(A)   The opening and restoration of a pavement or other surface shall be performed under the direction and to the satisfaction of the authorized city official, and in accordance with rules, regulations, and specifications approved by the legislative body.
   (B)   Upon failure or refusal of the permittee satisfactorily to fill the excavation, restore the surface, and remove all excess materials within the time specified in the permit or where not specified therein, within a reasonable time after commencement of the work, the city may proceed without notice to make such fill and restoration and the deposit referred to in § 91.02 shall be forfeited. Thereupon the deposit shall be paid into the appropriate city fund, except such part demanded and paid to the permittee as the difference between the deposit and the charges of the city for restoration services performed by it. If the amount of such services performed by the city should exceed the amount of the deposit, the Clerk or other proper administrative officer shall proceed to collect the remainder due from the permittee.
