Sec. 14-11(4): Critical facilities. New critical facilities shall be, to the extent possible, located outside the limits of the special flood hazard area. Construction of new critical facilities may be permissible within the special flood hazard area if no feasible alternative site is available.

Full Breakdown
Sec. 14-1 defines "base flood elevation" as the elevation of the base flood, including wave height, measured against the vertical datum shown on the Flood Insurance Rate Map, and defines "lowest floor" as the lowest floor of the lowest enclosed area of a building, excluding unfinished or flood-resistant enclosures used only for parking, access or limited storage. Sec. 14-10(a) requires buildings, structures and facilities that fall outside the Florida Building Code's scope, and any substantial improvement or repair of substantial damage to them, to meet ASCE 24's flood load and flood-resistant construction standard.
Sec. 2 percent annual chance) flood elevation, whichever is higher, with access routes elevated as far as possible. Residential accessory structures in flood hazard areas cannot be used for habitation and must have no plumbing and only limited electrical service, while nonresidential accessory structures used solely for parking or storage get narrower size and elevation exceptions tied to whether they sit in a Zone A/AE or a coastal Zone V/VE area. Sec. 14-7(a)(2) requires a Florida-licensed surveyor to certify the lowest floor's elevation once it is placed and again at final inspection, before the floodplain administrator will sign off on further work.
Violations & Fines
Sec. 14-9 makes a building lacking the required lowest-floor elevation certification, or otherwise built out of compliance with Chapter 14's elevation and construction standards, a presumed violation. The floodplain administrator can issue a stop-work order or notice of violation, and conviction carries a fine of not more than $250 or imprisonment of not more than 180 days, or both, with each day of continuing noncompliance a separate offense.
