1. The fire flow requirement for a single-family home is 1,000 gpm minimum for dwellings
up to 3,600 square feet (including garage and basements). If the dwelling exceeds 3,600 square
feet, a minimum of 1,500 gpm fire flow would be required. A minimum of on e fire hydrant is
required within 300-feet of the proposed buildings and two hydrants if the fire flow goes up to
1,500 gpm. The existing water main is a dead end 8 inch main with limited fire flow capability
and thus any homes over the 3,600 square feet limit would be required to be equipped with an
approved fire sprinkler system. It appears that there is one existing fire hydrant that will meet
the minimum requirements.
2. The fire impact fees are currently applicable at the rate of $829.77 per single family unit.
This fee is paid at building permit issuance. No charges apply to the existing homes that are to
remain or if they are replaced with new homes.
3. Fire department apparatus access roadways are required to be a minimum of 20-feet
wide fully paved, with 25-feet inside and 45-feet outside turning radius. Fire access roadways
shall be constructed to support a 30-ton vehicle with 75-psi point loading. Access is required
within 150 feet of all points on the buildings. The maximum grade is 15 percent. Dead end
roadways that exceed 150 feet require an approved fire apparatus turnaround, none exists
now. Dead end roadways over 300 feet long require a full 90-foot diameter cul-de-sac.

DATE: September 7, 2023
TO: Pre-Application File No. 23-000264
FROM: Andrew Van Gordon, Associate Planner
SUBJECT: Lambro Short Plat – 301 NW 7th St (Parcel number 9564800012)
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
https://www.codepublishing.com/WA/Renton/.
Project Proposal: The applicant proposes to subdivide 301 NW 7th St (APN 9564800012) into two
(2) residential lots for the benefit of detached dwellings. The property has street frontage along
NW 7th St to the north. The lot is located within the Residential – 8 (R-8) zone. Per COR Maps, the
property is approximately 11,068 square feet (0.25 acre). Access is proposed via NW 7th St.
Current Use: The project area is currently developed with a detached dwelling with access from
NW 7th St. The existing dwelling is proposed to be retained. Per COR Maps a high erosion hazard
area, sensitive slopes and protected slopes are present on the site.
Zoning/Land Use: The subject property is located within the Residential-8 (R-8) zoning
classification. The Residential Medium Density Land Use designation is intended to implement the
R-8 zone. The R-8 zone is established for single family dwellings. Development in the R-8 Zone is
intended to create opportunities for new single family residential neighborhoods and to facilitate
high-quality infill development that promotes reinvestment in existing single-family
neighborhoods. It is intended to accommodate uses that are compatible with and support a high-
quality residential environment and add to a sense of community.
Detached dwellings are permitted within the R-8 zone.
Density: The area of public rights-of-way, legally recorded private access easements and critical
areas (i.e. very high landslide hazard areas, protected slopes (except evaluate on a case-by-case
basis those protected slopes created by previous development, wetlands, Class 1 to 4 st reams
and lakes or floodways) would be deducted from the gross site area to determine the “net” site
area prior to calculating density. In order to calculate the proposed density of the project, any
Lambro Short Plat
Page 2 of 7
September 7, 2023
area of public road, private driveway/easement, and/or critical area dedication must be known.
All fractions which result from net density calculations shall be truncated at two (2) numbers past
the decimal (e.g., 4.5678 becomes 4.56). Calculations for minimum or maximum density that
result in a fraction that is 0.50 or greater shall be rounded up to the nearest whole number. Those
density calculations resulting in a fraction that is less than 0.50 shall be rounded down to the
nearest whole number. The R-8 zone has a minimum density of four (4) dwelling units per acre
with a maximum of eight (8) dwelling units per acre.
