A. No trench shall be opened in any street for the purpose of laying pipes, conduits or ducts more than four hundred (400) feet in advance of the pipe, conduit or ducts being placed in the trench, except when the prior written consent of the director has been obtained.
B. All excavations shall comply with the standards and requirements established from time to time by the director for compaction, backfill and pavement restoration. The standards and requirements may vary for different excavations, taking into consideration relevant factors, such as: (1) the location, type and extent of excavation performed, (2) the condition of the surface being excavated, and (3) the period of time elapsed since the construction or most recent resurfacing of the surface being excavated. The standards and requirements shall be reviewed at least once every five years to determine whether any changes can be made to prevent or substantially reduce the degradation and damage caused to the street surface by excavation. As part of such review, the director shall provide affected utility companies with an opportunity to review and comment upon the standards and requirements and any changes proposed thereto.
C. The excavated pavement and other rubble shall be removed, together with any surplus excavated material, within one working day from the time such material is placed upon the street, provided that exceptions to this requirement may be approved by the director. After backfilling is completed, and prior to repaving the cut, the contractor or permittee shall remove all loose paving material and trim the edges of the excavation at the street surface to the satisfaction of the director.
D. Whenever any caving occurs in the sidewalls of any excavation, the pavements above such caving shall be cut away. In no case shall any void under a pavement be filled by any side or lateral tamping. (Ord. 2009-022 § 2)
