What Plymouth faces
Each hazard’s share of the building damage FEMA expects here, and how its rate compares with the rest of the country.
Wildfire
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.

Wildfire is 53% of the building damage FEMA expects in Plymouth, and Plymouth’s rate of wildfire damage is in the top 1% of U.S. census tracts. Next is river and rain flooding at 46% (higher than 78% of U.S. census tracts).
D higher expected damage per building than 90% of U.S. towns (21,298).
