13.16.210: CARE OF EXCAVATED MATERIAL:
   A.   All material excavated from trenches and piled adjacent to the trench, or in highways, shall be piled and maintained in such a manner that the toe of the slope of the excavated material is at least eighteen inches (18") from the edge of the trench. When the confines of the area through which the gas pipes are to be laid are too narrow to permit the piling of excavated material beside the trench, the permittee may be required to haul excavated material to a storage site and then rehaul it to the trench site at the time of backfilling.
   B.   It shall be the permittee's responsibility to secure the necessary permission and make all necessary arrangements for all storage and disposal sites required. (Ord. 157 § 620, 1961)
