Mo. Rev. Stat. § 393.100

In case the property sought to be appropriated is held by any corporation, the right to appropriate the same for the purposes aforesaid by any corporation, company or individual shall be limited to such use as shall not materially interfere with the uses to which by law the corporation holding the same is authorized to put said property. Where no agreement can be made between the parties, the mode of assessing the damages provided heretofore as to private persons shall be adopted, and if the property to be appropriated lies in more than one county, an application may be made in any one county in which any of the lands lie, and the damages shall be assessed as to all the lands of the defendant corporation along the whole line in one proceeding.
