Fences

1. A fence which constitutes an immediate and dangerous hazard shall, without notice or liability in damages, be removed by the highway authority. In all other cases where a fence is an obstruction in a highway right-of-way, notice in writing of not less than thirty days shall be given to the owner, occupant, or agent of the land enclosed by the fence. 2. The notice shall, with reasonable certainty, specify the line to which the fences shall be removed and shall be served in the same manner that original notices are required to be served, or in writing by certified mail, or in any other manner reasonably calculated to apprise the person responsible for the fence. 3. The department and the county engineer, or the board of supervisors if a county engineer is not available, may designate the location of a fence within a highway right-of-way. A fence that is not properly located within the highway right-of-way shall be removed within a time prescribed to a designated location. If not so removed, the highway authority may remove the fences and recover costs as provided in section 318.5.
