TO: Alex Morganroth, Senior Planner
FROM: Brianne Bannwarth, Development Engineering Manager
SUBJECT: Traffic Concurrency Test – Boeing Apron E (737 Logan Avenue N);
LUA19-000145
The applicant, The Boeing Company, is requesting Environmental (SEPA) Review, Hearing
Examiner Site Plan Review, and a variance in order to convert an existing parking lot (S1 Lot) into
an aircraft production area. The subject property (APN 0723059001) is to the east of the Cedar
River along Lake Washington. The site is home to the Boeing 737 plant and associated support
buildings and is located in the Urban Center (UC) zone. The proposal includes three (3) new
outdoor production stalls for aircraft and a new 72,145 sq. ft. (footprint) paint hangar with two
bays. The existing fire station west of the proposed building would be retained. A sound wall and
landscape screening is proposed along the Logan Ave N and N 6th St right-of-way. A parking lot
with approximately 45 stalls would be constructed south of the proposed new building. All work
would occur further than 200 feet from the Cedar River OHWM. Site access is proposed via a
connection between the existing Apron D area to the west and the proposed work area. The
applicant is requesting a variance in order to seek relief from the parking lot landscaping
requirements in RMC 4-4-070. The project would result in new and replaced impervious surfaces,
tree removal, and vegetation removal. The applicant submitted a Drainage Report, Geotechnical
Report, Traffic Impact Analysis, Noise Study, Light Impingement Study, and Parking Analysis with
the application.
The proposed 72,145 square foot manufacturing building has the potential to generate
approximately 284 net new average weekday daily trips per the Institute of Transportation
Engineers Trip Generation Manual 10th Edition. During the weekday AM peak hour, the project
would generate approximately 45 net new trips (34 inbound and 11 outbound). During the
weekday PM peak hour, the project would generate approximately 48 net new trips (15 inbound
and 33 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 1,709 trips, which provides sufficient capacity to
accommodate approximately 48 additional trips from this project. A resulting 1,661 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.
