What stands out about Rockford’s natural hazards
From FEMA’s model and FEMA’s records, below.
What Rockford 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
Hail
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 Rockford’s grade
River and rain flooding is 81% of the building damage FEMA expects in Rockford, and Rockford’s rate of river and rain flooding damage is higher than 71% of U.S. census tracts. Next is tornadoes at 10% (higher than 79% of U.S. census tracts).
C+ #402 of 768 in Illinois; higher expected damage per building than 56% of U.S. towns (21,298).
Rockford’s residents live in 59 census tracts; FEMA’s figures are combined by where they live.
The typical Illinois town has higher expected damage than 54% of U.S. towns; within the state, Rockford has more expected damage per building than 52% of Illinois towns.
Among the 400 U.S. cities of 100,000 or more, Rockford has lower expected damage per building than 53% (#188 of 400). Because it is so big, its total expected yearly loss, $58.2M, is the 212th largest of those 400.
