Research notes

Applies to the six coastal counties (Bryan, Camden, Chatham, Glynn, Liberty, McIntosh) and any municipalities therein. Jurisdiction extends to all tidally influenced coastal marshlands. State permitting authority overlays local zoning — local zoning may permit a use, but a CMPC permit is independently required for marsh alteration. Often paired with the federal Coastal Zone Management Act (CZMA) consistency review and the federal §404 Clean Water Act wetlands permit.
