existing building.
7. There is an existing 6-inch fire service with a DDCVA serving the existing building.
8. Based on the review of project information submitted for the pre -application meeting, Renton
Regional Fire Authority determined the preliminary fire flow is 3,750 GPM and that a minimum of
three hydrants is required. Per City code a looped water main is required around the building or
complex of buildings when the fire flow demand exceeds 2,500 GPM.
9. Based on the information provided with the pre-application submittal documents, the following
developer’s installed water main improvements will be required to provide domestic and fire
protection service to the redevelopment including but not limited to the items that follow:
a. The proposed new hospitality suite and east expansion appear to be within the
existing easement or within 10 feet of the existing water main. If either the proposed
structure or expansion are within the above referenced areas then, the proposed
structures shall be relocated, or, the existing water main shall be relocated. If
electing to relocate the water main then a partial release of easement and a new
easement would be required.
b. To comply with clearance requirements, the building footprints and foundations for
both the proposed west infill and the east expansion must maintain a minimum
horizontal separation of 10 feet from the existing water mains.
c. A 15 foot wide public water easement is required for any public water main, hydrant
and water meter located outside City right-of-way. A minimum 10-foot setback is

d. The existing 4-inch domestic water meter may be re-used if it can be shown that the
meter size meets the requirements of the Uniform Plumbing Code. Sizing shall be
included with the building permit application.
e. If the proposed hospitality suite will require domestic water service then a new
domestic water service, minimum 1-inch, meter and backflow prevention shall be
required.
f. Installation of fire hydrants. The location and number of hydrants will be determined
by the RRFA based on the final fire flow demand and final site plan. See RRFA
comments for additional hydrant spacing requirements.
g. Any existing hydrant that is counted toward meeting the minimum required or hydrant
spacing shall be equipped with a 5-inch STORZ fitting if not already equipped with
one.
h. Per the Uniform Plumbing Code a pressure reducing valve (PRV) is required
downstream of the domestic water meter(s) because the water pressure is over 80
PSI.
10. Civil plans for the water main improvements will be required and must be prepared by a
professional engineer registered in the State of Washington. Please refer to City of Renton

TO: Pre-Application File No. PRE25-000170
FROM: Jill Ding, Senior Planner
SUBJECT: VMAC Expansion Study –
12 Seahawks Way, Renton, WA 98056
APN 2924059015
General: We have completed a preliminary review of the pre-application for the above-
referenced development proposal. The following comments on development and
permitting issues are based on the pre-application submittals made to the City of
Renton by the applicant and the codes in effect on the date of review. The applicant is
cautioned that information contained in this summary may be subject to modification and/or
concurrence by official decision-makers (e.g., Hearing Examiner, Community & Economic
Development Administrator, Public Works Administrator, Planning Director, Development
Services Director, Development Engineering Director, and City Council). Review comments
may also need to be revised based on site planning and other design changes required by
City staff or made by the applicant. The applicant is encouraged to review all applicable
sections of the Renton Municipal Code. The Development Regulations are available online
at https://www.codepublishing.com/WA/Renton.
Project Proposal: The project site is located at 12 Seahawks Way (APN 2924059015), totals
approximately 728,627 square feet (16.73 acres) in area, and is zoned Commercial Office
Residential (COR) and is located within Urban Design District C . The applicant is proposing
two additions to the existing VMAC facility (one on the east side of the existing building and
one on the west side) and the construction of a new 1,600 square foot ground floor hospitality
suite at the southwest corner of the VMAC. The east addition would include an expansion of
floors 1-4 with a height of sixty-five feet (65’). Floors 1-3 would add 12,000 square feet each
and floor 4 would include add 15,000 square feet, resulting in a total new area of 51,000
square feet. The addition on the west side of the building would be limited to an expansion of
floor 3 and would increase the building height at this location to fifty feet (50’) and would total
21,600 square feet. According to the City’s COR Mapping system, the site is mapped with
regulated slopes, a piped Type F stream, is within a high seismic hazard area and is located
within the 200-foot shoreline jurisdiction of Lake Washington. The site is mapped within the
Shoreline High Intensity Designation of Lake Washington Reach C.
Current Use: The property is currently developed with the Seahawks VMAC facility, which
includes an existing 251,800 square foot main building, a 5,000 square foot maintenance
shed, and outdoor football training fields.

