[Ord. No. 2357-12 § 25-28.9; amended 5-24-2022 by Ord. No. 2678-22]
When a lot contains rock formations, wetlands, wetland transition areas, state open waters, floodway, riparian zones, slopes exceeding 10%, land within 100 feet of a cliff face, land within 100 feet of a ridge line, depth to bedrock of less than four feet, or similar constraining conditions, the appropriate Board (Planning or Zoning), after adequate investigation, shall determine whether adequate contiguous area free of restraining conditions exist. In such an instance, it must be demonstrated that there is an adequate contiguous area on the lot which is free of constraining factors and which is sufficient to accommodate the proposed development, including, but not limited to, all access drives, parking areas, front, rear and side yards and the like, constructed in accordance with all the provisions of this section. The unconstrained area shall have a width as defined in § 25-4, lot width, but for a depth sufficient to build a structure, within the minimum bulk requirements.
