Recorded flood claims in Dayton
Fewer than 10 insured flood claims were recorded in and around Dayton from 1978 to Sep 2026. FEMA counts claims on buildings with NFIP flood insurance, so land without an insured building never shows here.
Counted in the 2 census block groups that lie mostly inside Dayton, so the edges may reach past the town line. This product uses the Federal Emergency Management Agency's OpenFEMA API, but is not endorsed by FEMA. The Federal Government or FEMA cannot vouch for the data or analyses derived from these data.
