FINDINGS OF FACT
Procedural:
1. Applicant. The Applicant is Unico Properties,1215 4th Ave, Suite 600,Seattle,WA 98161 and
Seattle Soccer, LLC, d/b/a Seattle Sounders FC,406 Occidental Avenue S, Seattle, WA 98104
2. Hearing. A virtual hearing was held on the applications on August 13, 2019 at 11 am in the
City of Renton Council chambers.
3. Project Description. The Applicant requests site plan, conditional use permit and street
modification approval for the integration of a soccer complex for the Seattle Sounders and associated
teams into the Longacres Office Park at 1901 Oaksdale Ave SW, Renton, WA 98057. The proposed
use includes 52,990 square feet of an existing five story 311,982 square foot office building for office
use and indoor training facilities as well as the conversion of an adjoining undeveloped area and some
parking into five full sized outdoor soccer fields and a Goal Keepers Field along with accessory
structures.
The overall project site totals approximately 30 acres. Access to the site would be maintained via
existing curb cuts off Oakesdale Ave SW. A new accessory viewing deck proposed to overlook Field 1
from floor 2 would total approximately 1,650 sq. ft. in area and is designed to accommodate about 100
spectators. Some existing surface parking would be removed for the placement of Fields 1 and 2 and
additional parking would be removed to create a secure 1st team parking area in the existing southern
parking lot. The total remaining parking area would include approximately 766 surface parking stalls.
A maintenance building (approximately 4,000 sq. ft.) and future field restroom (approximately 800 sq.
ft.) are proposed to be co-located between fields 2 and 4.
Of the 52,990 square feet of office space used by the Sounders, they would retain 21,660 sq. ft. as
office use while converting 31,330 sq. ft. of existing office use to indoor recreational use. The indoor
recreational facilities would provide team services space, which is intended to be accessory to the
office and outdoor recreation facilities and would include locker rooms, training space, classrooms and
workspaces, and medical treatment rooms.
The Applicant is requesting a modification from RMC 4-6-060 to retain the existing frontage
improvements along the site’s Oakesdale Ave SW frontage.
4. Adequacy of Infrastructure/Public Services. The project will be served by adequate and
appropriate infrastructure and public services. Since the existing building has been located in an
urbanized area for several years, it is already served by all necessary urban services. The proposed
maintenance building and rest room building will require extension of some services. Services are
more directly addressed as follows:

A. Water and Sewer Service. The project is located within the City’s water and sewer service
areas. The Applicant will be extending water and sewer from the existing mains to the
proposed maintenance building.
B. Fire and Police. The City of Renton will provide police service and the Renton Regional
Fire Authority will provide fire service. Police and Fire Prevention staff indicated that
sufficient resources exist to furnish services to the proposed development with the
improvements and fire impact fees required of the project.
C. Drainage. The proposal provides for adequate and appropriate drainage facilities since
its proposed stormwater controls have been found by City staff to conform to the City’s
stormwater regulations.
The proposal is subject to the 2022 City of Renton Surface Water Design Manual. A
Technical Information Report (TIR) prepared by Coughlin Porter Lundeen, dated August
2022 (Exhibit 12) was submitted with the project application materials to demonstrate
compliance. As detailed in the TIR, the utilizes existing surface water facilities
previously constructed onsite (i.e. Pond B) to be accompanied by installation of a new
onsite drainage system. The proposed drainage system would include a new network of
underground pipes and catch basins, to collect the drainage from the surface and under-
drain system of the proposed sports fields, as well as the surface water runoff from the
walkways and other areas adjacent to the fields within the project site. This system would
direct runoff to a flow splitter that would direct larger flows that do not require water
quality treatment, directly to Pond B. Smaller flows would be directed to the proposed
water quality treatment system. Flows from this facility would also ultimately discharge
into the existing Pond B.
In order to provide the required enhanced basic water quality treatment for the soccer
fields, the project proposes to install a Bioscape open system using Filterra media, along
the western edge of Pond B, downstream of the fields.
D. Parks/Open Space. The proposal provides for adequate parks and open space, since no
such amenities are required by City regulations this type of development and the record
does not establish any demands placed upon such amenities that need to be mitigated.
Despite no parks/open space required of the project, the proposal includes significant
mitigation for any park/open space demand that could be produced by the proposal. The
project site is part of the larger Longacres Office Park, which includes two centrally
located ponds, the south pond, Pond B is a stormwater pond and the north pond has been
classified as a Category II wetland. Both ponds include a trail system around the pond
perimeter and a vegetated with existing mature trees and shrubs.

