(1) An application for permit shall be filed in duplicate in the office of the City Engineer on such forms as are specified by the City Engineer and shall be accompanied by a detailed plan, specifications and profiles of such size and such scale as may be prescribed by the City Engineer of pipes or mains and fixtures to be laid or installed underneath public properties, which shall show the centerline of the street or alley, and in relation thereto the position, location and depth of the distribution system, the height of the proposed work, the pipes or mains intended to be laid, the size of the pipes or mains, the location of the manholes leading to the pipes or mains if any, and the depth of the pipes or mains from the surface and such other information as he may require. The permittee, its successors and assigns shall amend the plans, specifications and profiles in accordance with the orders of the City Engineer before the City issues the permit and before the permittee commences construction or the laying of the pipes or mains, or the construction of any overhead utility service. The permittee shall advise the City Engineer in writing of the plan of the excavation, obstruction or other thing desired to be done or constructed, the size thereof, the purpose therefor, and the public property so to be excavated and/or obstructed, together with a full description of the nature of such work, and the name of the person, firm or corporation for whom or which the work is being done. Whenever additional improvements or extensions are made, additional plans, specifications and profiles shall be filed with the City in the same manner as required above. The application shall contain an agreement that the applicant will comply with all ordinances and laws relating to the work to be done and that no openings shall be made or obstruction erected until necessary fittings and materials are available and on hand to complete the work.

(2) Each application for a permit shall state the length of time it is estimated will elapse from the commencement of the work until the restoration of the surface of the ground or until the refill is made ready for the surface to be put on by the City if the City restores such surface. It is unlawful to fail to comply with this time limitation unless permission for an extension of time is granted by the City Engineer. If an extension of time is needed to complete the work beyond the time originally prescribed, a new application for a permit must be filed, and when the application therefor is signed by the City Engineer, it shall constitute the permit; provided, that the bond and insurance are extended for the period of the extension granted.
