FEMA Flood Zone & Flood Review FAQs
What exactly is a FEMA Flood Zone?
FEMA Flood Zones are geographic areas that FEMA has defined according to varying levels of flood risk. These zones are depicted on a community's Flood Insurance Rate Map (FIRM) or Flood Hazard Boundary Map. Each zone reflects the severity or type of flooding in the area. The maps can be found on FEMA's website in their Map Service Center.
What is the Base Flood Elevation (BFE)?
The BFE is the elevation to which floodwater is anticipated to rise during the base flood (the 1% annual chance flood). BFEs are shown on Flood Insurance Rate Maps (FIRMs) and are the source for flood insurance rating and the basis for local floodplain management regulations.
How does a Letter of Map Amendment (LOMA) work?
A LOMA is a letter from FEMA stating that an existing structure or parcel of land that is high enough and is not inundated by the base flood was inadvertently included in a Special Flood Hazard Area (SFHA). A LOMA can potentially:
- Remove the federal flood insurance requirement
- Correct inaccurate map designations
- Help reduce property-specific insurance costs
What is a Special Flood Hazard Area (SFHA)?
The SFHA is the land area covered by the floodwaters of the base flood. In these areas, the NFIP’s floodplain management regulations must be enforced and the mandatory purchase of flood insurance applies for federally backed mortgages. Zones starting with A or V are within the SFHA.
Is my home considered 'high risk' if it is in Zone AE?
Yes. Zone AE is high-risk and represents areas with a 1% annual chance of flooding where BFEs have been determined. While considered high risk, it doesn't mean your property will flood immediately, but it does carry significant regulatory and insurance implications.Â
What is the difference between 'Effective' and 'Preliminary' maps?
Effective maps are the current regulatory maps for insurance and permits. Preliminary maps are updated versions provided by FEMA for review before they become law. Our reports check both to see if your risk profile is expected to change soon.
