The county board shall, within sixty days of receipt of the request, approve or deny the request for withdrawal. At any time after six years from the date of creation of an agricultural area, an owner may withdraw from an agricultural area by filing with the county board a notice of withdrawal containing a legal description of the land to be withdrawn.2. The board shall cause the description of that agricultural area filed with the county auditor and recording officer in the county to be modified to reflect any withdrawal. Withdrawal shall be effective on the date of recording.
