DATE: SIGNATURE OF DIRECTOR OR AUTHORIZED REPRESENTATIVE REV.5/90 devrvsht CITY OF RENTON MEMORANDUM DATE: March 12, 1991 TO: Don Erickson VIA: Dick Anderson FROM: Randall Parsons STAFF CONTACT: David M. Christensen Ron Straka SUBJECT: METRO'S DRAFT SUPPLEMENTAL ENVIRONMENTAL IMPACT STATEMENT (DSEIS) The Storm and Wastewater Utility staff has reviewed Metro's Draft Supplemental Environmental Impact Statement (DSEIS). Our review focuses specifically on storm water and wastewater issues. Our comments are as follows: WASTEWATER UTILITY REVIEW COMMENTS: The DSEIS should be amended to include appropriate mitigation measures to revise Metro's current policy of surcharging to elevation 22, to not allowing the surcharge to exceed two feet below adjacent manhole rim elevations for the interceptors and collector sewers (per our previous memo). Currently the DSEIS only mentions the problem (Pg. 2-7), but does not include specific mitigation measures to correct the potential for raw sewage spills during surcharging. The DSEIS does correctly identify the two projects that directly affect the City (Pg. 2-6). However, prior to approval of the supplemental EIS, an acceptable agreement for commitment to these improvements by Metro shall be entered into by the City of Renton and Metro. If you have any questions regarding the above, please call Dave Christensen at 277-6212. Metro's Draft Supplemental Environmental Impact Statement (DSEIS) Page 2 STORM WATER UTILITY REVIEW COMMENTS: SECTION: SURFACE WATER RESOURCES - Existing Conditions (page 4-17 through 4-22) The existing conditions section needs clarification and the following is provided to supplement existing information: History of the East Side Green River Watershed Plan (P-1 Channel, Black River Pumping Station and Forebay) a) In 1960 the Valley Cities Renton, Kent, and Tukwila, the King County Conservation District, and Drainage District No. 1 passed a resolution agreeing to participate in a jointly sponsored request for Federal assistance for flood control under the Watershed Flood Prevention Act (PL-566) administered by the Soil Conservation Service. b) In 1965 the Soil Conservation Service developed a detailed work plan for the East Side Green River Watershed Plan. This work plan was approved and funded by the U.S. Congress in 1966. c) This lead to the construction of the Black River Pumping Station and channelization improvement of 0.5 miles of the Black River channel from its confluence with the Green River by the local sponsors with assistance from the Soil Conservation Service in 1971. d) In 1982 the local sponsors withdrew from the East Side Green River Watershed Plan. e) In 1984 the City of Renton reactivated its portion of the East Side Green River Watershed Plan and Between 1984 and 1989 the City of Renton with assistance from the Soil Conservation Service constructed the Black River Pumping Station Forebay and approximately 2,500 linear feet of the P-1 Channel from the Black River Pumping Station Forebay to Grady Way. Other improvements included the construction of the Grady Way Box Culvert, The 1-405 box culvert which is currently not operational, and in 1990 the City started construction of the new SW 16th Bridge which is still under construction. All of the construction was accomplished with assistance from the Soil Conservation Service to some degree or another. f) In 1988, the City of Renton conducted an environmental study to determine the adequacy of the 1981 NEPA Environmental Impact Statement for the continuation of the East Side Green River Watershed Plan improvements south of Grady Way. The City along with recommendations from several important resource agencies determined that too many changes had occurred since the original NEPA EIS was development to re-adopt the document. Some of these changes include the regulation and preservation of wetlands, impacts to water quality, the changes in storm water management standards such as on-site detention in the watershed, impacts to fisheries resources, and the availability of continuous simulation hydrologic and hydraulic models. Metro's Draft Supplemental Environmental Impact Statement (DSEIS) Page 3 g) In May of 1990 the City of Renton retained R.W. Beck and Associates and their project team to prepare the supplemental technical and environmental information needed for the preparation of a environmental document which satisfies concerns raised during the determination adequacy study, but still uses the original NEPA EIS as the foundation for the East Side Green River Watershed Plan. Our consultants are currently developing a Hydrological Simulation Program-FORTRAN (HSPF) hydrologic model for the entire East Side Green River Watershed. A hydraulic model is also being developed for the Watershed with the use of the Full Equations Hydraulic Model (FEQ). This phase of work The P-1 channel is the portion of