9. Based on the review of project information submitted for the pre-application meeting, Renton
Regional Fire Authority determined the preliminary fire flow is 2,500 GPM. 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.
10. 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 development including but not limited to the items that follow.
• The proposed building resides over the existing water main along the northely portion of the
property. The existing water main shall either be relocated such that it is a minimum 10 feet
outside of the building footprint, or, the developer may abandon and remove that portion of
the water main, including hydrants. If electing to abandon the existing water main, the
developer shall retain the loop around the 1300 SW 16th St building by providing a 12-inch
water main extension from SW 16th St north to the existing main. A partial release of
easement and a new easement would be required.
• The existing 4-inch water service shall be removed and the valve within SW 16th St shall be
plugged.
• All removed equipment (hydrants, meters, etc.) shall be returned to the City.
• A 15 feet wide public water easement is required for any public water main, hydrants and
water meters located outside City right-of-way. A minimum 10-foot setback is required from
the building foundation to the new water main.
• Installation of a fire sprinkler stub a with a double check detector assembly (DCDA) 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 DCDA
shall be installed on the private property in an outside underground vault per City Standard
Plan 360.2. The DCDA may be installed inside the building if it meets the conditions per City
Standard Plan 360.5 for the installation of a DCDA inside a building. The location of the
DCDA inside the building must be pre-approved by the City Plan Reviewer and Water Utility.
The backflow prevention assembly must be located adjacent to and behind a building
exterior wall.
• 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

FROM: Jill Ding, Senior Planner
SUBJECT: Longacres North Parking Garage – 1300 and 1302 SW 16th St,
Renton, WA 98055 (Parcel Nos. 2423059071, 2423049055,
2423049052, and 2423049050)
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 proposed project site (“Site”) consists of four (4) separate parcels (parcel
nos. 2423059071, 2423049055, 2423049052, and 2423049050) located at 1300 and 1302 SW
16th St. Based on King County Department of Assessments, the Site area totals approximately
72,435 square feet (1.66 acres). The Site is part of the original 158 acres of property known as
the Longacres Office Park (“LOP”) and is located in the Medium Industrial (IM) zone. The
proposed project would include a lot combination for the construction of a 325,000 square foot,
5-6 story parking garage with approximately 1,000 parking spaces. The two existing curb cuts off
of SW 16th St would provide access to the proposed parking garage. The site is currently
developed with an electric utility building for the larger LOP, a network utility building proposed
for removal, and a surface parking lot. According to City of Renton (COR) Maps, the Site contains
high seismic hazard areas and special flood hazard areas (100 year flood) FEMA Zone – AE.
Springbrook Creek is located approximately 300 feet to the east of the project site.
Current Use: The site is currently developed with an electric utility building for the larger LOP, a
network utility building proposed for removal, and a surface parking lot.
Comprehensive Plan/Zoning Requirements: The property is located within the Employment
Area (EA) land use designation and Medium Industrial (IM) zoning classification. The purpose of
the Medium Industrial Zone (IM) is to provide areas for medium-intensity industrial activities
involving manufacturing, processing, assembly, and warehousing. Uses in this zone may require
some outdoor storage and may create some external emissions of noise, odor, glare, vibration,
Longacres North Parking Garage

etc., but these are largely contained on site. Compatible uses that directly serve the needs of
other uses permitted within the district are also allowed zone-wide. Parking garages are an
outright permitted use within the IM zone.
Development Standards: The project would be subject to RMC 4-2-130A, “Development
Standards for Industrial Zoning Designations” effective at the time of complete application
(noted as “IM standards” herein). These standards are available on the City’s website. Please
refer to the applicable footnotes in the RMC when applying these development standards to
your proposal.
Minimum Lot Size, Width and Depth: The minimum lot size in the IM zone is 35,000 square feet
for lots created after September 1, 1985. There are no minimum requirements for lot width or
depth for lots created after September 1, 1985 within the IM zone. After the completion of a lot
combination, the project site would have a minimum lot size of 72,435 square feet, which
would comply with the minimum lot size requirement of the IM zone.
Building Coverage: There is no maximum building coverage requirement in the IM zone.
Building Setbacks: Setbacks are the distance between the building and the property line or any
private access easement or tract. A front yard setback of 15 feet is required from SW 16th St, a
10-foot landscaped freeway frontage setback would be required from I-405. There is 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. Setback dimensions were not included with the submitted pre-application materials,
therefore staff was unable to verify compliance with this requirement. The Lot Combination
would need to be recorded prior to TCO to ensure compliance with sideyard setbacks.
Structures may be built up to the side property lines, but cannot cross over. Compliance with
building setback requirements would be verified at the time of formal land use application
review.
Building Height: There is no maximum building height in the IM zone. 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 proposed parking garage would have 5-6 stories and a maximum height of 45-55
feet. The subject site is located within the Federal Aviation Regulations (FAR) Part 77, Objects
Affecting Navigable Airspace of the Renton Municipal Airport. 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 any proposed structure(s) would not
penetrate the FAR Part 77 surface area.
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 methods of screening. No mechanical or utility equipment was
identified in the submitted materials. See RMC 4-4-095, Screening and Storage
Height/Location Limitations for specific requirements.
Refuse and Recycling Areas: There are no refuse and recycling requirements applicable to stand
alone parking garages.
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. Any landscaping area shall be a minimum of five feet

