Such funds shall be used for the purpose of paying the costs of operation, capital improvements, construction, reconstruction, repair and maintenance of the storm water facilities of the City and to carry out all other purposes of this utility. To the extent that the Storm Water Utility fees collected are insufficient to construct the needed storm water drainage facilities, the costs of same may be paid from such City funds as may be determined by the City Commission, but the City may order reimbursement of such fund if additional6 fees are thereafter collected. When the fund has surplus dollars on hand in excess of current needs, the surplus dollars shall be invested to return the highest yield consistent with proper safeguards. Any interest earned on invested funds, bond revenues, and other revenues shall be placed in the Storm Water Utility fund.

(b)   Storm Water Utility fees and charges paid and other revenue received shall not be used for general or other governmental or proprietary purposed of the City.