The project will not displace existing recreational uses. The project proposes minor
modification to the existing pathways on the site. The path that currently connects from
the West side of the Property to Building 25-20 will be removed and new path will be
created at the North edge of the fields to access Building 25-20.
E. Transportation and Circulation. The proposal is served by adequate and appropriate
transportation facilities.
A Trip Generation Memo, prepared by Transportation Engineering Northwest, dated
June 27, 2022 (Exhibit 16) was submitted with the project application materials.
Vehicular access to the site would remain the same, with one (1) signalized access and
one (1) unsignalized access driveway on Oakesdale Ave SW that provide access to the
main parking lot on the south side of the building, and one unsignalized access roadway
that provides access to a visitor parking lot on the north side of the building.
The weekday trip generation estimates for the office use were based on methodology
documented in the Institute of Transportation Engineers (ITE) Trip Generation Manual,
11th Edition for Land Use Code (LUC) 710 (General Office Building). The proposed
outdoor soccer training facility is not consistent with a specific land use category
established in the ITE manual. As such, project-specific information was used for the
average weekday trip generation estimates. To estimate trip generation for the proposed
Sounders training facility, the Applicant provided detailed forecasts of trips anticipated to
occur on a typical weekday based on their operational plan. These weekday trip estimates
are described in the following categories:
Players/Field Use Trips - The fields are anticipated to be used daily from
approximately 8:00 AM to 10:00 PM, however, not all fields will be used
at the same time. The peak usage of the fields and training facility is
anticipated to occur between 10:00 AM and 1:00 PM.
Spectators Trips (Media and Public Session) - On a daily basis, it is
anticipated that media and a select number of visitors may view team
practices on an invitation only basis.
Summer Camp/Clinic Trips - Summer camps run June through August and
would consist of a maximum attendance of 120 students per week, with
camp/clinic hours generally between 9:30 AM and 4 PM Monday through
Thursday and between 9:30 AM and 12:00 PM on Friday.
Weekly Soccer Program Trips - The weekly soccer program consists of a
skills class that would have a maximum attendance of 50 students attending
class three (3) times per week during off peak hours (i.e. 5:30 PM to 7:00
PM).

Based on the trip generation estimates discussed above, it is anticipated that the proposal
will generate 147 total daily trips with a reduction in AM Peak Hour trips by 9 and an
increase in PM Peak Hour trips by 14. As the proposal is not anticipated to generate 20
new AM or PM Peak Hour trips, a Traffic Impact Analysis was not required. A
Transportation Concurrency Test (Exhibit 17) was issued for the proposal, in which it
was concluded that the proposal passed the transportation concurrency test in accordance
with RMC 4-6-070D. It is anticipated that any new trips generated by the proposal would
be adequately mitigated through the payment of a traffic impact fee, currently due at
building permit issuance, therefore no further mitigation is necessary.
The project site includes existing internal vehicular driveways and pedestrian walkways
throughout the site. As testified by Nathan Janders from the City’s Engineering Services
department, public works staff have reviewed the proposed and existing circulation
system and determined that it provides a safe and efficient system for pedestrians and
vehicles. The circulation system is particularly efficient and well planned for the project
as testified by Mr. Proebstle because it provides for direct access from the indoor training
facilities to the soccer fields and also provides for ready building access from the secured
parking spots of the players.
Staff have also determined int the staff report that the proposed circulation system
provides for desirable transitions and linkages between uses, streets, walkways and
adjacent properties. There are existing sidewalks within the Oakesdale Ave SW public
street frontage located along the eastern boundary of the project site, in addition there are
existing pedestrian walkways interior to the project site connecting the existing buildings
and improvements to the public right-of-way and adjacent properties.
F. Schools. The project is not residential in nature. No impacts to schools are anticipated
and no fees are required.
G. Refuse and Recycling. As conditioned, the proposal complies with applicable refuse and
recycling regulations and thus provides for adequate and appropriate facilities to address
solid waste impacts.
In office, educational and institutional developments, a minimum of two (2) square
feet per every one thousand (1,000) square feet of building gross floor area shall be
provided for recyclables deposit areas and a minimum of four (4) square feet per one
thousand (1,000) square feet of building gross floor area shall be provided for refuse
deposit areas. A total minimum area of one hundred (100) square feet is required for
recycling and refuse deposit areas.
Since the project site has an existing five (5)-story office building, totaling 311,982 sq.
ft., with the addition of the proposed 4,000 sq. ft. maintenance building, the proposal
would result in a total of 315,982 sq. ft. of building gross floor area. Based on the

proposed building gross floor area of 315,982 sq. ft., a total of 632 sq. ft. of
recyclables deposit areas would be required and a total of 1,264 sq. ft. of refuse
deposit areas would be required. The location of refuse and recyclable deposit areas
was not included on the submitted site plan application materials, so staff was unable
to verify compliance with this requirement. A condition of approval requires a revised
site plan be submitted showing as existing or proposed the required 632 sq. ft. of
recyclable and 1,264 sq. ft. of refuse deposit areas, or a modification from these
requirements shall be submitted for review and approval.
H. Parking. The proposal provides for adequate and appropriate parking because the
proposed parking complies with the City’s parking standards. City parking standards
require 732 stalls to serve existing Building 25-20 along with the proposed outdoor sports
facilities and the Applicant proposes a total of 766 stalls.
The City’s requirements for off-street parking are based on RMC 4-4-080.F.10.d
(Parking Spaces Required Based on Land Use), depending on the specific land use
category. The minimum code-required off-street parking for the Building 25-20 office
use is 2.0 stalls per 1,000 SF of net building floor area based on the requirements for
offices (general). Based on a total of 284,044 NSF of building area (including the
proposed Sounders FC office use), the minimum parking supply required for Building
25-20 is 568 stalls (2.0 stalls/ 1,000 NSF X 284,044 NSF).
The proposed soccer fields are not consistent with any of the land use categories for
computing required parking under RMC 4-4-080.F.10.d. Therefore, the parking
required for the fields was estimated based on the detailed project-specific trip
generation data and forecasts provided by the owner. To estimate the peak parking
demand of the outdoor soccer training facility on a typical weekday, the detailed
entering and exiting trip generation estimates provided by the owner were assigned to
15-minute periods and the entering minus exiting volume was then used to estimate
the weekday parking accumulation. The trip generation estimates for the proposed
project include players/ field use trips, spectators trips ( media and public sessions),
summer camp/ clinic trips, and weekly soccer program trips. Assuming that the
parking demand associated with the fields is 0 vehicles at midnight, the estimated
peak parking demand for the outdoor soccer training facility use is 164 stalls on an
average weekday (occurring from 9:45 AM to 12:00 PM). Consequently, the
combined Building 25-20 and outdoor soccer facility parking is 732 stalls.
The existing surface parking for Building 25-20 is 929 stalls. The proposal will remove
163 stalls leaving a net total of 766 stalls. The proposed parking satisfies the proposal’s
parking demand.
I. Landscaping. The proposal provides for adequate and appropriate landscaping by
conforming to the City’s landscaping standards.

