General Information

The U.S. Army Corps of Engineers, Charleston District is currently working on a beach renourishment project to help provide protection against storm damage to people and property on Folly Beach. 1.5 million cubic yards of sand will be placed along the coast. 5.34 miles of beach will be renourished. A $30.7 million contract (with 15 percent cost-share from City of Folly Beach) was awarded to Great Lakes Dredge and Dock Company, LLC, of Oakbrook, Ill. The beach renourishment is being conducted as part of a 50 year agreement with the City of Folly Beach, and is the first periodic renourishment since 2005.

Clicking here or on the image above will take you to an interactive map that shows the progress of the renourishment of Folly Beach. You will see the blocks color coded showing which sections of the beach have been renourished and which section is currently underway. The blocks represent 500 foot sections of the beach. You can zoom in on the map to get closer views of the area and can also click on dots to see pictures of the area to help orient where on the beach you are looking at.

What Can You Expect?

During active beach renourishment construction, the majority of Folly Beach remains open and available for the public to enjoy. The construction contractor continuously moves along the beach during construction, usually 300 - 500 feet per day, barring breakdowns and weather/sea condition delays. That means that active construction that is fenced off will typically only be directly in front of any particular building for two or three days. Even then, the area fenced off is usually about 1,000 feet long, so it's easy to go around the active construction area. Walkovers, access ramps, etc. entering a fenced area will be blocked with fence or ribbon until the work has passed the area. Pipelines running along the beach outside of the fenced area can safely be crossed where the contractor places sand ramps over the pipes. The public should keep clear of these pipes except when crossing at a sand crossover. Even though there is an occasional minor inconvenience, it is for a major long-term benefit—to protect people and property from storm damage. Many people enjoy watching the construction activities and find it interesting and educational. The material is being borrowed off shore and the dredge may be visible from the eastern end of the beach. The contractor works 24 hours a day. There might be some construction noise at night related to heavy equipment such as bulldozers and front end loaders.

Vibration Monitoring

Great Lakes Dredge and Drydock Company, LLC, is prime contractor for project. Seismic Surveys, Inc., is the vibration monitoring subcontractor. Vibration is result of the movement of large equipment and the flow of water through pipes on the beach. SSI has conducted visual/photographic inspection of all beach front properties. They will monitor for vibration that is outside industry standards so action can be taken to reduce the impact to structures on the front beach.

Sand Fence and Planting

Once the renourishment is completed, relatively small crews construct sand fence along the beach. A crew of 10-15 specialists will set plants in and landward of the sand fence. The public is requested to not walk on/in the plant areas nor lean on or hang items such as towels, bags, etc. from the sand fence. These operations typically take 45-60 days and will only impact the area the crews are working in as they progress down the beach. There will be more information about this process once it is ready to begin.
