Score flood description

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.

  • 0-2: Very high flood exposure - The surrounding area floods readily
  • 3-4: High flood exposure - The area sees significant flooding
  • 5-6: Moderate flood safety - Some flood-prone conditions nearby
  • 7-8: High flood safety - The area floods only rarely
  • 9-10: Very high flood safety - The surrounding area is very unlikely to flood

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.
