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 linked here and available online at www.rentonwa.gov Project Proposal: The project site (APN 102305-9133) is located at 1051 Chelan Ave NE and totals approximately 46,609 square feet (1.07 acres) in area and is zoned Residential-8 (R-8). The applicant proposes is to subdivide the existing parcel into six (6) single-family lots. The narrative indicates lot size ranges from 5,000 to 6,000 square feet. Access to the proposed lots would be provided via a two (2) abutting shared driveway tracts extending from Chelan Ave NE. Previous wetland studies indicate a Category III wetland is located on the abutting northern property Current Use: The property is developed with an existing single family home. It appears from the short plat drawing that the existing single family home would be removed. Zoning/Density Requirements: The subject property is zoned Residential-8 (R-8). The minimum density in the R-8 zone is 4.0 dwelling units per net acre (du/ac) and the maximum density is 8.0 du/ac. Private access easements, critical areas (except buffers), and public right-of-way are excluded from the total area to determine net density. Alleys (public or private) are not excluded. The applicant would be required to demonstrate compliance with the net density requirements of the zone at the time of prior to the City accepting the short plat application for review. A completed Density Worksheet will be required with the master application. Development Standards: The project would be subject to RMC 4-2-110A, “Development Standards for Residential Zoning Designations (Primary Structures)” effective at the time of complete application. Please refer to this code section in its entirety when preparing application submittal materials. The following are some of the standards that would apply to your proposal: 9 Chelan Street Short Plat Preapplication Meeting March 12, 2020 R-8 Development Standards Minimum Lot Size 5,000 square feet Minimum Lot Width 50-feet Minimum Lot Width (Corner Lots)60-feet Minimum Lot Depth 80-feet Minimum Front Yard 20-feet or 15-feet with alley access Minimum Secondary Front Yard (Corner Lots)15-feet Minimum Rear Yard 20-feet (corner lots utilize the side yard setback in place of the rear yard) Minimum Side Yard 5-feet Maximum Building Coverage 50-percent Maximum Impervious Surface Area 65-percent Maximum Height Two stories and maximum wall plate height of 24-feet. 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. Minimum Tree Density 2 significant trees per 5,000 sf. of lot area Lots do not appear to meet width or depth requirements. Proposed building footprints do not appear to meet setbacks. Front yard setbacks for Lots 1, 2, 4, and 5 appear to be 10-feet. Setback compliance would be verified at the time of single family building permit review. Building coverage, impervious surface, height requirements would be verified at the time of single family building permit review. Residential Design Standards: New homes within the subdivision would be subject to the Residential Design Standards outlined in RMC 4-2-115. Key characteristics of the design standards include a variety of housing architectural styles, enhanced by attention to selection of exterior materials, colors, architectural detailing, and ensuring that garages do not visually dominate the streetscape. The proposal’s compliance with the residential design standards would be verified at the time of building permit review. 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 (private side) is 10 feet and shall contain trees, shrubs, and landscaping. The applicant would also be required to provide planting in the 8-foot wide landscape strip between the curb and sidewalk with groundcover and a minimum of one (1) street tree per new lot along the newly constructed Chelan Ave NE frontage. A 15-foot perimeter landscaping screen is required around any storm drainage facility. A conceptual landscape plan would be required to be submitted with the land use application. 10 Chelan Street Short Plat Preapplication Meeting March 12, 2020 Significant Tree Retention: If significant trees (greater than 6-inch caliper or 8-caliper inches for alders and cottonwoods) are proposed to be removed, a Tree Retention/ Land Clearing (Tree Inventory) Plan, arborist report, and tree retention worksheet shall be provided with the master 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. Tree retention standards shall be applied to the developable area of a property (i.e., land within critical areas and their buffers, public rights-of-way, private PUD streets, shared driveways, and public trails shall be excluded). If the number to be retained includes a fraction of a tree, any amount equal to or greater than one-half (1/2) tree shall be rounded up. 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. In addition to retaining 30% of existing significant trees, each newly created lot would be required to provide a minimum tree density of 2 trees per 5,000 square feet of lot area onsite. Protected trees that do not contribute to a lot's required minimum tree density shall be held in perpetuity within a tree protection tract. 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. A tree retention plan prepared by an arborist or landscape architect would be reviewed at the time of land use application. 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 and 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. Retaining wall heights for residential development are limited to 6-feet in height for interior side yards and rear yards and 4-feet in height front yards and side or rear yards along a street. Terrace widths must be equal to the wall height and landscaped. Retaining walls shall be 11 Chelan Street Short Plat Preapplication Meeting March 12, 2020 composed of brick, rock, textured or patterned concrete, or other masonry product that compliments the proposed building and site development. Access: Access to the proposed lots is shown as two (2) abutting shared driveway tracts each serving three (3) lots with no turnaround. The City would not permit to abutting shared driveway tracts and a public street would be required to serve six (6) lots. Shared driveways may be considered by the City for access to four (4) or fewer lots, provided: 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; The subject lots are not created by a subdivision of ten (10) or more lots; 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; The shared driveway would not adversely affect future circulation to neighboring properties; The shared driveway is no more than three hundred feet (300') in length; and The shared driveway poses no safety risk and provides sufficient access for emergency vehicles and personnel.

Critical Areas: A wetland delineation report was prepared by The Watershed Company dated September 30, 2019 indicates that a Category III wetland is located just north of the subject property. Category III wetlands require a 100-foot buffer and 15-foot building setback from that buffer. The buffer and setback will affect the western portion of the subject property. A native growth protection area would be required to be instituted to protect the critical area from development. This area would be required to be placed within a tract via the short plat with a covenant and deed restriction that prohibits any development, alteration, or disturbance within the native growth protection area. The short plat will be required to provide a tract for the delineated wetland buffer. It is the applicant’s responsibility to ascertain whether any additional critical areas or environmental concerns are present on the subject property prior to site development or building construction. Environmental Review: Typically short plats are exempt from State Environmental Policy Act (SEPA) review, however due to the wetland buffer located on the subject property an environmental checklist must be submitted with the short plat application. A threshold determination will be issued prior to or concurrently with the short plat decision. 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 2020 administrative short plat application fee is $5,544.00 ($5,280.00 plus a 5% Technology Surcharge Fee) and the environmental checklist fee is $1,659.00 ($1,580.00 plus 5% Technology Surcharge Fee).
