Notes:
Overlay Zoning: This land use management technique consists of superimposing additional regulatory standards, specifying permitted uses that are otherwise restricted, or applying specific development criteria onto existing zoning provisions. Overlay zones are mapped districts that place special restrictions or specific development criteria without changing the base zoning. Overlay zones can also be created to protect wetlands, forests, historic sites, or even barrier islands and their surrounding resources. The advantage of overlay zones is that specific criteria can be applied to isolated areas and overlay districts are not necessarily restricted by the limits of the underlying base zoning. An overlay zone may take up only part of an underlying zone or may even encompass several underlying zones. Often, the utilization of an overlay zone is optional.
This is a map of a barrier island that would benefit from zoning measures to protect its resources.
