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 is proposing the development of ten (10) townhome units on two (2) parcels at 10945 and 11101 SE 168th St (APN 2923059057 and 2923059060). According to the King County Assessor, the subject parcels total approximately 60,456 sq. ft. (1.39 acres). The site is currently developed with two (2) existing single-family homes, one on each parcel, and associated accessory structures. As part of the proposal, all existing buildings would be demolished. The subject property is located within the Residential- 10 (R-10) zone and has a Comprehensive Plan land use designation of Residential High Density (RHD). Access to the development is proposed via a private drive off of SE 168th St. The proposal includes two (2) different options – one townhome version with 10 attached units in three (3) buildings, and one (1) detached condo version with seven (7) units. The onsite private driveway includes a hammerhead turnaround in both proposed options. An 8,358 sq. ft. open space tract is proposed southwest of the units in Site Plan Option A. According to City of Renton (COR) maps, no critical areas are present on the site, but a wetland is mapped on the parcel to the south (APN 863710TR-A) with a buffer potentially extending onto the subject site. In addition, the applicant’s pre-application submittal materials indicate the presence of a small Category III wetland near the southeast corner of the site. Current Use: The subject property is currently developed with two (2) existing single-family homes, one on each parcel, and associated accessory structures. 1. Zoning /Land Use Designation, and Overlays: The property is located within the Residential High Density (RHD) land use designation, the Residential-10 (R-10) zoning designation and within the Benson Community Planning Area. The Residential-10 Zone (R-10) is established for high-density residential development that will provide a mix of residential styles including small lot detached dwellings or attached dwellings such as townhouses and small-scale flats. Attached dwellings – townhouses are a CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre-Applications\2025\PRE25-000271 8 permitted use within the R-10 zone, subject to the standards of RMC 4-2-115, Residential Design and Open Space Standards, applicable to the R-10 and R-14 zones. Cottage housing – is a permitted use within the R-10 zone provided the cottage housing development complies with the standards of RMC 4-2-100G, Development Standards for Cottage House Development. A unit lot subdivision is intended to allow the creation of unit lots for cottage house development through established subdivision procedures while generally only applying development standards to the parent site as a whole rather than to individual unit lots. Unit lot subdivisions of nine (9) or fewer unit lots is processed as short subdivisions, and subject to all provisions of RMC 4-7-070, Detailed Procedures for Short Subdivisions. 2. Development Standards: The project is subject to RMC 4-2-110A, “Development Standards for Residential Zoning Designations” effective at the time of complete application (noted as “R-10 standards” herein). Density – The density range allowed in the R-10 zone is a minimum of 5.0 to a maximum of 10.0 dwelling units per net acre (du/ac). 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 gross site area is approximately 1.39 acres. Based on the gross site area of 1.39 acres, ten (10) dwelling units would result in a gross density of 7.2 du/ac (10 units / 1.39 = 7.2 du/ac). The proposed gross density of 7.2 du/ac would be within the density range permitted for the R -10 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 is no minimum lot size requirement in the R-10 zone for attached dwellings, however, the minimum lot size for detached dwellings is 4,000 square feet. The minimum lot depth is 70 feet for the R-10 zone. The minimum lot width is 40 feet for interior lots and 50 feet for corner lots. Submitted plans would need to show compliance with the required lot size and dimensional standard with the land use application. Setbacks – The R-10 zone requires a 20-foot (20’) minimum front yard setback except when all vehicle access is taken from an alley, then 15-feet (15’). A 15-foot rear yard setback and 4-foot (4’) side yard setback for detached units and attached units and 0 ft. for the attached side(s) are required. Setbacks are the minimum required distance between the building footprint and the property line and any private access easement or tract. In the R-10 zone to ensure adequate vehicular maneuvering area, garages and carports that are accessed through alleys shall be set back as follows: Nine-foot (9’) garage doors shall be at least 26 feet (26’) from the back edge of the alley or 16-foot (16’) garage doors shall be at least 24 feet (24’) from the back edge of the alley. Except for alley-accessed garages conforming to the previous requirements, the vehicle entry for a garage or carport shall be set back twenty feet (20') from the property line where vehicle access is provided; all other facades of a garage shall be subject to the applicable zone’s minimum setback. Submitted plans must comply with the required setbacks at the time of formal land use application. Building Standards – The R-10 standards allow a maximum building coverage of 55% of the lot area. The maximum impervious coverage in the R-10 zone is 70%. The maximum wall plate height is restricted to 24 feet. The townhouse buildings shall be no more than two (2) stories in height. 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 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre-Applications\2025\PRE25-000271 9 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. The maximum height for detached accessory structures is 12 feet and the total floor area must be less than that of the primary structure. Accessory structures are also included in building lot coverage calculations. Elevations were not provided with the pre-application submittal materials; building height and lot coverage requirements would be verified at the time of land use application. Maximum Number of Units per Building – No more than four (4) units per building. Cottage House Development Standards – Cottage house developments have specific development standards which can be found in RMC 4-2-110G. Cottage house units are limited to 1,500 sq. ft. in size. The minimum amount of cottages per cluster is 3 units, and the maximum amount is 12. All units must be detached, with a minimum separation of 8 ft. These requirement would be verified at the time of land use application. 3.
