SUBJECT: Traffic Concurrency Test – Tsai Short Plat
(APN 0345700180); LUA24-000171
The applicant is requesting preliminary short plat and street modification approval to subdivide
a property into two (2) residential lots. The project site is located at 2223 - NE 23rd St (APN
0345700180) and totals approximately 10,556 square feet (0.24 acre) in area. It is zoned
Residential-8 (R-8). Lot 1 is proposed to be 5,151 square feet with Lot 2 being 5,406 square feet.
Proposed access to Lot 1 is via NE 23rd St; proposed access to Lot 2 is via NE 22nd St. The existing
detached dwelling is proposed to be retained on Lot 1.

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 2024.
Within allowed growth levels: The citywide traffic concurrency trip capacity for concurrency with
the city adopted model for 2024 is 1,943 trips, which provides sufficient capacity to

accommodate approximately 1 additional trips from this project. A resulting 1,942 trips are
remaining.
Project subject to transportation mitigation or impact fees: The project will be subject to
transportation impact fees at time of building permits for the project.
Site specific street improvements to be completed by project: The project will be required to
complete frontage street improvements prior to final short plat recording. Any additional off-site
improvements identified through land use approval will also be completed prior to final short
plat recording.
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.
