A rock revetment in Beaufort needs an inspection every year and after every major storm, so rolled stones, a sinking toe, or exposed fabric get fixed before the bank behind them erodes.

A revetment is a sloped rock bank of armor stone over smaller stone and filter fabric. It soaks up wave and current energy instead of reflecting it. Over time, though, tides, wakes, and storms shift stones, and soft ground can let the toe settle.
SCDES regulates revetments on tidal water through its Bureau of Coastal Management and notes that normal maintenance and repair may not need a critical area permit. Expanding or reshaping a revetment is a different story. In unincorporated Beaufort County, larger work also goes through the county's bulkhead and riprap application.
| Timing | What to check |
|---|---|
| Spring | Full inspection; reset loose stone; fabric fixes |
| After a named storm | Displaced armor, toe damage, end washouts |
| After the highest tides of the year | Washouts along the top of the slope |
| Once a year at a very low tide | Toe settlement and transitions |
With a mean tide range near 7.4 feet at the Beaufort station, the toe is underwater for much of the day. We schedule visits for very low water so we can actually see it.
Storm history. Matthew brought 3 to 5 feet of inundation above ground in parts of the state and damaged many boats and marinas around Beaufort County (SCDNR). Water that high overtops most rock slopes and works on the upper stones, which are usually the smallest.
Soft footing. Many revetments here sit on or next to pluff mud. Over the years, the bottom row can settle, the slope steepens, and the upper stones start to roll. Watching the toe is the best early warning, and it's the part of the slope owners see least often.
Buffer rules. In unincorporated Beaufort County, re-planting is required after disturbance in the 50-foot river buffer, and sod isn't allowed (Beaufort County). Small, regular repairs usually disturb far less buffer than a full rebuild. That's another reason to fix a few stones each year instead of letting the slope unravel until it has to be rebuilt from the toe up.
Routine revetment maintenance in Beaufort typically runs $1,500–$5,000 per year for a standard 100-foot residential revetment. Major rehabilitation runs $150–$400 per linear foot. Regular care costs far less than a rebuild.
Adding rock to the base of a wall? See riprap installation in Beaufort. For year-round programs, see shoreline maintenance in Beaufort. Our Beaufort seawall repair page covers wall problems, and our hurricane prep guide covers pre-storm steps. We also maintain revetments in Hilton Head and Charleston.
Once a year, ideally in spring, and after any named storm or unusually high tide.
Routine maintenance and repair may not need a state critical area permit. Expanding or reshaping it usually does. We confirm first.
The toe is likely settling into soft mud, so the upper stones lose support. A toe rebuild on a firmer base fixes it.
Routine work is mostly done from the rock itself or from the water, which keeps buffer disturbance small.
