for buffer width averaging only if the applicant demonstrates to the department that the proposal for buffer width averaging meets the requirements of K.C.C. 21A.24.320B or 21A.24.360B. The department shall apply the following minimum standards to the proposal: 1. The minimum buffer width shall not be less than sixty- five percent of the standard buffer width, unless the applicant demonstrates that a proposal that reduces the buffer to less than sixty-five percent of the standard buffer width will result in substantial enhancement to the buffer's overall function. The buffer shall be monitored by the applicant pursuant to 21A-24- 037; 2. The additional buffer shall be contiguous with the standard buffer; 3. Unless a building setback variance has been issued, the yard area between any structure and the reduced buffer shall meet minimum building setback requirements. If the buffer width averaging allows a structure or associated yard to intrude into the normal buffer area, the resulting yard shall extend no more than 15 feet from the edge of the structure's footprint toward the reduced buffer; and 4. In order to demarcate the buffer edge, permanent signs identifying the presence of a sensitive area shall be required between the edge of the yard and the buffer. Page 5 of 17 January 15,2003.

Drainage: Additional information is required to satisfy the requirements for an off-site drainage analysis. The revised Level One Downstream Drainage Analysis, dated September 13, 2002, does not contain a downstream map or detailed description of the downstream conveyance system. Please provide the following information as a supplement to the drainage analysis: a. As described on page 2-1 in the King County Surface Water Design Manual (KCSWDM), the first task requires preparation of a map depicting the downstream flow path. The study area must extend downstream of the proposed project discharge location to a point on the drainage system where the site constitutes a minimum of 15 percent of the total tributruy drainage area, but in no event less than 114 mile. b. The requirements for Task 4, shown on page 2-12 of the KCSWDM, also require that the drainage system be addressed using the off-site Drainage System Table shown in reference section 8-B. Please prepare the table with the corresponding drainage map and describe any relevant problems or field observations. The Level One analysis must detennine if the downstream drainage conditions include any of the three types of downstream problems listed on page 1-20 of the Manual. c. The conceptual drainage plan for the subject plat proposes to discharge collected stormwater flows into the forested wetland within Tract B. Since this wetland is a closed depression, the additional stormwater runoff resulting from the development of the site will likely adversely affect the wedand vegetation, hydrology, and surface water quality. To minimize potential adverse impacts, the discharge to the Tract B wedand must be limited so that it matches pre- development flow rates and volumes to the wetland. To accomplish this, please prepare a revised conceptual drainage plan which shows the conveyance of a inajority of the stormwater runoff from the plat away from Tract B. We recommend that you determine the number of developed lots whose roof drainage must be collected and dispersed into Tract B to match the pre- developed flow rates and volumes to the wedand. The remaining collected stormwater runoff from the plat must be conveyed for controlled release, to the downstream system east of the site. Please refer to the closed depression standards in Section 3.3.7 in KCSWDM. The existing wetland/ closed depression in Tract B will affect the detention sizing for the plat, since most of the site in its pre-developed condition does not release surface runoff to the downstream properties. The conceptual drainage plan should also identify which lots, if any, are proposed for dispersion, versus connection to the detention facility. 2. Wetlands/Streams: a. The wetland lying along the nottheast margin of the subject property has been shown as a Class 3 wetland with a 25-foot-wide wetland buffer on the proposed plat map. This is incorrect. It is "hydrologically connected" to and part of a larger dass 1 wetland which lies east and southeast of the subject property (mapped as Wetland # 5402 in King County's wetland mapping system, also see KCC 21A.06.1415). Therefore, please submit a revised plat map which includes a 100-foot-wide wetland buffer, per the requirements of KCC 21A24.320A1. b. A stream, Big Soos Creek (I'ributruy 0072), flows through the above-referenced wetland. This stream is a dass 2 stream under King County's classification system (KCC 21A06.1240), and is presumed to contain salmonids per Public Rule 21A-24-013. Please locate the stream channel for this stream by field survey in the area east of the sire, and provide a 100-foot-wide buffer from the "ordinruy high water mark" or "top of the bank," per the requirements of KCC 21A.24.360AZ and 21A.06.825. Also, please provide a revised plat map showing the stream location and stream buffer. Note that per KCC 21A.24.180, the stream buffer and adjoining wetland and wetland buffer, where they fall within the subject property, must be shown in a sensitive areas tract in the proposed plat. c. With regard to the above-noted re-design of the plat layout which is required to address increased wetland and stream buffers, please evaluate the possibility of relocating the route for the proposed new sewer line connection to the existing sewer system, to avoid adverse impacts to the Class 1 wetland, and adjoining wetland and stream buffers. 3. Sewer Trunk Line: The original plat map (Sheet PPl) submitted with the subject plat application, received June 17, 2002, showed a sewer line bisecting the site in a notthwest-southeast direction. It was unclear from the map whether this line was an existing line, proposed line, or simply a mapping error. Please indicate which is the case. If this sewer line is an existing line, please indicate whether this line is proposed to be removed, including from the Tract B wetland, and if it will be relocated, identify the location for the new line. 4. Traffic Study: The intersection of l1Sd> Ave. SE/SE 176,h St. (aka Petrovitsky Rd.) appears to have some entering sight distance constraints to the west, due to the combined effects of roadway profile, topography, and vegetation. As a result, please provide a traffic impact analysis, prepared by an engineer licensed in the State of Washington with expertise in traffic engineering, which addresses the following. a. Identification of the existing entering sight distance (ESD) and stopping sight distance (SSD), as defined in the King County Road Standards, currently available at the intersection. b. Identification of the potential corrective measures that could be undertaken to achieve the ESD and SSD standards, as established by the King County Road Standards. c. An evaluation of the three.year accident history at the intersection. d. A pre·development and post.development calculation of the levels·of·service at the intersection, and an evaluation of the length of the 95 m percentile queue of northbound vehicles on 118th Ave. SE at the intersection. This analysis should also identify whether the northbound vehicle queue will, in a post.development condition, regularly back up south of the plat entrance road, blocking the intersection into the plat, and whether the construction of a northbound left tum lane on 118m Ave. SE is warranted with the development of the subject plat. 5. Significant Tree Preservation: KCC 21A38.230 concerning significant tree preservation applies to the subject property. Therefore, please provide the following, unless sensitive areas occupy 25% or more of the site (see KCC 2IA.38.230B1h): • A survey of significant trees on the site, identifying the location, size and species of significant trees on the property. (Note that the definition of a "significant tree" can be found in KCC21A06.1167.) • A conceptual tree preservation/planting plan, which implements KCC 21A.28.230. (please contact Jim Ballweber, LUSD Site Development Services Section, if you have questions regarding the implementation of this Code requirement.) If sensitive areas occupy 25% or more of the site, please provide area calculations to support this conclusion. 6. Subdivision Densitv and Dimension Calculations Worksheet: Please submit a revised worksheet to address the following: a. Based on Item 2 above, the area in the subject plat in sensitive area tracts will increase. Please revise the worksheet accordingly. b. The area shown for the "[gJross horizontal area of the project site" on the worksheet differs from that shown for the site area on the plat map (Sheet PP1). Please resolve this discrepancy and either revise the worksheet or the plat map accordingly. c. On page 3 of the worksheet under Roman numeral "V," you have indicated that 12,278 square feet of area is required by King County for recreation space. This is incorrect. Based on the provisions of KCC 21A14.180A and the development of 23 lots in the plat, 8,970 square feet of recreation space is required. Please revise this portion of the worksheet to be consistent with the requirements of KCC 21A14.180A and the number of lots proposed, not the amount of recreation space provided in the project. d. Regarding Item "VII" on page 4 of the worksheet, this section need not be completed unless you are seeking an adjustment to the minimum density requirement for the plat, based on the slopes on the property. (Note that under the present proposal, minimum density is not an issue, since the project contains 23 lots, the maximum number of lots that can be developed under the "base density" for the site.) If you choose to complete Item "VII" on the revised worksheet you submit, please also submit a topographic map of the property with the various slope increments delineated on the map, as required by KCC 21A.12.087B1. Please also identify the square footage of each of the slope increment areas on the site. Note that only the portion of the site comprising the "Net buildable area" should be considered in determining the reduction of the "Minimum Density Factor" (see KCC 21A.06.797 and 21A.12.087). 7. Lot Fronta~e: The road frontage of certain lots proposed in the subject plat is too narrow and cannot comply with the King County Road Standards. KCRS Sec. 3.01C3 and Dwg. 3-004 require that residential driveways be set back a minimum of five feet from side property lines, and have a minimum driveway width of ten feet. Consequently, each proposed lot must have a minimum road frontage of 20 feet (measured along the chord for lots with a curved front lot line). Please revise the proposed plat map accordingly. 8. Recreation Space: Tract E in the subject plat is proposed presumably to comply with the on-site recreation space requirements of KCC 21A.14.180 and .190. We have noted that this tract does not comply with the design requirements of KCC 21A.14.18OC, most notabzC4 and C7. Tract E does not have good visibility from the cul-de-sac bulb of SE 176 Court, and it does not have sufficient street frontage. Please revise the plat design to comply with KCC 21A.14.18OC. 9. Detached Single-F ami)y Residences vs. Townhouses: It is our understanding that detached single-family residences are the intended use for the proposed lots, not townhouses. If this is incorrect, please modify the plat map and the environmental checklist accordingly. Please submit 25 copies of a revised plat map and eight copies of all other requested documents. ® King County Deparhnent of Development and Environlnental Services 900 Oakft;dale Avenue Southwest Renton, WA 98055-1219 September 23, 2002 Paul E.

Leroy Surveyors & Engineers, Inc. 1103 Shaw Road Puyallup, WA 9B372 RE: Notice ofIncomplete Application -File No. L02P0012 Proposed Subdivision of Petro Vista Dear Mr. Green: The purpose ofthis letter is to notify you that on July 2, 2002 the Land Use Services Division (LUSD) determined that the above-referenced application is incomplete under the current requirements for a complete application, as specified in KCC 19A.OB.150 and 20.20.040. This initial determination is intended for the purposes of determining the vesting date, and for applying the time period established by KCC 20.20.1 00. The following information is needed for this application to be considered complete: •. The preliminary plat map and topographic map (Sheets PPI and Sl) must be stamped by a licensed land surveyor. These maps have been stamped by an engineer, but do not contain a surveyor's stamp. KCC 19.0B.150B • The plat map and topographic map must contain notes indicating that the contours shown on these maps are based upon a field survey of the site. Two temporary benchmarks (along with appropriate elevations and datum) must also be established within the site, and shown on the maps. KCC 19A.OB.150B2 The temporary benchmarks must be consistent with KCC 19.0B.130. • The portions ofthe subject plat proposed for dedication to King County must be labeled as such (e.g., the proposed on-site road and stormwater facilities tract). KCC 19.0B.150B5 MAIN FILE copy Petro Vista July 2, 2002 Page 2 oD • All easements listed in the title report for the subject property which are capable of being plotted, must be shown on the plat map and labeled. KCC 19.08.150B6 • Various utility lines are shown crossing the site on the plat map, most notably a sewer line running diagonally through the property and exiting the site near the southeast comer, and a power line entering site along the north boundary. If easements are proposed to be created in the subject plat for these utility lines, the location of the easements should be shown, and notes added to the plat map to indicate these easements are proposed. Alternatively, if any existing easements crossing the site are proposed to be vacated or relocated, they should be labeled as such on the plat map. KCC 19A.08.l50B4 • As shown on the plat map, there are two wetlands present on the site. The boundaries of these wetlands, within the site, must be located by field survey. Please provide notes on the plat map indicating this has been done. KCC 19A.08.l50B7 • Show existing property lines and buildings within 100 feet of the site, and identifY the zoning of these parcels on the plat map. KCC 19A.08.150BIO • The Level 1 Downstream Drainage Analysis submitted with your application is lacking a number of items required by the King County Surface Water Design Manual (see enclosed guidelines concerning Core Requirement No.2 -Off-site Analysis Submittal Requirements). Please submit a revised Level 1 analysis which covers all the requirements specified in Sections 1.2.2 and 2.3.1.1 of the Surface Water Design Manual. KCC 20.20.040AI4 We have noted that the plat map submitted with your application (Sheet PP 1) is very difficult to read, in part because of the amount of information contained on the map. We request that you revise this map to make it more readable. We suggest the following changes: • Darken up the proposed lot and tract boundaries. • Eliminate the lines depicting the existing parcels within the site. • Lighten up the lines related to utilities. The location of the proposed sewer and water conveyance pipes, as opposed to the easements for these pipes, need not be shown, however all existing and proposed easements for utilities should be identified on the map. • Lighten up the lines depicting the existing buildings on the property. • IdentifY the proposed lot sizes in a table, rather than on the plat layout. Petro Vista July 2, 2002 Page 3 00 • Remove all superfluous lines, e.g., the diagonal lines entering the site near the northwest and southwest comers of the property, which intersect on the north margin ofthe turnaround bulb. • Provide a street name for the proposed on-site road, e.g., SE 176"' Court or Road "A." LUSD will keep this application "on hold" pending receipt ofthe above-noted information required for a complete application, during which time no further review will take place. Pursuant to KCC 20.20.050E, if all the requested information is not received within 90 days from the date of this letter, your client's application will be canceled. No time extensions will be granted. Should the application be canceled, you will be required to submit a new application. Please note that once we receive the above information and are able to deem your client's application "complete," per the initial submittal requirements of KCC 19 A.OS.lS0 and 20.20.040, it is likely, upon further review, that we will seek additional information from you in order to complete our review ofthe proposal.

The Soos Creek channel on the north side of l1eu Ave SE between Units c and D on the attached site plan was fairly full with a water level about 3-4 feet below the road level. ~he debris level along the edge of the channel showed that a water level had been about 1-1.5 foot higher than the existing level. aased on the slow rotation of the water surface at the south end of the channel, the channel was slowly draining south through the 2-24inoh culverts under 118~ Ave SE. The tennis oourts on the south side of the road were wet and looked as though several feet of water bad been ponded there recently. The NW-SE channel located just south of the Recreation Building was very full and appeared to be draining SE at the outlet of the culverts under 11B'". Via phone, I talked to Carter on 11-20-01. She said the channel north of 11a~ had flooded to within about otte foot of the top of its banks and about 2 feet of water had ponded in the tennis courts on the south side of lle th • After confer~ing in our office with Larry Gettle and Mike Malnerich, I called carter back on 11-28-0~ and told her the flooding in the channel and tennis courts were normal for a heavy 3 day raiofall with partial plugging of one or more downstream culvert entrances. I thanked her for her complaint and gave her our 20G-~96-1900 complaint number and the roads 24-hour complaint number at 206-296-8100. The photos I took at the site were not found in my digital camera. 09/13/2002 PRI 08:00 [TX/RX NO SllS] IlIi 003 SEP.13.2002 8:26AM KC WLRD R.b NO.'3'34 P.4/4 c.A~'t£.. 1=I>.~-K Lol4.b (\ e£>Z ':':E. ~!T~ 1 -rB: t:,Sb £7 N5.. ,:1...00 t -0 7tJ-:t. t.1t rl-e..r .

More particularly, the site is located at 11925 S.E. Petrovitsky Road and is easily viewed on the enclosed Exhibit A - Vicinity Map, which depicts the exact location of the project site. The existing topography of the site has slopes ranging from 2 percent to 30 percent. The site tends to slope towards the north-central portion of the site and runoff collects in a closed depression and wetland area there. The vast majority of the site consists of second growth forest; however, there is a construction company office that is leased along the northeast comer of the site with another metal building behind it. More towards the center portion of the site is a storage yard for construction materials adjacent to the metal building. There is also a wetland area along the eastern property boundary of the site. The Bonneville Power Administration (BPA) transmission easement forms the eastern property line of the site. S.E. Petrovitsky Road forms the northern property line and l1Sth Avenue S.E. forms the eastern property line. An existing residential development zoned R-6 lies south of the site. The wetland area in the north-central portion of the site actually is created by a closed depression where runoff is infiltrated from the upstream basin and on-site basin when it collects there. However, during major storm events the wetland area does fill up and overtop into the S.B. Petrovitsky Road right-of-way. UPSTREAM DRAINAGE ANALYSIS Based on the USGS Quad Map and our site visit, it appears that there is upstream flow onto and through the site. For the most part, areas south of the site and from l1Sth Avenue S.E. tend to drain onto and through the site. Please see Exhibit C -Upstream Basin Map for a complete overview of the upstream basin contributing runoff to the property. During major storm events this upstream basin may be actually larger in size than what is depicted on the Upstream Basin Map because runoff tends to overtop the right-of-way of llSth Avenue S.E., which conveys runoff in ditches on both sides of the road. Runoff from the west may cross IISth Avenue S.E. and discharge into the subject property as well. The property owner immediately south of the subject property indicated during the site visit that runoff from the upstream basin fills up within the subject property and backs up onto his property, prior to overtopping onto S.E. Petrovitsky Road. llOl1.001.doc [IPl/dml EXHIBIT A Vicinity Map /WIr oLIn r aM(TfH~ o Pl .',. ~_;; ,'t1111 \ "i ~i ~ 3RO ,~~ )T .j ;>1- 1I\\\ I" I I !RENTOIN " ~' ~,'" ".: ,i _L_'_' __ ~ ~ ____ ~_ GI rill LLI~ ·28 SITE /' SOURCE: THE THOMAS GUIDE (USED BY PERMISSION) I , . len, I l{[SURf [sr,ufS ~IP !\(tlr'\'rm/[ lof'i' :," GOLF Ct}U1lS[ FAIRWOOD I , VICINITY MAP , .~ :',' _,1 I .;~ .

The Basin Reconnaissance Summary Report indicates a project is slated to be constructed in Boulevard Lane Park, which will be to construct a berm and proportional control weir there if the wetlands can maintain their integrity after the construction of the berm and weir. It is not known if this project has been constructed or not; however, it was proposed to help mitigate flow control problems in the upstream basin of Soos Creek. • Critical Drainage Area Maps: According to the Water Quality Applications Map in the 1998 King County, Washington Surface Water Design Manual (KCSWDM), basic water quality treatment is required. According to the Flow Control Applications Map, also in the 1998 KCSWDM, Level 1 Flow Control is required as a minimum. However, in spite of these water quality and flow control applications maps, King County has indicated in a letter dated February 20, 2003, addressed to Robert King of LeRoy Surveyors and Engineers, Inc., that for water quality purposes the site drains to Soos Creek Wetland No.2, which is a sphagnum bog wetland that requires a special type of water quality pertinent to sphagnum bog wetlands. In addition, Level 1 Flow Control is not sufficient to meet the requirements for flow control for this project since it will impact the Tract B wetland with an increase of runoff volume, which will have a deleterious effect on the existing vegetation in the wetlands. • Floodplain and Floodway FEMA Maps: Please see the enclosed Exhibit D -FEMA Map utilized for this analysis. Panel No. 983 of 1,725, Map No. 53033C0983 F, revised May 16, 1995, and as indicated by this map, the proposed project site potentially does lie within the floodplain or floodway of a stream along the eastern property line adjacent to the Soos Creek tributary. Please refer to Exhibit D -FEMA Map. • Other Off-Site Analysis Reports: A review of Exhibit I -Basin Reconnaissance Summary Report and the site investigation were conducted in preparation of this Levell Drainage Analysis. The United States Department of Agriculture Soils Conservation Service Map is also provided. See Exhibit F. • Sensitive Areas Folios: Based on a review of the King County Sensitive Areas Map Folios, it was found the subject site does not lie within any sensitive area; however, there are a couple of wetlands on the site and Soos Creek lies immediately east of the site, whose floodplain may impact the site, depending on topographic features. • Road Drainage Problems: This is not applicable. • United States Department of Agriculture King County Soils Survey: Based on the soils map for this area, the entire site is located within Alderwood-type soils, which are known to be till-type soils. • Wetland Inventory Map: The Wetland Inventory Map for this area is included. The site has one wetland on it; however, the entire site drains to Soos Creek Wetland No.2, which is a large 1101 LOOLdoc [IPlldml wetland comprising 134 acres. This known to be a sphagnum bog wetland and IS highly sensitive. • Migrating River Studies: This is not applicable. 11011.00l.doc [IPI/dm] EXHIBITD FEMAMap NAnONAL FLOOD INSURANCE PROGRAM FIRM FLOOD INSURANCE RATE MAP KING COUNTY, WASHINGTON AND INCORPORATED AREAS PANEL 983 Of 1125 MAP INDEX FOR PANELS NOT PRINTED) CONTAINS: COMMUNITY KING COUNTY.

WETLAND EVALUATION SUMMARY: Om was collected in the five categories shown below. Within each category the data was evaluated to produce numerical values. Composite VIIlues for each category were produced In order to compare each wetland to other wetlands in its sub-basin and in King County. The result of that comparison was a percentile rank. The percentile is expressed on a scale of one hundred and Indicates the percent of wetlands that scored equal to or below that particular site. For example, a percentile rank of 80 under sub-bssin means that the wetland scored equal to or better than 80 percent of aU sites within the sub-basin for that evaluation category. NOTE: The percentile ranks are valid only within the individual evaluation category and are intended solely for reference and comparison. . Evaluation Category Hydrology: runoff storage potential. water quality, potential for minimizing damage in downstream areas Biology: quality of habitat. abundance and diversity of plant and animal species Visual: diversity and contrast of wetJand and surrounding vegetation, surrounding landforms Cultural: types of access, proximity to schools/institutions, overall environmental quality Economic: presence of agriculture/peat extraction, 8nadrOmOus or game fish. game birds or mammals of commercial value WETLAND RATING: Rank (by percentile I Sub·basin County-wide 94 98 94 81 96 22 23 35 33 12 Each wetland was assigned one of three possible wetland ratings. The wetland ratings were determined by examining the scores of selected Inventory tasks, specific data or percentile ranks for individual evaluation categories. The .criteria used to assign the wetland ratings are delcrlbed In the Introduction. For each rating a number of specific guidelines for new development in or adjacent to wetlands were prepared.

P:SCB The Soos Creek Basin is located north and east of the Green River in King County. While the southern and eastern portions of the basin are rural, the remainder is a rapidly expanding suburban community. This development pattern has not caused serious environmental damage or flooding, however, due to highly pervious soils, an e"tensive network of streams and wetlands that provide natural storage for stormwater runoff, and the fact that development has only recently accelerated in this basin. Although the overall severity of problems in the Soos Creek Basin was not great at the time of reconnaissance, several significant problems were identified and should be addressed. These include bank failures, channel erosion, flooding in SOme locations, and poor stream babitaL Recommendations to address these problems include efforts to 1) inform appropriate agencies of the reconnaissance findings, 2) reevaluate specific: policy issues regarding the managetDClIt of surface water, 3) prepare a comprebensive basin plan, 4) construct the capital improvemCllt projects evaluated witb clUzen advisory committee criteria, and 5) maintain or c:nbancc babitat throUghout the basin. INI'RODUCTION: History and Goals of the Program In 1985 the King County Council approved funding for the Planning Division (now called the Natural Resources and Parks Division), in coordination with the Surface Water Management Division, to conduct a reconnaissance of 29 major drainage basins located in King County. The effort began with an initial investigation of three basins -Evans, Soos, and Hylebos Creeks -in order to determine existing and potential surface water problems and to recommend action to mitigate and prevent tbese problems. These initial investigations used available data and new field observations to examine geology, hydrology, and babitat conditions in eacb basin. Findings from these three basins led the King County Council to adopt Resolution 6018 in April 1986, calling for reconnaissance to be completed on the remaining 26 basins. The Basin Reconnaissance PrograD!, which was subsequently established, is now an important element of surface water management. The goals of the program are to provide useful data "'itb regard to i) critical problems needing immediate solutions, 2) basin characteristics for use in the preparation of detailed basin management plans, and 3) capital costs associated ",ith the early resolution of drainage problems. The reconnaissance repons are intended to provide an evaluation of present drainage conditions in the County in order to transmit information to policymakers to aid them in developing more detailed regulatory measures and specific capital improvement plans. They are not intended to ascribe in any conclusive manner the causes of drainage or erosion problems; instead, they are to be used as initial surveys from which choices for subsequent detailed engineering and other professional environmental analyses may be made. Due to the limited amount of time available for the field work in each basin, the reports must be viewed as descriptive environmental narratives rather than as final engineering conclusions. Recommendations contained in each report provide a description of potential mitigative measures for each panicular basin; these measures might provide maximum environmental protection through capital project construction or development approval conditions. The appropriate e~"lent of such measures will be decided on a case-by-case basis by County officials responsible for reviev.ing applications for permit approvals and for choosing among competing projects for public construction. Nothing in the reports is intended to substitute 1 • , , \ Socs Creek Basin (continued) for a more thorough environmental and engineering analysis possible on a site-specific basis for any proposal. m. FINDINGS IN SOOS CREEK. BASIN P:SCB Reconnaissance in the Soos Creek Basin was conducted in November 1985 by Ray Heller, resource planner, Randall Parsons, engineer; and Don Spencer and John Bethel, consulting soil scientists-Their findings and recommendations are presented as follows_ A Overview of Soos Creek Basin Geographic and land use features. The Soos Creek Basin is located north and east of the Green River in the eastern portion of the Soos Creek Plateau Community Planning Area. The basin is situated east of the city of Kent, northeast of Auburn, and souTheast of Renton. The city of Seattle's Lake Youngs watershed is included in the Soos Creek Basin. The south and east portions of the basin are rural in character, ",th the north and west portions committed to a suburban development pattern that includes subdivisions and scattered single-family homes. The 1985 King County Comprehensive Plan shows areas east of Big Socs Creek (in the northern part of the basin) and south of Lake Youngs with "rural development" designations that specify 1-5 dwelling units (DU) per acre. The southern area to the east of Socs Creek and north of the Green River is designated "transitional." This interim designation will limit development to rural- residential densities until such time as rural/urban designations are made through updated community plans. The King County Parks Department owns more than a five-mile stretch from Southeast 192nd Street to Lake Meridian. along Big Soos Creek. These presently undeveloped park lands are mostly w:tlands and lie ""thin the loo-year floodplain. Major geologic, hydr.ndic, and hydrologic features. The Soos Creek drainage area is a tributary basin to the Green River basin. The area is part of the Puget Sound lowlands and is characterized by a glacial drift plain, covered by small ridges and rounded hills that were formed by continental' glaciation. While the Socs Creek Basin is moderately developed, the degree and amount of channel erosion. slope failures, and other forms of geologic and hydraulic damage are far less than might be e:q"'cted. Artificial conveyances are also still functioning in this basin as they were originally designed and intended. These conditions may be ex-plained by three main factors. First, there is a very effective narural retention and detention (RID) system provided by an extensive network of 52 wetlands and numerous major and minor streams-Most of the wetlands are located in the northern portion of the basin in the upland areas as well as adjacent to streams. Big Socs Creek originates in the northeast comer of the plateau and nows southeast to the junction of Liltle Soos and Jenkins Creeks, then curves west at its confluence "ith Covington Creek. Big Soos Creek joins the Green River east of Auburn near State Road (SR) 18 at 160th Avenue SE. These wetlands and streams {.'! appear to be functioning well as stormwater control facilities for the current levels of 'O;J development, as well as se",ing to prevent damage from surface water runoff. 2 • ( P:SCB B. Soos Creek Basin (continued) Second, the soils in the upland areas generally have a high infiltrative capacity, particularly in the southern portion of the basin. Stormwater is absorbed into the ground at these locations before it can cause erosion or other damage. Third, development in the basin has only just begun. Properly functioning wetlands and streams have not yet been altered, nor have well-draining soils been covered by impervious surfaces to any great extent. Maintaining these properly functioning drainage systems should be a goal in this basin and will be the focus of recommendations made later in the report. Habitat characteristics. The habitat of Soos Creek Basin is generally good and supports large populations of both native and hatchery anadromous fish. The source of the hatchery fish is a State facility near the mouth of Soos Creek. Cutthroat trout reside in stream waters, and anadromous rJSh spawn and travel in many of the tnbutaries and the main stem of Big Soos, according to field observations and reports from local residents at the time of reconnaissance. Habitat is being damaged or threatened in some places by bank erosion and degraded water quality associated "ith land clearing, livestock feces, and wetland filling for development. One of the more serious instances of habitat-threatening erosion originates at the parking lot of the Seattle International Raceway (SIR), which is located on the plateau in the lower portion of the basin. Drainage from the paved parking lot is increasing erosion in nearby tributaries and filling spawning gravelS with sediment. Appendix C of this report identifies sites of habitat damage or potential damage. Further water quality information related to habitat in the basin can be found in the Critical Stream Inventorv of Soos Creek, published by Metro. Effects of Urbanization Low levels of development in most parts of the Soos Creek Basin, together "'ith a well-functioning natural drainage system, have kept serious erosion, sedimentation, and habitat damage to a minimum until now. However, the present and projected rates of development indicate that there could be increasing amounts of damage, as suggested by the types of problems observed during reconnaissance_ The expansion of impervious surfaces in the basin is already beginning to accelerate the rates and volumes of stormwater flowing into (and reducing the capacities of) both natural and artificial channels. Impervious surfaces are also reducing the amount of highly pervious soils available to absorb runoff. The predictable impacts are already in evidence: erosion, mass-wasting, sedimentation, and degraded water quality and other habitat destruction. The following section provides a more detailed account of problems found during field investigation. c. Specific Problems IdentirIed The study team examined numerous sites along the main stem of Big Soos, Little Soos, and West Soos Creeks, as well as 21 small drainages tributary to these main stems. Several of the most significant problems found during reconnaissance are described below. 3 • \ Soos Creek Basin (continued) 1. Bank failures. On Tributary 0072A, river mile .30, for example, there exists a major bank failure triggered by bank undercutting. The source of the problem appears to be increased runoff from street construction. Unless flows are intercepted and redirected to storm sewers or other facilities, there "ill be increased bank erosion and consequential deterioration of property and stream habitat. 2. Channel Erosion. This includes both instream and bank erosion caused by large volumes of runoff emerging from storm drains and washing away highly erodible soils. This creates a new, deeply incised channel that enlarges over time. One example of this problem occurs on Tributary 0072 near the SIR in the lower pan of the basin. Large expanses of pavement at this location have contributed to high volume flows and channel erosion. 3. Floodiog and potential flood~ In numerous locations, development has increased the amount of runoff entering existing drainage facilities or otherwise impeded the ability of natural systems to carry the amount of runoff. When drainage systems Cail to function as they were intended, flooding can OCCUr. Increased development ",;thout concurrent increases in drainage Cacilities adds to the possibility that serious flooding ",;11 occur. On Tributary 0092, river mile 1.20, Cor example (collection point 11), the little Saos has been contained and manicured as it passes through a developed plat. Such alteration to a natural drainage channel reduces the stream's capacity in places. The result has been the regular semi .... nnual flooding of some homes. Funher development could aggravate these kinds of flooding problems. 4. Poor stream habitat due to: a. Lact of <Mlrhead canopy and streamside vegetation. Overhead canopy stabilizes water temperature, while streamside vegetation protects banks from erosion. b. Contamination by livestock feces. In areas of the basin where livestock have extensive access to streams, water quality has become degraded by animal feces. These cause harmful nutrients to be added to the water which can '.. threaten [ISh survival Co Erosion. Streambank and channel erosion, already descnbed above, is caused in pan by livestock access. On Tributary 0073, river miles 3.604.70, for example, there exists poor stream habitat because livestOCk have trampled and denuded banks of vegetation; this has led to the sedimentation of spawning areas and caused turbidity. IV. RECOMMENDATIONS FOR ACTION P:SCB The fol/o"';ng recommendations are based on findings oC the field team and reflect the original goals oC the Basin Reconnaissance Program, as outlined in the introduction of this repon. A. Inform appropriate governmental agencies oC the detailed findings from the reconnaissance of this basin. Project representatives should meet ",ilh staff from King ;' ').' J ( P;SCB Soos Creek Basin (continued) County Roads Division, Surface Water Management Division, Building and Land Development, and other interested agencies to transmit relevant information. B. Reevaluate specifIC policy issues regarding SUIface water management. These may include the need to: 1. Improve enforcement of wetlands regulations to maintain these areas in their natural Slates. This will insure their continued function as surface water quality and quantity controllers, as well as preserve their habitat value. If regulation proves ineffective, the County should secure easements Or consider other means to preserve wetland areas. 2 Require the establishment of undisturbed buffers and setbacks adjacent to natural drainage swales. Variations in stream morphology and geology indicate the need for stream corridor guidelines that take these into consideration. Improve enforcement of "no 'clearing" covenants in these sensitive areas or seek County easements or actual m>l1ership. Fencing along streams in livestock areas would help water quality and reduce erosion and sedimentation. 3. Investigate and promote the inilitration of surface water where feasible and economical to reduce increased runoff from developed areas. Also, encourage the use of grass swales and open ditch conveyance systems to improve infiltration and water quality enhancement capacity. Areas of high filtration are identified on final display maps (for the Basin Reconnaissance Program) in the offices of Surface Water Management, Building and Land Development, and Basin Planning. 4. Requin: the tightlining of storm-drainage outCaI/s down steep or sensitive slopes using state-of·the-art facilities, including high density polyethylene pipe ",ith energy diSSipation at the outfall. 5. Reevaluate stormwater rate and wJume release regulations for new developments. Current regulations may be inadequate and result in unacceptable dm>l1stream erosion that causes property damage and loss of habitat. 6. Inctease current maintenani:e levels for King County surface water RID and conveyance facilities. Due to the lack of funding. maintenance of existing facilities is sometimes insufficient and results in facility dysfunction and failure. These "'ill only be aggravated by additional upstream development. 5 • P:SCB Soos Creek Basin (continued) C. Prepare a comprebensive basin plan to consider, at a minimum, Ibe need to: 1. Enhance and utilize the extensive existing wetlands as regional stol1l1..<Jetention faci1ities v.ithout jeopardizing habitat values. Prepare a schedule for the anticipated need for these hydrologic enhancements as they relate to projected development in the basin and impact the wetland ecology. 2 Enmine existing stol1l1..<Jetention and conveyance facilities to detel1l1ine whether their control orifices are properly sized to optimize the detention site and achieve the maximum benefit to the downstream systems. 3. Establisb floodplains in low.lying areas of slight gradient for existing and developed runoff conditions, i.e., adjacent to wetlands, particularly for wetlands proposed as regional detention sites where inundation of adjacent properties may be significant. 4. Identify stream reaches critical to Ibe maintenance of anadromous and trout populations. 5. Review geologic rmdings from this study in order to identify areas of particular soils' sensitivity and develop special analysis critena for new developments. D. CoIISttuct Ibe capital improvement projects acamIing to the CIP priority selection criteria. These projects, identified in Appendix B of Ibis report, indude projects to: 1 Cahbrnte and retrofit existing detention-control structures and to improve existing conveyance systems. 2 Stabilize channels and slopes. 3. Provide regiooal detention faci1ities, including the utilization of wetlands, where biological assessment has determined that tbe natural habitat values "'ill not be significantly altered. E. Maintain or enhance the instteam and riparian babitals. 1. Maintain wetlands and buffer areas around them. These provide both valuable ",ildlife habitat and natural stonnwater storage that helps to maintain year·round baseflO"-"S in the stream. 2 Adopt a stream-<Xlmdor policy in the Soos Creek Community Plan to protect the stream corridor from damaging types of land uses in adjacent areas. 3. Eocourage Ibe Washington State Department of FISheries to aUow use of Ibe naturaJ stream system for salmon spawning. Maintain a natural run of all the indigenous anadromous species. 4. Prohibit rtlling in Ibe tOO-year floodplain. The County should establish regulations to prevent the loss of floodplains in order to maintain their natural storage for floodwaters and guard against degradation of important fish and ",ildlife habitat. 6 " i-Ii -.- 'C SOOS CREEK BASIN ..... •••••• ® - Basin Boundary Collection Point Boundary Collection Point Stream Tributary Number Proposed Project ~ ...... ~ 1 mi • : .-•• .. • • • .,.

