Except as otherwise provided, these rates, fees and charges, including, in the case of parking facility rates, fees and charges for parking on the public ways or in the public parking areas included in the parking system designated by the municipal officers of which the parking facility is a part, shall be fixed and revised to provide funds which, together with all other funds available for the purpose, will be sufficient at all times to pay the cost of maintaining, repairing and operating the revenue-producing municipal facility and parking system, including reserves for those purposes, and to pay the principal of and interest on the revenue bonds, as the same becomes due and payable, and reserves for that purpose. The rates, fees and charges must be reasonable, just and equitable.

In fixing or revising reasonable, just and equitable rates, fees and charges under subsection 1 or under section 3009, subsection 1, paragraph C, when adequate parking facilities for the accommodation of traffic have been provided and paid for, the rates, fees and charges shall be adjusted to provide funds for maintenance and operation only.
