Notice of the designation of such an emergency repair zone shall be given to the adjacent property owners in the best possible manner under the circumstances. If the emergency is such that notice and hearing are impossible, the City may proceed with the emergency repairs and shall consider the impossibility or difficulty of giving advance notice in assessing the costs. Where possible, notice will be given in writing to affected property owners who will have an opportunity for hearing before the Council, before the City Manager, or before the Public Works Director, prior to such emergency repairs.
