DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: August 12, 2021 TO: Pre-Application File No. PRE21-000274 FROM: Brittany Gillia, Assistant Planner SUBJECT: Bach Development 1717 Davis Ave S (Parcel No. 3340401295) 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 applicant is proposing to subdivide one (1) existing single family parcel into two (2) lots. The project site (Tax Parcel 3340401295) is located at 1717 Davis Ave S and totals approximately 14,700 sq. ft. (0.34 acres) in area and is zoned Residential-6 (R-6). The existing single family residence is proposed to remain on proposed Lot B and reduced in size to accommodate a shared driveway off of Davis Ave S. Proposed Lot A would have an area of 7,350 sq. ft. and would access off Davis Ave S via a proposed 12’ wide shared driveway. Proposed Lot B would have an area of 7,350 sq. ft. and would have access via a remaining portion of the existing driveway leading to Davis Ave S. The site is mapped with a High Landslide Hazard and Sensitive Slopes. Current Use: The property is developed with an existing single family home that is proposed to be reduced in size. 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. The proposal for 2 lots on the 0.34 acre gross site area would Bach Development, PRE21-000274 Page 2 of 5 August 12, 2021 result in a gross density of 5.93 dwelling units per acre (2 lots / 0.34 acres = 5.93 du/ac). The applicant would be required to submit a density worksheet demonstrating compliance with net density at the time of formal land use application. 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 subdivided parcels that are less than one acre, one of the lots is 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 lots would provide adequate area for compliance with the minimum area required, however Lot B would not provide the minimum lot width of 70 feet as it meets the definition of a corner lot abutting Davis Ave S and the shared driveway. 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 structu res are also included in building lot coverage calculations. The proposal’s compliance with the building standards for the new homes 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 yard 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. The applicant is proposing to reduce the size of the existing home to accommodate a shared driveway tract. The proposal does not meet the minimum setback requirement of 25 feet for the yard space between the structure and the shared driveway tract. 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 proposed Lot A would be provided via a 12’ shared driveway leading to Davis Ave S. Access to proposed Lot B would be provided via an existing driveway off of Davis Ave S. Shared driveways may be allowed for access to four (4) or fewer residential lots, provided: a. At least one of the four (4) lots abuts a public right-of-way and the street frontage of the lot is equal to or greater than the lot width requirement of the zone; Bach Development, PRE21-000274 Page 3 of 5 August 12, 2021 b. The subject lots are not created by a subdivision of ten (10) or more lots; c. A public street is not anticipated by the City of Renton to be necessary for existing or future traffic and/or pedestrian circulation through the short subdivision or to serve adjacent property; d. The shared driveway would not adversely affect future circulation to neighboring properties; e. The shared driveway is no more than three hundred feet (300') in length; and f. The shared driveway poses no safety risk and provides suff icient access for emergency vehicles and personnel. Shared driveways shall be within a tract; the width of the tract and paved surface shall be a minimum of sixteen feet (16'); the Fire Department may require the tract and paved surface to be up to twenty feet (20') wide. If a shared driveway abuts properties that are not part of the subdivision, an eight foot (8') wide landscaped strip shall be provided between the shared driveway and neighboring properties. The landscape strip shall be within a tract and planted with a mixture of trees, shrubs, and groundcover. The shared driveway may be required to include a turnaround per subsection H of RMC 4-6-060. The maximum grade for the shared driveway shall not exceed fifteen percent (15%), except for within approved hillside subdivisions. The proposed shared driveway does not meet minimum width standards for paved surface and landscape strip. Parking: Each lot is required to accommodate off-street parking for a minimum of two vehicles. Compliance with parking regulations would be verified 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. 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 Bach Development, PRE21-000274 Page 4 of 5 August 12, 2021 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: The site is mapped within a High Landslide Hazard and Sensitive Slope designation. A geotechnical soils report will be required at the time of formal land use application. Environmental Review: Short plats are categorically exempt from Environmental (SEPA) Review except for lands covered by water or critical areas as designated in RMC 4-9-070H.2. The proposed short plat would no longer be exempt from environmental review if further investigation of the site results in the identification of designated critical areas. Permit Requirements: The subdivision of fewer than 10 lots requires a Short Plat application. The application review is administrative and would be processed within an estimated time frame of six to eight weeks. The 2021 administrative short plat application fee is $5,680.50 ($5,410.00 each plus a 5% Technology Surcharge Fee). Each modification request is $262.50 ($250.00 each plus a 5% Technology Surcharge Fee). All fees are subject to change. A Short Plat Submittal Requirements Checklist is linked here.
