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 property is located on the west side of 114th Ave SE just south of SE 162nd St at 16217 114th Ave SE. The proposal is to subdivide the existing parcel into 3 lots for the future construction of single family residences. In addition the applicant is proposing a reduction in the lot width requirements for Lots 1 and 2. The subject property totals 16,897 square feet in area, and is zoned Residential-8 dwelling units per net acre (R-8). Access to the site would be gained via proposed driveways from 114th Ave SE. There appear to be sensitive slopes located on site. Current Use: The site is currently contains a single family residences proposed for demolition. Zoning/Density Requirements: The subject property is located within the R-8 zoning designation. The density range allowed in the R-8 zone is a minimum of 4.0 to a maximum of 8.0 dwelling units per acre (du/ac). The area located within the proposed access easement would be deducted from the gross site area to determine the “net” site area prior to calculating density. With a 16,897 square foot site area , the proposal would arrive at a net density of 7.73 dwelling units per acre (3 units / 0.388 acre = 7.73 du/ac which is within the density range of the zoning classification. 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 is 4,500 square feet for parcels greater than 1 acre in size and 5,000 square feet for lots 1 acre or less in size. Lund Short Plat, PRE12-068 Page 2 of 3 September 6, 2012 i:\rtimmons\preapps\12-068 (r-8 shpl lot width ).doc The total lot area of the subject site is less than 1 acre; therefore a minimum lot size of 5,000 square feet is applicable to the proposed project. A minimum lot width of 50 feet for interior lots and 60 feet for corner lots, as well as a minimum lot depth of 65 feet, is also required. The proposal does not comply with the lot width standards of the zone. The applicant would be required to apply for and have granted an Administrative Variance in order to reduce the lot width for proposed Lots 1 and 2 from 50 to 40 feet. At this time it does not appear the applicant would meet all variance criteria and a lot width variance is likely to not be supported. Building Standards – 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. Building height is restricted to 30 feet from existing grade. 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. The proposal’s compliance with the building standards would be verified at the time of building permit review for the new residences to be located on all lots. 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 R-8 zone are 15 feet in front for the primary structure and 20 feet in front for the attached garage, 20 feet in the rear, 5 feet on interior side yards, and 15 feet on side yards along streets (including access easements) for the primary structure and 20 feet on side yards along streets (including access easements) for the attached garage. The setbacks for the new residences would be reviewed at the time of building permit. Building Design Standards – The proposed structure would be subject to the Residential Design 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. Access/Parking: Access to the proposed lots would be provided via private driveways extended from 114th Ave SE. Each lot is required to accommodate off street parking for a minimum of two vehicles. Driveways: The maximum driveway slopes cannot exceed 15%, provided that driveways exceeding 8% are to provide slotted drains at the lower end of the driveway. If the grade exceeds 15%, a variance is required. 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 development standards require that all pervious areas within the property boundaries be landscaped. The minimum on-site landscape width required along street frontages is 10 feet. Please refer to landscape regulations (RMC 4-4-070) for further general and specific landscape requirements (enclosed). A conceptual landscape plan shall be submitted at the time of Short Plat application. 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 percent of significant trees, and indicate how proposed building footprints would be sited to accommodate preservation of significant trees that would be Lund Short Plat, PRE12-068 Page 3 of 3 September 6, 2012 i:\rtimmons\preapps\12-068 (r-8 shpl lot width ).doc retained. If the trees cannot be retained, they may be replaced with minimum 2 inch caliper trees at a ratio of six to one. Critical Areas: There appear to be no critical areas on site however the site contains sensitive slopes and the applicant would be required to provide a Geotechnical Report at the time of short plat application. It is the applicant’s responsibility to ascertain whether additional critical areas are present on the site. If so, the proposal would need to be revised accordingly. Environmental Review Subdivision of land into nine or fewer lots or tracts is exempt from Washington State Environmental Policy Act (SEPA) review, unless critical areas are known to be on or near the site. The proposal would be exempt from Environmental Review per WAC 197- 11-800. Permit Requirements: The proposed subdivision would require Administrative Short Plat Approval and an Administrative Lot Width Variance. All land use permits would be processed within an estimated time frame of 6-8 weeks. The Short Plat Review application fee is $1,400 and the Variance application fee is $1,200 if the decide to proceed. A 3% technology fee would also be assessed at the time of land use application. Detailed information regarding the land use application submittal is provided in the attached handouts. Fees: In addition to the applicable building and construction fees, the following mitigation fees would be required prior to the recording of the plat. Impact fees, which would replace mitigation fees, may be adopted prior to construction. Those fees are to be determined. The following are current fees: A Fire Mitigation fee of $488.00 per new single family residence. A Transportation Mitigation Fee based on $75.00 per each new average daily trip attributable to the project; and A School District Impact Fee based on $6,392 per new single family residence. A Parks fee is not applicable for short plats but could be required in the future. A handout listing all of the City’s Development related fees in attached for your review. Expiration: The preliminary short plat approval is valid for two years with a possible one-year extension.
