§ 97.050  AUTHORITY TO ENFORCE.
   The Director of the Department of Public Services is responsible for the proper enforcement of this subchapter and may seek advice from the City Engineer and call upon the Police Department for police action if needed.
   (A)   All work shall be pursued diligently and continuously until the project is completed. When as a consequence of the weather or any legal proceedings, or any other unexpected contingency, the project is not continuing as required by this subchapter, the excavation or opening shall be filled by direction of the Director as if the work contemplated were finished.
   (B)   A project shall not involve a larger area than is requested in the permit application, and if such be necessary permission must be obtained by the director of public works and noted on the permit.
   (C)   All work shall be performed in such a way as to cause a minimum of inconvenience and restriction to both pedestrian and vehicular traffic.
   (D)   The recipient of a permit shall notify all utility companies whose pipes, poles, mains or conduits are to be disturbed by the excavation at least 24 hours before commencing of any work.
   (E)   The width of such excavation or opening shall be only such as is required to do the work properly. Good construction practices shall prevail in all operations, including the requirements for bracing, shoring, tunneling, and the like.  All excavating is to be done by the open cut method, unless special permission is granted by the Director and so noted on the permit.
   (F)   All refilling must be done within the specified time granted by the permit, and shall consist of sand, gravel or other materials of equivalent compaction qualities. The crown of the pavement or unimproved street must be restored by the permit holder.
   (G)   If, in the opinion of the Director of the Department of Public Services, the procedures employed or materials used by the permit holder in the backfilling are not satisfactory, the Director shall have the same done by the city. All costs and charges paid out by the city shall be deducted by the City Treasurer before bond is released.
