FEMA Flood Zone Lookup

FEMA assigns every parcel in the U.S. a flood-hazard designation on its Flood Insurance Rate Maps (FIRMs). Zones starting with A or V are high-risk Special Flood Hazard Areas where federally backed mortgages require NFIP flood insurance. Zone X indicates moderate-to-minimal risk, where insurance is optional but often recommended. Your specific zone determines insurance cost, build elevation, and permit requirements in Boca Raton, FL.

Summary

Any development, from grading to new construction, inside a mapped special flood hazard area in Boca Raton needs a permit before work starts. City Code Sec. 21-51 requires the applicant to apply to the floodplain administrator and the building official and obtain approval, and bars issuing that permit until the project satisfies Chapter 21's floodplain rules and every other applicable code.

Any 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 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

Chapter 21, Flood Damage Prevention and Floodplain Management, applies citywide to any development wholly or partially inside a special flood hazard area, a scope Sec. 21-5 defines broadly to include subdivision of land, filling and grading, utility installation, construction or demolition of buildings and structures, manufactured home placement, tank installation, recreational vehicle placement, and swimming pool installation. Sec. 21-51 makes the permit mandatory: anyone undertaking development in that scope, including structures otherwise exempt from the Florida Building Code, must apply to the floodplain administrator and, where applicable, the building official, and cannot get the permit until the requirements of Chapter 21 and all other applicable codes are satisfied.

The special flood hazard areas themselves are established by the Flood Insurance Study for Palm Beach County and Incorporated Areas dated December 20, 2024, and the accompanying FIRM maps, adopted by reference under Sec. 21-19 and kept on file at the development services department's code compliance division, 200 Northwest 2nd Avenue. Sec. 21-53 separately requires a floodplain development permit, even for structures the Florida Building Code exempts, such as railroads, farm buildings, temporary construction sheds, and Miccosukee or Seminole chickees, if they sit in a mapped flood hazard area.

A permit issued on incorrect or incomplete information can be suspended or revoked by the floodplain administrator under Sec. 21-57, and unpermitted development is subject to the floodplain administrator's inspection and enforcement authority under Sec. 21-37.

Violations & Fines

Developing in a special flood hazard area without the Sec. 21-51 permit, or on a permit obtained through incorrect or incomplete information, lets the floodplain administrator suspend or revoke approval under Sec. 21-57 and order the work stopped. Because Chapter 21 does not set its own fine schedule for this section, violations fall back on Sec. 1-16's citywide general penalty: up to a $500.00 fine, up to 60 days in jail, or both, with each day of the violation a separate offense.

Frequently Asked Questions

Do I need a city permit to develop in a Boca Raton flood zone?

Yes. Sec. 21-51 requires anyone developing land wholly or partly within a special flood hazard area, including grading, filling, pools, and structures otherwise exempt from the Florida Building Code, to first apply to the floodplain administrator and obtain approval. No permit issues until the project meets Chapter 21's floodplain rules and every other applicable city code.

How does the city decide which properties are in a flood hazard area?

Sec. 21-19 adopts the Flood Insurance Study for Palm Beach County and Incorporated Areas, dated December 20, 2024, along with its Flood Insurance Rate Maps, as the official basis for special flood hazard area boundaries. Copies are kept on file for public inspection at the development services department's code compliance division.

Can the city take back a floodplain permit already issued?

Yes. Sec. 21-57 authorizes the floodplain administrator to suspend or revoke a floodplain development permit that was issued in error based on incorrect, inaccurate, or incomplete information, or that violates Chapter 21 or any other city ordinance or regulation.
