Types of Flood Zones in Martin County
Martin County employs the Federal Emergency Management Agency's (FEMA) flood zone designations to identify areas prone to flooding. You can view the National Flood Hazard Layer map to enter your address. The flood zones are categorized as follows:
High-Risk & Coastal High-Risk Flood Zones (Special Flood Hazard Areas – SFHAs)
This represents areas at high risk of flooding due to storm surges, heavy rainfall, or nearby water bodies. Property owners within this zone should consider obtaining flood insurance if it is not mandated by their lender. Some zones are also known as Special Flood Hazard Areas (SFHA).
Zone A, Zone AO, Zone AH, Zones A1-A30, Zone AE, Zone A99, Zone AR, Zone AR/AE, Zone AR/AO, Zone AR/A1-A30, Zone AR/A, Zone V, Zone VE, and Zones V1-V30
These zones are clearly marked on the Martin County flood map and FEMA flood zone map. Neighboring coastal communities such as Sewall’s Point and Port Salerno often have large areas designated as VE or AE zones, requiring flood insurance for homeowners and commercial properties.
Moderate Risk Flood Zones
If you are buying Martin County real estate that has this flood zone type, flood insurance is available but usually will not be required by a lender. These areas may be within the area that FEMA believes could experience a flood within 100 to 500 years.
Zone B or Zone X (shaded)
These are shown as shaded areas on FEMA maps and may appear on Indian River County flood zone maps, Palm Beach County flood maps, or Vero Beach flood zone maps depending on your location.
Low Risk Flood Zones
These areas have elevations high enough to be outside of the 0.2% annual-chance-flood, or 500-year flood. Keep in mind that flooding can still occur in these zones due to local drainage issues or intense rainfall.
Zone C or Zone X (unshaded)
While this is a general breakdown of the different flood zones in Martin County, you can always understand your flood zone more through government resources. More information about flood zone categories can be found through FEMA.
Even in low-risk flood zones like Zone C or Zone X (unshaded), property owners in North River Shores, Glen Ridge, or Ocean Breeze may choose optional flood insurance for extra protection.
