(e) Final Plat; Improvement and Cash Bonds; Certificate of Title. After the completion of all required improvements, in accordance with the standards and specifications of the City pertaining to such improvements and to the satisfaction of the Engineer, the subdivider shall file with the Director of Finance an original tracing of waterproof ink on tracing cloth, together with three blueprints of the final plat, meeting the requirements stipulated in Section 1105.05. In lieu of completing the required improvements, the subdivider may execute and file with the Director of Finance an agreement and bond in the amount determined by the Engineer, in form satisfactory to the Director of Law, equal to the approximate total cost of such improvements, which shall insure the City that the improvements will be completed within two years after a final approval of the plat. The subdivider shall also execute and file with the Director of Finance an agreement and maintenance bond in an amount determined by the Engineer, in form satisfactory to the Director of Law, which will insure the City that the improvements will be properly maintained for a period of two years after their completion. If the subdivider elects to file an improvement bond and the construction of dwellings or other structures is commenced, making it necessary that a means of ingress and egress be provided over streets in the subdivision, the subdivider shall improve the street prior to the approval of the final plat to the extent necessary, in the opinion of the Engineer, to provide satisfactory access to dwellings and structures on the street until such time as the street is fully improved in accordance with the terms of the improvement bond. To insure that all streets are properly maintained to provide access, the subdivider will deposit a cash bond with the Director of Finance, in an amount deemed necessary by the Engineer, from which all maintenance costs will be paid until the street is fully improved and the two-year maintenance bond is filed. The subdivider may use the cash bond or any portion of it from time to time to pay for all maintenance expenses, but if he should fail to maintain the street properly, upon request of the Engineer, the City may use such bond to perform necessary maintenance upon giving the subdivider forty-eight hours notice of its intention to do so. The final plat shall be accompanied by a certificate of title showing that the ownership of all lands to be dedicated to public use is free and unencumbered. The final plat shall be filed with the Director of Finance at least twenty days prior to the meeting of the Commission at which action is desired.
