South Deerfield isn’t graded for hazard risk: South Deerfield is a Census area inside a town, graded with the town.
What South Deerfield 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
Hurricanes
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.
Does South Deerfield flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in South Deerfield. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
South Deerfield isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.
