Preserving beyond 50 acres would be permissible, but the number
of lots possible is restricted by the amount of acreage available.

Note: The total number of buildable units that are feasible
on any parcel will vary depending on several factors, including but

or lakes, soil type, site topography, average lot size, total road
area, and general creativity of the designer. When calculations yield
numbers with decimals, the allowable number of units shall be rounded
