Hilton Head Island’s beaches are essential to both the local community and the economy.
To protect and preserve this vital resource, the Town has scheduled a beach restoration project for Summer 2025, funded primarily by tourism revenue through the local Beach Preservation Fee.
Hilton Head Beach Renourishment Project Overview
The 2025 beach renourishment will follow the successful restoration efforts of 1990, 1997, 2006, and 2016. The project is set to place approximately 2.2 million cubic yards of beach-compatible sand along 46,500 feet of shoreline, stretching from the Atlantic Ocean to Port Royal Sound. The sand will be sourced from up to four offshore borrow sites.
This renourishment is part of the Town’s ongoing beach management program, which plans restorations every 8 to 10 years based on weather patterns and beach conditions. Notably, Pine Island in Hilton Head Plantation will be included in the 2025 project.
Sand Placement Areas
Sand will be placed across five key sections of the Island:
- South Beach / South Island: 10,230 feet of shoreline. 750,000 cubic yards of sand.
- Central Island: 28,860 feet of shoreline. 700,000 cubic yards of sand.
- The Heel (northeast point): 5,280 feet of shoreline. 500,000 cubic yards of sand.
- Fish Haul Creek: 2,130 feet of shoreline along Port Royal Sound. 50,000 cubic yards of sand.
- Pine Island Shoreline between Dolphin Head and Pine Island: 180,000 cubic yards of sand. Addition of six rock breakwaters for enhanced protection.
Construction Process
The sand for the project will be excavated by hydraulic dredge from offshore shoals, transported via pipelines, and distributed along the designated areas. Here’s how the process will unfold:
- Pipeline Delivery
Up to 50,000 feet of pipeline will be transported to the island, either by truck or floating rafts, and stored in stacks along the shoreline until construction begins.
- Sand Placement
A mixture of sand and seawater will be pumped through the pipeline onto the beach. The seawater will flow back into the ocean while the sand settles into place.
- Shaping the Beach
Bulldozers and other heavy machinery will shape the sand to meet the specified design standards.
- Progression and Beach Access
- Construction will move along the shoreline at a pace of 200 to 300 feet per day.
- Areas under active work (about 1,000 feet) will be temporarily closed to pedestrian access. These sections are reopened as soon as they are rough-graded.
The entire operation is expected to last approximately six months, running continuously 24/7.
Hilton Head Beach Renourishment Impacts on Residents and Visitors
While the project brings long-term benefits, there may be minor inconveniences during the construction phase:
- Noise
Construction noise will mainly come from bulldozers and other equipment shaping the sand.
- Temporary Closures
Individual sections of beachfront properties will experience closures for about 3–4 days as the project progresses.
- Minimal Disruption
Nearby residents or vacation renters might notice some short-term inconveniences, but efforts will be made to minimize disruptions and reopen areas quickly.
Long-Term Benefits
This renourishment project is critical for maintaining the health and beauty of Hilton Head Island’s beaches. It helps:
- Protect the Environment
Strengthen the shoreline against erosion and support coastal ecosystems.
- Boost the Economy
Preserve the island’s appeal as a destination for tourists, which in turn supports local businesses.
- Enhance Quality of Life
Offer clean, wide beaches for residents and visitors to enjoy year-round.