As shown in the Applicant’s Conceptual Landscape Plan (Exhibit 24), the Applicant is
proposing to satisfy City landscaping requirements through a combination of retention of
existing landscaping and the planting of new landscaping.
Landscaping requirements primarily apply to street frontage and parking areas. RMC 4-
4-070F1 requires ten feet of landscaping along street frontages. There is an existing
landscape strip along the street frontage that is comprised of mature trees, shrubs, and
ground cover. This existing landscape strip has a minimum width of approximately 13
feet and would satisfy the requirement for a minimum ten-foot (10’) wide landscape strip
along the street frontage.
City regulations require an extensive amount of landscaping in parking areas. According
to the Applicant’s parking analysis, (Exhibit 25), after proposed modifications to the
parking lot, the proposed facilities will be served by 766 parking spaces. RMC 4-4-
070F6b requires 35 square feet of landscaping per parking stall for parking lots with over
100 parking spaces, which totals 26,810 sq. ft. of interior parking lot landscaping. As
shown on the submitted conceptual landscape plan, the existing and proposed interior
parking lot landscaping would total approximately 27,700 sq. ft., which would exceed the
26,810 sq. ft. requirement.
The Applicant’s landscaping plans, Ex. 24, show that the proposed facilities are shielded
from view and adjoining uses by perimeter landscaping and critical areas that surround
the site on all sides.
The staff report provides a more detailed discussion of how the proposal complies with
other landscaping requirements.
J. Transit and Bicycle. The proposal complies with City bicycle parking requirements and
thus provides for adequate bicycle facilities. As testified by Ms. Ding, the proposal is
served by adequate transit as a Sounder station is located close to the facility and the
proposed development will not result in any interference with existing transit stops.
RMC 4-4-080F11a requires bicycle parking spaces at the rate of 10% of required
automobile parking spaces, which results in a required 16 parking spaces for the 164 new
automobile spaces required of the proposal for the newly proposed facilities (limited to
the proposed outdoor recreational use – the existing building does not trigger new bicycle
parking requirements). Bicycle parking was not included in the application materials. A
condition of approval requires a revised site plan that includes the required 16 parking
spaces.

5. Adverse Impacts. There are no significant adverse impacts associated with the proposal. On
November 7, 0222 the City issued a Mitigated Determination of Non-significance (MDNS) for the
project. Upon reconsideration, the MDNS was re-issued on December 5, 2022 to revise a mitigation
measure addressing the water quality impacts of proposed synthetic turf. The MDNS was not timely
appealed. Adequate infrastructure serves the site as determined in Finding of Fact No. 4. Impacts are
more specifically addressed as follows:
A. Views. It is not anticipated that the proposal will result in any material obstruction of
views. The only views are internal to the site from Building 25-20. The views from the
lower level of Building 25-20 will be altered by a 10’ tall fence, privacy screen and ball
control netting. The light posts will also minimally change the view from Building 25-20
to the West. Views from the Longacres Campus trails will be altered by the fence and ball
control netting in some sections when looking to the East. According to the staff report,
the proposal would not block view corridors to shorelines or Mt. Rainier.
B. Compatibility. The proposal is compatible with surrounding use. Adjacent properties
include medical offices, daycare, and commercial airlines uses, and are separated from
the project site by right of way and undevelopable land. The adjoining property to the
north is another Longacres Business Park office building, buffered from the sports field
by a Category II wetland and separated from the sports fields by a minimum of 500 feet.
The adjoining parcel to the west is composed of Wetland A and the parcel west of that is
an undeveloped parcel in the Longacres Business Park. The closest property to the south
is the Kaiser Permanente property, which is separated from the sports fields by a
vegetated buffer and an existing stormwater pond. The east side of the sports fields is
adjoined by Oakesdale Ave SW, which is a five-lane arterial. Sidewalks, bike lanes and
street trees provide further separation. There are four lots across from Oakesdale. One of
the lots is developed with a daycare center, the remaining three are undeveloped.
C. Light, glare, noise and privacy. The proposal will not create any significant adverse light,
noise or glare impacts and will not impact privacy.
The only new lighting impacts will result from proposed field lighting. Within the field
complex, light poles will be erected, containing directional LED lights designed
specifically to light fields after dark and directed solely downward onto the fields and
preventing light pollution outside of the field complex. Use of field lights is generally
restricted to when it is needed for visibility during evening training sessions, or possibly
off -hours maintenance activities. Evening training most frequently occurs on turf fields
(which are the furthest from Wetland A) for the MLS Next Academy Team. These
sessions typically run from 4:00 - 9:00 pm, so the duration of lighting depends upon the
time of year. For example, a winter training session may require 5 hours of lighting,
where a summer session might not require any. Occasionally, lighting may be used