It is unclear what the gross density is. The provided documents do not identify the existing lot
layout. The project information on the provided site plan identifies that 217 NW 7th St (APN
42202401155) is included as part of the project, however, the project narrative identifies 301
NW 7th St (APN 956480012) as the lone project site. Further, the project narrative identifies the
project area as 11,400 square feet, but COR Maps identifies 301 NW 7th St as 11,068 square feet;
the combined square footage of 301 and 217 NW 7th St would be 17,898 square feet. If a portion
of 217 NW 7th St is included as part of the subdivision, then the entirety of the lot needs to be
included as part of the subdivision. Based on the materials provided, it is not clear if it is included
in the subdivision.
The applicant would be required to demonstrate compliance with the net density requirements
of the zone at the time of formal application. A density worksheet deducting street
improvements identified in the preapplication meeting and this memo would be required with
the land use application.
Development Standards: The project would be subject to RMC 4-2-110A, Development Standards
for Residential Zoning Designations effective at the time of complete application (noted as “R-8
standards” herein).
Minimum Lot Size, Width and Depth – The minimum lot size permitted in the R-8 zone is 5,000
square feet for parcels being subdivided. For short plats of parcels smaller than one (1) acre, one
(1) parcel may be allowed to be smaller than the required minimum lot size. If all other parcels
meet the required minimum lot size standard of the zone, one parcel may be allowed to be 4,500
square feet in size in the R-8 zone. Minimum lot width is 50 feet (50’); minimum lot depth is 80
feet (80’). In order to ensure compliance with Tier 1 requirements for Tree Preservation Priority,
pursuant to RMC 4-4-130H2a, lot size and lot dimensions of the zone may be decreased by a
maximum of 10 percent (10%), provided the applicant can demonstrate to the Administrator’s
satisfaction that the reduction is necessary to ensure the preservation of all significant trees, as
defined in RMC 4-11-200, required for retention within dedicated tract(s), pursuant to RMC 4-4-
130H1a, Minimum Tree Retention Requirements.
It is not clear if the proposed lots are meeting standards. Protected slopes and their buffers are
required to be placed in a tract and cannot be incorporated into lots. The slope critical areas and
their buffers are not shown on the drawing. Compliance with minimum lot size, width and depth
standards would be verified at the time of land use application.
Building Standards – The R-8 standards allow a maximum building coverage of 50 percent (50%)
of the lot area. The maximum impervious coverage in the R-8 zone is 65 percent (65%). The
maximum wall plate height is restricted to 24 feet (24’), and the buildings shall be not more than
two (2) stories. Roofs with a pitch equal to or greater than 4:12 may project an additional six (6)
vertical feet from the maximum wall plate height; common rooftop features, such as chimneys,
may project an additional four vertical feet (4’) from the roof surface. Non-exempt vertical
Lambro Short Plat
Page 3 of 7
September 7, 2023
projections (e.g., decks, railings, etc.) shall not extend above the maximum wall plate height
unless the projection is stepped back one-and-a-half horizontal feet (1.5’) from each façade for
each one vertical foot (1’) above the maximum wall plate height. The maximum wall plate height
for detached accessory structures is 12 feet (12’) and the total floor area must be less than that
of the primary structure. Accessory structures are also included in building lot coverage
calculations.
New development would need to comply with the maximum building coverage, impervious
surface requirements, and building height regulations of the zone at the time of building permit
review. Existing development proposed for retention would also be required to comply with
building and coverage limitations and would be reviewed for compliance at the time of land use
application.
Setbacks – Setbacks are the minimum required distance between the building footprint and the
property line. The required setbacks for the R-8 zone are: Front yard: 20 feet (20’) except when
all vehicle access is taken from an alley, then 15 feet (15’); Secondary front yard (applies to corner
lots): 15 feet (15’); Rear yard: 25 feet (25’); Side yard: five feet (5’) Within subdivisions, the
minimum front yard and secondary front yard setback may be reduced to no less than twenty feet
(20') provided the applicant can demonstrate to the Administrator’s satisfaction that the setback
reduction is necessary to preserve and maintain a landmark tree within a tree protection tract, as
each term is defined in RMC 4-11-200, Definitions T. An arborist report, pursuant to RMC 4-8-
120D.1, shall be prepared and provided to the City for review and concurrence, demonstrating
that the setback reduction and project proposal serve to preserve the critical root zone of the tree
within a tree protection tract.
