Flood Zones

The Florida Keys, Monroe County, Florida

Pretty much all areas of Monroe County - The Florida Keys are in a Flood Zone.  Determining flood risk is based on the elevation of the property and other variables surrounding the land.  Flood Maps are used to determine which Flood Zones are associated with a particular property.  These zones may vary on any particular site.

High Risk Areas
In high-risk areas, there is at least a 1 in 4 chance of flooding during a 30-year mortgage. All home and business owners in these areas with mortgages from federally regulated or insured lenders are required to buy flood insurance. They are shown on the flood maps as zones labeled with the letters A or V.
Moderate to Low Risk Areas
In moderate-to-low risk areas, the risk of being flooded is reduced but not completely removed. These areas submit over 20% of NFIP claims and receive one-third of disaster assistance for flooding. Flood insurance isn’t federally required in moderate-to-low areas, but it is recommended for all property owners and renters. They are shown on flood mapsas zones labeled with the letters B, C or X (or a shaded X).
Undetermined Risk Areas
No flood-hazard analysis has been conducted in these areas, but a flood risk still exists. Flood insurance rates reflect the uncertainty of the flood risk. These areas are labeled with the letter D on the flood maps.


Definition/Description (FEMA)

Flood hazard areas identified on the Flood Insurance Rate Map are identified as a Special Flood Hazard Area (SFHA). SFHA are defined as the area that will be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year. The 1-percent annual chance flood is also referred to as the base flood or 100-year flood. SFHAs are labeled as Zone A, Zone AO, Zone AH, Zones A1-A30, Zone AE, Zone A99, Zone AR, Zone AR/AE, Zone AR/AO, Zone AR/A1-A30, Zone AR/A, Zone V, Zone VE, and Zones V1-V30. Moderate flood hazard areas, labeled Zone B or Zone X (shaded) are also shown on the FIRM, and are the areas between the limits of the base flood and the 0.2-percent-annual-chance (or 500-year) flood. The areas of minimal flood hazard, which are the areas outside the SFHA and higher than the elevation of the 0.2-percent-annual-chance flood, are labeled Zone C or Zone X (unshaded).

Property Inquiries
Monroe County encourages inquiries from lenders, real estate representatives, insurance agents, and property owners to request flood information before buying or selling land in the county. All of Monroe County is identified as a coastal floodplain and may be subject to flooding.

Structures Below Base Flood Elevation
Monroe County enforces Monroe County Code Chapter 122 - Floodplain Management. Structures built after December 31, 1974, must have the lowest floor elevated to or above the base flood elevation. The owner or purchaser of a structure with habitable space below the base flood elevation may be faced with significant unforeseen expenses.

Legally permitted enclosures below the base flood elevation are for limited storage and parking only. Limited storage means storage of lawn mowers, rakes, wheelbarrows, and similar pieces of equipment that are normally stored outside. Limited storage does not apply to household furnishings, workbenches, freezers, refrigerators, or other items subject to damage if exposed to salt water. If you are purchasing a home with a finished enclosure below the base flood elevation, it may not be permitted construction and may be subject to enforcement proceedings.

National Flood Insurance Program
Monroe County is participating in the National Flood Insurance Program's (NFIP) flood inspection procedure. The process began in March of 2002. All structures that have opaque wall enclosures below base flood elevation that are insured under the NFIP are subject to this inspection process. Inspections began with the most current enclosures and will work back to the effective date of Monroe County’s participation in the NFIP, which was January 1, 1975.
