0183 approval STAFF REPORT City of Yelm Community Development Department   Case Number: SHS-04-0183-YL Applicant: Airborne Properties, LLC Agent: 2M Enterprises, LLC Request: Short Subdivision of 2.38 Acres into 9 Single Family Lots Recommendation: Approval with conditions Proposal The applicant proposes to subdivide 2.38 acres into 9 single family residential lots. Property Characteristics The property is located at the east end of 104th Avenue SE. It is currently vacant land. Notice of Application Notice of this application was mailed to state and local agencies and the owners of property within 300 feet of the project site on November 17, 2004. Concurrency Chapter 15.40 YMC requires the reviewing authority to determine that required urban infrastructure is available at the time of development. Concurrency with sewer infrastructure is achieved pursuant to Section 15.40.020 (B)(1) YMC when the project is within an area approved for sewer pursuant to the adopted sewer comprehensive plan for the city and improvements necessary to provide city standard facilities and services are present to meet the needs of the proposed development. Concurrency with water infrastructure is achieved pursuant to Section 15.40.020 (B)(2) YMC when the project is within an area approved for municipal water service pursuant to the adopted water comprehensive plan for the city and improvements necessary to provide city standard facilities and services are present. Concurrency with transportation infrastructure is achieved pursuant to Section 15.40.020 (5)(c) YMC when the project: Makes on-site and frontage improvements consistent with city standards and roads necessary to serve the proposed project consistent with safety and public interest; Makes such off-site facility improvements, not listed on the capital facilities plan, as are necessary to meet city standards for the safe movement of traffic and pedestrians attributable to the project; Makes a contribution to the facilities relating to capacity improvements identified in the adopted six-year traffic improvement program, in the form of a transportation facility charge. Concurrency with school infrastructure is achieved when the developer provides a letter from the local school district that the school facilities impacted by the proposed development are present, or are on an approved and funded plan, to assure that facilities will be available to meet the needs and impacts of the proposed development. State Environmental Policy Act This short subdivision is exempt from SEPA environmental review under Section 197-11-800(6)(a) WAC, however development of this parcel was included and reviewed as part of a series of exempt and nonexempt actions and is conditioned by the Mill Pond Estates Phase I Mitigated Determination of Nonsignificance, SEPA #8358 issued January 30, 2004. Lots Size and Setbacks The Yelm Zoning Code does not establish minimum or maximum lot sizes, although it does require standard yard setbacks of 15 feet from the front property line adjacent to local access road with a minimum 20 foot driveway approach, 5 feet from side property lines with a minimum of 12 feet between the two side yards, and 25 feet from the rear property line. The setback for a flanking yard is 15 feet from the property line. The lots within the proposed preliminary subdivision appear to contain sufficient area to meet setback and lot coverage requirements, if conditioned as recommended. Adjacent Land Uses and Zoning The property is adjacent to State Route 507 (Yelm Rainier Hwy) to the northwest, and a residential subdivision currently in construction to the east. To the west is the Hawks Landing residential subdivision, and to the south, single family residential homes. Open Space The Growth Management Act establishes a goal for open space and recreation that states “encourage the retention of open space and development of recreational opportunities, conserve fish and wildlife habitat, increase access to natural resource lands and water, and develop parks” [RCW 36.70A.020(9)]. Chapter 14.12 YMC provides guidelines for the retention and creation of open space within the City. This chapter requires a minimum of five percent of the gross area of a new subdivision be dedicated as usable open space. Appropriate uses of dedicated open space include: Environmental interpretation or education Parks, recreation lands, or athletic fields Footpaths or bicycle trails No more than five percent of any dedicated open spaces may be impermeable surfaces and open space must be sited so as to be suitable for its intended purpose and at least 75% of the open space must be assessable to either the general public or all residents of the associated development. The applicant proposes to apply the open space dedicated in Mill Pond Estates to qualify for the open space required for this phase. The open space in Phase I was a very large wetland pond and buffer area. This wetland was preserved in its natural state, and meets the requirement of environmental interpretation, and is more than enough land area to meet the open space requirements of phase I and phase II. To apply this area as open space for phase II, the applicant shall provide one homeowners agreement for both Phase I and Phase II. Schools New residential units create a demand for additional school services and facilities. The Yelm School District requests that the applicant enter into an agreement with the school district for the payment of mitigation fees