FROM: Brianne Bannwarth, Development Engineering Manager
SUBJECT: Traffic Concurrency Test – 38th Street Short Plat
(18809 116th Ave SE); LUA22-000022
The applicant is reapplying for approval of a Preliminary Short Plat of the former 38th Street Short
Plat (previous file number LUA18-000683) that has expired. The applicant is requesting
Preliminary Short Plat approval, a street modification, and an addendum to the existing
Environmental (SEPA) Review for the subdivision of an existing 62,781 square foot project site
zoned R-8, into 8 lots and 2 tracts (shared driveway/alley and native growth protection area). An
existing single-family residence is proposed for removal. The proposed lots would range in size
from 5,000 square feet to 6,522 square feet. Access to the proposed lots would be provided via
a shared driveway/alley off of NE 38th Street. Half street improvements, including paving, curb
and gutter, landscaping with street trees, and sidewalk would be provided along the site's Lincoln
Ave NE and NE 38th Street frontages. The site is mapped with erosion hazard areas, landslide
hazard areas, sensitive slopes, and protected slopes. A Modification to the City's adopted street
standards has been requested for the portion of N 38th Street to the west of the proposed private
access driveway. The applicant is requesting to waive the frontage improvements along the steep
slopes and to limit the frontage improvements to a sidewalk, parking area, and landscaped
courtyard over the proposed stormwater vault.
The proposed development would generate approximately 66 net new average weekday daily
trips. During the weekday AM peak hour, the project would generate approximately 5 net new
trips (1 inbound and 4 outbound). During the weekday PM peak hour, the project would generate
approximately 7 net new trips (4 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 955 trips, which provides sufficient capacity to accommodate
approximately 7 additional trips from this project. A resulting 948 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 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.
