No person shall be allowed to make any excavation in any paved street or alley, or remove any paving or other material forming any street or alley improvement, without a permit from the Municipal Services Director, to be issued only upon the written application of the party desiring such permit. Such person shall maintain good and sufficient barricades, guards, lights and signals to protect the public from injury or loss. When required such applicant shall deposit with the City Clerk a sum sufficient to cover the cost of replacing any improvement so removed, and the Municipal Services Director and City Engineer shall cause such pavement to be replaced. After paying the expense thereof out of such deposit, the balance of the deposit remaining in the hands of the City Clerk, if any, shall be refunded to the applicant. When a deposit is not required the City Clerk shall cause to be collected the cost of said replacement from the applicant. All such cuts or excavations shall be made under the supervision of the City Engineer or the Municipal Services Director.