during special events on any field. Given the absence of any sensitive land uses in the
vicinity as described in Finding of Fact 5B, the modern technology involved in LED
lighting and the limited hours of use, the light and glare created by the project is not
found to be significant.
The surrounding landscaping and critical areas and the nature of surrounding uses
provides for adequate protection of privacy for both those using the fields and
surrounding uses, as well as assisting in noise reduction. The proposed soccer fields
would be located to the interior of the project site and would be buffered along the north
and west by existing wetlands and stormwater facilities that are vegetated with mature
vegetation and would be buffered along the east by the existing office building, surface
parking lot, and mature vegetation, and along the south by existing stormwater facilities
and existing mature vegetation. As testified by Mr. Proebstle, the soccer fields will be
surrounded by a ten foot fence to ensure that experimental soccer plays and the like will
be hidden from public (and competing teams) view. As noted in Finding of Fact No. 5B,
in terms of privacy there is no residential or similar development close enough to be
adversely affected by noise or privacy impacts.
D. Critical Areas. A portion of the playfields will be within the buffer of a Category II
wetland. The proposal is also in a flood hazard area and a seismic hazard area. As
mitigated, the proposal complies with the City’s critical area regulations and thus is not
found to adversely affect critical areas.
i. Seismic Hazard. A high seismic hazard is mapped on the project site. RMC 4-3-
050F2aii requires the Applicant to submit a geotechnical report for high seismic areas
that establishes that the site can safely accommodate the proposal and that the
proposal will not jeopardize other critical areas or destabilize adjoining properties.
The Applicant has complied with RMC 4-3-050F2aii and for this reason there are no
adverse impacts anticipated due to the presence of the seismic hazard area.
As required, the Applicant submitted a Geotechnical Engineering Services Draft
Report, prepared by GeoEngineers, (dated June 23, 2022; Exhibit 6). According to the
geotechnical report, the loose to medium dense sand which underlies the project site
has a moderate to high risk of liquefying. The existing fill and alluvial deposits
encountered in the explorations contain a high percentage of fines and are highly
moisture sensitive. It is anticipated that the operation of equipment on these soils
would be difficult during the wet season (typically October through May) and in wet
weather conditions. In addition, the report recommends that the design of the fields
consider estimated site settlement due to the presence of the underlying fill and
alluvial deposits. In addition to being susceptible to liquefaction, the alluvial soils are
compressible and are expected to settle under new/increased loading conditions.
Static settlements will depend on the thickness of new fill placed.

The report included recommendations for site preparation and earthwork, excavations
and permanent slopes, utility trenches, pavement recommendations, and
recommended additional geotechnical services for the construction of the proposed
fields, however the report did not include a discussion on the proposed maintenance
building and elevated exterior patio addition. Due to the concerns expressed in the
geotechnical report regarding soil stability on the project site, a SEPA mitigation
measure requires that construction on the project site comply with the
recommendations of the report. The Applicant's geotechnical engineer is required to
review the project's construction plans for the new fields and the building permit
plans for the proposed maintenance building and elevated patio addition to verify
compliance with the submitted geotechnical report. The geotechnical engineer shall
submit a sealed letter stating that he/she has reviewed the construction and building
permit plans and in their opinion the plans and specifications meet the intent of the
report.
ii. Wetlands. The proposed soccer fields will encroach into a buffer of a Category II
wetland. The Applicant proposes mitigation that staff have found to conform to
critical area regulations.
A Critical Areas - Existing Conditions Letter Report prepared by Talasaea, dated
April 29, 2022 (Exhibit 7) and a Critical Areas Report and Conceptual Mitigation
Plan prepared by Talasaea, dated October 7, 2022 (Exhibit 8) were submitted with the
project application materials. The critical areas reports identified Wetlands A and F,
Pond B, Feature D, and Feature G on the project site. Wetland A is located along the
eastern boundary of the project site and would be classified as a Category II wetland
with a moderate habitat score. Wetland F is located to the north of the project site and
would also be regulated as a Category II wetland with a moderate habitat score.
Category II wetlands with a moderate habitat score require a 100-foot buffer for low
impacts land uses and a 150-foot buffer for all other land uses.
Pond B is a stormwater detention and treatment pond located directly south of
Wetland A, along the east side of the project site, and would not be classified as a
regulated wetland. Pond B hydrology is provided by direct surface flow during rain
events and from the stormwater detention pond located to the south.
Feature D is an upland area located upslope and east of Pond B. Both test plots
conducted within Feature D failed to satisfy the requirements of a hydrology indicator
for wetlands, and one (1) of the two (2) test plots failed to satisfy the requirements of
either a hydrology or hydric soil indicator. Feature D hydrology, when present,
appears to be historically provided by an installed irrigation system which draws
water directly from Pond B. Aside from the installed irrigation system, hydrology
can only otherwise be provided by direct precipitation due to local topography.
Feature D is an area that is indicative of intentional plantings designed to mak e the

