What stands out about Columbia’s natural hazards
From FEMA’s model and FEMA’s records, below.
What Columbia faces
Each hazard’s share of the building damage FEMA expects here, and how its rate compares with the rest of the country.
Hurricanes
River and rain flooding
Hail
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 Columbia’s grade
Hurricanes are 41% of the building damage FEMA expects in Columbia, and Columbia’s rate of hurricanes damage is in the top 8% of U.S. census tracts. Hail adds 10%, at a rate in the top 5% of U.S. census tracts.
C− #72 of 101 in Mississippi; higher expected damage per building than 82% of U.S. towns (21,298).
Columbia’s residents live in 4 census tracts; FEMA’s figures are combined by where they live.
The typical Mississippi town has higher expected damage than 64% of U.S. towns; within the state, Columbia has more expected damage per building than 71% of Mississippi towns.
In dollars, FEMA expects about $4.2M a year in losses across Columbia: $3.5M to buildings, the rest to people and crops.
