The following table is an example of that calculation:
| Adjustment Factor | Very Low | Low | Moderate | Above Moderate |
|---|---|---|---|---|
| RHNA | 300 | 200 | 165 | 465 |
| Entitled, Permitted, or Constructed Project Projects |
50 | 50 | 0 | 200 |
| Accessory Dwelling Unit Potential | 10 | 15 | 15 | 10 |
| Adequate Sites Alternative Preservation |
20 | 16 | ||
| Multifamily Residential R-3 (Vacant) |
75 | 50 | ||
| Mixed Use MU (Nonvacant) | 75 | 50 | 50 | |
| Multifamily Residential (Vacant) R-2 | 75 | |||
| Single-Family (Vacant) R-1 | 200 | |||
| Spring Valley Specific Plan | 150 | 250 | ||
| Total | 230 | 181 | 290 | 660 |
| Shortfall/Surplus | -70 | -19 | +125 | +195 |
While the jurisdiction has sufficient sites to accommodate its RHNA for moderate- and above moderate-income units, it has a shortfall of 89 units to accommodate its lower income need. The jurisdiction would be required to include a program in the housing element to accommodate that shortfall.
