MEMORANDUM

SUBJECT: Traffic Scoping Memo for DCT Industrial at Monster Rd
PRE17-000418
TENW Project No. 5585
This memorandum summarizes the preliminary traffic information for the proposed DCT Industrial Monster
Road project located at 601 Monster Road SW in Renton, WA for the purpose of establishing a scope of
work for the traffic study. This memo includes a project description, project trip generation estimate,
preliminary project trip distribution, and trip assignment estimates. We are requesting your approval of this
information and confirmation that a traffic impact analysis will not be required for this project.
Project Description
The proposed project is located at 601 Monster Road SW in Renton, WA as shown in the Attachment A
vicinity map. The proposed project would consist of up to 166,000 square foot (SF) of building area for
light industrial use. The existing site includes a 143,862 SF light industrial building that would be removed
with the proposed project.
Vehicular access to the site would be provided via three full-access driveways on Monster Road SW and
also via a full-access driveway on the shared access road on the western edge of the project site. A
preliminary site plan is included in Attachment B.
Trip Generation
The trip generation estimate for the proposed DCT Industrial Monster Road project was based on methodology
documented in the Institute of Transportation Engineers (ITE) Trip Generation Manual 10th edition for LUC 110
(Light Industrial). The net new trip generation was calculated by subtracting the trips from the light industrial
building to be removed from the trips generated by the proposed DCT Monster Road project. 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. Detailed trip generation calculations are included in Attachment C.

As shown in Table 1, the proposed DCT Industrial Monster Road light industrial building is estimated to
generate 84 net new weekday daily trips with 7 net new trips occurring during the weekday AM peak hour
(6 in, 1 out) and 5 net new trips occurring during the weekday PM peak hour (1 in, 4 out).
Next Steps
The proposed DCT Monster Road project would generate less than 20 net new trips during the weekday AM
and PM peak hours. Therefore, based on the CityÊs guidelines, no additional traffic analysis is required for
this development. We look forward to your approval of our trip generation estimates and consensus that no
additional traffic analysis is necessary.
