The heart and soul of Hilton Head Island is the 12 miles of beautiful beach that visitors and residents enjoy year-round. The beach is also the mainstay of the Island's environment and economy, and is why thousands live here and millions more visit.
In order to preserve our beach, an infusion of sand is needed along some of the coast to ensure the sandy shoreline is wide enough for everyone — visitors and residents alike — to play and relax in the surf and sun.
What is beach Renourishment?
Renourishment replaces sand lost to natural erosion and maintains a wide beach to ensure the health of our shoreline.
Why is beach renourishment important?
A wider beach safeguards a natural environment for endangered sea turtles and sea birds, and provides extended storm protection for oceanfront homes, villas and businesses. It also allows beach-goers to spread out, ride bikes and bask in the sun.
Hilton Head Island is the second largest barrier island on the East Coast, and most beach erosion is a naturally occurring phenomenon. Geologically, the Island is a "transgressive" relic coastal barrier that has migrated landward over the last several centuries. Controlled by forces of the Port Royal and Calibogue Sound, beach sand moves from the center of the Island toward its ends. The daily ebb and flow of water continually shapes the shoreline.
What is the beach renourishment process?
How often is beach renourishment needed?
A beach renourishment is necessary every seven to 10 years, depending on weather conditions and storms.
What happens after a beach renourishment project is complete?
Beach renourishment is an ongoing process. There are more than 60 beach monitoring stations that we maintain to observe sand from recent beach renourishment projects. Aerial photos are taken annually to monitor how the coastline changes.
