Recorded flood claims in Walnut Hill
Fewer than 10 insured flood claims were recorded in and around Walnut Hill 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 1 census block group that lies mostly inside Walnut Hill, so the edges may reach past the town line.
