Home

Commis.~ion will be reviewing the Comprehensive Plan Amendment and Rezoning request along with a preliminary plat and site plan for the development of the outlont at their regular meeting in June. 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 units are Sodium 'Street, 153rd Lane, Radium Street, and Tungsten Street. Staff is recommending that the proposed private street along the southwestern portion of the plat serve the development as a public 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 Man.agement Organization (WMO) and MPCA. A traffic generation analysis was performed by James Johnson PE. The study states that for the intersections of.Alp/ne 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. As mentioned in the City Staff Review Letter, the sanitary sewer trunk line will need to be extended to and through the development. The sewer and water trunk expenditures significantly exceed the revenues associate with this development. The Public Works Committee will be discussing this topic prior to the Planning Commission meeting on May 20th, staff will provide a verbal update. 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 density transitioning plan submitted is deficient in number of plantings and does not provide for a diversity of plantings. The plan will need to be revised to comply Mth City Code requirements. The Tree Preservation plan submitted does not provide information pertaining to the number of trees to be preserved, the species being preserved, and their sizes. Prior to the preliminary plat proCeeding to the City Council a revised and more detailed tree preservation plan will be required to be submitted. 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 $338,148 and land dedication of .5 acres to be utilized for public park purposes.
