A rock revetment on Lake Worth Lagoon should be inspected every year and after every major storm, so shifted stones and exposed fabric are fixed before the bank behind them erodes.

Seawall Repairs by Solid Foundations provides revetment maintenance in West Palm Beach, FL for lagoon-front homeowners, condo associations, and commercial owners. Typical projects include resetting armor stone on exposed lagoon slopes after storms, repairing torn fabric at the king-tide line, and rebuilding toes where revetments meet neighboring West Palm Beach seawalls.

A revetment is a sloped, rock-armored bank: big stones over smaller rock and filter fabric. It absorbs wave energy rather than bouncing it back like a vertical wall. It's tough, but storms, wake, and seasonal high water all shift stones a little. Left alone, those small moves open paths for the soil underneath to escape.
The ends go first, because water wraps around them. One missing armor stone may not look like much, but it exposes the smaller rock underneath to every wave, and once that layer moves the fabric and soil follow.
| When | What to check |
|---|---|
| Spring, before June | Full walk; loose stone; fabric condition |
| After any named storm | Displaced armor, scour, end washouts |
| After fall king tides | Washouts along the high-water band |
| Once a year | Slope profile, vegetation, transitions |
Mangroves that take root among the stones help hold the slope together. We work around them.
Less than the beach, usually, but not none. During Hurricane Irma in 2017, the National Weather Service recorded 1 to 2 feet of inundation at the beachfront from Fort Lauderdale north through the Palm Beaches (NWS Miami). Inside the lagoon, the larger threat is often wind-driven waves across open water, plus the extra water that comes in through the two inlets and down the flood-control canals. A few inches of added water depth lets waves reach stones higher on the slope. That's why we check the upper band as closely as the toe.
Rock shorelines are part of how the lagoon is recovering. Palm Beach County's restoration work includes projects like Snook Islands, which created about 11 acres of mangroves and 60 acres of seagrass (Palm Beach County ERM). A well-kept revetment gives oysters and fish surfaces to use and keeps sediment out of nearby seagrass. A neglected one sheds soil into the water every time it rains.
Routine revetment maintenance in West Palm Beach typically runs $1,500–$5,000 per year for a standard 100-foot residential revetment. Major rehabilitation runs $150–$400 per linear foot. Regular upkeep costs far less than rebuilding a neglected slope.

At least once a year, ideally before hurricane season, plus after any named storm.
Routine work within the existing footprint is typically simpler than expanding. Changes to the slope or footprint usually need permits. We confirm first.
Usually, yes. They help stabilize the slope, and we work around them.
Seasonal high water and waves concentrate there. It's where fabric gets exposed most often.
