The second factor influencing the available buildable MUSA is the <br />difference between actual wetland areas delineated in accordance <br />with the 1991 Wetland Conservation Act and the wetland boundaries <br />depicted on the National Wetland Inventory (NWI) map. In <br />tabulating available MUSA, the Metropolitan Council credited <br />wetland areas identified in the NWI maps. The City, using nine <br />subdivision applications having wetland delineations completed, has <br />conducted a comparison between actual wetlands to the NWI wetlands. <br />Table H illustrates that the subdivisions being developed under the <br />Wetland Conservation Act are displayed an average of 50 percent <br />more wetland area than was defined by NWI maps for these plats. <br />Plat <br />TABLE H <br />COMPARISON OF ACTUAL WETLAND <br />DELINEATIONS TO NWI MAPS <br />Ratio of Actual <br />Actual Wetlands Acres <br />Gross Wetland NWI Based to NWI Based <br />Area Acres Wetland Acres Wetland Acres <br />Country Lake <br />Estates 33 2.49 .89 2.80 <br />Oaks of Lino 9 4.81 2.45 1.96 <br />Fox Trace 25 3.28 1.02 3.22 <br />Pine Ridge II 10 .99 1.11 .89 <br />Pine Ridge III 10 .69 1.02 .68 <br />Trappers Crossing 72 14.86 3.06 4.86 <br />Quail Ridge 38 15.80 14.38 1.10 <br />Behm's Century <br />Farm 93 40.64 23.26 1.75 <br />Clearwater Creek <br />Phase I and II <br />TOTAL <br />120 39.40 34.70 1.14 <br />410 122.96 81.89 1.50 <br />To date, the sites having the least environmental constraints and <br />the largest contiguous buildable areas have been selected for <br />subdivision and subsequent development.
