Storms, floods and disasters in Anderson
Anderson isn’t graded for hazard risk: Anderson has 140 residents; we grade towns of 1,000 or more.
What Anderson faces
Each hazard’s share of the building damage FEMA expects here, and how its rate compares with the rest of the country.
Earthquakes
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.
Does Anderson flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Anderson. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
