If the board determines a drain, lateral drain, or ditch has been opened or established by a landowner or tenant contrary to this chapter or any rules adopted by the board, the board shall notify the landowner by registered mail at the landowner’s address of record. A copy of the notice also must be sent to the tenant, if any. The notice must specify the nature and extent of the noncompliance and must state if the drain, lateral drain, or ditch is not closed or filled within the period the board determines, but not less than fifteen days, the board shall procure the closing or filling of the drain, lateral drain, or ditch and assess the cost, or the portion the board determines, against the property of the landowner responsible. The notice also must state the affected landowner, within fifteen days of the date the notice is mailed, may demand in writing a hearing on the matter. Upon receipt of the demand, the board shall set a hearing date within fifteen days from the date the demand is received. In the event of an emergency, the board may apply immediately to the appropriate district court for an injunction prohibiting the landowner or tenant from maintaining the drain, lateral drain, or ditch. Assessments levied under this section must be collected in the same manner as other assessments authorized by this chapter. If, in the opinion of the board, more than one landowner or tenant has been responsible, the costs may be assessed on a pro rata basis in accordance with the proportionate responsibility of the landowners. A landowner aggrieved by action of the board under this section may appeal the decision of the board to the district court of the county in which the land is located in accordance with the procedure provided for in section 28-34-01. A hearing as provided for in this section is not a prerequisite to an appeal.
