It shall be the duty of every person making an excavation in or upon any public place, to place and maintain barriers and warning devices necessary for the safety of the general public. Barriers, warning signs, lights and the like shall conform to the requirements of all applicable city ordinances. Warning lights shall be flares, torches, lanterns, electrical markers or flashers used to indicate a hazard to traffic from sunset of each day to sunrise of the next day. Torches shall be open wick or flame flares or bombs generally used in connection with roadway repairs or construction and operating on kerosene or similar fluid. Electrical markers or flashers shall emit light at sufficient intensity and frequency to be visible at a reasonable distance for safety. Reflectors or reflecting material may be used to supplement, but not replace, light sources. The City Building Inspector shall determine whether or not lighting is sufficient under the terms of this chapter. The applicant shall take appropriate measures to assure that during the performance of the excavation work, traffic conditions as near as normal as possible shall be maintained at all times so as to minimize inconvenience to the occupants of the adjoining property and to the general public. When traffic conditions permit, the City Manager may by written approval permit the closing of streets and alleys to all traffic for a period of time prescribed by him or her, if in his or her opinion it is necessary. Written approval may require that the permittee give notification to various public agencies and to the general public. In these cases, the written approval shall not be valid until notice is given.
