#5: Project Narrative
The Seattle Sounders FC are pleased at the prospect of bringing their world class
Performance Center to Longacres Office Park (LOP) in Renton. The Sounders FC Center at
Longacres will house all soccer training, team development and office operations for Seattle
Sounders FC, including all youth programs and camps as well as the entire professional
development pyramid from MLS Next Academy through the First Team. Major League Soccer
and other competition games will continue to be held at Lumen Field. For the first time, the
Sounders FC Center at Longacres will enable the Sounders FC to house all business operations
under the same roof, for the winningest franchise since entry into MLS in 2009.
As described in more detail below, the proposal involves re-use of a portion of an existing
office building for Sounders FC office space and indoor training facilities and associated activities,
outdoor recreation facilities including 4 to 5 full-size soccer fields a Goal Keepers Field and
accessory structures, and reconfiguration of existing parking to better accommodate the Sounders
FC programming and facilities. The following project narrative addresses Item #5 elements of the
City’s CUP criteria.
a. Project name, size and location of site:
The project name is the Sounders FC Center at Longacres. The project location is
proposed for the Longacres Office Park (LOP) in Renton, Washington. Within the LOP, the
Sounders “Site” comprises lots 11, 12, 13, 14, and Tract Bof that certain Boeing Longacres
Property Second Amended Binding Site Plan, recorded at King County Recording No.
20050504000673, City of Renton, King County, WA, (the “BSP”),1 plus a portion of office
building 25-20 located on lot 22 of the BSP, and use of shared parking facilities on lot 21. The
address of existing building 25-20 is 1901 Oakesdale Avenue SW. The Sounders Site will include
approximately 50,000 sf within office building 25-20, and some exterior accessory spaces,
including a proposed new accessory viewing deck on the west side of the second floor of the
building. Secure players’ parking is proposed on Lot 21 located at the south side of building 25-20,
with an entrance at the southwest corner of the building.
The Site overall is approximately 30 acres, although the Sounders will use only a portion
of Office Building 25-20 and its shared parking. The Site is bordered to the west by Tract A and
southwest by Pond B and Lot 8 of the BSP. The Site is bordered to the east by Oakesdale Avenue
SW. Access to the Site is from Oakesdale. Office building 25-20 is approximately 288,044 NSF
(311,982 GSF), and the Sounders will lease approximately 50,000 sf indoors on floors 1 and 2. A
new accessory viewing deck proposed to overlook Field 1 from floor 2 will be approximately
1,650 sf in size.
1 A portion of the southwestern playing field clips Lot 8 and has a very small incursion into Tract A. The applicant
proposes to complete a lot boundary adjustment, extending Tract B into Lot 8 and Tract A to avoid the inclusion of
the entirety of Lot 8 and Tract A with this proposal. To avoid permit processing confusion, the submitted materials
presume that the lot boundary adjustment is complete.

Some existing surface parking will be removed for the placement of Field 1 and 2 and additional
parking will be removed to create a secure 1st team parking area in the existing southern parking
field. The total remaining parking area will have approximately 766 surface parking stalls. A
maintenance building (approximately 4,000 sf) and future field restroom (approximately 800 sf)
are proposed to be co-located between fields 2 and 4. See the Site Plan for a calculation of building
coverage per lot, setbacks, etc. Field placement within the Site perimeter is subject to change,
which may also affect the specific location of the maintenance and restroom facilities.
b. Zoning designation of the site and adjacent properties:
The Site is zoned Commercial Office (CO). Adjacent properties within the LOP share the
same CO zoning designation. The Comprehensive Plan land use designation for the Site is
Employment Area (“EA”).
Recreational facilities, outdoor, are allowed in the CO zone by conditional use permit.
Office use, and recreational facilities, indoor, new, are permitted uses in the CO zone.
Indoor recreational uses are limited to 25% of the building gsf. The Sounders’ indoor recreational
use will not exceed 25% of the gsf of building 25-20.
c. Current use of the site and any existing improvements.
