Siesta Key is a barrier island, and the surveying follows from that. Lots sit close together along the Gulf and the island canals, areas like Siesta Village and Crescent Beach 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 Siesta 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 Siesta Key project clears design and permitting.

Common questions

Land surveying in Siesta Key: common questions

Do I need a survey to rebuild a home on Siesta Key?
Yes. Teardowns and rebuilds are common on Siesta Key, and a boundary survey confirms the tight lot lines and corners before design and permitting, especially on the narrow waterfront parcels near Siesta Village.
Do waterfront lots on Siesta Key need a survey for a seawall or dock?
Usually, yes. Seawall, dock, and frontage work along the Siesta 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 Siesta 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 Siesta Key.
Does ATHCA work on tight island lots on Siesta Key?
Yes. ATHCA regularly surveys the narrow, waterfront parcels on Siesta Key, handling the access and shoreline conditions and tying the work to the correct records and datum.
