PROJECT NAME/NUMBER: PR21-000476 VMAC Natural Grass Resurfacing
Project / LUA21-000448, SME, ECF
PROJECT LOCATION: 12 Seahawks Way Renton, WA 98056 (APNs 292405-
9001 and -9015)
APPLICANT/PROJECT CONTACT PERSON: Sean Vanos, Director of Facility Operations / seanv@seahawks.com / 12
Seahawks Way Renton, WA 98056
LOCATION WHERE APPLICATION MAY BE
REVIEWED:
Applicant documents are available online through the City of Renton
Document Center website. See also https://bit.ly/3slnxjZ
PROJECT DESCRIPTION: The applicant is requesting a Shoreline Exemption and Environmental (SEPA) Review to
resurface the natural grass fields at the Virginia Mason Athletic Center (VMAC). The site is located at located at 12
Seahawks Way in the Commercial Office Residential (COR) zone. The project proposal includes excavation of
approximately 250,000 square feet of sand and organic material deposited on three outdoor practice fields via regular
maintenance activities and grading of existing topsoil and reinstallation of new turf/sod. The outdoor fields are partially
within the 200-foot shoreline area along Lake Washington. No native soils or soils associated with the existing three-foot
(3’) soil cap layer would be disturbed. Excavated material would be transported using small dump trucks to a barge via
temporary access ramp and steel plating on a 16-foot-wide section of VMAC’s shoreline for offsite disposal. The project
is proposing to compensate for the buffer impacts by enhancing approximately 480 square feet of buffer after
completion of the field resurfacing.
Appeals of the environmental determination must be filed in writing on or before 5:00 p.m. on January 24, 2022.
Appeals to the Examiner are governed by RMC 4-8-110 and more information regarding the appeal process may be
obtained from the Renton City Clerk’s Office, (425) 430-6510. Due to the ongoing state of emergency enacted by
Governor’s Proclamation 20-05, the City Clerk’s Office is working remotely. For that reason, appeals must be submitted
electronically to the City Clerk at cityclerk@rentonwa.gov or delivered to City Hall 1st floor Lobby Hub only on Tuesdays
and/or Wednesdays. The appeal fee, normally due at the time an appeal is submitted, will be collected at a future date
if your appeal is submitted electronically. Appeals to the Hearing Examiner are governed by RMC 4-8-110 and additional
information regarding the appeal process may be obtained from the City Clerk’s Office, cityclerk@rentonwa.gov.
PUBLIC HEARING: If the Environmental Determination is appealed, a public hearing will be set and all parties notified.

ENVIRONMENTAL (SEPA) DETERMINATION OF
NON-SIGNIFICANCE - MITIGATED (DNS-M)
Project File Numbers: PR21-000476 / LUA21-000448, SME, ECF
Project Name: VMAC Natural Grass Resurfacing Project
Applicant: Sean Vanos, Seattle Seahawks, 12 Seahawks Way, Renton, WA 98056
Project Location: 12 Seahawks Way, Renton, WA 98056 (APNs 2924059001 and 2924059015)
Project Description: The applicant is requesting a Shoreline Exemption and Environmental (SEPA) Review to
resurface the natural grass fields at the Virginia Mason Athletic Center (VMAC). The
VMAC is located at 12 Seahawks Way in the Commercial Office Residential (COR) zoning
designation. The project proposal includes excavation of approximately 250,000 square
feet of sand and organic material deposited on three outdoor practice fields via regular
maintenance activities over the last 14 years and grading of existing topsoil and
reinstallation of new turf/sod. The outdoor fields are partially within the Shoreline High
Intensity designation associated with Lake Washington Reach C. A portion of the work
would occur within the shoreline designated area located approximately 200 feet from
the ordinary high water mark (OHWM). No native soils or soils associated with the
existing three-foot (3’) soil cap layer would be disturbed. Excavated material would be
transported using small dump trucks to a barge via temporary access ramp and steel
plating on a 16-foot-wide section of VMAC’s shoreline for offsite disposal. The excavated
material would be recycled in the production of topsoil at a port facility in Tacoma.
Shoreline plants located within the existing restored shoreline buffer would be
transplanted from the ramp zone to avoid damage and reinstalled after the project is
completed. One (1) existing balsam poplar tree within the barge ramp area has the
potential to be removed within the shoreline buffer. The project is proposing a mitigation
plan to compensate for the buffer impacts by enhancing approximately 480 square feet
of shoreline buffer after completion of the field resurfacing. The field maintenance
project would commence after the Seattle Seahawks football season and is anticipated
to take 5 to 7 days to complete. The applicant submitted a Technical Memorandum with
the application.
