Alpine Woods Preliminary Plat Review Revised: April 23, 2004 2of4 additional landscaping will be required for Lots 1, 2, 3, and 4 of Block 1 as well as Lots 2 and 3 of Block 2. iV[ore landscaping comments are located in the next section. Tree Preservation and Planting Plan: The City Council has adopted a Tree Preservation Ordinance that applies to your proposed plat. A tree preservation plan, dated March 31, 2004, was submitted to the City. The plan shows a total of 1,792 trees throughout the site and indicates that 1,195 of these trees will be preserved (597 trees will be removed to facilitate construction). Predominate species on this site include: Poplar, Ash, Oak, Elm, and Cedar and sizeg range from four (4) inches to almost forty (40) inches in diameter. City Code requires a minimum of two (2) trees per lot be installed in new, single-family residential lots. Trees should be installed near the front property lines. This minimum standard will apply to the following lots: Lots 1-5, Block 1, Lots 1-2, Block 2, Lots 1-2, Block 3, Lots 1 and 10, Block 4, and Lot I, Block 5. On many of the lots being created, a majority of the trees located in the "front" yards are being removed. However, again on most of the newly created lots, a number of existing trees will be preserved in the "back" yards. Therefore, on these lots, only one (1) tree shall be required to be planted in the front yard area near the front property line. These lots are. as follows: Lots 6-12, Block 1 and Lots 3 and 6-9 of Block 4. Lots 2, 4, and 5, Block 4, each of which has an existing home that is remaining, have sufficient tree coverage. No additional plantings are required on these three lots. Wetlands: A substantial portion of the property is wetland. A wetland delineation report has been submitted and verified. This development proposes no wetland filling. A permit from the Lower Rum River Water Management Organization is required and has been obtained for this development. Drainage: A drainage and grading plan-has been prepared by Mark. Kretchmer PE of Passe Engineering. This plan proposes to construct two ponds located on the north and south ends of the development. All street surfaces, and the future residential structures on the east side of Vanadium Street will drain to these ponds prior to overflowing into DNR protected wetland 734W. A review of this grading and drainage plan has been made and the following Comments are offered: I. Four existing residences are proposed to remain within the new subdivision. Existing low floor and at grade elevations need to be added for these structures to the grading plan. The plan must also illustrate how these existing residences will be connected to the new street system. 2. The overland drainage across Lot 6 Block 4 is flatter than 1%. The elevation of the house pad or the grading plan should be modified to correct this deficiency. Streets: The street system for this development has been detailed on a three-sheet set of plans.
