Description: The Coastal Boundary is a 1:24,000-scale, polygon feature-based layer of the legal mylar-based maps adopted by the Commissioner of the Department of Environmental Protection (DEP) showing the extent of lands and coastal waters as defined by Connecticut General Statute (C.G.S.) 22a-93(5)) within Connecticut's coastal area (defined by C.G.S. 22a-94(c)). The mylar maps were adopted on a town by town basis. This information does not replace the legal maps and may not be used for legal determinations. The data was compiled at 1:24,000 scale and is not updated.
Any regulated activity conducted within the coastal boundary by a municipal agency (i.e., plans of development, zoning regulations, municipal coastal programs and coastal site plan review must be conducted in a manner consistent with the requirements of the Connecticut Coastal Management Act (CMA; C.G.S. 22a-90 to 22a-113). As the Coastal Boundary is contained within the Coastal Area, all state and federal agency activities must be consistent with the requirements of the CMA.
