On Kiawah Island, keeping an existing river or lagoon-edge bulkhead in good repair is far easier than getting a new wall approved, a point South Carolina's Supreme Court made in a Kiawah case.

Kiawah's river side has a legal history that every waterfront owner here should know. In 2014 the South Carolina Supreme Court reversed approval of a 2,783-foot bulkhead and revetment along the Kiawah River at Captain Sams Spit. The court said the state's rules require an applicant to prove there is no feasible alternative, including doing nothing and letting nature run its course. In 2026, a settlement placed the spit under a conservation easement, with the Town of Kiawah Island taking the Beachwalker Park parcel. The lesson for owners is plain. Look after the wall you have.
Our Charleston seawall repair team handles Kiawah projects from first inspection through state paperwork. Kiawah shares the Captain Sams Inlet area with Seabrook Island, whose older ocean-facing wall has its own long repair history. Across the Stono River Inlet, Folly Beach has a special exemption that Kiawah does not. To the southwest, Edisto Beach faces the same rules on new oceanfront walls.
A tide over five and a half feet. NOAA's Kiawah Bridge gauge on the Kiawah River records a mean range of 5.59 feet. That much water rising and falling against a wall works fine fill out through any gap.
A shoreline that moves. The Coastal Conservation League describes Captain Sams Spit as eroding and accreting regularly. Inlets and channels near the island shift, and a wall that once sat behind a sandbar can end up facing current.
Pluff mud. The marsh edge along the river is soft, fine sediment mixed with decaying cordgrass. It holds little, so a small void behind a wall can grow quickly.
Water that keeps rising. NOAA's Charleston Harbor record shows relative sea level up about 1.4 inches per decade since 1901.
It is hard. Regulation 30-12 allows a bulkhead or revetment only where it follows the critical area line. It is not allowed where marsh already protects the bank, or where it would hurt public access or neighbors, unless upland is being lost to tidal erosion. The Supreme Court's Captain Sams decision made clear the applicant carries the burden. The state also encourages living shorelines in estuaries as an alternative to hard walls.
On the Atlantic side, the Beachfront Management Act bars any new seawall or revetment on the active beach. Grandfathered structures may be maintained but not enlarged or strengthened.
Repairing what's there is the practical route. Where the wall is still standing true, polyurethane injection fills hollows and closes leaking seams from behind, through small holes in the cap. Landscaping and walkways stay in place. Cracked caps, rotted boards, and failed hardware get bulkhead repair from our Charleston crew. If a wall is rotating toward the water, seawall reinforcement in the Charleston area stops it with anchors.

It addressed a new 2,783-foot structure. Ordinary maintenance of an existing wall is a different question, though SCDES still decides whether a permit is needed.
The state encourages living shorelines in estuaries. Whether one fits depends on your bank, the creek width, and the wave energy.
With a mean range near 5.6 feet and soft marsh soil, a small leak can become a visible hole within a season. Catch it early.
Yes. Foam injection is quiet and needs little equipment, so we can phase work around tee times or events. ---
