Longboat Key is a barrier island, and the surveying follows from that. Lots sit close together along the Gulf and the island canals, areas like the Gulf-front condos and the bayside streets carry seawalls, docks, and direct water frontage, and parcels are tight enough that a few inches against a line or a seawall matters.

Because the lots are narrow and waterfront, the work concentrates on a few things. Boundary surveys matter on every teardown and rebuild, which are common on Longboat Key, and seawall, dock, and frontage questions come up constantly along the water. Coastal surveys locate the shoreline and structures, and hydrographic work measures the bottom where a dock or dredging project needs it.

We handle the island tight access and waterfront conditions directly, tying boundaries to the record and the shoreline and structures to the correct datum so a Longboat Key project clears design and permitting.

Common questions

Land surveying in Longboat Key: common questions

Do I need a survey to rebuild a home on Longboat Key?
Yes. Teardowns and rebuilds are common on Longboat Key, and a boundary survey confirms the tight lot lines and corners before design and permitting, especially on the narrow waterfront parcels near the Gulf-front condos.
Do waterfront lots on Longboat Key need a survey for a seawall or dock?
Usually, yes. Seawall, dock, and frontage work along the Longboat Key shoreline and canals depends on accurate boundaries and the water line, which a coastal survey establishes before permitting.
Can ATHCA measure the water depth for a dock or dredging on Longboat Key?
Yes. ATHCA provides hydrographic surveys that measure depths and bottom contours with sonar, tied to the same datum as the land survey, for docks and dredging around Longboat Key.
Does ATHCA work on tight island lots on Longboat Key?
Yes. ATHCA regularly surveys the narrow, waterfront parcels on Longboat Key, handling the access and shoreline conditions and tying the work to the correct records and datum.
