Dredge awaits action

USACE staff and contractors visit a material placement area along the Atlantic Intracoastal Waterway (AIWW), March 31, 2026. The dredge “Ahtna One” moved about 700,000 cubic yards of beach-quality sand from USACE’s routine maintenance of the AIWW to nourish the Isle of Palms coastal system. Unlike a traditional beach renourishment, which builds a wide, dry-sand beach, this project placed sand below the high-tide line at no additional cost the City of Isle of Palms. The AIWW operations and maintenance program largely paid for the project.
