Oregon Revised Statutes Highways, Roads, Bridges and Ferries § 381.227

Whenever any county undertakes the construction or acquisition of an interstate bridge or ferry pursuant to ORS 381.205 to 381.305, the county court or board of county commissioners may employ and pay reasonable compensation to attorneys, including the district attorney of the county, for services heretofore or hereafter performed in connection with the construction or acquisition of such bridge or ferry. Such compensation, which in the case of the district attorney shall be in addition to any other compensation allowed by law, shall be payable solely out of the funds received from the sale of bonds for the construction or acquisition of the bridge or ferry or the revenues derived from the operation thereof.