",..,JI ( APPENDIX B CAPITAL IMPROVEMENT PROJECT RANKING SOOS CREEK BASIN Prior to the Soos Creek watershed field reconnaissance, 13 projects had been identified and rated using the CIP selection criteria developed by the Surface Water Management (SWM) Division and the Natural Resources and Parks Division. Following the reconnaissance, 20 projects remain proposed for this area. They include the 7 new, previously unidentified and unrated projects plus the initial 13 projects. The previous SWM capital improvements project ~st for the Soos Creek Basin had an estimated cost of S3,450,000, while the revised list decreases to an estimated cost of S2,622,000. This 24% reduction in estimated capital costs is due mainly to downward revised cost figures for acquiring or securing easements over wetlands. The follm.ing table summarizes the scores and costs for the aps proposed for the Hylebos Creek Basin. The projects were rated aCCOrding to previously established SWM Program Citizen Advisory Committee criteria. The projects ranked below are those for which the first rating question, ELEMENT 1: "GOINO-GO; could be answered affirmatively. The projects can now be considered for merging into the "live" crp Jist. Any project scoring over 100 points should be considered for incorporation into the six-year crp plans.

In addition. the subject property drains to an on-site closed depression. Based on a review of the drainage complaints in the downstream drainage course. there are no existing constrictions or lack of capacity in the existing drainage system. Nor did the field reconnaissance find any potential restrictions of lack of capacity in the existing drainage system downstream from the site. 3.1 Conveyance System Nuisance Problems (Type 1) 3.2 3.3 Conveyance system nuisance problems. in general. are defined as any existing or predicted flooding or erosion that does not constitute a severe flooding or erosion problem. Conveyance system nuisance problems are defined as flooding or erosion that results in the overflow of the constructed conveyance system for runoff events less than or equal to a lO-year event. Examples include inundation of a shoulder or lane of a roadway. Overflows collecting in yards or pastures. shallow flows across driveways. minor flooding in crawlspaces of unheated garages/outbuildings and minor erosion. Based on a review of the drainage complaints provided by King County. there is no evidence of past conveyance system nuisance problems occurring nor is there any evidence of any occurring during our site visit. However. property owners to the south of the project site have indicated that during peak storm events the on-site closed depression does backup through the site onto their property south of the site. almost to their access road to property further to the east and this is all prior to the on-site closed depression overtopping the S.E. Petrovitsky Road right-of-way over the sidewalk and into the conveyance system of S.E. Petrovitsky Road. Severe Erosion Problems (Type 2) Severe erosion problems are defined as downstream channels. ravines. or slopes with evidence of or potential for erosion/incision. sufficient to pose a sedimentation hazard to downstream conveyance systems or propose a landslide hazard by undercutting adjacent slopes. Severe erosion problems do not include roadway or minor ditch erosion. Based on our site visit and the King County drainage complaints. there is no evidence of or potential for erosion/incision sufficient to pose a sedimentation hazard to the downstream conveyance systems evident anywhere along the downstream drainage course. Severe Flooding Problems (Type 3) Severe flooding problems can be caused by conveyance system overflows or the elevated water surfaces of ponds. lakes. wetlands. or closed depressions. Severe flooding problems are defined as follows: • Flooding of the finished area of a habitable building for runoff events less than or equal to the lOO-year event. Examples include flooding of finished floors of homes and commercial or industrial buildings. Flooding in electrical/heating systems and components in the crawlspace or garage of a home. Such problems are referred to as "severe building flooding problems." llOll.OOl.doc [IPlldm] Flooding over all lanes of a roadway or severely impacting a sole access driveway for runoff events less than or equal to the IOO-year event. Such problems are referred to as "severe roadway flooding problems." As mentioned previously, there is no evidence of flooding from the drainage complaints or from our site visit downstream of the subject property. However, the downstream drainage course is in a streambed and there is a 100-year Floodplain Map by the Federal Emergency Management Agency of Soos Creek with potential flooding during the IOO-year stonn event all along the streambed course downstream from the subject property. Most of the area surrounding the downstream drainage course is developed property with single-family residence and condominiums, etc., located all throughout the area. The downstream drainage course does flow through a large wetland area comprising over 100 acres, which is all forested and will remain that way after development of this project site. Almost the entire drainage course consists of following Soos Creek. The portion of the downstream drainage course investigated by the site visit and a review of the soils map indicates that the downstream drainage course occurs through Alderwood, Seattle muck, and Everett-type soils, all of which are till-type soils, except for the Everett, which is an outwash-type soil that is just a small portion of the downstream drainage course. The field reconnaissance for the off-site analysis drainage report was conducted on May 14,2003. It was raining slightly at the time and the skies were overcast. The high temperature on this date was approximately 55 to 60 degrees. 11011.00l.doc [JPJldm] TASK 4 DRAINAGE SYSTEM DESCRIPTION AND PROBLEM DESCRIPTIONS TASK 4 DRAINAGE SYSTEM DESCRIPTION AND PROBLEM DESCRIPTIONS Runoff leaves the site either by sheetflowing off the north property line of the site after overtopping the closed depression, or else sheetflowing off the east property line of the site immediately into the same downstream drainage course, although a little further downstream from the previously mentioned overflow. The vast majority of the runoff leaves the site at the north property line after overtopping the closed depression where it flows into the right-of-way of S.B. Petrovitsky Road and enters a pipe conveyance system for approximately 200 feet until discharging into a manhole where runoff is collected and conveyed underneath S.E. Petrovitsky Road and discharged on the south side of S.E. Petrovitsky Road, immediately into Soos Creek. Runoff then courses south for the most part, passing through an 18-inch RCP culvert under an access road and continuing easterly through thick vegetation, forestland, and wetland areas passing through another culvert under 122nd Place S.E. After that, the runoff enters the large Soos Creek Wetland No.2 where runoff courses southerly all the way to 182nd Street S.B., where it is conveyed underneath the prolongation of that street through twin 42-inch RCP culverts. For a review of all the drainage complaints provided by King County see Exhibit K -Drainage Complaints. There are no complaints concerning low conveyance capacity, flooding, or erosion in the downstream drainage course within a mile of the site. We have investigated the attached complaints that we believe to be near the downstream drainage course based on the complaint list. After review of each complaint there is none that were concerning runoff from the subject property or any other properties concerning low flow conveyance capacity, flooding, or erosion. 1 101 l.OOl.doc [JPJ/dm] EXHIBIT K Drainage Complaints MAY. 8.2003 3:01PM KC WLRD NO.616 P.U5 J/O!/ King County Water and Land Resources (WLR) Division 201 S Jackson Sf, Suite 600 Seattle, WA 98104-3855 FAX To: &tfkM'lcJ/A.vt tiupftwAfA12 Fax: (?{95) ~/~ J'7g:;., Phone: ('-_-'). _____ _ -,::', RE: Levell Analysis Date: Number of pages including cover sheet: 5 From: Cancli McKaI.

The Soos Creek channel on the north side of 11e~ Ave BE between Units c and D on the attached site plan was fairly full with a water level about 3-4 feet below the road level. The debris level along the edge of the ohannel showed that a water level had bean about 1-1.5 foot higher than the exiating level. Based on the slow rotation of the water surface at the south end of the channel, the channel was slowlY draining south ehrough the 2-24inch culverts under 118'· Ave SE. The tennis courts on the south aide of the road were wet and looked as thOugh several feet of water had been ponded there X'ecently. The NW-SE ohannel located just ,BOu,th of the Recreation Suilding was very full and appeared to be draining'Sl!: at the outlet: of the culverts under 118"'. Via phone, I talked 'to Carter On 11-20-01. Sb,'i' said the channel north of ~18~ had flooded to withie about one foot of the top of its banks and about 2 feet of water had ponded in the tennis cOUrts on the south Idde of 118"'. After conferring in our office with Larry Gettle and Mike Malnerich, I called Carter back on 11-28-01 and told her the flooding in the channel and tennis courts were normal for a heavy 3 day X'ainfall with partial plugging of one or more downstream culvert entrances. I thankea her for her complaint and gave her our 206-296-1900 complaint number and the roads 24-bour complaint number at 206-296-8100. The photos I took at the site were not found in my digital camera. ·/(t,:'O" ':'·{r'" , ' : ~,~" ./ r , , J KC WLRD PEiI?:.9 VIT"'5::'k. Y . ..::~" . . ~\.~,.-~~y- , . R.D.,·.

TASKS MITIGATION OF EXISTING AND POTENTIAL PROBLEMS The area downstream of the proposed project known as Petro Vista Plat does not exhibit any potential problems, other than the on-site wetland that is a closed depression, nor is nor is there evidence of any existing problems in this downstream drainage course. Since the 1998 King County, Washington Surface Water Design Manual has indicated that basic water quality and Level 1 Flow Control are the required means of treating and detaining runoff, which meets the requirements of the Soos Creek basin plan as well. However, this project assumes those are inadequate as stated by King County in the previously mentioned letter. This letter requires a Water Quality Menu for the sphagnum bog treatment course to be followed and more restrictive flow control since the site could potentially have an impact on downstream properties. This project will hopefully neither aggravate nor create a problem as specified in the problem specific mitigation set forth in Section 1.2.2.1 of the 1998 King County, Washington Surface Water Design Manual as delineated in Task 4 of this report. A Level 2 or Level 3 off-site analysis should not be required for this project site as there is no evidence of existing or potential problems identified in this Levell analysis other than the on-site closed depression. In addition, the project site is not flat, nor is the downstream drainage course extremely flat. It is fairly constant in slope and the site does not contribute more than 15 percent of the total peak flow drainage downstream from the site. llOll.OOl.doc (JPI/dm] Level 1 Flow Control and Downstream Analysis for Petro Vista Site Development Project FOR: BY: REVISED: JOB NO: Dale VanDerschelden 21308 Snag Island Drive East Sumner, WA 98390 253.891 .1442 LeRoy Surveyors & Engineers, Inc. 1103 Shaw Road Puyallup, WA 98372 253.848.6608 January 13, 2003 6459 ENGINEER: Paul E.

E. Petrovitsky Road in Section 33, Township 23 N, Range 5 E, W.M. in Renton, King County, Washington. The property consists of King County Parcels 6196600380 and 6196600381. It is bordered to the north by S.E. Petrovitsky Road (S.E. 176th St.), to the west by 118th Ave. S.E., and to the east by a BPA power line right-of-way. The site vicinity map is shown in Exhibit "A". Project Description The property owners are proposing to develop and subdivide the 3.83-acre property into 23 single-family residential lots, 1 private park (Tracts A), 2 wetland and buffer tracts (Tracts B and D), a storm drainage tract (Tract C), and associated road and stormwater facilities. The proposed site plan is shown in Exhibit "B". Site Description Soil Type The soils on the property are mapped as Alderwood gravelly sandy loam, 6-15% slopes (upland areas) and Norma sandy loam, 0-2% slopes (wetland areas), by the Soil Conservation Service (U.S. Department of Agriculture, 1973). These types of soil are classified as till soil. The soil types have been confirmed by site visits. Topography The topological data in the development site were collected by LeRoy Surveyors and Engineers, Inc. The site is in a moderate relief terrain. The southwest corner has the highest elevation and the land generally slopes down towards the northeast. A relatively deep depression exists in the north center of the property. This depression contains a small (approximately 0.12 acre) Class 2 Wetland. Existing Ground Cover The land cover information is based on orthophoto image analysis and site visit. There is an office building, a garage, a shed and an equipment yard located on the eastern half of the property. There are some open grassy areas in the northwest and middle south. The rest of the site is forested. The upland has areas of Himalayan blackberries (Rubus procerus), mixed young forest dominated by Douglas firs (Pseudotsuga menziesil) and black cottonwoods. The onsite wetland is dominated by Scrub-Shrub vegetation [predominantly red-osier dogwood (Comus sericea)] with a developing forested class [predominantly Oregon ash (Fraxinus latifolia) and black cottonwoods (Populus balsamifera)]. The low land near eastern border is dominated by black cottonwoods with an understory dominated by trailing blackberries (Rubus ursin us) and snowberries (Symphoricarpos albus). Flow Control and Downstream Analysis 3 Flow Quantity Control Analysis The development site is designated as Level 1 flow control area. The performance criterion is to match the developed peak discharge rates to the predeveloped peak discharge rates for 2-and 10-year return period. Predeveloped Drainage Delineation The whole drainage area for the development site is 4.38 acres, including 0.55 acre of upstream offsite area to the north and west of the property. Much of the onsite and offsite runoff is collected in the onsite depression (onsite wetland). The eastern portion (1.35 areas) of the site (bypass area) drains directly to an offsite wetland to the east. When the onsite depression overflows, the water would run north over the sidewalk along south side of Petrovitsky Road into catchbasins in Petrovitsky Road. The stormwater entering the closed pipe system would travel east for approximately 160 feet and discharge to the off-site wetland east of the property site. The drainage delineation maps are shown in Exhibit "C". The tributary area of the onsite depression is 3.04 acres, consisting of 2.54 acres forest, 0.20 acre grass land, 0.18 acre impervious area (0.11 acre from offsite road 118th Ave. SE.), and 0.12 acre saturated wetland. The bypass area consists of 1.29 acre forest and 0.06 acre impervious area from on site building and driveway (Table 1). Developed Drainage Delineation The developed drainage covers the same area as predeveloped drainage and can be divided into three sub-drainages. The land cover data are based on proposed site plan, assuming each lot has 2100 sq It roof and driveway area. The detention pond has a tributary area of 2.13 acres, including all impervious areas (roofs, driveways, road and sidewalks, total 1.75 acre), and part of landscaped areas (0.28 acre). The pond surface area is 0.09 acre. Runoff from detention pond drainage will be collected by roadside catch basins and conveyed to the detention pond before releasing into the onsite depression through an outlet control structure and a dispersal trench. The on site depression in Tract B (wetland and buffer) will remain in predeveloped conditions and receive sheet flow from Tract A and backyards of Lots 21 -23. Its direct tributary area is 1.26 acre. The bypass area that drains directly to the offsite wetland to the east will be reduced to 0.99 acre, part of which (Tract D within 65-ft buffer) will stay in predeveloped condition. The drainage delineation maps are shown in Exhibit "C", and land cover data are shown in Table 1. Flow Control and Downstream Analysis 4 Table 1.

The results also show that even though the bypass area will be reduced after development, the direct bypass runoff to offsite wetland will increase slightly due to altered land cover. To compensate the increased bypass runoff, the detention pond needs to be configured so that the discharge rates from the onsite depression will be less than the release rates under predeveloped conditions. The targeted release rates at the outlet of the onsite depression are 0.104, 0.172, and 0.254 cfs, respectively for 2-yr, 1 O-yr and 1 OO-yr storm events. Detention Pond Sizing The design of the detention pond is a trial and error process, as the targeted release rates cannot be explicitly set at the pond outlet. The targeted release rates at the outlet of onsite depression are influenced by both direct runoff to the depression and the discharge from the detention pond. It was determined that a pond with following configuration is capable of attenuating the discharge to an extent that will satisfy the flow control requirement at the point of compliance.

So, the requirements flow quantity control are met. Flow Control and Downstream Analysis 13 Runoff Quality Control A wetpond will be constructed under the detention pond to treat the onsite runoff. The required wetpond volume is determined as follows. Vr = (0.9Ai + 0.25 AtQ + 0.10 Au + 0.01 Ao) X (R/12) = 2814 113 Where Vr is volume of runoff from mean annual storm (cf) Ai is area of impervious surface = 76392 If; A tg is area of till soil covered with grass = 12362 ff; Au is area of till soil covered with forest = 0 If; Ao is area of outwash I soil covered with grass or forest = 0 ft2; R is rainfall from main annual storm = 0.47 inch. Where Vb is required wetpool volume; f is volume factor = 3. The wetpond in actual design has two cell and a total volume of 9020 fe. Table 4. Wetpond volume calculation.

For the purpose of this downstream analysis, an 1113-acre drainage area (291 times as large as the development site) is delineated by setting the downstream point at approximately 0.5 miles from the development site. (Exhibit "0" -Downstream Drainage Delineation Map). Stormwater runoff from the development site will be released, either directly from bypass area or indirectly through offsite conveyance system as described above, to the offsite wetland east of the property site. The offsite wetland is primarily a reed canarygrass meadow (Pha/aris arundinacea), with isolated Scrub-Shrub clusters (predominantly spirea (Spirea doug/ash) and Pacific willow (Salix /ucida)) and a Scrub-Shrub fringe (predominantly Himalayan blackberry and western crabapple (Ma/us tusca)). The majority of the wetland is located in the BPA transmission line R-O-W. The stormwater meanders in a southeasterly direction through the off-site wetland and the BPA R-O-W for approximately 275 feet and exits the offsite wetland through an 18" diameter culvert at the south edge. At this point, it begins to change direction and travels easterly for a£froximately 700 feet to a 36 inch diameter corrugated metal culvert under 122 Avenue. This is where it meets the headwaters of the Big Soos Creek and continues in a southerly direction. The characteristics of downstream flow path are described in Table 5.

Soos Creek Basin Plan This report is a lengthy and comprehensive document that describes the existing conditions in Soos Creek Basin and predicts the potential impacts of future land uses on watershed ecosystem. The report provides recommended plans and alternative solutions to deal with the problems associated with urban development. The problems identified in the upper Soos Creek basin include increased peak flows, flooding and undersized channels and culverts. However, these problems do not appear to occur in the close vicinity of the site or in direct downstream area. Part of the report that is relevant to the upper Soos Creek area is attached as Exhibit "E". Reconnaissance Report No.2, Soos Creek Basin This report was written in 1986 when rapid urban development in this area just began. The report identified some surface water problems in Soos Creek Basin and proposed some drainage improvement projects to mitigate those problems. No specific problem or mitigation project was identified in the close vicinity of the site. The report is attached as Exhibit "F". FEMA Floodplain Map The proposed development site is not within a floodway or a floodplain, while the offsite wetland to the east and a large downstream area along the Big Soos Creek is classified as Zone AE, as indicated by the floodplain map (attached as Exhibit "G"). Sensitive Areas Folio and Wetland Inventorv The following categories of sensitive areas have been reviewed: Coal Mine Hazards, Erosion Hazards, Landslide Hazards, Seismic Hazards, National Wetland Inventory Wetlands, and King County Wetland Survey. None of above- mentioned sensitive areas exist within the development site. A seismic hazards area and a 134-acre King County wetland exist approximately 0.1 mile east of the property. A small NWI wetland exists approximately 0.2 mile downstream to the southeast. An erosion hazards area exists approximately 0.4 mile to the southeast. The sensitive areas folio map is attached as Exhibit "H". Flow Control and Downstream Analysis 17 • Soil Survey Map The soils on the property are mapped as Alderwood gravelly sandy loam, 6-15% slopes by the Soil Conservation Service (U.S. Department of Agriculture, 1973, see Exhibit "I"). The soil types have been confirmed by site visits. Drainage Problem The King County Water and Land Resources Division provided a list of complaints related to drainage problem in the general area of the proposed development site. We have checked the locations of the problems and did not find any problem that had originated from or directly connected to the site. The closest location where flooding problem once occurred was at 118TH Ave SE cross Petrovitsky Road to the north in November 2001. The problem appeared to be caused by partial clogging of one or more downstream culvert entrances and were considered normal for a heavy and extended rainfall. This problem was unrelated to the proposed development site by any means. The complete list of complaints and the original record of above-mentioned complaint are attached as Exhibit "J". Field Inspection of the Site We visited the site on two occasions, February 15, 2000 and February 22, 2000. It was cloudy but dry the first visit to the site. It was raining moderately on the second visit. On both occasions, there was no standing water observed in the on-site wetland. The actual drainage system appeared to match the description in the plan. No obvious nuisance problem could be identified at the site and close downstream area. Conclusions The analysis and review of available information and our field inspection confirm that no drainage problem was identified at discharge point and along a quarter mile of downstream flow path under existing conditions. It also can be concluded that the site development will have no negative impact on downstream hydrology after the development, since the rates of discharge at will be unlikely to exceed the predeveloped flow rate. anticipate that.

This fonnat was chosen to facilitate review and ensure that the ultimate users of the plan will have direct access to discussions of impacts and mitigating measures. Figure 1 shows the organization of this document. The document begins with a; short summary of the basin plan and FEIS. Next, the Current and Future Conditions section summarizes the detailed analyses of surface water issues in the system. This section corresponds to an "Existing Conditions· or "Affected Environment" discussion of a stand-alone FEIS. The Recommended Plan section then identifies the preferred course of watershed management, including a preferred approach for each Identified problem. A discussion of preferred alternatives for area-specific conditions in six regions of the 5005 Creek system is followed by preferred alternatives on a basinwide level. The cost and priority of the preferred alternatives are presented with preferred implementation methods. This section also Includes the opinions of the Soos Creek ,Basin Plan Citizen Advisory Committee. The Alternative Solutions and Impacts section identifies and compares alternative solutions for area-specific problems in six regions of the Soos Creek system, as well as basinwide problems. This section identifies preferred alternatives. Finally, the generalized environmental Impacts of and mitigation for these alternatives, including the No-Action and Preferred Alternatives, are discussed in this section. The Background Infonnatlon and References section documents the relevant elements of the environment for FEIS analysis, the SEPA distribution list for this, document, detailed tables of modeled flows, recommended implementation schedule, costs for land use, regulatory, and programmatiC recommendations, recommendations ranking criteria, and a list of references. Finally, public comments on the DEIS are shown with responses. -vi i i - ( , , ", ! ( SUMMARY OF RECOMMENDED PLAN AND ITS IMPACTS INTRODUCTION ====:===========================s=========================::=:===:==:=:====::=: SUMMARY OF RECOMMENDED PLAN AND ITS IMPACTS I NTRODUCTI ON The Soos Creek Basin Plan was developed under the King County SWM Program. The plan covers the Soos, Jenkins, and Covington Creek Basins in south Ki'ng County (Figure 2). USing field observations, the results ,of past studies, and computer modeling, the. Soos Creek Basin Plan evaluates today's stream flows, erosion, sediment depOSition, stream habitat, and water quality. The plan then predicts how these conditions will change as the predominantly rural Soos Creek area develops to suburban and urban densities. Finally, the plan recommends ways to reduce future resource damage and repair current surface water-related problems. The Soos Creek system exemplifies the difficulty of protecting a natural resource while simultaneously accommodating rapid population growth. Parts of the basin are currently rural and thei r streams are In good or excellent condition. Yet elsewhere, the basin Is experiencing some of the fastest development in King County and displays many of the unintended problems aSSOCiated with that activity. These problems Include flooding, erOSion, sedimentation, destruction of fish habitat, and degraded water quality. The results of this basin plan suggest that such consequences are a virtually Inescapable byproduct of urban growth. Mitigation Imposed on new development, or correction of preexisting conditions, can lessen their impact. Yet stable stream channels, a healthy fishery, and clean water depend on the whole Integrated function of a watershed. From the ground that first receives the, rainfall to the channels that convey It downstream, no element Is extraneous. Mitigation can replace a portion of functions lost when development takes place. But there are no data to suggest that all such functions can be replaced on the scale of a large watershed or even In a small subcatchment. The regional deciSions on growth are therefore decisions on the future of our stream systems and quality of their waters as well: where Is degradation tolerable, how much cost are we willing to accept for at most partial protection, and where are the resources so valuable and unspoiled that their protection should be paramount? This basin plan seeks to provide some of those answers, using a full spectrum of analytiC tools and professional expertise. CONDITIONS IN THE SODS CREEK SYSTEM OVERVIEW Much of the Soos Creek system'currently Is rural and its streams are in relatively good condition, particularly in the Jenkins and Covington Creek ( Basins. However, the Soos Creek area is one of the fastest growing areas In King County. The surface water effects of rapid development have only recently become evident. The SODS Creek system's extensive and relatively undisturbed network of streams, wetlands, lakes, forest cover, and large areas of highly Infiltrative outwash depOSits have up to now masked these effects In most areas. ( -1 - ) ___ ''4!:;;'-''_// '" '" -S?> ~ ," miles • • ) ( C~C=B=C=::Z===C=====:C:===========.====================c=:::::=::::=:==:_:==:=: SUMMARY OF RECOMMENDED PLAN AND ITS IMPACTS CONDITIONS IN THE 5005 CREEK SYSTEM Surface water management in the Soos Cree~ system presents a dual challenge: to reduce the surface water problems associated with suburban growth In the Soos Cree~ Basin to the west, and to preserve the elements of the natural hydrology and habitat in the more easter.ly basins of Jen~ins and Covington Cree~s that are critical to the high quality, biological diversity, an~ productivity of this stream system. Recommendations reflect the differences in development-related impact between these two parts of the system. In the west, the recommendations see~ to correct and avoid the most damaging of those impacts. " In the east, the goal of resource preservation is far more challenging, because the full spectrum of deve10pment impacts i ~."so di ffi cuI t to control. Yet the resource at ri s~ here is of critical value not only in King County but also in the Puget Sound Region as a whole. CONDITIONS Present stream flows cause periodic flooding of three County roads, a" par~ing lot, four houses, and two apartment bul1dlngs. In the future, this flooding will increase in both frequency and severity." Floodplains jn most parts of the system will widen due to increases in pea~ stream flows, predicted to be more than two times larger in some areas. One major erosion site is "a potent1i!l future threat toa" house "and another is undermining a County road. Erosion in two small, steep tributaries contributes to downstream sedimentation, particularly at the Green River Hatchery. As pea~ flows increase in the future, the amount of "sediment eroded a"nd transported in the malnstem of Soos Cree~ is expected to roughly double. Only localized water quality degradation has been observed 1n the Soos Creek system, including high fecal coliform levels 1n Little Soos Cree~ and high" nutrient levels In lakes. Nutrients, sediment, and other pollutants carried by stonnwater runoff could pollute domestiC water supply wells in areas with coarse gravelly soils. In the future, nonpoint pollution of this type Is predicted to become an Increasing threat to the use of the streams for water supply, fish habitat, and recreation. " For its size, the Soos Creek system includes some of the most diverse and abundant salmonld habitat in the southern Puget Sound region. Because of this high-quality habitat and the Washington State Department" of fisheries' Green River Hatchery in lower Big Soos Cree~, the Soos Creek system Is a sign1flcant contributor to the $19 mill ion annual value of the Green River fishery (Grette and SaID, 1986). Even with many examples of excellent habitat; the habitat Is starting to exhibit the systemwide effects of rapid development as well as localized habitat problems. These problems include livestoc~-related bank trampling, wetland filling, channelization, loss 0.1 forested stream corridors, fish passage barriers, dewatering, and damage from high flows and sediment movement. These habitat problems are expected to worsen in the future as both human intrusion into previously undisturbed stream corridors and stonnwater runoff increase. - 3 - ~~~=~==~~:~==================================================================== SUMMARY OF RECOMMENDED PLAN AND ITS IMPACTS RECOMMENDATIONS ===========================================================z=================== RECOMMENDATIONS The basin plan recommends a comprehensive basin management program that will correct significant surface water: problems and provide substantially greater protection for the basin's valuable resources than current County programs. Because no sing I e approach effectively addresses the broad range of surface water issues in the basin, a combination of basin management approaches is recommended, including: • land Use Controls: Establishment of maximum densities of one unit/five acres in some areas to protect significant fish habitat (Figure 3); . • Regulations: Adoption of development controls including: -Establishment of buffers of waterside vegetation to protect streams and wetlands, -Floodplain development and clearing limits, and -Requirements that new developments install improved water quality and stomrwater control facilities; • Education and Incentives: Initiation of education and incentive programs to encourage public participation In stream protection; • Stream Steward: Establishment of a new "Stream Steward" position to conduct education and citizen Involvement programs·, facilitate project Installation, and monitor basin management activities in the Soos Creek Basin; • Enforcement and Penalties: Increase of County Code enforcement and stronger penalties for code violations; • Monitoring and Plan Update: Conduct basin monitoring to evaluate the program's long-term success and Identify changing conditions that require adjustments in basin management. o Projects: Installation of stream improvement projects including: -60 small-scale stream improvement projects, including projects for streambank stabilization and revegetation, fencing of livestock-damaged reaches, Improvement of Instream habitat diversity, removal of fish-passage barriers, and repair of channel alterations; and -thirteen flow and erosion~related projects with appropriate mitigation such as bank revegetation, onsite habitat replacement, and fish passage facili- ties, including: * one regional detention facility to control flooding and erosion on Soosette Creek; * a channel enlargement project to reduce flooding and improve habitat on little Soos Creek; * a project to stabilize an eroding streambank of Big Soos Creek below a County road; - 4 - , . ( SUMMARY OF RECOMMENDED PLAN AND ITS IMPACTS ENVIRONMENTAL IMPACTS OF RECOMMENDED PLAN =============================================================================== * larger or parallel culverts· at SE 240th St., 132nd Ave. SE, SE 269th St., 120th Ave. SE and Petrovltsky Road, and 164th Ave. SE to reduce flooding and improve fish passage; * two flood-channel stabll'ization and protection projects on Upper Big S,oos and the Meridian Valley tributary; * two detailed studies of RID alternatives on the Soosette and Meridian Valley tributaries; * raising of two flood-prone County roads; and * tlghtline pipes to convey all or part of the water down steep eroding slopes at four sites (Figure 4). BASIN PLAN IMPLEMENTATION COST AND SCHEDULE The estimated cost of the recommended projects .1 s $5.4 mill ion. The costs of implementing the plan's 50 other recommendations ranges from $1.3 million for staff and start-up costs In the first year to $478,600 In annual costs for ongoing basin management programs. If the recommendations under the Surface Water Management (SWM) Oivision's responsibility were funded using existing SWM revenues from the basin, plan implementation would span 16 years during which property and resource damage would continue • . '. To shorten the implementation period to five years, a basin-specific surcharge is recommended to be considered during King County Council review of the SWM Program In 1990/91. If this surcharge is adopted, the SWM fee for a Single family residence during the five year implementation period would range from $77 in the first year to $59 for the second through fifth years compared to the current fee of $29 per year. After five years, a permanent $3 increase in the $29 fee could pay for continuing basin management programs. ENVIRONMENTAL IMPACTS OF RECOMMENDEO PLAN NO-ACTION ALTERNATIVE If no action is taken, flows will more than double ,in some reaches and human alteration of the stream system will increase as the basin reaches build-out conditions. These flows will worsen property damage and safety hazards due to flooding and erosion. The predicted consequences of these changes include a doubling of the amount of sediment eroded and transported in the mainstem, decreased beneficial use of water due to degraded water quality, and eventual reduction in fish populations due to aquatic habitat damage. BASIN PLAN IMPACTS In the long term, the watershed management measures in this plan are expected to have substantial positive environmental effects.

