Flood Zones Versus Evacuation Zones

Did you know there are two types of zones, flood zones and evacuation zones? They are very different and measure conditions that may not occur at the same time.

Flood Zones

Flood zones are areas mapped by FEMA for use in the National Flood Insurance Program. Each flood zone designation, represented by a letter or letters, tells homeowners their risk for flooding on their property. Homes with a mortgage located in high risk areas must have flood insurance.

Evacuation Zones

Evacuation zones are based on storm surge zones determined by the National Hurricane Center. Santa Rosa County uses A - E to identify evacuation zones based on the areas that are likely to be affected by storm surge. Some areas of the county are not located in any evacuation zone. Also of note, a home may be located in a non-evacuation zone, yet still be located in a flood zone because of a nearby stream or pond. Citizens should check both zones for their property at Know Your Zone so they will understand what action they should take when safety directions are given by emergency management officials.
