Iowa Code Title XI. Natural Resources [Chs. 455-485] § 468.629. Lost records--hearing

When the records of any mutual drain are incomplete or have been lost, or when the owner of any land affected by such mutual drain believes that the apportionment of costs or damages is inequitable or that repair or reconstruction is needed, such owner may petition the board of supervisors for relief. The board shall notify all affected parties of such petition, and set a date for a hearing on the petition. The board may adjourn the proceedings from day to day, but no adjournment shall be for more than ten days, and may order such engineering examinations, reclassifications of lands and appraisals of damages as they deem necessary. At the completion of the hearing the supervisors shall reestablish the original records or establish a revised record and basis for apportionment of costs and damages as they find equitable and advisable, and may order such repairs or reconstruction as they find to be needed. All cost of such reestablishment or revisions of records, and of the needed repair or reconstruction shall be apportioned in accordance with the basis established.
