(A) It is unlawful for anyone, in any manner to obstruct, excavate or tear up any public place, without at all times during the performance of the work providing and maintaining such fences, barricades, red lights, flares, warning and directional signals, flagmen and watchmen as are necessary for the safety of the general public. All barricades, fences, warning and directional signs shall be illuminated from one-half hour before sunset to one-half four after sunrise. “No parking” signs shall be placed the evening prior to commencement of work and shall be equally spaced at the rate of four per block each side of the street. Lettering on signs shall be three inches high. The sign shall show hours of the day in which parking is restricted. Barricades may be removed at the completion of work or the removal of obstructions in public places providing the surface of the roadway has been restored to the satisfaction of the Director of Public Works.
(B) The contractor, municipal department, or utility company will provide and maintain all necessary lighting devices (torches, lanterns, flashers, and electric lights) throughout the period when a street or other public place is used, and will be responsible for providing and maintaining any necessary warning signs and barricades adjacent to the construction or work area. In the event that a city crew must be called to perform any maintenance on any lighting devices, or other means of protecting the public due to the failure of the contractor to comply with this regulation, a service call fee of fifty dollars per location will be billed to the responsible private firm or individual by the city. No payments on any contract with the city will be made until all such fees are paid in full.
