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, 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 a residential townhome development at 430 Maple Avenue SW (parcel no. 1823059165). The project site totals approximately 58,065 sq. ft. (1.33 acres) and is located within the Residential Multi-Family (RMF) zoning classification, Urban Design District B, and the Residential High Density (RHD) land use designation. The proposal would include three separate townhome residential structures with 5-9 residential units per building resulting in a total of 19 dwelling units on the project site. Access to the site is proposed via new dead end limited residential access street off of Maple Avenue SW which would transition to alley access, serving the individual townhome units. According to COR Maps, the site is mapped with Protected Slopes, Sensitive Slopes, a seismic hazard area, and a wellhead protection area, zone 2. Current Use: The previously existing structures located onsite have been demolished, the project site is currently vacant. Zoning Requirements: The property is located within the Residential High Density (RHD) land use designation, the Residential Multi-Family (RM-F) zoning designation, and Urban Design District B. Attached dwellings - townhouses are a permitted use within the RM-F zone, provided specified use(s) shall be subject to the standards of RMC 4-2-115, Residential Design and Open Space Standards, applicable to the R-10 and R-14 Zones, in lieu of the overlay design district B standards of RMC 4-3-100.

Density Requirements: The density range allowed in the RM-F zone is a minimum of 10.0 to a maximum of 20.0 dwelling units per net acre (du/ac). The area of public and private streets and 430 Maple Avenue Preapplication Meeting September 7, 2023 2 critical areas would be deducted from the gross site area to determine the “net” site area prior to calculating density. After the deduction of an estimated 4,150 sq. ft. of right-of-way dedication and 6,600 sq. ft. of protected slopes, the project site would have a net area of 47,315 sq. ft. or 1.086 net acres. The proposal for 19 units on the 1.086 net acre site would result in a net density of approximately 17.50 du/ac, which is within the density range permitted in the RM-F zone. The applicant would be required to submit a density worksheet at the time of formal land use application demonstrating compliance with the net density requirements. Unit Lot Subdivision Standards: Parent sites developed or proposed to be developed with attached townhouse dwellings may be subdivided into unit lots and the remainder of the parent site shall be platted as one or more tracts. Any private open space or private amenities for a dwelling unit shall be provided on the same unit lot as the dwelling unit. The density of the parent site shall not exceed the maximum net density of the zone. Only one dwelling unit shall be located on a unit lot. Individual unit lots created for townhouse developments are exempt from the following standards of RMC 4-2-110A, Development Standards for Residential Zoning Designations (Primary and Attached Accessory Structures): maximum net density, minimum lot size, minimum lot width, minimum lot depth, yard setbacks, maximum building coverage, and maximum impervious surface area. The parent site would need to comply with all development standards as though it were a standalone lot. Please see RMC 4-7-090 for additional requirements and regulations for unit lot subdivisions.

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 4 430 Maple Avenue Preapplication Meeting September 7, 2023 5 TREE SIZE TREE CREDITS 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 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- 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. Fences/Retaining Walls: If the applicant intends to install any fences as part of this project, the location must be designated on the landscape plan. A wall taller than four feet requires a building permit. Fences up to six-feet in height are permitted in the rear yard and side yard; fences up to four feet are permitted in the front yard. Any part of a yard that is within a clear vision area has a 430 Maple Avenue Preapplication Meeting September 7, 2023 6 limited fence height of 42 inches. 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. New or existing fencing would need to comply with the fence requirements of the code (RMC 4-4-040). Retaining walls shall be composed of brick, rock, textured or patterned concrete, or other masonry product that complements the proposed building and site development. There shall be a minimum three-foot (3') landscaped setback at the base of retaining walls abutting public rights- of-way. Please refer to retaining wall standards (RMC 4-4-040) for additional information about fences and retaining walls. Parking: Townhouse development requires a minimum and maximum of 2 onsite parking stalls per dwelling unit. Parking spaces within the garages shall be a minimum of 9’x20’. Parking stalls within garages may count toward minimum requirements. One-half (0.5) bicycle parking space is required per each dwelling unit. Spaces shall meet the requirements of RMC 4-4-080 F11c, Bicycle Parking Standards. The number of parking spaces required for attached dwellings pursuant to RMC 4-4-080F10d, Parking Spaces Required Based on Land Use, may be averaged and dispersed among unit lots or within the parent site; however, at least one parking space shall be provided within each unit lot. Compliance with this requirement would be verified at the time of formal land use application. Access/Driveways: Driveways shall not be closer than 5 feet to any property line and not exceed 40 percent of the street frontage. The width of any driveway shall not exceed 30 feet. The maximum driveway slopes cannot exceed 15%. If the grade exceeds 15%, a variance is required. Driveways exceeding 8% shall provide slotted drains at the lower end with positive drainage discharge to restrict runoff from entering the residences or crossing any public sidewalks. The proposed access is a 52-foot wide dead end limited residential access street, with 16-foot wide alleys and a motor court. The City does not have a standard for a motor court, access for the units shall be provided via a public street or alley. Critical Areas: According to COR Maps, the site is mapped with Protect Slopes, Sensitive Slopes, a seismic hazard area, and a wellhead protection area, zone 2. Development is not permitted on protect slopes, the proposed storm drainage facility within the protected slope area would need to be relocated outside of the protected slopes. A Geotechnical Report would be required at the time of formal land use application evaluating the suitability of the proposed development. The required study shall demonstrate the following review criteria can be