SUBJECT: Topgolf Phase II
780 Logan Ave N
LUA22-000291
I have reviewed the application for the Topgolf Phase II project located at 780 Logan Ave N and have the
following comments:
EXISTING CONDITIONS
The site is comprised of existing parcel 0886610010, is approximately 596,013 square feet in size and is
rectangular in shape. The site currently contains a newly constructed premier golf entertainment complex
with up to 508 surface parking stalls as part of the phase 1 development associated with the Master Plan
approval. The site is fronted by Logan Ave N to the west, N 8th St to the north, Park Ave N to the east and
private property to the south.
WATER: The proposed development is within the City’s water service area and in the Kennydale 308
Pressure Zone and in the Downtown 196 Pressure Zone. There is an existing 12-inch water main
(308 pressure zone) located in N 8th St that can deliver a maximum flow capacity of 4,800 GPM
(see water plan no. W-31490E). There is an existing 16-inch water main (196 pressure zone)
located in Park Ave N that can deliver a maximum flow capacity of 8,600 GPM (see water plan
no. W-19220A). There is an existing 12-inch water main (308 pressure zone) located on the
parcel within an easement that can deliver a maximum flow capacity of 4,800 GPM (no record
drawings available, see active construction permit C20000631).
SEWER: The proposed development is within the City’s sewer service area. There is an existing private 8-
inch gravity wastewater main on the parcel with a 6-inch stub to the building pad (no record
drawing available, see active construction permit C20000631).
STORM: There is an existing 8-inch and 12-inch private stormwater stub to the building pad (no record
drawing available, see active construction permit C20000631). The storm stubs drain to an
existing biopod that was sized assuming 100% pollution generating impervious surface in the
phase II area where the proposed project is located.
STREETS: The proposed development fronts Logan Ave N to the west,

WATER
1. Civil plans for the water main improvements are required and must be prepared by a professional
engineer registered in the State of Washington. Refer to City of Renton General Design and
Construction Standards for Water Main Extensions as shown in Appendix K of the City’s 2019
Water System Plan. Adequate horizontal and vertical separations between the new water main
and other utilities (storm sewer pipes and vaults, sanitary sewer, power, gas, electrical) shall be
provided for the operation and maintenance of the water main. Retaining walls, rockeries or
similar structures cannot be installed over the water main unless the water main is installed inside
a steel casing.
2. There are multiple existing fire hydrants within 300 feet of the property along N 8th St, Park Ave
N and within an easement on the parcel.
3. Based on the review of project information submitted, Renton Regional Fire Authority has
determined that the fire flow demand for the proposed development is 2,000 GPM.
4. The proposed conceptual plan depicts an extension of the 12-inch water main (308 zone) through
the site connecting to the existing 16-inch water main (196 zone) in Park Ave N with a three valve
cluster. The proposed concept is acceptable.
a. At the valve cluster in Park Ave N, the 308 pressure zone valve on the 12-inch main is to
be normally closed.
b. Public water mains on private property require a 15-foot public easement centered over
the pipe and the building must be set back 10 feet from the water main.
5. Installation of a fire sprinkler stub a with a detector double check valve assembly (DDCVA) is
required for backflow prevention to the building. The sizing of 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 360.2.
The DDCVA may be installed inside the building if it meets the conditions per City 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.
a. The proposed conceptual plan depicts a DDCVA in an outside underground vault which
is acceptable.
6. Installation of off-site and on-site 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. A hydrant is
required within 50 feet of the building’s fire sprinkler system fire department connection (FDC).
a. The proposed conceptual plan depicts the FDC within 50 feet of a new fire hydrant which
is acceptable.
7. Installation of a separate water meter for the commercial portion of the new building. 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 pre-
approved by the City Plan Reviewer and City Water Utility Department. The backflow prevention
assembly must be located adjacent to and behind a building exterior wall.
a. The proposal depicts a 2-inch commercial water service and meter with an RPBA
backflow which is acceptable. Meters and backflow prevention shall be installed in
accordance with City standard plans. The water service for the meter should be taken

STORM DRAINAGE
1. A geotechnical report dated October 29, 2019, completed by GeoEngineers, was provided with
the Land Use Application. The report discusses the soil and groundwater characteristics of the site
and provides recommendations for project design and construction. The report does not support
the use of infiltration due to low permeability soils and shallow groundwater table starting at 4
feet below ground surface.
