The Massachusetts Coastal Zone map (PDF, 3 MB) shows these regions, the coastal communities covered, and the coastal zone boundary. Story Map Tours of the Massachusetts Coast, which were created for the routine federal review of the Massachusetts coastal program in April 2021, provide an overview of the entire 1,500-mile coastline, along with a story map of each CZM region with some highlights of coastal habitats, state parks and sanctuaries, ports and harbors, recreational beaches and waterfront access, and more.
Communities outside the coastal zone boundary can also receive technical assistance and other support from either the regional office nearest them or CZM's Boston office. In addition, CZM provides grant funding to all communities within the Massachusetts coastal watershed for efforts to reduce pollution of coastal waters from overland runoff.
