Oregon Revised Statutes Highways, Roads, Bridges and Ferries § 371.635

(1) If the number of objections mentioned in ORS 371.630 is not received, the county court may, by order describing the land to be assessed, direct the improvement to be made by contract, or by force account. If by contract, it shall be awarded in the same manner as provided for other contracted county road improvement.

(2) The county court shall record the order for the improvement with the county clerk. The recorded order is notice that the land described in the order is subject to a lien of an assessment for the cost of the improvement, in an amount to be determined later by an order of the county court. The county clerk shall indorse upon the order the date of the filing thereof, and shall record and index the same in the County Clerk Lien Record.

(3) If the proposed improvement described in the order of the county court is not commenced within two years after the order for the improvement is recorded, the county court may by a new order vacate its former order for the proposed improvement. The county court shall record with the county clerk the order vacating the former order for the proposed improvement. Thereupon the land described shall be free of such lien and the effect of the former order. The county clerk shall indorse upon the new order the date of the filing thereof, and shall record and index the same in the County Clerk Lien Record.