The Site includes an existing 5-story, 284,044 NSF (311,982 GSF) office building
(building 25-20) at Longacres Office Park. n In December 17, 2021,Boeing terminated its leases
and moved its commercial airplane services employees to other locations. Building 25-20 is
previously permitted for office use, and housed Boeing employees engaged in commercial airplane
design and operations. The Site includes several undeveloped parcels to the west and south of
building 25-20 and its surface parking lot.
d. Special site features (i.e. wetlands, water bodies, steep slopes.)
The Site includes the following features: high seismic hazard areas, wetlands, special flood
hazard areas.
Seismic. In addition to the playing fields, the only proposed structures are an accessory
viewing deck off of existing Building 25-20 and accessory maintenance building and field-related
restroom. A Geo Engineers geotechnical analysis dated March 23, 2022 is included with this
application.
Wetlands. The Site borders Tract A of the BSP, where Wetland A is located. A Critical
Areas Existing Conditions Letter Report, by Talasaea Consultants, Inc., dated April 29, 2022 is
submitted to with this application. The Letter Report concludes that Wetland A is the only
immediately abutting regulated wetland, with buffers that extend onto the Site. A Wetlands
Mitigation Report, also prepared by Talasaea is submitted with this CUP application package. The
Site also borders Tract A of the BSP, which includes Pond B, a stormwater detention and water
quality pond. Additional water quality treatment appropriate

for the new use and development will be incorporated into the stormwater management system for
the proposal.
Special Flood Hazard Area. A CPL Drainage Report and a Talasaea Biological Assessment
are submitted under separate cover with this application.
No other critical areas are located on the Site
e. Statement addressing soil type and drainage conditions.
Subsurface soils are anticipated to consist of surficial fill from past grading activities
overlying recent alluvial deposits. The fill generally consists of very soft to stiff silt and loose to
medium dense sand with varying amounts of silt and gravel and ranged up to approximately 6 feet
thick. The alluvial deposits generally consist of loose to medium dense sands and gravels with
varying amounts of silt and very soft to medium stiff silt. The sand and silty deposits are generally
interbedded with lenses of soft to medium stiff organic silt. The alluvial deposits in the vicinity of
the site range up to approximately 45 feet deep.
The ground water levels in the vicinity of the site will fluctuate as a function of season,
precipitation and water levels in the Green River. Based on review of the available subsurface
information, the regional groundwater table in the project vicinity varies seasonally at the site and
is near the ground surface elevation during extended periods of wet weather.
A CPL drainage plan and infiltration test is submitted under separate cover with this
application.
f. Proposed use of the property and scope of the proposed development (i.e., height,
square footage, lot coverage, parking, access, etc.):
The description of the Proposal below is broken into the following subparts: (i) Field
Program - Components; (ii) Field Program - Uses; and (iii) Performance Center - Office Building
Components and Uses, (iv) parking.
(i) Field Program--Components
Seattle Sounders FC will construct four to five full-size fields and a Goal Keeper’s Field
(“GK Field”) in 1-2 construction phases over the next five years. This will include two (2)
international-standard full-size natural grass fields (Fields 1 and 2), with Field 1 located directly
abutting the building 25-20 and the GK Field (also a grass field) fitted between Field 1 and Wetland
A. Field 2 is located south of Field 1. International field sizes are 116 yds x 75 yds. The other two
(2) to three (3) full size fields will be artificial turf surface, with at least one FIFA rated turf field
to support competition activities (e.g. match the surface at Lumen Field). The artificial surface
fields will be located to the southern edge of the campus.
The perimeter of the five fields will be fenced for ball control with privacy windscreen that
will extend to protect the privacy of the activities taking place within the field complex. The
perimeter fence will be approximately 10’ high. In addition, the exterior fence line, as well as
fences internal to the fields, will be equipped to further assist with ball control (e.g. 15’ high fixed-
position netting) behind goals and on critical edges to prevent balls from leaving the field complex.

Within the field complex, light poles will be erected, containing directional LED lights
designed specifically to light fields after dark but directed solely at the fields and preventing light
pollution outside of the field complex. Each field may also have its own bench area, moveable
bench shields, trash receptacles (which will be managed by Sounders FC) and designated areas for
water or athletic training activities. Please see the Lighting Plan prepared by Henderson Engineers,
dated April 27, 2022, submitted under separate cover.
