What Edison 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
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 Edison’s grade
River and rain flooding is 44% of the building damage FEMA expects in Edison, and Edison’s rate of river and rain flooding damage is lower than 82% of U.S. census tracts. Next is hurricanes at 37% (higher than 88% of U.S. census tracts).
B lower expected damage per building than 60% of U.S. towns (21,298).
All of Edison’s residents live in one census tract; the figures are that tract’s.
In dollars, FEMA expects about $739K a year in losses across Edison: $308K to buildings, the rest to people and crops.
Does Edison flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Edison. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Edison isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.
