1. In accordance with RMC 4-6-060, if the site improvements and/or proposed building additions exceed
an overall valuation of $175,000, the project site(s) shall be required to meet the City’s Complete
Streets Standards: The proposed project fronts Williams Ave S to the west, and an alley to the east.
• Williams Ave S. is classified as Minor Arterial with an existing right of way (ROW) width of 60’
as measured using the King County Assessor’s Map with an existing paved width of
approximately 42 feet. Per RMC 4-6-060, to meet the City’s complete street standards for
Minor Arterial streets, a minimum ROW width of 91 feet is required, half of street
improvements as taken from the ROW centerline would be required and include a 54 feet
paved road (27 feet each side), a 0.5-foot curb, an 8-foot planting strip, an 8-foot sidewalk,
street trees and storm drainage improvements. Dedication of approximately 15.5 feet would
be required.
i. However, the COR transportation department has determined that the existing
curb-curb width is sufficient, and a modified minor arterial street standard
containing a right of way width of approximately 67-feet is acceptable. The modified
street would contain 12-foot sidewalks with 0.5-foot curb with street trees in tree
grates on both sides of the street. Therefore, frontage improvements including a full
width of the 12-foot sidewalk, 0.5-foot curb with street trees in tree grates are
required, and right-of-way dedication of approximately 3.5-feet based on final
survey would be required for this project. A modification shall be submitted with
the land use application for the listed section.
• An alley to the east of the property with an existing ROW width of approximately 10-feet
and an existing paved width of approximately 10 feet. Per RMC 4-6-060, the minimum right
of way width for an alley is 16-feet; therefore, a dedication of 3-feet of right of way will be
required depending on the final survey. Per City code 4-6-060 the alley would need to be 12-
feet paved with storm drainage improvements.
2. Refer to City code 4-4-080 regarding driveway regulations.
3. Undergrounding of all existing and proposed utilities is required on all frontages per RMC 4-6-090.

required to do a traffic impact analysis. The trips should be calculated based on the guidelines of the
current ITE Trip Generation Manual. Refer to the attached policy guidelines for traffic impact analysis
for guidelines. If the site generates 20 or more new peak hour trips in either AM peak or PM peak,
then applicant should contact the City to get information of the locations where traffic analysis is
required.
7. Paving and trench restoration within the City of Renton right of way shall comply with the City’s Trench
Restoration and Street Overlay Requirements.
8. The development is subject to transportation impact fees. Fees will be charged based on the rate at
the time of building permit issuance.

M E M O R A N D U M
DATE: September 26, 2024
TO: Pre-Application File No. 24-000253
FROM: Jill Ding, Senior Planner
SUBJECT: 410 Williams Ave S – 410 Williams Ave S (APN 7231501625)
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 on the east side of Williams Ave S and south of
S 4th St and is addressed as 410 Williams Ave S (APN 7231501625). The project site totals 11,500
square feet (0.26 acres) in area and is zoned Center Downtown (CD), downtown business district,
and is within Urban Design District A. The project site is currently developed with an existing 2,930
square foot single-family residence, currently used as an office building. The existing building is
proposed to be removed. The applicant proposes to construct a new four-story building with
twenty-four (24) residential units, and either two live-work units or 3,829 square feet of retail on
the ground floor. Parking would be provided within the building and would include 24-25 spaces.
According to City of Renton (COR) Maps, the site is mapped within a seismic hazard area and
within a wellhead protection area, zone 1.
Current Use: Currently the site is occupied with an existing single-family residence, currently
utilized as an office building. The exiting structure would be removed.
1. Zoning /Land Use Designation, and Overlays: The property is located within the Commercial
Mixed Use (CMU) land use designation, the Center Downtown (CD) zoning designation, and
Urban Design District A. Commercial & Mixed Use designations are place areas with
established commercial and office areas near principle arterials. Residential uses are allowed
as part of mixed-use developments, and support new office and commercial development
that is more intensive than what exists to create a vibrant district and increase employment
opportunities. The intention of this designation is to transform strip commercial development
into business districts through the intensification of uses and with cohesive site planning,
landscaping, signage, circulation, parking, and the provision of public amenity features. The
410 Williams Ave S
Page 2 of 11
September 26, 2024
purpose of the Center Downtown Zone (CD) is to provide a mixed-use urban commercial
center serving a regional market as well as high-density residential development. Uses include
a wide variety of retail sales, services, multi-family residential dwellings, and recreation and
entertainment uses.
Attached residential units are permitted within the CD zone, provided the dwelling units shall
be integrated into a vertically mixed-use building with ground floor commercial situated
closest to a public street. Commercial uses in residential mixed-use developments are limited
to retail sales, on-site services, eating and drinking establishments, taverns, daycares,
preschools, indoor recreational facilities, pet daycares, craft distilleries/small wineries/micro-
breweries with tasting rooms, general offices not located on the ground floor, and similar uses
as determined by the Administrator. The proposal including live-work units on the ground
floor would not be permitted as live-work units are not included in the acceptable
commercial uses listed above and are not uses permitted within the CD zone. Retail uses are
permitted uses within the CD zone.
Uses normal and incidental to a building including, but not limited to, interior entrance areas,
elevators, waiting/lobby areas, mechanical rooms, mail areas, garbage/recycling/compost
storage areas, vehicle parking areas, and areas/facilities for the exclusive use of the residents
are not considered commercial uses.
2. Development Standards: The project would be subject to RMC 4-2-120B, “Development
Standards for Commercial Zoning Designations” effective at the time of complete application
(noted as “CD standards” herein).
Density – The area of public rights-of-way, legally recorded private access easements and
critical areas (such as protected slopes, Class 1 to 4 streams, etc.) 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 density range permitted in the CD zone is a minimum of 75 dwelling units
per net acre up to a maximum of 150 dwelling units per net acre. The maximum density may
be increased up to a maximum of 200 dwelling units per net acre with the approval of a
Conditional Use Permit. A density bonus may be granted for developments that satisfy the
criteria and standards of RMC 4-9-065, Density Bonus Review. Based on a gross site area of
0.26 acres, the proposal for 24 dwelling units would result in a gross density of 92 dwelling
units per acre, which is within the density range permitted within the CD zone. 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 – There are no minimum lot size, width and depth
requirements in the CD.
Setbacks – Setbacks are the distance between the building and the property line or any private
access easement or tract. Setback requirements in the CD zone are as follows:

