TO: Angelea Weihs, Associate Planner
FROM: Brianne Bannwarth, Development Engineering Manager
SUBJECT: Traffic Concurrency Test – VEK on Aberdeen
(957 Aberdeen Ave NE); LUA19-000280
The applicant is requesting Preliminary Plat, Unit Lot Subdivision, Hearing Examiner Site Plan
Review, Environmental (SEPA) Review, a Street Modification, and a Unit Lot Drive Modification
for 12 townhomes. The subject site consists of one parcel (Parcel n umber 3119900066) located
at 957 Aberdeen Ave NE. The subject site is 54,057 square feet (1.24 acres) and is located in the
Residential Multi-Family (RMF) zoning district and the Residential High Density (HD) land use
designation. The site currently contains one single family residence and several accessory
structures, all of which are proposed for removal in order to construct two new townhome
buildings, both with six units each. The applicant proposes to increase the maximum wall plate
height up to 42 feet and increase the number of stories to four stories for both townhome
structures though the Site Plan Review process. The proposed project would result in a net
density of 20.36 du/ac. The Unit Lot Subdivision is proposed to be subdivided into 12 lots, f our
landscape/common open space tracts, one unit lot drive tract, and one critical area tract. One of
the 12 Unit Lot Subdivision lots would front on and face Aberdeen Ave NE and 11 units would
face common open space. Access to all 12 units is proposed via a new unit lot drive extending
from Aberdeen Ave NE. The applicant is requesting a Unit Lot Drive Modification in order to
increase the number of units that access from the proposed unit lot drive to 12 units, rather than
the maximum of 9 units permitted by code. The applicant is requesting a street modification in
order to match the established standard street section for Aberdeen Ave NE, which allows for a
pavement width of 36 feet, a 5-foot sidewalk, and 0.5-foot curb. No right-of-way dedication is
proposed for this alternative street section.

The proposed development would generate approximately 55 net new average weekday daily
trips. During the weekday AM peak hour, the project would generate approximately 3 net new
trips (1 inbound and 2 outbound). During the weekday PM peak hour, the project would generate
approximately 4 net new trips (2 inbound and 2 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 130% of the scheduled expenditure through 2020.
Within allowed growth levels: The citywide traffic concurrency trip capacity for concurrency with
the city adopted model for 2021 is 1,322 trips, which provides sufficient capacity to
accommodate approximately 4 additional trips from this project. A resulting 1,318 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 applicant has submitted a
street modification that will be reviewed as part of the land use application. The project will be
required to complete frontage street improvements prior to Certificate of Occupancy. Any
additional off-site improvements identified through SEPA or land use approval will also be
completed prior to Certificate of 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.
