NOTE: The applicant is cautioned that information contained in this summary is preliminary and non-binding and
may be subject to modification and/or concurrence by official City decision-makers. 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.
I have completed a preliminary review for the above-referenced proposal located at parcel(s) 1923059023 and
1923059001. The following comments are based on the pre-application submittal made to the City of Renton by
the applicant.
WATER
The proposed redevelopment project is within the City of Renton’s water service area and in the 196-pressure
zone and it is located within the 5 and 10-year capture zones (Zone 2) of the City’s wellhead protection areas. The
comments below represent a scenario where the future lots would be built out with a mixture between
residential and commercial units. The binding site plan application will be limited to frontage improvements
and stormwater controls and any elected utility stubs or improvements within the site.
Existing Water Mains:
• There are existing 10-inch and 12-inch city-owned water mains within utility easements that are located
along the north side of the existing Triton Tower 3. Please refer to city water project plan no. W-1829 for
the location and sizes of the water mains within the properties. The maximum capacity of the existing on-
site 12-inch water main is 3,200 gallons per minutes (gpm) and 2,400 gpm for the 8-inch main.
• There is an existing 24-inch water main in Talbot Rd S that can deliver 12,000 gpm. Please refer to city
water project plans no. W-0820.
• There is an existing 12-inch water main in S Renton Village Pl that can deliver 4,200 gpm. Please refer to
city water plans no. W-0556.
• The static water pressure from the above water mains is approximately 68 psi at ground elevation of 39
feet. There are existing water meters to the existing buildings on the site including:
Existing Water Services:
• 707 S Grady Way (Tower 3):
o There is an existing 4-inch domestic water meter located in a concrete vault, north of the building
(MTR-015864).
o There is an existing 2-inch irrigation water meter located in a concrete vault, north of the building
(MTR-015927).
o There is an existing 6-inch fire service meter located in a concrete vault, north of the building
(MTR-015897).
• 700 S Renton Village Place (Tower 2):
o There is an existing 4-inch domestic water meter located in a concrete vault, south of the building
(MTR-015797).
o There is an existing 2-inch irrigation water meter located in a concrete vault, south of the building
(MTR-016012).
o There is an existing 6-inch fire service meter located in a concrete vault, south of the building
(MTR-005088).
Based on the review of project information submitted for the pre-application meeting, Renton Regional Fire
Authority has determined that the preliminary fire flow demand for the proposed development is 3,750 gpm,
including the use of an approved fire sprinkler system. Per City Codes, a looped water main is required around all
buildings with a fire flow demand above 2,500 gpm. The following developer installed water main improvements
will be required to provide domestic and fire protection service to the development including but not limited to:
1. Replacement of the 330-ft section of 10-inch water main along the north side of Tower 3 with a new 12-
inch water extending to the west property line.
2. Installation of a new 12-inch water main (approximately 850 feet) along the west property line connecting
the above new 12-inch water main to the existing 12-inch water main in S Renton Village Place. The
water line shall be installed within a 15-ft wide easement to be conveyed to the city. See attached water
sketch for reference only.
a. Please note that the existing 8-inch water main on the west side of the property is located within
the adjacent parcel and it may be abandoned or relocated in the future if the property is
redeveloped. As such, to meet the looped water main requirement, a new 12-inch water line will
be required along the west side of the proposed development and it shall be located in a new 15-
ft wide easement within the subject property. The suggestion regarding the replacement of this 6-
inch line with a new and permanent 12-inch line to meet the fire flow requirement for the Triton
development cannot be enforced if Renton Village chooses to redevelop its property and requests
that the line be relocated somewhere else within its property. If Triton Development can secure a
permanent easement from Renton Village for the replacement of this water line to provide fire
protection to their development, then the city will consider this alternative.
3. Minimum 10-inch diameter water mains must be installed in the internal streets to provide fire flow for
each building, and fire hydrant coverage. See attached sketch for reference.
4. Installation of a fire sprinkler stub a with a detector double check valve assembly (DDCVA) for backflow
prevention to each building. The fire sprinkler stub and related piping shall be done by a registered fire
sprinkler designer/contractor. The DDCVA shall be installed on the private property in an outside
underground vault per City standard plan no. 360.2. The DDCVA may be installed inside the building if it
meets the conditions as shown on City’s standard plan 360.5 for the installation of a DDCVA inside a
building. The location of the DDCVA inside the building must be pre-approved by the City Plan Reviewer
and Water Utility.
5. Installation of additional fire hydrants around the building as required by the Fire Authority.
6. A hydrant is required within 50 feet of the building’s fire sprinkler system fire department connection
(FDC).
7. Installation of a separate water service and meter for the residential portion of each new building. The
sizing of the meter shall be in accordance with the most recent edition of the Uniform Plumbing Code.

behind on the meter on private property per City Standards. The DCVA may be located inside the
building if the location is approved by the City Plan Reviewer and City Water Utility Department.
8. Installation of a separate water meter for the commercial portion of each new building. The sizing of the
meter shall be in accordance with the most recent edition of the Uniform Plumbing Code.
a. All commercial domestic water meters shall have a reduced pressure backflow assembly (RPBA)
installed behind the meter on private property per City Standards. The RPBA shall be installed
inside an above ground heated enclosure per City Standard Plan 350.2. The RPBA may be located
inside the building if a drainage outlet for the relief valve is provided and the location is approved
by the City Plan Reviewer and City Water Utility Department.