2. Navix, with the Land Use Application, submitted a Preliminary Drainage Plan and Technical
Information Report (TIR), dated July 26, 2022. Based on the City of Renton’s flow control map, the
site falls within the Peak Rate Flow Control Standard Area matching Existing Site Conditions and
is within the East Lake Washington Drainage Basin. The report is based on a Full drainage review
and the nine Core Requirements and the six Special Requirements have been discussed in the
Technical Information Report.
a. General: The following general comments shall be addressed as part of the Civil
Construction Permit Application:
b. General: The preliminary TIR refers to the TIR approved as part of the phase 1
construction under civil construction permit C20000631 in multiple areas. The previously
approved TIR was designed in accordance with the 2017 RSWDM, however, the 2022
RSWDM is current and must be followed. Where the applicant indicates that the
proposed design is consistent with prior assumptions made in the C20000631 TIR,
additional confirmation and analysis is included in the proposed projects TIR to indicate
that the 2017 RSWDM is consistent with the 2022 RSWDM for the subject section.
c. Offsite Analysis, RSWDM Core Requirement #2: All proposed projects must submit an
offsite analysis report that assesses potential offsite drainage and water quality impacts
associated with development of the project site and the initial permit submittal shall
include, at minimum, a Level 1 Downstream Analysis. A level 1 downstream analysis has
been included.
i. The downstream analysis refers to the downstream analysis performed as part
of phase I and includes the TIR approved as part of C2000631. Staff concurs that
the prior downstream analysis is acceptable for use.
d. Flow Control, RSWDM Core Requirement #3: Any proposed detention and/or water
quality vault shall be designed in accordance with the RSWDM that is current at the time
of civil construction permit application. The project is claiming to be exempt due to less
than a 0.15 CFS increase.
i. The report refers to the TIR approved as part of C20000631 which accepted a
flow control exemption for a 0.15 CFS exemption. Given that the proposed
project area was included in the prior analysis and the proposed project land
use does not differ from the prior assumptions, staff concurs that the exemption
is acceptable.
e. Conveyance, RSWDM Core Requirement #4: All new conveyance systems constructed as
part of the project must be sized to meet RSWDM standards for the total tributary area
(onsite and offsite) that the storm systems serve. The proposal depicts runoff being
routed to the existing site catch basins and building drains being connected to the existing
storm stub. A conveyance capacity analysis is included showing that the stubs have
sufficient capacity to convey the new runoff.
i. The report refers to the TIR approved as part of C20000631 in which the
conveyance system for the east basin of the site was designed assuming a 100%

November 3, 2022
impervious area for the phase II construction. The report indicates that further
conveyance capacity analysis is not needed as the proposal does not exceed the
original design parameters. Staff concurs with the assessment.
f. Construction Stormwater Pollution Prevention, Core Requirement #5: The proposal does
not include a CSWPP and ESC plan. The preliminary TIR includes a CSWPP and indicates
that an ESC plan will be developed.
i. A final CSWPP and ESC plan shall be included with the TIR and utility plans
submit as part of the civil construction permit.
g. Maintenance and Operations, Core Requirement #6: The proposal does not include a
maintenance and operations manual. The preliminary TIR includes a maintenance and
operation manual.
h. Financial Guarantees and Liability, RSWDM Core Requirement #7: All drainage facilities
constructed or modified for projects must comply with the financial guarantee
requirements and the liability requirements of the City. The preliminary TIR indicates that
a bond quantity worksheet and all required documents will be provided at a future date.
i. A bond quantity worksheet shall be included with the TIR as part of the civil
construction permit. Financial guarantees and liability requirements shall be
met prior to civil construction permit issuance.
i. Water Quality, RSWDM Core Requirement #8: All projects that add more than 5,000
square feet of pollution generating impervious surface (PGIS) that is not fully dispersed
and less than 0.75 acre of pollution generating pervious surface that is not fully dispersed
require water quality. The preliminary TIR indicates that the existing BioPod water quality
facility meets the requirement.
i. The report refers to the TIR approved as part of C20000631 in which the east
basin water quality facility was designed assuming the future phase II area to
be 100% impervious surface. The report indicates that further water quality
measures are not needed as the proposed land use is consistent with that
assumed in the design of the existing water quality facility. Staff concurs with
the assessment.
j. Onsite BMPs, RSWDM Core Requirement #9: Appropriate on-site BMPs will be required
to help mitigate the new runoff created by this development. The preliminary TIR
provides an analysis of the large lot BMP’s concluding that none are feasible.
i. Staff concurs with the assessment which is consistent with the analysis
conducted in the TIR approved as part of C20000631.
