More from Ready.gov ↗
When the river rises
  • Turn around at flooded roads: a foot of moving water can carry off a car.
  • Flood insurance usually takes 30 days to start, so buy it before the forecast.
  • Keep papers and medicines up high, in a grab-and-go bag.
More from Ready.gov ↗
When the tide surges
  • Know your evacuation zone and the way off the coast.
  • Storm surge comes fast: leave when you’re told, not when the water arrives.
  • Move cars to high ground before king tides and nor’easters.
More from Ready.gov ↗
Before you buy or rent
  • Look up the address on FEMA’s flood map.
  • Ask the seller or landlord whether it has ever flooded, and what flood insurance costs there.
  • Get a flood insurance quote early: policies usually start 30 days after you buy.

How to read this page

What these numbers can and can’t tell you

  • An average, not a forecast. FEMA’s National Risk Index estimates the damage 18 kinds of natural hazards cause in a typical year, from decades of records and models. A quiet decade can follow a bad year.
  • Compared by rate. “Higher than N%” compares yearly damage as a share of what’s there, so a big city isn’t rated riskier just for having more buildings.
  • Money that reached town. Flood claims are matched to Allen’s own flood-insurance community; household aid to the registrant’s city; repair grants to Allen.
  • It follows property value. FEMA’s model weighs damage to buildings, so a place that recently lost many homes can rate lower than it feels.
