DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: September 14, 2023 TO: Pre-Application File No. 23-000277 FROM: Jill Ding, Senior Planner SUBJECT: 254 Union – 254 & 316 Union Ave NE (APN 5182100012, 5182100011, and 5182100014) 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 subject property is located on the east side of Union Ave NE, just south of NE 4th St at 254 and 316 Union Ave NE (APN 5282100012, 5182100011, and 5182100014). The project site totals 73,694 square feet (1.69 acres) in area and is zoned Commercial Arterial (CA). The applicant proposes to develop the property by constructing a 5-story, 84,460 square foot mixed use building with 100 dwelling units, 2,200 square feet of lobby, and 2,000 square feet of ground floor commercial retail space. The average residential unit size would be 650 square feet. The proposal would include a combination of 106 surface and under building parking spaces. Access to the site is proposed to be provide via one curb cut off Union Ave NE. According to City of Renton (COR) Maps, the site is mapped with a Type Ns stream, a wetland, and sensitive slopes. Current Use: Currently the site is occupied with two single family residences, proposed for removal. 1. Zoning /Land Use Designation, and Overlays: The property is located within the Commercial Mixed Use (CMU) land use designation, the Commercial Arterial (CA) zoning designation, and Urban Design District D. Commercial & Mixed Use designations are place areas with established commercial and office areas near principle arterials. Residential uses are allowed as part of mixed-use developments, and support new office and commercial development that is more intensive than what exists to create a vibrant district and increase employment opportunities. The intention of this designation is to transform strip commercial development into business districts through the intensification of uses and with cohesive site planning, landscaping, signage, circulation, parking, and the provision of public amenity features. The 254 Union Page 2 of 11 September 14, 2023 CA Zone provides for a wide variety of retail sales, services, and other commercial activities along high-volume traffic corridors. Residential uses may be integrated into the zone through mixed-use buildings. Retail sales, and attached dwelling – flats are permitted uses within the CA zone. Attached dwelling units are permitted uses in the CA zone provided the buildings are mixed use with ground-floor commercial. In addition, the vertically mixed-use building must have at two (2) residential stories above ground floor commercial along any street in the CA zone. Within the CA zone, any development wherein dwelling units are proposed shall provide a minimum of 40% of gross commercial floor area equivalent to a percentage of the building footprint of all buildings on site containing residential dwelling units. At a minimum, the development shall include ground floor commercial space along any street frontage in conformance with the following standards: a) a minimum average depth of thirty feet (30') and no less than twenty feet (20') at any given point; b) a minimum floor -to- ceiling height of eighteen feet (18'), and a minimum clear height of fifteen feet (15') unless a lesser clear height is approved by the Administrator; c) ADA compliant bathrooms (common facilities are acceptable); d) a central plumbing drain line; and e) a grease trap and a ventilation shaft for a commercial kitchen hood/exhaust. For vertically mixed-use buildings, the façade necessary for interior entrances, lobbies, and areas/facilities developed for the exclusive use of the building’s residents, or their guests (“lobby facade” for the purposes of this Section), is limited to thirty five percent (35%) of the overall facade along any street frontage or the primary façade. The Administrator may allow the lobby facade to exceed thirty five percent (35%) if the depth of the commercial space exceeds the minimum required by RMC 4-4-150E, provided the increased percentage of lobby facade is generally proportional to the increased depth of commercial space. Commercial uses in residential mixed-use developments are limited to retail sales, on-site services, eating and drinking establishments, taverns, daycares, preschools, indoor recreational facilities, pet daycares, craft distilleries/small wineries/micro-breweries with tasting rooms, general offices not located on the ground floor, and similar uses as determined by the Administrator. The ground floor consists of approximately 2,000 square feet of commercial space and proposed 20-foot floor height between floor 1 and floor 2. The balance of the ground floor consists of structured parking, a vehicle ramp within the garage to the second floor, elevators, and stairs. The proposal for 2,000 square feet of the 19,765 square foot ground floor building footprint would result in a ground floor commercial space coverage of 10%. The proposal does not appear to provide the minimum required 40% gross commercial floor area and would need to be revised to comply with this requirement. 2. Development Standards: The project would be subject to RMC 4-2-120A, “Development Standards for Commercial Zoning Designations” effective at the time of complete application (noted as “CA standards” herein). Density – The minimum net residential density in the CA zone is 20 dwelling units per net acre. The maximum net residential density is 60 dwelling units per net acre in the City Center Community Planning Area. The area of public and private streets and critical areas would be deducted from the gross site area to determine the “net” site area prior to calculating density. The gross density of the site is 1.69 acres. The applicant is proposing 100 new dwelling units or 59 dwelling units per gross acre (100 du / 1.69 ac = 59 du/ac). The applicant would be 254 Union Page 3 of 11 September 14, 2023 required to submit a Density Worksheet and 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 in the CA zone is 5,000 square feet. There are no minimum requirements for lot width or depth within the CA zone at this location. A lot combination would be required to consolidate the three existing lots into one lot. The gross project site area would total 73,694 square feet, which exceeds the minimum lot size requirement of 5,000 square feet. Setbacks – Setbacks are the distance between the building and the property line or any private access easement or tract. Setback requirements in the CA zone are as follows: Minimum Front Yard 15 ft. Maximum Front Yard 20 ft. Minimum Secondary Front Yard 15 ft. Maximum Secondary Front Yard 20 ft. Minimum Rear Yard None, except 15 ft. if lot abuts a lot zoned residential. Minimum Side Yard None, except 15 ft. if lot abuts or is adjacent to a lot zoned residential Clear Vision Area In no case shall a structure over 42 in. in height intrude into the 20 ft. clear vision area defined in RMC 4-11-030. The project site is abuts an R-10 zone along the south property line and is adjacent to an R- 10 zone along the west property line. The project would be subject to 15-foot front yard setback, and a 15-foot side yard setback from the abutting R-10 zone. It is the applicant’s responsibility to demonstrate compliance with building setbacks at the time of formal application. Gross Floor Area – There is no minimum requirement for gross floor area. Building Height – Maximum building height in the CA zone is 50 feet, except 70 feet for vertically mixed use buildings (commercial and residential). Heights may exceed the Zone’s maximum height with a Conditional Use Permit. In no case shall building height exceed the maximum allowed by the Airport Compatible Land Use Restrictions, for uses located within the Federal Aviation Administration Airport Zones designated under RMC 4-3-020. If appears that the proposed 5-story building would have a height less than 70 feet, which would comply with the maximum building height for vertically mixed use buildings. The final building height and coverage requirements would be verified at the time of formal application. Maximum Lot Coverage for Buildings – The CA zone allows a maximum building coverage of 65 percent, or 75 percent if parking is provided within a building or within an on-site parking garage. A portion of the parking is proposed would be structured parking. It is estimated that the building coverage is approximately 27 percent of the lot area (19,765 square feet / 73,694 square feet = 27%). It is the applicant’s responsibility to demonstrate compliance with building coverage requirements at the time of formal application.

