DATE: September 18, 2025
TO: Pre-Application File No. 25-000273
FROM: Jill Ding, Senior Planner
SUBJECT: Riu Development – 13012 80th Ave S, Renton, WA 98178
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 subject property is located at 13012 80th Ave S (APN 2144800325) at
the southeast corner of S 130th St and 80th Ave S. The project site totals 22,667 square feet
(0.52 acres) in area and is currently developed with a single-family home and a detached
accessory structure (garage) which are proposed for removal. The site has a Comprehensive
Plan Land Use of Designation of Residential Medium Density (RMD) and a zoning designation
of Residential-8 (R-8). The applicant is proposing to subdivide the project site into four (4) lots
for the future construction of single family residences with attached accessory dwelling units
(ADUs). Access to the site is proposed via residential driveways off 80th Ave S, however the
applicant is also proposing to retain the existing driveway curb cut off S 130 th St for Lot A.
According to the Geotechnical Assessment, the property is mapped with sensitive slopes,
erosion hazard areas, high landslide hazard areas, low seismic hazard area, and a stream
buffer from a Type Np stream located off-site to the east.
Current Use: The project site is currently developed with a 1,580 sq. ft. single-family home
and a detached 480 sq. ft. garage, which are proposed for removal.
1. Zoning /Land Use Designation, and Overlays: The subject property is located within the
R-8 zoning classification. The density range allowed in the R -8 zone is a minimum of 4.0
to a maximum of 8.0 dwelling units per one net acre. The Residential Medium Density
(RMD) Land Use designation Apply to areas that can support high-quality, compact,
urban development with access to urban services, transit, and infrastructure, whether
through new development or through infill development. Detached single family
Riu Development
Page 2 of 7
September 18, 2025
residential dwelling units are permitted uses within the R-8 zoning designation. Two
(2) accessory dwelling units (ADUs) are allowed per legal lot as an accessory use to
a principal dwelling, subject to RMC 4-2-110C.
The area of public and private streets (including driveway tracts and private access
easements) and critical areas would be deducted from the gross site area to determine
the “net” site area prior to calculating density.
The proposal for four (4) lots would result in a gross density of 7.69 dwelling units per acre
(4 lots / 0.52 acres = 7.69 du/ac). The project would need to meet density
requirements using “net” square footage, following the deduction of any required
right-of-way or critical areas. A Density Worksheet demonstrating compliance with
the net density requirements would be required at the time of formal short plat
application.
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-8 standards” herein).
Minimum Lot Size, Width and Depth – The minimum lot size in the R-8 zone is 5,000 sq.
ft. The minimum lot width is 50 feet for interior lots and 60 ft. for corner lots and the
minimum lot depth is 80 feet. Additionally, the subdivision regulations require new
residential lots to contain a minimum width at their foremost points (where the front
property line meets ROW or private access) of no less than 80-percent of the required lot
width and no new lots shall have a depth-to-width ratio greater than four to one.
As shown on the table below, the proposed lots would have the following dimensions:
Width Depth Area
Lot A 60.1’ 100’ 6,000.5 sq. ft.
Lot B 50’ 100’ 5,000 sq. ft.
Lot C 50’ 100’ 5,000 sq. ft.
Lot D 66.7’ 100’ 6,680 sq. ft.
It appears that Lots C and D would include the wetland/stream buffer area within
their lots, which is not permitted. The wetland/stream buffer would need to be within
a separate Native Growth Protection Area (NGPA) tract and record a permanent and
irrevocable covenant running with the land or deed restriction on the property title
of any critical area management tract or tracts created as a condition of a permit.
Such covenant or deed restriction(s) shall prohibit development, alteration, or
disturbance within the tract except for purposes of habitat enhancement as part of
an enhancement project which has received prior written approval from the City,
and from any other agency with jurisdiction over such activity. A covenant running
with the land shall be placed on the tract restricting its separate sale. Each abutting
lot owner or the homeowners’ association shall have an und ivided interest in the
Riu Development
Page 3 of 7
September 18, 2025
tract. All other lots appear to comply with the minimum lot size, width and depth
requirements of the R-8 zone.
Building Standards – The R-8 standards allow a maximum building coverage of 50% of
the lot area. The maximum impervious coverage in the R -8 zone is 65%. Compliance
with the maximum building and impervious surface coverage requirements for the
R-8 zone would be verified at the time of formal building permit 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 for
the primary structure, except when all vehicle access is taken from an alley, then 15 ft;
Rear yard: 25 feet; Side yards: 5 feet; and Secondary Front yard: 15 feet. 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. Compliance with the setback requirements for the proposed residences
would be verified at the time of formal building permit application.
