Prime Hook National Wildlife Refuge Restoration

After being severely damaged by a series of storms, including Hurricane Sandy, the Prime Hook National Wildlife Refuge—a protected and critical sanctuary for migratory birds—required restoration and mitigation from the impacts of rising sea levels. The refuge and its adjacent water bodies are a key stopover site for migratory birds moving through the region and western Delaware Bay. It is also home to many threatened and endangered species. Atkins provided restoration and mitigation to the refuge and helped return it to its original state as a salt/brackish marsh after the habitat had been severely damaged by a series of storms. In addition to restoring habitat, the broader goal is to restore natural water flow, repair breaks in the existing dunes and create a marsh and beach more resilient in coastal storms. The Prime Hook tidal marsh restoration project has been the largest of its kind ever on the east coast of the United States. Over 15-months, construction included: a dune, beach, and back-barrier beach platform along nearly 8,000 feet of shoreline, restoration of 9-foot dune with a 100- to 600-foot-wide back barrier platform extending into the marsh, plantings and 10,000 feet of fencing have been installed to stabilize the area, dredging of more than 25 miles of tidal channels to restore flow, removal of several man-made water-control structures. All of which was done to revert the area back to a saltwater marsh with some areas of fresher or brackish wetlands. For more information, visit:
