DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: March 16, 2023 TO: Pre-Application File No. 23-000057 FROM: Andrew Van Gordon, Associate Planner SUBJECT: Dreamliner - 26 Unit MultiFamily - Mixed Use 511 Airport Way (APN 7229300580) 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 project location is at 511 Airport Way (APN 7229300580). The site is split zoned between the Commercial Arterial (CA) zone and the Center Downtown (CD) zone. The CA portion is within Urban Design District D, and the CD zone is within the Urban Design District A. The proposal is for a four (4) story mixed use building with commercial space and structured parking on the ground floor, and 26 market rate units on floors two (2) through (4). Thirty -one (31) total parking stalls are proposed with nine (9) of the stalls being located off-site on the abutting property in a newly developed surface parking area. Access to the building is proposed via two (2) points: one (1) from the north accessing from Airport Way, and one (1) from the south accessing from the alley. Access to the off-site parking would be via the alley. As part of the project the applicant is requesting a deviation from the minimum required commercial space for a mixed- use building in the CA zone. Per COR Maps the site is within a High Seismic Hazard Area and Downtown Wellhead Protection Area Zone 1. Current Use: The site is 16,000 square feet (approximately 4,000 square feet within the CD zone and 10,000 square feet within the CA zone); it is currently vacant. It abuts Airport Way to the north and an alley to the south named, per COR Maps, S Tillicum St. 1. Zoning /Land Use Designation, and Overlays: The subject property is located within the CA and CD zone; both are within the Commercial & Mixed Use (CMU) comprehensive plan designation. The purpose of the CA zone is to evolve from “strip commercial” linear business districts to business areas characterized by enhanced site planning and pedestrian orientation, incorporating efficient parking lot design, coordinated access, amenities and Dreamliner - 26 Unit MultiFamily - Mixed Use Page 2 of 12 March 16, 2023 boulevard treatment with greater densities. The 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. The zone includes the designated Automall District. The purpose of the CD zone is to provide a mixed- use urban commercial center serving a regional market as well as high-density residential development. Uses include a wide variety of retail sales, services, multi-family residential dwellings, and recreation and entertainment uses. The proposed residential units would be within the attached dwellings – flats use. With the CA and the CD zone they are permitted, however residential use(s) are not allowed within one thousand feet (1,000') of the centerline of Renton Municipal Airport runway. Specific commercial tenants were not provided for the commercial spaces, however, within both the CA and the CD zone 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/micro-breweries with tasting rooms, general offices not located on the ground floor and similar uses as determined by the Administrator. Uses normal and incidental to the building including, but not limited to, interior entrance areas, elevators, waiting/lobby areas, mechanical rooms, mail areas, garbage/recycling/compost storage areas, vehicle parking areas, and areas/facilities for the exclusive use of the residents are not considered commercial uses. Residential uses in the CA zone must be integrated into a vertically mixed-use building with ground floor commercial situated closest to the street. In standalone residential buildings within the CD Zone outside of the Downtown Business District, residential amenity space and/or lobby space shall be provided on the ground floor along the street frontage, which shall be at least twenty feet (20') wide and at least fifty percent (50%) of the fa cade width for facades less than sixty feet (60') wide, or a minimum of thirty feet (30') wide for facades greater than sixty feet (60') wide. (Widths shall be measured along the building facade.) The ground floor shall have a floor-to-ceiling height of twelve feet (12'). Where located on the ground floor and within ten feet (10') of public sidewalk, the floors of attached dwellings shall be at least two feet (2') elevated above the grade of the sidewalk. 2. Development Standards: The project would be subject to RMC 4-2-120A, Development Standards for Commercial Zoning Designations (CN, CV, CA, & UC) and RMC 4-2-120B, Development Standards for Commercial Zoning Designations (CD, CO, & COR) effective at the time of complete application (noted as “CA standards” and “CD standards” herein). Density – The minimum net residential density for the CA zone is 20 dwelling units per net acre with a maximum of 60 dwelling unit per net acre in the City Center and Highlands Community Planning Areas. The minimum net residential density for the CD zone is 75 dwelling units per net acre with a maximum of 150 dwelling units per net acre. Density may be increased up to 250 dwelling units per net acre in the CD zone subject to conditional use permit approval. Net density is calculated by subtracting critical areas (very high landslide hazard areas, protected slopes, wetlands, Class 1 to 4 streams and lakes, or floodways), public rights-of-way and legally recorded private access easements from the gross area. 