FEMA flood Zone V
High-risk coastal (SFHA) · Special Flood Hazard Area · annual chance 1% (100-year) + wave action
Zone V is a high-risk coastal (sfha) FEMA flood-map designation. Coastal areas subject to inundation by the 1-percent-annual-chance flood event with additional hazards from storm-induced waves (velocity hazard). No detailed Base Flood Elevations are shown. Zone V is a Special Flood Hazard Area and is among the highest-risk designations. Because it is a Special Flood Hazard Area, flood insurance is mandatory for a building with a federally backed mortgage.

What Zone V means for your flood insurance
Flood insurance is mandatory for federally backed mortgages. Coastal velocity zones carry the highest premiums because of wave damage potential; elevation on piles and breakaway walls is required.
Under Risk Rating 2.0, FEMA prices each property on its own flood risk — distance to water, flood type, foundation, the height of the lowest floor and rebuild cost — rather than charging one flat rate per zone. So the zone tells you whether insurance is mandatory and roughly how risky the area is, while your actual premium is property-specific. See the cost estimator for a rough figure.
