If conditions are such that street lights cannot be installed prior to the acceptance of the streets upon which the street lights are to be installed as required in Section 1109.16, the person, firm or corporation requesting acceptance of such streets shall deposit with the Director of Finance an amount of cash or a performance bond in form satisfactory to the Law Director, equal to one and one-half times the estimated cost of the installation of street lights as security for the installation of such lights, which installation shall be completed within six months of the date of deposit of such funds or bond. Failure on the part of such person, firm or corporation to complete the installation within six months shall be cause for the Manager to order installation by such other contractor as he may choose and cause the cost of installation to be paid from the funds or bonds so deposited. That portion of such funds not used for the installation shall be returned to the depositor at the completion and acceptance by the Village of the street lighting installation.
