What is the Critical Area?
The Critical Area includes all land within 1,000 feet of Maryland’s tidal waters and tidal wetlands. It also includes the waters of the Chesapeake Bay, the Atlantic Coastal Bays, their tidal tributaries and the lands underneath these tidal areas. In Prince George’s County this includes areas along the Patuxent, the Potomac and the Anacostia Rivers. See PGATLAS.com for location of Chesapeake Bay Critical Areas.
