SUBJECT: Traffic Concurrency Test – Haevin Ridge Short Plat
(18809 116th Ave SE); LUA21-000468
The applicant is requesting preliminary short plat approval and a street modification for the
subdivision of an existing 57,934 square foot (1.32 acre) site into six (6) residential lots and three
(3) tracts. The project site is located at 18809 116th Ave SE (Parcel #3223059075) between SE
186th St and SE 192nd St. The project site has a zoning designation of Residential -8 du/ac (R-8).
Two existing cell towers are located on the west side of the property and a 300 square foot
telecoms building is located along the north property line. Both the towers and the telecoms
building would remain. The proposed lots range in size from 5,000 square feet to 5,850 square
feet with a net density of 5.39 du/ac. Access to Lots 1 through 5 is proposed via a 35 -foot (35’)
wide half-street along the south side of the site, while Lot 6 would take access via a driveway off
of 116th Ave SE. Access to the cell tower and telecoms building proposed for retention would be
provided via a utility easement on the school property to the north of the subject site and existing
utility easements on the western portion of the site would be relinquished. The applicant has
proposed a stormwater vault in a 7,567 square foot tract on the north side of the site. No critical
areas are mapped on or within 200 feet of the project site. A similarly short plat on the subject
site was approved under LUA18-000205 on June 7, 2018. The preliminary approval expired on
December 7, 2021 prior to recording of the final short plat and therefore the applicant has
reapplied for preliminary approval. Substantial progress has been made on the construction of
the utilities and frontage improvements, which will continue during review of the new
preliminary application.
The proposed development would generate approximately 57 net new average weekday daily
trips. During the weekday AM peak hour, the project would generate approximately 4 net new
trips (1 inbound and 3 outbound). During the weekday PM peak hour, the project would generate

approximately 6 net new trips (3 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 is 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 908 trips, which provides sufficient capacity to accommodate
approximately 3 additional trips from this project. A resulting 902 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 final short plat recording. Any additional off-site
improvements identified through SEPA or land use approval will also be completed prior to final
short plat recording.
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.
