TO: Alex Morganroth, Senior Planner
FROM: Brianne Bannwarth, Development Engineering Manager
SUBJECT: Traffic Concurrency Test – Watershed Apartments
(615 and 617 Williams Avenue S); LUA21-000239
The applicant is requesting Environmental (SEPA) Review, Preliminary Planned Urban
Development approval, and Final Planned Urban Development approval to construct (6) story,
66.5-foot tall standalone residential building. The subject site is located across four parcels
addressed as 615 and 617 Williams Ave S (APNs 1723059069, 1723059136, 1823059115, and
1823059282. The four (4) parcels total 1.34 acres in area. The three (3) southern -most parcels
are located in the Center Downtown (CD) zoning district and C ommercial Mixed Use (CMU)
Comprehensive Plan Land Use Designation. The northern-most parcel is located in the
Residential-14 (R-14) zone and Residential High Density (RHD) Comprehensive Plan Land Use
Designation. All four (4) parcels are located in the City Center Sign Area overlay and Urban Design
District A overlay districts. The site is developed with an existing multi -family building located at
615 Williams S and a standalone billboard at 617 Williams S. The ground floor of the proposed
building would consist of 57 stalls of structured parking, a lobby, and back of house spaces. The
five (5) floors above would include 145 affordable housing units and various amenity spaces.
Approximately 45 surface parking stalls would be located along the north side of the site. Primary
vehicle access to the site is proposed via a driveway of Williams Ave S, with emergency access
provided via a secondary controlled-access driveway off of S Grady Way. A pedestrian
promenade is proposed along the east side of the site connecting S Grady Way to the Burnett
Linear Park west of the site. Frontage improvements including a sidewalk, planter strip, and curb
and gutter are proposed along S Grady Way and Williams Ave S. The applicant has submitted a
transportation impact analysis, geotechnical report, arborist report, and technical information
report with the application.

The proposed development would generate approximately 710 net new average weekday daily
trips. During the weekday AM peak hour, the project would generate approximately 50 net new
trips (14 inbound and 36 outbound). During the weekday PM peak hour, the project would
generate approximately 62 net new trips (38 inbound and 24 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 1,158 trips, which provides sufficient capacity to
accommodate approximately 62 additional trips from this project. A resulting 1,096 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 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 devel opment 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.
