A Story About NH’s Armor: What Does the State’s Tidal Shoreline Actually Look Like?


NHDES Coastal Program staff Hannah Blondin contemplates a berm on Route 1A in Rye.

This is the seventh story in the Shoreline Management Story Series, sponsored by the New Hampshire Coastal Program, the Great Bay National Estuarine Research Reserve, and the New Hampshire Coastal Adaptation Workgroup.

It was the summer of 2015, and Hannah Blondin was walking the shoreline. Find out what Hannah saw by jumping to our story map about the NH Inventory of Tidal Shoreline Protection Structures. CLICK HERE.

For a little more info:

A new spatial dataset documenting the type of New Hampshire’s tidal shoreline protection structures along the state’s tidal shoreline is now available for download and viewing on the N.H. Coastal Viewer and NH Granit. New Hampshire Department of Environmental Services staff identified and digitized the location of rip rap, walls, berms, and jetties along 326 miles of tidally-influenced shoreline using aerial photography and field verification. This effort found that 12 percent of the New Hampshire shoreline is hardened by some type of engineered armoring structure. Coastal professionals can now use this dataset in shoreline vulnerability assessments, which will aid efforts to identify candidate sites for living or hybrid shoreline protection approaches that may better protect public safety in the state and sustain natural, economic, and cultural resources.
