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 Collinsville’s own flood-insurance community; household aid to the registrant’s city; repair grants to Collinsville.
  • 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. Across Collinsville, expected losses total about $2.2M a year, counting buildings, people and crops.
