DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: December 16, 2021 TO: Pre-Application File No. 21-000438 FROM: Jill Ding, Senior Planner SUBJECT: Westview Short Plat 54X S 55th St Parcel No. 3123059119 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 subject property is rectangularly shaped and is located on the north side of S 55th St at 54X S 55th St (parcel no. 3123059119). The applicant is proposing to subdivide the existing, vacant, 98,010 sq. ft. (2.25 acre) site into 6 lots, a shared driveway tract, and an open space tract. There are two residential zoning designations mapped on the project site, approximately 46,000 sq. ft. of the site is located within the Residential – 4 (R-4) zone and approximately 52,000 sq. ft. is located within the Residential – 1 (R-1) zone. The portion of the project site located within the R-1 zone is also mapped within the Talbot Urban Separator Overlay. Access to the proposed lots is proposed via a 20-foot wide shared driveway off of S 55th St. High and moderate landslide hazard areas and sensitive and protected slopes are mapped on the project site. Current Use: The site is currently vacant. Zoning/Density Requirements: There is no minimum density requirement within the R-1 and R-4 zones. The maximum density permitted for R-1 zoned properties within the Urban Separator Overlay is 1 dwelling unit per gross acre (RMC 4-2-110E.36) subject to the requirements of RMC 4-3-110, Urban Separator Overlay Regulations. The maximum density permitted in the R-4 zone is 4.0 dwelling units per net acre (du/ac). Net density is calculated after the deduction of areas required for public right-of-way dedication, shared driveway tract, and critical areas from the gross site area. A density worksheet was not included with the pre-application submittal materials; therefore staff was unable to verify compliance with the density requirements. The applicant would be required to submit a density Westview Short Plat, PRE21-000438 Page 2 of 6 December 16, 2021 worksheet for each zoning designation mapped on the project site, verifying that the proposed lots would comply with the density requirements of the R-1 and R-4 zones. 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-1 and R-4 standards” herein). Minimum Lot Size, Width and Depth – The minimum lot size permitted in the R-1 zone is one acre. Minimum lot width is 100 feet for interior lots and 110 feet for corner lots; the minimum lot depth required is 200 feet. W ithin designated urban separators, clustering is required; individual lots shall not be less than ten thousand (10,000) square feet and development shall be consistent with RMC 4-3-110, Urban Separator Overlay Regulations. Outside of designated urban separators, clustering may be allowed in order to meet objectives such as preserving significant natural features, providing neighborhood open space, or facilitating the provision of sewer service. The maximum net density shall not be exceeded; except within urban separators a density bonus may be granted allowing the total density to achieve one dwelling unit per gross contiguous acre. In order for the bonus to be allowed, projects must provide native vegetation cover (either existing or new) on sixty five percent (65%) of the gross area of all parcels in the land use action, including both the area within and outside the open space corridor. In addition, projects shall provide at least one of the following: a. Enhancement of wetlands at a ratio of one-half (1/2) acre enhanced for one acre delineated within the urban separator pursuant to RMC 4-3-050M12b, Evaluation Criteria, and RMC 4-3-050M12c, Wetlands Chosen for Enhancement. Enhancement proposed for a density bonus may not also be used for a mitigation for other wetland alterations; or b. The removal of and/or bringing into conformance with Renton standards of legal nonconforming uses from the site; or c. Natural surface pedestrian trails with public access. The trails can be part of an adopted trail system or, where there is no planned trail system, of a configuration approved by the Community and Economic Development Administrator. In the absence of either wetlands or legal nonconforming uses on the site, public access and trails shall be provided and approved by the Community and Economic Development Administrator. The minimum lot size permitted in the R-4 zone, is 9,000 square feet for parcels being subdivided. Minimum lot width is 70 feet for interior lots and 80 feet for corner lots; minimum lot depth is 100 feet. The applicant would be required to provide a lot layout during the application prescreening process and prior to the City formally accepting the application that demonstrates all lots would comply with the minimum lot size, width, and depth requirements of the R-1 and R-4 zones as well as the Urban Separator Regulations. Building Standards – The R-1 standards allow a maximum building coverage of 20% of the lot area. The maximum impervious surface coverage in the R-1 zone is 25%. The R-4 standards allow a maximum building coverage of 35% of the lot area. The maximum impervious coverage in the R-4 zone is 50%. The maximum wall plate height permitted in the R-1 and R-4 zones is restricted to 32 feet, and the buildings shall be not more than three 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 must remain below a height of 15 feet. The gross floor area must be less than that of the primary structure. Accessory structures are also included in building lot coverage calculations. Compliance with the building standards for the new building would be required to be demonstrated at the time of building permit review. Westview Short Plat, PRE21-000438 Page 3 of 6 December 16, 2021 Setbacks – Setbacks are the minimum required distance between the building footprint and the property line. The required setbacks for the R-1 zone are: Front yard: 30 feet for the primary structure; Rear yard: 30 feet; Side yards: 15 feet; and Secondary Front yard: 30 feet. The required setbacks for the R-4 zone are: Front yard: 30 feet for the primary structure; Rear yard: 25 feet; Side yards: 20 feet combined (minimum of 7.5 feet on either side); and Secondary Front yard: 30 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. Setbacks for the new residences would be verified at the time of building permit review. Access/Parking: Access to the proposed lots is proposed via a 20 ft. wide shared driveway off of S 55th St. 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. 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, as required in RMC 4-4-070. The shared driveway may be required to include a turnaround. No sidewalks are required for shared driveways; however, drainage improvements pursuant to City Code are required (i.e., collection and treatment of stormwater), as well as an approved pavement thickness. The maximum grade for the shared driveway shall not exceed fifteen percent (15%), except for within approved hillside subdivisions. Any driveway shall be setback at least 5 feet from the side lot lines (unless utilizing a joint driveway). The proposal to access six lots off the shared driveway tract exceeds the maximum number of lots (4) permitted to access from a shared driveway. The proposed layout would need to be revised to comply with the shared driveway standards. Each lot is required to accommodate off street parking for a minimum of two vehicles. The maximum driveway slopes cannot exceed 15%. If the grade exceeds 15%, a variance is required. Driveways exceeding eight percent (8%) shall provide slotted drains at the lower end with positive drainage discharge to restrict runoff from entering the garage/residence or crossing any public sidewalk. Compliance with private driveway standards would be verified at the time of building permit review. 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 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. 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. Urban Separator Overlay: The project site is mapped within the Talbot Urban Separator Overlay. Approval of a short plat on an undeveloped legal lot in the Talbot Urban Separator Overlay shall require dedication of fifty percent (50%) of the gross land area of that portion of the parcel or parcels located within the Urban Separator as a non-revocable open space tract retained by the property owner, or dedicated to a homeowners association or other suitable organization as determined by the Administrator. In order to satisfy the dedication requirement, some of the area to be dedicated may consist of land abutting the Urban Separator, as determined by the Community and Economic Development Administrator, on a case-by-case basis. Acreage in tracts may include critical areas and/or critical area buffers. At a minimum, open space shall be connected to another contiguous open space parcel by a fifty foot (50') corridor. Forest/vegetation clearing shall be limited to a maximum of thirty five percent (35%) of the gross acreage of the site except: i. The percentage of forest/vegetation coverage may be increased to qualify for the density bonus allowed in RMC 4-2-110E. Westview Short Plat, PRE21-000438 Page 5 of 6 December 16, 2021 ii. Modification of the percentage of forest/vegetation retention may be approved if determined necessary to meet the surface water retention/detention standards of RMC 4-3-110E5d of this Section. iii. Forest/vegetation clearing greater than thirty five percent (35%) of individual building sites may be approved to allow grading for a home site; provided, that: (a) A landscape plan is provided for each building site showing compensating replanting of species with the same or better water retention and erosion control