Barrier beaches are narrow, low-lying strips of beach and dunes that are roughly parallel to the coastline, and are separated from the mainland by a body of water or wetland. Hundreds of barrier beaches line the Massachusetts coastline. These landforms were created and are constantly changed by coastal processes, such as erosion, overwash during storms, dune movement, and inlet formation and migration

These dynamic systems are a tremendous resource providing recreation opportunities for beachgoers, fishermen, and off-road vehicle users; storm and flood protection for mainland areas; and habitat for plants and wildlife, including numerous rare and endangered species. In addition, many of these barrier beaches have been developed for recreational, residential, and commercial purposes. Managing barrier beaches to meet these competing uses is a complex task facing many local communities, organizations, and homeowners.

Along with providing direct technical assistance to those who are responsible for managing barrier beaches, CZM has two primary tools available to assist with barrier beach management:

• The Massachusetts Barrier Beach Inventory
• Guidelines for Barrier Beach Management in Massachusetts (PDF, 12.5 MB).
