A geotechnical report dated October 21, 2021, completed by Robinson-Noble, was provided with the Land Use Application. The report discusses the soil and groundwater characteristics of the site and provides recommendations for project design and construction. Geotechnical recommendations presented in this report support the use of permeable pavement as the only viable infiltration style BMP due shallow groundwater observed approximately 2 feet below ground surface. 2. Daley-Morrow-Poblete Inc., with the Land Use Application, submitted a Preliminary Drainage Plan and Technical Information Report (TIR), dated March 13, 2023. Based on the City of Renton’s flow control map, the site falls within the Flow Control Duration Standard- Matching Forested and is within the Soos Creek Drainage Basin. The report is based on a Full drainage review and Core Requirements 1 thru 9 and the six Special Requirements have been discussed in the Technical Information Report. a. Offsite Analysis, RSWDM Core Requirement #2: All proposed projects must submit an offsite analysis report that assesses potential offsite drainage and water quality impacts associated with development of the project site. The preliminary TIR submittal includes a Level 1 Downstream Analysis that does not identify any downstream drainage problems. b. Flow Control, RSWDM Core Requirement #3: Any proposed detention and/or water quality vault shall be designed in accordance with the RSWDM that is current at the time of civil construction permit application. The project proposes to use an R-tank for the detention facility which is conceptually acceptable. c.

Financial Guarantees and Liability, Core Requirement #7: All persons constructing any surface water facilities (including flow control/water quality, conveyance systems, erosion control and road drainage) are to post with the City a surety device. The amount of the surety is calculated using the City’s bond quantity worksheet. The preliminary TIR indicates that this will be provided if required. i. A Bond Quantity Worksheet shall be submit as part of the civil construction permit. g. Water Quality, RSWDM Core Requirement #8: All projects that add more than 5,000 square feet of pollution generating impervious surface (PGIS) that is not fully dispersed and less than 0.75 acre of pollution generating pervious surface that is not fully dispersed require water quality. The TIR indicates that the project is adding less than 5,000 SF of PGIS and is exempt. i. The project exceeds the 5,000 SF threshold, however, if a leechable metals covenant is provided for the individual lot rooftops, then the rooftops will not be counted as PGIS and the project would be exempt. The TIR submit with the civil construction permit shall include a draft copy of the covenant. h. Onsite BMPs, RSWDM Core Requirement #9: Appropriate on-site BMPs will be required to help mitigate the new runoff created by this development. The proposal discusses the feasibility of each BMP as listed in section 1.2.9.2.1 Small Lot BMP requirements. i. Each BMP feasibility shall be explicitly assessed with specific infeasibility criteria cited where not feasible. 2. A construction Storm Water General Permit from the Department of Ecology will be required as clearing and grading of the site is shown to exceed one acre. 3.