Proposals for .low densities,floodplain encroachment limits, onsite RID stan- dards, clearing restrictions, vegetated waterside buffers adjacent to streams and wetlands, increased code enforcement and penalties, and incentives for resource protection would reduce future peak flow increases, and consequently . would reduce erosion and aquatic habitat damage. Limits to livestock access to streams would reduce streambank erOSion, resulting in reduced sedimentation of spawning gravels. Proposed education programs and water quality requi~ements for onsite RID facilities would reduce water quality degradation. resulting in reduced impacts on beneficial uses, including aquatic habitat. Water~quality degradation also would be reduced through aquatic habitat/water quality enhance- ment projects. Increased review of onsite septiC systems in areas with highly infiltrative soils also could reduce the risk of surface and ground water pollu- tion. WATER The proposed regional RID facility and any RID facilities that are recommended after detailed study of alternatives would reduce downstream peak flows and, as a consequence, reduce downstream flooding and erosion. RID facilities in wetlands could improve downstream water quality through· the settlement of sedi- ments and attached pollutants but as a result could degrade water quality in the wetland. These facilities also would create an instream impoundment, affecting sediment deposition patterns and potentially degrading upstream aquatic habitat. . EARTH ·Construction-related erosion and sedimentation would occur during installation of tightline and conveyance pipes, construction of RID facilities, and bank stabilization. Once complete, however, these improvements would reduce channel scour and bank failures by reducing.peak flows or bypassing erodable areas. Regional RID facilities would change sediment transport and deposition patterns which could cause sediment to settle In the impoundment area and to be resuspended periodically and depOSited downstream. PLANTS AND ANIMALS The outlet structures for the proposed Instream RID facility and facilities that are recommended for study may be Impassable to fish during flood events. These structures WOUld. be impassable no more than ten percent of the time during the months of adult salmon migration. These facilities would affect primarily resident fish because the proposed instream ponds are either outSide or at the upper limits of the anadromous zone. The instream detention sites may strand juvenile and adult fish as flood flows recede. Sediment could settle in spawning gravels in impounded·reaches. In wetlands used for RID facilities, the increased water elevation and greater variability may cause a shift in the diversity, numbers, and community structure of plant and animal species. instream habitat may be disrupted temporarily by the nOise, erosion, and acti- vity associated with construction. - 8 - SUMMARY OF RECOMMENDED PLAN AND ITS IMPACTS ENVIRONMENTAL IMPACTS OF RECOMMENDED PLAN =============================================================x================= LAND AND SHORELINE USE Local Increases In floodplain width would occur In Soos Creek Park and on undeveloped land In other areu. Proposed regulatory changes that address these Increases and other proposals to protect stream corridors, maintain lower densities, limit clearing, and protect regionally significant aquatic habitat; areas would limit the opportunity for development in flood-prone areas. Density l1m1tswould reduce the density of land use In substantial areas within the system. These limits apply In some areas deSignated as urban on the .. Comprehensive Plan map and conflict with zoning In some areas. The limits would reduce some landowners' abilities to develop land to higher denSities, and thus may have an economic Impact on these private landowners. Residential areas adjacent to project sites may be disrupted temporarily by construction-related traffic and noise. Ongoing disruption of adjacent areas would occur during facllJty maintenance activities. Shoreline access at some project sites also would be limited. TRANSPORTATION Intermittent congestion of neighborhood streets and arterials may occur during construction of projects. Temporary· traffic disruption may occur during construction of the two road-raising projects, but blockage during flood events would be eliminated. PUBLIC SERVICES AND UTILITIES Regional RID facillties and subbasin-specific onsae RID requirements would Increase the County's maintenance"responslbilities. However, County programs already are establ1shed to maintain existing and new RID facl1lties. Land use and regulatory proposals would require County administration, Including revfew of development proposals, Inspection, and enforcement. -11 - ( ( ,.

CURRENT AND FUTURE CONDITIONS DESCRIPTION OF WATERSHED AREA ~========~======c========================================e=::::=:==:===:::==:== CURRENT AND FUTURE CONDITIONS: . Affected Environment DESCRIPTION OF WATERSHED AREA LOCATION The Soos Creek system lies In south King County. north and east of the Green River and southeast of the City of Renton. Big Soos Creek originates In the northeast corner of the glacially molded upland known as the Covington Drift Plain and jotns the Green River just east of Auburn. Covington and Jenkins Creeks are Its main tributaries. STREAMS The Soos Creek system consists of mainstem Big Soos Creek and some 25 tributaries. The system has over 60 miles of stream and drains an area of approximately 70 square miles (44,800 acres) (Figure 5). All major tributaries In the Soos Creek system have similar physical characteristics. All drain flat to rolling terrain in the upper basin, converging below River Mile (RM) 5.0 of Big Soos Creek. Many reaches of the upper plateau flow through extensive wetlands where pools are deep and velocities slow. The upper sections of Big Soos are characterized by heavily wooded riparian corridors interspersed with pastures and increasing residential development. Below RM 5.0, the gradient Increases sharply as the stream flows through a deep canyon with long riffles and sparse pools. In these lower reaches, Big Soos Creek varies between 30 and 40 feet In channel width. Surface water In the Soos Creek system Is carried largely in natural stream channels, typically with culvert crossings in the basin's upper regions and bridge crossings In the lower. The Soos Creek Basin has no regional retentionl detention (RID) facilities, but there are Individual detention ponds on platted and commercial building sites • .. WETLANDS The wetland system Is quite extensive and Includes all classes of freshwater wetlands--predomlnantly open water, scrub-shrub. and forested, with some emergent marsh, wet meadow. and bogs. The King County Wetland Survey and Basin Reconnaissance Report list over 225 wetlands in the Soos Creek system--a total of 2.076 acres, or about 4.6 percent of the land area in the basin (King County, 1966, 1967a. 1967b). Most wetlands of the Soos Creek system are "rlparlan"--assoclated with streams-- and are located on the flat or gently rolling upper plateau of the watershed. In the Jenkins and Covington Creek BaSins, much of the ~pper plateau Is underlain by varying depths of outwash material over till soils. The water table in this area often is close to the surface. As a result, small pocket wetlands appear where potholes and swales intersect the groundwater table. In the upper Jenkins Creek BaSin, for example. the headwaters of many streams are -13 - CURRENT AND FUTURE CONDITIONS DESCRIPTION OF WATERSHED AREA =====::=:====::::====:======:=========a.:==:=::::::::=.c:=:===:==: ••• :=:======= small, linear wetlands that formed in glacial troughs. As these streams travel toward the mainstem, many disappear into porous gravel deposits, only to reappear as wetland pockets farther downslope. LAKES The lakes of the Soos Creek system--Lake Youngs, Lake Meridian, Shadow Lake, Lake Sawyer, Lake Wilderness, Pipe Lake/Lake Lucerne, Ginder Lake, Ravensdale Lake, and Lake Morton--are used primarily for recreation and aesthetic' enjoyment. Six of them have boat ramps, and County parks lfe on the shores of Lakes Meridiani Sawyer, and Wilderness. CURRENT AND FUTURE LAND USE Overview The north and west portions of the Soos Creek Bastn west of Big Soos Creek have a pattern of urban denSity subdivisions, commercial centers, and scattered single-family homes. The most developed areas are along Kent-Kangley Road and near the western boundary wi th ·Kent and Renton. To the west of Big Soos Creek and south of Kent-Kangley Road, the Soos Creek Basin is predominantly rural, with small farms and scattered residences. The Jenkins and Covington Creek BaSins, in the south and east parts of the Soos Creek system, mainly contain hobby farms and rural residences. Second-growth fore·sts are common. Sand, gravel ,.and clay are mined in the hills east and northeast of BlaCk Diamond, and coal is mined nea'r the northeast corner of Ginder Lake. The major developed areas surround Lakes Wilderness and Pipe/ Lucerne, the communities of Covington and Ravensdale, and the City of Black Diamond. Although much of the Soos Creek area remains rural, its population growth, number of subdivided lots, and permits for residential units show it to be one of the fastest-growing areas in King County. The late 1970s saw increased devel- opment, particularly in the western Soos Creek BaSin, and the effects of urban- ization on surface water are already evident. Greater development promises to exacerbate effects such as increased flows and consequent erOSion, and human alteration of streams and wetlands. Maps: Description and Data Sources The current and future land use maps provided data for computer-ba'sed hydrologic simulations. Current land cover data were taken from aerial photographs, Kroll maps, Sensitive Area'Map Folio (amended in 1987), King County Wetlands Volume II, (1983), U.S.G.S. 1:24,000 quadrangles, Soil Conservation Service maps, field investigations, and other studies. Future land cover data were taken from land use plans of the Cities of Kent and Black Diamond, the 1985 King County Comprehensive Plan, the Soos and Tahoma/Raven Heights Community Plans, current zoning, and other studies.

WATER HYDROLOGY .AND HYDRAULICS Introduction The Soos Creek system is hydrologically complex with many lakes, wetlands, and interactions of surface water with groundwater~ Existing development In the basin ranges from rural to high-denslty,urban. A number of flow-related prob- lems have been associated with this urban development •. Understanding the hydrologic mechanisms b.ehind these problems is the key to solving them and pro- vides the basis for predicting where other surface water problems will occur as development continues. This section discusses th~ hydrology of the Soos Creek system under existing (1985) land use and future build-out condltlonsin the absence of recommended mitigating measures. The relevant runoff mechanisms and factors that affect the Soos Creek Basin are discussed first, followed by a description of the basin hydrology and hydraulics under 1985 land use, the conditions under future bulld- out land use, and a list of specific flow-related problems. Runoff Mechanisms The hydrology of the Soos Creek system was characterized by many field visits, the use of a rainfall/runoff simulation computer model, and a hydraulic computer model. The simulation model used was the Environmental Protection Agency's Hydrologic Simulation Program Fortran (HSPF). HSPF was used to portray the hydrology of the basin under current conditions and examine the effects of build-out conditions on hydrology. The U. S. Anmy Corps of Engineers HEC-2 hydraulic model was used to compute flood plains and detenmine the extent of flooding In flood-prone areas •. Input parameters for the modelS used in this analYSis are outlined In the Soos Creek Basin Calibration Reports (King County, 1987c) and are available upon request from King County. Soils were grouped into three broad categories for hydrologic purposes: outwash, till, and wetlands (see Geology section for a complete discussion of soils). Outwash soils consist of sand and gravel deposits that have high infiltration rates. Rainfall in these areas is quickly absorbed and percolates to the groundwater table. Creeks draining these areas typically intercept the groundwater table and receive most of their flow from groundwater discharge. The response in the creeks after a storm is therefore slow, with the peak flow in the creek often occurring up to several days after a storm. T1Il soils are consolidated, contain large percentages of silt or clay, and have low percolation rates compared to the outwash soils. Only a small fraction of -17 - =:======:===:=======::=::====:=======::==============:========::============:== CURRENT AND FUTURE CONDITIONS WATER ~==::::::=:=:============:=c==:======~==============~=========:==::==::==:=:::= .the infiltrated precipitation reaches the groundwater; the rest moves laterally through the thin surface soil, often re-emerging at the base of hillslopes. This shallow, subsurface, lateral movement of flow is called interflow. Interflow travels to the creek much faster than groundwater but slower than surface runoff. Till soils may become saturated in moderate to large storms and prOduce significant amounts of surface runoff. The peak runoff rate from till: areas is therefore typically much higher than from outwash areas. Wetland soils remain saturated throughout much of the year. Although the runoff from wetland areas is typically constant in the summer, during the wet season they produce si_gn1ficant amounts of surface runoff. Three types of cover were considered in analyzing the hydrology of the Soos Creek system: forest, grass/pasture, and impervious. Runoff from forested areas produces the least amount of surface runoff. Forest cover is most significant in till areas because it breaks up the structure of the till soils .and allows more infiltration to Occur. Interception and evapotranspiration, which influence-autumn, spring, and summer storms the most, is greater in forested areas than in the· other cover categories. GraSs-ed areas produce more surface runoff-than forested areas. Because grass is shallow-rooted, it does not contribute to infiltration as forested cover does. Grassed areas therefore saturate more quickly and produce more overland flow in large storms than forested areas. Impervious areas produce the most surface flow, because the infiltration rate in impervious areas is zero. The combination of forest cover and outwash soil produces the lowest peak flows. with grass-covered outwash producing the next lowest, then forested till. grassed till, and finally impervious cover. Peak flows from wetland soils are variable depending on when the storm occurs. In winter when the wetland soils are saturated, they produce high peaks similar to grassed till areas. In summer the wetlands infiltrate precipitation and the runoff characteristics more closely resemble forested outwash. Receiving creeks, lakes, and wetlands also affect the runoff characteristics from Q given area. These features store flows and release them more slowly, thus reducing the flow peak. The degree to which these flows are reduced depends upon the roughness, slope, size, and shape of the channel. The most- sensitive of these parameters is channel size. Thus wetlands and lakes are typically more effective than a typical stream channel at reducing flow peaks. Hydrology Under 1985 land Use Introduction: Flows from the various tributaries in the Soos Creek system were quantified using the HSPF model. It was desirable to examine the hydrologic response of the basin under as many different storm and low-flow conditions as possible. To do this, the longest suitable rainfall record available was input to the HSPF model. This record was collected at the gage at Seattle-Tacoma International Airport. The length of the record is 38 years, spanning October 1 -18 - t, , CURRENT AND FUTURE CONDITIONS WATER 1948 through September 1986. ,The record contains severa I high-i ntensity storms, as well as several drought years. The land use was held constant at 1985 levels throughout the simulation (F1gur,e 6). Figure 8 shows the results of the simulation run (flows for other intermediate' frequencies are listed in the Background Information and References section). The HSPF model simulates flows at the outlet of each subbasin. Flows have been listed in terms of probability, or flow frequency. For example, in Subcatchment 516, the lOO-year flow is 59 cubic feet per second (cfs). This means that a flow of 59 cfs has a one percent probability of occurring in anyone year. Flow frequencies were computed using a Log-Pearson analysis (Water Resources Council, Bulletin 17a, 1977). General Trends: Flows in the more densely developed areas of the Soos Creek Basin are higher than those 'farther east in the Jenkins and Covington Creek Basins. Areas with the highest flow rates relative to the area draining to them are areas in the western part of the basin where development is heaviest. These areas include: the Meridian Valley Tributary (Subcatchment S8). upstream of Lake Meridian (Subcatchment LM3), and Soosette Creek (Subcatchment ST1-ST5). Natural features that presently attenuate high flows from urbanization include: the wetlands along the main stem of Big Soos Creek (Subcatchments S16, SIS, 513, 511, Sg, and S7), Lake Meridian (Subcatchment LM2), and Soos ~reek Wetland 50 at the outlet of Subcatchments ST4 and ST5. Peak flows from the Jenkins and Covington Creek Basins are much lower than those in the Soos BaSin, primarily due to the undeveloped state of the basin, the numerous lakes and wetlands,'and the large areas of highly infiltrative outwash soil. Jenkins and Covington Creeks respond slowly after a storm event, with a gradual rise and fall in flow typical of a groundwater-dominated basin. Hydrology Under Bulldout Conditions Introduction: The effects of future land use on basin hydrology were examined using the HSPF model. The future land use scenario that was assumed for analy- sis was buildout conditions (Figure 7), defined as the densest use permitted under existing or proposed land use plans and zoning. This analysiS assumed that no human-made flow controls were present. , . Under future 'conditions, flood peaks with a recurrence interval. of two years (the 2-year flow) are predicted to increase up to 3.5 times, with an average increase of 1.8 times over 1985 land use. Peak flows at the IOO-year level have an average increase of 1.5 times over 1985 (Figure 9). A particular flood stage will recur more often, on average, but each event of a given frequency will occupy less time. This corresponds with the notion of "flashy" urban streams. 'There are 1985 flow data for 56 of the 58 subcatchments. Of these, 28 are predicted to have future flows occurring more frequently than every 25 years that equal or exceed the SOO-year flow modeled under current conditions. In the Little 5005 drainage basin (Subcatchments LS4-LSl), the 500-year flows under 1985 land use are predicted to occur on average every other year. -?'I - ====:=::=======================================-===========:._=::::-:=== •• ==:== CURRENT AND FUTURE CONDITIONS WATER =======:::========:====:====:::===:====:=====::=:===::====::===:::===:===::==== Flow Increases Due To Loss of Forest: Figure 10 shows future peak flows. Generally, the subcatchments that change from forested land cover to urban uses on till soils are predicted to have the greatest increases in peak flows. The subcatchments In the upper Soos Creek Basin surrounding Lake Youngs (Subcatchments S14, S12, LS4, and LS3), the area downstream of Shadow Lake In Jenkins Basin (Subcatchments J5 and J4), and the area in the lower Covington Basin (Subcatchment C8) are of this type. Peak flows in some of these areas tripled despite the fact that land use densities are relatively low (one unit per acre or less in most cases). These areas are therefore the most sensitive to increased peak flows caused by. development. Flow Increases Due To Increased Impervious Area: Impervious surfaces are the most influential hydrolog1c parameter in detennining how much flows will increase from existing to future conditions. Incr~ases in peak flows under 1985 land use in the following areas may be attributed to large increases in impervious areas associated with urbanization: Lake Meridian Tributary (Subcatchments LM3, and LMl), Soosette Tributary (Subcatchments ST5, ST4, ST3, ST2, and ST1), South Fork Jenkins Creek (Subcatchments SF3, SF2, and SF1), and Ravensdale Lake (Subcatchment C12). System Effects of Increased Peak Flows: Although flows are expected to increase dramatically in the locations described above, the system-wide effects are not expected to be as severe due to the mitigating effects of natural features in the basin. These features include extensive riparian wetiands, lakes with large volumes, and infiltrative soils. Increased flows will increase the magnitude and frequency of water surface elevation in lakes and wetlands. Because the volumes of the lakes in the Soos Creek Basin are large 'compared to the area draining to them, the fluctuations in water elevation under future land use were found to be small, typically two feet or less. Therefore, frequent flooding of lake-side structures should not be a problem under future land use. The effects of Increased flows due to urbanization will be greater on wetlands. Because· wetlands typically have smaller volumes than lakes, Increased flows will cause greater fluctuations of water depth there than in lakes. This fluctuation can cause changes In plant species, and ultimately result in more open water (see Plants and Animals section for a detailed discussion of wetlands). Other Hydrologic Effects of Increased Impervious Area: Although the HSPF model displays particularly well the peak-flow increases that accompany urbanization, other changes will occur as well. Most significant will be distruption in the groundwater regime, particularly the loss to storm flow of water that used to infiltrate and recharge groundwater reservoirs. In the Jenkins and COVington Bas'ins in particular, where streams, riparian wetlands, and shallow. groundwater form a unifed system, disruption of recharge may have long-term consequences, particularly the lowering of wetland water levels and the reduction of non-storm stream flows. .,. . , ) " CURRENT AND FUTURE CONDITIONS WATER Area-Specific Effects Upper Soos Cree~: Increased flqws from Subcatchments 514, 512, and 510 are attenuated by wetlands located along the malnstem In Subcatchffients S13 and SII. Because the tributaries In these sub catchments flow through deep gullies, flooding Is not expected to be a problem In the future: Further, erosion Is not expected to be rapid because the channels are underlain by till. Pea~ flows In the headwaters of the La~e Meridian Tributary are buffered byLa~e Meridian. ' Although flows downstream of the lake (Subcatchment LMl) are predicted to more than double, the magnitude of flow Is still small compared to the capacity of the channel to convey the flow. There have been reports of 'flooding downstream of the la~e In Subcatchment LMl; however. this Is a result of an Inadequate outlet structure on an onslte detentiOn pond and Is not due to peak flows from upstream. Predicted flow Increases In this tributary are therefore not considered problematiC. Specific flow-related problems In the Upper Soos Basin are as follows (see Figure 11 for locations).

The extensive outwash depOSits and the riparian wetlands along the creek attenuate peak flows such that future flows increase by 50 percent over 1985 levels below· Subcatchment SFl. Instream erosion In this area also Is not expected to be a. factor because of the low channel gradients. Similarly, high flows from Subcatchments JIO and J8 are attenuated by the extensive wetland system along the stream In Subcatchment J7 and therefore are not considered to be problematic.

Flow Increases downstream of Lake Sawyer (Subcatchment C8) are sufficient to contribute to increased erosion in the ravine downstream in Subcatchment C2.

Land use and regulatory solutions, concentrated in the eastern part of the basin to ensure adequate future protection of the high- quality resource there and downstream, are also discussed by subbasin. The second section of the Recommended Plan discusses conditions that occur . throughout the Soos Creek system and recommendations that address them. Basinwide recommendations that have Countywide applicability also are in this section. These basinwide recommendations apply throughout the Soos Creek system unless superseded by area-specific requirements. . AREA-SPECIFIC RECOMMENDATIONS UPPER 5005 BASIN: Big Soos Creek and Its Tributaries North of RH 4.6 Introduction The Upper Soos Creek area is one in tranSition, with urban-related problems in its west and north reaches and rural problems in the east. Big Soos Creek and its seven northern tributaries are low-gradient streams with many riparian wetlands. Big Soos Creek flows through 5005 Creek Park from about RM 7 to 13. The northwestern portions of the upper Soos Creek Basin are developing rapidly and most of the area is expected to develop to urban densities of one unit per acre or more. Surface water problems in this area include flooding and high peak flows, increased future peak flows and flooding, and aquatic habitat damage. Recommendations (Figure 21) Flooding: Flooding of apartments near SE 176th St. and County roads SE 256th St. and 148th Ave. SE occurs. To reduce this flooding, the following projects are recommended: • UPPER SOOS CREEK CHANNEL AND CULVERT IMPROVEMENT (Project 5401a), a conveyance enlargement and culvert improvement project to reduce roadway and apartment flooding. Estimated cost*: $224,000 • .. . • SE 256TH/148TH SE ROAD RAISING (Project 5417), raising of the SE 256th St. bridge and the road elevation at 148th Ave. SE. Estimated cost: $230,000. • MERIDIAN VALLEY CHANNEL AND CULVERT IMPROVEMENT (Projects 5421a/5422), a combination of channel stabilization and culvert enlargement on SE 240th St. near the 132nd Ave. SE intersection. Estimated cost: $455,000. * All project costs are for initial implementation only, and do not include ongoing operation and maintenance costs. -79 - · ... ~ .. .

However,"the damage from increased flows should not be as significant where large lakes, such as Lake Meridian, can store additional runOff. ProJects 5401a, 5417, 5421a/5422, 5409 (see above) wlll be sized to control future flows. In addition to the basinwide recommendations (see Basinwide Reconrnendations section), the following actions are reconrnended to reduce habi- tat damage and these future flow increases: o LAKE YOUNGS FOREST RETENTION (ASl). The approximately B30-acre Lake Youngs Watershed should be'retained in forested land cover. Because no acquisition is possible at this time, ~ing County may benefit from an option to purchase at a later date or other long-term preservation agreement with the City of Seattle. Implementing Document: Interlocal Agreement, King County Open Space Plan, or Soos Creek Conrnunlty Plan. o UPPER 5005 RURAL DENSITIES (AS2). Areas deSignated as rural-residential in the 1985 King County Comprehensive Plan should be retained ln rural den- sities ln the upper Soos Creek Basln from Big Soos Creek east toward the Llttle Soos Basin (Subcatchments 57, 59, 510, 512, and 514). Implementing Document: Soos Creek Conrnunity Plan. o UPPER SOOS REOUCED ONSITE DETENTION STANDARDS (ASJ). In. the Lake Meridian subcatchment (LM2), onsite RID facilities in conjunction with single-family development (seven units/acre or less) may be designed to a reduced 2-year 24-hour detention standard if the releases can be conveyed to the lake without causing flooding or erosion. Implementing Document: King County Surface Water DeSign Manual appendix. Aquatic Habitat Damage: Aquatic habitat has been damaged by channelization, livestock trampling, devegetation, poor water quality, debris dumping, erosion and sedimentation, and removal of large organic debris (logs and stumps). The following projects are recommended to address these problems: o PROJECTS 5450, 5451, 5452, 5453, and 5459, to restore instream habitat diversity. Estimated costs*: $165,000; $10,000; $10,000; $10,000; and $1,250 respectively. * Aquatic habitat and water quality improvement project costs reflect construction costs only. -81 - ==:==:===:==========~=====:====:z============================================== RECOMMENDED PLAN AREA-SPECIFIC RECOMMENDATIONS =============================================================================== • PROJECTS 5454, 5458, 5470, 5471, to limit horse and livestock access to streams.

Discussion The goals in the Upper Soos Creek Basin are to reduce flooding of structures and roads-, retain the Integrity of stream channels, and protect the remaining aquatic habitat. Key to thes.e goals is the reconrnendatlon to retain rural den- sities In the eastern half of the area (Subcatchments 57, 59, 510, 512, and S14) and to preserve the forest cover In the Lake Youn9s watershed. The main resource In the Upper Soos area Is the extensive riparian wetland system along the mainstem. This wetland, considered Important system-wide, currently provides excellent rearing habitat for salmonlds, wildlife habitat, and aesthetic benefits to users of Soos Creek Park. During 1989,the King County Natural Resources and Parks Division completed five projects to remove debriS, provide stonmwater detention, revegetate streambanks, and provide stream viewing areas. These habltat~related projects In and near the park will Improve both the wetland habitat and the quality of water entering this wetland from the east. One additional proje~t, the raising or culvertlng of the SE 216th St. and SE 224th St. roadbeds, was evaluated during basin plan preparation and found. to be Ineffective In remedying local sedimentation of spawning gravels and reducing saturation of trails. Future peak flows entering the mainstem'of Soos from the eastern tributaries are predicted to nearly double, even under the Reconrnended Plan. This Increase In flows Is comparatively high. However, flooding In these tributaries is expected to be minimal since they flow through fairly confined channels with adequate conveyance. Increased stream erosion from these channels and subsequent depOSi- tion in the malnstem wetland,-however, may pose local problems as development progresses. The high flows entering from the eastern tributaries are subsequently buffered by the large storage capacity in the mainstem wetland system, resulting in a small (15 percent) Increase in flows over 1985 land use at the wetland outlet. These increases should not significantly expand floodplains nor harm aquatic habitat in the wetland, although some wetland expansion Is expected. The projects and regulatory solutions proposed In the Upper Soos Creek area reduce flooding frequency at three existing local flooding sites, protect streamside wetlands along the malnstem of Big Soos, improve aquatic habitat, and reduce new development-related problems. . -82 - RECOMMENDED PlAN AREA-SPECIFIC RECOMMENDATIONS ==================~=======================================~==================== Project 5401a will address a local flooding problem In the headwaters of Big Soos Creek by increasing the channel and culvert capacity In the flooded area. Project 5417 will raise ·the ro~d elevation of SE 256th St. above the 25-year floodplain. This project will not appreciably affect flows or floodplain elevations In the creek. Project 5421a/5422 proposes to replace the culvert crossing SE 240th ·St. with a larger capacity culvert and stablize the downstream channel. The project will reduce flooding that currently occurs at a"2-year frequency to a 25-year fre- quency. All -culverts will be replaced to WSDOF standards--for fish passage. Project 5409 proposes to study alternatives to reduce flooding downstream of Clark Lake to SE 240th St. This project should be designed in conjunction with Projects 5421a and 5422. Implementation Table 5 summarizes the Upper Soos Creek Basin recommendations, their costs, and implementation priority. Implementation of recommendations within the jurisdiction of other agencies and King County divisions will be negotiated with these agencies. Cost estimates or schedules will be refined during these negotiations. Recommendations to be implemented by the SWM Division are scheduled according to their rank and the availability of SWM Program revenues -for the Soos Creek area. _ -83 - • :=:============================================================================ RECOMMENDED PLAN AREA-SPECIFIC RECOMMENDATIONS =====================================================================~========= TABLE 5 UPPER SOOS IMPLEMENTATION SUMMARY Agency Initial ID Involv_e-Implemen-Imple- # ment Benefit tation Cost mentation 11 Description 21 31 41 Period 51 ASI Lake Youngs Forest OS 1 10,400 Year 2 AS2 Upper Soos Rural Dens-; PCD -1 0 ongoing 5450 Trib. 0072 Chnl.Reloc.

Alternative solutions for area-specific problems in six regions of the Soos Creek system are in the first section. The second section identifies and compares alternative solutions to basinwide problems. Finally, the generalized environmental impacts of these alternatives are discussed. AREA-SPECIFIC ALTERNATIVES I NTROOUCTI ON The Soos Creek Basin Plan encompasses an area with a diverse range of geologic terrains, aquatic environments, and land use activities. In the western part of the Soos Creek system, rapid urban development has contributed to high flows and consequent flooding, bank erosion, and aquatic habitat problems. In the eastern .... part of the system, which Includes virtually all of the Jenkins and Covington Creeks Basins, low levels of existing development and favorable terrain have resulted In some of the highest quality fish habitat in King County. To address the specific concerns In these diverse areas, this section identifies and compares alternative solutions to problems in six regions of the Soos Cre.ek system. These regions Include (progressing from the headwaters downstream) the Upper Soos, Little Soos, Jenkins, Covington, Soosette, and Lower Soos Basins.

To protect the shopping center and road from unacceptable flooding under future land use conditions, the following actions were considered: • NO ACTION, allow periodic flooding of Meridian Valley Shopping Center and SE 240th St. to continue. • MERIDIAN VALLEY DETENTION AND CULVERT REPLACEMENT (Projects 5421/5422), a regional detention pond, channel stabilization, and culvert enlargement on SE 240th St. near the 132nd Ave. SE intersection.

