Recorded flood claims in Arapahoe County
FEMA counts claims on buildings with NFIP flood insurance, so land without an insured building never shows here. Claims counted from 1978 to Sep 2026.

What Groundwork can price in Arapahoe County
Price range for a home with its land, or for land (tested on past sales; final check due Jun 2027): 22,084 parcels. Rough estimate for a home with its land, or for land: 139,273 parcels. Facts only: 3 parcels.
The card's own words; a card whose range covers a home with its land says “home + land”. Figures are on the card, never on this page.
Land sale prices
We hold this county's recorded deeds, but its file does not mark which sales are arm's-length land sales, so this page prints no land price range yet.
