§ 300-319 Determining site capacity.
[Amended 6-19-2006 by Ord. No. 103; 8-1-2024 by Ord. No. 24-104]
A.
Residential. The individual site capacity is determined by calculating the net buildable site area. For single-family, single-family cluster, or performance subdivisions, the number of dwelling units permitted is determined by multiplying the density factor with the net buildable site area. Calculations are as follows:
Table 300-319-A | ||||
|---|---|---|---|---|
1. | Take base site area | _____ acres | ||
2. | Multiply by district open space ratio | x | _____ acres | |
3. | Equals open space — calculation 1 | = | _____ acres | |
4. | Note area of lands consisting of floodplain, wetland, lake or pond; associated lands zoned for Resource Protection | _____ acres | ||
5. | Is the amount of land in floodplain, wetland, lake or pond, or associated lands zoned for Resource Protection (line 4) equal to or exceed the amount of open space — calculation 1 (line 3), Yes or No? | |||
6. | Open space adjustment factor: | |||
If the answer to Line 5 is Yes, then the adjustment factor is 0.50 (50%) | ||||
If the answer to Line 5 is No, then the adjustment factor is 1.00 | ||||
What is the open space adjustment factor? | _____ (either 0.5 or 1.0) | |||
7. | Take open space — calculation 1 from line 3 | _____ acres | ||
8. | Multiply by open space adjustment factor from line 6 | x | _____ | |
9. | Equals required minimum open space | = | _____ acres | |
10. | Take base site area | _____ acres | ||
11. | Subtract minimum required open space | _____ acres | ||
12. | Equals net buildable area | = | _____ acres | |
13. | Take net buildable area | _____ acres | ||
14. | Multiply by district maximum density factor | x | _____ | |
15. | Equals number of dwelling units (round down only) | = | _____ units | |
B.
Nonresidential. Maximum floor area is determined by calculating the net buildable site area. Developable floor area (square feet) is determined by multiplying the floor area factor with the net buildable site area. The maximum impervious surface allowed is determined by multiplying the impervious surface ratio with the net buildable site area.
Table 300-319-B | |||
|---|---|---|---|
Base site area equals net buildable site area | = | _____ acres | |
Take net buildable site area | _____ acres | ||
Multiply by floor area factor | x | _____ | |
Equals maximum floor area | = | _____ acres | |
Take net buildable site area | _____ acres | ||
Multiply by impervious surface ratio | x | _____ | |
Equals maximum impervious surface | = | _____ acres | |
§ 300-320 Residential performance subdivisions.
[Amended 8-1-2024 by Ord. No. 24-104]
Performance subdivisions may contain one or more housing types; for example, single-family house, duplex, and multifamily buildings. Such subdivisions shall contain the minimum amount of open space required by the performance standards.
