Each property proposed for development shall, at the time of rezoning, site plan approval or subdivision, submit a site capacity analysis based on the physical conditions, hazards and natural resources present on the site.
A. Purpose: There are areas where it is hazardous to life and property to construct a building, and these areas should be avoided. The destruction of some resources and certain development practices lead to ground and surface water pollution. Other development practices lead to air pollution. Natural systems are self-balancing, provided enough of the system is left in a functioning condition. This section ensures that the development will respect these resources; it prevents development from occurring in areas where it should not. In addition to health and safety concerns, resources provide habitat and help establish the character of Lake Villa. Their preservation enhances property values and the quality of life for residents and businesses.
B. Applicability: All development in all districts shall conduct a site capacity analysis except for the following:
1. Any lot of record as of April 14, 1988, proposed for residential use, which cannot be further subdivided or which is buildable after floodplains or wetlands are taken into account, but would not be buildable after other resource standards are applied.
2. Any lot of record as of April 14, 1988, proposed for a nonresidential use which is less than twenty thousand (20,000) square feet in area and is buildable after floodplains or wetlands are taken into account, but would not be buildable after other resource standards are applied.
3. Individual lots in subdivisions or land developments approved subject to the provisions of this title, since protection is achieved in the subdivision approval process. (Ord. 2004-01-01, 1-14-2004; amd. Ord. 2017-02-02, 2-8-2017)