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. 254 Union Page 6 of 11 September 14, 2023 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 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. 254 Union Page 7 of 11 September 14, 2023 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 credit 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 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 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).

Examples include sconces on building facades, awnings with down-lighting and decorative street lighting. 10. Critical Areas: The project site is mapped with a Type Ns stream, a wetland, and sensitive slopes. A wetland report and delineation and a stream study prepared by a certified biologist would be required at the time of formal land use application. A Type Ns stream would have a standard buffer of 50 feet with a 15-foot building setback. If any impacts are proposed to the wetland, stream, or their associated buffer, a mitigation plan would be required to be submitted with the land use application. A wetland report and stream study would be required to be submitted with the project application. In addition, secondary review may also be required, at the applicant’s expense. Due to the presence of geological hazards, a geotechnical report would be required at the time of formal land use application. The study shall specifically address if the proposal will not increase the threat of the geological hazard to adjacent or abutting properties beyond pre- development conditions; and the proposal will not adversely impact other critical areas; and the development can be safely accommodated on the site. It is the applicant’s responsibility to determine whether any other critical areas are present on the site prior to formal land use application. 11. Environmental Review: The proposal would be subject to Environmental (SEPA) Review as the proposal includes the construction of a new mixed use building that would be in excess of 4,000 square feet. 254 Union Page 10 of 11 September 14, 2023 12. Site Plan Approval: Per RMC 4-9-200, site plan review is required for any development in the CA zone. The purpose of the site plan review process is to analyze the detailed arrangement of project elements to mitigate negative impacts where necessary to ensure project compatibility with the physical characteristics of a site and with the surrounding area. Site plan review ensures quality development consistent with City goals and policies. Site plan review analyzes elements including, but not limited to, site layout, building orientation and design, pedestrian and vehicular environment, landscaping, natural features of the site, screening and buffering, parking and loading facilities, and illumination to ensure compatibility with potential future development. Decisional criteria for site plan approval are itemized in RMC 4-9-200.E.3. 13. Permit Requirements: The proposed project would require Hearing Examiner Site Plan Review and Environmental (SEPA) Review. All land use permits would be processed within an estimated time frame of 12 weeks. The 2023 application fees are as follows: Hearing Examiner Site Plan Review is $4,270 and SEPA Review (Environmental Checklist) is $1,800. A 5% technology fee would also be assessed at the time of land use application. 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. In addition to the required land use permits, separate construction and building permits would be required. 14. Public Information Sign: Public Information Signs are required for all Type II and Type 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. The applicant is solely responsible for the construction, installation, maintenance, removal, and any costs associated with the sign. 15.

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. 16. Public Outreach Sign: Preliminary plats, Planned urban development applications, and 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 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 254 Union Page 11 of 11 September 14, 2023 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. 17. Impact Fees: In addition to the applicable building and construction fees, impact fees would be required. Fees change periodically and the fees in effect at the time of building permit issuance would apply. For informational purposes, the 2022 impact fees are as follows: • A Fire impact fee $964.53 per new multi-family dwelling unit, and $1.25 per square foot for retail; • A transportation impact fee would be based on the land use.