Compliance with required setbacks for new development would be verified at the time of
building permit application. Existing development proposed for retention would be reviewed for
compliance at the time of land use application.
Residential Design and Open Space Standards
Future single-family building permits would be subject to the RMC 4-2-115, Residential Design
and Open Space Standards. Requirements related to garages, entries, modulation,
windows/doors, scale, bulk, and character, roof forms, eaves, architectural detailing, and
materials/color should be reviewed in their entity prior to submitting permit applications.
Compliance with lot configuration requirements would be verified at the time of land use
application. Compliance with building design requirements would be verified at the time of
building permit review.
Access/Parking: Access to the lots are proposed via NW 7th St. Each lot is required to
accommodate off street parking for a minimum of two (2) vehicles. The maximum width of single
loaded garage driveways shall not exceed nine feet (9’) and double loaded garage driveways shall
not exceed 16 feet. Maximum driveway slopes shall not exceed 15 percent; provided, that
driveways exceeding eight percent (8%) shall provide slotted drains at the lower end with positive
drainage discharge to restrict runoff from entering the garage/residence or crossing any public
sidewalk. Driveways shall not be closer than five feet (5’) to any property line except as allowed
per RMC 4-4-080I.9, Joint Use Driveways.
Access designs were not included. A joint-use driveway would be preferred. Compliance with
access and driveway requirements would be verified at the time of land use application.

September 7, 2023
Landscaping: With the exception of 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. The minimum on-site landscape width required
along street frontages is 10 feet and shall contain trees, shrubs, and landscaping. Street trees in
the ROW planter will also be required. Landscaping may include hardscape such as decorative
paving, rock outcroppings, fountains, plant containers, etc. Minimum planting strip widths
between the curb and sidewalk are established according to the street development standards of
RMC 4-6-060, Street Standards. Street trees and, at a minimum, groundcover are to be located in
this area when present. Street trees shall be planted in the center of the planting strip between
the curb and the sidewalk at the following intervals; provided, that, where right-of-way is
constrained, irregular intervals and slight increases or decreases may be permitted or required.
Additionally, trees shall be planted in locations that meet required spacing distances from
facilities located in the right-of-way including, but not limited to, underground utilities,
streetlights, utility poles, traffic signs, fire hydrants, and driveways; such spacing standards are
identified in the City’s Approved Tree List. Generally, the following spacing is required: i. Small-
sized maturing trees: thirty feet (30') on center; ii. Medium-sized maturing trees: forty feet (40')
on center; and iii. Large-sized maturing trees: fifty feet (50') on center.
A conceptual landscape plan shall be provided with the land use applica tion as prepared by a
licensed Landscape Architect, a certified nurseryman or other certified professional. Please be
aware that frontage improvements will be required.
Storm drainage facilities are required to comply with the minimum 15-foot perimeter
landscaping strip on the outside of the fence unless otherwise determined through the site plan
review or subdivision review process. Please refer to landscape regulations RMC 4-4-070 for
further general and specific landscape requirements.
Significant Tree Retention: 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.

Protected trees within a subdivision shall be retained in the order of priority listed in RMC 4 -4-
130H.2. Protection of trees or groves by placement within a dedicated tract (Tier 1) is the highest
priority.
Significant trees shall be retained in the following priority order:
Priority One: Landmark trees; significant trees that form a continuous canopy; significant trees on
slopes greater than twenty percent (20%); significant trees adjacent to critical areas and their
associated buffers; significant trees over sixty feet (60') in height or greater than eighteen inches
(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-
130H.1.e 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.

