StormSmart Properties Fact Sheet 4: Bioengineering - Coir Rolls on Coastal Banks

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 4: Bioengineering/Coir Rolls on Coastal Banks

Coastal bioengineering projects use a combination of deep-rooted plants and erosion-control products made of natural, biodegradable materials, such as coir rolls. Coir rolls are long, cylindrical rolls of mesh packed with coir fibers (i.e., coconut husk fibers). They can be stitched together to provide a continuous physical barrier that helps reduce erosion of exposed sediments on a bank. Coir rolls can be used on both sheltered and some exposed sites where there is dry beach at high tide, but may require more frequent maintenance in exposed conditions.
