Iowa Code § 6A.20: Description of land furnished.

Whenever any person, state department, or political subdivision takes title to land in fee simple for a public use by condemnation or by purchase in lieu of condemnation, the purchaser shall furnish to the owner of the land a legal description of the part taken and a legal description of the remainder which is compatible with the existing abstract description of the entire tract of land. For the purposes of this section a center line description is compatible only when it contains reference points which are a part of and tied to the abstract description.