Design – For vertically mixed-use buildings, the facade necessary for interior entrances,
lobbies, and areas/facilities developed for the exclusive use of the building’s residents, or
their guests (“lobby facade” for the purposes of this Section), is limited to thirty five percent
(35%) of the overall facade along any street frontage or the primary facade. The Administrator
may allow the lobby facade to exceed thirty five percent (35%) if the depth of the commercial
space exceeds the minimum required by RMC 4-4-150E, provided the increased percentage
of lobby facade is generally proportional to the increased depth of commercial space.
Ground Floor Commercial – Where Required – A vertically mixed-use building with at least
two (2) residential stories above ground floor commercial is required within the CD Zone
within the Downtown Business District.
Commercial Area Requirement – Within the following zones, any development wherein
dwelling units are proposed shall provide an amount of gross commercial floor area
equivalent to a percentage of the building footprint(s) of all buildings on site containing
residential dwelling units, as specified in the chart below. The following areas are exempt
from commercial space requirements: CD-zoned properties outside of the Downtown
Business District; and CV-zoned properties not abutting NE Sunset Blvd. east of Harrington
Avenue NE.
CN CV CA CD CO COR UC-1 UC-2
40% 40% 40% 50% 40% 40% 40% 20%
Ground Floor Commercial Space Standards – At a minimum, the development shall include
ground floor commercial space along any street frontage or, in the absence of street frontage,
along the primary facade of the building in conformance with the following standards:
a. A minimum average depth of thirty feet (30') and no less than twenty feet (20') at any given
point;
b. A minimum floor-to-ceiling height of eighteen feet (18'), and a minimum clear height of
fifteen feet (15') unless a lesser clear height is approved by the Administrator;
c. ADA compliant bathrooms (common facilities are acceptable);
d. A central plumbing drain line; and
e. A grease trap and a ventilation shaft for a commercial kitchen hood/exhaust.
The proposal would be required to demonstrate compliance with the above requirements
at the time of formal land use application. Based on the materials submitted, it does not
appear that the proposal included the required 50% ground floor commercial area.
4. Refuse and Recycling Areas: Refuse and recycling areas must meet the requirements of RMC
4-4-090, “Refuse and Recyclables Standards.”
In residential developments, a minimum of one and one-half (1-1/2) square feet per dwelling

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 credit worksheet
prepared by an arborist or landscape architect would be required if the proposal includes
any expansion or addition of the existing building.
7. Fences/Retaining Walls: If the applicant intends to install any fences as part of this project,
the location must be designated on the landscape plan. A wall taller than four feet requires a
building permit. Fences up to six-feet in height are permitted in the rear yard and side yard;
fences up to four feet are permitted in the front yard. Any part of a yard that is within a clear
vision area has a limited fence height of 42 inches. 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. New or existing fencing would need to
comply with the fence requirements of the code (RMC 4-4-040).

11. Critical Areas: The project site is mapped within a seismic hazard area and within wellhead
protection area, zone 1. A high seismic hazard area is mapped on the project site. The
applicant may be required to provide a geotechnical report demonstrating the proposal
would not increase the threat of the geological hazard to adjacent or abutting properties
beyond pre-development conditions; 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 application.
12. Environmental Review: The proposal would be subject to Environmental (SEPA) Review in
accordance with WAC 197-11-800 as the proposal includes the construction of a new mixed-
use building with more than nine (9) residential dwelling units.
13. Site Plan Review: Per RMC 4-9-200, site plan review is required for any development in the
CD zone. The purpose of the site plan review process is to analyze the detailed arrangement
of project elements to mitigate negative impacts where necessary to ensure project
compatibility with the physical characteristics of a site and with the surrounding area. Site
plan review ensures quality development consistent with City goals and policies. Site plan
review analyzes elements including, but not limited to, site layout, building orientation and
design, pedestrian and vehicular environment, landscaping, natural features of the site,
410 Williams Ave S

screening and buffering, parking and loading facilities, and illumination to ensure
compatibility with potential future development. Decisional criteria for site plan approval are
itemized in RMC 4-9-200.E.3.
14. Permit Requirements: The proposed project would require an Administrative Site Plan
Review and Environmental (SEPA) Review. The applications would be processed concurrently
within an estimated time frame of 6-8 weeks. The 2024 application fees would total $5,071.50
($3,030 Site Plan + $1,800 SEPA + $241.50 technology = $5,071.50). 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 application submittal can be found on the City’s
Permit Center website. The City now requires electronic plan submittal for all applications.
Please refer to the City’s Electronic File Standards.
In addition to the required land use permits, separate construction and building permits
would be required.
15. Waivers of Submittal Requirements: The submittal checklist is not an exhaustive list of
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.
16. 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.
