ORS § 777.165
Notwithstanding ORS 198.320, the Governor may fill vacancies on the board of any port by appointment when the vacancies exist as a result of the failure to nominate and elect board members as provided in ORS 777.080, 777.135 and 777.160. The appointees shall be electors registered in the port. If the port is divided into subdistricts under ORS 777.155 or 777.326, the appointees shall be electors registered in the subdistrict represented by the vacant position. The terms of the appointees shall be determined by lot at a meeting of the board held within five days after the appointment. However, the term of an appointee shall expire on June 30 next following the succeeding regular district election at which a successor is elected. The terms of the appointees shall be arranged with the terms of the other members so that the terms of not more than three commissioners expire on June 30 next following any regular district election.
