M E M O R A N D U M DATE: September 14, 2023 TO: Andrew Van Gordon, Senior Planner FROM: Corey Thomas, Lead Plans Review Inspector SUBJECT: Bach and Chan Short Plat 1. The fire flow requirement for a single-family home is 1,000 gpm minimum for dwellings up to 3,600 square feet (including garage and basements). If the dwelling exceeds 3,600 square feet, a minimum of 1,500 gpm fire flow would be required. A minimum of on e fire hydrant is required within 300-feet of the proposed buildings and two hydrants if the fire flow goes up to 1,500 gpm. Existing hydrants can be used to satisfy some requirements; however, it appears one new fire hydrant will be required to meet the minimum requirements. 2. The fire impact fees are currently applicable at the rate of $829.77 per single family unit. This fee is paid at building permit issuance. Credit will be granted for the removal of the one existing house. 3. Fire department apparatus access roadways are required to be a minimum of 20-feet wide fully paved, with 25-feet inside and 45-feet outside turning radius. Fire access roadways shall be constructed to support a 30-ton vehicle with 75-psi point loading. Access is required within 150 feet of all points on the buildings. The maximum grade is 15 percent. An approved hammerhead turnaround is required. See the attached standard plan for minimum dimensions. It appears the proposed turnaround is too small to meet the minimum dimensions.

DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: October 12, 2023 TO: Pre-Application File No. 23-000297 FROM: Andrew Van Gordon, Associate Planner SUBJECT: Bach & Chan Development – 3309 NE 7th St (Parcel number 8011100090) 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 proposes to subdivide 3309 NE 7th St (APN 8011100090) into four (4) residential lots for the benefit of detached dwellings. The property has street frontage along NE 7th St to the north. The lot is located within the Residential – 8 (R-8) zone. Access is proposed via a shared driveway from NE 7th St. Per COR Maps, the property is approximately 28,749 square feet (0.6599 acre). Current Use: The project area is currently developed with a detached dwelling and detached accessory structure. Both structures are proposed to be removed. Per COR Maps sensitive slopes (>25% & <=40%) are present on the site. Zoning/Land Use: The subject property is located within the Residential-8 (R-8) zoning classification. The Residential Medium Density Land Use designation is intended to implement the R-8 zone. The R-8 zone is established for single family dwellings. Development in the R-8 Zone 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. It is intended to accommodate uses that are compatible with and support a high- quality residential environment and add to a sense of community. Detached dwellings are permitted within the R-8 zone. 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 Bach & Chan Development Page 2 of 8 October 12, 2023 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-8 zone has a minimum density of four (4) dwelling units per acre with a maximum of eight (8) dwelling units per acre. Based on the approximate gross land area of 0.6599 acre, the four (4) lot proposal arrives at a gross density of approximately 6.06 du/ac (4 lots / 0.6599 gross acre = 6.06 du/ac). The gross density would result in 6.06 du/ac; however, the applicant would be required to demonstrate compliance with the net density requirements of the zone at the time of formal application. A density worksheet be required with the land use application. Development Standards: The project would be subject to RMC 4-2-110A, Development Standards for Residential Zoning Designations effective at the time of complete application (noted as “R-8 standards” herein). Minimum Lot Size, Width and Depth – The minimum lot size permitted in the R-8 zone is 5,000 square feet for parcels being subdivided. 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 4,500 square feet in size in the R-8 zone. Minimum lot width is 50 feet (50’) for interior lots and 60 feet (60’) for corner lots; minimum lot depth is 80 feet (80’). Compliance with minimum lot size, width and depth standards would be verified at the time of land use application. Building Standards – The R-8 standards allow a maximum building coverage of 50 percent (50%) of the lot area. The maximum impervious coverage in the R-8 zone is 65 percent (65%). 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. 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. 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 (20’) except when all vehicle access is taken from an alley, then 15 feet (15’); Secondary front yard (applies to corner lots): 15 feet (15’); Rear yard: 25 feet (25’); Side yard: five feet (5’) An arborist report, pursuant Bach & Chan Development Page 3 of 8 October 12, 2023 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. Of note, a front yard or secondary front yard (depending on lot orientation) setback from the shared driveway tract would be required. 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. Compliance with lot configuration requirements would be verified at the time of land use application. Compliance with building design requirements would be verified at the time of building permit review. Access/Parking: Access to the lots are proposed via NE 7th St. Each lot is required to accommodate off street parking for a minimum of two (2) vehicles. The maximum width of single loaded garage driveways shall not exceed nine feet (9’) and double loaded garage driveways shall not exceed 16 feet. Maximum driveway slopes shall not exceed 15 percent; provided, that 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. Driveways shall not be closer than five feet (5’) to any property line except as allowed per RMC 4-4-080I.9, Joint Use Driveways. Shared driveways may be allowed for access to no more than four (4) residentially zoned lots, and no more than four (4) residential units, the types of which are listed in RMC 4-2-060C, provided: a. At least one lot 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 10 or more lots; c. A public street is not anticipated by the City of Renton to be necessary for existi ng 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 300 feet (300’) in length; and f. The shared driveway poses no safety risk and provides sufficient access for emergency vehicles and personnel. The Administrator may permit lots that only front a shared driveway to be designated as a corner lot. If permitted by the Administrator, lot width, lot depth and yard setbacks shall be measured consistent with the corner lot designation (see illustration below). Bach & Chan Development Page 4 of 8 October 12, 2023 Shared driveways shall be within a tract; the width of the tract and paved surface shall be a minimum of 16 feet (16'); the Fire Department may require the tract and paved surface to be up to 20 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. Compliance with access and driveway requirements would be verified at the time of land use application. 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 Bach & Chan Development Page 5 of 8 October 12, 2023 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 are 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 applica tion 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. Significant Tree Retention: 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 Bach & Chan Development Page 6 of 8 October 12, 2023 TREE SIZE TREE CREDITS 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 within a subdivision 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 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- 130H.1.e 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. 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 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.
