TO: Alex Morganroth, Senior Planner
FROM: Brianne Bannwarth, Development Engineering Manager
SUBJECT: Traffic Concurrency Test – Rogolo Townhomes
(82 Williams Avenue S); LUA20-000180
The applicant is requesting Administrative Site Plan Review, Environmental (SEPA) Review, a
Shoreline Substantial Development Permit, and a Modification in order to construct an 11,000
sq. ft., three-story structure with six (6) townhome-style units and structured parking. The subject
site is located at 82 Williams Ave S (APN 0007200147) and is in the Center Downtown (CD) zone
and Urban Design District A overlay. The site is 6,000 sq. ft. (0.14 acres) in size. An existing single-
family home is proposed for removal. The ground floor of the proposed structure would consist
of vehicle parking, storage, and mechanical equipment. The two floors above would include six
(6), two-bedroom townhome-style units and would yield a net density of approximately 42 du/ac.
Access to the site would be via a single driveway off of Williams Ave S. Critical areas mapped on
the site include a High Seismic Area, Wellhead Protection Area Zone 1 and the Cedar River Reach
B Regulated Shoreline - High Intensity area. No trees are proposed for removal as a result of the
project. The applicant submitted a Drainage Report, Geotechnical Report, and Shoreline Impacts
Memo with the application.
The proposed development would generate approximately 33 net new average weekday daily
trips. During the weekday AM peak hour, the project would generate approximately 2 net new
trips (0 inbound and 2 outbound). During the weekday PM peak hour, the project would generate
approximately 3 net new trips (2 inbound and 1 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 2020 is 1,364 trips, which provides sufficient capacity to
accommodate approximately 3 additional trips from this project. A resulting 1,361 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 any necessary 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.