1. Zoning Districts and Land Use Designation: The subject property is located within the
Commercial Office Residential (COR) comprehensive plan land use and zoning
designations and is also located within Urban Design District C. The purpose of the
Commercial Office Residential Zone (COR) is to provide for a mix of intensive office,
hotel, convention center, and residential activity in a high -quality, master-planned
development that is integrated with the natural environment. Comme rcial retail and
service uses that are architecturally and functionally integrated are permitted. Also,
commercial uses that provide high economic value may be allowed if designed with the
scale and intensity envisioned for the COR Zone. The scale and location of these sites
will typically denote a gateway into the City and should be designed accordingly.
The west portion of the project site is also located within the Shoreline High Intensity
Designation. Within this designation, land uses allowed in the underlying zoning in
RMC 4-2-060 are allowed in this overlay district, subject to the preference for water -
oriented uses. Land uses in the underlying zoning that require an administrative (AD) or
Hearing Examiner (H) conditional use permit in the underlying zoning require the
corresponding Shoreline Conditional Use Permit.
The project site includes existing office uses, existing indoor recreational facilities, and
existing outdoor recreational facilities. The proposal would include additions on the east
and west sides of the building, as well as the addition of a new ground floor hospitality
suite. The proposal would include expansions of the existing office and indoor
recreational uses. Office uses are outright permitted uses within the COR zone.
Recreational facilities, indoor, existing are permitted uses within the COR zone,
provided, the use shall be housed in a structure containing one or more of the
following uses: offices, residences, hotels, convention centers, and/or research
and development facilities.
2. Development Standards: The project would be subject to RMC 4-2-120B,
“Development Standards for Commercial Zoning Designations” effective at the time of
complete application (noted as “COR standards” herein). These standards are available
on the City’s website at
https://www.codepublishing.com/WA/Renton/#!/Renton04/Renton0402/Renton04021
20B.html#4-2-120B.
Minimum Lot Size, Width and Depth – There are no minimum lot size, width, or depth
requirements within the COR zone. No changes are proposed to the existing lot
dimensions. The existing lot has a total area of 728,627 square feet with a width of
approximately 896 feet and a depth of approximately 675 feet.
Setbacks – Setbacks are the distance between the building and the property line or any
private access easement or tract. Setback requirements in the COR zone are determined
through the site plan review process.
Within the 200-foot shoreline jurisdiction of Lake Washington, lots within the Shoreline
High Intensity Environment Designation (RMC 4-3-090D.7.a) are required to provide a
100-foot vegetation conservation buffer as measured from the ordinary high water mark
(OHWM) of Lake Washington.
The proposed east addition would maintain a front setback of approximately 48 feet. The
proposed west addition and hospitality suite would be located outside of the 100-foot
VMAC Expansion Study
Page 3 of 8
June 26, 2025
vegetation conservation buffer required from Lake Washington. The front, side, and rear
yard setback requirements for the proposed additions would be determined at the
time of site plan review. The proposed additions on the west side of the building
appear to comply with the shoreline setback requirements as established by the
Shoreline Master Program (RMC 4-3-090).
Gross Floor Area – There are no requirements for gross floor area.
Building Height – Maximum building height in the COR zone is 10 stories and/or 125 feet.
Buildings or portions of buildings that exceed fifty feet (50') in height shall include upper
story setbacks as follows: The minimum setback for a fifth story and succeeding stories
shall be ten feet (10') minimum from the preceding story, applicable to each story or an
equivalent standard that adds interest and quality to the building. In no case shall
building height exceed the maximum allowed by the Airport Compatible Land Use
Restrictions, for uses located within the Federal Aviation Administration Airport Zones
designated under RMC 4-3-020.
Within the 200-foot shoreline jurisdiction of Lake Washington, buildings landward of one
hundred feet (100') from the OHWM, the maximum building height shall be defined by a
maximum allowable building height envelope that shall:
i. Begin along a line lying parallel to and one hundred feet (100') from OHWM at a height
of either thirty five feet (35') or one-half (1/2) the maximum height allowed in the
underlying zone, whichever is greater; and
ii. Have an upward, landward transition at a slope of one vertical to one horizontal from
the beginning height either (a) until the line at which the maximum height allowed in the
underlying zoning in chapter 4-2 RMC is reached (from which line the height envelope
shall extend landward at the maximum height allowed in the underlying zoning), or (b) to
the end of shoreline jurisdiction, whichever comes first.
Building elevations were not included with the submitted pre-application materials,
therefore staff was unable to verify compliance with the building height
requirements. It is the applicant’s responsibility to demonstrate compliance with
building height requirements and FAR Part 77 at the time of formal land use
application.
Roofline and Façade Modulation – Buildings shall provide vertical and horizontal
modulation of roof lines and facades of not less than two feet (2') at a minimum interval
of forty feet (40') per building face, or an equivalent standard that adds interest and
quality to the building. It is the applicant’s responsibility to demonstrate compliance
with the roofline and façade modulation requirements at the time of formal land use
application.
Maximum Lot Coverage for Buildings – The COR zone allows a maximum building
coverage of 65 percent, or 75 percent if parking is provided within a building or within an
on-site parking garage. As stated on the submitted site plan, the applicant estimates that
the building coverage after the construction of the proposed additions would be 42.5
percent of the lot area, which is less than the maximum lot coverage permitted for the
COR zone. It is the applicant’s responsibility to demonstrate compliance with
building coverage requirements at the time of formal application.

(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 th ousand (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 shall be provided for recycling and refuse deposit areas.
Compliance with the refuse and recycling standards would be reviewed at the time
of formal land use application.
4. Landscaping: Except for critical areas, all portions of the development area not covered
by structures, required parking, access, circulation or service areas, must be landscaped
with native, drought-resistant vegetative cover. Building additions that do not increase
the gross square footage of the building area by more than one -third (1/3) are not
subject to compliance with the landscape regulations.
5. Significant Tree Retention: Application materials identify that there are mature trees on
the site. When significant trees (greater than 6-inch caliper or 8-caliper inches for alders
and cottonwoods) are proposed to be removed, a tree inventory and a tree retention plan
along with an arborist report, tree retention plan and tree retention worksheet shall be
provided with the formal land use application as defined in RMC 4-8-120. The tree
retention plan must show preservation of at least 30% of significant trees. Please refer to
RMC 4-4-130, Tree Retention and Land Clearing Regulations for further general and
specific tree retention and land clearing requirements.
In addition to retaining a minimum of 30% of existing significant trees, each new lot would
be required to provide a minimum tree density of 30 tree credits per net acre. Tree credits
encourage retention of existing significant trees with larger trees being worth more tree
credits.
