PRE24-000256_PlanningComments_240908 Department of Community & Economic Development Memorandum DATE: September 26, 2024 TO: Pre-Application File No. 24-000256 FROM: Mariah Kerrihard, Assistant Planner SUBJECT: Serduk Short Plat – 3500 Park Ave N 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, 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 proposes to subdivide 3500 Park Ave N (APN 3342103170) into two (2) residential lots for the benefit of detached dwellings. The property has street frontage along Park Avenue N and is located within the Residential-6 (R-6) zone. The site area is approximately 13,650 square feet (0.31 acre). Access is proposed via a private access easement from Park Avenue N. There are sensitive slopes mapped on the property per City of Renton (COR) maps. Current Use: The project area is currently developed with a 1,450 square foot single family dwelling. Access to the detached dwelling is from Park Avenue N. The existing dwelling is proposed to be retained on Lot 2. 1. Zoning /Land Use Designation, and Overlays: The subject property is located within the Residential-6 (R-6) zoning classification. The Residential Medium Density Land Use designation is intended to implement the R-6 zone. The R-6 zone is established for single family dwellings. Development in the R-6 zone is intended to be single family residential at moderate density. Detached dwellings are permitted within the R-6 zone and one (1) ADU is permitted per legal lot.1 1 “Missing middle” house bills for housing (E2SHB 1110) and accessory dwelling units (EHB 1337). Serduk Short Plat Page 2 of 7 September 25, 2024 PRE24-000256_PlanningComments_240908 2. 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). Density – The area of public rights-of-way, legally recorded private access easements and critical areas (i.e., very high landslide hazard areas, protected slopes (except evaluate on a case-by-case basis those protected slopes created by previous development, wetlands, Class 1 to 4 streams and lakes or floodways)) 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 R-6 zone has a minimum density of three (3) dwelling units per acre with a maximum of six (6) dwelling units per acre. A density worksheet was not included with the pre-application submittal materials; therefore, staff was unable to verify compliance with the density requirements. 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 – The minimum lot size permitted in the R-6 zone is 7,000 square feet for parcels being subdivided. Minimum lot width is 60 feet (60’); minimum lot depth is 90 feet (90’); minimum lot width for corner lots is 70 feet (70’). For short plats of parcels smaller than one (1) acre, one (1) parcel may be allowed to be smaller than the required minimum lot size. If all other parcels meet the required minimum lot size standard of the zone, one parcel may be allowed to be 6,250 square feet in size in the R-6 zone. Submitted plans would need to show compliance with the required lot size and dimensional standard with the land use application. Building Standards – The R-6 standards allow a maximum building coverage of 40 percent (40%) of the lot area. The maximum impervious coverage in the R-6 zone is 55 percent (55%). The maximum wall plate height is restricted to 24 feet (24’), and the buildings shall be not more than two (2) 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 vertical feet (4’) 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 horizontal feet (1.5’) from each façade for each one vertical foot (1’) above the maximum wall plate height. The maximum wall plate height for detached accessory structures is 12 feet (12’) and the total floor area must be less than that of the primary structure. Accessory structures are also included in building lot coverage calculations. Building elevations were not included with the submitted pre-application materials, therefore staff was unable to verify compliance with the Building Height requirements. New development would need to comply with the maximum building coverage, impervious surface requirements, and building height regulations of the zone at the time of building permit review. Existing development proposed for retention would also be required to comply with building and coverage limitations and would be reviewed for compliance at the time of land use application. Serduk Short Plat Page 3 of 7 September 25, 2024 PRE24-000256_PlanningComments_240908 Setbacks – Setbacks are the minimum required distance between the building footprint and the property line. The required setbacks for the R-6 zone are: Front yard: 25 feet (25’); Rear yard: 25 feet (25’); Side yards: combined 15 feet (15’) with not less than 5 feet (5’) on either side; and secondary front yards: 25 feet (25’). Within subdivisions, the minimum front yard and secondary front yard setback may be reduced to no less than twenty feet (20') provided the applicant can demonstrate to the Administrator’s satisfaction that the setback reduction is necessary to preserve and maintain a landmark tree within a tree protection tract, as each term is defined in RMC 4-11-200, Definitions T. An arborist report, pursuant to RMC 4-8- 120D.1, shall be prepared and provided to the City for review and concurrence, demonstrating that the setback reduction and project proposal serve to preserve the critical root zone of the tree within a tree protection tract. Compliance with required setbacks for new development would be verified at the time of building permit application. Existing development proposed for retention would be reviewed for compliance at the time of land use application. 