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 is 0.50 or greater shall be rounded up to the nearest whole number. Those Dreamliner - 26 Unit MultiFamily - Mixed Use Page 3 of 12 March 16, 2023 density calculations resulting in a fraction that is less than 0.50 shall be rounded down to the nearest whole number. 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. Based on the approximate gross land area of 0.09 acre in the CD zone, the proposal arrives at a gross density of approximately 133.33 du/ac (12 dwelling units / 0.09 gross acre = 133.33 du/ac). Based on the approximate gross land area of 0.27 acre in the CA zone, the proposal arrives at a gross density of approximately 51.85 du/ac (14 dwelling units / 0.27 acre = 51.85 du/ac). Dedication required for existing roads is not subtracted from the gross area. Building Standards – The maximum lot coverage for buildings within the CA zone is 65% of the total lot area or 75% if parking is provided within the building or within an on-site parking garage. There is no maximum lot coverage for buildings within the CD zone. The provided drawings show the building coverage as being at 75% on the CA portion of the property. All parking for the CA uses is required to be provided within the on-site parking garage for the project to receive the benefit of a 75% building co verage allowance. Within the CD zone portion the building coverage is 100%. Compliance with building standards would be reviewed at time of formal land use application. Setbacks – Setbacks are the minimum required distance between the building footprint and the property line. The required setbacks for the CA zone are: minimum front yard and secondary front yard setback: 15 feet (15’); maximum front yard and secondary front yard setback: 20 feet (20’); minimum side yard setback: none, except 15 feet (15’) if the lot abuts or is adjacent to a lot zoned residential; minimum rear yard setback: none, except 15 feet (15’) if the lot abuts a lot zoned residential. The required setbacks for the CD zone are: minimum front yard and secondary front yard: none; maximum front yard and secondary front yard 15 feet (15’) for buildings or portions of buildings 25 feet (25’) in height or less and none for portions of the building over 25 feet (25’) in height; minimum side yard: none, unless the ground floor façade provides living room windows of attached dwellings – then 10 feet (10’) – unless adjacent to an alley, then none; minimum rear yard: none, unless the ground floor façade provides windows for living rooms of attached dwellings – then 10 feet (10’) – unless adjacent to an alley, then none. Additionally, within the CD zone upper story’s do not have a setback unless adjacent to and facing a residentially zoned lot or if the façade contains living room windows – then 10 feet (10’) for the second story and 15 feet (15’) for all upper stories. Compliance with setback standards would be reviewed at the time of formal land use application. Building Height and Impervious Surface Coverage – Neither zone has a maximum impervious surface coverage limit. The maximum height for the CA zone is 50 feet (50’) except 70 feet (70’) for vertically mixed-use buildings (commercial and residential). Heights may exceed the Zone’s maximum height with a Conditional Use Permit. The maximum height for the CD zone is 150 feet (150’). In no case shall building height exceed the maximum allowed by the Airport Related Height and Use Restrictions for uses located within the Airport Influence Area and Dreamliner - 26 Unit MultiFamily - Mixed Use Page 4 of 12 March 16, 2023 Safety Compatibility Zones designated under RMC 4-3-20, Airport Related Height and Use Restrictions. The proposal appears to be within Airport Safety Zone 5 and Zone 6. Airport restrictions place the maximum height between 152 feet (152’) and 172 feet (172’) based on the location on the property. Of note, the land use application must include a certificate from an engineer or land surveyor, that clearly states that the proposed use will not penetrate the Federal Aviation Administration Regulation Part 77 Objects Affecting Navigable Airspace, or the maximum elevation of proposed buildings or structures based on the established airport elevation reference datum will not penetrate the Federal Aviation Administration Regulation Part 77 Objects Affecting Navigable Airspace are required. Elevations shall be determined by an engineer or land surveyor for the second option. The proposal shall meet all applicable requirements in RMC 4-3-020. The building height and coverage requirements would be verified at the time of formal land use application. 3. Refuse and Recycling Areas: All new developments for multi-family, commercial, industrial and other nonresidential uses shall provide onsite refuse and recyclables deposit areas and collection points for collection of refuse and recyclables. For multi-family, a minimum of one and one-half (1 – ½) square feet per dwelling unit shall be provided for recyclable deposit areas. A minimum of three (3) square feet per dwelling unit shall be provided for refuse deposit areas. In retail developments, a minimum of five (5) square feet per every 1,000 square feet of building gross area shall be provided for recyclables deposit areas and a minimum of 10 square feet per 1,000 square feet of building gross floor area shall be provide for refuse deposit areas.

