Table 9. Administrative Waiver Criteria | ||
|---|---|---|
Relief Type | Required Findings | Allowed Relief |
Setbacks | ||
Increase the maximum setback or decrease the minimum setback due to existing site features such as trees, streams, wetlands, or topographical changes. | Existing site features would be negatively impacted if buildings follow the required setback; or The constraint of existing site features would not allow for construction of habitable spaces within buildings. | 20% max. |
Private Open Space | ||
The requirement for private open space may be waived in exchange for an equal or greater amount of shared open space. | One or more of the following hardship conditions must be met: 1. Due to site size, shape, topography, critical areas, easements, or other existing physical constraints, strict compliance with private open space standards would negatively impact existing site features; or 2. The applicant demonstrates, through site and financial analysis, that the requirement for private open space would result in disproportionate cost such that the project would be infeasible; or 3. Due to site topography, grade changes, or other physical conditions, providing private open space would conflict with ADA accessibility requirements or other code-mandated circulation and entry standards, making a functional unit layout or site design infeasible; or 4. Upper-level private open space (such as balconies) would be inconsistent with the established architectural character of surrounding residential development. In all cases, the shared open space provided in lieu of private open space shall be accessible to all residents, functionally usable, provide comparable amenity value, and be visibly and physically integrated into the overall site design. | Up to 100% private open space in exchange for an equal or greater amount of shared open space. |