Estimated cost: $517,000. • CLARK LAKE TRIBUTARY HYDROLOGY STUDY (Project 5409), an engineering study of Tributary 0091A from 132nd Ave. SE to the headwaters to evaluate alternatives for control of flooding on this tributary. To be done in conjunction with design of 5421a/5422. Estimated cost: $20,000. Comparison of Impacts: (See Generalized Impacts of Alternative Solutions section for more detailed impacts.) The Upper Soos Conveyance Alternative (5401a) would effectively reduce local apartment flooding by increasing storm- water conveyance capacity during high flows. The Upper So os Detention Alternative (Project 5401) would also be effective in reducing flooding. However, this alternative could change the wetland's plant and animal species by Changing water le~els and would not have the storage capacity to reduce flows much beyond the apartments. Flooding of SE 256th St. would be effectively reduced by either raising of the road (Project 5417) or upstream detention (Project 5417a). However, detention (Project 5417a) could impact park uses and aquatic habitat by creating more sedimentation resulting in wetland and floodplain expansion. -159 - • =============================================================================== ALTERNATIVE SOLUTIONS AND IMPACTS AREA-SPECIFIC ALTERNATIVES =============================================================================== The Meridian Valley Detention and Culvert Alternative (Project 5421/22) would not have sufficient capacity to adequately reduce flooding and downstream ero- sion. This alternative would effectively reduce flooding of Meridian Valley Shopping Center and SE 240th St. but must be Implemented In combination with downstream bank stabilization and the Clark Lake Study Alternative to reduce downstream erosion and degradation fish habitat. The Soos Creek Wetland 20 Detention' Alternative (Project 5407) would reduce peak stream flows downstream to.SE 240th St. but Is on a tributary that contributes only a small part of the stream flows at the floodllJ9 site. Thus this facility would not be effective In reducing flooding, although It would reduce periodiC high flows for the upper 0.5 mile of Tributary 00916. The Clark Lake Tributary study would be done In conjunction with the design for Projects 5421a/5422. The study'would Identify sources of flooding problems and evaluate solutions to problems observed In the reach between SE 240th St. and the 6ig Soos Creek confluence during the January 9, 1990 stonn. If the No-Action Alternative Is selected for any of the three flooding problems, periodic flooding of an aparlment building, shopping center, and roads would continue. As a result, the use of these facilities would be limited during floods, and property damage and safety hazards would continue. Preferred Alternatives: ,The·Soos Creek Wetland outlet channel Improvements (Project 5401a) is the preferred alternative to the apartment flooding at 174th Ave. SE, because It would effectively reduce, flooding without creating wetland impacts. SE 256th St./148th Ave. SE'Road Raising (Project 5417) is the preferred alternative for reducing flooding of SE 256th St. and 148th Ave. SE. This pro- ject would reduce flooding and have little impact on surrounding wetlands, floodplain elevations, or adjacent park uses. Finally, the Meridian Valley Detention and Culvert Enlargement (Project 5421a/22) and Clark Lake Tributary Hydrology Study (Project 5409) together are the pre- ferred alternative for reducing flooding of the Meridian Valley Shopping 'Center and SE 240th St. This alternative Is preferred because It allows flooding and erosion problems throughout thls reach to be evaluated together, resulting in solutions that reduce flooding and flow-related erosion from the creek's head- waters to its confluence with Big Soos Creek. ' Futu re F1 ows Introduction: Erosion, habitat damage, and more 'frequent flooding are predicted as peak flows Increase more' than two-fold In some areas. Much of these flow increases will result from the removal of forest growing on till salls. Any future loss of the natural storage capacity of wetlands and floodplains will aggravate these problems. However, the damage from increased flows should not be significant below large lakes such as Lake Meridian which store runoff and release It slowly. ' -160 - ( ALTERNATIVE SOLUTIONS AND IMPACTS AREA-SPECIFIC ALTERNATIVES In addition to the basinwide alternatives (see Basinwide Alternatives section), the following actions are considered so that future flooding Is reduced and future flow levels are as close .to today's flows as feasible: • NO ACTION, areas would continue to develop at densities allowed by the King· County Comprehensive Plan, Community Plan, and zoning, as amended In the . future. • CURRENT FLOODING PREFERRED ALTERNATIVES (Projects 5401a, 5409, 5417; and 5421a/22).-The stream Improvement projects considered as solutions to current flooding problems will be designed to function under future land use conditions. • LAKE YOUNGS FOREST RETENTION (AS1). The approx1mately 830 acre Lake Youngs Watershed would be retained In forested land cover. Because no acquisition Is possible at this time, the County may benefit from an option to purchase at. a later date or other long-term preservat10n agreement w1th the City of Seattle. • UPPER SOOS RURAL DENSITIES (AS2). Areas designated as rural-residential In the 1985 King County Comprehensive Plan should be retained In rural densities In the Upper Soos Creek Basin. • UPPER 5005 ONSITE DETENTION STANDARDS (AS3). In the Lake Meridian subcatchment (LM2), onslte R/D facilitles'in new developments with slngle- family densities of seven units/acre or less may be designed to a 2-year detention standard if the water can be conveyed to the lake without causing flooding or erosion. Comparison of Impacts: (See Generalized Impacts of Alternative Solutions section for more detailed Impacts.) Because the Rural DenSity Alternative (AS2) is consistent with the 1985 King County Comprehensive Plan, this alternative would be effective If It prevented future plan amendments to allow higher densities. This alternative (AS2) would be most effective If Implemented In combination with the basinwide clearing limits (BW3 and CW4) (see Basinwide Alternatives section). This alternative would affect about 1,540 acres east of Upper Soos Creek toward the Little Soos Basin. Because of, Lake Meridian's large volume relative to the flows entering It, the basinwide onsite R/D sta'ndards (BW2, see Basinwide Alternatives section) are unnecessarily restrictive compared to the area-specific standard (AS3). Basinwide onsite RID standards also would increase the cost of private development more than the area-specific standards. However, facilities' should not be designed to the 2-year standard if their releases would result in flooding or erOSion before discharge to the lake. Although the Lake Youngs Forest Retention Alternative (AS1) is feasible only for the Lake Youngs Watershed where a large forested headwater area remains in public ownership, it would effectively reduce future flows in a subbasin that is very sensitive to deforestation-related flow increases. -161 - c====~========================================================================= ALTERNATIVE SOLUTIONS AND IMPACTS AREA-SPECIFIC ALTERNATIVES =============================================================================== If the No-Action Alt.ernatlve Is selected, future peak 2-year flows would increase an average of 66 percent over 1985 levels. As a result, flooding of an apartment building, shopping center, and two roads; erosion; and aquatic habitat damage would continue. and likely worsen •. Preferred Alternative: Because no alternative alone can effectively reduce future flows enough to protect stream channels and habitat, and reduce flooding, the Lake Youngs Forest Retention (ASl), Rural Densities (AS2), Current Flooding Preferred Alternatives (Projects 5401a, 5409, 5417, 5421a/22), and Reduc·ed Onsite Detention Standards (AS3) Alternatives together are the preferred alter- native. Under the preferred alternative, average 2-yearpeak flows are pre- dicted to be reduced by 74 percent of the predicted flows under the No-Action Alternative. Aquatic Habitat and Water Quality Introduction: Aquatic habitat has been damaged by channelization, l1vestock trampling, devegetation, poor water quality, debris dumping, erosion and sedimentation, and removal of large organic debris. These observed problems are predicted to continue or worsen due·to development-related increases in flow and human activity. In the future, surface water quality could be degraded by onslte septic systems sited too near reaches with adjacent hl9hly infiltrative soils and shallow groundwater aquifers. In addition to the Basinwide Alternatives, the actions listed below were considered to improve habitat damaged by past human activity and reduce future habitat and water quality problems. Although the listed projects may have alternative design features, these features cannot be evaluated here because only minimal site data are available. As a result, the No-Action Alternative I·s considered the only alternative to the projects. Any required evaluation of the Impacts of alternative design features will be conducted at the time of project design and Implementation. • NO ACTION, Allow aquatic habitat damage from livestock trampling, loss of forested streamside corridors, channel alterations, flOWS, and water quality degradation to remain • • AQUATIC HABITAT IMPROVEMENT. Current Floodln and Future Flow Preferred Alternatives (Projects 5401a, 5409, 5417, 5421a 22, AS1, AS2, and AS3 , these preferred alternatives are designed to reduce flows and thus reduce flow-related habitat damage. The Density Preferred Alternatives (AS1 and AS2) also would reduce habitat damage caused by increased human intrusion into and alteration of riparian areas.

Estimated Costs: $86,500 and $178,000 respectively.- Comparison of Impacts: (See Generalized Impacts of Alternative Solutions section for more detailed Impacts.) Llvestoc~ FenCing Projects (5454, 5458, 5470, and 5471) would restore damaged streamban~s and reduce the potential for fecal coliform contamination of the stream system, but would reduce available grazing area compared to the No:Action Alternative. Projects 5450, 5451, 5452, 5453, and 5459 WOuld improve instream habitat diversity and reduce fish stranding in Soos Cree~ Par~ compared to the No:'Action Alternative, but could result in temporary construction-related turbidity. Projects 5473 and 5474 would improve instream habitat diversity by removing debris from streams. Projects 5460 and 5482 would have temporary construction-related erosion Impacts,-but would restore natural channels and improve water quality In the ---long term compared to the No-Action Alternative. Projects 5466 and 5467 would revegetate streamban~s damaged by past human activity, thus reducing erosion and providing shade and other benefits of vegetation compared to the No-Action Alternative. The Current Flooding and Future Flow Preferred Alternatives (Projects 5401a, 5409, 5417, 5421a/22, AS1, AS2, and AS3) would be designed to reduce current and futu-re flows, and thus reduce flow-related habitat damage compared to the No-Action Alternative. The Density Preferred Alternatives (AS1 and AS2) also would reduce habitat damage caused by Increased human intrusion into and alteration of riparian areas. If the No-Action Alternative is selected, Identified aquatic habitat and water quality problems would continue and li~ely worsen. Aquatic habitat would continue to degrade due to increased flows, gre~ter human alteration of wetlands, stream channels, and riparian corridors, reduced aesthetic value of Soos Cree~ Par~, and continued llvestoc~-related damage. - Prefe-rred Alternat Ive: Jndl vldua lly the aquatic habitat Improvement projects have only local benefits and Impacts, but together they Improve the overall habitat diversity In this subbasin. As a result, all the aquatic habitat Improvement projects are part of the preferred alternative. Control of flows by the Current Flooding and Future Flow Preferred Alternatives (Projects 5401, 5409, 5417, 5421a/22, AS1, AS2, and AS3) is preferred for reducing flow-related habitat damage. Basinwide Preferred Alternattves Except where superseded by the Area-specific Preferred Alternatives, the Basinwide Preferred Alternatives (see Basinwide Alternatives section) also would apply in the Upper Soos Basin. -163 - =====:=:::::::=:::::::=:::=====:=====================:============:==:========= ALTERNATIVE SOLUTIONS AND IMPACTS AREA-SPECIFIC ALTERNATIVES ============:====:===:===================:=======:======================:====:: LITTLE SOOS BASIN: Little Soos Cree~ and Its Tributaries Flooding Introduction: Human alteration of the stream channel and construction in the floodplain has caused almost annual flooding of four to six houses in the lower reaches. To protect these houses and two additional houses from the future 100-year flow, the following projects were considered: 0' NO ACTION, Continued almost annual flooding'of four houses. o LITTLE SOOS CHANNEL AND CULVERT ENLARGEMENT (Project 5416), a channel and culvert enlargement project at RM 0.6 and RM l.p. Estimated cost: $404,000 (Figure 33). o LITTLE SOOS REGIONAL DETENTION POND (Project 5416a), a regional detention . pond on Tributary 0092 at RM 1.6. Estimated cost: $250,000. , o LITTLE 5005 HIGH-FLOW BYPASS (Project 54l6b), an apprOXimately one-mlle-long pipeline to divert high flows to Big Soos Creek. Estimated cost: $2,000,000. o HOUSE PURCHASE (Project 5416c), County purchase of the six houses In the future floodplain. Estimated cost: $800,000. Comparison of Impacts: (See Generalized Impacts of Alternative Solutions section for more detailed impacts.) The regional detention pond (Project 5416a) would be Ineffective in reducing flooding due to Site limitations, providing a 16 percent flow reduction only for future flows below the 2-year flow. The high-flow bypass (Project 5416b) would be effective In reducing flows In Little Soos Creek, but is costly, would transfer flow Increases to Big Soos Creek, and would require extensive right-of-way acquiSition along the stream corridor, disrupting several residences. Purchase of the houses (Project 5416c) would effectively reduce the exposure of reSidents to flooding but may be difficult to implement, Is costly, and would not reduce erosion Qr Improve habitat in ·thls channelized reach. If the No-Action Alternative is selected, the current flooding problems and resulting property damage in this reach would continue and likely worsen. Preferred Alternative: The Little Soos Channel and Culvert Enlargement (Project 5416) is the preferred alternative because it would effectively reduce the flood damage, would cause only localized disruption of land uses and habitat, and is comparatively more cost-eff~ctive. Instream habitat and fish passage restoration is also possible with this alternative. Right-of-way costs would be relatively high. . -164 - Exhibit .oF" Reconnaissance Report No.2 Soos Creek Basin Flow Control and Downstream Analysis 22 l RECONNAISSANCE REPORT NO. 2 SOOS CREEK BASIN JANUARY 1986 Natural Resources and Parks Division and Surface Water Management Division King County, Washington Department of Public Works Don laBelle, Director King County Executive Tim Hill King County Council Audrey Gruger, District 1 Cynthia Sullivan, District 2 Bill Reams, District 3 Lois North, District 4 Ron Sims, District 5 Bruce Laing, District 6 Paul Barden, District 7 Bob Grieve, District 8 Gary Grant, District 9 Parts, Planning and Resources Joe Nagel, Director Surface Water Management Division Joseph J.

SUMMARY The Soos Creek Basin is located north and east of the Green River in King County. While the southern and eastern portions of the basin are rural, the remainder is a rapidly expanding suburban community. This development pattern has not caused serious environmental damage or flooding, however, due to highly pervious soils, an ex1ensive network of streams and wetlands that provide natural storage for stormwater runoff, and the fact that development has only recently accelerated in this basin. Although the overall severity of problems in the Soos Creek Basin was not great at the time of reconnaissance, several significant problems were identified and should be addressed. These include bank faiIun:s, channel erosion, flooding in some locations, and poor stream habitat. Recommendations to address these problems include efforts to 1) inform appropriate a&encies of the reconnaissance findings, 2) m:wiuate specific policy issues regarding the management of surface water, 3) prepan: a compreheosM: basin plan, 4) construct the capital impnwement projects evaluated with citizen advisoty committee criteria, and 5) maintain or enhance habitat throughout the basin. U. INTRODUCI10N: Histoty and Goals of the Program P:SCB In 1985 the King County Council approved funding for the Planning Division (now called the Natural Resources and Parks Division), in coordination with the Surface Water Management Division, to conduct a reconnaissance of 29 major drainage basins located in King County. The effort began with an initial investigation of three basins -Evans. Soos, and Hylebos Creeks -in order to determine existing and potential surface water problems and to recommend action to mitigate and prevent these problems. These initial investigations used available data and new field obsexv3tions to examine geology, hydrology, and habitat conditions in each basin. Findings from these three basins led the King County Council to adopt Resolution 6018 in April 1986, calling for reconnaissance to be completed on the remaining 26 basins. The Basin Reconnaissance Program, which was subsequently established, is now an important element of surface water management. The goals of the program are to provide useful data with regard to 1) critical problems needing immediate solutions, 2) basin characteristics for use in the preparation of detailed basin management plans, and 3) capital costs associated with the early resolution of drainage problems. The reconnaissance reports are intended to provide an evaluation of present drainage conditions in the County in order to transmit information to policymakers to aid them 10 developing more detailed regulatory measures and specific capital improvement plans. They are not intended to ascribe in any conclusive manner the causes of drainage or erosion problems: instead, they are to be used as initial surveys from which choices for subsequent detailed engineering and other profeSSional environmental analyses may be made. Due to the limited amount of time available for the field work in each basin, the reports must be viewed as descriptive environmental narratives rather than as final engineering conclusions. Recommendations contained in each report provide a description of potential mitigative measures for each particular basin; these measures might provide maximum environmental protection through capital project construction or development approval conditions. The appropriate extent of such measures will be decided on a case·by-<:ase basis by County officials responsible for reviewing applications for permit approvals and for choosing among competing projects for public construction. Nothing in [he repons is intended to substitute 1 Soos Creek Basin (continued) for a more thorough environmental and engineering analysis possible on a site.specific basis for any proposal. llL FINDINGS IN SOOS CREEK BASIN P:SCB Reconnaissance in the Soos Creek Basin was conducted in November 1985 by Ray Heller, resource planner; Randall Parsons, engineer; and Don Spencer and John Bethel, consulting soil scientists. Their findings and recommendations are presented as follows. A Ovetview of Soos Creek Basin Geographic and land use fealum!.. The Soos Creek Basin is located north and east of the Green River in the eastern portion of the Soos Creek Plateau Community Planning Area. The basin is situated east of the city of Kent, northeast of Auburn, and southeast of Renton. The city .of Seattle's Lake Youngs watetShed is included in the Soos Creek Basin. The south and east portions of the basin are rural in character, .... ;th the north and west portions committed to a suburban development pattern that includes subdivisions and scattered single·family homes. The 1985 King Countv Comprehensive Plan shows areas east of Big Soos Creek (in the northern part of the basin) and south of Lake Youngs with "rural development" designations that specify 1·5 dwelling units (OU) per acre. The southern area to the east of Soos Creek and north of the Green River is designated "transitional." This interim designation will limit development to rural· residential densities until such time as rural/urban designations are made through updated community plans. The King County Parks Department owns more than a five·mile stretch from Southeast 192nd Street to Lake Meridian, along Big Soos Creek. These presently undeveloped park lands are mostly wetlands and lie "ithin the l00·year floodplain. Majer g=logic, hydraulic, and hydrologic featun:s. The Soos Creek drainage area is a tributary basin to the Green River basin. The area is part of the Puget Sound lowlands and is characterized by a glacial drift plain, covered by small ridges and rounded hills that were formed by continental glaciation. While the Soos Creek Basin is moderately developed, the degree and amount of channel erosion, slope failures, and other forms of geologic and hydraulic damage are far less than might be expected. Artificial conveyances are also still functioning in this basin as they were originally designed and intended. These conditions may be explained by three main factors. First, there is a very effective natural retention and detention (RID) system provided by an extensive nerwork of 52 wetlands and numerous major and minor streams. Most of the wetlands are located in the northern portion of the basin in the upland areas as well as adjacent to Streams. Big Soos Creek originates in the northeast corner of the plateau and flows SQutheast to the junction of Little Soos and Jenkins Creeks, then curves west at its confluence with Covington Creek. Big Soos Creek joins the Green River east of ,'>"uburn near State Road (SR) 18 at 160th Avenue SE. These wetlands and streams appear to be functioning well as stonnwater control facilities for (he current levels of development, as ,veil as serving to prevent damage from surface water runoff. 2 P:SCB Soos Creek Basin (continued) Second, the soils in the upland areas generally have a high infiltrative capacity, particularly in the southern portion of the basin. Stormwater is absorbed into the ground at these locations before it can cause erosion or other damage. Third, development in the basin has only just begun. Properly functioning wetlands and streams have not yet been altered, nor have well-draining soils been covered by impervious surfaces to any great extent. Maintaining these properly functioning drainage systems should be a goal in this basin and will be the focus of recommendations made later in the report. Habitat characteristics. The h~bitat of Soos Creek Basin is generally good and supports large populations of both native and hatchery anadromous fish. The source of the hatchety fish is a State facility near the mouth of Soos Creek. Cutthroat trout reside in stream waters, and anadromous fish SpaV.l1 and travel in many of the tributaries and the main stem of Big Soos, according to field observations and reports from local residents at the time of reconnaissance. Habitat is being damaged or threatened in some places by bank erosion and degraded water quality associated \\.;th land clearing, livestock feces, and wetland filling for development. One of the more serious instances of habitat-threatening erosion originates at the parking lot of the Seattle International Raceway (SIR), which is located on the plateau in the lower portion of the basin. Drainage from the paved parking lot is increasing erosion in nearby tributaries and filling spa\\'l1ing gravels with sediment. Appendix C of this report identifies sites of habitat damage or potential damage. Further water quality information related to habitat in the basin can be found in the Critical Stream Inventorv of Soos Creek, published by Metro. B. Effects of Urbanization Low levels of development in most parts of the Soos Creek Basin, together with a well-functioning natural drainage system, have kept serious erosion, sedimentation, and habitat damage to a minimum until now. However, the present and projected rates of development indicate that there could be increasing amounts of damage, as suggested by the types of problems observed during reconnaissance. The expansion of impervious surfaces in the basin is already beginning to accelerate the rates and volumes of stormwater flowing into (and reducing the capacities of) both natural and anificial channels. Impervious surfaces are also reducing the amount of highly pervious soils available to absorb runoff. The predictable impacts are already. in evidence: erosion, mass-wasting, sedimentation, and degraded water quality and other habitat destruction. The following section provides a more detailed account of problems found during field investigation. c. Specific Problems Identified The study team examined numerous sites along the main stem of Big Soos. Little Soos, and West Saos Creeks. as well as 21 small drainages tributary to these main stems. Several of the most Significant problems found during reconnaissance are described below, 3 Soos Creek Basin (continued) 1. Bank failures. On Tributary 0072A, river mile .30, for example, there exists a major bank failure triggered by bank undercutting. The source of the problem appears to be increased runoff from street construction. Unless flows are intercepted and redirected to storm sewers or other facilities, there will be increased bank erosion and consequential deterioration of propeny and stream habitat. 2 CbaoDeI Erosion. This includes both instream and bank erosion caused by large volumes of runoff emerging from storm drains and washing away highly erodible soils. This creates a new, deeply incised channel that enlarges over time. One example of this problem occurs on Tributary 0072 near the SIR in the lower pan of the basin. Large expanses of pavement at this location have contributed to high volume flows and channel erosion. 3. Flooding and potential flooding. In numerous locations, development has increased the amount of runoff entering existing drainage facilities or otherwise impeded the ability of natural systems to carry the amount of runoff. When drainage systems fail to function as they were intended, flooding can occur. Increased development "ithout concurrent increases in drainage facilities adds to the possibility that serious flooding "ill occur. On Tributary 0092, river mile 1.20, for example (collection point. 11), the Little Soos has been contained and manicured as it passes throuih a developed plat. Such alteration to a natural drainage channel reduces the stream's capacity in places. The result has been the regular semi-annual flooding of some homes. Funher development could aggravate these kinds of flooding problems. 4. Poor stream habitat due to: a Lack or overhead canopy and streamside vegetation. Overhead canopy stabilizes water temperature, while streamside vegetation protects banks from erosion. b. Contamination by livestock feces. In areas of the basin where livestock have e~'tensive access to streams, water quality has become degraded by animal feces. These cause harmful nutrients to be added to the water which can threaten fish survival c. Erosion. Stream bank and channel erosion, already described above, is caused in part by livestock access. On Tributary 0073, river miles 3.60·4.70. for example, there exists poor stream habitat because livestOCk have trampled and denuded banks of vegetation; this has led to the sedimentation of spavlI1ing areas and caused turbidity. IV. RECOMMENDATIONS FOR ACTION P:SCB The following recommendations are based on findings of the field team and reflect the original goals of the Basin Reconnaissance Program, as outlined in the introduction of this report. A Inform appropriate governmental agencies of the detailed findings from 'he reconnaissance of this basin. Project representatives should meet with staff from King Soos Creek Basin (continued) County Roads Division, Surface Water Management Division, Building and Land Development, and other interested agencies to transmit relevant information. B. Reew.luate specUIC policy issues regatding surface water management These may include the need to: L Improve enforcement of wetlands reguJatioos to maintain these areas in their naluJal states. This will insure their continued function as surface water quality and quantity controllers, as well as' preserve their habitat value. If regulation proves ineffective, the County should secure easements or consider other means to preserve wetland areas. 2. Require the establishment of undisturbed buffem and setbacks adjacent to natural drainage swales. Variations in stream morphology and geology indicate the need for stream corridor guidelines that take these into consideration. Improve enforcement of "no clearing" covenants in these sensitive areas or seek County easements or actual "",nership. Fencing along streams in livestock areas would help water quality and reduce erosion and sedimentation. 3. Ilm:stigate and promote the inrtltration of surface water where feasible and economical to reduce increased runoff from developed areas. Also, encourage the use of grass swales and open ditch conveyance systems to improve infiltration and water quality enhancement capacity. Areas of high filtration are identified on final display maps (for the Basin Reconnaissance Program) in the offices of Surface Water Management, Building and Land Development, and Basin Planning. 4. Require the tightlining of storm.<frainage outfalls down steep or sensitive slopes using state-of-the·art facilities, including high density polyethylene pipe with energy dissipation at the outfall. 5. Reevaluate stormwater rate and .oIume release regulations for new developments. Current regulations may be inadequate and result in unacceptable d"""nstream erosion that causes property damage and loss of habitat. 6. Increase current maintenani:e levels for King County surface water RID and conveyance facilities. Due to the lack of funding, maintenance of existing facilities is sometimes insufficient and results in facility dysfunction and failure. These will only be aggravated by additional upstream development. P:SCB 5 P:SCB Soos Creek Basin (continued) c. Prepan: a oomprehellSive basin plan to oonsider, al a minimum, the need 10: L Enhance and utilize the extellSive existing ..etIands as regional storm-detention facilities without jeopardizing habitat values. Prepare a schedule for the anticipated need for these hydrologic enhancements as they relate to projected development in the basin and impact the wetland ecology. 2 Examine e:xistinC storm-detention and comeyance facilities 10 determine whether their control orifices are properly sized to optimize the detention site and achieve the maximum benefit to the downstream systems. 3. Establish Ooodp1ains in low-lying areas of slight cradient for existing and developed runoff conditions,· i.e, adjacent to wetlands, particularly for wetlands proposed as regional detention sites where inundation of adjacent properties may be significant. 4. Identify stream reaches critical to the maintenance of anadromous and trout populations. 5. Review geologic rmdings from lhis study in order to identify areas of particular soils' sensitivity and develop special analysis criteria for new developments. D. Construct the capital impI<M:ment projects according to the CIP priority selection criteria. These projects, identified in Appendix B of this report, include projects to: 1 Calibrate and retrofit existing detention-control structures and to improve existing conveyance systems. 2 Stabilize cbannels and slopes. 3. Provide regional detention facilities, including the utilization of wetlands, where biological assessment has determined that the natural habitat values will not be significantly altered. E. Maintain or 'enhance the instream and riparian habitats. 1. Maintain wetlands and buffer areas around them. These provide both valuable wildlife habitat and natural SlOrmwater storage that helps to maintain year· round baseflows in the stream. 2 Adopt a stream-corridor po~cy in the Soos Creek Community Plan to protect the stream corridor from damaging types of land uses in adjacent areas. 3. Encourage the Washington State Department of FISheries to allow use of the natural stream system for salmon spawning. Maintain a natural run of all the indigenous anadromous species. 4. Prohibit fIlling in the lOO-year floodplain. The County should establish regulations to prevent the loss of floodplains in order to maintain their natural storage for floodwaters ~nd guard against degradation of important fish and wildlife habitat. 6 . !'.' .-. ..

Following the reconnaissance, 20 projects remain proposed for this area. They indude the 7 new, previously unidentified and unrated projects plus the initial 13 projects. The previous.,SWM capital improvements project list for the Soos Creek Basin had an estimated cost of S3,450,000, while the revised list decreases to an estimated cost of $2,622,000. This 24% reduction in estimated capital costs is due mainly to downward revised cost figures for acquiring or securing easements over wetlands. The following table summarizes the scores and costs for the CIPs proposed for the Hylebos Creek Basin. The projects were rated according to previously established SWM Program Citizen Advisory Committee criteria. The projects ranked below are those for which the first rating question, ELEMENT 1: "GO/NO.GO," could be answered affinnatively. The projects can now be considered for merging into the "live" CIP list. Any project scoring over 100 points should be considered for incorporation into the six-year CIP plans. RANK PROJECT NO.

'" COMPLAINT 01-0742 JENNY CARTER at CASCADE p~ CONDOS D96368 11802 SE PETRDVITSKY ROAD Ta 656E7 lnvestigated by ALAN MEYERS 11-15-01 I toured the eite about 1 PM the day after the heavy rains bad ended. The Soos Creek ~el on the north eide of llS'" Ave 5E between Units C and D on the attached site plan was fairly full with a water level about 3-4 feet below the road level. The debris level along the edge of the channel showed that a water level had been about 1-1.5 foot higher than the existing level. ~ased on the slow rotation of the water surface at the south end of the channel, the channel was slowly draining south through the 2-24inch culverts under 11a~ Ave SE. The tennis courts on the south side of the road Were wet and looked as though several feet of water had been ponded there recently. The NW-5E channel located just south of the Recreation Building was very full and appeared to be draining 5E at the outlet of the culverts under 118'". Via phone, I talked to Carter on 11-20-01. She said the channel north of llS~ had flooded to within about one foot of the top of its banks and about 2 feet of water had ponded in the tennis courts on the south side of 119". After confe~ring in our office with Larry Gettle and Mike Malnerich, I called Carter back on 11-28-01 and told her the flooding in the channel and tennis courts were normal for a heavy 3 day rainfall with partial plugging of one or more downstream culvert entrances. I thanked her for her complaint and gave her our 20G-29G-1900 complaint number and the roads 24-hour complaint Dumber at 206-296-9100. The photos I took at the site were not found in my digital camera. 09/13/2002 FRI 08:00 rTX/RX NO 5115] riiJ 003 c •• SEP.13.2002 8:26RM KC WLRD pE-r/ZoVlrSk.

STUDY AREA DEFINITION AND MAPS TASK! STUDY AREA DEFINITION AND MAPS The proposed Petro Vista Plat is approximately 3.83 acres of land located within a portion of Section 33, Township 23 North, Range 5 East, Willamette Meridian, King County, Washington. More particularly, the site is located at 11925 S.E. Petrovitsky Road and is easily viewed on the enclosed Exhibit A - Vicinity Map, which depicts the exact location of the project site. The existing topography of the site has slopes ranging from 2 percent to 30 percent. The site tends to slope towards the north-central portion of the site and runoff collects in a closed depression and wetland area there. The vast majority of the site consists of second growth forest; however, there is a construction company office that is leased along the northeast comer of the site with another metal building behind it. More towards the center portion of the site is a storage yard for constrnction materials adjacent to the metal building. There is also a wetland area along the eastern property boundary of the site. The Bonneville Power Administration (BPA) transmission easement forms the eastern property line of the site. S.E. Petrovitsky Road forms the northern property line and 118th Avenue S.E. forms the eastern property line. An existing residential development zoned R-6 lies south of the site. The wetland area in the north-central portion of the site actually is created by a closed depression where runoff is infiltrated from the upstream basin and on-site basin when it collects there. However, during major storm events the wetland area does fill up and overtop into the S.E. Petrovitsky Road right-of-way. UPSTREAM DRAINAGE ANALYSIS Based on the USGS Quad Map and our site visit, it appears that there is upstream flow onto and through the site. For the most part, areas south of the site and from l18th Avenue S.E. tend to drain onto and through the site. Please see Exhibit C -Upstream Basin Map for a complete overview of the upstream basin contributing runoff to the property. During major storm events this upstream basin may be actually larger in size than what is depicted on the Upstream Basin Map because runoff tends to overtop the right-of-way of 118th Avenue S.E., which conveys runoff in ditches on both sides of the road. Runoff from the west may cross 118th Avenue S.E. and discharge into the subject property as well. The property owner immediately south of the subject property indicated during the site visit that runoff from the npstream basin fills up within the subject property and backs up onto his property, prior to overtopping onto S.E. Petrovitsky Road. 11011.001.doc [JPJ/dm] EXHIBIT A Vicinity Map /WIll OLIva ClKT[IIY n, PI. ~.: :lfti '.1 ·i "'!; '1R[) ,o/;~ '~1 .{ Sl 31'.1 I" IO'IP. ., , 16 RENTON ., ' " 'it> , ,I _~_"_'_!l_. '.

