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 online at https://www.codepublishing.com/WA/Renton/. Project Proposal: The applicant is proposing to subdivide two existing parcels into two (2) lots and one tract. The subject properties proposed for subdivision are located at 13825 156th Ave SE near the intersection of 156th Ave SE and SE 4th Pl (APN 1463400057 and 146340UINT). The parcels total approximately 1.1 acres in size. Based on information in COR Maps, APN 146340UINT is a tract created prior to annexation of the land into the City of Renton in 2008 (Liberty Annexation). An existing home is located on the non-tract parcel (also annexed in 2008) and is proposed for removal as part of the project. Ownership of the tract could not be confirmed via the King County Assessor’s database. The site has a Comprehensive Plan Land Use of Designation of Residential Low Density (RLD) and a zoning designation of Residential-4 (R-4) dwelling units per net acre (du/ac). The size of the proposed lots are approximately 33,814 SF and 10,212 SF. The applicant has proposed the establishment of a new shared driveway within the existing tract in order to access the two proposed lots. According to COR Maps, no critical areas are present on the project site. The applicant did not indicate the proposed removal of any trees or vegetation on the project site; however, some removal is expected based on the site layout. Current Use: The site is currently developed with a single-family home and detached garage/shop. Zoning/Density Requirements: The subject property is located within the R-4 zoning classification. A maximum of 4.0 dwelling units per acre is allowed in the R-4 zone. There is no minimum density for the R-4 zone. The Residential Low Density Land Use designation is intended to provide transition to the rural area, or those appropriate for larger lot housing within the Residential Low Density (RLD) land use designation to allow for a range of lifestyles. The area of public and private streets (including driveway tracts) and critical areas (excluding buffers) 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 lots would have a net density of approximately 2 du/ac (2 units/1 ac = 2 du/ac). 8 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 applicati on (noted as “R-4 standards” herein) Minimum Lot Size, Width and Depth – The minimum lot size permitted in the R-4 zone, is 9,000 square feet for parcels being subdivided. Minimum lot width is 70 feet for interior lots and 80 feet for corner lots; minimum lot depth is 100 feet. Both proposed lots appear to meet the minimum size and depth requirements for the R-4 zone. However, Lot 1 is classified as a corner lot due to having frontage on both a public ROW (156 th St SE) and a driveway tract (or required half street improvement; see “Access” section below for additional info). Therefore Lot 1 would be required to have a lot width of at least 80 feet. Lot 2 appears to comply with all lot dimensional standards. 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 land use application. Building Standards – The R-4 standards allow a maximum building coverage of 35% of the lot area. The maximum impervious coverage in the R-4 zone is 50%. The maximum wall plate height is restricted to 32 feet, and the buildings shall be not more than three 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 for the new building 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-4 zone are: Front yard: 30 feet for the primary structure; Rear yard: 25 feet; Side yards: 20 feet combined (minimum of 7.5 feet on either side); and Secondary Front yard: 30 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. The setbacks would be measured from the new property lines after roadway dedication. Lot 1 shall be subject to corner lot Access/Parking: Access to the lots is proposed via a driveway tract within the existing tract to the north of the primary parcel. However, the City of Renton Future Roads Maps indicates that a new residential access street (53 foot width) is planned along the north side of the site. The plan requires a through road at the north property line that would extend to SE 4th Place. Therefore the project would be required to provide half street residential access road improvements along the entire north side of the site. The half street would require a dedication width of approximately 37 feet. For additional info on dedication and required improvements, please see the Development Engineering comments above under the “Transportation” section. Any driveway shall be setback at least 5 feet from the side lot lines (unless utilizing a joint driveway). 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. 9 Storm drainage facilities are required to comply with the minimum 15-foot perimeter landscaping strip on the outside of the fence unless otherwise determined through the site plan review or subdivision review process. Please refer to landscape regulations RMC 4-4-070 for further general and specific landscape requirements. 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: According to COR Maps, no critical areas are located on the project. However, it is the applicant’s responsibility to ascertain whether any critical areas are present on the site. Environmental Review: Projects consisting of nine (9) units or less and that will not impact a critical area are exempt from Environmental (SEPA) Review. Based on the proposal submitted by the applicant, the proposed project would be exempt from SEPA review. Permit Requirements: The proposal would require administrative short plat approval. The 2020 administrative short plat application fee is $5,544 ($5,280 plus a 5% Technology Surcharge Fee). All fees are subject to change. The applications would be reviewed concurrently within an estimated time frame of six to eight weeks. Detailed information regarding the land use application submittal can be found on the City’s permitting page at permitting.rentonwa.gov and clicking on “Land Use”, then “All Forms (A to Z).” The City now requires electronic plan submittal for all applications. Once Preliminary Short Plat approval is obtained, the applicant must complete the required improvements and dedications, as well as satisfy any conditions of the preliminary approval before submitting for Final Short Plat review. Once final approval is received, the plat may be recorded. The newly created lots may only be sold after the plat has been recorded. In addition to the required land use permits, separate construction and building permits would be required. 10 Public Notice: A minimum of one Public Information Sign is required for a Short Plat application. The applicant is responsible for the procurement, installation and maintenance of the sign. Detailed information regarding the land use application submittal requirements is provided on the City of Renton website (www.rentonwa.gov). Fees: In addition to the applicable building and construction fees, impact fees would be required. Such fees would apply to all projects and would be calculated at the time of building permit application and payable prior to building permit issuance. The 2020 impact fees are as follows:  A Transportation Impact Fee based on $7,820.42 per each new detached dwelling unit.  A Parks Impact Fee based on $3,945.07 per each new detached dwelling unit.  A Fire Impact fee of $829.77 per each new detached dwelling unit.  A Renton School District Impact Fee of $6,877.00 (+5% administrative fee) per each new detached dwelling unit.
