Certain natural conditions, historical conditions, capital improvements or development
pressures present opportunities or pose problems which involve a special public interest,
but do not coincide with traditional zoning district boundaries, although they apply
to specific geographic areas. An overlay zoning district can be useful in such situations.
An overlay zone is a mapped zone that imposes a set of requirements in addition to
those of the underlying zoning district. In an area where an overlay district is established,
the property is placed simultaneously in the two zones, and the land may be developed
or utilized only under the conditions and requirements of both zones. This division
consists of overlay zoning districts as required to serve the public health, safety
and general welfare.
