Recorded flood claims in Douglas 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.

Federal disaster declarations
Each federal declaration whose designated areas include the county, declared from January 2000 on, counted once by its FEMA disaster number. An emergency declaration and a major-disaster declaration for the same storm are two declarations, as FEMA numbers them. Declarations for tribal lands alone are not counted. The date shown is when the most recent incident began. Types are FEMA's incident types: an evacuation emergency for a storm elsewhere (Hurricane Katrina, 2005) counts under that storm. By kind: 3 major disasters, 4 emergencies and 2 fire-management declarations.

Home value trend in Douglas County
This tracks home values, not land values. Land buyers read it as a sign of demand nearby: where homes gain value, builders and buyers follow. A vacant lot can move differently.
How: the change in FHFA's annual county index from 2020 and 2024 to 2025, rounded. The index follows repeat sales and refinance appraisals of the same single-family homes with Fannie Mae or Freddie Mac mortgages. It is in today's dollars, not adjusted for inflation, and FHFA calls these local indexes developmental. Where FHFA's sample is too small it publishes no figure, and none prints here.

Development in Douglas County
Places are Census places (cities, towns and named communities), counted inside their limits. Counted from USGS Annual NLCD land cover (2015, 2020 and 2025; 30 m squares on a 240 m grid, so edges are approximate). A square counts when it was forest, shrub, grassland, pasture, cropland or wetland in the start year and developed in 2025 (NLCD's developed classes, from lawns and roads to dense buildings). A satellite land-cover map misses some changes and mislabels a few; read it as a guide.

What Groundwork can price in Douglas County
Rough estimate for a home with its land, or for land: 98,463 parcels. Facts only: 2,502 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.