Fences/Walls: If the applicant intends to install any fences or retaining walls as part of this project,
the location must be designated on the landscape plan and grading plan with top of wall and
bottom of wall elevations. 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. The maximum height
of any fence or retaining wall is 72-inches subject to further height limitations in setbacks and
clear vision areas noted in RMC 4-4-040D. 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. For more information about fences and retaining walls refer
to RMC 4-4-040.
Hillside Subdivisions: Because of their steeper slopes, the sites of hillside subdivisions ordinarily
should have greater attention paid to the potential for drainage, erosion, and slope stability
problems than other subdivisions. Information concerning the soils, geology, drainage patterns,
and vegetation shall be presented in order to evaluate the drainage, erosion control and slope
stability for site development of the proposed plat. The applicant must demonstrate that the
development of the hillside subdivision will not result in soil erosion and sedimentation, landslide,
slippage, excess surface water runoff, increased costs of building and maintaining roads and public
facilities and increased need for emergency relief and rescue operations. Detailed plans for any
proposed cut and fill operations shall be submitted. These plans shall include the angle of slope,
contours, compaction, and retaining walls. Plans shall be consistent with requirements in RMC 4-
4-060, Grading, Excavation and Mining Regulations. Areas of the subdivision deemed to be critical
areas due to designation as protected slopes shall be located within a tract or tracts. See RMC 4-
7-220, Hillside Subdivisions for full requirements.
Critical Areas: Per COR Maps a high erosion hazard area, sensitive slopes (>25% & <= 40% slope)
and protected slopes (>40% & <=90% slope) are present on the site.
A geotechnical report would be required at the time of the land use application.
Environmental Review: Short Plats are generally exempt from State Environmental Policy Act
(SEPA) review. However, the proposal would require environmental review pursuant to RMC 4-9-
070, Environmental Review Procedures. The project site has protected slopes located on it per
COR Maps; WAC 197-11-800(3) does not apply. An Environmental Checklist must be submitted
with the proposal and the City’s Environmental Review Committee is required to issue a Threshold
Determination prior to any issuance for permits on the site.
Permit Requirements: The proposal would require administrative short plat approval and
Environmental Review. The application would be reviewed within an estimated time frame of
eight weeks. The 2023 fees would total $8,274.00 ($6,080.00 Preliminary Short Plat + $1,800.00
Environmental Review + $394.00 Technology Fee (5%) = $8,274.00). Each modification request is
$290.00. A 5% technology fee added to the total cost of the reviews would also be assessed at the
time of land use application. All fees are subject to change. Detailed information regarding the
land use permit application submittal requirements can be found on the Short Plat Submittal
Requirements 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. A Final Short Plat application, and its associated fee,
will be required following construction of the subdivision’s infrastructure.

Public Information Sign: Public Information Signs are required for all Type II Land Use Permits as
classified by RMC 4-8-080, Permit Classification. 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.
Fees: In addition to the applicable building and construction fees, impact fees would be required.
The fee in effect at the time of residential building permit issuance will apply. For informational
purposes, the 2023 impact fees are as follows:
• A Transportation Impact Fee assessed at $12,208.54 per each new detached dwelling unit.
• A Parks Impact Fee assessed at $3,276.44 per each new detached dwelling unit subdivision.
• A Fire Impact Fee assessed at $829.77 per each new detached dwelling unit.
• A Renton School District Impact Fee assessed at $2,911.00 (plus a 5% processing charge)
per each new detached dwelling unit.
A handout listing Renton’s development-related fees is available on the City of Renton website
for your review.
Next Steps: When the formal land use application materials are complete, the applicant shall have
the application materials pre-screened prior to submitting the complete application package.
Please contact Andrew Van Gordon, Associate Planner at avangordon@rentonwa.gov or (425)
430-7286 for an appointment.
Expiration: Upon approval, the Short Plat is valid for five years with a possible one-year extension
(RMC 4-7-070M). It is the responsibility of the owner to monitor the expiration date.