2. The development is subject to a surface water system development charge (SDC) fees. Fees will
be charged based on the rate at the time of construction permit issuance.
a. The 2022 SDC fee is $0.84 per square foot of new impervious surface but not less than
$2,100.
TRANSPORTATION/STREET COMMENTS
1. Sites that generate 20 or more net new peak hour trips (either in the AM peak or PM peak) are
required to do a traffic impact analysis. The trips should be calculated based on the guidelines of
the current ITE Trip Generation Manual. Refer to the attached policy guidelines for traffic impact
analysis for guidelines. If the site generates 20 or more new peak hour trips in either AM peak or
DocuSign Envelope ID: 9D2BB334-50A7-4DEB-B080-28705A1188AE
Topgolf Phase II– LUA22-000291
Page 6 of 7
November 3, 2022
PM peak, then applicant should contact the City to get information of the locations where traffic
analysis is required.
a. A TIA dated October 2022 was prepared by TranspoGroup and submit with the land use
application. The TIA discussed traffic impacts at a horizon year of 2031. The report
evaluates the Level Of Service (LOS) at two subject intersections, N 8th St/Park Avenue
N and N 6th St/Park Avenue N. Further the report considers additional internal trips from
the Phase 1 TopGolf site and their utilization of the proposed site access point. The level
of service at the subject intersections was found to operate at a LOS C without the
project at the horizon year and with the project the intersections were found to operate
at a LOS C. The TIA concludes that the LOS is within the City’s published standard and
mitigation measures, other than payment of transportation impact fees, are not
required.
b. At the request of City staff, left turning movements from Park Ave N are allowed into
the site while a left turn out of the site onto Park Ave N is not allowed. In order to
accommodate a left turning movement into the site, a portion of the existing
landscaped median must be removed. The TIA analyzes intersections according to the
requested access and the conceptual siteplan shows the modifications to Park Ave N
that facilitate a left turn lane; however, the siteplan does not depict channelization that
would restrict a left turning movement out of the site. Applicant shall provide
channelization to restrict the turning movement on the site plan submit with the civil
construction permit.
c. Additionally, the TIA discusses that the 95% que analysis at the site access is not
anticipated to exceed one vehicle. The proposed median modifications to construct a
left turn lane provide a 50-foot que length and 80-foot taper which is sufficient to allow
queuing of at least two vehicles. The que analysis is not included in the report, however,
staff concurs with the assessment and que length proposed.
d. The TIA analysis assumes the installation of a 114 unit hotel, however, this is not
depicted in the proposed site plan. Given that the LOS impact does not result in further
mitigation it is ok to include, however, future development of the hotel area will likely
require a separate TIA.
2. Frontage improvements are required for all new construction with valuation in excess of
$175,000. The proposed development fronts N 8th St to the North, Park Ave N to the East, Logan
Ave N to the west and private property to the south.
a. A modification was submit and approved as part of LUA18-000094 for the master site
plan and phase 1 construction. The modification approved retaining the existing street
frontage along the entire parcel provided the required dedication is provided in addition
to conditions such as replacing broken elements and raising the landscape strip to be
flush with the sidewalk. Dedication and compliance with the conditions of approval is
being completed under the active civil construction permit C20000631.
3. Street lighting improvements are required for projects consisting of more than four (4) residential
units. See RMC 4-6-060 for street lighting requirements.
a. The street modifications as noted above retained the existing improvements therefore
compliance with the street lighting standard is not required.
4. Refer to City code 4-4-080 regarding driveway regulations.
a. A minimum separation of 5 feet is required between driveway and the property line.
b. Maximum driveway slopes shall not exceed 15%. Driveways exceeding 8% shall provide
slotted drains.

c. The width of any driveway shall not exceed 30 feet exclusive of the radii of the returns or
the taper section.
d. There shall be no more than one driveway for each 165 feet of street frontage.
5. Per RMC 4-6-060 site access shall be a minimum of 125 feet from an intersection.
a. The proposed site access is more than 125 feet which is acceptable.
5. Undergrounding of all existing and proposed utilities is required on all frontages per RMC 4-6-090.
6. Paving and trench restoration within the City of Renton right of way shall comply with the City’s
Restoration and Overlay requirements.
7. The development is subject to transportation impact fees. Fees will be charged based on the rate
at the time of building permit issuance.
a. Unless otherwise noted on the fee schedule, the 2022 transportation impact fee is
$7,145.85 per net new PM peak hour person vehicle trip.
