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 www.rentonwa.gov. Project Proposal: The subject property (APN 032305-9093) is vacant parcel located on the south side of NE Sunset Blvd near the intersection of Anacortes Ave NE. The project site totals 0.81 acres in area and is located within the Commercial Mixed Use (CMU) land use designation, Commercial Arterial (CA) zoning classification, and Urban Design District ‘D’. The applicant proposes to construct 16 attached dwelling units and 1,929 square feet of commercial space. The project includes 16 garage parking spaces and 13 surface parking spaces. Access is proposed via two driveways along NE Sunset Blvd. Stream buffer encroachments are proposed along the southern portion of the property. The City’s mapping system indicates an Ns rated stream (Honey Creek) is located on the southeast corner of the property. Current Use: The subject property is currently vacant. Zoning: The CA zone allows attached dwelling units - flats with the following condition identified in RMC 4-2-080 footnote #6: Standalone residential buildings would not be permitted here as the site does not abut a residential zone. Therefore dwelling units shall be integrated into a vertically mixed use building with ground floor commercial and are subject to the Residential Mixed Use Development Standards (RMC 4-4-150). 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. Sunset Highlands Mixed Use Preapplication Meeting August 22, 2019 PRE19-000173 Uses normal and incidental to a 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 Mixed Use Development Standards: For vertically mixed use buildings, the facade necessary for interior entrances, lobbies, and areas/facilities developed for the exclusive use of the building’s residents, or their guests, is limited to twenty five percent (25%) of the overall facade along any street frontage or the primary facade. The commercial square footage shall be equivalent to fifty percent (50%) of the gross ground floor area of the building. The ground floor commercial is listed at 1,929 square feet and does not appear to meet the 50-percent threshold. An approved modification would be needed for this proposal. The development shall include ground floor commercial space along the street frontage per the following standards: A minimum average depth of thirty feet (30') and no less than twenty feet (20') at any given point; 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; ADA compliant bathrooms (common facilities are acceptable); A central plumbing drain line; and A grease trap and a ventilation shaft for a commercial kitchen hood/exhaust. Commercial Arterial (CA) Development Standards: The project would be subject to RMC 4-2- 120A, “Development Standards for Commercial Zoning Designations” and District ‘D’ overlay “RMC 4-3-100 “Urban Design Regulations” effective at the time of complete application (noted as “CA standards” herein). Density – The minimum density permitted in the CA zoning designation is 20 units/net acre and the maximum density is 60 units/net acre for buildings with mixed commercial and residential use in the same building and located in the Highlands Community Planning Area. Net density is calculated after the deduction of areas required for public right-of-way dedication, private access easements, and critical areas from the gross site area. Net density of the project could not be determined at the time of this memo. Gross density for the proposal indicates approximately 20 dwelling units per acre. A density worksheet verifying net density with any public street or critical area deductions will be required with the land use application. Minimum Lot Size, Width and Depth – There are no minimum requirements for lot size, lot width or depth within the CA zone at this location. Lot Coverage – 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. Building coverage would be limited to 65 percent as some surface parking is proposed. The proposal appears to meet this limitation. Setbacks – Setbacks are the minimum required distance between the building footprint and the property line and any private access easement or tract. The project would have a minimum 15- foot setback and maximum 20-foot setback from the NE Sunset Blvd ROW. No side or rear yard setbacks would apply to this site. Please refer to the critical areas section for stream buffer and Sunset Highlands Mixed Use Preapplication Meeting August 22, 2019 PRE19-000173 setback requirements. The building appears to be setback 15-feet from the front property line (NE Sunset Blvd). Height – Maximum building height is 50 ft., except 70 ft. for mixed use (commercial and residential) in the same building. Heights may exceed the Zone’s maximum height with a Conditional Use Permit, however 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. The project narrative indicates the building would be 55-feet in height and therefore meet the permitted height limits. Screening – Screening must be provided for all surface-mounted and roof top utility and mechanical equipment. The site plan application will need to include elevations and details for the proposed methods of screening. Refuse and Recycling Areas – Refuse and recycling areas need to meet the requirements of RMC 4-4-090, “Refuse and Recyclables Standards.” For retail developments a minimum of 5 square feet per every 1,000 square feet of building gross floor area shall be provided for recyclable deposit areas and a minimum of 10 square feet per 1,000 square feet of building gross floor area shall be provided for refuse deposit areas with a total minimum area of 100 square feet. For multi-family development, a minimum of 1-½ square feet per dwelling unit shall be provided for recyclable deposit areas, and a minimum of 3 square feet per dwelling unit shall be provided for refuse deposit areas with a combined total minimum area of 80 square feet. The applicant would be required to submit a site plan depicting a refuse and recyclable area compliant with RMC 4-4- 090 with the land use application. Landscaping: Except for 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. Surface parking lots shall contain a perimeter