Oregon Revised Statutes Water Resources: Irrigation, Drainage, Flood Control, Reclamation § 545.099

(1) The owners in fee of one or more tracts of land or the holders of an uncompleted title to government or state lands which constitute a portion of an irrigation district may jointly or severally file with the board of directors a petition requesting that those tracts be excluded and taken from the district. The petition shall state the grounds upon which it is requested that the lands be excluded. The petition shall also describe the boundaries of the tracts sought to be excluded and the lands of the petitioners which are included within those boundaries. The description of the lands need not be more particular or certain than is required when the lands are entered in the assessment book by the county assessor.

(2) Upon receipt of a petition for exclusion, the board of directors shall review the petition and shall enter its order approving the petition. The board may approve the petition subject to the requirements of ORS 545.051, 545.097 or 545.126 or may approve the petition without conditions, as the board considers appropriate. The board, as a condition of exclusion, may require the petitioners to pay all costs of exclusion, including but not limited to recording fees, a reasonable administrative fee and all past due charges and assessments of the district attributable to the petitioners and the lands of the petitioners. When any district facilities, including but not limited to ditches, pipelines, headgates or other waterworks, are on the lands of the petitioners, if the petitioners propose to change the use of the land, the district may require the petitioners to provide measures to protect those facilities and may require that appropriate easements be provided if there are none of record.
