Oregon Revised Statutes Utility Regulation § 772.105

(1) When it is necessary or convenient in the location of any railway to appropriate any part of any public road, street, alley or public grounds not within the corporate limits of a municipal corporation, the county court of the county wherein such road, street, alley or public grounds is located, may agree with the corporation constructing the road, upon the extent, terms and conditions upon which the same may be appropriated or used, and occupied by such corporation. If the parties are unable to agree, the corporation may appropriate so much thereof as is necessary and convenient in the location and construction of the road.

(2) Whenever a private corporation is authorized to appropriate any public highway or grounds as mentioned in subsection (1) of this section, within the limits of any town, whether incorporated or not, such corporation shall locate their road upon such particular road, street, alley or public grounds, within such town as the local authorities designate. If the local authorities fail to make such designation within a reasonable time when requested, the corporation may make such appropriation without reference thereto.
