What stands out about Charleston’s natural hazards
From FEMA’s model and FEMA’s records, below.
What Charleston 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
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 Charleston’s grade
River and rain flooding is 97% of the building damage FEMA expects in Charleston, and Charleston’s rate of river and rain flooding damage is in the top 3% of U.S. census tracts.
D #49 of 61 in West Virginia; higher expected damage per building than 91% of U.S. towns (21,298).
Charleston’s residents live in 25 census tracts; FEMA’s figures are combined by where they live.
The typical West Virginia town has higher expected damage than 73% of U.S. towns; within the state, Charleston has more expected damage per building than 80% of West Virginia towns.
