Iowa Code § 28J.27

(1) When a port authority changes the location of any portion of any public road, railroad, or utility facility in connection with the construction of a port authority facility, the port authority shall reconstruct at such location as the governmental agency having jurisdiction over such road, railroad, or utility facility finds most favorable. The construction of such road, railroad, or utility facility shall be of substantially the same type and in as good condition as the original road, railroad, or utility facility. The cost of such reconstruction, relocation, or removal and any damage incurred in changing the location of any such road, railroad, or utility facility shall be paid by the port authority as a part of the cost of the port authority facility.

(2) When the port authority finds it necessary that a public highway or portion of a public highway be vacated by reason of the acquisition or construction of a port authority facility, the port authority may request the director of transportation to vacate such highway or portion in accordance with chapter 306 if the highway or portion to be vacated is on the state highway system, or if the highway or portion to be vacated is under the jurisdiction of a county, the port authority shall petition the board of supervisors of that county, in the manner provided in chapter 306, to vacate such highway or portion. The port authority shall pay to the county, as a part of the cost of such port authority facility, any amounts required to be deposited with a court in connection with proceedings for the determination of compensation and damages and all amounts of compensation and damages finally determined to be payable as a result of such vacation.

(3) The port authority may adopt bylaws for the installation, construction, maintenance, repair, renewal, relocation, and removal of railroad or utility facilities in, on, over, or under any port authority facility. Whenever the port authority determines that it is necessary that any such facility installed or constructed in, on, over, or under property of the port authority pursuant to such bylaws be relocated, the utility company owning or operating such facility shall relocate or remove them in accordance with the order of the port authority. The cost and expenses of such relocation or removal, including the cost of installing such facility in a new location, the cost of any lands, or any rights or interests in lands, and any other rights, acquired to accomplish such relocation or removal, shall be paid by the port authority as a part of the cost of the port authority facility. In case of any such relocation or removal of such facilities, the railroad or utility company owning or operating them, its successors, or assigns may maintain and operate such facilities, with the necessary appurtenances, in the new location in, on, over, or under the property of the port authority for as long a period and upon the same terms as the railroad or utility company had the right to maintain and operate such facilities in their former location.
