Colorado land market report
Colorado land, county by county: what sold, and how much is in a flood zone. Every figure from county tax rolls and public maps, with its months.
Land prices
No price per acre: no Colorado county's recorded land sales have passed the per-acre price test this report prints by. Parcel cards in 6 counties carry a price range tested on past sales.
How much is in a flood zone
4.1% of parcels in the 37 counties on FEMA's digital flood map sit in a FEMA special flood hazard area. 1.1% of parcels are a quarter or more wetland (National Wetlands Inventory, 49 counties).
Share of each county's parcels in FEMA's 1%-annual-chance flood zone, highest first. Cheyenne, Costilla, Custer, Dolores, Huerfano, Lake, Moffat, San Miguel and Yuma counties are not on FEMA's digital flood map; they are left out. Only part of Garfield, Sedgwick and Washington counties are on FEMA's digital flood map; they are left out of the shares.
