ORS § 456.110
For inefficiency or neglect of duty or misconduct in office, a commissioner of an authority appointed pursuant to ORS 456.095(1) or (2) may be removed by the mayor or, in the case of an authority for a county, by the governing body of the county or, in the case of a regional authority, by the appointing authority for the commissioner. This section does not allow the removal of a member of a governing body exercising power as a housing authority. A commissioner shall not be removed until after the commissioner has been given a copy of the charges at least 10 days prior to the hearing thereon and had an opportunity to be heard in person or by counsel. In the event of the removal of any commissioner, a record of the proceedings, together with the charges and findings thereon, shall be filed in the office of the clerk for each city and county in the authority.
