TO: Alex Morganroth, Principal Senior Planner
FROM: Nathan Janders, Development Engineering Manager
SUBJECT: Traffic Concurrency Test – Walker Subaru Expansion
(APN 3340404265)
LUA25-000171
The applicant is requesting an Administrative Conditional Use Permit, Administrative Site Plan
Review, Environmental (SEPA) Review, and street Modification to construct a 14,417 sq. ft.
addition service shop addition and 1,216 sq. ft. drive through addition to the existing service area
on the subject property located at 519 SW 12th St (APN 3340404265). The property is located in
the Commercial Arterial (CA) zoning district and Auto Mall Area A overlay district and has a
Comprehensive Plan Land Use Designation of Commercial Mixed Use (CMU). The proposed
addition would add new service bay stalls, parts storage area, and office space. Approximately
twenty (20) new parking stalls would be established on the site. Access to the site would remain
via the two (2) existing driveways off of Seneca Ave SW and one driveway off of SW 12th St. The
applicant has proposed the removal of five (5) trees. According to City of Renton (COR) Maps, the
site is located within a High Seismic Hazard Area.
The proposed development would generate an increase of approximately 413 weekday daily
trips. During the weekday AM peak hour, the project would generate an increase of 27 weekday
AM peak hour (20 in, 7 out). During the weekday PM peak hour, the project would generate an
increase of approximately 27 net new trips (10 in, 17 out). 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 100% of the scheduled expenditure through 2025.
Within allowed growth levels: The citywide traffic concurrency trip capacity for concurrency with
the city adopted model for 2025 is 2,230 trips, which provides sufficient capacity to
accommodate approximately 27 additional trips from this project. A resulting 2,203 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 for the project.
Site specific street improvements to be completed by project: The project will be required to
complete frontage street improvements prior to issuance of a certificate of occupancy. Any
additional off-site improvements identified through land use approval will also be completed
prior to issuance of a certificate of 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.
