Willamette Valley • County seat: Corvallis

Benton County climbs from the Willamette River at Corvallis west into the Coast Range, where Marys Peak stands above the valley. The valley floor is flat, while the foothills and forested ridges bring steep slopes within a few miles.

Coverage details are temporarily unavailable.

Property boundaries

The county assessor’s parcel service for Benton County is not available in the Property tool yet, so taxlots cannot be selected here. Draw your area on the map instead; the parcel lines overlay still shows taxlot lines.
