(A) Generally. In lieu of the yield plan method of § 154.266, developers may elect to use a yield formula to be used as the basis for determining the maximum number of dwelling units allowed prior to bonus calculations.
(B) Step 1 - Determine base site area. The first step of the yield formula involves calculating the site’s base site area, as follows:
1. Determine gross site area | acres |
2. Subtract ROW of existing streets (and ultimate ROW) | - acres |
3. Equals base site area | = acres |
(C) Step 2 - Determine net site area. The second step of the yield formula involves calculating the net site area, as follows:
1. Take base site area (from division (B) above) | acres |
2. Subtract regulated wetlands (> than 0.1 acres in area) and wetland buffers as required by the County Water Resource Ordinances or United States Army Corps of Engineers, whichever is more stringent: | - acres |
3. Equals buildable area | = acres |
4. Subtract 10% of buildable area for stormwater management | - acres |
5. Subtract 15% of buildable area for streets | - acres |
6. Equals net site area | = acres |
(D) Step 3 - determine number of dwelling units allowed. The third step of the yield formula involves a final calculation of the maximum number of dwelling units allowed on the site:
1. Take net site area (from division (C) above) | acres |
x UPA | |
3. Equals pre-bonus maximum number of dwelling units allowed | = units |
