What stands out about Antioch’s natural hazards
From FEMA’s model and FEMA’s records, below.
What Antioch faces
Each hazard’s share of the building damage FEMA expects here, and how its rate compares with the rest of the country.
River and rain flooding
Tornadoes
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.
What’s behind Antioch’s grade
River and rain flooding is 88% of the building damage FEMA expects in Antioch, and Antioch’s rate of river and rain flooding damage is higher than 71% of U.S. census tracts. Next is tornadoes at 9% (higher than 72% of U.S. census tracts).
B− #331 of 768 in Illinois; lower expected damage per building than 50% of U.S. towns (21,298).
Antioch’s residents live in 6 census tracts; FEMA’s figures are combined by where they live.
