Trip Generation and Transportation Impact Fee Estimate
TENW Project No. 5399
This memorandum documents the trip generation and transportation impact fee estimate for the proposed VIA
405 Apartments project located in Renton, Washington.
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 (see Attachment Q. 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.
