Coastal floodingHurricanesAvalanchesTsunamisVolcanic activity
People, not buildings.Counting harm to people as well as buildings, FEMA’s model puts cold waves at 12% of Parker’s expected losses. Cold waves 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 Parker’s 1,194 residents (2020 census) live in one census tract, which it shares with Marion city (849 residents) and Home township (359 residents) and Germantown township (336 residents) and Chancellor town (300 residents) and Parker township (275 residents) and Monroe township (210 residents) and Marion township (189 residents) and Brothersfield township (181 residents) and Monroe town (159 residents) and Rosefield township (137 residents) and Dolton township (110 residents) and Dolton town (34 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.