area visually appear as a wetland. Feature D would not be classified as a regulated
wetland.
The submitted Critical Areas - Existing Conditions Letter Report (Exhibit 7) was
reviewed by the City’s environmental consultant, Otak. Otak’s findings were
summarized in a Peer Review Memorandum, dated June 9, 2022 (Exhibit 9). Otak
concurred with the assessment and delineation of Wetlands A and F and also
concurred that Pond B, Feature D, and Feature G would not be classified as regulated
wetlands.
The proposed site plan (Exhibit 2) shows the proposed keeper/training area and Field
1 within the 100-foot buffer of Wetland A. The proposal would have no direct impact
to Wetland A, although it would reduce the 100-foot buffer to approximately 32 feet,
resulting in the alteration of approximately 15,467 sq. ft. of Wetland A’s buffer. The
maximum buffer reduction permitted by the City’s adopted Critical Areas Regulations
is 25% or a 25-foot reduction of a 100-foot buffer (RMC 4-3-050I). The proposal
would result in an approximately 68% reduction in the standard buffer, which is
greater than the buffer reduction permitted by the City’s Critical Areas Regulations.
Following the guidelines outlined by the Washington State Department of Ecology
Publication 21-06-003, the alteration would be achieved through the use of Wetlands
as Buffers (often referred to as “paper fill”). Conversion of wetland into buffer does
not actually fill any wetland; wetland converted into buffer still functions as a wetland
in the landscape. To mitigate for the “paper fill” impacts to Wetland A, the proposal
would be required to comply with the City’s Critical Areas Regulations for
Alterations to Wetlands (RMC 4-3-050J.4) and provide the appropriate mitigation
ratio for indirect wetland impacts. The Applicant’s Conceptual Mitigation Plan
(Exhibit 8) would include the purchase of credits from the Springbrook Creek
Wetland Mitigation Bank. The Applicant proposes a mitigation ratio of 50% (i.e.,
0.5:1.0) for its indirect impact to Wetland A that causes no or only partial loss of
ecological functions to the wetland. In addition, the Applicant is proposing to enhance
the upland buffer of Wetland A existing between the proposed field locations and the
wetland edge, an area of approximately 15,151 sq. ft. in size. Most of this buffer area
is in good ecological condition; however, some areas are dominated by invasive plant
species and would benefit from enhancement. The proposed area of buffer
enhancement would total approximately 4,616 sq. ft. within the 15,151 sq. ft. buffer
area.
Secondary review of the Critical Areas Report and Conceptual Mitigation Plan
(Exhibit 8) was conducted in a Peer Review Memorandum, prepared by Otak, dated
November 2, 2022 (Exhibit 10). The Peer Review Memorandum notes that the
submitted Mitigation Plan proposes no direct impacts to Wetland A, and 15,467 sq. ft.
of indirect impacts into the Wetland A buffer. Mitigation of these imp acts is proposed
through a combination of mitigation credit purchase through the Springbrook Creek
Mitigation Bank at a 0.5:1 ratio, and 4,616 square feet of buffer enhancement in areas

of the Wetland A upland buffer dominated by invasive species. The proposed buffer
enhancements would be subject to maintenance and monitoring for a period of five
(5) years per RMC 4-3-050L(2) and RMC 4-3-050L(3). In general, the Peer Review
Memorandum (Exhibit 10) takes no issue with the proposed mitigated strategy,
however there were some outstanding comments that needed to be addressed prior to
formal approval. A condition of approval requires, that a final mitigation plan be
submitted addressing the recommendations outlined in the Peer Review
Memorandum, prepared by Otak, dated November 2, 2022 (Exhibit 10). The final
mitigation plan shall be submitted to the Current Planning Project Manager for review
and approval at the time of Construction Permit Review. Staff further recommends,
that the purchase of mitigation bank credits be completed prior to the commencement
of any paper fill activities on the project site.
Fencing and critical areas signage are required by RMC 4-3-050G.3). A condition of
approval requires that a fencing and signage detail be submitted at the time of
Construction Permit review to the Current Planning Project Manager for review and
approval. In addition, onsite critical areas are required to be placed in a Native
Growth Protection Easement (NGPE). A condition of approval requires that any
portion of the onsite wetland and associated buffer areas be placed within a recorded
NGPE.
The Washington State Department of Ecology (DOE) submitted an email on
December 20, 2022 (Exhibit 27) asserting that Feature G should be regulated as a
wetland and that the filling of these wetland would trigger state and federal permitting
requirements. A response from the City’s peer review consultant Otak (Exhibit 28)
maintains that Feature G does not meet the definition of a wetland. The Applicant’s
wetlands consultant, Talasaea, arrived at the same conclusion based upon both its
application of applicable wetland definitions and indirect assessment of wetland
indicators. See Ex. 34 and 35.
Feature G is determined to not qualify as a wetland under the RMC 4-11-230 wetland
definition, specifically the portion that exempts water bodies “created after July 1,
1990, that were unintentionally created as a result of the construction of a road,
street, or highway.’ The Otak and Talasaea reports, Ex. 28, 34 and 35, conclusively
establish that Feature G was unintentionally created as a result of road and building
construction. As detailed in those reports, Feature G resulted from the ungraded
filling of a stormwater pond designed to accommodate run off from road and building
construction of the Longacres business park facilities after 1990. The only ambiguity
in application of the road construction exemption is whether the exemption still
applies if the stormwater comes from both road and building construction as opposed
to just the road construction. There is no Washington case law on this issue. The
Otak and Talasaea reports take the position that Feature G does not qualify as a
wetland under the road construction exemption. According to the testimony of Ms.
Ding, DOE was supplied a copy of the Ex. 28 Otak report and did not respond. Given

