TO: Andrew Van Gordan, Associate Planner
FROM: Brianne Bannwarth, Development Engineering Director
SUBJECT: Traffic Concurrency Test
WSADA Headquarter Expansion
621 SW Grady Way (APN 3340404730); LUA22-000381
The applicant is requesting administrative site plan review and Environmental (SEPA) Review to
construct a 1,390 square foot expansion to the existing building. The project site is 32,672 square
feet and is located at 621 SW Grady Way. The property is within the Commercial Arterial (CA)
zone, Commercial Mixed Use Land Use Designation and Auto Mall Area A. The site is improved
with an existing office building and associated surface parking. The project includes a request to
reduce the minimum front yard setback (along SW Grady Way) from 15 feet to 12 feet and the
minimum secondary front yard setback (from Raymond Ave SW) from 15 feet to 10 feet. New
landscaping is proposed on-site and within the public right-of-way along Grady SW and Raymond
Ave SW. One significant tree is proposed for removal and replacement. The project also includes
a modification request to maintain existing off-site improvements. The project site is within a
High Seismic Hazard Area.
The proposed development would generate approximately 15 net new average weekday daily
trips. During the weekday AM peak hour, the project would generate approximately 2 net new
trips (2 inbound and 0 outbound). During the weekday PM peak hour, the project would generate
approximately 2 net new trips (0 inbound and 2 outbound). The proposed project passes the City
of Renton Traffic Concurrency Test per RMC 4-6-070.D as follows:

Traffic Concurrency Test Criteria Pass
Implementation of citywide Transportation Plan Yes
Within allowed growth levels Yes
Project subject to transportation mitigation or impact fees Yes
Site specific street improvements to be completed by project Yes
Traffic Concurrency Test Passes
Evaluation of Test Criteria
Implementation of citywide Transportation Plan: The City’s investment in completion of the
forecast traffic improvements is greater than 100% of the scheduled expenditure through 2022.
Within allowed growth levels: The citywide traffic concurrency trip capacity for concurrency with
the city adopted model for 2022 is 2,371 trips. The trip balance provides sufficient capacity to
accommodate approximately 2 trips from this project. A resulting 2,369 trips are remaining.
Project subject to transportation mitigation or impact fees: The project will be subject to
transportation impact fees at time of building permit issuances for the project.
Site specific street improvements to be completed by project: The project will be required to
complete frontage street improvements prior to occupancy. Any additional off-site
improvements identified through SEPA or land use approval will also be completed prior to
occupancy.
Background Information on Traffic Concurrency Test for Renton
The City of Renton Traffic Concurrency requirements for proposed development projects are
covered under Renton Municipal Code (RMC) 4-6-070. The specific concurrency test requirement
is covered in RMC 4-6-070.D, which is listed for reference:
D. CONCURRENCY REVIEW PROCESS:
1. Test Required: A concurrency test shall be conducted by the Department for each
nonexempt development activity. The concurrency test shall determine consistency with
the adopted Citywide Level of Service Index and Concurrency Management System
established in the Transportation Element of the Renton Comprehensive Plan, according
to rules and procedures established by the Department. The Department shall issue an
initial concurrency test result describing the outcome of the concurrency test.

2. Written Finding Required: Prior to approval of any nonexempt development activity
permit application, a written finding of concurrency shall be made by the City as part of
the development permit approval. The finding of concurrency shall be made by the
decision maker with the authority to approve the accompanying development permits
required for a development activity. A written finding of concurrency shall apply only to
the specific land uses, densities, intensities, and development project described in the
application and development permit.
3. Failure of Test: If no reconsideration is requested, or if upon reconsideration a project
fails the concurrency test, the project application shall be denied by the decision maker
with the authority to approve the accompanying development activity permit application.
The Concurrency Management System established in the Transportation Element on page XI -65
of the Comprehensive Plan states the following:
Based upon the test of the citywide Transportation Plan, consideration of growth levels
included in the LOS-tested Transportation Plan, payment of a Transportation Mitigation
Fee, and an application of site-specific mitigation, development will have met City of
Renton concurrency requirements.
