Do you believe natural materials are an effective way to protect local shorelines from erosion?

Volunteers and The Nature Conservancy are finalizing a 2,000-foot living shoreline near the Marine Corps Air Station Beaufort in South Carolina. The project, which began in 2024, utilizes oyster castles to combat significant erosion along the Broad River.

Why it matters

This project demonstrates the use of natural and engineered materials to stabilize coastal areas against strong wave action. By creating a reef that facilitates biological growth, the effort aims to secure vulnerable land around the local base and housing complex.

The structure consists of oyster castles—modular units made of shell, concrete, and limestone—spanning 2,000 feet. This configuration replaces traditional hardening methods with materials capable of withstanding the wave energy in the Broad River.

The players

The Nature Conservancy

A global environmental nonprofit focused on conservation science and the implementation of nature-based solutions for climate resilience.

South Carolina Department of Natural Resources

The state agency responsible for the management and protection of South Carolina's natural resources, including coastal habitat restoration.

The details

The project functions by creating a substrate for oyster larvae, which attach to the shell-filled bags and oyster castles to develop a permanent reef. As the reef matures, it disrupts wave energy, which allows sediment to accumulate behind the structure and supports the growth of native marsh grass. Volunteers facilitate this construction by moving heavy castle components into place through a human chain across the shoreline.

2001: The South Carolina Department of Natural Resources began using oyster shells for shoreline construction.
2021: The state legislature passed living shoreline permitting rules.
2024: Construction on the Beaufort living shoreline project began.
October 24, 2026: The final volunteer event is scheduled to complete the shoreline.

The Tech Race

This project aligns with the state's 2021 living shoreline permitting rules, which codified a move toward nature-based erosion control. It follows 25 years of experimentation by the South Carolina Department of Natural Resources with oyster-based reef construction.

Residents near the Laurel Bay housing complex will see the stabilization of the nearby coastline as the 2,000-foot reef becomes fully operational. The structure effectively acts as a natural barrier to mitigate erosion caused by wave action in the Broad River.

The takeaway

The project highlights how nature-based engineering can address coastal instability near sensitive infrastructure. Residents can monitor the long-term effectiveness of the reef as the marsh grass and oyster populations continue to develop following the October 24 completion date.
