Project Description The proposed VIA 405 Apartments project is located within the Renton Village site at 25 South Grady Way in Renton as shown in the Attachment A site vicinity map. The proposed project would include the construction of up to 270 multi-family apartments that would replace an existing 2,320 seat movie theatre. The site has private easement access to public right-of-way as it is located on a portion of the Renton Village site. Primary vehicular access to the site is expected at the intersections of S Grady Way/Lake Ave S, Talbot Road S/S Renton Village Place, and S Grady Way/Shattuck Ave S. The proposed residential project is expected to be completed and occupied by 2020. A preliminary site plan is included in Attachment B. Trip Generation The trip generation estimates for the proposed and existing use were based on methodology documented in the Institute of Transportation Engineers (ITE) Trip Generation Manual, 9th Edition for Apartments (LUC 220) and Movie Theatre with Matinee (LUC 444). Adjustments to the trip generation estimates were made to account for local mode-split data (applied to the proposed residential use only) and to also account for internal trips between the proposed and existing uses and the existing Renton Village shopping center use which is approximately 100,000 square feet adjacent to the proposed VIA 405 Apartments. Local mode-split adjustments were made to the trips associated with the proposed residential land use. The proposed project is located within Census Tract 253.02, where 70.5% of workers commute to work via vehicle with an average vehicle occupancy (AVO) of 1.13 according to the US Census Bureau 2015 American Community Survey. Therefore, an adjustment was made to the residential trip generation to reflect the use of non-vehicle modes of transportation. It should be noted that this local mode-split adjustment may be considered conservative given the fact that the Renton Transit Center is proposed to be relocated across the street from the VIA 405 project on Grady Way S in coordination with the Sound Transit 3 project, and as such, non-vehicle trips may increase as a result of the relocated transit center. Trip Generation Memo VIA 405 Apartments TENW March 7, 2017 Page 2 Internal trips are made by people making multiple stops within a development without generating new trips onto the adjacent street system. The internal trip adjustments between the proposed residential use, existing movie theatre use, and existing adjacent Renton Village shopping center use were based on methodology established in the recently published Institute of Transportation Engineers (ITE) Trip Generation Handbook, 3rd Edition, August 2014. The net new trip generation associated with the proposed VIA 405 Apartments project was calculated by subtracting the trip generation associated with the existing movie theatre. The resulting net weekday daily, AM peak hour, and PM peak hour trip generation estimates are summarized in Table 1. Detailed trip generation calculations are included in Appendix B which includes the mode-split adjustments and internal trip capture calculations. Table 1 VIA 405 Apartments – Net New Trip Generation Summary Net New Trips Generated Time Period In Out Total Weekday Daily -170 -170 -340 Weekday AM Peak Hour 5 59 64 Weekday PM Peak Hour -43 -59 -102 As shown in Table 2, the proposed VIA 405 Apartments project is expected to generate fewer trips on a weekday and during the PM peak hour compared to a 2,320 seat theatre. The net AM peak hour trips are expected to be greater with the proposed VIA 405 Apartments with 64 net trip generation. Transportation Impact Fee Estimate The City of Renton requires payment of transportation impact fees to mitigate traffic impacts of new development. Per the City of Renton 2017/2018 Fee Schedule the current transportation impact fee is $3,358.55 per multi-family dwelling unit and $321.57 per seat for a movie theatre. After applying impact fee credit for the existing 2,320 seat movie theatre, the estimated net transportation impact fee for the proposed 270 unit VIA 405 Apartments would be $160,766.10.
