The charges imposed for services rendered by means of a county service area shall not exceed the reasonable estimated cost of providing the service. The charges may be determined by apportioning the total cost, not otherwise offset by other available revenue, of the services provided within the county service, or any zone thereof, to each parcel therein in proportion to the estimated benefits from the service to be received by each parcel based upon the land use classification of the parcel. The charges may be fixed on an annual basis or may vary by reason of the nature or use of the service so that the charges correspond to the cost and the value or benefit of the service.
