So, the short answer is, it's complicated. Without being at all political, there are potentially like 5 government agencies that could be involved; and just cause 1 doesn't regulate at say a state level, it doesn't mean one doesn't at the county level. You have FDEP/Water Management District; potentially ACE; County building department; County public works department; possibly FDOT (only if the property touches their ROW or drainage Easements).
