Data available for District of Columbia
- No free owner records. District of Columbia does not publish a free statewide parcel-and-owner dataset, so LandBenchmark cannot show who owns a parcel in District of Columbia. The county assessor's office is the authoritative source. Every measured signal below is unaffected.
- No township/range legal description. District of Columbia is a metes-and-bounds state with no PLSS grid.
- FEMA flood zones, wetlands, soil survey and NCCPI soil productivity — the federal layers, all free and all available here.
- 56 measured signals from satellite imagery and public records — slope and usable acreage, observed surface water, vegetation trend, wildfire and seismic hazard, access and neighbouring land use. Each one cites its method, its source, and the date it was observed.
LandBenchmark has no listings and does not know what is for sale in District of Columbia. It analyses a parcel you point it at. It is an automated Phase-1 desk screen, not a survey, a flood determination, or a substitute for on-site inspection.
