Subject: Concordia Trip Generation Assessment
The intent of this memo serves to provide a trip generation evaluation for the proposed 82,826
square feet manufacturing tenant occupancy within an existing building located at 851 SW 34th
Street in the city of Renton. A site description and project summary are provided below.
Project Description
The subject property, parcel 125381-0270 (6.72-acres), proposes tenant improvements for
approximately 82,826 square feet of an existing 171,710 square foot building. The building has
previously been occupied with similar industrial type uses (e.g., manufacturing, warehouse, etc.).
The proposed tenant would occupy roughly half of the building space, as shown in the site plan on
the following page, for light manufacturing purposes. Site development also includes the
replacement of approximately 13 truck loading docks along the west side of the building for an
additional 19 vehicle parking spaces. Shown below is a site aerial with the adjacent street system
included. No change in driveway access from SW 34th Street is proposed.

Trip Generation
The number of vehicular trips entering/exiting the site have been estimated using data obtained
from the Institute of Transportation Engineer's publication Trip Generation, 10th Edition.
Consistent with the project description, the applicable Land Use Codes (LUC) in the trip
generation manual is defined as and LUC 140 – Manufacturing. ITE rates have been applied using
“square feet” as the independent input variable. Estimations include average weekday daily trips
(AWDT) and the AM and PM peak hour volumes. Table 1 below summarizes the project trip
generation.

Land Use LUC Sq. Ft. AWDT AM Peak-Hour Trips PM Peak-Hour Trips
In Out Total In Out Total
Manufacturing 140 82,826 326 39 12 51 17 38 55
In total, the tenant can be estimated to generate 326 average weekday daily trips with 51 trips
occurring in the AM peak hour and 55 in the PM peak hour. Truck trips are estimated to comprise
five percent of the AM and PM peak hour volumes (2 & 3 trips, respectively) based on ITE data.
Manufacturing uses generally have a portion of the building space allocated towards office/admin
use. Therefore, the entire building space was applied for calculations under LUC 140.

Conclusion
A tenant improvement and new occupancy is proposed for 82,826 square feet of an existing
171,710 square foot industrial building within the city of Renton limits. The subject property is
situated on the south side of SW 34th Street and just east of Oakesdale Avenue SW. The tenant
would be light manufacturing, similar to former uses ranging from warehouse distribution to light
manufacturing. Based on ITE data, the project is estimated to generate 326 daily trips, 51 AM
peak hour and 55 PM peak hour trips. As part of site development, approximately 13 truck loading
docks would be eliminated and replaced with 19 vehicle parking spaces, inferring a reduction in
truck traffic to and from the site. No change in driveway access is proposed.