Urban Design Regulations: Compliance with Urban Design Regulations, District ‘A’ on the CD portion and District ‘D’ on the CA portion, is required. The land use application shall provide a written narrative to identify how the project meets each applicable urban design regulation. Please refer the standards in their entirety at RMC 4-3-100, Urban Design Regulations. The following bullets are the applicable design requirements. Comments are general and do not cover in detail every specific regulation within the applicable requirements. • RMC 4-3-100E1: Site Design and Building Location o Building Location and Orientation The availability of natural light (both direct and reflected) and direct sun exposure to nearby buildings and open space is not discussed. o Building Entries Dreamliner - 26 Unit MultiFamily - Mixed Use Page 8 of 12 March 16, 2023 The primary entrances are not visibly prominent as architectural features separating them from each other and the rest of the façade are not present. o Transition to Surrounding Development A discussion identifying how the proposal is meeting an appropriate transition to surrounding uses was not provided. o Service Element Location and Design Service elements, which include refuse and recycling areas shall have self- closing doors. • RMC 4-3-100E2: Parking and Vehicular Access o Surface Parking o Vehicular Access Access to the parking garage shall be from alleys. • RMC 4-3-100E3: Pedestrian Environment o Pedestrian Circulation The off-site parking requires a pedestrian connection to the sidewalk along Airport Way. Pathways within surface parking areas shall be provided and differentiated by material and/or texture. No pedestrian connection is made to the commercial space in the CA zone. Permeable pavement for pedestrian circulation features shall be used when feasible, consistent with the Surface Water Design Manual. o Pedestrian Amenities Only applicable to Urban Design District D (CA zone portion). Architectural elements that incorporate plants, especially at entrances shall be included. Amenities such as outdoor seating, benches, fountains and public art shall be provided. Identification about how pedestrian overhead weather protection is being provided is needed. • RMC 4-3-100E4: Recreation Area and Common Open Space o Recreation Areas and Common Open Space One thousand three hundred (1,300) square feet of open space and/or recreation areas is required. It appears that approximately 1,232 square feet is proposed (clubroom, clubroom terrace, exercise/yoga room). The conference rooms on floor 3 and floor 4 are not considered common open space/recreation areas. Amenities are not listed for the clubroom. The clubroom terrace will need to include amenities such as grills, seating areas and vegetation. The exercise/yoga room will need to include exercise equipment. • RMC 4-3-100E5: Building Architectural Design o Building Character and Massing Dreamliner - 26 Unit MultiFamily - Mixed Use Page 9 of 12 March 16, 2023 The building is not meeting façade modulation requirements on the north façade or the east façade. o Ground Level Details Untreated blank walls visible from public streets, sidewalks or interior pedestrian pathways are prohibited. All four facades are visible from public streets and/or sidewalks. Untreated blank walls are found on the south façade, east façade and west façade. If blank walls are unavoidable, they shall be treated through means such as vegetation, architectural detailing, artwork etc. Within District A at least 75% of the façade visible to the public shall be comprised of transparent doors and/or windows between four feet and eight feet (4’ – 8’) about ground; within District D at least 50% is required. Calculations were not provided. o Building Roof Lines It is unclear how the building roof profile is meeting requirements. Buildings containing predominantly residential uses shall have pitched roofs with a minimum slope of one to four (1:4) and shall have dormers or interesting roof forms that break up the massiveness of an uninterrupted sloping roof. It appears that the roof is flat. o Building Materials Material and color variation is required. Planning will not support the project using both white and grey as colors as they do not provide enough variation. At least one (1) additional material such as wood, shall be used as the current material list does not provide enough variation. Concrete shall be enhanced with textures, reveals and/or coloring with a concrete coating or admixture that is integrally incorporated into the design of the structure. • RMC 4-3-100E7; Lighting o Lighting A lighting plan would need to be submitted with the formal land use application.

