Coastal floodingHurricanesTsunamisVolcanic activity
People, not buildings.Counting harm to people as well as buildings, FEMA’s model puts avalanches at 9% of Story’s expected losses. Avalanches do little damage to buildings (0.0%), so they aren’t part of the grade.

Shares are of FEMA’s expected building damage, the measure the grade uses; ranks compare each hazard’s building-damage rate with all 85,154 U.S. census tracts. In FEMA’s terms, river and rain flooding is FEMA’s “Inland Flooding” (rivers and streams overflowing their banks, or rain overwhelming drainage). FEMA defines coastal flooding as high or rising tides and storm surge, so surge damage is counted there. Drought isn’t listed: FEMA counts its losses in crops only.

Flood risk changes street by street. Check a specific address on FEMA’s flood map, and ask about flood insurance before you buy.

Shared tract.All of Story’s 903 residents (2020 census) live in one census tract, which it shares with Clearmont town (116 residents) and Arvada CDP (33 residents). FEMA publishes its model by tract, so the rate and the hazard mix are the tract’s, the same for all of them. The flood claims below are the town’s own.

Flood insurance claims

Does Story flood? No paid flood claims on record

FEMA’s records show no paid flood insurance claims in Story. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