9. Domestic water meters size 3-inch or larger shall be installed in an exterior vault per City Standard Plan
320.4. The meter vault shall be located within public right-of-way or within an easement on private
property.
10. Installation of a separate water meter for landscape irrigation.
a. A DCVA per City Standard Plan 340.8 is required downstream of the irrigation meter. DCVAs size 2-
inch or smaller shall be installed a meter box and DCVAs size 3-inch or larger shall be installed in an

FROM: Alex Morganroth, Principal Planner
SUBJECT: Triton Tower Binding Site Plan
700 and 707 Talbot Rd S (APNs 1923059001 & 1923059023) – AKA Triton
Towers 2 and 3
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, 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
www.rentonwa.gov.
Project Proposal: The subject site is comprised of two (2) properties at 700 and 707 Talbot Rd S (APNs 1923059001
and 1923059023) at the SW corner of the intersection of S Grady Way and Talbot Road S. The two (2) parcels total
597,771 sq. ft. (13.72 acres) and are zoned Commercial Office (CO) with an Urban Design District D overlay. The
current site is currently developed two (2) existing seven level office structures totaling 270,395 sq. ft. (Triton
Towers 2 and 3) and the associated surface parking. The applicant proposes a binding site plan in order to create
two (2) additional lots for a total of four (4) lots comprising the site. The four (4) proposed lots would be
approximately 149,105 sq. ft. (Lot 1), 122,859 sq. ft. (Lot 2), 170,131 sq. ft. (Lot 3), and 155,507 sq. ft. (Lot 4).
According to the applicant, the purpose of the binding site plan is to separate the parking lot areas from the existing
buildings in order to facilitate future redevelopment of the site. Access to the site is proposed to remain via two (2)
driveways off of S Grady Way and two (2) driveways off of Talbot Rd S. The City of Renton (COR) Maps indicates the
presence of a High Seismic Hazard and the Downtown Wellhead Protection Area Zone 2.
Current Use: The property is currently developed with two (2) existing seven (7) story office structures totaling
270,395 sq. ft. of floor area and the associated surface parking.
1. Zoning and Overlay Districts: The subject property is located within the Commercial Mixed use land use
designation and Commercial Office (CO) zoning classification. The property is also within the Urban Design
District D. No new uses are proposed as a part of the proposal.
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 “CO standards”
herein). These standards are available on the City’s website at
http://www.codepublishing.com/WA/Renton/#!/renton04/Renton0402/Renton0402120B.html#4-2-
120B.
Density – minimum of 75 dwelling units per net acre (du/ac) if within a mixed use building and a maximum
of 150 du/ac. According to the applicant’s calculations, a net density of approximately 99 du/ac is proposed.
Density may be increased up to 250 dwelling units per net acre subject to conditional use permit approval.
The applicant would be required to demonstrate compliance with the density range of the CO zone using
net density calculations and a Density Worksheet would need to be submitted with the land use
application. Density cannot be modified via the PUD process.
Minimum Lot Size, Width and Depth – The minimum lot size in the CO zone is 25,000 square feet for lots
created after July 11, 1993. There are no minimum requirements for lot width or depth within the CO zone.
The existing lot sizes exceed 25,000 sq. ft. The applicant would be required to maintain a minimum 25,000
sf lot size as part of the redevelopment and subdivision of the site.
Building Coverage – The CO zone allows a maximum building coverage of 65 percent, or 75 percent if
parking is provided within a building or within a parking garage. The applicant is proposing to utilize both
existing surface and new structured parking. The applicant indicated a building coverage of approximately
60% in the preapplication submittal documents. Compliance with the building coverage requirements
would be verified at the time of formal land use application review.
Building Setbacks – Setbacks are the distance between the building and the property line or any private
access easement or tract. Setback requirements in the CO zone are as follows: 0-30 feet minimum front
yard (depending on the building height), and 0-30 feet minimum secondary front yard (depending on
building height). There is no maximum front yard setback requirement for non-residential buildings; and no
rear or side yard setbacks unless the property abuts a residential zoned property, where the setback along
residentially zoned properties is 15 feet. The proposal does not abut residentially zoned property. The
submitted materials identify the approximate locations of the proposed building and structure, but no
setback measurements were indicated.
Gross Floor Area – There is no minimum requirement for gross floor area.
Maximum Gross Floor Area of Any Residential Use on a Site – Limited to 25% of the total gross floor area
of all buildings on site.
Building Height – Maximum building height in the CO zone is 250 feet. 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. The applicant indicated a maximum
new building height of 90 feet. The existing buildings are approximately 150 feet tall. Therefore the
proposal would comply with the minimum height standard of the CO zone.
The subject site is located within the Airport influence area. Height is restricted in this area by the FAR
Part 77 surface area, as such the applicant shall verify at time of land use application and building permit
that the height of the proposed structure does not penetrate the FAR Part 77 surface area. In addition,
the applicant shall be required to submit a draft avigation easement with the land use application per
RMC 4-3-020E.
Roofline and Facade Modulation - Residential mixed use buildings: 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.
Pedestrian Access – A pedestrian connection shall be provided from a public entrance to the street, unless
the Reviewing Official determines that the requirement would unduly endanger the pedestrian.
Screening – Screening must be provided for all surface-mounted and roof top utility and mechanical
equipment. If applicable, the application would need to include elevations and details for the proposed