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. The project only includes approximately 23 percent (23%) of the gross ground floor area within the CA zone for commercial space. Provided materials indicate that the applicant will be requesting a modification to reduce the commercial space because loose soils prevent a below ground level parking level and height restrictions due to proximity to the airport prevents additional vertical development. Conformance with standards would be reviewed at the time of formal land use application. See RMC 4-4-150, Residential Mixed-Use Development Standards for full requirements. 10. Attached Dwelling Units – Minimum Standards: Buildings containing four (4) or more attached dwelling units shall provide at least one (1) unit with two (2) or more bedrooms for every four (4) units in the structure. One (1) bedroom units shall have a minimum habitable area of 600 square feet. Two (2) bedroom units shall have a minimum habitable area of 800 square feet. Units with no more than two (2) bedrooms shall include at least one (1) complete bathroom with a sink, a toilet and both a shower and bathtub. Minimum kitchen and storage space standards also apply. At least 55 cubic feet of additional storage space, located anywhere within the building, shall be provided for each unit. There are three (3) two-bedroom units that do not meet the minimum 800 square foot habitable space. It is unclear how the additional storage space requirement is being met; 1,430 cubic feet of additional storage space is required. Compliance with applicable requirement would be reviewed at the time of formal land use application. See RMC 4-4- 155, Attached Dwelling Units – Minimum Standards for full requirements. 11. Critical Areas: According to COR Maps, Wellhead Protection Area Zone 1 and Seismic Hazard Area: High are mapped on the property. The overall purpose of the wellhead protection regulations is to protect aquifers used as potable water supply sources by the City from contamination by hazardous materials. Some uses are restricted that store, handle, treat, use or produce substances that pose a hazard to groundwater quality. If fill is used then a fill source statement is needed. Development within high seismic hazard areas require a geotechnical study completed by a licensed professional. Due to the presence of geological hazards, a geotechnical study will be required at the time of 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. 12. Environmental Review: Environmental review is required for projects with 10 or more dwelling units. 13. Site Plan Approval: Per RMC 4-9-200, site plan review is required for any development in the CA and CD 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. Dreamliner - 26 Unit MultiFamily - Mixed Use Page 11 of 12 March 16, 2023 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. All commercial or industrial projects adjacent to or abutting residentially zoned property, unless the Administrator determines that the presence of critical areas or other limiting factors on the residential property make development unlikely or unfeasible. Decisional criteria for site plan approval are itemized in RMC 4-9-200.E.3. The project is adjacent to residentially zoned property to the south and as such a public hearing is required. 14. Permit Requirements: The proposal would require Hearing Examiner Site Plan Review and an Environmental Review (SEPA). Based on the 2023 feet in effect at the time of these comments, to total is $6,373.50 ($4,270.00 Hearing Examiner Site Plan + $1,800.00 Environmental Review (SEPA) + $303.50 Technology Fee (5%) = $6,373.50). Each modification request is $290.00. A 5% technology fee added to the total cost of the reviews would also be assessed at the time of land use application. All fees are subject to change.
