Sample calculations
| ||
100 acres:
| ||
60 acres nonconstrained
| ||
10 acres wetland
| ||
10 acres at 25% grade
| ||
10 acres at 15% to 25% grade
| ||
10 acres at seasonal high-water table
| ||
60 acres x 1.0
|
= 60
| |
10 acres x 0.0
|
= 00
| |
10 acres x 0.2
|
= 2
| |
10 acres x 0.33
|
= 3.3
| |
10 acres x 0.33
|
= 3.3
| |
Total result
|
= 68.6 acres
| |
1-acre zone, 68 lots

NOTE: Each individual shall meet the minimum area requirements
for the zone after the constraints are factored in.
