What stands out about Eureka’s natural hazards
From FEMA’s model and FEMA’s records, below.
What Eureka 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
Wildfire
Earthquakes
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 Eureka’s grade
River and rain flooding is 57% of the building damage FEMA expects in Eureka, and Eureka’s rate of river and rain flooding damage is lower than 68% of U.S. census tracts. Wildfire adds 36%, at a rate in the top 2% of U.S. census tracts.
B lower expected damage per building than 62% of U.S. towns (21,298).
Eureka’s residents live in 2 census tracts; FEMA’s figures are combined by where they live.
In dollars, FEMA expects about $622K a year in losses across Eureka: $438K to buildings, the rest to people and crops.
Does Eureka flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Eureka. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Eureka isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.
