StormSmart Properties Fact Sheet 1: Artificial Dunes and Dune Nourishment

Find strategies to reduce coastal erosion and storm damage while minimizing impacts to the shoreline and neighboring properties from Massachusetts Office of Coastal Zone Management (CZM).

The coast is a very dynamic environment and coastal shorelines—especially beaches, dunes, and banks—change constantly in response to wind, waves, tides, and other factors such as seasonal variation, sea level rise, and human alterations to the shoreline system. Consequently, many coastal properties are at risk from storm damage, erosion, and flooding. Inappropriate shoreline stabilization methods can actually do more harm than good by exacerbating beach erosion, damaging neighboring properties, impacting marine habitats, and diminishing the capacity of beaches, dunes, and other natural landforms to protect inland areas from storm damage and flooding. StormSmart Properties—part of CZM's StormSmart Coasts Program—provides coastal property owners with important information on a range of shoreline stabilization techniques that can effectively reduce erosion and storm damage while minimizing impacts to shoreline systems. This information is intended to help property owners work with consultants and other design professionals to select the best option for their circumstances.

Fact Sheet 1: Artificial Dunes and Dune Nourishment

Sand, cobble, or other sediment (of appropriate size) is brought in from offsite to build a new dune (i.e., mound of sediment) or add to an existing dune to protect inland areas from erosion and flooding. Dune projects are appropriate for almost any area with sufficient space to maintain some dry beach at high tide.
