NOTE: The applicant is cautioned that information contained in this summary is preliminary and non-
binding and may be subject to modification and/or concurrence by official city decision-makers.
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.
I have completed a preliminary review for the above-referenced proposal located at 1805 Lake Ave
S. The following comments are based on the pre-application submittal made to the City of Renton
by the applicant.
EXISTING CONDITIONS
The site is approximately 0.35 acres in size and is rectangular in shape. There is an existing single-
family residence with an accessory building.
Water Water service is provided by the City of Renton. The site is in the West Talbot Hill service
area in the 300 hydraulic pressure zone. There is an existing 8-inch City water main located
in Lake Ave S (see Water plan no. W-319803) that can deliver a maximum total flow capacity
of 2,000 gallons per minute (gpm). The approximate static water pressure is 93 psi at
ground elevation of 85 feet. There is an existing ¾-inch water service to the existing single-
family home (Facility ID No. MTR-002058). The site is located outside of the Wellhead
Protection Area Zone.
Sewer Wastewater service is provided by the City of Renton. There is an existing 8-inch concrete
gravity wastewater main located in Lake Ave S (see City plan no. S-00220B). There is also
a private 6-inch sewer stub going into the property on the east side of the site.
Storm There is an existing 8-inch stormwater main in Lake Ave S (see City plan no. D-212401). The
existing property does not contain stormwater facilities. Based on the current site
topography, the site appears to drain stormwater run-off towards the west property line.
Streets Lake Ave S is a Residential Access Street with an existing right of way (ROW) width of 60.0-
ft as measured using the King County Assessor’s Map and approximately 24.0-ft of asphalt
paving.

DATE: October 30, 2025
TO: Pre-Application File No. PRE25-000314
FROM: Valerie Porter, 425-430-7288, vporter@rentonwa.gov
SUBJECT: Single-Family Home at Lake Ave S
1805 Lake Ave S, Renton, WA 98055
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 1805 Lake Ave S, Renton, WA (APN:
3340401115) and is 15,096 (0.35 acres) in size. The site is currently developed with an
existing single-family home and detached garage. The applicant is proposing to demolish the
existing structures and construct a new single-family home approximately 1,010 square feet
with an attached garage. The driveway providing primary access to the site will be relocated
to the south side of the site. According to City of Renton (COR) Maps, the subject parcel is
located within the Airport Influenced Area (Outer Approach/Departure Zone). The site is also
heavily impacted by the following geological hazard areas: regulated steep slopes (>15% &
<=90%), high erosion hazard area, high landslide hazard area, high seismic hazard area, and
moderate and high coal mine hazard areas.
Current Use: The site is currently developed with an existing single-family residence built in
1926 with a detached garage.
1. Zoning /Land Use Designation, and Overlays: The Comprehensive Plan designation for
the site is Residential Medium Density (RMD), and it is located within the Residential-6
(R-6) zoning designation. According to RMC 4-2-060, Uses Allowed in Zoning
Designations, a detached single family home is permitted uses within the R-6 zone.
2. Development Standards: The proposal is subject to RMC 4-2-110A, Development
Standards for Residential Low and Medium Density Zones – Primary Structures, effective
Single-Family Home at Lake Ave S

Applications\2025\PRE25-000314
at the time of complete application. Building elevations showing all facades shall be
provided with the permit application.
Density – The minimum density required in the R-6 zone is three (3) dwelling units per net
acre. The maximum density permitted is six (6) dwelling units per net acre. Net density is
calculated after the deduction of sensitive areas, areas intended for public right-of-way,
and private access easements. The minimum lot density for the site is 1 unit per net acre
(3 units x 0.35 acres = 1 units) and the maximum number of units allowed on the site is 2
units per net acre (6 units x 0.35 acres = 2 units).
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 required in the R-6 zone is
7,000 square feet for parcels being subdivided. The minimum lot depth is 90 feet and the
minimum lot width is 60 feet with the minimum lot width for corner lots is 70 feet. No
changes are proposed to the existing lot dimensions.
Setbacks – Setbacks are the minimum required distance between the building footprint
and the property line and any private access easement. The required setbacks in the R-6
zone are 25 feet for the front yard, 25 feet for the rear yard, and the side setbacks must
be a combined 15 feet with not less than 5 feet on either side. For corner lots the
minimum secondary front yard setback is 25 feet. As shown on the submitted site plan,
the proposed building appears to be outside of any required setback area. However,
building setbacks will be verified at the time of the building permit application.
Building Height and Impervious Surface Coverage – In the R-6 zone, the maximum wall
plate height is 24 feet, and the building may not exceed two stories. The proposal states
the building will be limited to 24 feet, which comply with building height requirements
outlined in RMC 4-2-110A, Development Standards for Residential Low Density and
Medium Density Zones – Primary Structures. 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.)
may 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 R-6 zone allows a maximum building coverage of 40% of the lot area and a maximum
impervious surface area of 55%. The proposal would result in an impervious surface
coverage of approximately 18%, which complies with the impervious surface
coverage permitted in the R-6 zone. The building height and coverage requirements
would be verified at the time of a formal application submission.
Maximum Number of Units per Building – Per RMC 4-2-110A, Development Standards for
Residential Low Density and Medium Density Zones – Primary Structures, a maximum of
four (4) attached dwelling units is allowed per building.

