A living shoreline is a non-structural approach to maintaining shorelines by treating the area between land and water in a natural way. Instead of ending abruptly at the water’s edge like a common bulkhead, it creates a gradual transition between the bank and the water with slopes, vegetation, and low rock sills that slow wave energy and create habitat for fish, crabs, and other animals living along this transitional area. Native trees planted in the upland buffer provide shoreline stabilization and erosion control, while grasses and shrubs along the bank face add further erosion control and some habitat. In the tidal marsh and beach area, wetland plants provide habitat for nesting terrapins, horseshoe crabs, and other species, and this area is flooded during high tide. Rock sills add stabilization against wave energy. At Centreville Wharf, the shoreline was shown before October 2010 and during restoration in April 2011. The site’s historic shoreline also included a 20th century factory building of the Valliant Fertilizer Company, the second generation of the original that stood there at the beginning of the 1900s, and before that the Capt. Ozman shipping wharf and the Capt. Clash warehouses, which stood there from the mid-1800s.
