Notwithstanding any other provision of law, an annual administrative fee may be charged for the administration of a special service area. Such annual administrative fee may be derived from the annual tax levy for each special service area. Any amount recommended by a special service area commission and approved as an administrative expense which may be paid to the service provider agency pursuant to the budget included in a services contract shall not exceed 30% of the annual tax levy for the special service area that is the subject of such services contract and is separate from any municipal administrative fee.
