Sincerely, Andrew Van Gordon Associate Planner cc: Badanvir Billing / Owner(s) DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: July 23rd, 2024 TO: Andrew Van Gordon, Senior Planner FROM: Huy Huynh, Civil Engineer II SUBJECT: Billing Short Plat 14103 160th Ave SE LUA24-000190 I have reviewed the above-referenced proposal located at parcel(s) 1423059011. The following comments are based on the Land-Use submittal made to the City of Renton by the applicant. The following comments represent additional information or corrections that are required to be made: 1. A preliminary TIR dated August 23, 2022 was submitted with the Land Use Application. Based on the City of Renton’s flow control map, the site falls within the Flow Control Duration Standard- Matching Forested and falls within a Flood Problem Flow Control Standard and is within the Lower Cedar River Drainage Basin. Therefore, the project must match the Existing site conditions for the 100-year peaks, in addition to matching the Forested site conditions for the 2-year and 10- year peaks and the discharge durations from 50% of the 2-year peak to the full 50-year peak. 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. 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 flow control facility as the new/replaced impervious areas for road asphalt paving, driveway drop and sidewalk totaled 3,992 SF. Therefore, the project meets the basic exemption from Core Requirement #3, as less than 5,000 SF of new plus replaced impervious are proposed, and less than 3/4 areas of new pervious surface will be added. i. Staff does not concur with the exemption based on the conceptual plan included with the land use application. The new/replaced impervious surface area of 3,992 SF does not consider impervious surfaces from new roof areas and driveways. Based on preliminary take-off, the added impervious surface exceeds 5000sf. Applicant to revise report b. Water Quality, RSWDM Core Requirement #8: All projects that add more than 5,000 square feet of pollution generating impervious surface 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 states that this project will have under 5,000 sf of new plus replaced PGIS, therefore not requiring water quality. i. Staff does not concur with the cited exemption based on the conceptual plan included with the land use application. Based on preliminary estimate, the fire turnaround creates over 5000 sqft of pollution generating impervious surface area. Therefore, water quality is not exempt, and the applicant will be required to provide basic water quality treatment. The following comments represent additional information or corrections that should be made when considering surface water layout and configuration: 1. 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 a detention facility to meet the flow control requirement. a. In the current configuration, the grading associated with the detention facility may conflict with the critical root zone of saved tree(s) to the east in Lot 3. b. The vault placement is close to the southern property border at significant depth. Applicant should show or provide narrative pertaining to planned construction method; any offsite work will require an executed temporary construction easement prior to construction permit issuance. 1 Andrew Van Gordon From:Corey Thomas <cthomas@rentonrfa.org> Sent:Monday, July 8, 2024 1:51 PM To:Andrew Van Gordon Cc:Huy Huynh Subject:LUA24-000190, Billings Short Plat Comments Attachments:billingssp.docx; billingssp2.docx Andrew, I have concerns about this proposal proceeding. They have not addressed the standard access roadway or turnaround requirements of 20 feet minimum width on the private roadway and the turnaround. They are showing a 16-foot roadway and a 16 foot wide hammerhead turnaround. Also, we stated originally that one new fire hydrant would be required, and they have shown no new hydrants. There are some other new fire hydrants in this area, however, none of them are within the 300-foot requirement. There is an existing fire hydrant on the northern property line. There are two issues with this fire hydrant. It is on a dead end 6 inch water main that will not flow the minimum 1,000 gpm requirement and more importantly, it is not on a standard usable fire access roadway. We will not approve construction documents if this is presented as it is now. I have updated the memo above and included the original memo with the same requirements they have not addressed. Up you to your department if you want this proposal to proceed. Thanks.

M E M O R A N D U M DATE: February 4, 2022 TO: Andrew Van Gordon, Senior Planner FROM: Corey Thomas, Lead Plans Review Inspector SUBJECT: Billings Short Plat 1. The fire flow requirement for a single-family home is 1,000 gpm minimum for dwellings up to 3,600 square feet (including garage and basements). If the dwelling exceeds 3,600 square feet, a minimum of 1,500 gpm fire flow would be required. A minimum of one fire hydrant is required within 300-feet of the proposed buildings and two hydrants if the fire flow goes up to 1,500 gpm. Water in this area of the city is supplied by King County Water District 90. A water availability certificate shall be required from them. It appears from our records that only a 4- inch water main is available in this area, this will not be able to supply the minimum fire flow for the proposed project. Water main extensions and a minimum of one new fire hydrant will be required. Confirm our findings with the water district for exact existing conditions and construction requirements to meet the minimum requirements. 2. The fire impact fees are currently applicable at the rate of $829.77 per single family unit. This fee is paid at building permit issuance. Credit will be granted for the removal of the one existing home. 3. Fire department apparatus access roadways are required to be a minimum of 20-feet wide fully paved, with 25-feet inside and 45-feet outside turning radius. Fire access roadways shall be constructed to support a 30-ton vehicle with 75-psi point loading. Access is required within 150-feet of all points on the buildings. Dead end streets that exceed 150-feet in length require an approved turnaround. A hammerhead type turnaround would meet minimum requirements. See attached specification sheet.