the expertise and peer review objectivity of Otak, the lack of response from DOE and
the corroboration from Talasaea, it is concluded that Feature G does not qualify as a
wetland under the road construction exemption even if it partially originated from
building construction in addition to road construction.
iii. Floodplain. The project site is located within the 100-year floodplain of Springbrook
Creek and the proposal includes the placement of fill within this floodplain. The
City’s critical area regulations require the Applicant to compensate for the added fill
by creating additional flood capacity within the floodplain. The Applicant has
provided for the added flood capacity as required and thus the proposal is found to
adequately mitigate against flood impacts.
A Civil Engineering Narrative, prepared by Coughlin Porter Lundeen, dated August
8, 2022 (Exhibit 11) was submitted with the project application materials and
included a discussion on the grading proposed within the floodplain. The proposed
project would include approximately 575,000 sq.ft. of sports fields, which will result
in the placement of approximately 718,000 cubic feet of fill within the currently
delineated 100-year floodplain. As required by the City's Critical Areas Regulations,
floodplain fill mitigation would be required in the form of compensatory storage
below the record Base Flood Elevation (BFE). This BFE is listed as at 20 -foot
elevation at the southern area of the Sounders fields, and roughly 19.6 to 19.7 at the
northern edge. The compensatory mitigation proposal would be to calculate the
proposed compensatory volume using a BFE of 20.0 across the entire field project
limits, which would exceed the minimum volume required.
The required compensatory volume is proposed to be provided using a series of
underground storage chambers (StormTech or Eq) to hold the required flood plain fill
mitigation volume of floodwater. These chambers would connect to open, screened
inlet/outlet pipes that extend below the Pond B water surface. The chambers would
begin to store replacement flood volume when the pond elevation reaches its
maximum detention water surface elevation of 14.7 feet. A discussion of whether the
proposed compensatory storage would adversely impact salmonids, ensuring they do
not get trapped within this system was not included. Therefore, a SEPA mitigation
measure requires that the Applicant demonstrate that the proposed underground
storage chambers not have an adverse impact on salmonids and ensures that
salmonids would not get trapped within the proposed underground storage chambers
iv. Fish and Wildlife Habitat Area. The Applicant submitted a Critical Areas Report and
Conceptual Mitigation Plan prepared by Talasaea, dated October 7, 2022 (Exhibit 8),
which included a Biological and Habitat Assessment. The Biological and Habitat
Assessment identifies Endangered Species Act (ESA) listed or candidate species
potentially within the Project-affected areas or maybe affected by the proposed action.
Species listed under the Endangered Species Act fall under the jurisdiction of the U.S.

Fish and Wildlife Service (USFWS) for terrestrial and freshwater species, and the
National Oceanographic and Atmospheric Administration (NOAA) and National
Marine Fisheries Service (NMFS) for marine and anadromous species.
The NOAA Fisheries website and Washington Department of Fish and Wildlife's
(WDFW) Priority Habitats and Species (PHS) website were used to review listed
species within the vicinity of the project site. Two (2) ESA-listed Pacific salmon
species are potentially within the Project-affected area, or may be affected by the
proposed action: Puget Sound Chinook (Oncorhynchus tshawytscha), designated as
Threatened, and Puget Sound Steelhead (Oncorhynchus mykiss) designated as
Threatened. There is final designated critical habitat for both salmon species within
the Project-affected area, Springbrook Creek. Springbrook Creek is approximately
1,150 feet from the project site.
The Critical Areas Report (Exhibit 8) concludes that the proposed construction and
operation of the Sounders facilities would not directly affect any of the above or any
other ESA-listed species. The entirety of the site development work takes place in an
existing urban area with no significant habitat features for any of the species listed
above. The project site is located nearly 1,900 feet from the Green River and is
outside of its drainage basin. While the project site is located within the Springbrook
Creek/Black River subbasin area, it is approximately 1,150 feet from Springbrook
Creek and has no direct connection or impact to Springbrook Creek. However,
secondary review of the Applicant's Critical Areas Report was conducted by the
City's Environmental Consultant (Otak). Concerns were expressed regarding the fill
that would be placed within the synthetic fields. There are some fill materials that
may be toxic to fish. To ensure that the fill placed within the synthetic turf fields does
not adversely impact fish species, a SEPA mitigation measure has been imposed that
requires the field materials to not result in a probable significant impact upon fish and
wildlife and that water quality be monitored for a five-year period.
v. Aquifer Recharge. Staff testified at hearing that the proposal is not located in a
mapper aquifer recharge area.
6. Tree Retention. Beyond the City’s critical area regulations, the only regulations requiring
protection of vegetation are the City’s tree retention standards. The project involves the removal of
377 trees. However, this removal is consistent with the City’s tree retention standards and thus is not
found to create any adverse impacts due to the loss of trees.
The City's tree retention standards require thirty percent (30%) retention of onsite significant trees
(after the deduction of trees within areas of public right-of-way dedication and critical areas and
buffers). The Applicant submitted an arborist report, Exhibit 13, that demonstrates compliance with

