Docusign Envelope ID: B29EB968-C739-45B8-8E1F-7522EE3C1A3A ADVISORY NOTES TO APPLICANT Page 3 of 5 LUA24-000218 The site is in the Soos Creek drainage basin. Since most of the site falls within Zone 2 of the Aquifer Protection Area (APA), stormwater open conveyance systems, such as ditches and channels, and water quality facilities may require a liner per section 6.2.4 and 1.2.4.3 of the 2022 RSWDM. a. A preliminary Technical Information Report prepared by Encompass Engineering & Surveying dated January 28, 2025, was submitted by the Applicant with the Land Use Application, which was prepared following the 2022 Renton Surface Water Design Manual (RSWDM). b. The drainage assessment indicates that a full drainage review is required. Staff concurs with the assessment. c. Core Requirement #2, off-site analysis: A downstream analysis was performed by Encompass Engineering & Surveying. The stormwater runoff from the project site discharges to the conveyance system along SE 196th Street, and evaluation stopped 1/4 mile downstream at Glenridge Elementary School. There were no drainage complaints or issues within a quarter mile of the project site. Staff concurs with the assessment. d. Core Requirement #3, per the TIR, an underground system of CMP 90” in diameter detention tank is proposed to meet flow control requirements. The TIR indicates the proposed mitigation will meet the predeveloped conditions of forested conditions, as evaluated using the Western Washington Hydrology Model (WWHM) per the standards of 2022 RSWDM. The preliminary analysis is acceptable and will be further reviewed as a portion of civil construction permit review. 2. Conveyance, Core Requirement #4: All new conveyance systems constructed as part of the project must be sized to 2022 RSWDM standards for the total tributary area (onsite and offsite) that the storm systems serve. a. The preliminary TIR depicts the conveyance system analysis will be provided with the final design. The outlet pipe from the detention facility shall be sized to have the conveyance capacity of 100-year peak flow of post-developed basin. The conveyance evaluation shall be provided and will be reviewed as a portion of civil construction permit application. b. Any connection to the existing stormwater conveyance system along SE 192nd must be approved by the City of Kent. A confirmation letter or approval from City of Kent is required as a portion of civil construction permit review. 3. Construction Stormwater Pollution Prevention, Core Requirement #5: The preliminary civil plan and drainage assessment include an ESC and CSWPP plan. a. A final CSWPP and ESC plan shall be included within the TIR and Civil Construction Plans submitted as a portion of the civil construction permit application. 4. Water Quality, RSWDM Core Requirement #8: If the new plus replaced pollution generating impervious (PGIS) surface exceeds 5,000 SF, the applicant will be required to provide enhanced basic water quality treatment. a. The preliminary TIR indicates water quality treatment is required since the project will add more than 5,000 SF of pollution generating surface. The project proposes a Contech Storm Filter catch basin downstream of the detention tank to meet the water quality treatment requirement. Staff has reviewed the analysis and determined it is conceptually acceptable. 5. Appropriate on-site BMPs satisfying Core Requirement #9 will be required to help mitigate the new runoff created by this development to the maximum extend feasible. On-site BMPs shall be evaluated as described in Section C.1.3 of the 2022 RSWDM. A preliminary drainage plan, including the application of on-site BMPs, shall be included with the land use application, as appliable to the project. The final drainage plan and drainage report must be submitted with the utility construction permit. a. The preliminary TIR depicts that infiltration is not feasible due to the presence of fill and groundwater seepage per the Geotechnical Report prepared by Earth Solutions NW dated February 21, 2024. Runoff from the roof areas will be routed directly to the detention facility. The preliminary on-site BMPs feasibility analysis is acceptable and will be further reviewed during the civil construction permit application. Please include soil amendment BMP for disturbed areas that are not covered by impervious surface for civil construction permit. Docusign Envelope ID: B29EB968-C739-45B8-8E1F-7522EE3C1A3A ADVISORY NOTES TO APPLICANT Page 4 of 5 LUA24-000218 6. A geotechnical report for the site is required and shall be submitted with the land use application. Information concerning the soils, geology, drainage patterns, vegetation present, water table and soil permeability, with recommendations of appropriate on-site BMP options with typical designs for the site from the geotechnical engineer, shall be submitted with the application. The geotechnical report should include an on-site infiltration test to clearly show if the site is suitable or unsuitable for infiltration. a. A geotechnical report prepared by Earth Solutions NW dated February 21, 2024, was submitted by the Applicant with the Land Use Application. b. The geotechnical report indicates the subsurface soils are primarily loose silty sand without gravel (Fill). Infiltration is not feasible due to the relatively impermeable native soils. Perched groundwater was observed at all test pits. 7. The development is subject to a surface water system development charge (SDC) fees. Fees will be charged based on the rate at the time of construction permit issuance. a. The current SDC fee for a single-family residence is $2,350 per lot. b.
