In Benton County, a flood and landslide screen starts with the address

Use DOGAMI HazVu as a first screen, then read SLIDO's limits. If Community Development handles the property, bring the assessor's map and tax lot number for county flood records.

The preparation guidance is stable, but the map, alert, restriction, or condition may change. Last reviewed against the listed sources August 12, 2026.

Start with the exact Benton County address. Enter it in DOGAMI HazVu. Turn on both the 100-year flood and landslide layers. HazVu uses DOGAMI’s best available maps. DOGAMI warns that not every hazard has been fully mapped. A blank patch does not settle a property decision.

Open SLIDO for more landslide detail. DOGAMI does not intend SLIDO for planning one site. It does not replace a site study by a qualified practitioner. If Community Development handles the property, bring the assessor’s map and tax lot number. The office can check the flood map and zone. It may also have an approximate base flood elevation or a filed elevation certificate.

Land outside the mapped flood area can still flood. That is especially true near a map edge or known water problem. Before a site decision, check the county file and get the site study the decision calls for.

Use this for

Search the address in HazVu, treat SLIDO as a screening tool, and ask Community Development about flood information filed for the assessor's map and tax lot.
