What stands out about Louisville’s natural hazards
From FEMA’s model and FEMA’s records, below.
What Louisville 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 Louisville’s grade
River and rain flooding is 69% of the building damage FEMA expects in Louisville, and Louisville’s rate of river and rain flooding damage is higher than 79% of U.S. census tracts. Tornadoes add 14%, at a rate in the top 3% of U.S. census tracts.
C− higher expected damage per building than 78% of U.S. towns (21,298).
All of Louisville’s residents live in one census tract; the figures are that tract’s.
In dollars, FEMA expects about $920K a year in losses across Louisville: $644K to buildings, the rest to people and crops.
