ORS § 545.126
ORS 545.097 to 545.126 shall not operate to release any lands excluded from the district from any lien on the lands or any obligation to pay any valid outstanding bonds or other indebtedness of the district at the time of the filing of the petition for exclusion of the lands. The lands shall be held subject to the lien, and answerable and chargeable for the payment and discharge of all outstanding obligations at the time of the filing of the petition, as fully as though the petition were never filed and the order of exclusion never made. If lands were subdivided into small tracts of less than one acre after the bonded indebtedness is apportioned to the lands on a per acre basis, the required payments shall be computed to the nearest one-tenth acre. For the purpose of discharging the outstanding indebtedness, the lands so excluded shall be considered part of the irrigation district. Notwithstanding the exclusion of land from the district, all provisions otherwise available to compel the payment by the land of its quota or portion of the outstanding obligation if the exclusion had never been accomplished, may be resorted to in order to compel and enforce the payment by the land of its quota or portion of the outstanding obligations of the irrigation district for which it is liable. However, the land excluded shall not be held answerable or chargeable for any obligation incurred after the filing of the petition for exclusion. This section shall not apply to any outstanding bonds or other obligations or indebtedness the holders of which have assented to the exclusion of such lands from the district.
