FROM: Brianne Bannwarth, Development Engineering Manager
SUBJECT: Traffic Concurrency Test – Renton Elementary School #16
(1058 Chelan Avenue NE); LUA21-000167
The Renton School District is requesting Hearing Examiner Site Plan Review, Conditional Use
Permit, and two modifications for a new elementary school located at 1058 Chelan Ave NE. The
project site includes 11 parcels approximately 11.08 acres with street frontage along both Chelan
Ave NE and Duvall Ave NE. The zoning designation for 10 of the 11 parcels is Residential-8 with
one Residential-10 parcel located on the northwestern portion of the project site. The proposed
elementary school building would be approximately 77,000 square feet and two stories. In
addition to the building, there would be an outdoor classroom area, multipurpose playfield,
hard/soft play areas, and a covered play area. A surface lot would provide parking for 82 vehicles
and a school bus load/unload area would provide capacity for eight full size busses and two
special education buses. Passenger vehicle access to the subject property is proposed at the
south end of the site with one full access driveway along the Duvall Ave NE frontage and one exit
only access on Chelan Ave NE. School bus access would be provided via two driveways along
Duvall Ave NE. The applicant would construct street frontage improvements along both the
Duvall Ave NE and Chelan Ave NE frontages.
The proposed development would generate approximately 1,500 net new average weekday daily
trips. During the weekday AM peak hour, the project would generate approximately 537 net new
trips (295 inbound and 242 outbound). During the weekday PM peak hour, the project would
generate approximately 105 net new trips (47 inbound and 58 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 130% of the scheduled expenditure through 2020.
Within allowed growth levels: The citywide traffic concurrency trip capacity for concurrency with
the city adopted model for 2021 is 1,292 trips, which provides sufficient capacity to
accommodate approximately 105 additional trips from this project. A resulting 1,187 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 frontage street improvements prior to Certificate of Occupancy. Any additional off-site
improvements identified through SEPA or land use approval will also be completed prior to
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
Transportation Concurrency Test – Renton Elementary School #16

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.