The Basin Reconnaissance Summary Report indicates a project is slated to be constructed in Boulevard Lane Park, which will be to construct a berm and proportional control weir there if the wetlands can maintain their integrity after the construction of the berm and weir. It is not known if this project has been constructed or not; however, it was proposed to help mitigate flow control problems in the upstream basin of Soos Creek. • Critical Drainage Area Maps: According to the Water Quality Applications Map in the 1998 King County, Washington Surface Water Design Manual (KCSWDM), basic water quality treatment is required. According to the Flow Control Applications Map, also in the 1998 KCSWDM, Level 1 Flow Control is required as a minimum. However, in spite of these water quality and flow control applications maps, King County has indicated in a letter dated February 20, 2003, addressed to Robert King of LeRoy Surveyors and Engineers, Inc., tbat for water quality purposes the site drains to Soos Creek Wetland No.2, which is a sphagnum bog wetland that requires a special type of water quality pertinent to sphagnum bog wetlands. In addition, Level I Flow Control is not sufficient to meet the requirements for flow control for this project since it will impact the Tract B wetland with an increase of runoff volume, which will have a deleterious effect on the existing vegetation in the wetlands. • Floodplain and Floodway FEMA Maps: Please see the enclosed Exhibit D -FEMA Map utilized for this analysis. Panel No. 983 of 1,725, Map No. 53033C0983 F, revised May 16, 1995, and as indicated by this map, the proposed project site potentially does lie within the floodplain or flood way of a stream along the eastern property line adjacent to the Soos Creek tributary. Please refer to Exhibit D -FEMA Map. • Other Off-Site Analysis Reports: A review of Exhibit I -Basin Reconnaissance Summary Report and the site investigation were conducted in preparation of this Level 1 Drainage Analysis. The United States Department of Agriculture Soils Conservation Service Map is also provided. See Exhibit F. • Sensitive Areas Folios: Based on a review of the King County Sensitive Areas Map Folios, it was found the subject site does not lie within any sensitive area; however, there are a couple of wetlands on the site and Soos Creek lies immediately east of the site, whose floodplain may impact the site, depending on topographic features. • Road Drainage Problems: This is not applicable. • United States Department of Agriculture King County Soils Survey: Based on the soils map for this area, the entire site is located within Alderwood-type soils, which are known to be till-type soils. • Wetland Inventory Map: The Wetland Inventory Map for this area is included.

WETLAND EVALUATION SUMMARY: 0818 was collected in the five categories shown below. Within each category the data was evaluated to produce numerical values. Composite values for each category were produced in order to compare each wetland to other wetlands in its sub-basin and in King County. The result of ttlat comparison was a percentile rank. The percentile is expressed on 8 scale of one hundred and indicates the percent of wetlands that scored equal to or below that particular site. For example, 8 percentile rank of 80 under sub-basin means that the wetland scored equal to or better than 80 percent of aU sites within the sub-basin for that evaluation category. NOTE: The percentile ranks are valid only within the individual evaluation categOry and are intended solely for reference and comparison. Evaluation Category Hydrology: runoff storage potential, water quality, potential for minimizing damage in downstream areas Biology: quality of habitat, abundance and diversity of plant and animal species Visual: diversity and contrast of wetland and surrounding vegetation, surrounding landforms Cultural: types of access, proximity to schools/institutions, overall environmental quality Economic: presence of agriculture/peat extraction, anadromous or game fish, game birds or mammals of commen::ial value WETLAND RATING: Rank (by percentile) Sub·besin County-wide 94 98 94 81 96 22 2.3 .35 .3.3 12 Each wetland was assigned one of three possible wetland ratings. The wetland ratings were determined by examining the scores of selected Inventory tasks, specific data or percentile ranks for individual evaluation categories. The .criteria used to assign the wetland nltings are described in the Introduction. For each rating a number of specific guidelines for new development In or adjacent to wetlands were prepared. The guidelines are intended to assist in carrying out King County's Sensitive Areas Ordinance and other wetland policies.

TABLE OF CONTENTS L SUMMARY u. P:SCB The Soos Creek Basin is located north and east of the Green River in King County. While the southern and eastern portions of the basin are rural, the remainder is a rapidly expanding suburban community. This development pattern has not caused serious environmental damage or flooding, however, due to highly pervious soils, an ex'!ensive network of streams and wetlands that provide natural storage for stormwater runoff, and the fact that development has only recently accelerated in this basin. Although the overall severity of problems in the Soos Creek Basin was not great at the time of reconnaissance, several significant problems were identified and should be addressed. These include bank failures, channel erosion, flooding in some locations, and poor stream babitat. Recommendations to address these problems include efforts to 1) inform appropriate agencies of the reconnaissance findings, 2) reevaluate specific policy issues regarding tbe managemeot of surface water, 3) prepare a comprehensive basin plan, 4) construct the capital impIOYement projects evaluated with citizen advisory committee criteria, and 5) maintain or enhauce babitat throughout the basin. INIRODUCIlON: History and Goals of the Program In 1985 the King County Council approved funding for the Planning Division (now called the Natural Resources and Parks Division), in coordination with the Surface Water Management Division, to conduct a reconnaissance of 29 major drainage basins located in King County. The effort began with an initial investigation of three basins -Evans, Soos, and Hylebos Creeks -in order to determine existing and potential surface water problems and to recommend action to mitigate and prevent these problems. These initial investigations used available data and new field obsetvations to examine geology, hydrology, and habiTat conditions in each basin. Findings from these three basins led the King County Council to adopt Resolution 6018 in April 1986, calling for reconnaissance to be completed on the remaining 26 basins. The Basin Reconnaissance Progralll, which was subsequently established, is now an important element of surface water management. The goals of the program are to provide useful data "'ith regard to i) critical problems needing immediate solutions, 2) basin characteristics for use in the preparation of detailed basin management plans, and 3) capital costs associated "'ith the early resolution of drainage problems. The reconnaissance reports are intended to provide an evaluation of present drainage conditions in the County in order to transmit information to policymakers to aid them in developing more detailed regulatory measures and specific capital improvement plans. They are not intended to ascribe in any conclusive manner the causes of drainage or erosion problems; instead, they are to be used as initial surveys from which choices for subsequent detailed engineering and other professional environmental analyses may be made. Due to the limited amount of time available for the field work in each basin. the repons must be viewed as deSCriptive environmental narratives rather than as final engineering conclusions. Recommendations contained in each report provide a description of potential mitigative measures for each panicular basin; these measures might provide maximum environmental protection through capital project construction or development approval conditions. The appropriate e>.,ent of such measures "ill be decided on a case·by-<:ase basis by County officials responsible for revie,,;ng applications for permit approvals and for choosing among compeTing projects for public construction. Nothing in the reports is intended to substitute 1 ( Soos Creek Basin (continued) for a more thorough environmental and engineering analysis possible On a site-specific basis for any proposal. III. FINDINGS IN SOOS CREEK BASIN P:SCB Reconnaissance in the Soos Creek Basin w-as conducted in November 1985 by Ray Heller, resource planner; Randall Parsons, engineer; and Don Spencer and John Bethel, consulting soil scientists. Their findings and recommendations are presented as follows. A Overview of Soos Creek Basin Geographic and land use features. The Soos Creek Basin is located north and east of the Green River in the eastern portion of the Soos Creek Plateau Community Planning Area. The basin is situated east of the city oC Kent, northeast oC Auburn, and southeast of Renton. The city of Seattle's Lake Youngs watershed is included in the Soos Creek Basin. The south and east portions of the basin are rural in character, with the north and west portions committed to a suburban development pattern that includes subdivisions and scattered single-family homes. The 1985 King CounlV Comprehensive Plan shows areas east of Big Soos Creek (in the northern part of the basin) and south of Lake Youngs with "rural development" designations that specify 1-5 dwelling units (DU) per acre. The southern area to the east of Soos Creek and north of the Green River is designated "transitional: This interim designation will limit development to rural- residential densities until such time as rural/urban designations are made through updated community plans. The King County Parks Department owns more than a five-mile stretch from Southeast 192nd Street to Lake Meridian, along Big Soos Creek. These presently undeveloped park lands are mostly w~t1ands and lie y,ithin the loo-year floodplain. Major geologie, bydr.ndiC; and hydrologic features. The Soos Creek drainage area is a tributary basin to the Green River basin. The area is part of the Puget Sound lowlands and is characterized by a glacial drift plain, covered by small ridges and rounded hills .that were formed by continental' glaciation. While the Soos Creek Basin is moderately developed, the degree and amount of channel erosion, slope failures, and other forms of geolOgic and hydraulic damage are far less than might be expected. Anifidal conveyances are also still functioning in this basin as they were originally designed and intended. These conditions may be e"plained by three main factors. First, there is a very effective narural retention and detention (RID) system provided by an extensive network of 52 wetlands and numerous major and minor streams. Most of the wetlands are located in the northern portion of the basin in the upland areas as well as adjacent to streams. Big Soos Creek originates in the northeast comer of the plateau and flows southeast to the junction of Little Soos and Jenkins Creeks, then curves west at its confluence 'With Covington Creek. Big Soos Creek joins the Green River east of Auburn near State Road (SR) 18 at 160th Avenue SE. These wetlands and streams ~·l appear to be functioning well as Slormwater control facilities for the current levels of ~ development, as well as solVing to prevent damage from surface water runoff. 2 • ( P:SCB B. Soos Creek Basin (continued) Second, the soils in the upland areas generally have a high infiltrative capacity, particularly in the southern portion of the basin. Stonnwater is absorbed into the ground at these locations before it can cause erosion or other damage. Third, development in the basin has only just begun. Properly functioning wetlands and streams have not yet been altered, nor have well-draining soils been covered by impervious surfaces to any great extent. Maintaining these properly functioning drainage systems should be a goal in this basin and will be the focus of recommendations made later in the report. Habitat cbaracteristics. The habitat of Soos Creek Basin is generally good and supports large populations of both native and hatchery anadromous fish. The source of the hatchery fISh is a State facility near the mouth of Soos Creek. Cutthroat trout reside in stream ",'Sters, and anadromous fISh spawn and travel in many of the tnbutaries and the main stem of Big Soos,-according to field obseIVations and reports from local residents at the time of reconnaissance. Habitat is being damaged or threatened in some places by bank erosion and degraded water quality associated 'With land clearing, livestock feces, and wetland filling for development. One of the more serious instances of habitat-threatening erosion originates at the parking lot of the Seattle International Raceway (SIR), which is located on the plateau in the lower portion of the basin. Drainage from the paved parking lot is increasing erosion in nearby tributaries and filling spawning gravels with sediment. Appendix C of this report identifies sites of habitat damage or potential damage. Further water quality information related to habitat in the basin can be found in Ihe Crilical Stream Inventorv of Soos Creek, published by Metro. Effects of Urbanization Low levels of development in most parts of the Soos Creek Basin, logether ..... ith a well-functioning natural drainage system, have kept serious erosion, sedimentation, and habitat damage to a minimum until nOW. However, the present and projected rales of development indicate that there could be increasing amounts of damage. as suggested by Ihe types of problems observed during reconnaissance. The expansion of impervious surfaces in the basin is already beginning to accelerate Ihe rates and volumes of sloIlDW3ter floy,.ing inlO (and reducing the capacities of) both nalural and artificial channels. Impervious surfaces are also reducing the amount of highly pervious soils available to absorb runoff. The predictable impacts are already in evidence: erosion, mass-wasting, sedimentation, and degraded waler quality and olher habitat destruction. The following section provides a more detailed account of problems found during field investigation. C. Speciftc Problems Identified The study team examined numerous sites along the main slem of Big Soos, Little SoDs, and West Soos Creeks, as well as 21 small drainages tributary to these main stems. Several of Ihe most significant problems found during reconnaissance are described below. 3 Soos Creek Basin (continued) 1. Bank failures. On Tributary 0072A, river mile .30, for example, there exists a major bank failure triggered by bank undercutting. The source of the problem appears to be increased runoff from street construction. Unless flows are intercepted and redirected to storm sewers or other facilities, there "ill be increased bank erosion and consequential deterioration of property and stream habitat. 2 Channel Erosion. This includes both instream and bank erosion caused by large volumes of runoff emerging from storm drains and washing away highly erodible soils. This creates a new, deeply incised channel that enlarges over time. One example of this problem occurs on Tributary 0072 near the SIR in the lower part of the basin. Large expanses of pavement at this location have contributed to high volume flows and channel erosion. Flooding and potential flooding. In numerous locations, development has increased the amount of runoff entering existing drainage facilities Or otherwise impeded the ability of natural systems to carry the amount of runoff. When drainage systems fail to function as they were intended, flooding can occur. Increased development without concurrent increases in drainage facilities adds to the possibility that serious flooding ,,;11 occur. On Tributary 0092, river mile 1.20, for example (collection paint 11), the Little Soos has been contained and manicured as it passes through a developed plat. SUCh alteration to a natural drainage channel reduces the stream's capacity in places. The result has been the regular semi-annual flooding of some homes. Further development could aggravate these kinds of flooding problems. 4. Poor stream habitat due to: a. Lack of overhead canopy and streamside vegetation.. Overhead canopy stabilizes water temperature, while streamside vegetation protects banks from erosion. b. Contamination by IM:stock fea:s. In areas of the basin where livestock have extensive access to streams, water quality has become degraded by animal feces. These cause harmful nutrients to be added to the water which can threaten fISh survival c.. Erosion. Streambank and channel erosion, already descnoed above, is caused in part by livestock access. On Tributary 0073, river miles 3.6Q-4.70, Cor example, there exists poor stream habitat because livestock have trampled and denuded banks of vegetation; this has led to the sedimentation of spawning areas and caused turbidity. IV. RECOMMENDATIONS FOR ACTION P:SCB The follo";ng recommendations are based on findings of the field team and reflect the original goals of the Basin Reconnaissance Program, as outlined in the introduction of this repan. A Inform appropriate governmental agencies of the detailed findings from the reconnaissance of this basin. Project representatives should meet ,,;th staff from King ( P:SCB Saos Creek Basin (continued) County Roads Division, Surface Water Management Division, Building and Land Development, and other interested agencies to transmit relevant information. B. Reevaluate sperific policy issues regarding swface water management. These may include the need to: 1. JmpIO\'C enforcement of wetlands regulations to maintain these areas in tbeir natural states. This will insure their continued function as surface water quality and quantity controllers, as well as preserve their habitat value. If regulation proves ineffective, the County should secure easements or consider other means to preserve wetland areas. 2 Require the establishment of undisturbed buffers and setbacks adjacent to natural drainage swales. Variations in stream morphology and geOlogy indicate the need for stream corridor guidelines that take these into consideration. Improve enforcement of "no clearing" covenants in these sensitive areas or seek County easements or actual ownership. Fencing along streams in livestock areas would help water quality and reduce erosion and sedimentation. 3. 4. 5. 6. Investigate and promote the inr.ltration of surface water where feasible and economical to reduce increased runoff from developed areas. Also, encourage the use of grass swales and open ditch conveyance systems to improve infiltration and water quality enhancement capacity. Areas of high filtration are identified on final display maps (for the Basin Reconnaissance Program) in the offices of Surface Water Management, Building and Land Development, and Basin Planning. Require tbe tigbtlining of storm-drainage outfalls down steep or sensitive slopes using state-of·the-an facilities, including high density polyethylene pipe with energy dissipation at the outfall. Reevaluate stormwater rate and ~e release regulations for new developments. Current regulations may be inadequate and result in unacceptable downstream erosion that causcs propeny damage and loss of habitat. Increase current maintenanCe levels for King County surface water RID and c:otM:yaDce facilities. Due to the lack of funding. maimenance of existing facilities is sometimes insuffICient and results in facility dysfunction and failure. These will only be aggravated by additional upstream development. 5 P:SCB Soos Creek Basin (continued) C. Prepare a comprehensive basin plan 10 consider, al a minimum, the need 10: 1. Enhance and utilize the extensive existing wetlands as regional stonu-<ieteotion facilities ",ithout jeopardizing habitat values. Prepare a schedule for the anticipated need for these hydrologic enhancements as they relate to projected development in the basin and impact the wetland ecology. 2 FPmin.e existing storm-<letention and conveyance facilities to determine whether their control orifices are properly sized to optimize the detention site and achieve the maximum benefit to the downstream systems. 3. Establish floodplains in Iow·lying areas of slight gradienl for existing and developed runoff conditions, i.e~ adjacent to wetlands, panicularly for wetlands proposed as regional detention sites where inundation of adjacent propenies may be significant. 4. Identify streanJ reaches critical to the maintenance of anadromous and trout populations. 5. Review geologic imding:; from this study in order to identify areaS of particular soils' sensitivity and develop special analysis criteria for new developments. D. Construct the capital impro...ement projects acoording to the ClP priority selection criteria. These projects, identified in Appendix B of this report, include projects to: 1 Cab"brate and retrofit existing detention-eontrol structures and to improve existing conveyance systems. 2 Stabilize channels and slopes. 3. PrcMde regional detention facilities, including the utilization of wetlands, where biological assessment has determined that the natural habitat values "'ill not be significantly altered. E. Maintain or enhance the instream and riparian habitats. 1. Maintain wetlands and buffer areas aJ'OUDd them. These provide both valuable ",ildlife habitat and natural stonnwater storage that helps to maintain year.round baseflO'.is in the stream. 2 Adopt a streanJ-oorridor policy in the Soos Creek Community Plan to protect the stream corridor from damaging types of land uses in adjacent areas. 3. EnC01lJ3ge the Washington State Depanment of FISheries to allow use of the natural streanJ system for salmon spawning. Maintain a natural run of all the indigenous anadromous species. 4. Prohibit idling in tbe 100-year floodplain. The County should establish regulations to prevent the loss of floodplains in order to maintain their natural U storage for floodwaters and guard against degradation of important fish and wildlife habitat. 6 " ,:;. ,,,," .. .,,!. ~l '"' SOOS CREEK BASIN ..... ......

APPENDIX B CAPITAL IMPROVEMENT PROJECT RANKING 5005 CREEK BASIN Prior to the Soos Creek watershed field reconnaissance, 13 projects had been identified and rated using the OP selection criteria developed by the Surface Water Management (SWM) Division and the Natural Resources and Parks Division. Following the reconnaissance, 20 projects remain proposed for this area. They include the 7 new, previously unidentified and unrated projects plus the initial 13 projects. The previous SWM capital improvements project list for the Soos Creek Basin had an estimated cOS! of S3,450,000, while the revised list decreases to an estimated cost of S2,622,000. This 24% reduction in estimated capital costs is due mainly to downward revised cost figures for acquiring or securing easements over wetlands. The follO\\ing t~ble summarizes the scores and costs for the OPs proposed for the Hylebos Creek Basin. The projects were rated according to previously established SWM Program Citizen Advisory Committee criteria. The projects ranked below are those for which the first rating question, ELEMENT 1: "GOINO-GO; could be answered affirmatively. The projects can now be considered for merging into the "live" CIP list. Any project scoring over 100 points should be considered for incorporation into the six-year CIP plans. RANK PROJECT NO.

In addition, the subject property drains to an on-site closed depression. Based on a review of the drainage complaints in the downstream drainage course, there are no existing constrictions or lack of capacity in the existing drainage system. Nor did the field reconnaissance find any potential restrictions of lack of capacity in the existing drainage system downstream from the site. 3.1 Conveyance System Nuisance Problems (Type 1) Conveyance system nuisance problems, in general, are defined as any eXlstmg or predicted flooding or erosion that does not constitute a severe flooding or erosion problem. Conveyance system nuisance problems are defined as flooding or erosion that results in the overflow of the constructed conveyance system for runoff events less than or equal to a lO-year event. Examples include inundation of a shoulder or lane of a roadway. Overflows collecting in yards or pastures, shallow flows across driveways, minor flooding in crawlspaces of unheated garages/outbuildings and minor erosion. Based on a review of the drainage complaints provided by King County, there is no evidence of past conveyance system nuisance problems occurring nor is there any evidence of any occurring during our site visit. However, property owners to the south of the project site have indicated that during peak storm events the on-site closed depression does backup through the site onto their property south of the site, almost to their access road to property further to the east and this is all prior to the on-site closed depression overtopping the S.E. Petrovitsky Road right-of-way over the sidewalk and into the conveyance system of S.E. Petrovitsky Road. 3.2 Severe Erosion Problems (Type 2) Severe erosion problems are defined as downstream channels, ravines, or slopes with evidence of or potential for erosion/incision, sufficient to pose a sedimentation hazard to downstream conveyance systems or propose a landslide hazard by undercutting adjacent slopes. Severe erosion problems do not include roadway or minor ditch erosion. Based on our site visit and the King County drainage complaints, there is no evidence of or potential for erosion/incision sufficient to pose a sedimentation hazard to the downstream conveyance systems evident anywhere along the downstream drainage course. 3.3 Severe Flooding Problems (Type 3) Severe flooding problems can be caused by conveyance system overflows or the elevated water surfaces of ponds, lakes, wetlands, or closed depressions. Severe flooding problems are defined as follows: Flooding of the finished area of a habitable building for runoff events less than or equal to the lOO-year event. Examples include flooding of finished floors of homes and commercial or industrial buildings. Flooding in electricallbeating systems and components in the crawlspace or garage of a home. Such problems are referred to as "severe building flooding problems." 1 101 l.OOl.doc [JPJ/dill] Flooding over all lanes of a roadway or severely impacting a sale access driveway for runoff events less than or equal to the 100-year event. Such problems are referred to as "severe roadway flooding problems." As mentioned previously, there is no evidence of flooding from the drainage complaints or from our site visit downstream of the subject property. However, the downstream drainage course is in a streambed and there is a 100-year Floodplain Map by the Federal Emergency Management Agency of Soos Creek with potential flooding during the 100-year storm event all along the streambed course downstream from the subject property. Most of the area surrounding the downstream drainage course is developed property with single-family residence and condominiums, etc., located all throughout the area. The downstream drainage course does flow through a large wetland area comprising over 100 acres, which is all forested and will remain that way after development of this project site. Almost the entire drainage course consists of following Soos Creek. The portion of the downstream drainage course investigated by the site visit and a review of the soils map indicates that the downstream drainage course occurs through Alderwood, Seattle muck, and Everett-type soils, all of which are till-type soils, except for the Everett, which is an outwash-type soil that is just a small portion of the downstream drainage course. The field reconnaissance for the off-site analysis drainage report was conducted on May 14, 2003. It was raining slightly at the time and the skies were overcast. The high temperature on this date was approximately 55 to 60 degrees. llOll.OOl.doc [JPJ/dm] TASK 4 DRAINAGE SYSTEM DESCRIPTION AND PROBLEM DESCRIPTIONS TASK 4 DRAINAGE SYSTEM DESCRIPTION AND PROBLEM DESCRIPTIONS Runoff leaves the site either by sheetflowing off the north property line of the site after overtopping the closed depression, or else sheetflowing off the east property line of the site immediately into the same downstream drainage course, although a little further downstream from the previously mentioned overflow. The vast majority of the runoff leaves the site at the north property line after overtopping the closed depression where it flows into the right-of-way of S.E. Petrovitsky Road and enters a pipe conveyance system for approximately 200 feet until discharging into a manhole where runoff is collected and conveyed underneath S.E. Petrovitsky Road and discharged on the south side of S.B. Petrovitsky Road, immediately into Soos Creek. Runoff then courses south for the most part, passing through an 18-inch RCP culvert under an access road and continuing easterly through thick vegetation, forestland, and wetland areas passing through another culvert under l22nd Place S.B. After that, the runoff enters the large Soos Creek Wetland No.2 where runoff courses southerly all the way to l82nd Street S.B., where it is conveyed underneath the prolongation of that street through twin 42-inch RCP culverts. For a review of all the drainage complaints provided by King County see Exhibit K -Drainage Complaints. There are no complaints concerning low conveyance capacity, flooding, or erosion in the downstream drainage course within a mile of the site. We have investigated the attached complaints that we believe to be near the downstream drainage course based on the complaint list. After review of each complaint there is none that were concerning runoff from the subject property or any other properties concerning low flow conveyance capacity, flooding, or erosion. 1101 I.OOI.doc [iPi/dml EXHIBIT K Drainage Complaints MAY. 8.2003 3:01PM KC WLRD NO.S1S P.V5 1/011 King County Water and Land Resources (WLR) Division 201 S Jackson St, Suite 600 Seattle, WA 98104-3855 FAX To: &tfemt1/A-'4 ~AM1?

The Soos Creek ohannel on the north side of 11S~ Ave SE between Units C and 0 on the attached site plan was fairly full with a water level about 3-4 feet below the road le~el. The debris level along the edge of the channel showed that a water level had been about 1-1.5 foot higher than the exieting level. Based on the slow rotation of the water surface ae the south end of the ch~el, the ohannel was slowly draining south thJ;"Ough the 2-24inch culverts under 118,h Ave SB. The tennis courts on the south Bide of the road were wet and looked as though several feet of water had been ponded there recently. The NW-SE channel located just Bouth of the Reoreation Build.ing Wae very full and appeared to be draining'S! at the outlet of the culverts under 119'". Via phone, I talked 'to Carter On 11-20-01. she said the channel north of 118~ had flooded to within about one foot of the top of ite banks and about ~ feet of water had ponded in the tennis courts on the south aide of 119"'. After conferring in our office with Larry Gettle and Mike Malnerich, I called Carter baok on 11-28-01 and told her the flooding in the channel and tennis courts were normal for a heavy 3 day rainfall with partial plugging of one Or more downstream oulvert entrances. I thanked her for her complaint and gave her our 206-296-1900 complaint number and the roads 24-hour complaint number at 206-296-S100.

' TASKS MITIGATION OF EXISTING AND POTENTIAL PROBLEMS TASK 5 MITIGATION OF EXISTING AND POTENTIAL PROBLEMS The area downstream of the proposed project known as Petro Vista Plat does not exhibit any potential problems, other than the on-site wetland that is a closed depression, nor is nor is there evidence of any existing problems in this downstream drainage course. Since the 1998 King County, Washington Surface Water Design Manual has indicated that basic water quality and Levell Flow Control are the required means of treating and detaining runoff, which meets the requirements of the Soos Creek basin plan as well. However, this project assumes those are inadequate as stated by King County in the previously mentioned letter. This letter requires a Water Quality Menu for the sphagnum bog treatment course to be followed and more restrictive flow control since the site could potentially have an impact on downstream properties. This project will hopefully neither aggravate nor create a problem as specified in the problem specific mitigation set forth in Section 1.2.2.1 of the 1998 King County, Washington Surface Water Design Manual as delineated in Task 4 of this report. A Level 2 or Level 3 off-site analysis should not be required for this project site as there is no evidence of existing or potential problems identified in this Levell analysis other than the on-site closed depression. In addition, the project site is not flat, nor is the downstream drainage course extremely flat. It is fairly constant in slope and the site does not contribute more than 15 percent of the total peak flow drainage downstream from the site. 11011.00l.doc [JPl/dmj )0 OFFICE OF THE HEARING EXAMINER KING COUNTY, WASHINGTON 400 Yesler Way, Room 404 Seattle, Washington 98104 Telephone (206) 296·4660 Facsimile (206) 296· 1654 April 30, 2004 CORRECTION TO REPORT AND DECISION SUBJECT: Department of Development and Environmental Services File No. L02P0012 Proposed Ordinance No. 2004·0143 Location: Applicant: PETRO VISTA Preliminary Plat Application Approximately on the southeast comer of the intersection of 118'" Avenue Southeast and Southeast Petrovitsky Road Leroy Surveyors & Engineers Inc., represented by Paul Green Leroy Surveyors & Engineers, Inc. 1103 Shaw Road PuyallUp, Washington 98372 Telephone: (253) 848·6608 King County: Department of Development and Environmental Services, represented by Fereshteh Dehkordi 900 Oakesdale A venue Southwest Renton, Washington 98055·1219 Telephone: (206) 296·7173 Facsimile: (206) 296·6613 This is a corrected report and decision that was mailed on April 29, 2004.