Within the field complex in the southern half, a maintenance out-building will be erected,
and will include a permitted wash-out-area for equipment. The out-building will house field
maintenance equipment (e.g. mowers, aerators, hoses, rollers, etc.) and will be erected on a
concrete foundation and slab-on-grade structure. An equipment washdown pad will be provided
with water quality vault for oil containment and water treatment consistent with Storm Drainage
requirements.
Construction access to the field areas will be from the east. Some lot area extending beyond
the field perimeters may be disturbed during construction; any disturbed areas outside the field
complex will be revegetated according to an approved plan. Paved access to the maintenance out-
building will come from the east.
(ii) Field Program—Uses
Seattle Sounders FC will utilize all five fields for all of its soccer training and soccer
business activities. Primarily this use will include regular training activities seven days per week
between mid-January and November. First Team and Second Team professional training sessions
are typically conducted between 10:00 am and 1:00 pm daily on-field, although duration and
specific time of use of the fields will vary. It is intended that some sessions will be open to the
public for viewing as part of Sounders FC’s commitment to remain open to fans and future public
benefits. Similar to current practice at Starfire Sports in Tukwila, WA, the proposal would include
attendance by up to approximately 100 fans when training sessions are open to the public and
advertised as such. When events are open to the public, they will generally be limited in size to up
to approximately 100 attendees. Public events will typically be held on weekends, which will
minimize impacts to weekday traffic and parking on the Longacres campus. These expectations
also apply to the MLS Academy league matches and special events discussed below. Summer
youth camps would likely operate weekdays, but for limited duration, and only about 10 weeks
per year. These events are identified in greater detail in the TENW Trip Generation Memo dated
June 27, 2022, submitted with this application under separate cover.
MLS Next Academy training activities typically are conducted between 4:00 pm and 8:30
pm Monday-Thursday. In addition, Seattle Sounders FC would host all of its MLS Next Academy
league matches on site, typically 1-2 weekends per month September-November and January-
April, and other friendly competition. MLS Next match spectator attendance would be typical of
a highly attended elite youth competition (approximately 50-100 spectators), and are not paid
tickets—while a professional youth training development program the program remains amateur.
This may also include hosting US Youth National Team identification opportunities or hosting
matches for local youth club partners of Sounders FC. Spectators may be seated in moveable
bleachers (similar to Starfire Sports or school district sites).

Seattle Sounders FC youth programs (like camps) typically operate during school year
breaks (e.g. spring break and summer break) and are operated between 9:00 am and 4:00 pm during
those windows (~10 weeks per year). Youth programs may also operate as after school weekly
clinics or classes (4:00-8:00 pm). Youth programs are operated both as a pay-to-participate, and
for free, throughout the year.
Sounders FC fields may also host partner soccer activities (e.g. naming rights partner
employee day at Sounders FC) and/or private events, including but not limited to special events
like RAVE Foundation fundraisers or charity matches.
(iii) Performance Center – Building Program and Use
Seattle Sounders FC will occupy approximately fifty thousand (50,000) square feet on the
first and second floors of the building located at 1901 Oakesdale Avenue SW, located primarily
on the west side of the building but running from the SW to the NW corner thereof. The portion
of the building on the first floor will adjoin Field 1, the First Team natural grass training field, and
will include a patio between the building and the training pitch to be used as a transition zone,
player lounge and VIP area.
Directly above the first-floor patio, Seattle Sounders FC will construct an accessory
viewing deck, which shall be accessible from staircases at ground level and/or by exiting the
building on the second floor within Sounders FC’s office suite. The deck will create a covered area
for the first-floor patio and be utilized by Sounders FC staff and guests and private Sounders FC
events, as well as serve as a public viewing deck for training sessions, when they are made
available to the public. Additional outdoor elements include the player outdoor training area and a
small lap pool.
The interior of the first floor will include the soccer operations suite and shall be inclusive
of all player, player medical (which may include a health care clinic partner, for team medical
care), player performance, training, coaching and operations supportive programs as listed below:
· Five story atrium and lobby located on the NW corner of the building
· First Team, Second Team and Academy locker rooms
· First Team, Second Team and Academy showers/wet rooms and bathrooms
· First Team, Second Team and Academy coaches’ offices and coaches’ locker rooms,
classrooms, lecture/team theater room and meeting rooms
· First Team player lounge and equipment room
· First Team strength and conditioning, weight and cardio rooms
· Medical training rooms inclusive of hydrotherapy, cryotherapy and steam/sauna rooms
· Equipment storage for soccer and business operations
· Use of existing food preparation and cafeteria spaces4
4 Existing food preparation and service areas may be remodeled/reconfigured and are outside the Sounders’ 50,000
sf interior building area.