3. Residential Design and Open Space Standards: Residential Design and Open Space Standards: Future single-family building permits would be subject to the RMC 4-2-115, Residential Design and Open Space Standards. Requirements related to garages, entries, modulation, windows/doors, scale, bulk, and character, roof forms, eaves, architectural detailing, and materials/color should be reviewed in their entity prior to submitting permit applications. 4. Landscaping: With the exception of critical areas, all portions of the development area not covered by structures, required parking, access, circulation or service areas, must be landscaped with native, drought-resistant vegetative cover. The minimum on-site landscape width required along street frontages is 10 feet and shall contain trees, shrubs, and landscaping. Street trees in the ROW planter will also be required. Landscaping may include hardscape such as decorative paving, rock outcroppings, fountains, plant containers, etc. Minimum planting strip widths between the curb and sidewalk are established according to the street development standards of RMC 4-6-060, Street Standards. Street trees and, at a minimum, groundcover is to be located in this area when present. Street trees shall be planted in the center of the planting strip between the curb and the sidewalk at the following intervals: provided, that, where right-of-way is constrained, irregular intervals and slight increases or decreases may be permitted or required. Additionally, trees shall be planted in locations that meet required spacing distances from facilities located in the right-of-way including, but not limited to, underground utilities, streetlights, utility poles, traffic signs, fire hydrants, and driveways; such spacing standards are identified in the City’s Approved Tree List. Generally, the following spacing is required: i. Small-sized maturing trees: thirty feet (30') on center; ii. Medium-sized maturing trees: forty feet (40') on center; and iii. Large-sized maturing trees: fifty feet (50') on center. A conceptual landscape plan shall be provided with the land use application as prepared by a licensed Landscape Architect, a certified nurseryman or other certified professional. Please be aware that frontage improvements will be required. Storm drainage facilities are required to comply with the minimum 15-foot perimeter landscaping strip on the outside of the fence unless otherwise determined through the site plan review or subdivision review process. Please refer to landscape regulations RMC 4-4-070 for further general and specific landscape requirements. Serduk Short Plat Page 4 of 7 September 25, 2024 PRE24-000256_PlanningComments_240908 5. Significant Tree Retention: A review of COR Maps appears to show that there are mature trees on the site. When significant trees (greater than 6-inch caliper or 8-caliper inches for alders and cottonwoods) are proposed to be removed, a tree inventory and a tree retention plan along with an arborist report, tree retention plan and tree retention worksheet shall be provided with the formal land use application as defined in RMC 4-8-120. The tree retention plan must show preservation of at least 30% of significant trees. Please refer to RMC 4-4-130, Tree Retention and Land Clearing Regulations for further general and specific tree retention and land clearing requirements. In addition to retaining a minimum of 30% of existing significant trees, each new lot would be required to provide a minimum tree density of 30 tree credits per net acre. Tree credits encourage retention of existing significant trees with larger trees being worth more tree credits. TREE SIZE TREE CREDITS New small species tree 0.25 New medium species tree 1 New large species tree 2 Preserved tree 6 – 9 caliper inches 4 Preserved tree 10 – 12 caliper inches 5 Preserved tree 12 – 15 caliper inches 6 Preserved tree 16 – 18 caliper inches 7 Preserved tree 19 – 21 caliper inches 8 Preserved tree 22 – 24 caliper inches 9 Preserved tree 25 – 28 caliper inches 10 Preserved tree 29 – 32 caliper inches 11 Preserved tree 33 – 36 caliper inches 12 Preserved tree 37 caliper inches and greater 13 Protected trees shall be retained in the order of priority listed in RMC 4-4-130H.2. Protection of trees or groves by placement within a dedicated tract (Tier 1) is the highest priority. 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 Serduk Short Plat Page 5 of 7 September 25, 2024 PRE24-000256_PlanningComments_240908 and their associated buffers; significant trees over sixty feet (60') in height or greater than eighteen inches (18") caliper; and trees that shelter interior trees or trees on abutting properties from strong winds, which could otherwise allow such sheltered trees to be blown down if removed. 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. The Administrator may authorize the planting of replacement trees on the site if it can be demonstrated to the Administrator's satisfaction that replacement requirements in RMC 4-4- 130H1e can be met. Tree retention standards shall be applied to the developable area, as defined in RMC 4-11- 040, Definitions D, of a property. A formal tree retention plan and tree retention worksheet prepared by an arborist or landscape architect would be reviewed at the time of the land use application. 6. Fences/Retaining 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 and grading plan with top of wall and bottom of wall elevations. 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. The maximum height of any fence or retaining wall is 72-inches subject to further height limitations in setbacks and clear vision areas noted in RMC 4-4-040D. 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.