Except as modified herein, the facts set forth in the King County Land Use Services Division's preliminary report to the King County Hearing Examiner for the April 27, 2004 public hearing are found to be correct and are incorporated herein by reference. The LUSD stafTrecommends approval of the application, subject to conditions. The SEPA MDNS condition as described within the staff report should be corrected so that the word "derbies" reads "debris". L02P0012-Petro Vista 3 3. Dale VanDerschelden has filed a preliminary plat application to subdivide 3.83 acres into 23 lots for single-family residential development. Many of the small R-6 zoned lots will be constructed with attached residential structures. The property is within a rapidly urbanizing area located south ofPetrovitsky Road about I mile east of its intersection with the Benson Highway. 4. The major complications with respect to this plat application relate to wetland issues. The tract B onsite wetland functions as a closed depression and overflows Petrovitsky Road to its north during major storm events. As a consequence, most site drainage will be rerouted to a detention tract located directly to the wetland's east, with the wetland itself only receiving a reduced flow sufficient to maintain its hydrology. Since the wetland will no longer be allowed to overflow, existing problems relating to drainage backup on properties to the south should also be resolved. 5. An offsite wetland to the east and its outlet stream have been identified by DDES staff as part of the Soos Creek headwaters system and assigned a class I wetland rating and a class 2 S stream category respectively. Accordingly, the eastern flank of the Petro Vista plat will be constrained by sensitive areas buffers. Moreover, DDES has determined that the off site stream is in hydraulic continuity with a downstream bog, and the plat will be required to provide enhanced water quality treatment of site runoff. 6. Students from Petro Vista will talk to Renton School District schools, including Benson Elementary located at 116"' Avenue Southeast and Southeast IS6'h Street. There are no shoulders or sidewalks along IIS'h Avenue Southeast south of the plat, but the roadway only carries a moderate amount of traffic. An alternative route further west via Petrovitsky Road and 116"' Avenue Southeast provides better walking facilities but is characterized by more traffic. In view ofthe small size of the plat in the context of an area-wide lack of walking facilities, it is not appropriate to require the Applicant to cure this neighborhood deficiency. CONCLUSIONS: 1. If approved subject to the conditions imposed below, the proposed subdivision makes appropriate provision for the public health, safety and welfare; serves the public use and interest; and meets the requirements ofRCW 58.17.110. 2. The conditions of approval imposed herein, including dedications and easements, will provide improvements that promote legitimate public purposes, are necessary to serve the subdivision and are proportional to its impacts; are required to make the proposed plat reasonably compatible with the environment; and will carry out applicable state laws and regulations and the laws, policies and objectives of King County. DECISION: The preliminary plat application for Petro Vista, as revised and received on February 26, 2004, is APPROVED, subject to the following conditions of final plat approval: 1. Compliance with all platting provisions of Title 19 of the King County Code. 2. All persons having an ownership interest in the subject property shall sign on the face of the final plat a dedication that includes the language set forth in King County Council Motion No. 5952. L02POO l2-Petro Vista 4 3. The plat shall comply with the base density (and minimum density) requirements of the R-6-S0 zone classification. All lots shall meet the minimum dimensional requirements of the R-6 zone classification or shall be as shown on the face of the approved preliminary plat, whichever is larger. except that minor revisions to the plat which do not result in substantial changes may be approved at the discretion of the Department of Development and Environmental Services. 4. All construction and upgrading of public and private roads shall be done in accordance with the King County Road Standards established and adopted by Ordinance No. 11187, as amended (1993 KCRS). 5. The Applicant must obtain the approval of the King County Fire Protection Engineer certifying the adequacy of the fire hydrant, water main, and fire flow to meet the standards of Chapter 17.08 . ofthe King County Code. 6. Final plat approval shall require full compliance with the drainage provisions set forth in King County Code 9.04. Compliance may result in reducing the number and/or location oflots as shown on the preliminary approved plat. Preliminary review has identified the following conditions of approval which represent portions of the drainage requirements. All other applicable requirements in KCC 9.04 and the Surface Water Design Manual (SWDM) must also be satisfied during engineering and final review. a. Drainage plans and analysis shall comply with the 1998 King County Surface Water Design Manual and applicable updates adopted by King County. DDES approval of the drainage and roadway plans is required prior to any construction. b. Current standard plan notes and ESC notes, as established by DDES Engineering Review, shall be shown on the engineering plans. c. The following note shall be shown on the final recorded plat: All building downspouts, footing drains, and drains from all impervious surfaces such as patios and driveways shall be connected to the permanent storm drain outlet as shown on the approved construction drawings # on file with DDES and/or the King County Department of Transportation. This plan shall be submitted with the application of any building permit. All connections of the drains must be constructed and approved prior to the final building inspection approval. For those lots that are designated for individual lot infiltration systems, the systems shall be constructed at the time of the building permit and shall comply with plans on file." d. Storm water facilities shall be designed using the KCRTS Level One Flow Control standard. Water quality facilities shall also be provided using the Sphagnum bog protection menu. As shown on the conceptual drainage plan, the outlet of the detention pond and water quality facility will connect to the existing conveyance system along Petrovitsky Road and small areas of undetained flows will be used to maintain wetland hydrology within Tract B. Based upon the final drainage analysis, the size of the proposed drainage tracts may have to increase to accommodate the required detention storage volumes and water quality facilities. All runoff control facilities shall be located in a separate tract and dedicated to King County, unless portions of the drainage tract are used for recreation space in accordance with KCC 2IA.l4.1S0. L02P00I2~Petro Vista 5 e. The final drainage analysis shall evaluate the requirements for ofT-site bypass as outlined in the drainage manual on page 1-36. As noted in the design criteria, the contribution of flows to an onsite wetland must be maintained and the natural attenuation of flows under pre-developed conditions must also remain. The design engineer shall evaluate all areas which may contribute ofTsite flows including the ditch along IISth Avenue SE. As noted in the applicants Level One OfTsite analysis dated May 15, 2003, during major storm events the onsite wetland fills up and overtops to Petrovitsky Road and also backs up water across the south property line. The design engineer shall evaluate any potential flooding issues and provide drainage designs which adequately prevent potential drainage problems. As shown on the preliminary plat, an interceptor swale is proposed along the south property line oflots 10 and II. f. The final drainage plans and technical reports shall evaluate all applicable design criteria for onsite closed depressions and ponding areas as discussed in the drainage manual on page 3-54. The existing wetland in Tract B currently captures surface water from ofT site areas and the western portion ofthe project area which may influence the storm water modeling for pre-and post-developed flow rates and volumes. During final engineering review, King County will review and determine how much ofT site flow and/or undetained project areas may drain to the wetland in Tract B without pretreatment in detention or water quality facilities. g. The final engineering plans and recorded plat shall show the 100-year floodplain boundaries as required by Special Requirements No.2 in the drainage manual. 8. The proposed subdivision shall comply with the 1993 King County Road Standards (KCRS) including the following requirements: a. Southeast 176th Court shall be improved as an urban subaccess street. b. One hundred eighteen (118"') Avenue Southeast shall be improved as an urban neighborhood collector along the frontage of the subject property. As noted in KCRS 2.03, for neighborhood collector streets intersecting with an arterial (SE Petrovitsky), the width must be 36-feet wide for the first 150 feet. A 25-foot right-of-way line radius is also required as shown in KCRS 2.10. c. One hundred eighteen (1ISth) Avenue SE is designated a neighborhood collector street which may require designs for bus zones and tum outs. As specified in KCRS 2.16, the applicant or his engineering consultant shall contact Metro and the local school district to determine specific requirements. d. Street illumination shall be provided at intersections with arterials in accordance with KCRS 5.05. f. Modifications to the above road conditions may be considered by King County pursuant to the variance procedures in KCRS 1.08. 9. During preliminary site inspections, King County has identified fill material, building debris, and a concrete foundation within the site. To address the required site grading and designs for development, the applicant shall submit a geotechnical report with the engineering plans to address all applicable earthwork, site preparation, road construction, and utility installation. The L02POO 12-Petro Vista 6 geotechnical engineer shall also evaluate the soil conditions and requirements for the proposed storm water vault located within Tract A. Structural plans and calculations for the vault must be prepared by a licensed structural engineer. 10. All utilities within proposed rights-of-way must be included within a franchise approved by the King County Council prior to final plat recording. 1 I. King County Code 16.82.150D requires seasonal limitations for construction within the Soos Creek basin. During the period October I through March 31, clearing and grading is not allowed unless certain provisions are complied with as outlined in the code. The applicants engineering plans shall demonstrate compliance with the applicable code requirements and provide notes referencing the seasonal limitations set forth in KCC 16.82.1S0D. 12. The applicant or subsequent owner shall comply with King County Code 14.7S, Mitigation Payment System (MPS), by paying the required MPS fee and administration fee as determined by the applicable fee ordinance. The applicant has the option to either: (1) pay the MPS fee at final plat recording, or (2) pay the MPS fee at the time of building permit issuance. If the first option is chosen, the fee paid shall be the fee in effect at the time of plat application and a note shall be placed on the face of the plat that reads, "All fees required by King County Code 14.75, Mitigation Payment System (MPS), have been paid." If the second option is chosen, the fee paid shall be the amount in effect as ofthe date of building permit application. 13. Lots within this subdivision are subject to King County Code 2IA.43, which imposes impact fees to fund school system improvements needed to serve new development. As a condition of final approval, fifty percent (SO%) of the impact fees due for the plat shall be assessed and collected immediately prior to recording, using the fee schedules in effect when the plat receives final approval. The balance of the assessed fee shall be allocated evenly to the dwelling units in the plat and shall be collected prior to building permit issuance. 14. There shall be no direct vehicular access to or from lISIh Avenue SE from those lots which abut it, except lot 23. A note to this effect shall appear on the engineering plans and final plat. IS. The proposed subdivision shall comply with the Sensitive Areas Code as outlined in KCC 2lA.24. Permanent survey marking, and signs as specified in KCC 21 A.24.160 shall also be addressed prior to final plat approval. Temporary marking of sensitive areas and their buffers (e.g., with bright orange construction fencing) shall be placed on the site and shall remain in place until all construction activities are completed.

Except as modified herein, the facts set forth in the King County Land Use Services Division's preliminary report to the King County Hearing Examiner for the April 27, 2004 public hearing are found to be correct and are incorporated herein by reference. The LUSD staff recommends approval of the application, subject to conditions. The SEPA MDNS condition as described within the staff report should be corrected so that the word "derbies" reads "debris". L02P0012-Petro Vista 3 3. Dale VanDerschelden has filed a preliminary plat application to subdivide 3.83 acres into 23 lots for single-family residential development. Many of the small R-6 zoned lots will be constructed with attached residential structures. The property is within a rapidly urbanizing area located south ofPetrovitsky Road about I mile east of its intersection with the Benson Highway. 4. The major complications with respect to this plat application relate to wetland issues. The tract B onsite wetland functions as a closed depression and overflows Petrovitsky Road to its north during major storm events. As a consequence, most site drainage will be rerouted to a detention tract located directly to the wetland's east, with the wetland itself only receiving a reduced flow sufficient to maintain its hydrology. Since the wetland will no longer be allowed to overflow, existing problems relating to drainage backup on properties to the south should also be resolved. 5. An offsite wetland to the east and its outlet stream have been identified by DDES staff as part of the Soos Creek headwaters system and assigned a class I wetland rating and a class 2 S stream category respectively. Accordingly, the eastern flank ofthe Petro Vista plat will be constrained by sensitive areas buffers. Moreover, DDES has determined that the offsite stream is in hydraulic continuity with a downstream bog, and the plat will be required to provide enhanced water quality treatment of site runoff. 6. Students from Petro Vista will talk to Renton School District schools, including Benson Elementary located at 116 1h Avenue Southeast and Southeast IS6'o Street. There are no shoulders or sidewalks along IISIh Avenue Southeast south of the plat, but the roadway only carries a moderate amount of traffic. An alternative route further west via Petrovitsky Road and 116'0 Avenue Southeast provides better walking facilities but is characterized by more traffic. In view of the small size of the plat in the context of an area-wide lack of walking facilities, it is not appropriate to require the Applicant to cure this neighborhood deficiency. CONCLUSIONS: I. If approved subject to the conditions imposed below, the proposed subdivision makes appropriate provision for the public health, safety and welfare; serves the public use and interest; and meets the requirements ofRCW 58.17.110. 2. The conditions of approval imposed herein, including dedications and easements, will provide improvements that promote legitimate public purposes, are necessary to serve the subdivision and are proportional to its impacts; are required to make the proposed plat reasonably compatible with the environment; and will carry out applicable state laws and regnlations and the laws, policies and objectives of King County. DECISION: The preliminary plat application for Petro Vista, as revised and received on February 26, 2004, is APPROVED, subject to the following conditions of final plat approval: I. Compliance with all platting provisions of Title 19 of the King County Code. 2. All persons having an ownership interest in the subject property shall sign on the face of the final plat a dedication that includes the language set forth in King County Council Motion No. 5952. L02POO 12-Petro Vista 4 3. The plat shall comply with the base density (and minimum density) requirements of the R-6-S0 zone classification. All lots shall meet the minimum dimensional requirements of the R-6 zone classification or shall be as shown on the face of the approved preliminary plat, whichever is larger, except that minor revisions to the plat which do not result in substantial changes may be approved at the discretion of the Department of Development and Environmental Services. 4. All construction and upgrading of public and private roads shall be done in accordance with the !(jng County Road Standards established and adopted by Ordinance No. 11187, as amended (1993 KCRS). 5. The Applicant must obtain the approval ofthe King County Fire Protection Engineer certifYing the adequacy of the fire hydrant, water main, and fire flow to meet the standards of Chapter 17.08 of the !(jng County Code. 6. Final plat approval shall require full compliance with the drainage provisions set forth in !(jng County Code 9.04. Compliance may result in reducing the number and/or location oflots as shown on the preliminary approved plat. Preliminary review has identified the following conditions of approval which represent portions of the drainage requirements. All other applicable requirements in KCC 9.04 and the Surface Water Design Manual (SWDM) must also be satisfied during engineering and final review. a. Drainage plans and analysis shall comply with the 1998 King County Surface Water Design Manual and applicable updates adopted by King County. DDES approval of the drainage and roadway plans is required prior to any construction. b. Current standard plan notes and ESC notes, as established by DDES Engineering Review, shall be shown on the engineering plans. c. The following note shall be shown on the final recorded plat: All building downspouts, footing drains, and drains from all impervious surfaces such as patios and driveways shall be connected to the permanent storm drain outlet as shown on the approved construction drawings # on file with DDES and/or the King County Department of Transportation. This plan shall be submitted with the application of any building permit. All connections of the drains must be constructed and approved prior to the final building inspection approval. For those lots that are designated for individual lot infiltration systems, the systems shall be constructed at the time ofthe building permit and shall comply with plans on file." d. Storm water facilities shall be designed using the KCRTS Level One Flow Control standard. Water quality facilities shall also be provided using the Sphagnum bog protection menu. As shown on the conceptual drainage plan, the outlet ofthe detention pond and water quality facility will connect to the existing conveyance system along Petrovitsky Road and small areas of undetained flows will be used to maintain wetland hydrology within Tract B. Based upon the final drainage analysis, the size of the proposed drainage tracts may have to increase to accommodate the required detention storage volumes and water quality facilities. All runoff control facilities shall be located in a separate tract and dedicated to King County, unless portions of the drainage tract are used for recreation space in accordance with KCC 21 A.14.180. ," L02POOI2-Petro Vista 5 e. The final drainage analysis shall evaluate the requirements for off-site bypass as outlined in the drainage manual on page 1-36. As noted in the design criteria, the contribution of flows to an onsite wetland must be maintained and the natural attenuation of flows under pre-developed conditions must also remain. The design engineer shall evaluate all areas which may contribute offsite flows including the ditch along 118"' Avenue SE. As noted in the applicants Level One Offsite analysis dated May 15,2003, during major storm events the onsite wetland fills up and overtops to Petrovitsky Road and also backs up water across the south property line. The design engineer shall evaluate any potential flooding issues and provide drainage designs which adequately prevent potential drainage problems. As shown on the preliminary plat, an interceptor swale is proposed along the south property line oflots 10 and 11. f. The final drainage plans and technical reports shall evaluate all applicable design criteria for onsite closed depressions and ponding areas as discussed in the drainage manual on page 3-54. The existing wetland in Tract B currently captures surface water from off site areas and the western portion of the project area which may influence the storm water modeling for pre-and post-developed flow rates and volumes. During final engineering review, King County will review and determine how much off site flow and/or undetained project areas may drain to the wetland in Tract B without pretreatment in detention or water quality facilities. g. The final engineering plans and recorded plat shall show the 100-year floodplain boundaries as required by Special Requirements No.2 in the drainage manual. 8. The proposed subdivision shall comply with the 1993 King County Road Standards (KCRS) including the following requirements: a. Southeast 176"' Court shall be improved as an urban subaccess street. b. One hundred eighteen (118"') Avenue Southeast shall be improved as an urban neighhorhood collector along the frontage of the subject property. As noted in KCRS 2.03, for neighborhood collector streets intersecting with an arterial (SE Petrovitsky), the width must be 36-feet wide for the first ISO feet. A 25-foot right-of-way line radius is also required as shown in KCRS 2.1 O. c. One hundred eighteen (118"' ) A venue SE is designated a neighborhood collector street which may require designs for bus zones and tum outs. As specified in KCRS 2.16, the applicant or his engineering consultant shall contact Metro and the local school district to determine specific requirements. d. Street illumination shall be provided at intersections with arterials in accordance with KCRS 5.05. f. Modifications to the above road conditions may be considered by King County pursuant to the variance procedures in KCRS 1.08. 9. During preliminary site inspections, King County has identified fill material, building debris, and a concrete foundation within the site. To address the required site grading and designs for development, the applicant shall submit a geotechnical report with the engineering plans to address all applicable earthwork, site preparation, road construction, and utility installation. The L02POOI2-Petro Vista 6 geotechnical engineer shall also evaluate the soil conditions and requirements for the proposed storm water vault located within Tract A. Structural plans and calculations for the vault must be prepared by a licensed structural engineer. 10. All utilities within proposed rights-of-way must be included within a franchise approved by the King County Council prior to final plat recording. II. King County Code 16.82.150D requires seasonal limitations for construction within the Soos Creek basin. During the period October I through March 31, clearing and grading is not allowed unless certain provisions are complied with as outlined in the code. The applicants engineering plans shall demonstrate compliance with the applicable code requirements and provide notes referencing the seasonal limitations set forth in KCC 16.82.150D. 12. The applicant or subsequent owner shall comply with King County Code 14.75, Mitigation Payment System (MPS), by paying the required MPS fee and administration fee as determined by the applicable fee ordinance. The applicant has the option to either: (I) pay the MPS fee at final plat recording, or (2) pay the MPS fee at the time of building permit issuance. If the first option is chosen, the fee paid shall be the fee in effect at the time of plat application and a note shall be placed on the face of the plat that reads, "All fees required by King County Code 14.75, Mitigation Payment System (MPS), have been paid." If the second option is chosen, the fee paid shall be the amount in effect as of the date of building permit application. 13. Lots within this subdivision are subject to King County Code 2IA.43, which imposes impact fees to fund school system improvements needed to serve new development. As a condition of final approval, fifty percent (50%) of the impact fees due for the plat shall be assessed and collected immediately prior to recording, using the fee schedules in effect when the plat receives final approval. The balance of the assessed fee shall be allocated evenly to the dwelling units in the plat and shall be collected prior to building permit issuance. 14. There shall be no direct vehicular access to or from 118"' Avenue SE from those lots which abut it, except lot 23. A note to this effect shall appear on the engineering plans and final plat. IS. The proposed subdivision shall comply with the Sensitive Areas Code as outlined in KCC 2IA.24. Permanent survey marking, and signs as specified in KCC 2IA.24.160 shall also be addressed prior to final plat approval. Temporary marking of sensitive areas and their buffers (e.g., with bright orange construction fencing) shall be placed on the site and shall remain in place until all construction activities are completed. Preliminary plat review has identified the following specific requirements which apply to this project. All other applicable requirements from KCC 21A.24 shall also be addressed by the applicant. a. The Class I wetland near the east property line shall have a minimum buffer of 100 feet, measured from the wetland edge. b. The Class 2 wetland near the north boundary of the site shall have a minimum buffer of 50 feet, measured from the wetland edge. L02POO 12-Petro Vista 7 c. The Class 2S stream shalI have a minimum I OO-foot buffer, measured from the ordinary high water mark (OHWM). d. The stream, wetlands and their respective buffers shall be placed in a Sensitive Area Tract (SAT). e. A minimum building setback line of 15 feet shall be required from the edge of the tract. f. Buffer width averaging may be allowed by King County if it wiII provide additional protection to the wetland/stream or enhance there functions, as long as the total area contained in the buffer on the development proposal site does not decrease. In no area shall the buffer be less than 65 percent of the required minimum distance. To ensure such functions are enhanced a mitigation plan will be required for the remaining on-site sensitive areas. An enhancement plan shall be submitted for review during engineering review. g. A mitigation plan and financial guarantee/bond will be required for any proposed impacts of sensitive areas including buffers. The bond amount will include all components of the mitigation plan including, but not limited to, plantings, grading, fencing, signs, inspections, and monitoring for five years. h. Prior to commencing construction activities on the site, the applicant shall temporarily mark sensitive areas Tract(s) in a highly visible manner, and these areas must remain so marked until all development proposal activities in the vicinity ofthe sensitive areas are completed. i. Prior to approval of construction activities on the site, the boundary between the sensitive area Tract(s) and adjacent land shall be identified using permanent signs. Sign specifications shall be shown on the engineering plans and shall be installed every 50 feet or as deemed appropriate by county staff at the time of engineering review. J. During engineering plat review the applicant shall provide a wetland hydrology analysis to demonstrate how the wetland hydrology will be maintained post-construction. k. Detention out-fall structures maybe permitted within the wetland/stream buffers, however, structures shall be located in the outer edge of the buffer, if possible. All buffer impacts shall be mitigated. l. Development authorized by this approval may require other state and/or federal permits or approvals. It is the applicant's responsibility to correspond with these agencies prior to beginning work on the site. m. The following have been established under SEPA authority as necessary requirements to mitigate the adverse environmental impacts of this development. The Applicant shall demonstrate compliance with these items prior to final approval. 1) A four-foot tall fence shall be constructed along the edge of the Sensitive Area Tracts Band C. The fence shall follow the common boundaries of the wetland tracts and the adjoining lots and road. Fencing details, construction and location shall be shown on L02P00I2-Petro Vista the engineering plans for DDES review and approval. This mitigation is intended to reduce disturbance within the protective buffer and associated wetland. 8 2) All existing structures and other debris shall be removed from the sensitive area tracts and the area shall be restored in accordance with KCC 21A.24. n. The following note shall be shown on the final engineering plan and recorded plat: RESTRICTIONS FOR SENSITIVE AREA TRACTS AND SENSITIVE AREAS AND BUFFERS Dedication of a sensitive area tract/sensitive area and buffer conveys to the public a beneficial interest in the land within the tract/sensitive area and buffer. This interest includes the preservation of native vegetation for all purposes that benefit the public health, safety and welfare, including control of surface water and erosion, maintenance of slope stability, and protection of plant and animal habitat. The sensitive area tract/sensitive area and buffer imposes upon all present and future owners and occupiers of the land subject to the tract/sensitive area and buffer the obligation, enforceable on behalf of the public by King County, to leave undisturbed all trees and other vegetation within the tract/sensitive area and buffer. The vegetation within the tract/sensitive area and buffer may not be cut, pruned, covered by fill, removed or damaged without approval in writing from the King County Department of Development and Environmental Services or its successor agency, unless otherwise provided by law.

Petrovitsky Road and 118t11 Avenue S.E. in Section 33, Township 23 N, Range 5 E, W.M. The site address is 11925 S.E. Petrovitsky Road. Project Description The property owners are proposing to develop and subdivide a 3.83-acre site into 23 single-family residential lots. Site Description The property consists of King County Parcels 6196600380 and 6196600381. It is bordered to the north by S.E. Petrovitsky Road (S.E. 176t11 St.), to the west by 118t11 Ave. S.E., and to the east by a BPA power line right-of- way. There is an office building, a garage, a shed and an equipment yard located on the eastern half of the property. The land slopes down towards the center from the buildings, and the western and southern sides to create a small depression located in the north half of the property. This depression contains a small (approximately 0.12 acre) Class 2 Wetland. The onsite wetland is dominated by Scrub-Shrub vegetation [predominantly red-osier dogwood (Comus sericea)) with a developing forested class [predominantly Oregon ash (Fraxinus latifolia) and black cottonwoods (Populus balsamifera)). The upland has areas of Himalayan blackberries (Rubus procerus), mixed young forest dominated by Douglas firs (Pseudotsuga menziesil) and black cottonwoods, and open grassy areas. On the east side of the buildings, the land slopes down to the eastern border. This hillside is dominated by black cottonwoods with an understory dominated by trailing blackberries (Rubus ursinus) and snowberries (Symphoricarpos albus). Exhibit "A" shows the site vicinity map. Exhibit "B" shows the site plan with topographic contours. Drainage Delineation The project is located in the upper portion of the Upper Soos Creek drainage subbasin. For the purpose of this downstream analysis, an 1113-acre drainage area (291 times as large as the development site) is delineated by setting the downstream point at approximately 0.5 miles from the development site. (Exhibit "CO -Drainage Delineation Map). Petro Vista Level 1 Downstream Analysis 3 Drainage System Description The stormwater runoff from the site will be collected in a closed pipe network and stored in a detention pond before releasing into an on-site wetland at flow rates less than or equal to the pre-developed rates. The on site wetland is 5 ft deep with a storage volume of 64,890 cubic feet. The tributary area to this wetland is relatively small, largely confined within the property area. The wetland does not appear to have been overflowed in recent history as evidenced by lack of obvious outlet and high water mark. However, when overflow occurs, the water would run over the sidewalk into the closed pipe system along Petrovitsky Road. The stormwater entering this closed pipe system would travel approximately 275 feet to the east and end with a 36" culvert that discharges into an off-site wetland. The offsite wetland is primarily a reed canarygrass meadow (Phalaris arundinacea), with isolated Scrub-Shrub clusters [predominantly spirea (Spirea douglash) and Pacific willow (Salix lucida)] and a Scrub-Shrub fringe [predominantly Himalayan blackberry and western crabapple (Malus fusca)]. The majority of the wetland is located in the BPA transmission line R-O-W. The stormwater meanders in a southeasterly direction through the off-site wetland and the BPA R-O-W for approximately 275 feet and exits the offsite wetland through an 18" diameter culvert at the south edge. At this point, it begins to change direction and travels easterly for a~roximately 700 feet to a 36 inch diameter corrugated metal culvert under 122 Avenue. This is where it meets the headwaters of the Big Soos Creek and continues in a southerly direction. Resource Review The following information resources have been reviewed in preparation of the analysis. Soos Creek Basin Plan This report is a lengthy and comprehensive document that describes the existing conditions in Soos Creek Basin and predicts the potential impacts of future land uses on watershed ecosystem. The report provides recommended plans and alternative solutions to deal with the problems associated with urban development. The problems identified in the upper Soos Creek basin include increased peak flows, flooding and undersized channels and culverts. However, these problems do not appear to occur in the close vicinity of the site or in direct downstream area. Part of the report that is relevant to the upper Soos Creek area is attached as Exhibit "0". Petro Vista Level 1 Downstream Analysis 4 Reconnaissance Report No.2, Soos Creek Basin This report was written in 1986 when rapid urban development in this area just began. The report identified some surface water problems in Soos Creek Basin and proposed some drainage improvement projects to mitigate those problems. No specific problem or mitigation project was identified in the close vicinity of the site. The report is attached as Exhibit "E". FEMA Floodplain Map The proposed development site is not within a floodway or a floodplain, while the offsite wetland to the east and a large downstream area along the Big Soos Creek is classified as Zone AE, as indicated by the floodplain map (attached as Exhibit "Pl. Sensitive Areas Folio and Wetland Inventory The following categories of sensitive areas have been reviewed: Coal Mine Hazards, Erosion Hazards, Landslide Hazards, Seismic Hazards, National Wetland Inventory Wetlands, and King County Wetland Survey. None of above- mentioned sensitive areas exist within the development site. A seismic hazards area and a 134-acre King County wetland exist approximately 0.1 mile east of the property. A small NWI wetland exists approximately 0.2 mile downstream to the southeast. An erosion hazards area exists approximately 0.4 mile to the southeast. The sensitive areas folio map is attached as Exhibit "G". Soil Survey Map The soils on the property are mapped as Alderwood gravelly sandy loam, 6-15% slopes by the Soil Conservation Service (U.S. Department of Agriculture, 1973, see Exhibit "H"). The soil types have been confirmed by site visits. Drainage Problem The King County Water and Land Resources Division provided a list of complaints related to drainage problem in the general area of the proposed development site. We have checked the locations of the problems and did not find any problem that had originated from or directly connected to the site. The closest location where flooding problem once occurred was at 118 TH Ave SE cross Petrovitsky Road to the north in November 2001. The problem appeared Petro Vista Level 1 Downstream Analysis 5 - to be caused by partial clogging of one or more downstream culvert entrances and were considered normal for a heavy and extended rainfall. This problem was unrelated to the proposed development site by any means. The complete list of complaints and the original record of above-mentioned complaint are attached as Exhibit "I". Field Inspection of the Site We visited the site on two occasions, February 15, 2000 and February 22, 2000. It was cloudy but dry the first visit to the site. It was raining moderately on the second visit. On both occasions, there was no standing water observed in the on-site wetland. The actual drainage system appeared to match the description in the plan. No obvious nuisance problem could be identified at the site and close downstream area. Conclusions The on-site wetland provides a sufficiently large storage, evaporation and infiltration area for its relatively small tributary basin, which keeps the onsite surface runoff from releasing into downstream. Under normal circumstances, the on-site drainage system is effectively isolated from the offsite drainage system in terms of hydrauliC connection by surface water. The construction of the detention pond and release control structure will limit the runoff rates to the on- site wetland to the predeveloped level. So, even overflow from the wetland to downstream occurs in a big storm event, the flow rate will be unlikely to exceed the predeveloped flow rate. Based on this analysis and review of available information and our field inspection, we anticipate that the site development will not alter the existing drainage and will have no negative impact on downstream hydrology.

This format was chosen to facilitate review and ensure that the ultimate users of the plan will have direct access to discussions of"Jmpacts and mitigating measures. . Figure 1 shows the organization of this document. The document begins with a ~ short summary of the basin plan and FEIS. Next, the Current and Future -, Conditions section summarizes the detailed analyses of surface water issues in the system. This section corresponds to an "Existing Conditions' or -Affected Environment" discu.ssion of a stand'-alone FEIS. The Recommended Plan section then identifies the preferred course of watershed .~ management, including a preferred approach for each identified problem. A. discussion of preferred alternatives for area-specific conditions in six regions; of the Soos Creek system Is followed by preferred alternatives on a basinwide level. The cost and priority of the preferred alternatives are presented with preferred implementation met~ods. This section also includes the opinions of the Soos Creek Basin Plan Citizen Advisory Committee. The Alternative Solutions and Impacts section identifies and compares alternative solutions for area-specific problems in six regions of the Soos Creek system, as well as basinwide problems. This section identifies preferred alternatives. Finally, the generalized environmental Impacts of and mitigation for these alternatives, including the No-Attlon and Preferred Alternatives, are discussed in this section. The Background Information and References section documents the relevant elements of the environment for FEIS analysis, the SEPA distribution list for this. document, detailed tables of modeled flows, recommended implementation schedule, costs for land use, regulatory, and programmatiC recommendations, recommendations ranking criteria, and a list of references. Finally, public comments on the DEIS are shown with responses. -u;;; _ t==========================~====:================:============================= SUMMARY OF RECOMMENDED PLAN AND ITS IMPACTS INTRODUCTI ON (. =============================================================================== l. l I .. ( r ( ( SUMMARY OF RECOMMENDED PLAN AND ITS IMPACTS I NTRODUCTI ON . . The Soos Creek Basin Plan was developed under the King County SWM Program. The plan covers the Soos, Jenkins, and Covington Creek Basins in south nng County (FigurL2). Using field observations, the results of past studies, and computer modeling, the. Soos Creek Basin Plan evaluates today's stream flows, erOsion, . sediment deposition, stream habitat, and water quality. The plan then predicts how these conditions will change as the predominantly rural So os Creek area develops to suburban and urban densities. Finally, the plan recommends ways to reduce future resource damage and repair current surface water-related problems. The Soos Creek system exemplifies the difficulty of protecting a natural resource while simultaneously accommodating rapid population growth. Parts of the basin are currently rural and their streams are in good or excellent condition. Yet elsewhere, the basin is experiencing some of the fastest development in King County and displays many of the unintended problems associated with that activity. These problems include flooding, erosion, sedimentation, destruction of fish habitat, and degraded water quality. The results of this basin plan suggest that such consequences are a virtually inescapable byproduct of urban .growth. Mitigation imposed on new development, or correction of preexisting conditions, can lessen their impact. Yet stable stream channels, a healthy fishery, and clean water depend on the whole integrated function of a watershed. From the ground that first receives the rainfall to the channels that convey it downstream, no element is extraneous. Mitigation can replace a portion of functions lost when development takes place. But there are no data to suggest that all such functions can be replaced on the scale of a large watershed or even in a small subcatchment. The regional decisions on growth are therefore decisions on the future of our stream systems and quality of their waters as well: where is degradation tolerable, how much cost are we willing to accept for at most partial protection, and where are the resources so valuable and unspoiled that their protection should be paramount? This basin plan seeks to provide some of those answers, using a full spectrum of analytic tools and professional expertise. CONDITIONS IN THE SODS CREEK SYSTEM OVERVIEW Much of the SODS Creek system-currently is rural and its streams are in . relatively good condition, partitularly in the Jenkins and Covington Creek Basins. However, the SODS Creek area is one of the fastest growing areas in King County. The surface water effects of rapid development have only recently become evident. The Soos Creek system's extensive and relatively undisturbed network of streams, wetlands, lakes, forest cover, and large areas of highly infiltrative outwash deposits have up to now masked these effects in most areas. - 1 - . :' , ;. . , -'.~) -I ) ) ; -i' .~ -j ,( ( ( , • ~==============================~====================~========================== SUMMARY OF RECOMMEND EO PLAN AND ITS IMPACTS CONDITIONS IN THE 5005 CREEK SYSTEM Surface water management in the Soos Cree~ system presents a dual challenge: to reduce the surface water problems associated with suburban growth in the Soos Cree~ Basin to the west, and to preserve the elements of the natural hydrology and h.abltat in the more easter'.ly basins of Jen~ins and Covington Creeks that are critical to the high Quality, biological diversity, an~ productivity of this stream system. Recommendations reflect the differences in development-related impact between these two parts of the system. In the west, the recommendations see~ to correct and avoid the most damaging of those impacts. ' In th,e east, the goal of resource preservation is far more challenging, because the full spectrum of development Impacts iLSO difficult to contnrl. Yet the resource at rls~ here I s of crlt I ca I va I ue not only In Ki ng County but also in the Puget Sound Region as a whole. CONDITIONS Present stream flows cause periodic flooding of three County roads, a" par~ing lot, four houses, and two apartment buildings. In the' future, this flooding will Increase in both frequency and severity.' floodplains jn most parts of the system will widen due to increases In pea~ stream flows, predicted to be more than two times larger in some areas. One major erosion site is.a potent1il1 future threat to a' house 'and another !"s undermi nl n9 a County road. Erosion in two sma 11" steep tributari es contributes to downstream sedimentation, particularly at the Green River Hatchery. As pea~ flows increase in the future, the amount of sediment eroded a'nd transported in the malnstem of Soos Cree~ is -expected to roughly double. Only localized water Quality deg'radat{on has been observed in the SODS Creek system, Including high fecal coliform levels in Little SODS Creel: and high nutrient levels in lakes. Nutrients, sediment, and other pollutants carried by stonnwater runoff could pollute domestic water supply wells in areas with coarse gravelly soils. In the future, nonpolnt pollution of this type Is predicted to become an increasing threat to the use of the streams for water supply, fish habitat, and recreation.