met: (a) The proposal will not increase the threat of the geological hazard to adjacent or abutting properties beyond pre- development conditions; and (b) The proposal will not adversely impact other critical areas; and (c) The development can be safely accommodated on the site. The City may require secondary review of geotechnical studies and all fees associated with that review are the responsibility of the applicant. All protected slope areas shall be placed within a Native Growth Protection Area (NGPA). The applicant shall create a tract via the subdivision and record a permanent and irrevocable covenant running with the land or deed restriction on the property title of any critical area management tract or tracts created as a condition of a permit. Such covenant or deed restriction(s) shall prohibit development, alteration, or disturbance within the tract except for purposes of habitat enhancement as part of an enhancement project which has received prior written approval from the City, and from any other agency with jurisdiction over such activity. A covenant running with 430 Maple Avenue Preapplication Meeting September 7, 2023 7 the land shall be placed on the tract restricting its separate sale. Each abutting lot owner or the homeowners’ association shall have an undivided interest in the tract. It is the applicant’s responsibility to determine whether any other critical areas are present on the site prior to formal land use application. Environmental Review: The construction of nine (9) dwelling units or more on a project site requires Environmental (SEPA) Review in accordance with WAC 197-11-800. Subdivision: Unit lot subdivisions of greater than nine (9) unit lots shall be processed as a preliminary plat and are subject to all provisions of RMC 4-7-080, Detailed Procedures for Subdivisions, unless otherwise specified by this Section. Site Plan Review: The project would be subject to Hearing Examiner Site Plan Review. The purpose of the Site Plan process is the detailed arrangement of project elements so as to be compatible with the physical characteristics of a site and with the surrounding area. An additional purpose of the Site Plan is to ensure quality development consistent with City goals and policies. General review criteria includes the following: ▪ Compliance and Consistency. Conformance with plans, policies, regulations and approvals, including: - Off-Site Impacts. Mitigation of impacts to surrounding properties and uses. - On-Site Impacts. Mitigation of impacts to the site. - Appropriate Location. Not to result in overconcentration of a particular use. - Access and Circulation. Safe and efficient access and circulation for all users. - Open Space. Incorporation of public and private open spaces to serve as distinctive project focal points and to provide adequate areas for passive and active recreation by the occupants/users of the site. - Views and Public Access. Provision of view corridors to shorelines and Mt. Rainier, incorporates public access to shorelines, and arranges project elements to protect existing natural systems where applicable. - Services and Infrastructure. Availability of public services and facilities to accommodate the proposed use. - Phasing. Inclusion of a detailed sequencing plan with development phases and estimated time frames, if applicable. Permit Requirements: The proposal would require Hearing Examiner Site Plan Review, Preliminary Plat approval, and Environmental (SEPA) Review. The applications would be reviewed concurrently within an estimated time frame of 12 weeks. The 202 3 application fees would be $12,170 for the Preliminary Plat Review, $4,270 for the Site Plan Review, and $1,800 for the SEPA Checklist Review. Each modification request is $290. All fees are subject to 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 Permit Center website. The City now requires electronic plan submittal for all applications. 430 Maple Avenue Preapplication Meeting September 7, 2023 8 In addition to the required land use permits, separate construction and building permits would be required. For unit lot subdivisions, construction may commence upon approval of a site plan and issuance of a building permit prior to final subdivision approval and recording if all applicable permits and approvals have been obtained by the applicant. However, no dwelling unit or unit lot may be sold, transferred, occupied or conveyed prior to final subdivision approval and recording. Public Information Sign: Public Information Signs are required for all Type II and III Land Use Permits, as classified by RMC 4-8-080. Public Information Signs are intended to inform the public of potential land development, specific permits/actions being considered by the City, and to facilitate timely and effective public participation in the review process. The applicant must follow the specifications provided in the public information sign handout (see land use forms on City website). The applicant is solely responsible for the construction, installation, maintenance, removal, and any costs associated with the sign. Public Meeting: Please note a neighborhood meeting, according to RMC 4-8-090, is required for: a. Preliminary plat applications; b. Planned urban development applications; and c. Projects estimated by the City to have a monetary value equal to or greater than ten million dollars ($10,000,000), unless waived by the Administrator. The intent of this meeting is to facilitate an informal discussion between the project developer and the neighbors regarding the project. The neighborhood meeting occurs after a pre- application meeting and before submittal of applicable permit applications. The public meeting shall be held within Renton city limits, at a location no further than two (2) miles from the project site. Public Outreach Sign Preliminary Plat applications require the applicant to install a public outreach sign. Public outreach signs are intended to supplement information provided by public information signs by allowing an applicant to develop a personalized promotional message for the proposed development. The sign is also intended to provide the public with a better sense of proposed development by displaying a colored rendering of the project and other required or discretionary information that lends greater understanding of the project. 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. For information purposes, the 2023 impact fees are as follows but please note these fees change yearly: • A Transportation Impact Fee based on $8,031.94 per each new PM peak hour trip. • A Parks Impact Fee based on $2,222.84 per each new multi-family dwelling unit: 5 or more units. • A Fire Impact fee of $964.53 per each new single-family/townhome dwelling unit. • Renton School District Impact Fee is $3,697.00 per each new multi-family dwelling unit, plus a 5% processing fee.
