DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: July 9, 2020 TO: Pre-Application File No. PRE20-000133 FROM: Jill Ding, Senior Planner SUBJECT: Mangat Short Plat 1415 N 24th St 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 www.rentonwa.gov Project Proposal: The project site (Tax Parcel 334450-0234) is located at 1415 N 24th St and totals approximately 23,595 square feet (0.54 acres) in area and is zoned Residential-6 (R-6). An existing single family residence is proposed to be removed. The proposal is to subdivide the existing parcel into 2 legal lots. Proposed Lot 1 would have an area of 11,221 sq. ft. and Lot 2 would have an area of 11,087 sq. ft. Access to the proposed lots would be provided via individual driveways off of N 24th St. The site is mapped within a Wellhead Protection Area, zone 2. Current Use: The property is developed with an existing single family home, proposed for removal. 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 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 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. After the deduction of 1,043 sq. ft. for public right-of-way dedication from the 23,595 sq. ft. gross site area, the project site would have a net area of 22,552 sq. ft. (0.52 acres). The proposal for 2 lots on the 0.52 net acre site would Mangat Short Plat Preapplication Meeting July 9, 2020 result in a net density of 2/0.52=3.85 du/ac, which is within the density range permitted in the R-6 zone. 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 parcels less than one acre, with one lot allowed to be smaller than the required minimum lot size. This single lot is allowed to be 6,250 square feet in Zone R-6. Minimum lot width is 60 feet for interior lots, or 70 feet for corner lots. Minimum lot depth is 90 feet. The proposed lot configuration appears to be compliant with minimum lot dimensional standards of the R-6 zone. 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 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 y ard 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. Setback compliance for the new homes would be verified at the time of building permit review. 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. Access: Access to the proposed lots would be provided residential driveways off N 24th St. Parking: Each lot is required to accommodate off-street parking for a minimum of two vehicles. The existing home appears to comply with the off-street parking standard. The proposal’s compliance with the building standards for the new home would be verifi ed 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. Access to the proposed lots Mangat Short Plat Preapplication Meeting July 9, 2020 would be provided via single family residential driveways. Compliance with the driveway regulations would be verified at the time of formal land use review. 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. 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: A Tree Retention/ Land Clearing (Tree Inventory) 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 30 percent (30 %) of significant trees, and indicate how proposed building footprints would be sited to accommodate preservation of significant trees that would be retained. 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. In addition to retaining 30 percent of existing significant trees, each new lot would be required to provide a minimum tree density of 2 trees per 5,000 square feet of lot area onsite. Protected trees that do not contribute to a lot's required minimum tree density shall be held in perpetuity within a tree protection tract. 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; and Significant trees over sixty feet (60') in height or greater than eighteen inches ( 18") caliper. 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. Critical Areas: A Wellhead Protection Area, zone 2 is mapped on the project site. A fill source statement would be required if fill is brought onto the project site. Environmental Review: The proposed project is categorically exempt from Environmental (SEPA) Review. Permit Requirements: The proposal would require administrative short plat approval.