'Because no single approach effectively addresses the broad range of surface water issues in the basin, a combination of basin management approaches Is recommended, Including: o Land Use Control s: Establishment of maximum densities of one unitlfive acres in some areas to protect significant fish habitat (Figure 3); o Regulations: Adoption of development controls including: -Establishment of buffers of waterside vegetation to protect streams and wetlands, -floodplain development and clearing limits, and -Requirements that new developments install improved water quality and stormwater control facil Hies: o Education and Incentives: Initiation of education and incentive programs to encourage public participation in stream protection; o Stream Steward: Establ1shment of a new 'Stream Steward" position to conduct education and cHizen involvement programs', facilitate project installation, and monitor basin management activities in the Soos Creek Basin: o Enforcement aod Penalties: Increase of County Code enforcement and stronger penalties for code violations: • Monitoring and Plan Update: Conduct basin monitoring to evaluate the program's long-term success and identify changing conditions that require adjustments in basin management. o Projects: Installation of stream improvement projects including: -60 small-scale stream improvement projects, including projects for streambank stabilization and revegetation; fencing of livestOCk-damaged reaches, improvement of instream habitat diversity, removal of fish-passage barriers, and repair of channel alterations: and -thirteen flow and erosion~related projects with appropriate mitigation such as bank revegetation, onsite habitat replacement, and fish passage facili- ties, including: * one regional detention facility to control flooding and erosion on, Soosette Creek: * a channel enlargement project to reduce flooding and improve habitat on Little Soos Creek: * a project to stabilize an eroding streambank of Big Soos Creek below a County road: - 4 - , , ( ===~==~~===~===============================~=================================== SUMMARY OF RECOMMENDED PLAN AND ITS IMPACTS ENVIRONMENTAL IMPACTS OF RECOMMENDED PLAN =============================================================================== * larger or parallel culverts· at SE 240th St., 132nd Ave. SE, SE 269th St., 120th Ave. SE and Petrovitsky Road, and 164th Ave. SE to reduce flooding and improve fish passage; * two flood-channel stabilization and protection projects on Upper Big S,oos and the Meridian Valley tributary; , * two detailed studies of RID alternatives on the Soosette and Meridian Valley tributaries; * raising of two flood-prone County roads; and * tlghtllne pipes to convey all or part of the water down steep eroding slopes at four sites (Figure 4). BASIN PLAN IMPLEMENTATION COST AND SCHEDULE The estimated cost of the recommended projects is $5.4 mill Ion. The costs of Implementing the plan's 50 other recommendations ranges from $1.3 million for staff and start-up costs In the first year to $478,600 In annual costs for ongoing basin management programs. If the recommendations under the Surface Water Management (SWM) Division's responsibility were funded using existing SWM revenues from the baSin, plan implementation would span 16 years during which property and resource damage would continue • . ". To shorten the implementation period to five years, a basin-specific surcharge Is recommended to be considered during King County Council review of the SWM Program In 1990/91. If this surcharge is adopted, the SWM fee for a single family residence during the five year Implementation period would range from $77 In the first year to $59 for the second through fifth years compared to the current fee of $29 per year. After five years, a permanent $3 Increase in the $29 fee could pay for continuing basin management programs. ENVIRONMENTAL IMPACTS OF RECOMMENDED PLAN NO-ACTION ALTERNATIVE If no action is taken, flows will more than double .in some reaches and human alteration of the stream system will increase as the basin reaches build-out conditions. These flows will worsen property damage and safety hazards due to flooding and erosion. The predicted consequences of these changes include a doubling of the amount of sediment eroded and transported in the malnstem, decreased beneficial use of water due to degraded water quality, and eventual reduction in fish populations due to aquatic habitat damage. BASIN PLAN IMPACTS In the long term, the watershed management measures in this plan are expected to have substantial positive environmental effects. Individual plan recommen- - 7 - =============================================================================== SUMMARY OF RECOMMENDED PLAN AND ITS IMPACTS ENVIRONMENTAL IMPACTS OF RECOMMENDED PLAN =================================~============================================= dations, however, could have some localized negative environmental impacts. Proposals for .low densHies,floodplain encroachment limHs, onsite RID stan- dards, clearing restrictions, vegetated waterside buffers adjacent to streams and wetlands, increased code enforcement and penalties, and incentives for resource protection would reduce future peak flow increases, and consequently . would reduce erosion and aquatic habitat damage. Limits to livestock access to streams would reduce streambanle erosion, resulting in reduced sedimentation of spawning gravels. Proposed education programs and water quality requirements for onslte RID facilities would reduce water quality degradation, resulting In reduced Impacts on beneficial uses, Including aquatic habitat. Water-.quality degradation also would be reduced through aquatic habltatlwater quality enhance- ment projects. Increased review of onslte septic systems In areas with highly Infiltrative soils also could reduce the risle of surface and ground water pollu- tion. WATER The proposed regional RID facility and any RID facilities that are recommended after detailed study of alternatives would reduce downstream peak flows and, as a consequence, reduce downstream flooding and erosion. RID facilities In wetlands could Improve downstream water quality through the settlement of sedi_ ments and attached pollutants but as a result could degrade water quality In the wetland. These facilities also would create an Instream Impoundment, affecting sediment deposition patterns and potentially degrading upstream aquatic habitat. . EARTH Construction-related erosion and sedimentation would occur during installation of tightline and conveyance pipes, construction of RID facilities, and banle stabilization. Once complete, however, these improvements would reduce channel scour and banle failures by reducing.peak flows or bypassing erodable areas. Regional RID facilities would change sediment transport and deposition patterns which could cause sediment to settle In the impoundment area and to be resuspended periodically and depOSited downstream. PLANTS AND ANIMALS The outlet structures for the proposed instream RID facility and facilities that are recommended for study may be impassable to fish during flood events. These structures WOUld. be impassable no more than ten percent of the time during the months of adult sa.lmon migration. These facilities would affect primarlly resident fish because the proposed instream ponds are either outside or at the upper limits of the anadromous zone. The instream detention sites may strand juvenile and adult fish as flood flows recede. Sediment could settle in spawning gravels in impounded ·reaches. In wetlands used for RID facilities, the increased water elevation and greater variability may cause a shift in the diversity, numbers, and community structure of plant and animal species. Instream habitat may be disrupted temporarily by the noise, erOSion, and acti- vity associated with construction. - 8 - =============================================================~================= SUMMARY OF RECOMMENDED PLAN AND ITS IMPACTS ENVIRONMENTAL IMPACTS OF RECOMMENDED PLAN LAND AND SHORELINE USE Local Increases In floodplain width would occur In Soos Creek Park and on undeveloped land In other areas. Proposed regulatory changes that address these Increases and other proposals to protect stream corridors, maintain lower densities, limit clearing, and protect regionally significant aquatic habitat; areas would limit the opportunity for development in flood-prone areas. Density limits would reduce the density of land use in substantial areas within the system. These limits apply In some areas designated as urban on the- Comprehensive Plan map and conflict with zoning in some areas. The limits would reduce some landowners' abilities to develop land to higher densities, and thus may have an economic Impact on these private landowners. Residential areas adjacent to project sites may be disrupted temporarily by construction-related traffic and noise. Ongoing disruption of adjacent areas would occur during faclljty maintenance activities. Shoreline access at some project sites also would be limited. TRANSPORTATION Intermittent congestion of neighborhood streets and arterials may occur during construction of projects. Temporary traffic disruption may occur during construction of the two road-raising proJects, but blockage during flood events would be eliminated. PUBLIC SERVICES AND UTILITIES Regional RID facilities and subbasin-specific onsite RID requirements would increase the County's maintenance-responsibilities. However, County programs already are established to maintain existing and new RID facilities. Land use and regulatory proposals would require County administration, including review of development proposals, inspection, and enforcement. -11 - c ( \ ( ( Current and Future Conditions , i =======:====================================~===============:=========:===:==== CURRENT AND FUTURE CONDITIONS DESCRIPTION OF WATERSHED AREA ===========:==:=::::===:======:=====:::==:=:=====:==::====:====:====::=======:= CURRENT AND FUTURE CONDITIONS: . Affected EnVironment DESCRIPTION OF WATERSHED AREA LOCATION The Soos Creek system lies In south King County, north and east of the Green River and southeast of the City of Renton. Big Soos Creek originates in the northeast corner of the glacially molded upland known as the Covington Drift Plain and jotns the Green River just east of Auburn. Covington and Jenkins Creeks are its main tributaries. STREAMS The Soos Creek system consists of mainstem Big Soos Creek and some 25 tributaries. The system has over 60 miles of stream and drains an area of approximately 70 square miles (44,800 acres) (Figure 5). All major tributaries in the Soos Creek system have similar physIcal characteristics. All drain flat to rolling terrain in the upper baSin, converging below River Mile (RM) 5.0 of Big Soos Creek. Many reaches of the upper plateau flow through extensive wetlands where pools are deep and velocities slow. The upper sections of 81g Soos are characterized by heavily wooded riparian corridors Interspersed with pastures and increasing reSidential development. Below RM 5.0, the gradient increases sharply as the stream flows through a deep canyon with long riffles and sparse pools. In these lower reaches, Big Soos Creek varies between 30 and 40 feet in channel width. Surface water in the Soos Creek system is carried largely in natural stream channels, typically with culvert crossings in the basin's upper regions and bridge crossings in the lower. The Soos Creek Basin has no regional retentionl detention (RID) facilities, but there are individual' detention ponds on platted and commercial building sites • . , WETLANDS The wetland system is quite extensive and includes all classes of freshwater wetlands--predomlnantly open water, scrub-shrub, and forested, with some emergent marsh. wet meadow, and bogs. The King County Wetland Survey and Basin Reconnaissance Report list over 225 wetlands In the Soos Creek system--a total of 2,076 acres, or about 4.8 percent of the land area in the basin (King County, 1986, 19B7a, 19B7b). Most wetlands of the Soos Creek system are "rlparlan"--assoclated with streams-- and are located on the flat or gently. rolling upper plateau of the watershed. In the Jenkins and Covington Creek Basins, much of the ~pper plateau Is underlain by varying depths of outwash material over till soils. The water table In this area often Is close to the surface. As a result, small pocket wetlands appear where potholes and swales intersect the groundwater table. In the upper Jenkins Creek Basin, for example, the headwaters of many streams are -13 - ====================================:========================================== CURRENT AND FUTURE CONDITIONS DESCRIPTION OF WATERSHED AREA =============================================================================== small, linear wetlands that formed in glacial troughs. As these streams travel toward the mainstem, many disappear Into porous gravel depOSits, only to reappear as wetland pockets farther downslope. LAKES The lakes of the Soos Creek system--Lake Youngs, Lake Meridian, Shadow Lake, Lake Sawyer, Lake Wilderness, Pipe Lake/Lake Lucerne, Ginder Lake, Ravensdale Lake, and Lake Morton--are used primarily for recreation and aestheti c· enjoyment. Six of them have boat ramps, and County parks lie on the shores of Lakes Meridian; Sawyer, and Wilderness. CURRENT AND FUTURE LAND USE Overview The north and west portions of the Soos Creek Basin west of Big Soos Creek have a pattern of urban density subdivisions, commercial centers, and scattered single-family homes. The most developed areas are along Kent-Kangley Road and near the western boundary with ·Kent and Renton. To the west of Big Soos Creek and south of Kent-Kangley Road, the Soos Creek Basin Is predominantly rural, with small farms and scattered residences. The Jenkins and Covington Creek BaSins, In the south and east parts of the Soos Creek system, mainly contain hobby farms and rural residences. Second-growth fore·sts are common. Sand, gravel,. and Clay are mined in the hills east and northeast of BlaCK Diamond, and coal is mined nea·r the northeast corner of Ginder Lake. The major developed areas surround Lakes Wilderness and Pipe/ Lucerne, the communities of Covington and Ravensdale, and the City of Black Diamond. Although much of the Soos Creek area remains rural, its population growth, number of SUbdivided lots, and permits for residential units show It to be one of the fastest-growing areas In King County. The late .1970s saw Increased devel- opment, particularly In the western Soos Creek Basin, and the effects of urban- Ization on surface water are already evident. Greater development promises to exacerbate effects such as Inc.reased flows and consequent erOSion, and human alteration of streams and wetlands.

WATER HYDROLOGY .AND HYDRAULICS Introduction The Soos Cree~ system is hydrologically complex with many la~es, wetlands, and interactions of surface water with groundwater~ Existing development in the basin ranges from rural to high-density,urban. A number of flow-related prob- lems have been associated with this urban development •. Understanding the hydrologic mechanisms behind these problems is the ~ey to solving them and pro- vides the basis for predicting where other surface water problems will occur as development continues. This section discusses th~ hydrology of the Soos Cree~ system under existing (1985) land use and future build-out conditions .in the absence of recommended mitigating measures. The relevant runoff mechanisms and factors that affect the Soos Cree~ Basin are discussed first, followed by a description of the basin hydrology and hydraulics under 1985 land use, the conditions under future build- out land use, and a list of specific flow-related problems. Runoff Mechanisms The hydrology of the Soos Cree~ system was characterized by many field visits, the use of a rainfall/runoff simulation computer model, and a hydraulic computer model. The Simulation model used was the Environmental Protection Agency's Hydrologic Simulation Program Fortran (HSPF). HSPF was used to portray the hydrology of the baSin under current conditions and examine the effects of build-out conditions on hydrology. The U. S. Army Corps of Engineers HEC-2 hydraulic model was used to compute flood plains and determine the extent of flooding in flood-prone areas •. Input parameters for the models used in this analysiS are outlined in the Soos Creek Basin Calibration Reports (King County, 1987c) and are available upon request from King County. Soils were grouped into three broad categories for hydrologic purposes: outwash, till, and wetlands (see Geology section for a complete discussion of soils). Outwash soils consist of sand and gravel deposits that have high infiltration rates. Rainfall in these areas is quickly absorbed and percolates to the groundwater table. Creeks draining these areas typically Intercept the groundwater table and receive most of their flow from groundwater discharge. The response in the creeks after a storm is therefore slow, with the peak flow In the creek often occurring up to several days after a storm. Ttll soils are consolidated, contain large percentages of silt or clay, and have low percolation rates compared to the outwash soils. Only a small fraction of -17 - :============================================================================== CURRENT AND FUTURE CONDITIONS WATER =============================================================================== .the Infiltrated preclpltat10n reaches the groundwater; the rest moves laterally through the thin surface soil, often re-emerglng at the base of hlllslopes. This shallow, subsurface, lateral movement of flow Is called Interflow. Interflow travels to the creek much faster than groundwater but slower than surface runoff. Till soils may become saturated In moderate to large storms and produce s Ignl fl cant amounts of surface runoff. The peak runoff rate from till: areas Is therefore typically much higher than from outwash areas. Wetland soil s remain saturated throughout much of the year. A 1 though the runoff from wetland areas Is typically constant In the summer, during the wet season they prOduce sl_gnl flcant amounts of surface runoff. Three types of cover were considered In analyzing the hydrology of the Soos Creek system: forest, grass/pasture, and Impervious. Runoff from forested areas produces the least amount of surface runoff. Forest cover Is most significant In till areas because It breaks up the structure of the till soils .and allows more Infiltration to Occur. Interception and evapotranspiration, which Influence-autumn, spring, and summer storms the most, Is greater In forested areas than In the· other cover categories. GraSs-ed areas produce more surface runoff-than forested areas. Because grass Is .shallow-rooted, It does not contribute to Infiltration as forested cover does. Grassed areas therefore saturate more quickly and produce more overland flow in large storms than forested areas. Impervious areas produce the most surface flow, because the Infiltration rate in impervious areas is zero. The combination of forest cover and outwash soil produces the lowest peak flows, with grass-covered outwash producing the next lowest, then forested till, grassed till, and finally impervious cover. Peak flows from wetland salls are variable depending on when the storm occurs. In winter when the wetland soils are saturated, they produce high peak.s similar to grassed till areas. In summer the wetlands Infiltrate preCipitation and the runoff characteristics more closely resemble forested outwash. Receiving creeks, lakes, and wetlands also affect the runoff characteristics from -0. given area. These features store flows and release them more slowly, thus reducing the flow peak.. The degree to which these flows are reduced depends upon the roughness, slope, size, and shape of the channel. The most- sensitive of these parameters Is channel size. Thus wetlands and lakes are typically more effective than a typical stream channel at reducing flow peaks. Hydrology Under 1985 Land Use Introduction: Flows from the various tributaries in the Soos Creek system were quantified using the HSPF model. It was desirable to examine the hydrologiC response of the basin under as many different storm and lOW-flow conditions as possible. To do this, the longest suitable rainfall record available was Input to the HSPF model. This record was collected at the gage at Seattle-Tacoma International Airport. The length of the record Is 38 years, spanning October -18 - I . :::============================================================================ CURRENT AND FUTURE CONDITIONS WATER 1948 through September 1986. ·The record contains several high-intensity storms, as well as several drought years. The land use was held constant at 1985 levels throughout the simulation (F1gur,e 6). Figure 8 shows the results of the simulation run (flows for other intermediate' frequencies are listed in the Background Information and References section). The HSPf model simulates flows at the outlet of each subbasin. Flows have been listed in terms of probability, or flow frequency. For example, in Subcatchment S16, the 100-year flow is 59 cubic feet per second (cfs). This means that a flow of 59 cfs has a one percent probability of occurring in anyone year. Flow frequencies were computed using a log-Pearson analysis (Water Resources Council, Bulletin 17a, 1977). General Trends: Flows in the more densely developed areas of the Soos Creek Basin are higher than those·farther east in the Jenkins and Covington Creek Basins. Areas with the highest flow rates relative to the area draining to them are areas in the western part of the basin where development is heaviest. These areas include: the Meridian Valley Tributary (Subcatchment S8), upstream of lake Meridian (Subcatchment lM3) , and Soosette Creek (Subcatchment STl-ST5). Natural features that presently attenuate high flows from urbanization include: the wetlands along the main stem of Big Soos Creek (Subcatchments S16, S15, S13, Sll, S9, and S7), lake Meri~ian (Subcatchment lM2), and Soos t.reek Wetland 50 at the outlet of Subcatchments ST4 and ST5. Peak flows from the Jenkins and Covington Creek Basins are much lower than those in the Soos Basin, primarily due to the undeveloped state of the basin, the numerous lakes and wetlands,· and the large areas of highly infiltrative outwash soil. Jenkins and Covington Creeks respond slowly after a storm event, with a gradual rise and fall in flow typical of a groundwater-dominated basin. Hydrology Under Buildout Conditions Introduction: The effects of future land use on basin hydrology were examined using the HSPF model. The future land use scenario that was assumed for analy- sis was buildout conditions (Figure 7), defined as the densest use permitted under existing or proposed land use plans and zoning. This analysis assumed that no human-made flow controls were present. Under future ·conditions, flood peaks with a recurrence interval of two years (the 2-year flow) are predicted to increase up to 3.5 times, with an average increase of 1.B times over 1985 land use. Peak flows at the lOO-year level have an average increase of 1.5 times over 1985 (Figure 9). A particular flood stage will recur more often, on average, but each event of a given frequency will occupy less time. This corresponds with the notion of "flashy" urban streams. ·There are 1985 flow data for 56 of the 58 subcatchments. Of these, 28 are predicted to have future flows occurring more frequently than every 25 years that equal or exceed the SOD-year flow modeled under current conditions. In the little Soos drainage basin (Subcatchments LS4-lS1), the SOD-year flows under 1985 land use are predicted to occur on average every other year. -23 - =============================================================c================= CURRENT AND FUTURE CONDITIONS WATER =============================================================:=:=:=====:=====:= Flow Increases Due To loss of Forest: Figure 10 shows future peak flows. Generally, the subcatchments that change from forested land cover to urban uses on till soils are predicted to have the greatest increases in peak flows. The subcatchments in the upper Soos Creek Basin surrounding lake Youngs (Subcatchments 514, 512, lS4, and lS3), the area downstream of Shadow lake in Jenkins Basin (Subcatchments J5 and J4), and the area in the lower Covington Basin (Subcatchment C8) are of this type. Peak flows in some of these areas tripled despite the fact that land use densities are relatively low (one unit per acre or less in most cases). These areas are therefore the-illost sensitive to increased peak flows caused by. development. Flow Increases Due To Increased Impervious Area: Impervious surfaces are the most influential hydrologic parameter in determining how much flows will increase from existing to future conditions. Incr~ases in peak flows under 1985 land use in the following areas may be attributed to large increases in Impervious areas associated with urbanization: lake Meridian Tributary (Subcatchments lM3, and lMl), Soosette Tributary (Subcatchments ST5, ST4, ST3, ST2, and STl), South Fork Jenkins Creek (Subcatchments SF3, SF2, and SFl), and Ravensdale lake (Subcatchment C12). System Effects of Increased Peak Flows: Although flows are expected to increase dramatically In the locations described above, the system-Wide effects are not expected to be as severe due to the mitigating effects of natural features in the basin. These features include extensive riparian wetiands, lakes with large volumes, and infiltrative soils. Increased flows will increase the magnitude and frequency of water surface elevation in lakes and, wetlands. Because the volumes of the lakes in the Soos Creek Basin are large compared to the area draining to them, the fluctuations in water elevation under future land use were found to be small, typically two feet or less. Therefore, frequent flooding of lake-side structures should not be a problem under future land use. The effects of increased flows due to urbanization will be greater on wetlands. Because wetlands typically have smaller volumes than lakes, Increased flows will cause greater fluctuations of water depth there than in lakes. This fluctuation can cause changes in plant species, and ultimately result in more open water (see Plants and Animals section for a detailed discussion of wetlands). Other HydrologiC Effects of Increased Impervious Area: Although the HSPF model displays particularly well the peak-flow increases that accompany urbanization, other changes will occur as well. Most significant will be dlstruptlon In the groundwater regime, particularly the loss to storm flow of water that used to Infiltrate and recharge groundwater reservoirs. In the Jenkins and COVington Bas'ins in particular, where streams, riparian wetlands, and shallow. groundwater form a unlfed system, disruption of recharge may have long-term consequences, particularly the lowering of wetland water levels and the reduction of non-storm stream flows. .,. I ) ", I - CURRENT AND FUTURE CONDITIONS WATER e===::=:=========:=:====::=:====:=:::=::::::::==:===:============:===::======== Area-Specific Effects Upper Soos Creek: Increased fl~ws from Subcatchments S14, S12, and S10 are attenuated by wetlands located along the mainstem in Subcatchments S13 and SII. Because the tributaries in these subcatchments flow through deep gullies, flooding is not expected to be a problem in the future: Further, erosion is not expected to be rapid because the channels are underlain by till. Peak flows in the headwaters of the Lake Meridian Tributary are buffered by Lake Mel-1dian •. Although flows downstream of the lake (Sub catchment LMl) are predicted to more than double, the magnitude of flow is still small compared to the capacity of the channel to convey the flow. There have been reports of -flooding downstream of the lake in Subcatchment LMl; however, this is a result of an inadequate outlet structure on an onsite detention pond and is not due to peak flows from upstream. Predicted flow increases in this tributary are therefore not considered problematic. Specific flow-related problems in the Upper Soos Basin are as follows (see Figure 11 for locations).

Little SODS Creek: Increased flows in little SODS Creek will exacerbate an existing flooding problem at SE 264th St. (Figure 11). Increased flows are expected to worsen erosion in the lower reaches of this tributary (Subcatchment LSI) and increase sedimentation at the confluence with the mainstem. -31 - :============================================================================== CURRENT AND FUTURE CONDITIONS WATER ===========================================c=================================== Map Reference (Figure 11) Location E.

Jenkins Creek: Flow increases In the south fork of Jenkins Creek (Tributary 0088) are not expected to produce flooding problems despite the hlgh- denSity areas (three to seven units per acre) tributary to this reach. The extensive outwash deposits and the riparian wetlands along the creek attenuate peak flows such that future flows Increase by 50 percent over 1985 levels below Subcatchment SF1. Instream erosion In this area also Is not expected to be a. factor because of the low channel gradients. Slml1arly. high flows from Subcatchments J10 and J8 are attenuated by the extensive wetland system along the stream In Subcatchment J7 and therefore are not considered to be problematic.

These basinwide recommendations apply throughout the Soos Creek system unless superseded by area-specific" requirements. AREA-SPECIFIC RECOMMENDATIONS UPPER SOOS BASIN: Big Soos Creek and Its Tributaries North of RM 4.6 Introduction The Upper Soos Creek area is one In transition, with urban-related problems in its west and north reaches and rural problems In the east. Big Soos Creek and its seven northern tributaries are low-gradient streams with many riparian wetlands. Big Soos Creek flows through Soos Creek Park from about RM 7 to 13. The northwestern portions of the upper Soos Creek Basin are developing rapidly and most of the area is expected to develop to urban densities of one unit per acre or more. Surface water problems in this area include flooding and high peak flows, increased future peak flows and flooding, and aquatic habitat damage. Recommendations (Figure 21) Flooding: Flooding of apartments near SE 176th St. and County roads SE 256th St. and 148th Ave. SE occurs. To reduce this flooding, the following projects are recommended: • • UPPER SOOS CREEK CHANNEL AND CULVERT IMPROVEMENT (Project 5401a), a conveyance enlargement and culvert Improvement project to reduce roadway and apartment flooding.

Any future loss of the natural storage capacity of wetlands and floodpla ins wi 11 aggravate these probl ems. However ,--the damage from Increased flows should not be as significant where large lakes, such as Lake Meridian, can store additional runoff. Proj~cts 5401a, 5417, 5421a/5422, 5409 (see above) will be sized to control future flows. In addition to the basinwide recommendations (see Basinwide Recommendations section), the following actions are recommended to reduce habi- tat damage and these future flow increases: • LAKE YOUNGS FOREST RETENTION (AS1). The approximately 830-acre Lake Youngs Watershed should be retained In forested land cover. Because no acquisition is possible at this time, King County may benefit from an option to purchase at a later date or other long-term preservation agreement with the City of Seattle. Implementing Document: Interlocal Agreement, King County Open Space Plan, or Soos Creek Community Plan. o UPPER 5005 RURAL DENSITIES (AS2). Areas deSignated as rural-residential In the 1985 King County Comprehensive Plan should be retained In rural den- sities in the upper Soos Creek Basin from Big Soos Creek east toward the Little Soos Basin (Subcatchments 57, 59, SID, 512, and 514). Implementing Document: SODS Creek Community Plan. o UPPER 5005 REDUCED ONSITE DETENTION STANDARDS (AS3). In the Lake Meridian subcatchment (LM2), onsite R/D facilities in conjunction with single-family development (seven units/acre or less) may be designed to a reduced 2-year 24-hour detention standard if the relea~es can be conveyed to the lake without causing flooding or erosion. Implementing Document: King County Surface Water Design Manual appendix. Aquatic Habitat Damage: Aquatic habitat has been damaged by channelization, livestock trampling, devegetatlon, poor water quality, debris dumping, erosion and sedimentation, and removal of large organic debris (logs and stumps). The following projects are recommended to address these problems: o PROJECTS 5450, 5451, 5452, 5453, and 5459, to restore Instream habitat diversity. Estimated costs*: $165,000; $10,000; $10,000; $10,000; and $1,250 respectively. * Aquatic habitat and water quality improvement project costs reflect construction costs only. -81 - =============================================================================== RECOMMENDED PLAN AREA-SPECIFIC RECOMMENDATIONS =============================================================================== o PROJECTS 5454, 5458, 5470, 5471, to limit horse and livestock access to streams. Estimated costs: $200; $200; $1,500; and $12,200 respectively • • PROJECTS 5466 and 5467, to revegetate streambanks. Est~mated costs: $2,750 and $13,000 respectively. • PROJECTS 5474, to remove debris from streams. Estimated cost: $1,400 • • PROJECTS 5460 and 5482, to restore natural channels and improve water quality. Estimated costs: $86,50Q_ and $178,000 respectively. Discussion The goals in the Upper Soos Creek Basin are to reduce flooding of structures and roads-, retain the integrity of stream channels, and protect the remaining aquatic hab1tat. Key to thes,e goals is the reconmendation to retain rural den- sities in the eastern half of the area (Subcatchments 57, 59, 510, 512, and S14) and to preserve the forest cover in the Lake Youngs watershed. The main resource in the Upper Soos area is the extensive riparian wetland system along the mainstem. This wetland, considered important system-wide, currently provides excellent rearing habitat for salmonids, wildlife habitat, and aesthetic benefits to users of Soos Creek Park. During 1989, the King County Natural Resources and Parks Division completed five projects to remove debriS, provide stormwater detention, revegetate streambanks, and provide stream viewing areas. These habitat~related projects in and near the park will improve both the wetland habitat and the quality of water entering this wetland from the east. One additional projeCt, the raising or culverting of the SE 216th St. and SE 224th St. roadbeds, was evaluated during basin plan preparation and found to be ineffective in remedying local sedimentation of spawning gravels and reducing saturation of trails. Future peak flows entering the malnstem-of Soos from the eastern tributaries are predicted to nearly double, even under the Recommended Plan. This Increase In flows is comparatively high. However, flooding In these tributaries is expected to be minimal since they flow through fairly confined channels with adequate conveyance. Increased stream erosion from these channels and subsequent deposi- tion in the mainstem wetland,.however, may pose local problems as development progresses. The high flows entering from the eastern tributaries are subsequently buffered by the large storage capacity ;n the mainstem wetland system, resulting;n a small (15 percent) increase in flows over 1985 land use at the wetland outlet. These increases should not significantly expand floodplains nor harm aquatic habitat in the wetland, although some wetland expansion Is expected. The projects and regulatory solutions proposed in the Upper Soos Creek area reduce flooding frequency at three existing local flooding sites, protect streamside wetlands along the malnstem of Big Soos, improve aquatic habitat, and reduce new development-related problems. -82 - =============================================================================== RECOMMENDED PLAN AREA-SPECIFIC RECOMMENDATIONS ==================~=======================================~==================== Project 5401a will address a local flooding problem in the headwaters of Big Soos Creek by increasing the channel and culvert capacity in the flooded area. Project 5417 will raise the ro~d elevation of SE 256th St. above the 25-year floodplain. This project will not appreciably affect flows or floodplain elevations In the creek. Project 5421a/5422 proposes to replace the culvert crossing SE 240th ·St. with a larger capacity culvert and stabllze the downstream channel. The project will reduce flooding that currently occurs at a 2-year frequency to a 25-year fre- quency. All .culverts will be replaced to WSDOF standards··for fish passage. Project 5409 proposes to study alternatives to reduce flooding downstream of Clark Lake to SE 240th St. This project should be designed In conjunction with Projects 5421a and 5422. Impl ementatlon Table 5 summarizes the Upper Soos Creek Basin recommendations, their costs, and Implementation priority. Implementation of recommendations within the jurisdiction of other agencies and King County divisions will be negotiated with these agencies. Cost estimates or schedules will be refined during these negotiations. Recommendations to be implemented by the SWM Division are scheduled according to their rank and the availability of SWM Program revenues ·for the Soos Creek area. · -83 - =============================================================================== RECOMMENDED PLAN AREA-SPECIFIC RECOMMENDATIONS =============================================================================== TABLE 5 UPPER SOOS IMPLEMENTATION SUMMARY Agency Initial ID Involv.e-Implemen-Imple- I ment Benefit tation Cost mentation .J.!..

