Case #5: Request for Property to be Rezoned from R-1 Single Family to R-2 Medium Density Residential; Case of Oak Creek Builders Case #6: Request for Preliminary Plat Review of Alpine Acres 2na Addition; Case of Oak Creek Builders Case #7: Request for Site Plan Review of Alpine Acres 2nd Addition; Case of Oak Creek Builders Presentation Associate Planner Wald advised that the subject property is approximately 42.4 acres in size and the applicant is proposing to develop a total of 202 townhomes and 1 existing single-family homestead for a total of 203 housing units. The property is zoned R-2 Medium Density Residential with the exception of the outlot in the southwestern portion of the plat along Alpine Drive, which is zoned R-1 Single Family. She stated the R-2 Zoning District allows for townhome developments up to 7 units per net acre. She explained that the preliminary plat is showing a net density of 6.3 units per acre. The preliminary plat is providing for a combination of public and private streets through the development. The public spines that will service the townhome units are Sodium Street, 153rd Lane, Radium Street and Tungsten Street. She noted Staff is recommending that the proposed private street along the southwestern portion of the plat serve the development as a public street. She stated Staff met with the developer' and he is agreeable to dedicating the road as a public street and the preliminary plat has been revised accordingly. Associate Planner Wald further advised that a traffic generation analysis was performed and states that above acceptable levels of service will be maintained with the build-out of Alpine Acres subdivision. She noted the development is subject to density transitioning since it is located adjacent to four existing single-family homes along the southwestern plat boundary line, and the applicant is proposing to satisfy density transitioning through the landscape buffer option. She advised City Code requires a 25-foot wide buffer area along the common boundary line, which in this case is approximately 1,000 feet in length. She stated Staff has received a revised landscape plan, and while they have not had time to review it in depth, it appears to meet the requirements. She indicated the Tree Preservation plan submitted has not been reviewed. The Park and Recreation Commission reviewed the sketch plan at their April and May meetings, and are recommending park dedication requirements be satisfied through a cash payment of $330,876 and land dedication of .5 acres to be utilized for public park purposes. She indicated the development is providing for an 8-foot bituminous trail along Nowthen Boulevard, Alpine Drive and Sunfish Lake Boulevard. The preliminary plat is also showing a 5-foot sidewalk along all public streets in accordance with City Code requirements. Associate Planner Wald stated the preliminary plat meets the 40% open space and 10% identifiable open space requirement. She indicated City Staff recommends preliminary plat and site plan approval subject to compliance with the City Staff Review Letter dated May 16, 2003. Planning Commission/June 5, 2003 Page 6 of 23
