Seawall and dock piling cleaning on the Miami River and the bay

We clean seawalls in Miami from the water. A diver takes the barnacles, oysters and algae off the wall and off the pilings under the dock. With the growth off, the diver looks at the surface for damage or erosion.

Some Miami seawalls come with paperwork. A City of Miami Building Department bulletin covers private walls whose owners were cited by a regulator, or must file a FEMA-required maintenance plan. Those owners hire an engineer, and the engineer's evaluation covers the wall above and below water. If growth covers the part below the waterline, we can take it off before the engineer's visit.

Ask about piling wrapping if the dock needs it. When you call, tell us the length of the wall, the piling count and whether you are on the river or the bay.

  • Miami's rule for cited private seawalls is Building Bulletin 2022-001.
  • That bulletin calls for an engineer's visual evaluation above and below water.
  • Miami says most of its tidal backflow valves are on the coastline and the Miami River.

Local notes for Miami

Miami's bulletin for private seawalls

City of Miami Building Bulletin 2022-001 sets the minimum for an operations and maintenance plan on a private seawall. It applies to owners cited by any regulatory body, and to owners FEMA requires to submit such a plan. The owner hires and pays an engineer, who must do at least a visual evaluation above and below water. If that is you, we can clean the wall ahead of the engineer's visit.

What the engineer signs before the permit closes

Under the same bulletin, the engineer documents and photographs the finished maintenance or repair and writes a report. The engineer then signs off that the wall gives the required level of flood protection. The bulletin calls that a prerequisite to finalizing the permit. Cleaning is not one of those papers; it is how the wall gets seen.

Tidal backflow valves on the river and the coast

The City of Miami says it is installing backflow valves citywide to deal with sea level rise and flooding. Most of the tidal valves are already in along the coastline and the Miami River, the City says. If an outfall or a valve sits in your stretch of wall, tell us where it is before the diver gets in.

Seawall & Dock Cleaning questions in Miami

Does the City of Miami require an engineer to inspect my seawall?

Yes, if a regulatory body has cited the wall or FEMA requires a maintenance plan for it. City of Miami Building Bulletin 2022-001 covers those private seawall owners. They must hire an engineer, who does at least a visual evaluation above and below water. The bulletin is written for those two cases.

Who signs off on a seawall repair under Miami's bulletin?

The owner's engineer signs off. Under City of Miami Building Bulletin 2022-001, the engineer documents and photographs the finished work and writes a post-repair report. The engineer then confirms the wall gives the required flood protection. The bulletin makes that a prerequisite to finalizing the permit. If the wall needs cleaning before the engineer's visit, that part is ours.

Do you clean dock pilings too?

Yes. We clean dock pilings along with the seawall in Miami, and we wrap pilings as well. That covers docks on the Miami River and on Biscayne Bay. If an engineer is evaluating the wall under the City's bulletin, ask whether the pilings should be cleaned for that visit too.

What do I tell you when I call about a seawall in Miami?

Tell us the length of the wall, the number of pilings and whether the dock is on the Miami River or Biscayne Bay. The City says most of its tidal backflow valves are along the coastline and the river, so mention any outfall or valve in your wall. If an engineer is coming, give us the date.

Is 6 Feet Under licensed and insured?

Yes. The crew that cleans your Miami seawall is licensed and insured. We are based in Fort Lauderdale and work down the coast to Miami, on the Miami River, on Biscayne Bay and near Government Cut. If your engineer or the Building Department is involved, tell us when you call.
