What stands out about Tremont’s natural hazards
From FEMA’s model and FEMA’s records, below.
What Tremont 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
Coastal 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 Tremont’s grade
Hurricanes are 50% of the building damage FEMA expects in Tremont, and Tremont’s rate of hurricanes damage is higher than 89% of U.S. census tracts. Coastal flooding adds 21%, at a rate in the top 1% of U.S. census tracts.
B lower expected damage per building than 64% of U.S. towns (21,298).
