Harbor Deepening


Charleston Harbor has been a key economic driver for more than 300 years. With the deepest water in the region today, Charleston offers a maintained harbor of -45 feet (13.7 meters) of depth at mean low tide throughout the main shipping channel and -47 feet (14.3 m) in the entrance channel. A five to six foot tidal lift provides even deeper access for several hours during the day.

MSC VesselIn addition to having deep water now, the Port of Charleston is advancing a next-generation harbor deepening project. The U.S. Army Corps of Engineers completed the project's reconnaissance study in the summer of 2010 and determined that there is not only a federal interest in the further deepening of Charleston Harbor, but also that it was most likely the best value for scarce public dollars.

On Oct. 7 the U. S. Army Corps of Engineers (USACE) released a Draft Integrated Feasibility Report and Environmental Impact Statement for the Charleston Harbor Post-45 Project. The report recommends the harbor be deepened to 52 feet, and recognizes that this project is essential to our state’s economic future. There is a 45-day window for public comments through November 24, 2014.
