No. 947]

      (1)   Developable acreage calculations.

         (a)   From the gross acreage of the site, subtract the following:

            [1]   Existing road  ultimate right-of-way .

            [2]   Noncontiguous land .

            [3]   Floodplain land: 100%.

            [4]   Wetlands: 100%.

            [5]   Ponds or lakes: 100%.

            [6]   Slopes from 15% to 25%: 50%.

            [7]   Slopes over 25%: 85%.

            [8]   Existing utility rights-of-way: 50%.

         (b)   The balance constitutes the total developable acreage .

         (c)   In the calculations above, the following shall apply:

            [1]   Land separated by roads or railroads or land where the connecting link is less than 50 feet wide is noncontiguous land .

            [2]   The calculated 100-year floodplain shall be used where available, otherwise alluvial soils shall be used.

            [4]   Utility corridors owned in fee simple by the utility shall not be counted towards the applicant’s land area.

      (2)   Density calculation. To determine the number of units permitted on a given site, multiply the developable acreage by 1.68 dwelling units per developable acre .
