Foundations on land a hurricane created in 1848
Treasure Island exists as separate land because an unnamed 1848 hurricane cut the channel now called John's Pass through the barrier island, and the city itself wasn't incorporated until 1955, when Sunset Beach, Boca Ciega, Treasure Island, and Sunshine Beach merged into one municipality. Every foundation on the island sits on that same storm-formed barrier-island sand, regardless of which of the four original towns platted the block.
Settlement risk after Helene's 2024 surge
Hurricane Helene's 2024 storm surge, estimated at six to eight feet across Treasure Island, saturated soil around foundations citywide and forced a shutdown of potable water service, and saturated barrier-island sand can settle differently once it dries out than it did before the flood. A foundation evaluation on any pre-2024 structure here should account for that storm history, not just visible cracking.

Soil, water table, and permit basics for Treasure Island
Pinellas County's barrier and coastal soils sit on sand over porous limestone with a high water table in many areas, and a property's flood zone and elevation can affect both the diagnosis and the permitted repair approach.
Review county soil and flood-zone sources before scheduling an evaluation.