Alternative solutions for area-specific problems in six regions of the Soos Creek system are in the first section. The second section Identifies and compares alternative solutions to basinwide problems. Finally, the generalized environmental Impacts of these alternatives are discussed. AREA-SPECIFIC ALTERNATIVES INTRODUCTION The Soos Creek Basin Plan encompasses an area w1th a diverse range of geologic terrains,aquatlc environments, and land use activities. In the western part of the Soos Creek system, rapid urban development has contributed to high flows and consequent flooding, bank erosion, and aquatic habitat problems. In the eastern .. part of the system, which Includes virtually all of the Jenkins and Covington Creeks Basins, low levels of existing development and favorable terrain have resulted in some of the highest quality fish habitat In King County. To address the specific concerns In these diverse areas, this section Identifies and compares alternative solutions to problems in six regions of the Soos Creek system. These regions include (progressing from the headwaters downstream) the Upper Soos, Little 5005, Jenkins, COVington, Soosette, and Lower 5005 Basins. UPPER 5005 BASIN: Big 5005 Creek and Its Tributaries North of RM 4.6 Flooding Issues and Alternatives Apartment Flooding: Periodic flooding of apartments near 174t~ Ave. SE causes property damage. To protect these apartments from future flow increases, the following actions were conSidered: o NO ACTION, allow periodic local flooding of apartments to continue. o 5005 CREEK WETLAND 1 REGIONAL DETENTION POND (Project 5401), a regional detention pond on Tributary 0072 at RM 14.3. Estimated cost: $322,000 (Figure 32). o UPPER 5005 CREEK CHANNEL AND CULVERT IMPROVEMENT, (Project 5401a), a conveyance enlargement and culvert improvement project in upper Tributary 0072.

To provide 25-year flood protection under future land use conditions, the following actions were considered: o NO ACTION, allow periodic flooding of SE 256th and 148th Ave. SE to continue. • SE 256TH/148TH SE ROAD RAISING (Project 5417), raising of the SE 256th St • . bridge and the road elevation at 148th Ave. SE. Estimated cost: $230,000. o MIDDLE· 5005 WETLAND 30 REGIONAL DETENTION POND (Project 5417a), a regional detention pond on Tributary 0072 at SE 148th Ave. to reduce flooding of SE 256th St. Estimated cost: $464,000 Shopping Center Flooding: Periodic flooding of the Meridian Valley Shopping Center and SE 240th St. causes property damage and traffic safety problems. To protect the shopping center and road from unacceptable flooding under future land use conditions, the following actions were considered: • NO ACTION, allow periodic flooding of Meridian Valley Shopping Center and SE 240th St. to continue. • MERIDIAN VALLEY DETENTION AND CULVERT REPLACEMENT (Projects 5421/5422), a regional detention pond, channel stabilization, and culvert enlargement on SE 240th St. near the 132nd Ave. SE intersection. Estimated cost: $280,000. • MERIDIAN VALLEY CHANNEL AND CULVERT IMPROVEMENT (Project 5421a/5422), a combination of channel stabilization and culvert enlargement on SE 240th St. near the 132nd Ave. SE intersection. Estimated cost: $455,000. • 5005 CREEK WETLAND 20 REGIONAL DETENTION POND (Project 5407), a regional detention pond on Tributary 0091B in a #2-rated wetland to reduce flows and roadway flooding. Estimated cost: $517,000. • CLARK LAKE TRIBUTARY HYDROLOGY STUDY (Project 5409), an engineering study of Tributary 0091A from 132nd Ave. SE to the headwaters to evaluate alternatives for control of flooding on this tributary. To be done in conjunction with design of 5421a/5422. Estimated cost: $20,000. Comparison of Impacts: (See Generalized Impacts of Alternative Solutions section for more detailed impacts.) The Upper Soos Conveyance Alternative (5401a) would effectively reduce local apartment flooding by increasing storm- water conveyance capacity during high flows. The Upper 5005 Detention Alternative (Project 5401) would also be effective in reducing flooding. However, this alternative could change the wetland's plant and animal species by changing water levels and would not have the storage capacity to reduce flows much beyond the apartments. . Flooding of SE 256th St. would be effectively reduced by either raising of the road (Project 5417) or upstream detention (Project 5417a). However, detention (Project 5417a) could impact park uses and aquatic habitat by creating more sedimentation resulting in wetland and floodplain expansion. -159 - =============================================================================== ALTERNATIVE SOLUTIONS AND IMPACTS AREA-SPECIFIC ALTERNATIVES ===========================================================~=================== The Meridian Valley Detention and Culvert Alternative (Project 5421/22) would not have sufficient capacity to adequately reduce flooding and downstream ero- sion. This alternative would effectively reduce flooding of Meridian Valley Shopping Center and SE 240th St. but must be implemented in combination with downstream bank stabilization and the Clark Lake Study Alternative to reduce downstream erosion and degradation fish habitat. The Soos Creek Wetland 20 Detention' Alternative (Project 5407) would reduce peak stream flows downstream to SE 240th St. but is on a tributary that contributes only a small part of the stream flows, at the floodll).g site. Thus this facility would not be effective in reducing flooding, although It would reduce periodic high flows 'for the upper 0.5 mile of Tributary 0091B. The Clark Lake Tributary study would be done In conjunction with the design for Projects 5421a/5422. The study 'would identify sources of flooding problems and evaluate solutions 'to problems observed in the reach between SE 240th St. and the Big Soos Creek confluence during the January 9, 1990 storm. If the No-Action Alternative is selected for any of the three flooding problems, periodic flooding of an apartment building, shopping center, and roads would continue. As a result, the use of these facilities would be limited during floods, and property damage and safety hazards would continue. Preferred Alternatives: The,Soos Creek Wetland outlet channel Improvements (Project 5401a) Is the preferred alternative to the apartment flooding at 174th Ave. SE, because it would effectively reduce flooding without creating wetland impacts. SE 256th St./148th Ave. SE"Road Raising (Project 5417) is the preferred alternative for reducing flooding of SE 256th St. and 148th Ave. SE. This pro- ject would reduce flooding and have little impact on surrounding wetlands, floodplain elevations, or adjacent park uses. Finally, the Meridian Valley Detention and Culvert Enlargement (Project 5421a/22) and Clark Lake Tributary Hydrology Study (Project 5409) together are the pre- ferred alternative for reducing flooding of the Meridian Valley Shopplng"Center and SE 240th St. This alternative is preferred because it allows flooding and erosion problems throughout thIs reach to be evaluated together, resulting in solutions that reduce flooding and flow-related erosion from the creek's head- waters to its confluence with Big Soos Creek. Future Fl ows Introduction: ErOSion, habitat damage, and more "frequent flooding are predicted as peak flows increase more' than two-fold in some areas. Much of these flow increases will result from the removal of forest growing on tnl soils. Any future loss of the natural storage capacity of wetlands and floodplains will aggravate these problems. However, the damage from increased flows should not be significant below large lakes such as Lake Meridian which store runoff and release it slowly. ' -160 - - =========================================================::========:=====:===:= ALTERNATIVE SOLUTIONS AND IMPACTS AREA-SPECIFIC ALTERNATIVES =====:=======:===================:====::======================================= In addition to the basinwide alternatives (see Basinwide Alternatives section), the following actions are considered so that future flooding is reduced and future flow levels are as close .to today's flows as feasible: • NO ACTION, areas would continue to develop at densities allowed by the King' County Comprehensive Plan, Community Plan, and zoning, as amended in the ' future. • CURRENT FLOODING PREFERRED ALTERNATIVES (Projects 5401a, 5409, 5417; and 5421aIZ2)., The stream improvement projects considered as solutions to current flooding problems will be designed to function under future land use conditions. • LAKE YOUNGS FOREST RETENTION (AS1). The approximately 830 acre La~e Youngs Watershed would be retained in forested land cover. Because no acquisition is possible at this time, the County may benefit from an option to purchase at, a later date or other long-term preservation agreement with the City of Seattle • • UPPER SOOS RURAL DENSITIES (AS2). Areas deSignated as rural-residential In the 19B5 King County Comprehensive Plan should be retained in rural densities in the Upper Soos Cree~ Basin. • UPPER SOOS ONSITE DETENTION STANDARDS (AS3). In the La~e Meridian subcatchment (LM2), onsite R/D facilities in new developments with single- family denSities of seven units/acre or less may be designed to a 2-year detention standard if the water can be conveyed to the la~e without causing flooding or erosion. Comparison of Impacts: (See Generalized Impacts of Alternative Solutions section for more detailed impacts.) Because the Rural Density Alternative (AS2) is consistent with the 1985 King County Comprehensive Plan, this alternative would be effective if It prevented future plan amendments to allow higher densities. This alternative (AS2) would be most effective If implemented in combination with the basinwide clearing limits (BW3 and CW4) (see Basinwide Alternatives section). This alternative would affect about 1,540 acres east of Upper Soos Creek toward the Little Soos Basin. Because of Lake Meridian's large volume relative to the flows entering it, the basinwide onsite RID sta'ndards (BW2, see Basinwide Alternatives section) are unnecessarily restrictive compared to the area-specific standard (AS3). Basinwide onsite RID standards also would increase the cost of private development more than the area-specific standards. However, facilitlei should not be designed to the 2-year standard if their releases would result in flooding or erosion before discharge to the lake. Although the Lake Youngs Forest Retention Alternative (AS1) is feasible only for the Lake Youngs Watershed where a large forested headwater area remains in public ownership, it would effectively reduce future flows in a subbasin that is very sensitive to deforestation-related flow increases. -161 - - =====~========================================================================= ALTERNATIVE SOLUTIONS AND IMPACTS AREA-SPECIFIC ALTERNATIVES =============================================================================== If the No-Action Alternative is selected, future peak 2-year flows would increase an average of 66 percent over 1985 levels. As a result, flooding of an apartment building, shopping center, and two roads; erosion; and aquatic habitat damage would continue, and likely worsen. ' Preferred Alternative: Because no alternative alone can effectively reduce future flows enough to protect stream channels and habitat, and reduce flooding, the Lake Youngs Forest Retention (AS1), Rural Densities (AS2), Current Flooding Preferred A lternati ves (Projects 5401a, 5409, 5417, 5421a122), and Reduc'ed Onsite Oetentlon Standards (AS3) Alternatives together are the preferred alter- native. Under the preferred alternative, average 2-year'peak flows are pre- dicted to be reduced by 74 percent of the predicted flows under the No-Action Alternative. Aquatic Habitat and Water Quality Introduction: Aquatic habitat has been damaged by channelization, livestock trampling, devegetatlon, poor water quality, debris dumping, erOSion and sedimentation, and removal of large organic debris. These observed problems are predicted to continue or worsen due·to development-related Increases in flow and human activity. In the future, surface water quality could be degraded by onsite septiC systems sited too near reaches with adjacent highly infiltrative soils and shallow groundwater aquifers. In addition to the Basinwide Alternatives, the actions listed below were considered to Improve habitat damaged by past human activity and reduce future habitat and water quality problems. Although the listed projects may have alternative design features, these features cannot be evaluated here because only minimal site data are available. As a result, the No-Action Alternative Is considered the only alternative to the projects. Any required evaluation of the Impacts of alternative design features will be conducted at the time of project design and Implementation. o NO ACTION, Allow aquatic habitat damage from livestock trampling, loss of forested streamside corridors, channel alterations, flows, and water quality degradation to remain. o AQUATIC HABITAT IMPROVEMENT. Current Floodln and Future Flow Preferred Alternatives (Projects 5401a, 5409, 5417, 5421a 22, AS1, AS2, and AS3 , these preferred alternatives are designed to reduce flows and thus reduce flow-related habitat damage. The Density Preferred Alternatives (AS! and AS2) also would reduce habitat damage caused by increased human intrusion into and alteration of riparian areas. Pro"ects 5450 5451, 5452, 5453, and 5459, to restore instream habitat diversity. Estimated costs: 165,000; 10,000; $10,000; $10,000; and $1,250 respectively. Projects 5454, 5458, 5470, and 5471, to limit livestock access to streams. Estimated Costs: $200; $200; $1,500; and $12,200 respectively. -162 - - =c===:=========:=====:=======:===:::===:=:==:=====:=::=======:================: ALTERNATIVE SOLUTIONS AND IMPACTS AREA-SPECIFIC ALTERNATIVES =========================================================================:===== Projects 5466 and 5467, to revegetate streambanks.

Projects 5460 and 5482, to restore natural channel s and improve water' quality. Estimated Costs: $86,500 and $178,000 respectively. Comparison of Impacts: (See Generalized Impacts of Alternative Solutions section for more detailed impacts.) livestock Fencing Projects (5454, 5458, 5470, and 5471) would restore damaged streambanks and reduce the potential for fecal coliform contamination of the stream system, but would reduce available grazing area compared to the No:Action Alternative. Projects 5450, 5451, 5452, 5453, and 5459 wOuld improve instream habitat diversity and reduce fish stranding In Soos Creek Park compared to the No~Action Alternative, but could result in temporary construction-related turbidity. Projects 5473 and 5474 would improve instream habitat diversity by removing debris from streams. Projects 5460 and 5482 would have temporary construction-related erosion inipacts,but would restore natural channels and improve water quality in the long term compared to the No-Action Alternative. Projects 5466 and 5467 would revegetate streambanks damaged by past human activity, thus reducing erosion and providing shade and other benefits of vegetation compared to the No-Action Alternative. The Current Flooding and Future Flow Preferred Alternatives (Projects 540la, 5409, 5417, 5421a/22, ASl, AS2, and AS3) would be designed to reduce current and futu-re flows, and thus reduce flow-related habitat damage compared to the No-Action Alternative. The DenSity Preferred Alternatives (AS1 and AS2) also would reduce habitat damage caused by increased human intrusion into and alteration of riparian areas. If the No-Action Alternative is selected, Identified aquatic habitat and water quality problems would continue and likely worsen. Aquatic habitat would continue to degrade due to increased flows, gre~ter human alteration of wetlands, stream channels, and riparian corridors, reduced aesthetic value of Soos Creek Park, and continued livestock-related damage. Preferred Alternative: IndiVidually the aquatic habitat Improvement projects have only I oca I benefits and impacts, but together they improve the overa 11 habitat diversity In this subbasin. As a result, all the aquatic habitat improvement projects are part of the preferred alternative. Control of flows by the Current Flooding and Future Flow Preferred Alternatives (Projects 5401, 5409, 5417, 5421a/22, AS1, AS2, and AS3) is preferred for reducing flow-related habitat damage. Basinwide Preferred Alternatives Except where superseded by the Area-specific Preferred Alternatives, the Basinwide Preferred Alternatives (see Basinwide Alternatives section) also would apply in the Upper Soos Basin. -163 - - ================================================~============================== ALTERNATIVE SOLUTIONS AND IMPACTS AREA-SPECIFIC ALTERNATIVES =============================================================================== LITTLE 5005 BASIN: Little Soos Creek and Its Tributaries flooding Introduction: Human alteration of the stream channel and construction In the' floodplain has caused almost annual flooding of four to six houses in the lower reaches. To protect these houses and two additional houses from the future 100-year flow, the following projects were conSidered: . o NO ACTION, Continued almost annual floodlng'of four houses. o LITTLE SOOS CHANNEL AND CULVERT ENLARGEMENT (Project 5416), a channel and culvert enlargement project at RM 0.6 and RM l~D. Estimated cost: $404,000 (Figure 33). o LITTLE 5005 REGIONAL DETENTION POND (Project 5416a), a regional detention .. pond on Tributary 0092 at RM 1.6. Estimated cost: $250,000. j o LITTLE 5005 HIGH-FLOW BYPASS (Project 5416b), an approximately one~ile-long pipeline to divert high flows to Big Soos Creek. Estimated cost: $2,000,000. o HOUSE PURCHASE (Project 5416c), County purchase of the six houses In the future floodplain. Estimated cost: $800,000. Comparl son of Impacts: (See Generalized Impacts of Alternative Sol utions sect ion for more detailed impacts.) The regional detention pond (Project 5416a) would be ineffective in reducing flooding due to site limitations, providing a 16 percent flow reduction only for future flows below the 2-year flow. The high-flow bypass (Project 5416b) would be effective in reducing flows In Little Soos Creek, but is costly, would transfer flow increases to Big Soos Creek, and would require extensive right-of-way acquisition along the stream corridor, disrupting several residences. Purchase of the houses (Project 5416c) would effectively reduce the exposure of residents to flooding but may be difficult to implement, is costly, and would not reduce erOSion or improve habitat in ·this channelized reach. If the No-Action Alternative is selected, the current flooding problems and resulting property damage in this reach would continue and likely worsen. Preferred Alternative: The Little 5005 Channel and Culvert Enlargement (Project 5416) is the preferred alternative because it would effectively reduce the flood damage, would cause only localized disruption of land uses and habitat, and is comparatively more cost-effective. Instream habitat and fish passage restoration is also possible with this alternative. Right-of-way costs would be relatively high. -164 - - Exhibit "E" Reconnaissance Report No. 2 Soos Creek Basin Petro Vista Level 1 Downs1ream Analysis RECONNAISSANCE REPORT NO.2 soas CREEK BASIN JANUARY 1986 Natural Resources and Parks Division and Surface Water Management Division King County~ Washington Department of Public Works Don laBelle, Director King County Executive Tim Hill King County Council Audrey Gt1Iger, District 1 Cynthia Sullivan, District 2 Bill :Reams, District 3 Lois North, District 4 Ron Sims, District 5 Bt1Ice Laing, District 6 Paul Barden, District 7 Bob Grieve, District 8 Gary Grant, District 9 Pari:s, Planning and Resources Joe Nagel, Director Surface Water Management Division Joseph J.

This development pattern bas not caused serious environmental damage or flooding" however, due to bighly pervious soils, an e~:tensive network of streams and wetlands tbat provide natural storage for storm .... ."ter runofr, and tbe fact that development has only recently accelerated in tbis basin. A1tbough the overaU severity of problems in the Soos Creek Basin ~ not great at the time of reconnaissance, several significant problems were identified and should be addressed. These include bank failures, channel erosion, flooding in some Iocatioas, and poor stream habitat. Recommendations to address these prob lems include efforts to 1) inform appropriate agencies of the reconnaissance findings, 2) n:evaluate specific policy issues regarding the management of 5UTCace water, 3) prepare a comprebensive basin plan, 4) coostruct the capital improvement projects evaluated with citizen advisory committee criteria, and 5) maintain or enhance habitat throughout the basin. II. INTRODUCTION: History and Goals of the Program P:SCB In 1985 the King County Council approved funding for the Planning Division (now called the Natural Resources and Parks Division), in coordination ","th the Surface Water Management Division, to conduct a reconnaissance of 29 major drainage basins located in King County. The effort began with an initial investigation of three basins -Evans, Soos, and Hylebos Creeks -in order to determine existing and potential surface water problems and to recommend action to "mitigate and prevent these problems. These initial investigations used available data and new field obsetvations to examine geology, hydrology, and habitat conditions in each basin. Findings from these three basins led the King County Council to adopt Resolution 6018 in April 1986, calling for reconnaissance to be completed on the remaining 26 basins. The Basin Reconnaissance Program, which was subsequently established, is now an important element of surface .... ."ter management. The goals of Ihe program are to provide useful data "'"th regard to 1) critical problems needing immediate solutions, 2) basin characteristics for use in the preparation of detailed basin management plans, and 3) capital costs associated .... 1th the early reSOlution of drainage problems. The reconnaissance reports are intended to provide an evaluation of present drainage conditions in the County in order to transmit information to policymakers to aid them in developing more detailed regulatory measures and specific capital improvement plans. They are not intended to ascribe in any conclusive manner the causes of drainage or erosion problems; instead, they are to be used as initial surveys from which choices for subsequent detailed engineering and other professional environmental analyses may be made. Due to the limited amount of time available for the field work in each basin, the reports must be viewed as descriptive environmental narratives rather than as final engineering conclusions. Recommendations contained in each report provide a description of potential mitigative measures for each particular basin; these measures might provide maximum environmental protection through capital project construction or development approval conditions. The appropriate extent of such measures will be decided on. a case.by..case basis by County officials responsible for reviewing applications for permit approvals and for choosing among competing projects for public construction. Nothing in the reports is intended to substitute 1 Soos Creek Basin (continued) for a more thorough environmental and engineering analysis posstble on a site-specific basis for any proposal. m. FINDINGS IN SOOS CREEK BASIN P:SCB Reconnaissance in the Soos Creek Basin was conducted in November 1985 by Ray HeUer, resource planner, Randall Parsons, engineer, and Don Spencer and John Bethe~ coD$Ulting soil scientists. Their findings and recommendations are presented as foUO\\"S. A. Overview of Soos Creek Basin Geographic and land use features.. The Soos Creek Basin is located north and east of the Green River in the eastern portion of the Soos Creek Plateau Community Planning Area. The basin is situated east of the city of Kent, northeast of Auburn, and southeast of Renton. The city of Seattle's Lake Youngs "'"lI,tershed is included in the Soos Creek Basin. The south and east portions of the basin are rural in character, ",ith the north and west portions committed to a suburban development pattern that includes subdivisions and scattered single-family homes. The 1985 King Countv Comprehensive Plan shO\\1; areas east of Big Socs Creek (in the northern part of the basin) and south of Lake Youngs with "rural development" designations that specify 1-5 dwelling units (DU) per acre. The southern area to the east of Soos Creek and north of the Green River is designated "transitional." This interim designation will limit development to rural- res,idential densities until such time as, rural/urban designations are made through updated community plans. The King County Parks Department owns more than a five-mile stretch from Southeast 192nd Street to Lake Meridian, along Big Socs Creek. These presently undeveloped park lands are mostly wetlands and lie ",ithin the 100-year floodplain. Major geologic, hydraulic, and hydrologic features. The Socs Creek drainage area is a tributary basin to the Green River basin. The area is part of the Puget ,Spund lowlands and is characterized by a glacial drift plain, covered by small ridges and rounded hills that were formed by continental glaciation. While the Socs Creek Basin is moderately developed, the degree and amount of channel erosion, slope failures, and other forms of geologic and hydraulic damage are far less than might be expected. Artificial conveyances are also still functioning in this basin as they were originally designed and intended. These conditions may be explained by three main factors, First, there is a very effective natural retention and detention (RID) system provided by an n"tensive network of 52 wetlands and numerous major and minor streams. Most of the wetlands are located in the northern portion of the basin in the upland areas as well as adjacent to streams. Big Socs Creek originates in the northeast Comer of the plateau and flows southeast to the junction of Little Soos and Jenkins Creeks, then curves west at its confluence ",;th Covington Creek. Big Soos Creek joins the Green River east of Auburn near State Road (SR) 18 at 160th Avenue SE. These wetlands and streams appear to be functioning well as stormwater control facilities for the current levels of development, as well as serving to prevent damage from surface water runoff. 2 Soos Creek Basin (continued) Second, the soils in the upland areas generally have a high infiltrative capacity, particularly in the southern P'?rtion of the basin. Stormwater is absorbed into the ground at these locations before it can cause erosion or other damage. Third, development i~ the basin has only just begun. Properly functioning wetlands and streams have not yet been altered, nor have well-draining soils been covered by impervious surfaces to any great extent. Maintaining these properly functioning drainage systems should be a goal in this basin and will be the focus of recommendations made later in the report. Habitat chazacteristics. The h¥bitat of Soos Creek Basin is generally good and supports large populations of both native and hatchery anadromous fish. The source of the hatchery fish is a State facility near the mouth of Soos Creek. Cutthroat trout reside in stream waters, and anadromous fish spawn and travel in many of the tributaries and the main stem of Big ~. according to field observations and reports from local residents at the time of reconnaissance. Habitat is being damaged or threatened in some places by bank erosion and degraded v.ater quality associated "'ith land clearing, livestock feces, and wetland filling for development. One of the more serious instances of habitat-threatening erosion originates at the parking lot of the Seattle International Raceway (SIR), which is located on the plateau in the Iov.·er portion of the basin. Drainage from the paved parking lot is increasing erosion in nearby tributaries and filling spawning gravels with sediment. . Appendix C of this report identifies sites of habitat damage or potential damage. Further water quality information related to habitat in the basin can be found in the Critical Stream Inventorv of Soos Creek, published by Metro. R Effects of Urbanization Low levels of development in most parts of the Saos Creek Basin, together "ith a weIl.functioning natural drainage system: have kept serious erosion, sedimentation 1 and habitat damage to a minimum until now. However, the present and projected rates of development indicate that there could be increasing amounts of damage, as suggested by the types of problems observed during reconnaissance. The expansion of impervious surfaces in the basin is already beginning to accelerate the rates and volumes of SlOrmwater flowing into (and reducing the capacities of) both natural and artificial channels. Impervious surfaces are also reducing the amount of highly pervious soils available 10 absorb runofr. The predictable impacts are already. in evidence: erosion, mass-wasting, sedimentation, and degraded water quality and other habitat destruction. The following section provides a mOre detailed account of problems found during field investigation. c. Specific Problems Identified The study team e""mined numerous sites along the main stem of Big Soos, Little Soos, and West Soos Creeks, as well as 21 small drainages tributary to these main stems. Several of the most significant problems found during reconnaissance are '.., described below. P:SCB 3 Soos Creek Basin (continued) L , Bam:: failures. On Tnoutary 0072A, river mile .30, for exam pie, there exists a major bank failure triggered by bank undercutting. The source of the problem appears to be increased runoff from street construction. Unless [(ows are intercepted and redirected to storm sewers or other facilities, there will be increased bank erosion and consequential deterioration of property and stream habitaL 2. Channel Erosion. This includes both instream and bank erosion caused by large volumesqf runoff emerging from storm drains and washing away highly e.rodible soils. This creates a new, deeply incised channel that enlarges over time. One example of this problem occurs on Tnoutary 0072 near the SIR in the lower part of the basin. Large expanses of pavement at this location have contnouted to' high volume [("",os and channel erosion. 3,.' Flooding and potential flooding. In numerous locations, de"l:lopment has increased the amount of runoff entering existing drainage facilities or otherwise impeded the ability of natural systems to carty the amount of runoff. When drainage systems fail to function as they were intended, flooding can occur. Increased development without concurrent increases in drainage facilities adds to the possibility that serious flooding .... ill occur. On Tnoutary 0092, river mile 1.20, for example (collection point.,ll), the Little Soos ,has been contained and manicured as it passes through a de"l:loped piaL Such alteration to a natural drainage channel reduces the stream's capacity in places. The result bas been the regular semi-annual flooding of some homes. Further development could aggravate these kinds of flooding problems. 4. Poor stream habitat due to: a. Lad: of overhead canopy and streamside vegetation. Overhead canopy stabilizes water temperature, while streamside vegetation protects banks from erosion. b. Contamination by livestock feces. In areas of the basin where livestock have e>."lensive access to streams, water quality has become degraded by animal feces. These cause harmful nutrients to be added to the water which can threaten fish survival Co Erosion. Streambank and channel erosion, already describ.ed above, is caused in part by livestock access. On Tributary 0073, river miles 3.60-4.70, for e,,-ample, there e,,;sts poor stream habitat because livestock have trampled and denuded banks of vegetation; this has led to the sedimentation of spawning areas and caused turbidity. IV. RECOMMENDATIONS FOR ACTION The follo .... ing recommendations are based on findings of the field team and reflect the original 'goals of the Basin Reconnaissance Program, as outlined in the introduction of this report. A Inform appropriate governmental agencies of the detailed findings from the reconnaissance of this basin. Project representatives should meet .... ith staff from King Soos Creek Basin (continued) County Roads Division, Surface Water Management Division, Building and Land Development, and other inte.;ested agencies to transmit relevant information. B. RccYaIuate specific policy is<;ue:s reganliDg surface water management. These may include the need to: L Jmprow: enforcement of wetlands regulatioas to maintain these areas in t\ieir na!utal states. This will insure their continued function as surface water quality and quantity controllers, as well as' preserve their habitat value. If regulation proves ineffective, the County should secure easements or consider other means to preserve wetland areas. 2. Require the' establishment of undistutbcd buffetS and setbacks adjacent to natural drainage swales. Variations in stream morphology and geology indicate the need Cor stream corridor guidelines that take these into consideration. Improve enforcement of "no clearing" covenants in these sensitive areas Or seek County easements or actual o\\llership. Fencing along streams in livestock areas v,ould help water quality and reduce erosion and sedimentation. 3. Investigate and promote the infiltration of surface water where feasible and economical to reduce increased runoff from developed areas. Also, encourage the use of grass swales and open ditch conveyance systems to improve infiltration and water quality enhancement capacity. Arc;as of high mtration are identified on final display maps (Cor the Basin Reconnaissance Program) in the offices of Surface Water Management, BUilding and Land Development, and Basin Planning. 4. Require the tigbtlining oC storm-drainage outCalIs down steep or sensitive stopes using state-of·the-art facilities, including high density polyethylene pipe with energy dissipation at the outfall. 5. Reevaluate stormwater rate and volume release regulations for new developments. Current· regulations may be inadequate and result in unacceptable downstream erosion that causes property damage and loss of habitat. 6. Increase current maintenanCe levels for King County surface water RID and conveyance Cacilities. Due to the lack of funding, maintenance of existing facilities is sometimes insufficient and results in Cacility dysfunction and failure. These v.ill only be aggravated by additional upstream development. 5 Soos Creek Basin (continued) c. Prepare a comprehc::osiw: basin plan to consider., at a minimum, the need to: L Enhance: and utilize the. extcosiw: existing 1M:tIands as regional storm-dctcntion facilities without jeopardizing habitat values. Prepare a schedule for the anticipated need for these hydrologic enhancements as they relate to projected development in the basin and impact the wetland ecology. 2. Famine eristiog storm-dctcntion and conveyance facilities to determine whether their control orifices are .properly sized to nptimize the detention site and achieve the maximum benefit to the downstream systems. 3. Establish floodplains in Iow-Jying areas of slight vaalCDt for existing and developed runoff conditions. i.e, adjacent to wetlands, panicularly for wetlands proposed as regional detention sites where inundation of adjacent properties may be Significant. 4. Identify stream reaches critical to the maintenance of anadromous and trout populations. 5. Review geologic rmdings from this study in order to identify areas of particular soils' sensitivity and develop special analysis criteria for new developments. D. Coostruct the capital improvement projects according to the aP priority selection criteria. These projects, identified in Appendix B of this repcirt, include projects to: 1 Calibrate and retrofit existing detention-control structures and to improve existing conveyance systems. 2. Stabilize channels and slopes. 3. Provide regional deteDtion facilities, including the utilization of wetlands, where biological assessment has determined that the natura.l habitat values "ill not be significantly altered. E. Maintain or enhance the instream and riparian habitats. 1. Maintain wetlands and buffer areas around them. These provide both valuable ,,;ldlife habitat and natural stonnwater storage that helps to m~intain year.round basenov.-s in the stream. 2. Adopt a stream-corridor policy in the Soos Creek Community Plan to protect the stream corridor from damaging types of land uses in adjacent areas. 3. Encourage the Washington State Department of FJSheries to allow use of the natural stream system for salmoD spaMung. Maintain a natural run of all the indigenous anadromous species. 4. Prohibit rt!ling in the lOO·year noodplain. The County should establish regulations to prevent the 1055 of noodplains in order to maintain their natural storage [or Ooodwaters and guard against degradation of important fish and wildlife habitat.

APPENDIX B CAPITAL IMPROVEMENT PROJEcr RANKING SOOS CREEK BASIN Prior to the Soos Creek watershed field reconnaissance, 13 projeQ.s had been identified and rated using the CIP selection criteria developed by the Surface Water Management (SWM) Division and the Natural Resources and Paries Division. Following the reconnaissance, 20 projects remain proposed for this area. They include the 7 new, previously unidentiflCd and unrated projects plus the initial 13 projects. The previoWl .. SWM capital improvements project list for the Soos Creek Basin had an estimated cost of S3,450,OOO, while the revised list decreases to an estimated cost of $2,622,000. This 24% reduction in estimated capital costs is due mainly to downward revised cost figures for acquiring or securing easements over wetlands. The follov.;ng table summarizes the scores and costs for tbe CIPs proposed for the Hylebos Creek Basin. The projects were rated according to previously established SWM Program Citizen Advisory Comminee criteria. The projects ranked below are those for which the first rating question, ELEMENT 1: "GO/NO-GO: could be answered affirmatively. The projects can now be considered for merging into the "live" crp list. Any project scoring over 100 points should be considered for incorporation into the Six-year CIP plans. RANK PROJEcr NO.
