Memorandum
DATE: September 26, 2024
TO: Pre-Application File No. 24-000256
FROM: Mariah Kerrihard, Assistant Planner
SUBJECT: Serduk Short Plat – 3500 Park Ave N
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 applicant proposes to subdivide 3500 Park Ave N (APN 3342103170) into
two (2) residential lots for the benefit of detached dwellings. The property has street frontage
along Park Avenue N and is located within the Residential-6 (R-6) zone. The site area is
approximately 13,650 square feet (0.31 acre). Access is proposed via a private access easement
from Park Avenue N. There are sensitive slopes mapped on the property per City of Renton (COR)
maps.
Current Use: The project area is currently developed with a 1,450 square foot single family
dwelling. Access to the detached dwelling is from Park Avenue N. The existing dwelling is
proposed to be retained on Lot 2.
1. Zoning /Land Use Designation, and Overlays: The subject property is located within the
Residential-6 (R-6) zoning classification. The Residential Medium Density Land Use
designation is intended to implement the R-6 zone. The R-6 zone is established for single
family dwellings. Development in the R-6 zone is intended to be single family residential at
moderate density. Detached dwellings are permitted within the R-6 zone and one (1) ADU is
permitted per legal lot.1
1 “Missing middle” house bills for housing (E2SHB 1110) and accessory dwelling units (EHB 1337).

PRE24-000256_PlanningComments_240908
2. Development Standards: The project would be subject to RMC 4-2-110A, “Development
Standards for Single Family Zoning Designations” effective at the time of complete application
(noted as “R-6 standards” herein).
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 streams 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 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-6 zone has
a minimum density of three (3) dwelling units per acre with a maximum of six (6) dwelling
units per acre. A density worksheet was not included with the pre-application submittal
materials; therefore, staff was unable to verify compliance with the density requirements.
A completed density worksheet would be required with the land use application. The
applicant would be required to demonstrate compliance with the net density requirements
of the zone at the time of formal application.
Minimum Lot Size, Width and Depth – The minimum lot size permitted in the R-6 zone is 7,000
square feet for parcels being subdivided. Minimum lot width is 60 feet (60’); minimum lot
depth is 90 feet (90’); minimum lot width for corner lots is 70 feet (70’). 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 6,250 square feet in size in the R-6 zone.
Submitted plans would need to show compliance with the required lot size and dimensional
standard with the land use application.
Building Standards – The R-6 standards allow a maximum building coverage of 40 percent
(40%) of the lot area. The maximum impervious coverage in the R-6 zone is 55 percent (55%).
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 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. Building elevations were not included with the
submitted pre-application materials, therefore staff was unable to verify compliance with
the Building Height requirements. 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.

PRE24-000256_PlanningComments_240908
Setbacks – Setbacks are the minimum required distance between the building footprint and
the property line. The required setbacks for the R-6 zone are: Front yard: 25 feet (25’); Rear
yard: 25 feet (25’); Side yards: combined 15 feet (15’) with not less than 5 feet (5’) on either
side; and secondary front yards: 25 feet (25’). 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.
3. Residential Design and Open Space Standards: 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.
4. 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 is 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 application 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.

5. Significant Tree Retention: A review of COR Maps appears to show 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.

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-
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.
6. Fences/Retaining 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.
7. Access/Driveways: Access to both lots is proposed from Park Avenue N via an ingress
easement along the west side of Lot 1. 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. One driveway is permitted per
each one hundred sixty-five feet (165’) of street frontage. Driveways and driveway
approaches in the public right-of-way shall be paved with asphaltic concrete, cement, or
equivalent alternative materials of a permanent nature as approved by the Public Works
Department. Surfacing treatments that provide increased infiltration opportunities, such as
permeable pavements, shall be used where feasible and consistent with the Surface Water
Design Manual. Driveways shall not be closer than five feet (5’) to any property line except as
allowed per RMC 4-4-080I9, Joint Use Driveways. The proposed layout included a private

access easement from Park Avenue N. When permitted, shared driveways may be allowed
for access to no more than four (4) residentially zoned lots and must be wholly within a
tract. The tract shall be shown and recorded on the face of the plat to be preserved in
perpetuity. Shared driveways shall be the width of the tract and paved surface shall be a
minimum of sixteen feet (16'); the Fire Department may require the tract and paved surface
to be up to twenty feet (20') wide. If a shared driveway abuts properties that are not part
of the subdivision, an eight foot (8') wide landscaped strip shall be provided between the
shared driveway and neighboring properties. The landscape strip shall be within a tract and
planted with a mixture of trees, shrubs, and groundcover, as required in RMC 4-4-070. The
shared driveway may be required to include a turnaround per subsection H of this Section.
No sidewalks are required for shared driveways; however, drainage improvements pursuant
to City Code are required (i.e., collection and treatment of stormwater), as well as an
approved pavement thickness. The maximum grade for the shared driveway shall not
exceed fifteen percent (15%), except for within approved hillside subdivisions. In addition to
the shared driveway tract, an access easement shall be recorded with the King County
Recorder’s Office and be shown on the face of the plat to encumber the entirety of the tract.
For more information about shared driveway standards refer to RMC 4-6-060J.Compliance
with access and driveway requirements would be verified at the time of land use
application.
8. Critical Areas: According to COR Maps, there are sensitive slopes mapped on the property.
Due to the presence of geological hazards, a geotechnical study may be required at the time
of building permit application. The study shall specifically address if the proposal will not
increase the threat of the geological hazard to adjacent or abutting properties beyond pre-
development conditions; and the proposal will not adversely impact other critical areas; and
the development can be safely accommodated on the site. It is the applicant’s responsibility
to determine whether any other critical areas are present on the site prior to formal land
use application.
9. Permit Requirements: The proposal would require administrative short plat approval. The
application would be reviewed within an estimated time frame of six to eight weeks. The 2024
fees would total $6,384.00 ($6,080.00 Preliminary Short Plat + $304.00 Technology Fee (5%)
= $6,384.00). 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.
10. Public Information Sign: Public Information Signs are required for all Type II 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.
