Flood zone can change what the repair is permitted to be
For structural work, the FEMA map is not paperwork — inside a mapped flood zone, the cost of improvement relative to the structure's value can trigger requirements that change the whole project. Clearwater Planning and Development administers that locally. On sandy peninsula soils the movement itself is usually settlement or erosion rather than clay behavior, which is a different diagnosis from most national guidance.

Establish zone and cause before committing to a scheme
Citywide mapping cannot establish your parcel's zone, your structure's valuation, or what is actually moving beneath it. Get the first two from the city and the third from an engineer with no stake in the repair being sold.
