TO: Valerie Porter, Senior Planner
FROM: Nathan Janders, Development Engineering Manager
SUBJECT: Traffic Concurrency Test – Al-Mahdi Society of Washington
(APN 1253600050)
LUA25-000270
The applicant is requesting an Environmental (SEPA) Review and Hearing Examiner Condition Use
Permit to allow for four existing commercial suites to be used for social services, which is located
at 200 SW 41st St (APN: 125360-0050). The existing two-story commercial building sits on a lot
approximately 35,000 square foot (0.80 acres) in size and is within the Commercial Arterial (CA)
zoning district and Employment Area (EA) land use designation. Primary vehicular access to the
site will continue to be gained from a drive aisle off SW 41st St. The proposal will not include
structural changes or modification to the building exterior. No trees are proposed for removal.
According to City of Renton (COR) Maps, the site is not impacted by critical areas. The applicant
submitted a Traffic memorandum justification letter with the application in association with the
Environmental (SEPA) Review.
The proposed development would generate an increase of approximately 167 weekday daily
trips. During the weekday AM peak hour, the project would generate an increase of 11 weekday
AM peak hour (7 in, 4 out). During the weekday PM peak hour, the project would generate an
increase of approximately 15 net new trips (7 in, 8 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 N/A

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 2,160 trips, which provides sufficient capacity to
accommodate approximately 15 additional trips from this project. A resulting 2,145 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 is exempt from street
frontage improvements. 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.
