Infiltration tests and geotechnical report meeting all the requirements of the 2017 City of Renton Surface Water Design Manual (RSWDM) should be provided with the construction permit. The infiltration testing should be performed at a minimum at the location where infiltration on-site BMPs are proposed for the project. The location of the infiltration test currently included in the report is near NE 2nd Street and the full infiltration BMP is proposed in Tract A access tract, located further away from the infiltration test location. 2. A Preliminary Drainage Plan and Technical Information Report (TIR), dated March 20, 2019 and revised on October 22, 2020, was prepared by Litchfield Engineering with the Land Use Application. Based on the City of Renton’s flow control map, the site falls within the Flow Control Standards Forested site conditions and is within the Lower Cedar Drainage Basin. The development is subject to Directed Drainage Review in accordance with the 2017 Renton Surface Water Design Manual (RSWDM). The site is located in the Flow Control Standard Forested Site Conditions. All nine core requirements and the six special requirements have been discussed in the Technical Information Report. A private combined detention/wet vault is proposed to meet the detention and water quality requirements of the project. The location of the proposed stormwater vault is within the tract located inside the project as shown in the plans. The stormwater tract is proposed to gain access directly from NE 2nd Street by means of a driveway. The detention/water quality vault shall be designed in accordance with the RSWDM. All new conveyance systems constructed as part of the project must be sized to RSWDM standards for the total tributary area that the storm systems serve. A drainage plan and Technical Information Report (TIR) per RSWDM should be provided with the construction permit. Analysis should be included to show that the downstream facilities have the capacity to meet the drainage from the site and the upstream tributary area. 3. Appropriate on-site BMPs will be required to help mitigate the new runoff created by this development. A preliminary drainage plan, including the application of on-site BMPs, has been included with the land use application. The final drainage plan and TIR shall be prepared in accordance with RSWDM and must be submitted with the civil construction permit application. a. Final evaluation of the application of on-site BMPs to the maximum extent feasible will be completed during civil construction permit review. Additional infiltration tests are required to be done on the site where infiltration BMPS are proposed. If the infiltration tests do not provide information that the required minimum infiltration rate is available at the proposed full infiltration BMP location, the applicant may be required to apply additional on-site BMPs in order to meet the minimum requirements outlined in Core Requirement #9. This may impact the maximum ground impervious surface allowed on the lots, which may impact the building square footage. 4. Separate building permit is required for the stormwater vault. 5. A Construction Stormwater General Permit from Department of Ecology will be required for projects that have clearing and grading exceeding one acre. 6. Surface water system development fee is applicable to the project. The current rate of this fee is $2,000 per new single-family residence. This is payable prior to issuance of the construction permit. The rate that is current at the time of construction permit issuance will be applicable on the project.
