FROM: Brianne Bannwarth, Development Engineering Director
SUBJECT: Traffic Concurrency Test – Hardie Townhomes
317 Hardie Ave NW (APN 3185600054); LUA23-000019
The applicant is requesting a Preliminary Short Plat and Site Plan Review for the unit lot
subdivision of an existing 4,992 sq. ft. (0.115 acre) lot located within the Residential Multi-Family
(RM-F) zone. The proposed subdivision would result in the creat ion of two 1,028 sq. ft. unit lots,
an 804 sq. ft. access tract (Tract A), a 1,001 sq. ft. common area (Tract B), and 1,133 sq. ft.
recreation area (Tract C). A 2-unit townhome (duplex) is proposed to be constructed on the
proposed unit lots each unit would have an area of 1,944 sq. ft. (resulting is a total building area
of 3,888 sq. ft.) with a height of 3 stories and 32 feet. Access to the units is proposed via a joint -
use driveway off of Hardie Ave NW. A High Landslide Hazard Area is mapped on the project site.
The proposed development would generate approximately 14 net new average weekday daily
trips. During the weekday AM peak hour, the project would generate approximately 1 net new
trips (1 inbound and 0 outbound). During the weekday PM peak hour, the project would generate
approximately 1 net new trips (0 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 2023.

Within allowed growth levels: The citywide traffic concurrency trip capacity for concurrency with
the city adopted model for 2023 is 1,993 trips, which provides sufficient capacity to
accommodate approximately 1 additional trip from this project. A resulting 1,992 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 inspection of the building permit. Any
additional off-site improvements identified through land use approval will also be completed
prior to final inspection of the building permit.
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.
