ORS § 777.455
A port may, in accordance with ORS 777.455 to 777.505, issue refunding bonds for the purpose of refunding and retiring all or any part of its outstanding bonds when the holders are willing to surrender such bonds. When judgment is taken against a port based on bonds and interest coupons issued by the port, refunding bonds may be issued to provide funds with which to pay such judgment. Such bonds may be issued, pursuant to an ordinance or resolution adopted by the board, without elector approval. Such bonds may be issued in the full amount of the outstanding bonds and any judgment on bonds and interest coupons less any sinking funds applicable thereto. The full faith and credit of the issuing port shall be pledged to the payment of the principal of and interest on each of such bonds. Debt limitations imposed by law do not apply to refunding bonds.
