FROM: Nathan Janders, Development Engineering Manager
SUBJECT: Traffic Concurrency Test – Sophie Jo Short Plat
(APN 7222000110); LUA24-000081
The applicant is requesting Preliminary Short Plat approval for the subdivision of an existing
22,085 square foot (0.507 acres) located within the Residential -8 (R-8) zone into three lots and
one utility and access tract (Tract A). The proposed lots would have the following areas: Lot 1
would be 5,850 square feet, Lot 2 would be 6,040 square feet, and Lot 3 would be 5,939 square
feet. Access to Lot 1 is proposed via a residential driveway off of Smithers Ave S and access to
Lots 2 and 3 is proposed via a shared driveway (Tract A) off of S 21st St. A moderate coal mine
hazard area is mapped on the project site.
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 2024.
Within allowed growth levels: The citywide traffic concurrency trip capacity for concurrency with
the city adopted model for 2024 is 1,953 trips, which provides sufficient capacity to
accommodate approximately 3 additional trips from this project. A resulting 1,950 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.
