preliminary plat and site plan of Alpine Acres 2nd Addition being revised to include a maximum development of four townhome units instead of the proposed six units on the subject outlot. The preliminary plat is showing a net density (exclusive of wetlands and major road right-of- way) of 6.3 units per acre. The proposed development complies with the R-2 maximum density restriction of 7 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 un/ts are Sodium Street, I53~d Lane, Radium Street, and Tungsten Street. A drainage and grading plan has been submitted and detailed comments are provided in the staff review letter attached to this case. The project is also subject to the review and permitting process of the Lower Rum River Watershed Management Organization (WMO) and MPCA. A traffic generation analysis was performed by James Johnson PE. The study states that for the intersections of Alpine Drive and County Road 57, Alpine Drive and CSAH #5, and Alpine Drive and Highway #47 above acceptable levels of service will be maintained with the build-out of Alpine Acres subdivision. The development is subject to density transitioning since it is located adjacent to four existing single-family homes along the southwestern plat boundary line. The applicant is proposing to satisfy density transitioning through the landscape buffer option. 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. The development complies with density transitioning requirements in regard to the number and type of plantings required to meet the landscape buffer option. A Tree Preservation plan has been submitted and details how many trees and what type of trees are going to be preserved. The tred' save areas appear to be located within desig-nated green space or open space areas, which provides for a nice amenity to the development. The Park and Recreation Commission reviewed the sketch plan at their April and May meetings. The Park Commission is recommending park dedication requirements be satisfied through a cash payment of $330,876 and land dedication of .5 acres to be utilized for future public park purposes. The development is providing for an 8-foot bituminous trail along Nowthen Blvd, Alpine Drive, and Sunfish Lake Blvd. The preliminary plat is also showing a 5-foot sidewalk along all public streets in accordance with City Code requirements. The preliminary plat is meeting the 40% open space and 10% identifiable open space requirement. The Planning Commission held a public hearing and reviewed the proposed preliminary plat at their June 5, 2003 meeting. During the public hearing a few residents from the Fox Knoll development, a res/denfial development located south of Alpine Drive, stated their opposition to the entire project area being zoned for R-2 Medium Density Residential and being developed with townhomes. -180-
