(a) The opening and restoration of pavement or other surfaces shall be performed under the supervision and to the satisfaction of the Director of Public Service and in accordance with current rules, regulations, and specifications on file in the Office of the Director of Public Service.
(b) Upon failure or refusal of the permittee to satisfactorily restore the subsurface and surface of the pavement or remove all excess materials within the time specified in the permit or, where not specified, in a reasonable amount of time after commencement of work, the City may restore the subsurface and surface without notice to the permittee. In that event, the deposit referred to in Section 903.03 shall be deemed forfeited. Such deposit shall be paid into the appropriate fund of the City, except that part in excess of the actual cost to be incurred by the City to restore the site in the manner established by the permit utilizing either City personnel and equipment, or otherwise as the City deems appropriate. If the cost of restoration performed by the City or its agent should exceed the amount of such deposit, the Director of Public Service shall collect the balance due from such permittee.
