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 for purchase for $100.00 plus tax, from the Finance Division on the first floor of City Hall or online at www.rentonwa.gov Project Proposal: The subject property is located at 1415 North 24th Street (APN 3344500234). The project site has a small gently sloped area on a primarily flat lot. The property is zoned Residential – 8 dwelling units per acre and is between 21,406 square feet and 23,595 square feet (see Zoning/Density section, below) in size. The applicant is proposing to subdivide the property into 4 lots. Each proposed new lot would be approximately 5,200 square feet in size. An existing house would be demolished to accommodate the proposed subdivision. Vehicular access to Proposed Lots 1 and 2 would be via new driveways from North 24th Street; access to Proposed Lots 3 and 4 would be via a new access easement through Proposed Lots 1 and 2 from North 24th Street. Current Use: The property is developed with an existing 2,140 square foot single-family house (to be removed). Zoning/Density Requirements: The subject property is zoned Residential-8 dwelling units per acre (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 and public right-of-way dedications are deducted from the total area to determine net density. The net acreage of the site based on the applicant’s submitted dimensions is 0.47 acres (22,240 gross square feet – 1,600 access easement square feet = 20,649 net square feet or 0.47 acres). The net density of the proposed project would be 8.51 du/ac which is not in conformance with the density range of the R-8 zone. Staff recommends that the applicant consider revising the proposal to a 3-lot short plat to comply with the density standard. Please note that the applicant has shown the proposed site as 22,240 square feet, Kroll Maps indicate that the site encompasses 21,406 square feet, and the King County Assessor indicates that the site encompasses 23,595 square feet. The formal application must contain a survey prepared by a licensed surveyor which indicates accurate dimensions. Density will be verified at the time of formal application. Development Standards: The project would be subject to RMC 4-2-110A, “Development Standards for Single Family Zoning Designations” effective at the time of complete application. A copy of these standards is included. Minimum Lot Size, Width and Depth – The minimum lot size permitted in Zone R-8 is 5,000 square feet for parcels less than one acre. Minimum lot width for interior lots is 50 feet and minimum lot depth is 65 feet. As shown on the submitted site plan the proposal meets the minimum lot size and width requirements. However, because the proposal is above the maximum net density, staff will evaluate the minimum lot size, width and depth at such time as the proposal is revised. Building Standards – The R-8 zone allows a maximum building coverage of 35% of the lot area or 2,500 square feet, whichever is greater for lots over 5,000 square feet in size. The maximum impervious coverage in the R-8 zone is 75%. Building height is restricted to 30 feet. Detached accessory structures must remain below a height of 15 feet and one-story. Accessory structures are also included in building lot coverage calculations. Compliance with building standards will be determined at the time of building permit review for any new structures. Setbacks – Setbacks are the minimum required distance between the building footprint and the property line and any private access easement. The required setbacks in the Zone R-8 are: Front yard – 15 feet for the primary structure. The front yard of Proposed Lots 1 and 2 would be along North 24th Street and the front yard for Proposed Lots 3 and 4 would face North 24th Street. Proposed Lots 1 and 2 indicate a 20-foot front yard setback. Rear yard – 20 feet. The proposed submittal indicates a 15-foot rear yard setback. The area required is actually a minimum of 20 feet for the rear yard, therefore, the building envelope would need to be redrawn. The rear yard shown for Lots 3 and 4 appears to be 20 feet, however a 5-foot typical dimension is shown along the rear lot line. This would need to be corrected prior to submittal. Side yards – 5-feet, except 15-feet for side yards along a street. The access easement providing access to the rear of the site will likely be treated as a side yard along a street easement, requiring a 15-foot setback for houses from the edge of the easement. Setbacks will be verified at the time of formal short plat application. Residential Design and Open Space Standards: The Residential Design and Open Space Standards contained in RMC 4-2-1215 would be applicable to any new residential structures. A handout indicating the applicable guidelines and standards is enclosed. As applicable to the R-8 zone, the guidelines are: Garages – The visual impact of garages shall be minimized, while porches and front doors shall be the emphasis of the front of the home. Garages shall be located in a manner that minimizes the presence of the garages and shall not be located at the end of view corridors. Alleyway access is encouraged. If used, shared garages shall be within an acceptable walking distance to the housing unit it is intended to serve. Primary Entry – Entrances to homes shall be a focal point and allow space for social interaction. Front doors shall face the street and be on the façade closest to the street. When a home is located on a corner lot (i.e. at the intersection of two roads or the intersection of a road and a common space) a feature like a wraparound porch shall be used to reduce the perceived scale of the house and engage the street or open space on both sides. Façade Modulation – Buildings shall not have monotonous facades along public areas. Dwellings shall include articulation along public frontages; the articulation may include the connection of an open porch to the building, a dormer facing the street, or a well-defined entry element. Windows and Doors – Windows and front doors shall serve as an integral part of the character of the home. Primary windows shall be proportioned vertically rather than horizontally. Vertical windows may be combined together to create a larger window area. Front doors shall be a focal point of the dwelling and be in scale with the home. All doors shall be of the same character as the home. Scale, Bulk, and Character –A diverse streetscape shall be provided by using elevations and models that demonstrate a variety of floor plans, home sizes, and character. Neighborhoods shall have a variety of home sizes and character. Roofs – Roofs shall represent a variety of forms and profiles that add character and relief to the landscape of the neighborhood. The use of bright colors, as well as, roofing that is made of material like gravel and/or reflective material is discouraged. Eaves – Eaves should be detailed and proportioned to complement the architectural style of the home. Architectural Detailing – Architectural detail shall be provided that is appropriate to the architectural character of the home. Detailing like trim, columns, and/or corner boards shall reflect the architectural character of the house. Materials and Color – A diversity of materials and color shall be used on homes throughout the community. A variety of materials that are appropriate to the architectural character of the neighborhood shall be used. A diverse palette of colors shall be used to reduce monotony of color or tone. Access/Parking: The applicant has indicated that access would be taken via two new driveways for Proposed Lots 1 and 2 and via a new access easement driveway for Proposed Lots 3 and 4 from North 24th Street. Staff prefers that all lots take access from one access easement. Two lots of the suggested 3-lot short plat should front on North 24th Street with side loaded garages. Critical Areas: The project site is located in Aquifer Protection Zone 2. Environmental Review: The proposed project is categorically exempt from Environmental (SEPA) Review. Permit Requirements: The proposal would require approval of an administrative short plat. The administrative short plat request would be reviewed within an estimated time frame of 6 to 8 weeks. The fee for a short plat application is $1,442.00 ($1,400.00 plus 3% Technology Surcharge Fee). Detailed information regarding the land use application submittal is provided in the attached handouts. Impact/Mitigation Fees: In addition to the applicable construction and building permit fees, the following mitigation fees would be required prior to issuance of building permits. Impact fees, which would replace mitigation fees, may be adopted prior to building permit approval for which an applicant may vest to impact/mitigation fees. Those fees have yet to be determined. Currently fees are the following: A Transportation Mitigation Fee based on $75.00 per each new average daily trip attributable to the project; A Fire Mitigation Fee based on $488.00 per new single-family residence; and, A Renton School District Impact fee based on $6,310.00 per each new single-family residence and is payable prior to issuance of building permits. For 4 lots, a Parks Mitigation Fee based on $530.76 per new single family residence. A handout listing all of the City’s Development related fees is attached for your review. Expiration: Upon approval, the short plat is valid for two years with a possible one year extension.
