Neb. Rev. Stat. § 3-331

In any case in which (1) it is desired to remove, lower, or otherwise terminate a nonconforming structure or use, (2) the approach protection necessary cannot, because of constitutional limitations, be provided by airport zoning regulations under the Airport Zoning Act, or (3) it appears advisable that the necessary approach protection be provided by acquisition of property rights rather than by airport zoning regulations, the political subdivision within which the property or nonconforming use is located or the political subdivision owning or operating the airport or served by it may acquire by purchase, grant, or condemnation, such air right, aviation easement, or other estate or interest in the property or nonconforming structure or use in question as may be necessary to effectuate the purposes of the act. The procedure to condemn property shall be exercised in the manner set forth in sections 76-704 to 76-724 .