The first-floor technical soccer operations suite shall be exclusive to Sounders FC soccer
and business operations and not open to the public. Visiting teams may utilize the Academy or
Defiance locker room and office spaces for training or scrimmages. The First Team areas will not
be open to the public.
The interior of the second floor will include business operations offices, conference rooms
and meeting areas, as well as physical and digital file storage and servers. Sounders FC will
manage business operations, ticket sales, corporate partnership activities, social justice activities,
marketing and media activities and content and brand from these offices. The second-floor space
will include an owners’ suite and executive offices as well as a small break room and will open to
the outdoor deck overlooking the First Team training field (as described above). The second floor
will also include a small locker room and employee shower room for business employee use.
Please see the accompanying Site Plan addressing elements identified at CUP Application
Item #15, including a matrix of conformity with development standards, for additional details
regarding lots sizes, building setbacks, access and circulation plans, including pedestrian access
from each public entrance to the street, parking analysis, open space and landscaping, etc.
g. Proposed off-site improvements (i.e. installation of sidewalks, fire hydrants, sewer
main, etc.):
The proposal includes re-use of an existing office building in an urban area, so the Site is
presently served by sewer, water, road improvements, electrical, etc. Existing off-site
improvements are not planned to be re-constructed, except in the event that code compliance
requires an existing non-conforming improvement to be brought up to current standards. Existing
sewer, water and electrical services will need to be extended into the area of the Site proposed for
development of soccer fields and appurtenant facilities. Hydrants would be installed if required by
the change of use of building 25-20, and/or as needed for new soccer field use and appurtenant
structures.
The Site Plan provides existing internal trails in lieu of frontage improvements. Thus, no
frontage improvements are required as the proposal satisfies RMC 4-6-060.G.2e (authorizing
internal trails).
h. Total estimated construction cost and estimated fmv of the proposed project.
Estimated project cost is $37 million, although that number may vary depending on the
finalization of plans.
i. Estimated quantities and type of materials involved if any fill or excavation is
proposed.
a. Mass excavation: Cut of 4,185 CY and fill of 26,588 CY, net import of 22,403
CY.
b. Field construction for natural grass playing surface 10,300 BCY import. Field
construction for artificial turf playing surface 11,500 BCY.

The fill and excavation figures may be revised as the civil plans are further refined during
the City’s review process.
The natural grass fields will be sand based, with a pea gravel drainage cavity and subsurface
drainage collected and discharged to site civil infrastructure. 10” of Sand growing medium (“root
zone sand”) will be consistent with USGA Standards, as will be the 4” pea gravel drainage cavity.
4” perforated corrugated polyethylene drainage tubing laterals spaced 15’ on center will conduct
stormwater to ridged dual-wall corrugated polyethylene pipe.
The resilient infill synthetic turf product has not yet been selected but it will likely comply
with FIFA Quality Program for Football Turf. The field section will consist of an 8” lift of base
course permeable aggregate and a 2” leveling course of top course permeable aggregate. With the
turf system, this usually results in a standard 12” section.
j. Number, type and size of trees to be removed.
The soccer fields will be developed on land that is presently undeveloped. Some existing
trees and vegetation will need to be cleared for grading and installation of soccer fields, as
discussed in subsection i above. The Arborist Report by American Forest Management dated
August 1, 2022 and submitted under separate cover, addresses existing tree types, counts, and
sizes, required clearing, significant tree retention, and compliance with the current City’s Tree
Ordinance and the City’s updated and more protective Tree Ordinance.
k. Explanation for any land to be dedicated to the City.
No dedications proposed.
l. For shoreline applications only…
Not Applicable, the Site is not within the shoreline jurisdiction for the City of Renton.
m. The proposed number, size, and density of new lots…
Not Applicable, no subdivision is proposed.
