The agricultural valleys of Washington County are centered here at the confluence of the Tualatin River and its many tributaries, including Dairy Creek and Council Creek. This landscape is defined by the established communities of Forest Grove and Cornelius, where the presence of the Southern Pacific RR and Oregon Electric RR signals the historical importance of rail transport for the region's timber and farm exports. Smaller Catholic settlements like Verboort and Roy reflect the area’s local history, anchored by institutions such as Visitation Church and St Francis School.
