Purpose. The zoning districts established in this chapter (as set forth in the district regulations and on the zoning maps) are designed to guide the future use of the Village's land resources by encouraging the development and maintenance of desirable, residential, commercial, and manufacturing areas with appropriate groupings of compatible and related uses and thus to promote and to protect public health, safety and general welfare. As a necessary corollary, in order to carry out such purposes, nonconforming uses and structures which adversely affect the development of such areas must be subject to certain limitations.
