All fees collected by the City, including the pedestrian-scale street light fee, and such other moneys as might be available to the City for the purposes of this ordinance shall be paid into the Street Utility Fund. Such revenues shall be used for the purposes of the operation and maintenance of the street network of the City. It shall not be necessary that the operations and maintenance expenditures from the Fund specifically relate to any particular property from which the fees for said purposes were collected. To the extent that the fees collected are insufficient to properly operate and maintain streets, the cost of the same may be paid from such other City funds as may be determined by the City Council, but the City Council may order the reimbursement to such fund if additional fees are thereafter collected. All amounts on hand in the Street Utility Fund shall be invested by the Chief Financial Officer in investments proper for City funds. The fees paid and collected by virtue of this ordinance shall not be used for general or other governmental or proprietary purposes of the City, except to pay for the equitable share of the cost of accounting, management and government which is attributable to the Fund, which shall not exceed 5% of the gross revenues of the Fund during any fiscal year. Other than as described above, the fees and charges shall be used solely to pay for the cost of operation, administration, maintenance, repair, improvement, renewal, replacement and reconstruction of the streets of the City and costs incidental thereto.
