What zone V means
Zone V is a coastal high hazard area: land along the coast with a 1% chance of flooding in any given year plus the added hazard of storm-induced velocity wave action. Waves hit buildings with far more force than still water.
V zones were mapped with approximate methods, so FEMA does not publish a base flood elevation for them. Zone VE is the same hazard mapped with a detailed study.
FEMA calls the flood with a 1% chance of being equaled or exceeded in any given year the "base flood" (often called the 100-year flood). A 1% chance each year adds up: over 30 years it works out to roughly a 26% chance of at least one such flood.
Insurance in zone V
This is a Special Flood Hazard Area (SFHA). Under federal law, if you have a mortgage from a federally regulated or insured lender — or a loan backed by FHA, VA, USDA, Fannie Mae or Freddie Mac — on a building in an SFHA in a community that participates in the National Flood Insurance Program (NFIP), the lender must require flood insurance. Your lender or a licensed agent can confirm what your loan requires.
Standard homeowners policies exclude flood damage. Flood coverage is bought separately, either through the NFIP or from a private flood insurer.
In coastal areas, wind and flood are usually separate questions: wind damage is often covered (sometimes with a separate hurricane or wind deductible, or through a state wind pool), while storm surge is flood. A licensed agent can explain how the two fit together for a specific home.
Reducing flood risk
- New and substantially improved buildings in V zones must be elevated on open foundations such as pilings or columns, so waves can pass underneath.
- Any walls enclosing the area below the lowest floor must be designed to break away under wave forces without damaging the building.
- Fill cannot be used for structural support in V zones.
- Raise utilities and use flood-resistant materials below the lowest floor.
Your community’s floodplain administrator can tell you which building requirements apply locally.
Zone V questions
- What does flood zone V mean?
- Zone V is a coastal high hazard area with a 1% annual chance of flooding plus storm-driven wave action. FEMA has not published a base flood elevation for it.
- What is the difference between V and VE zones?
- Both are coastal high hazard areas with wave action. VE zones were mapped with a detailed study and show a base flood elevation; V zones were mapped with approximate methods and do not.
