Riprap is sloped rock placed at the foot of a seawall or shoreline to take the force of waves. In Key West, placing it means working with state, federal, and marine sanctuary rules, because the rock goes into protected water.

We haven't found a Key West rule that requires riprap at the base of every seawall, the way some Florida cities do. The more important question here is whether it's allowed where you want it, and on what terms.
Riprap goes waterward of the wall, into state waters that lie inside the Florida Keys National Marine Sanctuary. That means:
We check the bottom in front of your wall before we design anything.
When waves hit a vertical wall, they bounce back down and dig at the base. That scour undermines the toe, and a wall that loses its toe starts to lean. A rock apron:
Irma showed how much force the water can bring. In the lower Keys, the Hurricane Center measured 5 to 8 feet of water above ground between Cudjoe Key and Bahia Honda Key. Walls with an armored toe have a better chance of riding out a surge like that.
Residential installs usually take several days once permits are in hand. Work from the water keeps heavy equipment off your yard where access allows.
Riprap installation in Key West typically costs $125–$350 per linear foot. A standard 75-foot residential installation runs $10,000–$25,000, fully installed and permitted. Rock size, water access and survey needs affect the final number.
Often it should. If your wall is being replaced or reinforced, adding toe rock at the same time means one mobilization and one round of permits. See bulkhead replacement in Key West or seawall reinforcement in Key West. If you already have a sloped rock shoreline rather than a vertical wall, see revetment maintenance in Key West. We also install riprap in Miami, and our Key West seawall repair page lists the rest of our local services.
It can, but if the work could affect corals, you'll need NOAA authorization along with state and federal permits. A bottom survey is part of that.
We survey first and keep the footprint tight. The permitting agencies review impacts to bottom habitat before approving the work.
That depends on water depth and slope. We design it so boat access to your dock and lift stays workable.
Maybe not. On calm interior canals, scour is often mild. Open-water frontage and walls with a scoured toe benefit most.
