FROM: Brianne Bannwarth, Development Engineering Manager
SUBJECT: Traffic Concurrency Test
Maple Highlands Preliminary Plat
13929 154th Ave SE; LUA22-000122
The applicant is requesting Preliminary subdivision approval for a 12-lot plat. Lot sizes range from
9,034 square feet (Lot 6) to 11,256 square feet (Lot 1). One tract is proposed for the purpose of
stormwater facilities (21,846 square feet). Associated site improvements include access
improvements, landscaping and stormwater infrastructure. The project area is two lots (13929 -
154th Ave SE & 13818 - 152nd Ave SE) totaling 4.16 acres (181,167 square feet) and is located in
the Residential Low Density Comprehensive Plan land use designation and the Residential - 4 (R4)
zoning classification. Vehicle access would be provided via two new public streets: 1) an
extension of SE 139th Pl between 152nd Ave SE and 154th Ave SE, and 2) 153rd Ave SE with a
hammerhead easement turnaround between Lot 6 and Lot 7.
The proposed development would generate approximately 94 net new average weekday daily
trips. During the weekday AM peak hour, the project would generate approximately 7 net new
trips (2 inbound and 5 outbound). During the weekday PM peak hour, the project would generate
approximately 10 net new trips (7 inbound and 3 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 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 961 trips, which provides sufficient capacity to accommodate
approximately 10 trips from this project. A resulting 951 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 final plat approval. 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.
