In the event that the surety (or principal), within a reasonable time following the giving of such notice (taking into consideration the exigencies of the situation, the nature of the work, and the requirements of public safety and for the protection of persons and property), fails either to commence and cause the required work to be performed with due diligence, or to indemnify the city for the cost of doing the work, as set forth in the notice, the city may perform the work, at the discretion of the city engineer, with city forces or contract forces or both, and suit may be commenced by the city attorney against the contractor and bonding company and such other persons as may be liable, to recover the entire amount due to the city, including attorney fees, on account thereof. In the event that cash has been deposited, the costs of performing the work may be charged against the amount deposited, and suit brought for the balance due, if any. (Ord. 70-99 § 1, 1999)
