Insurance, in plain English
Flood insurance: the basics
The map can affect a lender’s insurance requirements, but the zone is not the only thing that matters. Here are the practical facts to know.
Homeowners insurance is different
Homeowners policies generally do not cover flood damage. Flood insurance is typically a separate policy.
A lender may require coverage
Flood insurance is generally required for a building in a Special Flood Hazard Area when the mortgage is federally backed, regulated, or insured. A lender can still require coverage in another zone.
Zone X is not zero risk
Federal mandatory-purchase rules generally do not apply outside the Special Flood Hazard Area, but a property in Zone X can still flood and flood coverage is still available.
What the common flood-zone letters mean
A flood-zone letter is helpful, but it is not the whole story. Also review the seller’s disclosure, elevation information, neighborhood drainage, past flooding, and a current insurance quote.
Zone AE
A high-risk flood area with a published Base Flood Elevation.
Zone A
A high-risk flood area without a published Base Flood Elevation. An elevation certificate may be especially useful.
Zone X, shaded
A moderate mapped-risk area. Flood insurance may not be required by a federally regulated lender, but the property can still flood.
Zone X, unshaded
A lower mapped-risk area for the flood source FEMA studied. It does not mean “no risk,” and it does not mean the property can never flood.
Does Zone X mean a home will never flood?
No. Zone X describes lower or moderate mapped risk for the flood source FEMA studied. Heavy rain, drainage problems, street flooding, and other conditions can still affect a property.
Look beyond the map
- Has the home or property ever taken water?
- Is an elevation certificate available?
- How does the street and neighborhood drain during heavy rain?
- What would flood insurance cost for this specific property?
Local note: Flood-zone research matters throughout Baton Rouge, Prairieville, Ascension Parish, and Livingston Parish. Two nearby properties can have different mapped information or elevation details.