3. Residential Design and Open Space Standards: All new residences within the R-6 zone
are subject to the Residential Design Standards outlined in RMC 4-2-115, Residential
Design and Open Space Standards. Building elevations were not submitted for review.
Applications subject to the Residential Design and Open Space Standards must
demonstrate compliance with the applicable standards at the time of submittal.
4. Refuse and Recycling Areas: According to RMC 4-4-090, Refuse and Recyclables
Standards, residential developments must store refuse, recyclables, and compostable
carts either within a garage, accessory structure, or outside. If carts are located within a
garage, storage space must be appropriately sized to accommodate both vehicles and
carts for refuse, recyclables, and compostables. Storage space for carts must measure
at least two feet by six feet (2' x 6') floor area and sixty inches high. Indoor storage must
be clearly identified on floor plans. If carts are located outside, the storage space must
be at least two feet by six feet (2' x 6') in size and be located on the same lot as the
dwelling.
5. Landscaping: The proposal would be subject to the landscaping regulations in RMC 4-
4- 070, Landscaping. With the exception of critical areas, all areas of the site not covered
by structures, required parking, access, circulation or patios, must be landscaped. In
addition, 10 feet of on-site landscaping is required along all public street frontages, with
the exception of areas for required walkways and driveways.
If frontage improvements are required, street trees in the right-of-way planter would be
required. 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 & Spacing Guidelines. A
landscape plan shall be provided with the permit application as prepared by a
licensed Landscape Architect, a certified nurseryman or other certified
professional.
6. 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, Submittal Requirements – Specific to Application Type. 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, 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.

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.

Applications\2025\PRE25-000314
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 of a property. A
formal tree retention/planting plan and tree retention and tree credit worksheet
prepared by an arborist or landscape architect would be reviewed at the time of
formal application.
7. Fences/Retaining Walls: If the project includes fencing or retaining walls, their
locations must be clearly shown on the landscape plan and grading plan, including top
of wall and bottom of wall elevations. Any retaining wall that is four feet or taller
(measured from the footing to the top of the wall) will require a building permit. The
maximum allowable height for fences and retaining walls is 72 inches, subject to
additional height restrictions in setbacks and clear vision areas, as noted in RMC 4-4-
040D.
If the proposal includes a fence on top of a retaining wall, please ensure the total
combined height does not exceed the height limit for a standalone fence. The plans
should also consider screening requirements for any fenced yard areas and ensure an
adequate visual buffer. For additional information about fences and retaining walls,
please refer to retaining wall standards outlined under RMC 4-4-040.
8. Parking: The number of required parking spaces is based on the proposed land use per
RMC 4-4-080, Parking, Loading, and Driveway Regulations. According to the parking table
a detached single-family home is required to provide a minimum of two (2) parking stalls
per dwelling unit.
9. Access/Driveways: No driveway shall be constructed in such a manner as to be a hazard
to any existing street lighting standard, utility pole, traffic regulating device, fire hydrant,
abutting street traffic, or similar devices or conditions. Along the street frontage, the
maximum width of single-loaded garage driveways shall not exceed nine feet (9'), and the
maximum width of double-loaded garage driveways shall not exceed sixteen feet (16'). It
seems a double-loaded garage driveway is being proposed. The site plan shows a
driveway approximately 19’-6” wide, which exceeds the 16’ requirement.
RMC 4-4-080, Parking, Loading and Driveway Regulations, states,
maximum driveway slopes shall not exceed fifteen percent (15%); 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 entering
public or private streets, alleys, sidewalks, and/or pedestrian pathways. To exceed
fifteen percent (15%), a variance from the Administrator is required. Compliance with
access and driveway requirements would be verified at the time of the building
permit application.
Critical Areas: According to COR maps, the site contains regulated (steep) slopes (>15%
& <=90%), high erosion hazard area, high landslide hazard area, high seismic hazard
area, and moderate and high coal mine hazard area. It is the applicant’s responsibility
to determine whether any other critical areas are present on the site prior to formal
permit application.

