Boat lift service and maintenance in Miami Beach

Who this is for

Every lift owner, and anyone whose lift has gone more than a year without a service.

Tide at Government Cut

NOAA's Miami Harbor Entrance gauge at Government Cut, beside South Beach, shows a 2.46 ft mean range and a 2.70 ft great diurnal range, with mean higher high water about 0.33 ft above NAVD 88 (1983 to 2001 epoch). A wall at 5.7 ft NAVD therefore stands roughly 5.4 ft above an average high tide, the margin the City wants for king tides and sea level rise.

The tide range decides how much of the cables and cradle sit in salt water, which drives the service schedule.[1]

Citations for overtopping

If tidal water flows over or through a wall, the City can cite the owner, and owners without a seawall can be cited too. After a citation there are 10 days to appeal, 60 days to show progress and 730 days to finish, with fines of $250 for a first offence and then $500 a day.

Service visits include checking that motors and switches sit above likely flood levels.[2]

Narrow island canals and the 25% rule

On the narrower Miami Beach canals, DERM's short form allows a dock, lift or davit to reach no more than 25% of the waterway width. DERM also uses a D-5 boundary to protect a neighbour's view and access, so it may ask for a letter of consent from the lot next door.

Regular service keeps an existing lift working, which avoids the permit a replacement would need.[3]

What makes Miami Beach different

The city has about 55 miles of seawall, of which only about 5 miles are publicly owned, so most of it is the responsibility of private owners. Its seawall ordinance dates from Resolution R2016-4009 in May 2016, was strengthened in January 2021 and amended again in July 2025.[2][5]

Groundwater and flooding

The city notes that groundwater rises through the porous bedrock under Miami Beach, so a seawall alone cannot stop flooding. A raised wall stops tidal overtopping; drainage and flood protection handle the rest.[6]
