If, in his judgment, traffic conditions, safety or convenience of the traveling public or the public interest require that excavation work be performed speedily, the city manager may, at the time the permit is granted, require that a crew of men and adequate tools and equipment be employed by the applicant twenty four (24) hours a day to complete the excavation work as soon as possible. If the applicant fails in this requirement, the city manager may complete the work with city crews at applicant's cost and shall ban applicant's engaging in trenching or excavation work in the city until the costs are paid. Work may not be declared urgent unless there is considerable public inconvenience such as a street blocked to all traffic that is normally well traveled or is the only public access to an adjoining area.
