Folly Beach Undergoing Renourishment
Folly Beach is currently in the midst of a major beach renourishment project designed to combat erosion. While necessary for preserving the shoreline, the large-scale construction is causing significant disruptions for both local residents and tourists. Heavy machinery and closed-off sections of the beach are expected for the duration of the project.
This emergency renourishment is a direct response to damage from Hurricane Ian in 2022 and is entirely funded by the U.S. Army Corps of Engineers at a cost of $18 million. The project aims to place approximately 1.3 million cubic yards of sand, equivalent to about 130,000 dump trucks, along a five-mile stretch of the beach. Crews from contractor Gator Dredging are working 24/7 to complete the project by September 2024, before the peak of hurricane season. Rather than sourcing sand from offshore, a dredge in the Folly River pumps sand through a pipeline directly onto the beach, a method that saves both time and money. This also includes dredging the Folly River's federal navigation channel. Folly Beach's erosion problems are not new; they are largely a long-term consequence of jetties constructed at the entrance to Charleston Harbor in the 1890s. These jetties disrupted the natural flow of sand, leading to significant shoreline loss that began in the 1930s. The federal government began its involvement in protecting Folly Beach in 1993, which was the first major renourishment project. Since then, the island has received periodic and emergency sand placements, with notable projects in 2014 and 2018 following impacts from Hurricanes Matthew and Irma. Beyond creating a wider beach for recreation, the project's primary goals are to reduce storm risk to coastal infrastructure and restore critical habitat. A portion of the dredged material, about 40,000 cubic yards, is being used to restore Bird Key, an important habitat for local bird species. The U.S. Army Corps of Engineers and the City of Folly Beach are currently evaluating a new 50-year coastal storm risk management plan. This would replace the existing agreement, which is set to end in 2043, ensuring a long-term strategy for combating erosion and potential sea-level rise.
