What stands out about Carmel’s natural hazards
From FEMA’s model and FEMA’s records, below.
What Carmel 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
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 Carmel’s grade
River and rain flooding is 71% of the building damage FEMA expects in Carmel, and Carmel’s rate of river and rain flooding damage is higher than 52% of U.S. census tracts. Tornadoes add 19%, at a rate in the top 5% of U.S. census tracts.
B #331 of 593 in Indiana; lower expected damage per building than 58% of U.S. towns (21,298).
