How to read this page

An average, not a forecastFEMA’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 here, so a big city isn’t rated riskier just for having more buildings. Royal Oak covers 18 census tracts, combined by population.
Money that reached townFlood claims are matched to Royal Oak’s own flood-insurance community; household aid to the registrant’s city; repair grants to the City of Royal Oak. FEMA’s model follows property values, so a place that recently lost many homes can rate lower than it feels.

FEMA’s expected losses across Royal Oak total about $15.7M a year, counting buildings, people and crops.
