Oregon Revised Statutes Public Lands § 274.932

(1) Whenever a public body, in accordance with ORS 274.920, creates new lands upon submersible or submerged lands owned by the state, the public body has the right to purchase the new lands as provided in this section. The public body shall pay to the Department of State Lands for the new lands the value of the state-owned submersible or submerged lands upon which the new lands were created immediately prior to the creation of the new lands thereon and an amount prescribed by the department to pay its administrative costs incurred with respect to the new lands. Such payment shall be made by the public body within one year after the date of the receipt by it of actual notice by the department of the creation of the new lands, the value of the state-owned submersible or submerged lands upon which the new lands were created and the administrative costs incurred by the department with respect to the new lands. If the public body fails to make payment for the new lands as provided in this subsection within one year after the date of the notice by the department, the department may dispose of the new lands as provided in ORS 274.915.

(2) If a public body and the department cannot agree on the value of the state-owned submersible or submerged lands upon which the new lands were created under subsection (1) of this section, the value shall be determined by three appraisers, one appointed by the public body, one appointed by the department and the third appointed by the first two. The determination of the appraisers shall be final. The cost of the third appraiser shall be borne equally by the public body and the department.
