DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: July 28, 2022 TO: Pre-Application File No. 22-000239 FROM: Jill Ding, Senior Planner SUBJECT: Poppy Court Short Plat 805 Hoquiam Ave NE (parcel no. 1023059003) 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, 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 an existing parcel into three lots. The subject property is located at 805 Hoquiam Ave NE (parcel no. 1023059003), at the northeast corner of Hoquiam Ave NE and NE 8th St. The project site totals 18,603 square feet (0.43 acres) in area and is currently developed with a single-family home and associated detached accessory structures, which are 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 are 7,289 sq. ft. for Lot 1, 5,776 sq. ft. for Lot 2 and 7,280 sq. ft. for Lot 3. Access to Lot 1 is proposed off Hoquiam Ave NE and access to Lots 2 and 3 is proposed via residential driveways off of NE 8th St. There are no critical areas mapped on the project site. Current Use: The project site is currently developed with a single-family home 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 gross area of 18,603 square feet, a 3-lot proposal arrives at a gross density of 6.98 du/ac (3 lots / 0.43 acres = 6.98 Poppy Court Short Plat Page 2 of 5 July 28, 2022 du/ac), which is within the permitted density range; however, 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 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) 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. Minimum lot width is 50 feet for interior lots and 60 feet for corner lots; minimum lot depth is 80 feet. Please note that for short plats of parcels smaller than one acre, one 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. In the R-8 zone, one parcel may be allowed to be four thousand five hundred (4,500) square feet. As proposed, all lots appear to meet the requirements for the R-8 zone. It is the applicant’s responsibility to demonstrate compliance with the minimum lot size, width and depth criteria of the zone at the time of formal application. 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. 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 single-family residences would be required to be demonstrated 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; 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 or private street 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 would be verified at the time of building permit review. Access/Driveways/Parking: Access to Lot 1 is proposed off Hoquiam Ave NE and access to Lots 2 and 3 is proposed via residential driveways off of NE 8th St (an existing private street). The City does not have standards for private streets. 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; Poppy Court Short Plat Page 3 of 5 July 28, 2022 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. The proposal to access Lots 2 and 3 off of NE 8th St would result in a total of five (5) lots accessing off of the private street, which would exceed the maximum of four (4) lots permitted. The proposal would need to be revised to access all proposed lots off of Hoquiam Ave NE. 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. Compliance with the shared driveway and access standards would be verified at the time of formal land use application. Compliance with driveway and parking 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: 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. Poppy Court Short Plat Page 4 of 5 July 28, 2022 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. The City Council is currently considering changes to the current Tree Retention Regulations, it is likely that the proposed short plat would be subject to the new Tree Retention Ordinance. 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: Except when located in sensitive areas (such as wetland or protected slopes) or lands covered by water, short plats of 9 or fewer residential lots are categorically exempt from Environmental (SEPA) Review. Permit Requirements: The proposal would require administrative short plat approval. The application would be reviewed within an estimated time frame of six to eight weeks. The 2022 administrative short plat application fee is $5,680.50 ($5,410.00 each plus a 5% Technology Surcharge Fee). Each modification request is $273.00 ($260.00 each plus a 5% Technology Surcharge Fee). All fees are subject to change. Detailed information regarding the land use application submittal can be found on the City’s new website by clicking “Land Use Applications” on the Community & Economic Development page, then “All Forms (A to Z).” The City now requires electronic plan submittal for all applications. Once Preliminary Short Plat approval is obtained, the applicant must complete the required improvements and dedications, as well as satisfy any conditions of the preliminary approval before submitting for Final Short Plat review. Once final approval is received, the plat may be recorded. The newly created lots may only be sold after the plat has been recorded. In addition to the required land use permits, separate construction and building permits would be required. Poppy Court Short Plat Page 5 of 5 July 28, 2022 Public Notice: A minimum of one Public Information Sign is required for a Short Plat application. The applicant is responsible for the procurement, installation and maintenance of the sign. Detailed information regarding the land use application submittal requirements is provided on the City of Renton website (www.rentonwa.gov). Fees: In addition to the applicable building and construction fees, impact fees would be required. Such fees would apply to all projects and would be calculated at the time of building permit issuance and payable prior to building permit issuance. The 2022 impact fees are as follows: • A Transportation Impact Fee based on $10,861.69 per each new detached dwelling unit. • A Parks Impact Fee based on $2,914.99 per each new detached dwelling unit. • A Fire Impact fee of $829.77 per each new detached dwelling unit. • Renton School District Impact Fee is $7,681.00 per each new detached dwelling unit (plus an additional 5% service fee).
