DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: December 3, 2020 TO: Pre-Application File No. 20-000269 FROM: Jill Ding, Senior Planner SUBJECT: 162nd St Short Plat 11221 & 11233 SE 162nd St (Parcel Nos. 0088000132 & 0088000151) 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, 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 to subdivide two existing parcels into 8 residential lots, one lot/stormwater tract (Lot 3) and two shared driveway tracts (Tracts A and B). The subject property is located at 11221 and 11233 SE 162nd St (parcel nos. 0088000132 and 0088000151) along the south side of SE 162nd St. The project site totals 67,977 square feet (1.56 acres) in area and is currently developed with two single-family homes and associated detached accessory structures, proposed for removal. The site has a Comprehensive Plan Land Use of Designation of Residential Medium Density and a zoning designation of Residential-8 (R-8). The proposed lot sizes would range from 5,013 SF to 5,990 SF and the Lot 3/stormwater tract is proposed at 9,046 SF. Access to the proposed lots is proposed via a new dead end public street off of SE 162nd St, which terminates in a cul-de-sac turnaround. No critical areas are mapped on the project site. Current Use: The project site is currently developed with two single-family homes and associated detached accessory structures, which are proposed for removal. Zoning/Density Requirements: The subject property is located within the R-8 zoning classification. The density range allowed in the R-8 zone is a minimum of 4.0 to a maximum of 8.0 dwelling units per one net acre. The Residential Medium Density Land Use designation is intended to create opportunities for new single family residential neighborhoods and to facilitate high-quality infill development that promotes reinvestment in existing single family neighborhoods. Detached single family residential dwelling units are permitted uses within the R-8 zoning designation. The area of public and private streets (including driveway tracts and private access easements) and critical areas would be deducted from the gross site area to determine the “net” site area prior to calculating density. Using the 162nd St Short Plat Page 2 of 5 December 3, 2020 gross area of 67,977 square feet (1.56 acres), an 8-lot short plat arrives at a gross density of 5.13 du/ac (8 lots / 1.56 acres = 5.13 du/ac), which is within the permitted density range; however, the area of the shared driveway tracts and any public right-of-way dedication would need to be deducted to calculate net density. Calculations for minimum or maximum density which result in a fraction that is one-half (0.50) or greater shall be rounded up to the nearest whole number. Those density calculations resulting in a fraction that is less than one-half (0.50) shall be rounded down to the nearest whole number. A Density Worksheet would be required at the time of formal preliminary short plat application. The applicant would be required to demonstrate compliance with the net density requirements of the zone at the time of formal 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-8 standards” herein). Building Standards – The R-8 standards allow a maximum building coverage of 50% of the lot area. The maximum impervious coverage in the R-8 zone is 65%. The maximum wall plate height is restricted to 24 feet, and the buildings shall be not 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. Compliance with the building standards for the new single-family residences would be reviewed at the time of building permit review. Setbacks – Setbacks are the minimum required distance between the building footprint and the property line. The required setbacks for the R-8 zone are: Front yard: 20 feet for the primary structure, except when all vehicle access is taken from an alley, then 15 ft ; Rear yard: 20 feet; Side yards: 5 feet; and Secondary Front yard: 15 feet. 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. Please note that lots with frontage on both a public street and a shared driveway are classified as corner lots and therefore are subject to corner lot yard standards. Compliance with the setbacks for the proposed new single-family homes will be verified at the time of building permit review. Access/Driveways/Parking: Access to the proposed lots is proposed via a new dead end public street off of SE 162nd St, access to Lot 1 and 2 would be provided via Shared Driveway Tract A and access to Lots 5 and 6 would be provided via a Shared Driveway Tract B. 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; 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 sufficient access for emergency vehicles and personnel. 162nd St Short Plat Page 3 of 5 December 3, 2020 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 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 driveway standards would be verified at the time of building permit review. Each lot is required to accommodate off street parking for a minimum of two vehicles with one additional space required for the Accessory dwelling unit. Fences/Walls: If the applicant intends to install any fences or retaining walls as part of this project, the location must be designated on the landscape plan or grading plan. A fence and/or wall detail should also be included on the plan. A retaining wall that is 4 feet or taller, as measured by the vertical distance from the bottom of the footing to the finish grade at the top of the wall requires a building permit. 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. For more information about fences and retaining walls refer to RMC 4-4- 040. 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 or other certified professional. Significant Tree Retention: If significant trees are proposed to be removed, a tree inventory and a tree retention 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% of existing significant trees, the lot would be required to provide a minimum tree density of 2 trees per 5,000 square feet of lot area onsite. 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. 162nd St Short Plat Page 4 of 5 December 3, 2020 The Administrator may require independent review of any land use application that involves tree removal and land clearing at the City's discretion. If staff determines that the trees cannot be retained, replacement trees, with at least a 2-inch caliper or an evergreen at least 6 feet tall, shall be planted at a rate of 12 caliper inches of new trees to replace each protected tree removed. A formal tree retention plan prepared by an arborist or landscape architect would be reviewed at the time of the formal land use application if any trees are proposed for removal. Residential Design and Open Space Standards: All single family residences would be subject to the Residential Design Standards for the R-8 zone, outlined in RMC 4-2-115. Residential Design Review occurs as part of the Building Permit Review. Critical Areas: According to COR Maps, no critical areas are mapped on the project site. 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. Environmental Review: Subdivisions of 9 or fewer residential lots is exempt from Environmental (SEPA) Review. Permit Requirements: The proposal would require administrative short plat approval. The 2021 administrative short plat application fee is $5,680 ($5,410 plus a 5% Technology Surcharge Fee). Any modifications requested would be an additional $273 ($260 plus a 5% Technology Surcharge Fee). All fees are subject to change.
