A rating from 0 to 10 of how often the area around a property floods, where higher numbers mean the surrounding area floods less often. It reflects the area, not the individual home.
A low score does not always mean this home will flood. It might sit on higher ground and stay dry, but a nearby flood plain can still affect it a great deal, because flooding damages surrounding roads, utilities, and services and drags on value and insurance across the whole area. Use a low score as a prompt to look into whether this particular home is genuinely at risk.
In the United States this is the Joint Research Centre's river flood depths alone, so coastal flooding is not counted. Hawaii has no score.
