This memorandum has been prepared to respond to comments received from the City of Renton in a letter dated March 21, 2022 that state a traffic impact analysis is required and a subsequent discussion with the City that indicated they would reconsider the traffic impact analysis requirement depending on the anticipated net trip generation impact of the proposed project. We are requesting your review and approval of this information and confirmation of that no additional traffic analysis is required for the Home Depot Renton project. Project Description The Home Depot Renton project is located at 901 South 7th Street and would consist of a 137,983 SF home improvement store. The existing site is currently vacant but was previously occupied by a 136,918 SF discount club (SamÊs Club) and a gas station with 12 vehicle fueling positions (VFPs). Buildout and occupancy of the Home Depot project is expected in 2022. A site plan is included in Attachment A. Trip Generation The trip generation estimates for the proposed and existing uses were based on methodology documented in the Institute of Transportation Engineers (ITE) Trip Generation Manual, 11th Edition for Land Use Code (LUC) 862 (Home Improvement Superstore), LUC 857 (Discount Club), and LUC 944 (Gasoline/Service Station). Adjustments to the trip generation estimates were made to account for pass-by trips. Pass-by trips are trips that are made by vehicles that are already on the adjacent streets and make intermediate stops at commercial uses on route to a primary destination (i.e., on the way from work to home). Pass-by trips were based on studies included in the appendices of the ITE Trip Generation Manual, 11th Edition, 2021. The net new trips associated with the Home Depot Renton project were determined by estimating the total trips from the proposed project and then subtracting out the trips generated by the existing use. Per direction from the City, the trips associated with the existing Discount Club and Gasoline/Service Station (to be removed) were reduced by 50 percent since the SamÊs Club and gas station have been vacant for more than Trip Generation Memo Home Depot Renton TENW April 3, 2022 Page 2 3 years. The resulting net new weekday daily, AM and PM peak hour trip generation for the proposed project is summarized in Table 1. The detailed trip generation estimate is included in Attachment B. Table 1 Project Trip Generation Summary Net New Trips Generated Time Period In Out Total Weekday Daily 48 49 97 Weekday AM Peak Hour 23 20 43 Weekday PM Peak Hour -23 -19 -42 As shown in Table 1, the proposed Home Depot project is estimated to generate 97 net new weekday daily trips with 43 net new trips occurring during the weekday AM peak hour (23 in, 20 out) and a decrease of 42 net new trips occurring during the weekday PM peak hour (-23 in, -19 out). Next Steps Upon your review of this information, we would like to confirm that no additional traffic analysis will be required for the proposed Home Depot Renton project.
