SUBJECT: Transportation Concurrency Test
Sound Transit South Renton Transit Center (SRTC): LUA24-000233
750 Rainier Ave S (1923059035, 1923059063, 1923059068, and
1923059074
The applicant, Sound Transit, is requesting master plan review, site plan review, Hearing
Examiner conditional use permit, lot line adjustment, bicycle parking modification, and driveway
modification to construct the South Renton Transit Center (SRTC) located at 750 Rainier Ave S
(APNs 1923059035, 1923059063, 1923059068, and 1923059074). The subject property is
approximately 8.3 acres and is in the Commercial Mixed Use Comprehensive Plan designation,
Commercial Arterial (CA) zone, and the Urban Design District D overlay district. The site is mostly
flat with impervious surfaces. Initially developed as an auto dealership and service garage, the
businesses that were previously on the site have been relocated.
Sound Transit has partnered with Washington State Department of Transportation (WSDOT) to
implement new bus rapid transit (BRT) service along I-405. As part of the I-405 BRT program,
Sound Transit is proposing to construct BRT facilities in Renton, Burien, Tukwila, Bellevue,
Kirkland, Bothell, and Lynnwood. The transit center would include stops for Sound Transit and
King County Metro (KCM) routes, bus operator facilities, transit shelter canopy, 8 bus bays, 13 -
bus layover spaces with a gantry for bus charging, 158-stall surface parking lot for transit center
users, and bicycle racks/lockers. Vehicle access would be from Rainier Avenue S and Lake Avenue
S.
Environmental review was completed by Sound Transit, as its own lead agency completed
environmental review and issued a State Environmental Policy Act (SEPA) Determination of Non -
Significance on September 30, 2020. In 2021, the applicant received a demolition permit, a critical
areas exemption (for work within a Seismic Hazard Area), and a critical areas approval (for work
within a Wellhead Protection Area) for the demolition and removal of the four buildings that

were onsite. Additional work would include roadway improvements on Rainier Avenue S, Hardie
Avenue SW, S Grady Way, and Lake Avenue S (APN 1923059032) to facilitate bus and pedestrian
ingress and egress to the site, landscaping, utility improvements, and construction of a
stormwater conveyance and treatment system.
The proposed development would generate an increase of approximately 2,436 net new average
weekday daily trips. During the weekday AM peak hour, the project would generate an increase
of approximately 380 net new trips (308 inbound and 75 outbound). During the weekday PM
peak hour, the project would generate an increase of approximately 404 net new trips (92
inbound and 312 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 2024.
Within allowed growth levels: The citywide traffic concurrency trip capacity for concurrency with
the city adopted model for 2024 is 1,944 trips. The trip balance provides sufficient capacity to
accommodate an decrease of approximately 404 trips from this project. A resulting 1,540 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 receiving a certificate of occupancy. Any
additional off-site improvements identified through land use approval will also be completed
prior to receiving 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.
