Beaches occupy only about two percent, or 75 miles, of Maine’s 5,300 miles of coastline. Hazards of living on a beach or in a sand dune system include hurricanes and nor’easters, erosion, storm surge, and flooding. Learn more about Maine’s beaches and dunes and determine if your beach property is eroding.
NOTE: Maine classifies all areas below the highest annual tide elevation, including rocky shores, sand beaches, mud flats, and salt marshes, as "Coastal Wetlands." In order to facilitate problem solving on this website, Coastal Wetland types have been grouped into three categories: Beaches & Dunes; Bluffs & Rocky Shores; and Coastal Wetlands.