(5’) in width. An underground sprinkling system shall be required to be installed and maintained
for all landscaped areas. A conceptual landscape plan would be required at the time of formal
land use application.
Street Trees and Planter Landscaping: Minimum planting strip widths between the curb and
sidewalk are established according to the street development standards of RMC 4-6-060. Street
trees and, at a minimum, groundcover shall be planted within planting strips. Please see RMC 4-
4-070.L.2 for additional planter strip ground cover standards.
Street Frontage Landscaping: The minimum onsite landscape width required along street
frontages is 10 feet, with the exception of areas for required walkways and driveways, and shall
contain trees, shrubs, and landscaping. Compliance with street frontage landscaping would be
verified at the time of formal land use application review.
Parking: The proposed parking garage would be a stand alone structure, providing off-site
parking for nearby proposed office and manufacturing uses. There are no minimum parking
requirements for stand alone parking garages. The proposed parking garage would provide
approximately 1,000 spaces.
It should be noted that the parking regulations specify standard stall dimensions. Structured
parking stalls must be a minimum of 8 feet, 4 inches (8’4”) in width and fifteen feet (15’) in
length, compact stall must be seven feet, six inches (7'6") in width and a minimum of twelve feet
(12') in length; compact surface parking spaces shall not account for more than 50 percent of all
onsite uses.
ADA accessible stalls must be a minimum of 8 feet in width by 20 feet in length, with an adjacent
access aisle of 8 feet in width for van accessible spaces. The minimum required number of
accessible spaces is two percent (2%) of the total spaces when total required parking is between
501 and 1,000 parking spaces. For lots over 1,000 spaces, the minimum number of accessible
spaces is 20 plus 1 space for every 100 spaces, or fraction thereof, over 1,000.
Bicycle parking shall be provided for all residential developments that exceed five (5) residential
units and/or all non-residential developments that exceed four thousand (4,000) gross square
feet in size.
Bicycle parking shall be provided for all non-residential developments that exceed four thousand
(4,000) gross square feet in size. When there are two (2) or more separate uses on a site, the
required bicycle parking for the site shall be the sum of the required parking for the individual
uses. The number of bicycle parking spaces shall be equal to ten percent (10%) of the number of
required off-street vehicle parking spaces for all uses except attached dwellings. Attached
dwellings shall provide one-half (0.5) bicycle parking space per one dwelling unit. Bicycle
parking is not required for stand alone parking garages.
Fences/Walls: The location must be designated on the landscape plan or grading plan. A fence
and/or wall detail should also be included on the plan. A retaining wall that is 4 feet or taller, as
measured by the vertical distance from the bottom of the footing to the finish grade at the top
of the wall requires a building permit. A fence shall not be constructed on top of a retaining wall
unless the total combined height of the retaining wall and the fence does not exceed the
allowed height of a standalone fence. A fence taller than seven feet (7') shall require a building
permit (six feet (6’) per building code) or a written exemption from the Building Official. The
maximum height of an industrial fence is eight feet (8') anywhere on the lot provided the fence
does not stand in or in front of any required landscaping or pose a traffic vision hazard. A