Applications\2025\PRE25-000314
The provided site plan shows the lot being encumbered by protected slopes, where
development is prohibited. A portion of the rear deck is proposed within the building
setback buffer. RMC 4-3-050G, Development Standards, requires a building setback
buffer of 15 feet for protected slopes with only the following allowed in the building
setback buffer:
a. Landscaping;
b. Uncovered decks, less than eighteen inches (18") above grade;
c. Building overhangs, if such overhangs do not extend more than twenty four
inches (24") into the setback area; and
d. Impervious ground surfaces, such as driveways and patios.
As identified above, the deck may encroach into the buffer if it is less than eighteen
inches (18”) above grade. If the deck is greater than eighteen inches (18”) above
grade, the structure must be relocated outside of the building setback buffer or a
variance complying with the decision criteria listed under RMC 4-9-250 must be
requested.
Due to the presence of geological hazards, a geotechnical study shall be required at
the time of a formal application. All plans must show the location of the critical
areas and associated buffers on the site. In addition, 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. In addition, the study shall assess soil conditions
and detail construction measures to assure stability. Based upon the results of a
geotechnical report and/or independent review, conditions of approval for
developments may include buffers and/or setbacks from buffers.
Moderate coal mine hazards are areas where mine workings are deeper than two
hundred feet (200') for steeply dipping seams, or deeper than fifteen (15) times the
thickness of the seam or workings for gently dipping seams. These areas may be affected
by subsidence. High coalmine hazards are areas with abandoned and improperly sealed
mine openings and areas underlain by mine workings shallower than two hundred feet
(200') in depth for steeply dipping seams, or shallower than fifteen (15) times the
thickness of the seam or workings for gently dipping seams. These areas may be affected
by collapse or other subsidence. A coalmine study prepared by a qualified
professional shall be included with the application. The report shall review and
document any possible mine openings and potential trough subsidence, and any
known hazards previously documented or identified.
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.
10. Environmental Review: Critical area reports were not submitted to the city for review.
As a result, it is unclear if all critical areas impacting the site have been identified and
whether potential impacts to these areas have been adequately addressed. Per RMC 4-
9-070, Environmental Review Procedures, construction of one new single-family

residence on an existing legal lot is exempt from an Environmental (SEPA) Review, unless
the proposed development fails to comply with the Critical Area Regulations (RMC 4-3-
050), i.e. developing within a critical area or those projects requiring a variance or
reasonable use exception from RMC 4-3-050 or 4-3-090. In such case, an Environmental
(SEPA) Review is required.
11. Permit Requirements: If any critical areas are impacted, the proposal may require a
Critical Area Permit, a reasonable use variance permit, and Environmental (SEPA)
Review. Should the proposal be revised and no impacts to critical areas are proposed,
the proposed project will only require a building permit. If the project includes retaining
walls, fences, or outdoor storage areas, separate permits may also be needed. All land
use applications will be reviewed concurrently. The land use review would include public
notice and a two-week public comment period. Once a complete application is
submitted and all fees are paid, a decision can be issued in approximately 6-8 weeks.
The 2025 application fees are as follows: Critical Area Permit is $1,454, Variance Permit
is $1,536, and SEPA Review is $1,856, and 5% technology fee. Any modifications
requested would require an additional $299 fee.
When ready to apply for permits, contact the City of Renton Permit Services
at PermitTech@rentonwa.gov. All fees are subject to change. Detailed information
regarding the land use application submittal can be found on the City’s Permit Center
website. The city now requires electronic plan submittal for all applications.
Building Permits – New construction will require building permits. The project site is
located within Airport Influenced Area. According to RMC 4-3-020E, the applicant is
required to provide a certificate from an engineer or land surveyor clearly stating the
proposed use will not penetrate the Federal Aviation Administration Regulation Part
77 Objects Affecting Navigable Airspace. In addition, an avigation easement granted
to the City of Renton must be recorded and a description of construction and a
construction schedule with the building permit application to ensure proper notice
is provided to the responsible parties must be provide prior to approval of the
building permit.
Other Permits/Approvals – Additional permits may be required based on specific site
improvements, such as grading permits for significant site work, or right-of-way permits
if street improvements are needed. The applicant should ensure that all application
materials and required plans are submitted according to the City’s submittal
requirements, and compliance with permit conditions and mitigation measures will be
verified during the formal review process.
Detailed information regarding the land use permit application submittal requirements
can be found online under the Submittal Requirements documents. 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.

Manager if there are any questions regarding submittal requirements.
13. Public Information Sign: Public Information Signs are required for a 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. Planned urban
development projects require the applicant to install a public outreach sign per RMC 4-
8-120.
14. 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 2025 impact fees are as
follows:
• A Fire impact fee: $421.98;
• A transportation impact fee: $11,485.67;
• Renton School District Impact Fee: $1,003.00 (+5% administrative fee) unless an
