The official FEMA flood map for Martin County allows you to check an address to see if it lies within Flood Zone AE, Zone X, or coastal flood hazard areas like Zone V. These designations are important for insurance requirements. For example:

  • Flood Zone AE (Florida) → High-risk, mandatory insurance for most homeowners with a mortgage

  • Flood Zone X (Florida) → Considered low to moderate risk; lenders may not require coverage, but optional insurance is available

  • Flood Zone V (coastal) → High-risk with added velocity hazard from storm surge and waves

Flood zones are split based on risk. The different colors will lend varying risk and often mean that homeowners with a mortgage will have to carry certain levels of insurance coverage. Knowing if your house is in these Martin County flood zones could be the difference between a home seeming affordable or otherwise. Below is a list of risk break downs so you know what they mean when you see them on the flood zone map.

 

Moderate/Low Risk Flood Zone

Zones B & X, C & X

In Zone X flood zones in Florida, homeowners face a minimal to moderate risk. These are sometimes marked as “outside the 100-year floodplain.” While lenders usually don’t require flood insurance here, many experts recommend optional coverage since heavy rainfall and stormwater runoff can still cause flooding.

High Risk Flood Zone

Zones A, AE, A1-30, AH, AO, AR, A99

If your property lies in Flood Zone AE in Florida, or any of the other high-risk classifications (A, AH, AO, AR, A99), you are in an area with a 1% annual chance of flooding — also called the “100-year floodplain.”

  • Flood Zone A → No base flood elevation provided, but still high risk

  • Flood Zone AE → High risk with specific base flood elevations

  • Flood Zone AH/AO → Ponding or sheet flow flood risk

  • Flood Zone AR → Special flood zone with temporary increased risk

While many of these Martin County flood zone classifications vary, the important factor for homeowners is that they all require flood insurance coverage. A comprehensive breakdown of each of these zones can be found here: https://snmapmod.snco.us/fmm/document/fema-flood-zone-definitions.pdf. Many of the names address the base flood elevation and annual chance of flooding.

 

High Risk Flood Zone (Coastal Areas)

Zones V, VE, V 1-30

Homes in Stuart, Jupiter Island, Jensen Beach, and Sewall’s Point often fall into Zone V or VE. These areas carry mandatory flood insurance requirements and may also face higher premiums due to coastal erosion and storm surge exposure. Mandatory flood insurance will apply to anyone buying a waterfront home with a mortgage in these areas.