landscaping screen at least 10-feet in width measured from the ROW. Within this perimeter screen trees shall be planted at a minimum of 2- inch caliper at an average rate of 30 lineal feet of street frontage, shrubs at the minimum rate of one per 20 square feet, and groundcover in quantities that will provide at least 90-percent coverage within 3-years. Surface parking lots containing between 15 and 50 stalls shall provide a minimum of 15 square feet of interior parking lot landscaping per stall. Any interior parking lot landscaping area shall be sized to dimensions of at least eight feet (8') by twelve feet (12'). Landscaping shall be dispersed throughout the parking area and shall include a mixture of trees, shrubs, and groundcover. Please refer to landscape regulations (RMC 4-4-070) for additional general and specific landscape requirements. A conceptual landscape plan shall be submitted at the time of land use application. Tree Preservation: If significant trees (greater than 6-inch caliper or 8-caliper inches for alders and cottonwoods) are proposed to be removed, a tree inventory, tree retention plan and worksheet, and arborist report 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 10% of significant Sunset Highlands Mixed Use Preapplication Meeting August 22, 2019 PRE19-000173 trees, and indicate how proposed building footprints would be sited to accommodate preservation of significant trees that would be retained (RMC 4-4-130H1.a). When the required number of protected trees cannot be retained, replacement trees, with at least a two-inch (2") caliper or an evergreen at least six feet (6') tall, shall be planted at a rate of twelve (12) caliper inches of new trees to replace each protected tree removed. 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. 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 20%; significant trees adjacent to critical areas and their associated buffers; and significant trees over 60’ in height or greater than 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 an independent review of any land use application that involves tree removal and land clearing at the City's discretion. A formal tree retention plan and arborist report would be required with the land use application. Parking: Parking for residential units shall be enclosed within the same building as the unit it serves. The following table provides parking ratios for the residential component and two potential commercial uses. Use Ratio Attached Residential Min: 1 space / unit Max: 1.75 spaces / unit Retail Sales Min: 2.5 space / 1,000 SF Max: 5 spaces / 1,000 SF Eating & Drinking Establishments A minimum and maximum of 10 per 1,000 square feet of dining area. The applicant has provided one (1) parking space for each multi-family unit within the building, which meets the minimum quantity and satisfies the parking enclosure requirement. Compliance with the commercial parking requirements would be verified when the specific use is identified. A twenty five percent (25%) reduction or increase from the minimum or maximum number of parking spaces may be granted for nonresidential uses through site plan review if the applicant can justify the modification to the satisfaction of the Administrator. Justification might include, but is not limited to, quantitative information such as sales receipts, documentation of customer frequency, and parking standards of nearby cities. Sunset Highlands Mixed Use Preapplication Meeting August 22, 2019 PRE19-000173 The applicant will be required at the time of formal land use application to provide detailed parking information (i.e. stall and drive aisle dimensions) and calculations of the subject site. Please refer to RMC 4-4-080F.8 and 9 for standard, structured, and compact space requirements and aisle width requirements. The proposal would be required to provide bicycle parking based on 10 % of the required number of parking stalls for commercial uses and one-half (0.5) bicycle parking space per one dwelling unit. The bicycle parking provided for the residents shall provide for secure extended use and shall protect the entire bicycle and its components and accessories from theft and weather. Acceptable examples include bike lockers, bike check-in systems, in-building parking, and limited access fenced areas with weather protection. Spaces within the dwelling units or on balconies do not count toward the bicycle parking requirement. However, designated bicycle parking spaces within individual garages can count toward the minimum requirement. Please review RMC 4-4-080F.10 and RMC 4-4-080F.1 for further general and specific bicycle parking requirements. Access: Driveway widths and quantity are limited by the driveway standards, in RMC 4-4-080I. 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. There shall be no more than one driveway for each one hundred sixty five feet (165') of street frontage serving any one property or among properties under unified ownership or control; for each one hundred sixty five feet (165') of additional street frontage another driveway may be permitted. A connection shall be provided for site-to-site vehicle access ways, where topographically feasible, to allow a smooth flow of traffic across abutting CA zoned lots without the need to use a street. Access may comprise the aisle between rows of parking stalls, but is not allowed between a building and a public street. The proposed two 30-foot wide driveways exceed the number that would be permitted as the site contains only 184-feet of street frontage. An approved modification to the driveway standards would be needed. Existing conditions and critical areas would likely make site-to-site vehicle access ways impractical. Urban Design Regulations: Compliance with Urban Design Regulations, District ‘D’, is required. See RMC 4-3-100 for a menu of options and requirements. The land use application shall identify how the project meets each of the applicable urban design regulations. The following bullets are some, but not all, of the guidelines and standards applicable to your project. 1. Buildings shall be oriented to the street with clear connections to the sidewalk. The front entry of a building shall be oriented to the street or a landscaped pedestrian-only courtyard. 