Summary

Gulfport requires a floodplain development permit before any grading, construction, or utility work begins inside a mapped flood hazard area. City Code Sec. 10.5-4.01 routes applications through the floodplain administrator, tied to FEMA's flood insurance rate maps for Pinellas County.

Any owner or owner's authorized agent (hereinafter "applicant") who intends to undertake any development activity within the scope of this chapter, including buildings, structures and facilities exempt from the Florida Building Code, which is wholly within or partially within any flood hazard area shall first make application to the floodplain administrator, and/or the building official if applicable, and shall obtain the required permit(s) and approval(s). No such permit or approval shall be issued until compliance with the requirements of this chapter and all other applicable codes and regulations has been satisfied.

Full Breakdown

5 of the Gulfport Code of Ordinances, the floodplain management ordinance, governs every parcel wholly or partly inside a flood hazard area, per Sec. 02. That scope reaches subdivision of land, grading, utility installation, construction or repair of buildings and structures exempt from the Florida Building Code, manufactured home placement, tank installation, recreational vehicle placement, and swimming pool installation. Sec. 03 sets the map basis: the Pinellas County flood insurance study dated August 24, 2021, and the accompanying FEMA flood insurance rate maps (FIRM), on file with the city's community development department.

Before starting any covered activity, Sec. 01 requires the owner or authorized agent to apply to the floodplain administrator, who under Sec. 01 is the city manager or a designee, and, where a building permit also applies, to coordinate with the building official. 5 and every other applicable code. A floodplain development permit lapses under Sec. 06 if work does not start within 180 days of issuance or is suspended for 180 days after starting; the floodplain administrator may grant extensions of up to 180 days each for justifiable cause, and may suspend or revoke a permit issued in error or on incomplete information under Sec.

07. Where field-surveyed topography shows ground below the closest applicable base flood elevation, Sec. 04 treats the parcel as flood hazard area subject to this chapter even where it is not delineated as a special flood hazard area on the FIRM.

Violations & Fines

Developing, filling, grading, or building in a flood hazard area without an issued floodplain development permit, or in conflict with an issued permit's conditions, is a violation of Sec. 10.5-8.01. A building or structure lacking required elevation documentation is presumed noncompliant until proof is filed. The floodplain administrator can require corrections, and continuing violations may draw enforcement under the general penalty in Sec. 1-6: up to a $500 fine or 60 days' imprisonment, each day a separate offense.

Frequently Asked Questions

Does Gulfport require a permit for filling or grading in a flood zone?

Yes. Sec. 10.5-4.01 requires an application to the floodplain administrator before any development activity, including filling, grading, utility installation, or accessory structure work, begins wholly or partly within a mapped flood hazard area. No permit issues until the applicant shows compliance with chapter 10.5 and every other applicable code, so plan review happens before work starts, not after.

Which flood maps does Gulfport use to define flood hazard areas?

The city relies on the Pinellas County flood insurance study dated August 24, 2021, and the accompanying FEMA flood insurance rate maps, adopted by reference under Sec. 10.5-2.03. Those studies and maps are kept on file at the city's community development department for public review, and later FEMA amendments automatically update the mapped flood hazard areas.

How long is a Gulfport floodplain development permit valid?

Sec. 10.5-4.06 voids the permit if the authorized work is not started within 180 days of issuance, or if it is suspended or abandoned for 180 days after starting. The floodplain administrator may approve one or more extensions of up to 180 days each, but only on a written request that demonstrates justifiable cause for the delay.
