SUBJECT: Traffic Concurrency Test
Lindbergh HS Modernization and Additions
(16426 128th Ave SE); LUA22-000106
The applicant, the Renton School District, is requesting Hearing Examiner Site Plan Review and a
street Modification for various site and building improvements at the Lindbergh High School
campus. Improvements proposed include a 1,630 square foot addition near the existing main
entrance, a 3,030 square foot addition near the northeast corner, renovation of existing
classrooms, and the repair and resurfacing of the existing 73,650 square foot parking on the
southwest portion of the site. The existing building is approximately 229,000 sq. ft. in size and is
located across three (3) parcels totaling approximately 37.25 acres. The site is located at 16426
128th Ave SE (APN # 2823059004, 2823059042, 2823059093) and is zoned Residential-6 (R-6)
du/ac with a Comprehensive Plan Land Use Designation of Residential Medium Density (MD).
Other work proposed on the site includes HVAC system upgrades, reloc ation of underground
utilities near the main entrance, a full upgrade to the gymnasium (interior only), and frontage
improvements along 128th Ave NE. According to COR Maps, a high seismic hazard area and
wetlands are mapped on the site. According to the applicant, one tree would be removed as part
of the project. The project would result in more 5,000 square feet of new or replaced impervious
surface. The applicant submitted a Wetlands Report, Drainage Report, Transportation Impact
Analysis, and Tree Assessment with the application. The Renton School District, acting as the
SEPA lead, issued a Mitigated Determination of Non-Significance with one mitigation measure on
February 23, 2022.
The proposed development would generate no net new daily, AM peak hour, PM peak hour 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 Not Applicable
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 are greater than 100% of the scheduled expenditure through 2022.
Within allowed growth levels: The citywide traffic concurrency trip capacity for concurrency with
the city adopted model for 2022 is 955 trips, which provides sufficient capacity to accommodate
approximately 0 trips from this project. A resulting 955 trips are remaining.
Project subject to transportation mitigation or impact fees: The project currently is not proposing
any net new person vehicle trips; therefore, transportation mitigation or impact fees are not
required unless required through SEPA review and approval.
Site specific street improvements to be completed by project: The project will be required to
complete frontage street improvements prior to occupancy. 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.