(18") caliper; and trees that shelter interior trees or trees on abutting properties from strong
winds, which could otherwise allow such sheltered trees to be blown down if removed.
Priority Two: Healthy tree groupings whose associated undergrowth can be preserved; other
significant native evergreen or deciduous trees; and other significant non-native trees.
Priority Three: Alders and cottonwoods shall be retained when all other trees have been
evaluated for retention and are not able to be retained, unless the alders and/ or cottonwoods
are used as part of an approved enhancement project within a critical area or its buffer.
The Administrator may require independent review of any land use application that involves
tree removal and land clearing at the City's discretion.
The Administrator may authorize the planting of replacement trees on the site if it can be
demonstrated to the Administrator's satisfaction that replacement requirements in RMC 4-4-
130H1e can be met.
Tree retention standards shall be applied to the developable area, as defined in RMC 4-11-040,
Definitions D, of a property. A formal tree retention plan and tree retention worksheet
prepared by an arborist or landscape architect would be reviewed at the time of the land use
application.
Access: Access to the Longacres North Parking Garage would be via two existing curb cuts off
SW 16th St. The location of all ingress and egress driveways shall be subject to approval through
site plan review. Street improvements, including, curbs, gutter and sidewalk, are required along
the frontage of the property. No changes are proposed to the existing street frontage or
existing driveway cuts. Whenever a new construction in excess of $150,000 occurs, code
requires installation of street frontage improvements (RMC 4-6-060).
Critical Areas: According to City of Renton (COR) Maps, the Site contains high seismic hazard
areas and special flood hazard areas (100-year flood) FEMA Zone – AE. The seismic hazard is
related to potential liquefaction of soils during an earthquake event. A geotechnical analysis for
the site is required. The analysis needs to assess soil conditions and detail construction
measures to assure building stability.
If a project alters the base flood elevation (BFE) or boundaries of the special flood hazard area,
then the project proponent shall provide the community with engineering documentation and
analysis regarding the proposed change. If the change to the BFE or boundaries of the special
flood hazard area would normally require a FEMA Letter of Map Change, then the project
proponent shall initiate, and receive approval of, a FEMA Conditional Letter of Map Revision
(CLOMR) prior to approval of the development permit. The project shall be constructed in a
manner consistent with the approved CLOMR. If a CLOMR application is made, then the project
proponent shall also supply the full CLOMR documentation package to the Floodplain
Administrator to be attached to the floodplain development permit, including all required
property owner notifications. In addition, the applicant must provide Flood Hazard information
and a Biological Assessment with the required SEPA checklist.
Future improvements would be required to comply with Flood Hazard Area standards related to
flood proofing, compensatory storage, and construction techniques capable of resisting
hydrostatic and hydrodynamic loads. It is the applicant’s responsibility to ascertain whether
any additional critical areas or environmental concerns are present on the site during site
development or building construction.

Environmental Review: The proposed project would be subject to Washington State
Environmental Policy Act (SEPA) review as the proposal would include the construction of a
parking garage with more than 20 vehicle spaces. Therefore, an environmental checklist is a
submittal requirement. An environmental determination would be made by the Renton
Environmental Review Committee.
Land Use Permit Requirements: The proposed project would require Hearing Examiner Site, a
Lot Combination, and Environmental ‘SEPA’ Review. The 2023 land use application fees would
be as follows: Hearing Examiner Site Plan Review ($4,270), and Environmental (SEPA) Review
($1,800). Any applicable code Modifications would be $290 per modification. A 5% technology
fee would also be assessed at the time of land use application. All fees are subject to change
prior to submittal.
Detailed information regarding the land use application submittal can be found on the Site Plan
submittal checklist. Other informational applications and handouts can be found on the City’s
Digital Records Library. The city requires electronic plan submittal for all applications. Please
refer to the City’s Electronic File Standards.
In addition to the required land use permits, separate construction and building permits would
be required.
Public Information Sign: Public Information Signs are required for all Type II and Type III Land
Use Permits as classified by RMC 4-8-080. Public Information Signs are intended to inform the
public of potential land development, specific permits/actions being considered by the City, and
to facilitate timely and effective public participation in the review process. The applicant must
follow the specifications provided in the public information sign handout. The applicant is solely
responsible for the construction, installation, maintenance, removal, and any costs associated
with the sign.
Impact Fees: In addition to the applicable building and construction fees, impact fees would be
required. Fees change periodically and the fees in effect at the time of building permit issuance
would apply. For informational purposes, the 2023 impact fees are as follows:
• There is no Fire impact fee applicable to parking garages;
• A transportation impact fee for net new PM peak hour person vehicular trips, per PM
peak hour trip is assessed at $8,031.34 per new trip.
A handout listing all of the City’s Development related fees is available for your review at
www.rentonwa.gov.
Next Steps: When the formal application materials are complete, the applicant shall have the
materials pre-screened prior to submitting the complete application package. Please contact Jill
Ding, Senior Planner at jding@rentonwa.gov or 425-430-6598 to submit prescreen materials and
