Iowa Code § 464A.6: Filing appraisement.

The appraisers appointed to determine the damages caused by the proposed project shall view the premises and determine and fix the amount of damages to which each claimant is entitled and shall, at least three days before the date fixed by the commission to hear and determine the same, file with the secretary of the commission reports in writing showing the amount of damages sustained by each claimant. Should good cause for delay exist, the commission may postpone the time of final action on the project.
