TO: Clark Close, Principal Planner
FROM: Brianne Bannwarth, Development Engineering Director
SUBJECT: Traffic Concurrency Test
SW Grady Office and Shop Building; LUA23-000300
340 Logan Ave N (APN 1823059264)
The applicant is requesting administrative site plan review, environmental (SEPA) review, and a
street modification to construct a 9,418 square foot one-story office and shop building at 1404
SW Grady Way (APN 2423049061). The subject property is approximately 27,175 square feet
(0.62 acres) and is located within the Medium Industrial (IM) zoning designation. The site is
mostly impervious surfaces and the applicant is proposing to retain the existing 1,520 square foot
building during construction of the new building for material storage. After construction, the
material would be relocated to the new building and the existing building would be demolished.
In addition to the new building, the site work would include a vehicle parking, pedestrian
walkway, landscaping, and other associated utility improvements. Once the site work has been
completed, approximately 85% of the property would be covered with impervious surfaces.
Access to the property is from SW Grady Way.
The site is relatively flat. Grading would include 10 cubic yards of cut and 1,210 cubic yards of fill
from a local gravel pit. The applicant is proposing a street modification to retain the existing curb
and gutter, sidewalk, and landscaping along the project frontage.
The proposed development would generate approximately 75 net new average weekday daily
trips. During the weekday AM peak hour, the project would generate approximately 14 net new
trips (11 inbound and 3 outbound). During the weekday PM peak hour, the project would
generate approximately 17 net new trips (5 inbound and 12 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 greater than 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 2,014 trips. The trip balance provides sufficient capacity to
accommodate approximately 17 trips from this project. A resulting 1,997 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 issuances for the project.
Site specific street improvements to be completed by project: The project will be required to
complete frontage street improvements prior to occupancy unless a modification is approved.
Any additional off-site improvements identified through SEPA or land use approval will also be
completed prior to 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.
