DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: March 19, 2015 June 20, 2011 TO: Clark Close, Associate Planner FROM: Vicki Grover, Plan Review SUBJECT: Khnor Short Plat 1012 Duvall Avenue NE PRE14-000126 NOTE: The applicant is cautioned that information contained in this summary is preliminary and non- binding and may be subject to modification and/or concurrence by official City decision-makers. 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. I have completed a preliminary review for the above-referenced proposal. The following comments are based on the pre-application submittal made to the City of Renton by the applicant. WATER The proposed development is within the City’s retail water service area in the Highlands 565-zone. There is an existing 8-inch City water main (see water plan no. W-3386) ending along the south property line. There is also an existing 8-inch water main (see water plan no. W-3325) in Chelan Ave NE. The available flow rate is 1,250 gallon per minute and the static water pressure is about 55 psi at ground elevation 435 feet. King County Water District No. 90 (WD 90) currently has a 4-inch water main located within an easement along the west side of the development that is serving existing properties to the north of the development. The existing water main must be protected during the construction of roadway and utilities improvements required for the short-plat. Since the property is within the retail water service of the City of Renton, any development or redevelopment of the property must be served by through an extension of the City’s water system. As such the following water main improvements will be required and as shown on the attached conceptual water layout: 1. Extension of an 8-inch water main within the new west/east access road connecting to the existing 8-inch water main (W-3325) in Chelan Ave NE. 2. Extension of an 8-inch water main within the new north/south access road connecting to the above new water main and also to the existing 8-inch water main (W-3386) south of the development and extending to the north property line.

H:\CED\Planning\Current Planning\PREAPPS\15-000126 DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: March 19, 2015 TO: Pre-Application File No. 15-000126 FROM: Clark H. Close, Associate Planner SUBJECT: Khnor Short Plat – 1012 Duvall Ave NE 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, 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 $50.00 plus tax from the Finance Division on the first floor of City Hall or online at www.rentonwa.gov. Project Proposal: The subject properties are located in the Highlands Planning Area of Renton near the intersection of Duvall Ave NE and NE 10th St at 1012 Duvall Ave NE (APN 102305-9139). The applicant is proposing to short plat a 1.32-acre parcel of vacant land into 8 single family lots. The site has a Comprehensive Plan Land Use of Designation of Residential Single Family (RS) and a zoning designation of Residential-8 (R-8) dwelling units per net acre (du/ac). The short plat is intended for the eventual development of eight (8) new detached single-family homes. The applicant is proposing to access all eight (8) lots from Chelan Ave NE via a 43-foot right-of-way followed by a 90-foot long hammerhead turnaround. The drainage from the project area is proposed to be collected by a new conveyance system to the existing storm system in NE 10th Street and discharge into an existing pond about 150 feet west of Chelan Ave NE. Current Use: The parcel is vacant land. Grass lawn and underbrush mainly covers the site. Zoning/Density Requirements: The subject property is located within the R-8 zoning classification. The density range allowed in the R-8 zone is a minimum of 4.0 to a maximum of 8.0 dwelling units per 1 net acre. 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. In order to calculate the proposed density of the project, any area of public road, private easement, and/or critical area dedication must be known. Using the gross square footage, the 8-lot proposal arrives at a gross density of approximately 6.06 du/ac (8 lots / 1.32 acres = 6.06 du/ac). It is unclear exactly how much area would be required to be dedicated for right-of-way; therefore, the net density of site could not be calculated. A Density Worksheet Khnor Short Plat, PRE15-000126 Page 2 of 6 March 19, 2015 H:\CED\Planning\Current Planning\PREAPPS\15-000126 would be required at the time of formal short plat 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 gross density of 6.06 du/ac, the subject site would meet the minimum density requirements of the zone. On September 22, 2014, the City of Renton adopted interim zoning prior to the Comprehensive Plan update process (Ordinance No. 5724). The purpose of the interim zoning ordinance is to continue to permit new development in a manner that improves the compatibility of new development with existing development in the surrounding community and with potential changes in zoning code and to allow the City adequate time to consider and develop new zoning code regulations as well as potential rezones of some areas. Washington State law enables cities to exercise this type of zoning on a limited basis. The development standards for residential development are as follows: R-8 (old standards) Interim Zoning (current standards) Minimum Lot Area 4,500 sf for parcels greater than 1 acre. 5,000 sf for parcels 1 acre or less. 7,000 sq. ft. Minimum Lot Width 50 ft. 60 ft. Minimum Lot Width (corner lots) 60 ft. 70 ft. Minimum Lot Depth 65 ft. 90 ft. Front Setback 15 ft. 25 ft. Rear Setback 20 ft. 25 ft. Side Setback 5 ft. 15 ft. combined with a min, of 5 ft. (per CI-64) Side Setback (along a street) 15 ft. 25 ft. (per CI-64) Maximum Height 30 ft. 30 ft. Maximum Building Coverage (including Primary and Accessory) 50% 40% Maximum impervious surface 75% 55% Development Standards: The project would also be subject to RMC 4-2-110A, “Development Standards for Single Family Zoning Designations” and interim zoning effective at the time of complete application (noted as R-8 standards herein). Single family residential development is permitted outright in the R-8 zone. Minimum Lot Size, Width and Depth – The current minimum lot size permitted in the R-8 zone is 7,000 square feet for all parcels. A minimum lot width of 60 feet for interior lots and 70 feet for corner lots, as well as a minimum lot depth of 90 feet, is also required. The applicant would be required to demonstrate compliance with lot size, width and depth of the zone at the time of formal application. Building Standards – R-8 zone allows a maximum building coverage of 40%. The maximum impervious coverage in the R-8 zone is 55%. Building height is restricted to 30 feet from existing grade. Detached non-residential accessory structures must remain below a height of 15 feet. The gross floor area of accessory structures