DATE: October 20, 2022
TO: Pre-Application File No. PRE22-000339
FROM: Brittany Gillia, Associate Planner
SUBJECT: Duvall Short Plat
1902 Duvall Ave NE
(Parcel No. 5169700020)
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, 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 is proposing to subdivide one (1) existing single-family parcel into
two (2) lots. The project site is located at 1902 Duvall Ave NE (APN 5169700020) and is
approximately 16,384 sq. ft. (0.38 acres) in area. The subject parcel is located in the Residential-6
(R-6) zone and the Residential Medium Density Comprehensive Plan land use designation. The
existing 1,300 sq ft single-family residence is proposed to be partially demolished and would
remain on proposed Lot 1. Proposed Lot 1 would have an area of 9,337 sq. ft. and would access
off of NE 18th St via an existing driveway. Proposed Lot 2 would have an area of 7,047 sq. ft., and
would take access from NE 18th St via an access easement proposed through Lot 1. There are no
critical areas mapped on the project site.
Current Use: The property is developed with an existing single-family home that is proposed for
partial demolition (or full demolition if necessary) and a detached garage that is proposed to be
demolished.
Zoning/Density Requirements: The subject property is zoned Residential-6 (R-6). The minimum
density in the R-6 zone is 3.0 dwelling units per net acre (du/ac) and the maximum density is 6.0
du/ac. Private access easements, critical areas and public right-of-way (including frontage
dedications) are deducted from the total area to determine net density. For purposes of
calculating net density: All fractions shall be truncated at two numbers past the decimal. Should
a calculation result in a fraction of a dwelling unit that is 0.50 or greater, the fraction shall be
rounded up to the nearest whole number, for example, 4.56 dwelling units becomes 5.0. Should
Duvall Short Plat, PRE22-000339
Page 2 of 7
October 20, 2022
a calculation result in a fraction that is less than 0.50, the fraction shall be rounded down to the
nearest whole number, for example, 4.49 dwelling units becomes 4.0 dwelling units. The proposal
for two (2) lots on the 0.38 acre gross site area would result in a gross density of 5.3 dwelling units
per acre (2 lots / 0.38 acres = 5.3 du/ac). The applicant would be required to submit a density
worksheet demonstrating compliance with net density at the time of formal land use
application.
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).
Minimum Lot Size, Width and Depth – The minimum lot size permitted in Zone R-6 is 7,000 square
feet. For subdivided parcels that are less than one acre, one of the lots is allowed to be smaller
than the required minimum lot size. This single lot is allowed to be 6,250 square feet in the R-6
zone. Minimum lot width is 60 feet for interior lots, or 70 feet for corner lots. Minimum lot depth
is 90 feet. After required ROW dedication, it is unclear if the proposal would meet the minimum
standards for lot size and width. It is the applicant’s responsibility to demonstrate compliance
with the minimum lot size, width, and depth criteria of the zone at the time of formal
application.
Building Standards – The R-6 standards allow a maximum building coverage of 40% of the lot area.
The maximum impervious coverage in the R-6 zone is 55%. The maximum wall plate height is
restricted to 24 feet, and the buildings shall not be more than two 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 (4) vertical
feet 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 (1.5) horizontal feet from each façade for each one (1) vertical foot above the maximum wall
plate height. Detached accessory structures are restricted to a maximum wall plate height of 12
feet. The gross floor area must be less than that of the primary structure. Accessory structures
are also included in building lot coverage calculations. The proposal’s compliance with the
building standards for the existing home would be verified at time of land use review and
compliance for the new home would be verified at the time of building permit review.
Setbacks – Setbacks are the minimum required distance between the building footprint and the
property line and any private access easement or tract. The required setbacks for the R-6 zone
are: Front yard: 25 feet for the primary structure; Rear yard: 25 feet; Side yards: combined 15 ft.
with not less than 5 ft. on either side. Corner lots required to have a front yard and a secondary
front yard are relieved of the requirement to have a rear yard; in place of a rear yard setback, the
side yard setback of the zone shall apply. Lots adjacent to both public ROW and driveway tract
frontage are classified as corner lots. The submitted materials do not demonstrate compliance
with secondary front yard building setbacks on proposed Lot 1. Setback compliance for the
existing home would be verified at time of land use review and compliance for the new homes
would be verified at the time of building permit review. The existing home would be required
to meet setbacks prior to recording the short plat document.
Residential Design and Open Space Standards: The Residential Design and Open Space Standards
contained in RMC 4-2-115 would be applicable to any new residential structures.
Duvall Short Plat, PRE22-000339