Springbrook Creek between the Black River Pumping Station Forebay to the Grady Way Box culvert which has been re-channeled and improved for flood control purposes. The remainder of 12 miles of channel south of Grady Way is the Existing Springbrook Creek some of which was dredged and re-channeled by King County Drainage District No. 1. in the late 50's to early 60's. The P-1 channel is only approximately 2,500 linear feet long. The East Side Green River Watershed is comprised of the remnants of the.old Black River, the P-1 channel, Springbrook Creek, Panther Creek, Garrison Creek, and Mill Creek. The Watershed contains portions of jurisdictional boundaries of Renton, Kent and Tukwila along with portions of unincorporated King County (see attached map). This drainage system does not convey any drainage from the Southcenter area. SECTION: SURFACE WATER RESOURCES - Existing Conditions (page 4-24): The Panther Creek Wetlands/P-9 Channel project is a mitigation project of the East Side Green River Watershed Plan Environmental Mitigation Agreement as approved by the SCS and the local sponsors in 1980. This agreement compensated for the environmental impacts resulting from the approved work plan developed by the SCS and as adopted in the SCS Final EIS for the East Side Green River Watershed Plan. The DSEIS references the Valley Study Project but does not include a description the project. The Valley Study Project includes our current hydrologic and hydraulic modeling work along with the integration of our other planning efforts into a comprehensive plan for the valley. The SW 16th Bridge improvement increases capacity only because the old bridge pilings are being removed from the channel. The channel (Springbrook Creek) is no being improved to P-1 Channel standards at this time. METRO trunk line surcharging and overflow into the P-1 channel, the Black River, and the Renton Wetland did occur during the January 9, 1990 storm not the January 9, 1991 storm. Surcharging may not have occurred during the November, 1991 (not November 1990) storm. The January 9, 1990 storm had a five day rainfall total from January Sth thru the loth of 7.98 inches which is estimated to occur once every 70 years. The 24 hour rainfall total on January 9th was 3 inches which is estimated to be a 30 year storm event (City of Renton January 9, 1990 Storm Report). Metro's Draft Supplemental Environmental Impact Statement (DSEIS) Page 4 SECTION: SURFACE WATER RESOURCES - Impacts/mitigation (page 5-14 - 5-19) Storm water management for the METRO Treatment Plant expansion must be done in accordance with the City of Renton Storm and Surface Water Drainage Ordinance (City Code chapter 4-22). The City has adopted applicable portions of the King County Surface Water Design Manual (KCSWDM) in the Ordinance. The DSEIS identifies WSDOE Draft Storm Water Manual erosion control measures which are adequate, but there are additional measures that could be employed and are listed in chapter 5 of the KCSWDM. The site may have an adequate outlet to the Green River with the old effluent line, but per our City Code the runoff must be treated prior to direct discharge into the Green River by a combination of biofiltration and wet ponds. The storm water direct discharge will be required by the Department of Ecology to comply with the new National Point Discharge Elimination System (NPDES) permit requirements. The estimation of each proposed alternative runoff quantity should be calculated as specified in the KCSWDM. This review does not constitute the Utility's approval of the projects drainage plan. The City will issue a permits after site plan approval and construction plans have been reviewed and approved. STORM WATER UTILITY REVIEW SUMMARY: The Existing Conditions information contained in the METRO Treatment Plant Enlargement DSEIS needs to be clarified and the sites storm water management shall be done in accordance with the City's Storm and Surface Water Drainage Ordinance.

P-Tmemo-t' January 29, 1991 Joe Fernandes,Manager METRO Plant Expansion 821 Second Ave. MS 107 Seattle,WA.98104-1598 SUBJECT: INFORMATION REGARDING SURCHARGING OF THE METRO SOUTH INTERCEPTOR AND THE CITY OF RENTON SANITARY SEWER SYSTEMS. Dear Mr.Fernandes: The City of Renton submits for your Departments review information regarding observed locations where surcharging of the METRO South Interceptor has occurred and as a consequence resulted in the associated City of Renton sanitary sewer systems to also surcharge. This information has been compiled over the last two years by the City Maintenance Division and Utility Systems Division staff. The highlighted manholes show the systems which have surcharged when the METRO South Interceptor has surcharged including during those periods of intense rainfall. If you have any questions,or need any additional information,please contact Mike Benoit at 277-6206.
