The following comments are based on the Land-Use submittal made to the City of Renton by the applicant. EXISTING CONDITIONS WATER: The project is within the King County Water District 90 service area. SEWER: The project is within the City of Renton’s sanitary sewer service area. There is an 8-inch gravity wastewater main located in 156th Ave SE (see record drawing S-399902). The existing structure is connected to an on-site septic system. STORM: There are existing public stormwater ditches and culverts on the east side of 156th Ave SE. STREETS: The proposed development fronts 156th Ave SE on the western property line. 156th Ave SE is classified as a minor arterial street with an existing right of way width of 60-feet. Water 1. Applicant shall obtain a water availability certificate from the District and provide it with the civil construction permit submittal. i. A water availability certificate from Water District 90 was provided with the Land Use Submittal. 2. Review of the water plans will be conducted by King County Water District 90 and the Renton Regional Fire Authority. 3. Plans approved by King County Water District 90 shall be routed to the City for final review prior to permit issuance. Sanitary Sewer 1. A minimum 8-inch sewer main extension will be required to extend from the existing 8-inch main in 156th Ave SE to the northern most extents of the property. Sewer main extensions shall be in accordance with RMC 4-6-060. i. The sewer main location as shown is conceptually acceptable. 2. Individual sewer stubs from the new sewer main and individual side sewers are required for each lot. All new sewer stubs shall conform to the standards in RMC 4-6-040 and City of Renton Standard Details. i.

Payment of these fees is required at time of building permit issuance. Surface Water 1. A geotechnical report dated December 20, 2022, completed by Innovative Geo-Services, LLC, was provided with the Land Use Application. Geotechnical recommendations presented in this report support the use of infiltration at a rate of 4 in/hr. 2. A preliminary TIR dated July 5, 2024 was submitted by Tebaldi Engineering with the Land Use Application. The site falls within the Flow Control Duration Standard Matching Forested Site Conditions and falls within a flood problem flow control standard thus the report shall also meet the requirements of the Flood Problem Flow Control Standard. The site falls within the Lower Cedar River drainage basin. The report is based on a full drainage review and Core Requirements 1 through 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. 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 preliminary TIR claims an exemption from a flow control facility requirement as the target surfaces generate less than 0.15 cfs increase in the existing site conditions 100 years peak flow. Therefore, the project meets the basic exemption from Core Requirement #3 in the 2022 RSWDM section 1.2.3. i. Per the preliminary TIR, infiltration trenches will be utilized to fully infiltrate lot run-off, thus, reduce the total run-off of the site to less than 0.15 CFS. Per the geotechnical report, the underlying soil is silty, gravelly sand while full infiltration is only feasible under coarse sand, cobbles, and medium sand soil conditions. Additional infiltration calculation per section 5.2 of the 2022 RSWDM is required at the time of civil construction permit. c. Conveyance, RSWDM Core Requirement #4: All new conveyance systems constructed as part of the project must be sized to RSWDM standards for the total tributary area (onsite and offsite) that the storm systems serve. The proposal indicates that an analysis will be provided with final engineering. i. A conveyance system and capacity analysis shall be provided with the TIR and submit at time of civil construction permit application. d. Construction Stormwater Pollution Prevention, Core Requirement #5 ii. A CSWPP shall be provided with the TIR and submit at the time of civil construction permit application. e. Maintenance and Operations, Core Requirement #6 iii. A maintenance and operation manual shall be provided with the TIR and submit at the time of civil construction permit application. f. 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 all PGIS surfaces will be treated with a Contech Storm filter. i. A water quality analysis and system sizing shall be provided in the TIR and submit at time of civil construction permit application. g. 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 indicates that BMP feasibilities will be evaluated with final engineering. i. A discussion of the feasibility of BMPs in section 1.2.9.2.1 Small Lot BMP requirements shall be provided at the time of civil construction permit application. 3. Erosion control measures to meet the City requirements shall be provided. i. Erosion control plans shall be submit at the time of civil construction permit application. 4. The development falls within the R-4 zone which has a maximum impervious surface area of 50% per lot, and maximum building coverage of 35% per lot. 5. 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. • The current SDC fee for a single family residence is $2,350 per lot. • The current property contains one single family home, the developer will receive a credit for the existing home if it is demoed. • The full fee schedule can be found at: https://edocs.rentonwa.gov/Documents/DocView.aspx?id=10067864&dbid=1&repo=Cityof Renton Transportation 1.
