907.13 RESTORATION BY DIRECTOR OF PUBLIC WORKS.
   The Director of Public Works shall, as soon as practicable after any excavation has been made in any street, thoroughfare, park or public ground, restore the pavement or other surfacing thereon, unless in the case of another City department or other person properly equipped and competent to do so, he shall authorize such restoration to be made by the person making the excavation. When the pavement or other surfacing is restored to the Director's satisfaction, he shall determine the cost to the City of such restoration, including the cost of all inspections, of all backfilling done by the City, of all labor and material expended in repairing or resurfacing, and a reasonable charge for overhead services, and shall certify such cost to the Director of Finance, who shall thereupon issue a receiving warrant or voucher, to transfer to the General Fund so much of the deposit made in respect of such improvement as may be necessary to defray the cost so certified, and shall return any balance in such deposit to the depositor. If the cost so certified exceeds the amount deposited, the Director of Finance shall proceed forthwith to collect the remainder due the City. (1931 Code §27.3382)
