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 Orlando, FL.

Zone	What it means	NFIP required?
A	High-risk flood area; 1% annual chance flood, no detailed analysis.	Yes
AE	High-risk; same as A but with established Base Flood Elevations.	Yes
AH	High-risk shallow flooding (1-3 ft), usually ponding.	Yes
AO	High-risk shallow flooding (1-3 ft) with sheet flow on sloping terrain.	Yes
V	High-risk coastal zone subject to wave action (no BFE).	Yes
VE	High-risk coastal zone with wave action and established BFEs.	Yes

Summary

Orlando's Floodplain Regulations, City Code § 63.220, govern nearly every kind of development touching a flood hazard area: subdividing land, grading, building or altering structures exempt from the Florida Building Code, placing manufactured homes and tanks, siting recreational vehicles, and installing swimming pools. A handful of provisions reach even further, applying citywide, including to properties outside any mapped special flood hazard area.

(a)Title. These regulations, with Chapter 65 Part 6D and Part 6E shall be known as the Floodplain Regulations of the City of Orlando, hereinafter referred to as "the Floodplain Regulations."(b)Scope. The provisions of this Part shall apply to all development that is wholly within or partially within any flood hazard area, including but not limited to the subdivision of land; filling, grading, and other site improvements and utility installations; construction, alteration, remodeling, enlargement, improvement, replacement, repair, relocation or demolition of buildings, structures, and facilities that are exempt from the Florida Building Code; placement, installation, or replacement of manufactured homes and manufactured buildings; installation or replacement of tanks; placement of recreational vehicles; installation of swimming pools; and any other development. Where stated explicitly, certain provisions of this Part apply to development in all areas of the City, including outside of mapped special flood hazard areas.

Full Breakdown

Part 2C of Chapter 63, adopted by Ordinance No. 2018-27 in 2018 and amended in 2021, sets out the City's Floodplain Regulations alongside Chapter 65 Parts 6D and 6E. 22. Subsection (d) ties enforcement to the Florida Building Code, using ASCE 24 as the flood-resistant design standard the Building Code references. The 'Warning' clause in (e) makes clear the regulations set only a minimum reasonable standard, larger floods can and will occur, and the City disclaims any guarantee that mapped flood hazard areas or compliant construction will stay flood-free.

222 requires permits for regulated development. 224. Because flood hazard maps and base flood elevations can be revised by FEMA, the City periodically updates these regulations to remain eligible for the National Flood Insurance Program.

Violations & Fines

Development in a flood hazard area, including subdivisions, grading, manufactured-home placement, tank installation, or pool construction, without the permit required by § 63.222 is a violation of Part 2C, separately enforceable under § 63.224 for work not already covered by the Florida Building Code's own violation provisions. Noncompliant development can face permit denial, stop-work orders, or code enforcement action until it meets the Floodplain Regulations.

Frequently Asked Questions

What triggers Orlando's floodplain regulations?

Any development wholly or partially within a mapped flood hazard area, subdividing land, grading, building or altering a structure exempt from the Florida Building Code, placing a manufactured home or tank, siting a recreational vehicle, or installing a pool, falls under § 63.220's Floodplain Regulations.

Do Orlando's flood rules ever apply outside the mapped flood zone?

Yes. Section 63.220(b) says certain provisions apply citywide, including outside mapped special flood hazard areas, when the regulation states so explicitly: for example, the § 63.226(d) building-elevation-above-street-crown requirement applies at all locations in the City.

Why does Orlando warn that its floodplain rules aren't a guarantee against flooding?

Section 63.220(e) states the required protection level is only 'the minimum reasonable for regulatory purposes' and that larger floods can and will occur; the City disclaims liability for flood damage resulting from reliance on the Part or decisions made under it.