functions; (b) Five percent (5%) additional replacement landscaping per site is provided; (c) Plant caliper is sufficient to achieve needed water retention and erosion control functions; (d) Individual trees or stands of trees are retained when feasible. Feasibility is defined as locations and tree health sufficient to ensure continued viability of the tree and safety of structures within the developed portion of the lot; and (e) The landscape plan provides massing of plant material to create either a connection to required open space or is of sufficient size to create functional wildlife habitat. b. If the existing cleared area of a site, as of March 21, 2005, is greater than thirty five percent (35%), approval of a plat shall require replanting of forest/vegetative cover. c. Forest/vegetation cover may include a combination of Northwest native vegetation including conifer, deciduous trees and shrubs sufficient to provide water retention and erosion control. If existing vegetation is found to be insufficient to meet forest/vegetation coverage standards, additional plantings shall be required. d. Stormwater management shall comply with the Surface Water Design Manual. e. Private access easements and improvements shall be established at the minimum standard needed to meet public safety requirements. f. Landscape plans required in RMC 4-4-070 shall include retention/replanting plans as applicable, consistent with standards and plant lists in King County Department of Natural Resources and Parks Water and Land Resources Division Publication “Going Native.” Critical Areas: High and moderate landslide hazard areas and sensitive and protected slopes (grades between 25 and 90 percent) are mapped on the project site. A 15-foot structure setback is required for protected slopes. In addition, protected slopes and their associated buffers shall be placed in a Native Growth Projection Area (tract). A geotechnical report would be required at the time of formal land use application. Hillside Subdivisions: The following additional standards shall apply to hillside subdivisions: 1. Application Information: Information concerning the soils, geology, drainage patterns, and vegetation shall be presented in order to evaluate the drainage, erosion control and slope stability for site development of the proposed plat. The applicant must demonstrate that the development of the hillside subdivision will not result in soil erosion and sedimentation, landslide, slippage, excess surface water runoff, increased costs of building and maintaining roads and public facilities and increased need for emergency relief and rescue operations. 2. Grading: Detailed plans for any proposed cut and fill operations shall be submitted. These plans shall include the angle of slope, contours, compaction, and retaining walls. Plans shall be consistent with requirements in RMC 4-4-060, Grading, Excavation and Mining Regulations. 3. Tracts: Areas of the subdivision deemed to be critical areas due to designation as protected slopes shall be located within a tract or tracts. 4. Streets: Westview Short Plat, PRE21-000438 Page 6 of 6 December 16, 2021 a. Streets may only have a grade exceeding fifteen percent (15%) if approved by the Department and the Fire Department. b. Street widths may be less than those required in the street standards for streets with grades steeper than fifteen percent (15%) if parking prohibition on one or both sides of the street is approved by the Administrator. ) 5. Lots: Lots may be required to be larger than minimum lot sizes required by the Zoning Code. Generally, lots in steeper areas of the subdivision should be larger than those in less steep areas of the subdivision. 6. Erosion Control Requirements: Any clearing or grading shall be accompanied by erosion control measures as deemed necessary by the Department. Environmental Review: Projects with critical areas are subject to Environmental (SEPA) Review (RMC 4-9- 070H.2). An environmental checklist would be required with the short plat application. An environmental threshold determination would be issued by the City’s Environmental Review Committee. Permit Requirements: The proposal would require administrative Short Plat approval and Environmental (SEPA) Review. However please be advised that if there are sufficient concerns by the residents in the area of the short plat, or by City staff to warrant a public hearing, then the short plat may be referred to the Hearing Examiner for public hearing and decision. The applications would be reviewed concurrently within an estimated time frame of six to eight weeks. The 2022 administrative application fees would total $7,360.50 ($5,410.00 short plat + $1,600.00 SEPA + $350.50 Technology Fee = $7,360.50). Each modification request is $262.50 ($250.00 each plus a 5% Technology Surcharge Fee). All fees are subject to change.
