In Columbia County, flood and landslide screening starts with the address
HazVu gives an address-based first look and warns that hazard mapping is incomplete; county pages supply the local next step.
The preparation guidance is stable, but the map, alert, restriction, or condition may change. Last reviewed against the listed sources August 12, 2026.
Begin with the exact Columbia County address. DOGAMI HazVu can show mapped flood and landslide layers. It uses DOGAMI’s best maps, but some hazards are not fully mapped. A blank area is not a finding that the property is safe.
Use Columbia County’s hazard page for the next check. For a flood check, it points to FEMA’s local maps or local emergency staff. For a slide risk, it calls for a ground check and help from a trained expert.
Office jurisdiction matters too. Land Development Services handles land use, zoning, permits, building, and lot splits on land outside cities. Do not send every county address there without checking whether the property is inside a city. Start with the address, then check the mapped layer and the responsible local office before making a property decision.

Search the address in HazVu, review the county's flood and landslide guidance, and use Land Development Services for property in unincorporated Columbia County.