based on the project’s impact. This request for a mitigation agreement between the developer and the school district became a mitigation measure of the Environmental Determination. Transportation and Site Access The City of Yelm Development Guidelines and the concurrency requirements of Chapter 15.24 YMC require all new subdivisions to improve street frontages to current City standards. Frontage improvements on 104th Avenue SE are currently being constructed as part of the Mill Pond Estates Phase I. The proposal does not include internal streets, with all lots having access from 104th Avenue SE. The completed project will increase traffic and impact the City’s transportation system. Chapter 15.40, Concurrency Management, requires all development to mitigate impacts to the City transportation system. A single family home generates 1.01 p.m. peak hour trips per unit. The Transportation Facility Charge per unit is $757.50 and payable at time of building permit issuance. Parking Chapter 17.72 YMC requires minimum parking ratio of two spaces per dwelling unit, which is typically met in subdivisions with a standard driveway. Water System The City’s Water Comprehensive Plan identifies the property as being within the water service area and the property is currently served by City water. The current fee to connect to the City water system is $1,500.00 per Equivalent Residential Unit (each ERU equals 900 cubic feet of water consumption per month). There is an existing watermain located on 104th Ave. SE. Connection to this watermain is subject to a latecomer’s agreement in the amount of $11,496.08. Payment of the latecomer fee is required prior to final plat approval. The proposed subdivision would be required to connect to the City's water system to serve fire hydrants and individual services. An irrigation meter may be installed for the purpose of irrigation. A backflow prevention device will be required for all landscape irrigation connections between the irrigation system and the water meter. This also includes any individual irrigation systems that may be located on any individual lot within the subdivision. The City of Yelm is dedicated to providing the best quality water possible to its consumers. Section 246-290-490, Washington Administrative Code, requires that the City take measures to ensure that contamination does not occur as a result of cross contamination. Sewer System The City’s Sewer Comprehensive Plan identifies the property as being within the sewer service area. The current fee to connect to the City sewer system is $5,417.00 per Equivalent Residential Unit (each ERU equals 900 cubic feet of water consumption per month). There is an existing sewermain located on 104th Ave. SE. Connection to this sewermain is subject to a latecomers agreement in the amount of $9.892.24. Payment of the latecomer fee is required prior to final plat approval. Stormwater Quality and Quantity Impervious surfaces create stormwater runoff which, when uncontrolled and untreated can create health, safety, and environmental hazards. The City of Yelm has adopted the 1992 Department of Ecology Stormwater Manual. The applicant has submitted a preliminary stormwater report which includes a conceptual design for the treatment and infiltration of the stormwater. The Community Development Department has reviewed this report and find that stormwater from the site can be managed appropriately through the conceptual plan. Civil plan review will include a final stormwater plan consistent with the preliminary plan. Stormwater facilities require continued maintenance to ensure they remain in proper working condition. Street Lighting Adequate street lighting is necessary to provide safety to pedestrians, vehicles, and homeowners. Street lighting is reviewed at the time of civil plan review in order to assure adequate lighting. Subdivision Name and Addressing The subdivision is being called Mill Pond Estates II. Addressing for the proposed residential lots will be assigned by the Community Development Department prior to application for final subdivision approval. Landscaping Landscaping and screening are necessary to provide screening between compatible and incompatible land uses, to safeguard privacy and to preserve the aesthetic assets of the City. Chapter 17.80 YMC requires all development to provide on site landscaping. The site is adjacent to properties that are compatibly zoned. Chapter 17.80 YMC requires that the perimeter of the site be landscaped with a Type II landscaping. In residential subdivisions the City allows fencing to meet the landscaping requirement for the perimeter of the site. Landscape requirements shall be installed and approved prior to application for final plat. Landscaping is required in open space and above ground stormwater facilities. Chapter 17.80 YMC requires that at time of civil plan review and approval the applicant provide the Community Development Department a detailed final landscape and irrigation plan for approval. Section 17.80.090 (F) YMC states that the owner/developer of any project requiring site plan review approval, subdivision approval, or short subdivision approval shall provide a performance assurance device in order to provide for maintenance of the required landscaping until the tenant or homeowners’ association becomes responsible for landscaping maintenance. The performance assurance device shall be 150 percent of the anticipated cost to maintain the landscaping for three years.
