TO: Andrew Van Gordon, Associate Planner
FROM: Brianne Bannwarth, Development Engineering Manager
SUBJECT: Traffic Concurrency Test – Castro Short Plat
(12727 SE Petrovitsky Rd - APN 0739000085); LUA22-000053
Three lot short plat. The applicant is requesting approval of a Preliminary Short Plat. Lot sizes
range from 9,009 square feet (Lot 2) to 10,722 square feet (Lot 1). Two tracts are proposed. Tract
A (6,148 sq. ft.) is for the purpose of tree preservation, and Tract B (1,770 sq. ft.) is for the purpose
of emergency vehicle access. Associated site improvements include access improvements,
landscaping and stormwater infrastructure. The subject property is 1.13 acres (49,389 square
feet) and is located in the Residential Low Density Comprehensive Plan land use designation and
the Residential - 4 (R-4) zoning classification. Vehicle access would be provided via a new public
street extending from SE 176th St; emergency vehicle access (Tract B) would extend from 1 20th
Ave SE.
The proposed development would generate approximately 28 net new average weekday daily
trips. During the weekday AM peak hour, the project would generate approximately 2 net new
trips (1 inbound and 1 outbound). During the weekday PM peak hour, the project would generate
approximately 3 net new trips (2 inbound and 1 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 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 960 trips, which provides sufficient capacity to accommodate
approximately 3 additional trip from this project. A resulting 957 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 appr oval 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.
