What's the difference? Two different designations for two different purposes

Though often mistaken for each other, flood zones and evacuation zones are not one in the same. They are two very different things that measure very different conditions. So, what makes them unique? And when do you use them?

Here is what you need to know:

Evacuation zones

Due to significant changes in the evacuation map in 2022, your evacuation zone may have changed or you may be in an evacuation zone for the first time. Please check your evacuation zone.

Evacuation zones are the areas that officials may order evacuated during a hurricane. These zones are mapped by the National Hurricane Center and identify areas that will be affected by storm surge - storm-driven waves that can inundate a community and threaten lives.

Zones in Hillsborough County are identified from A to E, and there are parts of the county that are not in an evacuation zone.

Flood zones

These federally identified zones indicate a property's risk for flooding at any time of the year, including as a result of heavy or steady rain. This zone has nothing to do with hurricanes or other emergencies, and everything to do with your property insurance and building requirements. Nationally, these zones are classified as Zones A (Special Flood Hazard Area), B, C, D, V and X. Every property is in a flood zone.

Find my flood zone

Interestingly, a home may be in a non-evacuation zone, but still be in a high-risk flood zone because of a nearby pond or stream. Alternatively, a home could be in a low-risk flood zone, but still in an early evacuation zone because of storm surge projections or high winds.

That's why it's important to know both your flood zone and your evacuation zone, and the difference between them. Still unsure?

When to check the Evacuation Zone map

  • Before hurricane season to make sure your family prepared
  • During a hurricane or major storm, to know if you should evacuate

When to check the Flood Zone map

You own, rent, or are buying a new property and don't know if you need flood insurance

  • You refinance or get a mortgage
  • You need building permits for work on your property
  • You live in a low-lying area or near a stream, pond or body of water
