If upon expiration of the thirty (30) day period the said required underground facilities have not been provided, the City Engineer shall forthwith proceed to do the work with his own force or may let a contract for the work, provided however, if such premises are unoccupied and no electric or communications services are being furnished thereto, the City Engineer shall in lieu of providing the required underground facilities, have the authority to order the disconnection and removal of any and all overhead service wires and associated facilities supplying utility service to said property. Upon completion of the work by the City Engineer, the City Engineer shall file a written report with the City Council setting forth the fact that the required underground facilities have been provided and the cost thereof, together with a legal description of the property against which such cost is to be assessed. The City Council shall thereupon fix a time and place for hearing protests against the assessment of the cost of such work upon such premises, which said time shall not be less than ten (10) days thereafter.
