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.
River and rain flooding
Hurricanes
Earthquakes
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
River and rain flooding is 61% of the building damage FEMA expects in Columbia, and Columbia’s rate of river and rain flooding damage is lower than 61% of U.S. census tracts. Ice storms add 3%, at a rate in the top 7% of U.S. census tracts.
B #68 of 169 in South Carolina; lower expected damage per building than 60% of U.S. towns (21,298).
Columbia’s residents live in 66 census tracts; FEMA’s figures are combined by where they live.
The typical South Carolina town has lower expected damage than 55% of U.S. towns; within the state, Columbia has less expected damage per building than 60% of South Carolina towns.
Among the 400 U.S. cities of 100,000 or more, Columbia has lower expected damage per building than 72% (#112 of 400). Because it is so big, its total expected yearly loss, $46.5M, is the 265th largest of those 400.
