DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: April 17th, 2018 TO: Pre-Application File No. 18-000222 FROM: Alex Morganroth, Associate Planner SUBJECT: Gorban Short Plat Parcel #3343901360 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 applicant is proposing to subdivide an existing parcel into two lots. The subject property is located at 2213 NE 28th St near the intersection of NE 28th St and Blaine Ave NE (APN 3343901360). The project site totals 17,913 square feet (0.41 acres) in area and is currently developed with a single-family home and associated accessory structure. The site has a Comprehensive Plan Land Use of Designation of Residential Medium Density and a zoning designation of Residential-8 (R-8) dwelling units per net acre (du/ac). The applicant is proposing to demolish the existing home and construct one detached single-family home on each of the new lots. The size of proposed Lot 1 is 10,150 square feet and the size of proposed Lot 2 is 8,141 square feet (Note: there is an inconsistency between total parcel size and lot sizes proposed by applicant). Access to both lots is proposed via driveways off of NE 28th St. The Wellhead Protection Area Zone 2 is mapped on the project site. The applicant has not proposed the removal any trees or vegetation on the site. Current Use: The project site is currently developed with a single-family home and associated accessory structure. 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 one net acre. The Residential Medium Density Land Use designation is intended to create opportunities for new single family residential neighborhoods and to facilitate high-quality infill development that promotes reinvestment in existing single family neighborhoods. Detached single family residential dwelling units are permitted uses within the R-8 zoning designation. The area of public and private streets (including driveway tracts) 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. As proposed, the two new lots would have a gross density of approximately 4.87 du/ac. Compliance with the density standards would be required to be demonstrated at the time of formal land use 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 (noted as “R-8 standards” herein) Minimum Lot Size, Width and Depth – The minimum lot size permitted in the R-8 zone, is 5,000 square feet for parcels being subdivided. Minimum lot width is 50 feet for interior lots and 60 feet for corner lots; minimum lot depth is 80 feet. Please note that for short plats of parcels smaller than one acre, one parcel may be allowed to be smaller than the required minimum lot size, if all other parcels meet the required minimum lot size standard of the zone. In the R-8 zone, one parcel may be allowed to be four thousand five hundred (4,500) square feet. As proposed, the lots appear to meet the requirements for the R-8 zone. It is the applicant’s responsibility to demonstrate compliance with the minimum lot size, width and depth criteria of the zone at the time of formal application. Building Standards – The R-8 standards allow a maximum building coverage of 50% of the lot area. The maximum impervious coverage in the R-8 zone is 65%. The maximum wall plate height is restricted to 24 feet, and the buildings shall be not more than two stories. 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; common rooftop features, such as chimneys, may project an additional four (4) vertical feet from the roof surface. Non-exempt vertical projections (e.g., decks, railings, etc.) shall not extend above the maximum wall plate height unless the projection is stepped back one-and-a-half (1.5) horizontal feet from each façade for each one (1) vertical foot above the maximum wall plate height. Detached accessory structures must remain below a height of 15 feet. The gross floor area must be less than that of the primary structure. Accessory structures are also included in building lot coverage calculations. Compliance with the building standards would be required to be demonstrated at the time of building permit review. Setbacks – Setbacks are the minimum required distance between the building footprint and the property line. The required setbacks for the R-8 zone are: Front yard: 20 feet for the primary structure; Rear yard: 20 feet; Side yards: 5 feet; and Secondary Front yard: 15 feet. Corner lots required to have a front yard and a secondary front yard are relieved of the requirement to have a rear yard; in place of a rear yard setback, the side yard setback of the zone shall apply. Access/Parking: Access to the lots is proposed to be gained via separate driveways off NE 28th St. Each lot is required to accommodate off street parking for a minimum of two vehicles. 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. 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. Landscaping: With the exception of critical areas, all pervious area shall have landscape treatment. Landscaping may include hardscape such as decorative paving, rock outcroppings, fountains, plant containers, etc. Ten feet (10') of on-site landscaping is required along all public street frontages. Where there is insufficient right-of-way space or no public frontage, street trees are required in the front yard subject to approval of the Administrator. A minimum of two (2) trees are to be located in the front yard prior to final inspection. A conceptual landscape plan shall be provided with the formal land use application as prepared by a registered Landscape Architect or other certified professional. Significant Tree Retention: If significant trees 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 percent (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, the lot would be required to provide a minimum tree density of 2 trees per 5,000 square feet of lot area onsite. 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 formal tree retention plan prepared by an arborist or landscape architect would be reviewed at the time of the formal land use application if any trees are proposed for removal. Critical Areas: The project site is located within the Wellhead Protection Area Zone 2. If any fill is proposed to be brought on the project site, the applicant shall provide a fill source statement to ensure against accidental contamination of the aquifer. It is the applicant’s responsibility to ascertain whether any additional critical areas or environmental concerns are present on the site during site development or building construction. Environmental Review: The project is Categorically Exempt from Environmental (SEPA) Review. 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 administrative short plat application fee is $5,250.00 ($5,000.00 each plus a 5% Technology Surcharge Fee). Each modification request is $262.50 ($250.00 each plus a 5% Technology Surcharge Fee). All fees are subject to change.