this standard. According to the report, there are a total of 605 significant trees on the project site, of
those 24 would qualify as high-risk trees, resulting in 581 viable significant trees on the project site, of
which two (2) cottonwood trees would be considered landmark trees. The proposal would include the
removal of 377 trees (including one (1) landmark tree) for the development of the proposed soccer
fields, resulting in the retention of 204 trees and one landmark trees. The proposal to retain 204
significant trees would result in a retention percentage of thirty five percent (35%), which exceeds the
City's minimum tree retention requirements.
The City's Tree Retention Regulations also require that a minimum tree density of 30 credits per net
acre. The arborist report (Exhibit 13) included a tree density calculation and concluded that the
retained trees would result in the provision of 30.2 tree credits on the project site, which would satisfy
the minimum tree density requirements.
Conclusions of Law
1. Authority The site plan and conditional use permit require hearing examiner review and final
approval. The street modification request is subject to staff approval when reviewed separately, but is
consolidated with hearing examiner review for this application.
RMC 4-9-200D2bvi requires a public hearing before the hearing examiner for site plan applications
involving projects over 10 acres in size. RMC 4-9-200F9b requires the hearing examiner to issue a
written decision after holding the hearing. RMC 4-2-060 requires a hearing examiner conditional use
permit for outdoor recreational facilities. RMC 4-8-080G classifies hearing examiner site plan and
hearing examiner conditional use permit applications as Type III applications. RMC 4 -8-080G
classifies the street modification request as a Type I application.
RMC 4-8-080(C)(2) requires consolidated permits to be collectively processed under “the highest -
number procedure.” The Type III review is the “highest-number procedure” and therefore must be
employed for the conditional use, site plan and street modification applications. As outlined in RMC 4-
8-080(G), the hearing examiner is authorized to hold hearings and issue final decisions on Type III
applications subject to closed record appeal to the Renton City Council.
2. Zoning/Design District/Comprehensive Plan Designations. The subject property is zoned
Commercial Office (CO), its comprehensive plan land use designation is Employment Area (EA) and
the project site is located in Design District D.
3. Review Criteria/Adoption of Staff Findings and Conclusions of Street Modifications.
Conditional use criteria are governed by RMC 4-9-030(D). Site Plan criteria are governed by RMC 4-
9-200.E.3. All applicable review criteria for the conditional use and site plan applications are quoted
below in italics and applied through corresponding conclusions of law.
The criteria for street modification requests identified in Finding of Fact No. 3 are governed by RMC 4-
9-250.D.2. The findings and conclusions of Finding No. 21 of the staff report are adopted by this
reference in full to conclude that all review criteria for the requested street modification are met.

CONDITIONAL USE
The Administrator or designee or the Hearing Examiner shall consider, as applicable, the following
factors for all applications:
RMC 4-9-030(C)(1): Consistency with Plans and Regulations: The proposed use shall be
compatible with the general goals, objectives, policies and standards of the Comprehensive Plan, the
zoning regulations and any other plans, programs, maps or ordinances of the City of Renton.
4. As conditioned, the proposal is consistent with all applicable comprehensive plan policies and
development standards as outlined in Findings No. 17-19 of the staff report, adopted by this
reference as if set forth in full. The site is located within the Urban Design District D overlay,
however in accordance with RMC 4-2-120B the Urban Design Regulations are only applicable to
residential mixed-use buildings within the CO zone. As the proposal does not include any residential
mixed-use buildings the Urban Design Regulations would not apply to this proposal.
RMC 4-9-030(C)(2): Appropriate Location: The proposed location shall not result in the
detrimental overconcentration of a particular use within the City or within the immediate area of the
proposed use. The proposed location shall be suited for the proposed use.
5. For the reasons identified in Finding of Fact No. 4 and 5, the proposal is compatible with
surrounding uses, will be served by adequate infrastructure and will not create significant adverse
impacts to adjoining properties. For these reasons the proposed location is suited for the proposed
use. No other similar uses are located anywhere in the vicinity so the proposal does not result in a
detrimental overconcentration of use.
RMC 4-9-030(C)(3): Effect on Adjacent Properties: The proposed use at the proposed location
shall not result in substantial or undue adverse effects on adjacent property.
6. As determined in Finding of Fact No. 5, as conditioned, there are no significant adverse
impacts associated with the proposal, so it will not result in substantial or undue adverse effects on
adjacent property.
RMC 4-9-030(C)(4): Compatibility: The proposed use shall be compatible with the scale and
character of the neighborhood.
7. As determined in Finding of Fact No. 5B, the proposed use is compatible with the scale and
character of the neighborhood.
RMC 4-9-030(C)(5): Parking: Adequate parking is, or will be made, available.
8. As determined in Finding of Fact No. 4H, the site is served by adequate parking.
RMC 4-9-030(C)(6): Traffic: The use shall ensure safe movement for vehicles and pedestrians and
shall mitigate potential effects on the surrounding area.