2. Building entries from a street shall be clearly marked with canopies, architectural elements, ornamental lighting, or landscaping and include weather protection at least four and one-half feet (4-1/2') wide along at least seventy five percent (75%) of the length of the building facade facing the street, a maximum height of fifteen feet (15') above the ground elevation, and no lower than eight feet (8') above ground level. Sunset Highlands Mixed Use Preapplication Meeting August 22, 2019 PRE19-000173 3. At least one of the following design elements shall be used to promote a transition to surrounding uses: Building proportions, including step-backs on upper levels in accordance with the surrounding planned and existing land use forms; or Building articulation to divide a larger architectural element into smaller increments; or roof lines, roof pitches, and roof shapes designed to reduce apparent bulk and transition with existing development. 4. In addition to standard enclosure requirements, garbage, recycling collection, and utility areas shall be enclosed on all sides, include a roof and be screened around their perimeter by a wall or fence and have self-closing doors. Service enclosures shall be made of masonry, ornamental metal or wood, or some combination of the three. 5. Parking shall be located so that no surface parking is located between a building and the front property line and shall be located so that it is screened from surrounding streets by buildings, landscaping, and/or gateway features as dictated by location. 6. A pedestrian circulation system of pathways that are clearly delineated and connect buildings, open space, and parking areas with the sidewalk system and abutting properties shall be provided. 7. Architectural elements that incorporate plants, particularly at building entrances, in publicly accessible spaces and at facades along streets, shall be provided. 8. Amenities such as outdoor group seating, benches, transit shelters, fountains, and public art shall be provided. 9. All mixed use residential and attached housing developments of ten (10) or more dwelling units shall provide common open space and/or recreation areas.

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. Critical Areas: Honey Creek is located along the southeast portion of the property. The City’s COR mapping database identifies this reach of Honey Creek as Ns or a non-fish seasonal stream however be advised that portions of the creek have been found to be fish bearing. Ns rated streams require a minimum buffer of 50-feet and a structure setback of 15-feet from the edge of the buffer. Reduction of Ns stream buffers are limited to a 40-foot buffer and the buffer would require enhancement. Buffer width may also be averaged with a minimum width of 25-feet if the total area contained within the buffer after averaging is no less than that contained within the required standard buffer width prior to averaging. Buffer averaging also requires enhancement to the remaining buffer area. A Native Growth Protection Area would be established for the Sunset Highlands Mixed Use Preapplication Meeting August 22, 2019 PRE19-000173 onsite stream and associated buffer as part of the site plan approval process. See RMC 4-3-050I.2 for buffer reduction and averaging criteria. The site plan indicates a stormwater pond or swale within the stream buffer.

Drainage plans and a drainage report complying with the adopted 2017 Renton Surface Water Design Manual (RSWDM) will be required. 2. The site currently undeveloped and is covered by trees and grass. The site gradually slopes away from NE Sunset Boulevard. There is a 12” concrete storm drain along the project along the NE Sunset Boulevard frontage. Reference Project File TED4003643 in COR Maps for record drawings. Honey Creek flows from east to west along the southern frontage of the site. 3. Refer to Figure 1.1.2.A – Flow Chart in the 2017 RSWDM to determine what type of drainage review is required for this site. The site falls within the City’s Flow Control Duration Standard (Forested Conditions). The site falls within the May Creek drainage basin. 4. On-site BMPs satisfying Core Requirement #9 will be required for the site. On-site BMPs shall be evaluated in order of preference by feasibility as described in Section C.1.3 of the 2017 RSWDM. 5. Storm drainage improvements along the NE Sunset Boulevard frontage are required to conform to the City’s street standards. New public and private storm drain shall be designed and sized in accordance with the standards found in Chapter 4 of the 2017 Renton Surface Water Design Manual. 6. The project is in the May Creek basin. Honey Creek, a tributary stream to May Creek is located on and adjacent to the site. The FEMA 100-year floodplain for this stream has not been delineated for this site. The project will need to establish the 100-year floodplain elevation of Honey Creek on the site. A Minor Floodplain Study, as defined in Section 4.4.2.3 of the 2017 Renton Surface Water Design Manual, is required to determine the location of the floodplain and to determine if the project will have filling of the floodplain that would require compensatory storage. The report is also needed to verify that site improvements (on-site roadways and utilities) would not be impacted by flooding and that the lowest floor elevations of buildings in the floodplain are 1’ above the 100-year floodplain elevation. 7. A geotechnical soils report for the site is required per the standards found in Section C.1.3 of the 2017 Renton Surface Water Design Manual. Information on the water table and soil permeability (infiltration rates), with recommendations of appropriate on-site BMPs per Core Requirement #9 and Appendix C shall be included in the report. 8. The development is subject to stormwater system development charges (SDCs). The 2019 stormwater SDC is $0.72 per square foot of new impervious surface but not less than $1,800.00. SDCs are due at the time of construction permit issuance. TRANSPORTATION/STREET COMMENTS Sunset Highlands Mixed Use – PRE19-000173 August 22, 2019 1.
