Notwithstanding the provisions of this chapter, overhead facilities may be installed and maintained for a period not to exceed ten days, without authority of the council, in order to provide emergency service. The council may grant special permission on such terms as the council may deem appropriate, in cases of unusual circumstances, without discrimination as to any person or utility, to erect, construct, install, maintain, use or operate poles, overhead wires and associated overhead structures. (Ord. 893 NCS §1; prior code § 10.5.)