3. Residential Design and Open Space Standards: All single family residences would be
subject to the Residential Design Standards for the R -8 zone, outlined in RMC 4-2-115.
Residential Design Review occurs as part of the Building Permit Review.
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 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
formal land use application as prepared by a registered Landscape Architect or
other certified professional.
5. 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
Riu Development
Page 4 of 7
September 18, 2025
Regulations for further general and specific tree retention and land clearing
requirements.
In addition to retaining a minimum of 30% of existing significant trees, properties subject
to an active land development permit shall comply with minimum tree credit retention
requirements of a minimum of 30 credits per net acre. Tree credits encourage re tention
of existing significant trees with larger trees being worth more tree credits.
TREE SIZE TREE CREDITS
New small species tree 0.25
New medium species tree 1
New large species tree 2
Preserved tree 6 – 9 caliper inches 4
Preserved tree 10 – 12 caliper inches 5
Preserved tree 12 – 15 caliper inches 6
Preserved tree 16 – 18 caliper inches 7
Preserved tree 19 – 21 caliper inches 8
Preserved tree 22 – 24 caliper inches 9
Preserved tree 25 – 28 caliper inches 10
Preserved tree 29 – 32 caliper inches 11
Preserved tree 33 – 36 caliper inches 12
Preserved tree 37 caliper inches and greater 13
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 o r
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
Riu Development
Page 5 of 7
September 18, 2025
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. If any trees are located onsite, 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 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. For more
information about fences and retaining walls refer to RMC 4-4-040. It appears retaining
walls would be proposed along the joint property lines. Compliance regarding the
proposed retaining walls would be verified at the time of formal land use
application.
7. Access/Driveways/Parking: Access to the site is proposed via residential driveways off
80th Ave S, however the applicant is also proposing to retain the existing driveway curb
cut off S 130th St for Lot A.
In accordance with the driveway standards, RMC 4-4-080I, 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 driveway standards would be verified at the
time of building permit review. Each lot is required to accommodate off street parking for
a minimum of two vehicles. A minimum of one space is required for each ADU.
Alley access is the preferred street pattern for all new residential development except in
the Residential Low Density land use designation (RC, R-1, and R-4 zones) and the R-6
zone. All new residential development in an area that has existing alleys shall utilize alley
access. New residential development in areas without existing alleys shall utilize alley
access for interior lots. If the developer or property owner demonstrates that alley access
is not practical, the use of alleys may not be required. Conformance with access and
parking requirements would be reviewed at the time of formal land use application.
8. Critical Areas: According to the Geotechnical Assessment, the property is mapped with
sensitive slopes, erosion hazard areas, high landslide hazard areas, low seismic hazard
area, and a stream buffer from a Type Np stream located off-site to the east. A standard
stream study would be required to be prepared by a qualified biologist and
submitted with the land use application. Stream buffers are required to be protected
within a Native Growth Protection Area (NGPA) tract.

In addition, due to the presence of geological hazards, a geotechnical study would
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.
PLEASE NOTE, the City is currently in the process of updating its critical areas
regulations. It is anticipated that the new regulations would be adopted by the end
on 2025.
9. Environmental Review: Short Plats are generally exempt from State Environmental
Policy Act (SEPA) review; however, the project would be subject to Environmental Review
as it appears that a stream buffer is located on the property.
10. Permit Requirements: The proposal would require Preliminary Short Plat approval and
Environmental (SEPA) Review. All applications would be reviewed concurrently within an
estimated timeframe of six to eight weeks. The 2025 fees would total is $8,530.20 ($6,268
Preliminary Short Plat + $1,856 SEPA + $406.20 Technology Fee). Any modifications
requested would be an additional $313.95 ($299 plus a 5% Technology Surcharge Fee).
All fees are subject to change. Detailed information regarding the land use permit
application submittal requirements can be found on the Short Plat Submittal

submittal requirements and may be modified in cases where additional information is
required to complete the review of an application. In addition, non-applicable submittal
requirements may be waived. The applicant should contact the assigned Project
Manager if there are any questions regarding submittal requirements.
12. 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.
13. Impact 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 2025 impact fees are as follows:
• A Transportation Impact Fee assessed at $11,485.67 per each new detached
dwelling unit and $5,742.84 per new ADU.
