Oregon Revised Statutes Highways, Roads, Bridges and Ferries § 376.785

(1) If following the hearing the legislative body shall determine that the pedestrian mall shall be established, and if at that time there remain any written claims for damages which have not been allowed pursuant to ORS 376.770 or which have not been withdrawn, the legislative body shall direct that an action or actions be brought in the circuit court of the county in which the city is located in the name of the city by the city attorney, for a determination of the damages, if any, to which the claimant may legally be entitled because of the establishment of the pedestrian mall. Such action shall be in the nature of a proceeding in eminent domain for the condemnation of the right or rights in real property, the taking of which by the establishment of the pedestrian mall results in the damages claimed. In such action the amount set forth in the claim relating thereto shall not constitute a limitation upon the amount which may be pleaded, proved or recovered.

(2) Except as may otherwise be provided in ORS 376.705 to 376.825, such action and proceeding shall be governed so far as the same may be made applicable by those provisions of ORS chapter 35 relating to actions and proceedings in eminent domain. In any such action the resolution adopted under ORS 376.780 (1) shall be conclusive evidence of the public necessity of the proposed pedestrian mall; that the property or rights in property to be taken are necessary therefor, and that the pedestrian mall is planned and located in the manner which will be compatible with the greatest public good and the least private injury.

(3) The judgment in any such action shall be satisfied and a final order taken before vehicular traffic is prohibited, in whole or in part, on the pedestrian mall pursuant to ORS 376.705 to 376.825.
