A. Restoration Of Street Surface: After the completing of the laying of any pipe, line or conduit, or the installation or repair of any facility for which the excavation was undertaken, the excavator shall cause the work to be backfilled in such a manner as to make the street in as good a condition as before the excavation.
B. Maintenance: Any person making any excavation in any street or alley, as set forth in this chapter, shall be fully responsible for the maintenance of the excavation for a period of six (6) months after the backfill thereof. If any settlement occurs in the area that was formerly excavated, the excavator or person causing the excavation shall immediately upon notice fill in the settling and put the street, alley, or avenue, in as good a condition as possible for use by the public.
