Honomu isn’t graded for hazard risk: Honomu has 376 residents; we grade towns of 1,000 or more.
What Honomu 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
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.
Does Honomu flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Honomu. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Honomu isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.