October 20, 2022
Access /Parking: Access to proposed Lot 1 would be via the existing curb cut off of NE 18th St and
access to Lot 2 is proposed via an access easement running through Lot 1 connecting to NE 18th
St. Shared driveways may be allowed for access to four (4) or fewer residential lots, provided:
a. At least one of the four (4) lots abuts a public right-of-way and the street frontage of the lot is
equal to or greater than the lot width requirement of the zone;
b. The subject lots are not created by a subdivision of ten (10) or more lots;
c. A public street is not anticipated by the City of Renton to be necessary for existing or future
traffic and/or pedestrian circulation through the short subdivision or to serve adjacent property;
d. The shared driveway would not adversely affect future circulation to neighboring properties;
e. The shared driveway is no more than three hundred feet (300') in length; and
f. The shared driveway poses no safety risk and provides sufficient access for emergency vehicles
and personnel.
Shared driveways shall be within a tract; 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. 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. Any driveway shall be setback at least 5 feet from the side lot lines (unless utilizing
a joint driveway). The applicant is proposing to access proposed Lot 2 off of an access easement
stemming off of NE 18th St., however, the lot layout does not comply with general requirements
and minimum standards for residential access per RMC 4-6-060. The project layout would need
to be revised to comply with the shared driveway standards. Compliance with access and street
standards would be required to be demonstrated at the time of preliminary short plat
application.
Parking: Each lot is required to accommodate off-street parking for a minimum of two vehicles.
Compliance with parking regulations would be verified at the time of building permit review.
Driveways: Driveways exceeding 8% must provide slotted drains at the lower end of the driveway.
The maximum driveway slopes cannot exceed 15%. If the grade exceeds 15%, a variance is
required. The maximum width of single loaded garage driveways shall not exceed 9 feet and
double loaded garage driveways shall not exceed 16 feet. Compliance with the driveway
regulations would be verified at the time of formal land use review.
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 or grading plan. A fence and/or wall detail
should also be included on the plan. A fence taller than 6 feet shall require a building permit or
an explicit exemption from the Building Official. 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
Duvall Short Plat, PRE22-000339
Page 4 of 7
October 20, 2022
height of a standalone fence. For more information about fences and retaining walls refer to RMC
4-4-040.
Landscaping: With the exception of critical areas, all pervious area shall have landscape
treatment. Landscaping may include hardscape such as decorative paving, rock outcroppings,
fountains, plant containers, etc. Ten feet (10') of on-site landscaping is required along all public
street frontages. Street trees and landscaping are required within the Right of Way on public
streets. 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 per subsection L2 of RMC 4-4-070 shall be planted within right of way planting strips
pursuant to the standards in subsection F.2 of RMC 4-4-070, provided there shall be a minimum
of one street tree planted per lot. Where there is insufficient right-of-way space or no public
frontage, street trees are required in the front yard subject to approval of the Administrator. A
minimum of two (2) trees are to be located in the front yard prior to final inspection. A conceptual
landscape plan shall be provided with the formal land use application as prepared by a
registered Landscape Architect, a certified nurseryman or other certified professional.
Significant Tree Retention: Staff review of aerial images of the site identifies there are mature
trees on the site. If 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. The Administrator may authorize the planting of
replacement trees on the site if it can be demonstrated to the Administrator's satisfaction that an
insufficient number of trees can be retained. Please refer to Tree Retention and Land Clearing
Regulations RMC 4-4-130 for further general and specific tree retention and land clearing
requirements.
If significant trees are proposed to be removed, a tree inventory and a tree retention plan along
with a tree retention worksheet shall be provided with the formal land use application. The tree
retention plan must show preservation of at least thirty-percent (30%) of significant trees, and
indicate how proposed building footprints would be sited to accommodate preservation of
significant trees that would be retained.
Tree Credit Requirements: With the exception of interior remodels not involving any building
addition, removal of trees, or alteration of impervious areas, properties subject to an active land
development permit shall comply with all of the following minimum tree credit requirements, and
apply the tree credit value table at (H.1.b.v).

iv. Within subdivisions, location of supplemental tree replanting shall be prioritized
within tree tract(s) versus individual lots.
v. Tree credit value for each tree, existing or new, is assigned as shown in the following
table:
All significant trees required to be retained shall be preserved in the priority order listed below,
with Priority One trees being the highest priority. Applications that propose retention of lower
priority trees in lieu of Priority One trees must demonstrate in writing to the Administrator’s
satisfaction that: (1) all reasonable efforts have been taken to preserve trees utilizing the highest
priority possible, (2) that retention of higher priority trees is not feasible or practical for the
project site, and (3) that the project proposal meets or exceeds the purposes and intent of this
Section. Significant trees shall be retained in the following priority order:
Priority One
i. Landmark trees;
ii. Significant trees that form a continuous canopy;
iii. Significant trees on slopes greater than twenty percent (20%);
iv. Significant trees adjacent to critical areas and their associated buffers;

v. Significant trees over sixty feet (60') in height or greater than eighteen inches (18")
caliper; and
vi. 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
i. Healthy tree groupings whose associated undergrowth can be preserved;
ii. Other significant native evergreen or deciduous trees; and
iii. 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
If staff determines that the trees cannot be retained, replacement trees, with at least a 2-inch
caliper or an evergreen at least 6 feet tall, shall be planted at a rate of 12 caliper inches of new
trees to replace each protected tree removed. Protected trees that do not contribute to a lot's
required minimum tree density shall be held in perpetuity within a tree protection tract.
The Administrator may require independent review of any land use application that involves tree
removal and land clearing at the City's discretion.
If staff determines that the trees cannot be retained, replacement trees, with at least a 2-inch
caliper or an evergreen at least 6 feet tall, shall be planted at a rate of 12 caliper inches of new
trees to replace each protected tree removed. A formal arborist report, tree retention plan and
tree retention worksheet prepared by an arborist or landscape architect would be required at
the time of the Preliminary Short Plat application.
Critical Areas: According to COR Maps, there are no critical areas mapped on the project site. 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: Short plats are categorically exempt from Environmental (SEPA) Review
except for lands covered by water or critical areas as designated in RMC 4-9-070H.2. The proposed
short plat would no longer be exempt from environmental review if further investigation of the
site results in the identification of designated critical areas.
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 2022
administrative short plat application fee is $5,410.00. Each modification request is $260.00. A 5%
technology fee 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. 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 it’s associated fee, will be required following construction of the short plat’s
infrastructure.

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.
Fees change periodically and the fees in effect at the time of building permit issuance would apply.
For informational purposes, the 2022 impact fees are as follows:
