The city engineer will review all such plans and specifications and may require revisions therein to comply with applicable laws and ordinances and with generally accepted engineering principles and practices applied on a uniform basis throughout the city. After completion of revisions, if any, required by the city engineer, he or she may require that the estimate of costs of such public improvements be increased or decreased to reflect such revisions and shall approve such cost estimate in writing. In the event of any increase to such cost estimate, the owner shall cause to be paid to the city collector the amount of any increase in the review and inspection fee computed under the foregoing table. After approval by the city engineer of such plans, specifications and cost estimate, the owner shall submit to the city administrator's office a cash security deposit or an escrow (with an escrowee approved by the city council) of cash funds or United States government securities, in an amount determined by the city engineer to be sufficient to cover the cost of all public improvements required within such subdivision, but not in excess of one and one-half (11/2) times the amount of such cost estimate; provided, that any such escrow agreement shall contain an express provision to the effect that upon expiration of two (2) years from the recording of the final plat of subdivision or, with respect to sidewalks, upon expiration of such shorter period as may be specified under the provisions of section 9-4-1-3 of this chapter, the escrow funds or any portion thereof may be withdrawn upon the determination and direction of the mayor and the city treasurer and disbursed to the treasurer, to be held and used only for the payments of the cost of such public improvements or any portion thereof; and provided further, that in any case in which the amount of such required security deposit or escrow exceeds one hundred thousand dollars ($100,000.00), such owner may furnish to the city administrator, in lieu of any amount up to sixty six and two-thirds percent (662/3%) of the amount of such excess, a performance bond, with surety or sureties and in an amount approved by the city engineer, guaranteeing completion of all such public improvements. The city may use all or any portion of such security deposit, or may take appropriate action to enforce such performance bond, in the event that all such public improvements have not been completed within two (2) years after the recording of the final plat of subdivision or, with respect to sidewalks, within such shorter period as may be specified in section 9-4-1-3 of this chapter. In the event the mayor and treasurer cannot agree upon whether or how much to withdraw, the issue shall be brought before the city council who shall decide. (Ord. 99-40-0, 8-25-1999)
