TO: Brittany Gillia, Assistant Planner
FROM: Brianne Bannwarth, Development Engineering Manager
SUBJECT: Traffic Concurrency Test – Aberdeen Ave 2-Lot Short Plat
(2732 Aberdeen Ave NE); LUA21-000383
The applicant is requesting approval of a Preliminary Short Plat for the proposed subdivision of
an existing 16,951 square foot (0.39 acre) lot into two lots. The subject property is located at
2732 Aberdeen Ave NE (Parcel number 3343901400) and is located within the Residential-8 (R-
8) zone and Residential Medium Density (MD) land use designation. The proposed residential
density is 5.1 dwelling units per net acre. One single family residence and one detached accessory
structure are presently on the subject property. The existing home is proposed to be retained
and the patio on the existing home as well as the detached accessory structure are proposed for
removal. The proposed residential lot sizes are 7,762 SF for Lot A and 7,547 SF for Lot B. Access
to the new lots is proposed via a public alley that extends from Aberdeen Ave NE. The proposal
includes 13 feet of public right of way dedication along NE 28th St and frontage improvements
for NE 28th St and Aberdeen Ave NE. There are currently three (3) significant on-site trees on the
project site, of which the applicant is proposing to retain two (2). Wellhead Protection Area (Zone
2, Wellfield 5A) and Moderate Landslide Hazards are mapped on the subject site. The applicant
submitted an Arborist Report and Geotechnical Engineering Report with the project application.
The proposed development would generate approximately 9 net new average weekday daily
trips. During the weekday AM peak hour, the project would generate approximately 1 net new
trip (0 inbound and 1 outbound). During the weekday PM peak hour, the project would generate
approximately 1 net new trip (1 inbound and 0 outbound). The proposed project passes the City
of Renton Traffic Concurrency Test per RMC 4-6-070.D as follows:

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 over 100% of the scheduled expenditure through 2021.
Within allowed growth levels: The citywide traffic concurrency trip capacity for concurrency with
the city adopted model for 2021 is 1,054 trips, which provides sufficient capacity to
accommodate approximately 1 additional trip from this project. A resulting 1,053 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 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.
