Mendeltna and its neighbors
Mendeltna has the lowest rating of the 3 towns around it. Tap a town to see its hazards.
Rating = expected yearly storm and flood damage as a share of what’s there, vs. U.S. communities. Flood claims = paid federal flood insurance claims on record.
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 Mendeltna’s own flood-insurance community; household aid to the registrant’s city; repair grants to Mendeltna.
- 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.
