Wis. Stat. § 32.21
Whenever any lands or interest therein are urgently needed by any state board, or commission, or other agency of the state, and a contract for the purchase or use of the property cannot be made for a reasonable price, or for any other reason, including the unavailability of the owner or owners, the board, commission or agency may, with the approval of the governor, issue an award of damages and upon tender of the award to the owner or owners, or deposit in a court of record in the county where the lands are situated in cases where an owner is not available or tender is refused, take immediate possession of said property. Deposit in a court of record may be made by registered mail addressed to the clerk of the court. The governor shall determine whether or not such an award shall issue. Appeal from said award of damages will lie as in other similar cases and all provisions of this subchapter shall govern, except as to the provision herein concerning the immediate issuance of the award tender and immediate possession.
