Oregon Revised Statutes Highways, Roads, Bridges and Ferries § 376.510

Any such person, firm or corporation has the right to acquire and own all lands reasonably necessary for the logging road or way to promote the transportation of logs or the raw products of the forest. If such person, firm or corporation is unable to agree with the owners of the land over which the logging railroad is necessary, as to the amount of compensation to be paid therefor, such person, firm or corporation has the right to condemn so much of the land necessary for the logging railroad, road or ways as may be necessary for the use thereof, and may maintain the suit for condemnation in the circuit court of the county wherein the lands are located. No land shall be taken until compensation has been assessed and tendered.
