Seawall with a large void where the concrete has eroded away, filled with repair cement

Lauderdale-By-The-Sea is a narrow barrier-island town best known for the living coral reef within 100 yards of its beach, which earned it the name Florida's Beach Diving Capital. The boats are on the other side, in the ocean-access canals of Bel Air and around Terra Mar Island, and with no marina in town they all live at private docks in salt water.

Where we work in Lauderdale-By-The-Sea

The whole town sits on a barrier island separated from the mainland by the Intracoastal, with a single drawbridge at Commercial Boulevard. Bel Air, about a mile north of the town center, has waterfront streets with no-fixed-bridge ocean access, and Terra Mar Island, just east of the Intracoastal, is a man-made island bordered by canals; both came into the town with the 2001 annexation. Town Hall is in ZIP 33308 and the Terra Mar area is 33062.

There is no marina and no public ramp inside the town, which is why every Lauderdale-By-The-Sea boat we clean is behind a house. The diver works from the dock and leaves; you don't need to be home. Anglin's Fishing Pier at the east end of Commercial Boulevard is the town's landmark on the ocean side, and there is no diving within 300 feet of it, which is fine, because our diving is all in the canals.

Why canal boats here foul fast

Bel Air and Terra Mar canals are salt water off the Intracoastal, and along the Broward Intracoastal the manatee rule keeps boats slow within 50 feet of shore. A boat that sits in a canal between runs out Hillsboro Inlet (the town is in the Hillsboro Inlet District) grows an algae band at the waterline and hard barnacles on the props and shafts, where bottom paint can't stick. Thirty days is the longest we let a canal boat go, and a hull without bottom paint gets cleaned every two weeks.

Docks and seawalls on a barrier island

Canal docks in Bel Air and on Terra Mar Island stand on pilings that oysters work on all year; we clean them without pickaxes or chisels and inspect them while they are bare. Broward County's seawall standard calls for tidal flood barriers of at least 5.0 feet NAVD88, and we have not found a town-specific ordinance beyond it. A seawall inspection here is $250 for a home and $350 for a multi-family property, cleaned first, with the lender-required documentation and a free in-person quote for any crack repair.

Lauderdale-By-The-Sea questions

There's no marina in town. Can you clean my boat at my dock on Terra Mar Island?

Yes, and private docks are nearly all of our work here. The diver works from your dock, cleans the hull, running gear and waterline every 30 days, and you get a dive report and photos afterwards without being home.

My Bel Air canal home has a boat lift and pilings. Do you clean those?

Yes, without abrasives and with no pickaxes or chisels. The lift's wheels and hardware get the barnacles cleared so they stop scraping the hull, and if the wooden pilings are covered in oysters the diver can wrap them in HDPE or fit Snap Jacket sleeves after the cleaning.

How often do you recommend cleaning in these canals?

Every 30 days for a painted hull that stays in the water, and every two weeks for a hull without bottom paint or a dock in nutrient-rich water. The photos from each visit will tell you which one your canal is.

What does a seawall inspection cost here?

$250 for a residential wall and $350 for a multi-family or commercial property, both with lender-required documentation. The growth is cleaned off first so the diver can actually see the concrete.
