Coastal floodingHurricanesAvalanchesTsunamisVolcanic activity
People, not buildings.Counting harm to people as well as buildings, FEMA’s model puts drought at 28% of St. John’s expected losses. Drought does 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.

In dollars, FEMA expects about $2.1M a year in losses across St. John: $601K to buildings, the rest to people and crops.

Shared tract.All of St. John’s 1,228 residents (2020 census) live in one census tract, which it shares with Farmington township (521 residents) and Macksville city (471 residents) and Douglas township (118 residents) and Lincoln township (88 residents) and Cleveland township (65 residents) and Richland township (63 residents) and Albano township (28 residents) and Radium city (26 residents) and Clear Creek township (21 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.
A shared figure. The grade describes the whole tract, not each street in it, and FEMA’s model is an average year for today’s buildings, not a record: the claims below are the record.
