SUBJECT: Traffic Concurrency Test – Funbox
(IPN 1923059043)
LUA26-000146
The applicant is requesting Environmental (SEPA) Review for a change of use and interior
tenant improvement project to convert an existing retail space, estimated at 20,000 square
feet, into an indoor recreational facility. All proposed improvements would be interior to the
tenant space, no exterior site improvements are proposed. The project site is located at 601
S Grady Way (APN 1923059043), a 9.80-acre parcel within the Renton Village Shopping
Center Complex (totaling 426,966 square feet). This site is zoned Commercial Arterial (CA)
and is situated within Urban Design District D and the Rainier Grady Junction Overlay. The
comprehensive land use designation is Commercial Mixed Use and the Community
Planning Area is City Center. It features public street frontage on S Grady Way and S Renton
Village Place, with no proposed modifications to existing access. City of Renton mapping
identifies the site within high seismic hazard areas, containing a piped segment of Rolling
Hills Creek, within special flood hazard areas (FEMA Zone – AH), and part of the Downtown
Wellhead Protection Area Zone 2. Tree removal is not anticipated. The applicant submitted
a SEPA Environmental Checklist with the application.
The proposed development would generate no new net daily trips. During the weekday AM
peak hour, the project would generate a decrease of approximately 43 weekday AM peak
hour (29 in, 14 out). During the weekday PM peak hour, the project would generate no net
new trips. 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 2026.
Within allowed growth levels: The citywide traffic concurrency trip capacity for concurrency
with the city adopted model for 2026 is 2,259 trips, which provides sufficient capacity to
accommodate no new trips from this project. A resulting 2,259 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 for the project.
Site specific street improvements to be completed by project: The project will be required
to complete street frontage improvements prior to issuance of a certificate of occupancy.
Any additional off-site improvements identified through land use approval will also be
completed prior to issuance of a certificate of 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.