must be less than that of the primary structure. Khnor Short Plat, PRE15-000126 Page 3 of 6 March 19, 2015 H:\CED\Planning\Current Planning\PREAPPS\15-000126 Accessory structures are also included in building lot coverage calculations. The proposal’s compliance with the building standards would be verified at the time of building permit review for the new residences. Setbacks – Setbacks are the minimum required distance between the building footprint and the property line and any private access easement. The current required setbacks in the R-8 zone are 25 feet in front for the primary structure, 25 feet in the rear, 15 feet combined with a minimum of 5 feet for interior side yards, and 25 feet on side yards along streets. Setbacks would be vested at time of complete Short Plat application submittal. The setbacks for the new residences would be reviewed at the time of building permit. Residential Design and Open Space Standards: All new dwelling units in the Residential Eight Dwelling Units per Acre (R-8) zone are subject to the Residential Design and Open Space Standards outlined in RMC 4-2-115. The proposal’s compliance with the residential design standards would be verified at the time of building permit review for the new residences to be located on all new lots. Lot Configuration – One of the following is required: 1. Lot width variation of 10 feet (10') minimum of one per four (4) abutting street-fronting lots, or 2. Minimum of four (4) lot sizes (minimum of 400 gross square feet size difference), or 3. A front yard setback variation of at least five feet (5') minimum for at least every four (4) abutting street fronting lots. Based on the submitted application lot configuration standard #1 above has been met. 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 façades 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. Khnor Short Plat, PRE15-000126 Page 4 of 6 March 19, 2015 H:\CED\Planning\Current Planning\PREAPPS\15-000126 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: Vehicular access to the proposed new lots is proposed from Chelan Ave NE. Residential access improvements include extending Chelan Pl NE (a 20-foot right-of-way road) to the north property line and completing a limited residential access road (45-foot right-of-way width in order to meet the City’s complete street standards requirements) between Chelan Pl NE and Chelan Ave NE. Two off-street parking spaces are required for each primary residence. The maximum width of single loaded garage driveways shall not exceed nine feet (9') and double loaded garage driveways shall not exceed sixteen feet (16'). Driveways: The project site is generally flat with runoff flows from northeast corner of the property to the southwest corner of the property with an average slope of about 6.0%. Driveways exceeding 8% must provide slotted drains at the lower end of the driveway. The maximum grade for the shared driveway shall not exceed fifteen percent (15%). Landscaping and Open Space: Ten feet (10') of onsite landscaping is required along all public street frontages, with the exception of areas for required walkways and driveways according to the landscaping standards of RMC 4-4-070F. Such landscaping shall include a mixture of trees, shrubs, and groundcover as approved by the Department of Community and Economic Development. Minimum planting strip widths between the curb and sidewalk are established according to the street development standards of RMC 4-6-060. Street trees and, at a minimum, groundcover are to be located in this area when present. Street tree spacing standards shall be as stipulated by the Department of Community and Economic Development, provided there shall be a minimum of one street tree planted per address. Any additional undeveloped right-of-way areas shall be landscaped unless otherwise determined by the Administrator of the Department of Community and Economic Development or designee. Broadleaf trees planted in residential zones must be a minimum of one and one-half inches (1.5") in diameter (dbh). Conifer trees at the time of planting must be fully branched and a minimum of six feet (6') in height. A conceptual landscape plan must be provided with the formal land use application as prepared by a registered Landscape Architect, a certified nurseryman or other certified professional. The plan shall include, but is not limited to, the minimum 10-foot onsite landscaping strip and street trees within the planting strip of each lot. Khnor Short Plat, PRE15-000126 Page 5 of 6 March 19, 2015 H:\CED\Planning\Current Planning\PREAPPS\15-000126 Significant Tree Retention: If significant trees (greater than 6-inch caliper) are proposed to be removed, a tree inventory and a tree retention plan along with a tree retention worksheet shall be provided with the formal land use application. The tree retention plan must show preservation of at least 30% of significant trees, and indicate how proposed building footprints would be sited to accommodate preservation of significant trees that would be retained. 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 new lot would be required to provide a minimum tree density of 2 trees per 5,000 square feet (or the gross equivalent of caliper inches provided by one or more trees) 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 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 independent review of any land use application that involves tree removal and land clearing at the City's discretion. See recently adopted Ordinance 5748 for details. A formal tree retention plan would be reviewed at the time of Short Plat 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 or grading plan. A fence and/or wall detail should also be included on the plan as well. A fence taller than six feet (6') shall require a building permit or an explicit exemption from the Building Official. A retaining wall that is four feet (4') 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 see RMC 4-4-040. Critical Areas: The City of Renton maps does not indicate that regulated critical areas are located on the site. It is the applicant’s responsibility to ascertain whether critical areas or environmental concerns are present on the site during site development or building construction. Environmental Review: Except when located in sensitive areas (such as wetlands) or lands covered by water, short plats of nine or fewer lots are categorically exempt from Environmental (SEPA) Review. Permit Requirements: The proposal would require approval of an administrative short plat and Environmental (SEPA) Review. The administrative short plat request would be reviewed within an estimated time frame of six to eight weeks. The Short Plat application fee is $2,000.00 Khnor Short Plat, PRE15-000126 Page 6 of 6 March 19, 2015 H:\CED\Planning\Current Planning\PREAPPS\15-000126 ($2,000.00 plus 3% Technology Surcharge Fee).
