Notwithstanding the provisions of this chapter, overhead facilities may be installed and maintained for a period, not to exceed ten (10) days, without authority of the public works director in order to provide emergency service. The public works director may grant special permission, on such terms as he 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.
