(A) The Board of Public Works and Safety deems it necessary to establish a firm policy for the backfilling of excavation and replacement of pavement disturbed as a result of making an opening or excavation in any street, these specifications are set forth and the compliance herewith shall be a requirement of obtaining a permit for the opening or excavation as set forth in the city code. It shall be the obligation of any person, firm or corporation obtaining a permit for an opening or excavation in the public right-of-way to backfill the excavation and replace the pavement as set forth in these specifications. Deviations from these specifications shall only be made upon approval by the City Engineer.
(B) All excavations under pavement shall be backfilled with a reasonably clean granular material with good compact qualities. The materials shall be placed in layers not to exceed six inches in depth. Each layer shall be thoroughly tamped with a vibratory type mechanical tamper. Special care shall be taken in filling around sewers, water pipes, gas lines and the like, to the earth at the same height on both sides to avoid shirting of the pipe line. No removed paving materials or debris shall be used in backfilling the excavation. Excavations not under a pavement may be backfilled with virgin material removed from the excavation, by approval of the Board of Public Works or its designated representative.