9. As outlined in Finding of Fact No. 4E, the proposal provides for safe circulation and adequate
traffic mitigation and facilities.
RMC 4-9-030(C)(7): Noise, Light and Glare: Potential noise, light and glare impacts from the
proposed use shall be evaluated and mitigated.
10. As determined in Finding of Fact No. 5C, the proposal will not result in any adverse light,
noise or glare impacts.
RMC 4-9-030(C)(8): Landscaping: Landscaping shall be provided in all areas not occupied by
buildings, paving, or critical areas. Additional landscaping may be required to buffer adjacent
properties from potentially adverse effects of the proposed use.
11. The criterion is met as interpreted by staff. The project area on the south end to the south end
is not developed and not within a critical area. Ms. Ding testified that this undeveloped site is not
artificially landscaped but is populated by vegetation. She testified that staff considers the naturally
growing vegetation to qualify as landscaping. Deference is given to staff’s interpretation on this
issue as it appears to be consistent with past practice and alleviates the heavy burden the requirement
would otherwise place on developers only developing small portions of large development sites. To
require such sites to be fully landscaped in the more traditional meaning of the term would result in
the loss of ecological benefit of retention of natural habitat while at the same time placing large
installation and maintenance costs upon the property owner.
SITE PLAN
RMC 4-9-200(E)(3): Criteria: The Administrator or designee must find a proposed project to be in
compliance with the following:
a. Compliance and Consistency: Conformance with plans, policies, regulations and approvals,
including:
i. Comprehensive Plan: The Comprehensive Plan, its elements, goals, objectives, and
policies, especially those of the applicable land use designation; the Community Design

RMC 4-9-200(E)(3)(b): Off-Site Impacts: Mitigation of impacts to surrounding properties and
uses, including:
i. Structures: Restricting overscale structures and overconcentration of development on a
particular portion of the site;
ii. Circulation: Providing desirable transitions and linkages between uses, streets, walkways
and adjacent properties;
iii. Loading and Storage Areas: Locating, designing and screening storage areas, utilities,
rooftop equipment, loading areas, and refuse and recyclables to minimize views from
surrounding properties;
iv. Views: Recognizing the public benefit and desirability of maintaining visual accessibility to
attractive natural features;
v. Landscaping: Using landscaping to provide transitions between development and
surrounding properties to reduce noise and glare, maintain privacy, and generally enhance the
appearance of the project; and
vi. Lighting: Designing and/or placing exterior lighting and glazing in order to avoid
excessive brightness or glare to adjacent properties and streets.
13. As conditioned, the criteria quoted above are met. As outlined in Finding of Fact No. 4E, the
proposal provides for desirable transitions and linkages between uses, streets, walkways and adjacent
properties. As determined in Finding of Fact No. 4G, the proposal complies with the City’s refuse
and recycling standards. As determined in Finding of Fact No. 5A, the proposal will not adversely
affect any views. As determined in Finding of Fact No. 4I, the proposal is consistent with the City’s
landscaping standards, which includes perimeter landscaping to provide buffering to adjacent uses.
The proposal will not create any significant light impacts, including excessive brightness or glare, for
the reasons identified in Finding of Fact No. 5C.

iv. Landscaping: Use of landscaping to soften the appearance of parking areas, to provide
shade and privacy where needed, to define and enhance open spaces, and generally to enhance
the appearance of the project. Landscaping also includes the design and protection of planting
areas so that they are less susceptible to damage from vehicles or pedestrian movements.
14. The criteria quoted above are met. Privacy impacts are adequately addressed as identified in
Finding of Fact No. 5. Due to compliance with the City’s critical areas ordinance, there are no
natural features adversely affected by the proposal. As identified in the Applicant’s landscaping
plans, Ex. 24, and addressed in Finding of Fact No. 4I, significant landscaping is proposed within the
parking area as required to city regulations to protect soften the appearance of parking areas. As
noted in Finding of Fact 5C, the landscaping also provides for privacy. The landscaping plans, Ex.
24, show that the landscaping surrounds the soccer fields, thus defining and enhancing that open
space. The extensive amount of landscaping required and proposed clearly enhances the appearance
of the project. City landscaping standards include specifications to ensure that they are protected
from damage caused by vehicles and pedestrians.
RMC 4-9-200(E)(3)(d): Access and Circulation: Safe and efficient access and circulation for all
users, including:
i. Location and Consolidation: Providing access points on side streets or frontage streets
rather than directly onto arterial streets and consolidation of ingress and egress points on the
site and, when feasible, with adjacent properties;
ii. Internal Circulation: Promoting safety and efficiency of the internal circulation system,
including the location, design and dimensions of vehicular and pedestrian access points,
drives, parking, turnarounds, walkways, bikeways, and emergency access ways;
iii. Loading and Delivery: Separating loading and delivery areas from parking and pedestrian
areas;
iv. Transit and Bicycles: Providing transit, carpools and bicycle facilities and access; and
v. Pedestrians: Providing safe and attractive pedestrian connections between parking areas,
buildings, public sidewalks and adjacent properties.
15. The proposal as conditioned provides for safe and efficient access and vehicular and pedestrian
circulation as required by the criterion above for the reasons identified in Finding of Fact No. 4E. As
testified by staff, the proposal is not subject to new loading and delivery standards since the
development is largely pre-existing. Transit and bicycle facilities are available as determined in
Finding of Fact No. 4J.
RMC 4-9-200(E)(3)(e): Open Space: Incorporating open spaces to serve as distinctive project
focal points and to provide adequate areas for passive and active recreation by the occupants/users
of the site.
