(A)   The location of all existing utilities shall be determined in advance of any excavation by the permit holder and the necessary precautions shall be taken to safeguard against damage during the execution of excavation work.  The cost of repairing any damage to pipes, driveways, culverts, or any other facilities due to any excavation activity shall be borne by the permit holder.
   (B)   Any permit holder who finds it necessary to block or cause to be blocked any public right-of-way traveled by pedestrians or motor vehicle traffic, shall maintain sufficient barricades, warning signs, and lights to warn and protect those using the public right-of-way during the entire period of excavation.  If the excavation occurs on a portion of a public right-of-way traveled by motor vehicles, devices shall be placed, for main arterial streets, at least 100 yards; and if a residential street, at least 50 yards.  During the night hours, self-illuminating warning devices shall be required on any right-of-way traveled by motor vehicles and pedestrians.
   (C)   The holder of an excavation permit shall be responsible for providing steel plates necessary to cover excavations so as to maintain motor vehicle and pedestrian flows during the course of construction.
