MEMORANDUM
DATE: May 27, 2026
TO: City of Renton
FROM: Curtis Chin, P.E.
TENW
SUBJECT: Trip Generation Memo
WareSpace Tenant Improvement at 700 Powell Ave SW (Renton, WA)
TENW Project No. 2026-128
This memorandum documents the trip generation estimate for the WareSpace Tenant Improvement (TI)
to occupy the existing building located at 700 Powell Ave SW in Renton, WA.
Project Description
The proposed tenant improvement project includes converting 96,543 SF of former manufacturing space
into an 88,464 SF WareSpace facility in the existing building located at 700 Powell Ave SW. A WareSpace
concept converts/subdivides large underused industrial buildings into smaller warehouse bays for
entrepreneurs and growing businesses. The Renton WareSpace facility would include 79,467 SF of
warehouse space and 8,997 SF of office space. As part of the proposed TI project 8,079 SF of existing
mezzanine space would be removed. A preliminary site plan is included in Attachment A. A summary of
the building land uses is shown in Table 1. It should be noted that based on information provided by the
applicant at other similar WareSpace facilities, it is anticipated that on a typical weekday only 35 to 40
percent of the building would be actively used.

Trip Generation
The trip generation estimates for the proposed and former uses for the WareSpace TI project were based
on methodology documented in the Institute of Transportation Engineers (ITE) Trip Generation Manual,
12th Edition for Land Use Code (LUC) 150 (Warehousing), LUC 712 (Small Office), and LUC 140
(Manufacturing).
The resulting net new weekday daily, AM peak hour, and PM peak hour trip generation estimates for the
proposed project are summarized in Table 1. The detailed trip generation estimates are included in
Attachment B.

As shown in Table 1, the proposed WareSpace TI project is estimated to generate fewer trips than the
prior manufacturing use.
Next Steps
Per the City of Renton’s Policy Guidelines for Traffic Impact Analysis for New Development, a traffic impact
analysis (TIA) is required when estimated vehicular traffic generated from a proposed development
exceeds 20 vehicles per hour in either the AM (6:00 ‐ 9:00) or PM (3:00–6:00) peak periods. Since the
proposed WareSpace TI project is estimated to generate less than 20 net new weekday AM or PM peak
hour trips, a TIA would not be required for the project.
