Is Poquoson city, VA in a flood zone?
FEMA's National Risk Index puts Poquoson city's flood hazard at the 62.4th percentile nationally — a middling flood hazard by national standards — driven by coastal storm surge rather than inland rivers — FEMA's model puts a surge event here at about 3.7 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
