In the alternative, a municipality may establish one or more service areas for the collection of development fees. As used in this section, "service area" means a geographic area defined by a municipality in which a defined public infrastructure system provides service to developments within that service area. Service areas shall be carefully drawn so as to include only property locations that are clearly served by the cost of capital improvements that increase or expand the functional service capacity of the public infrastructure system that will be funded through the development fee that is associated with the service area. The determinations regarding the establishment of one or more service areas will be a matter of legislative determination and discretion. Different public infrastructure systems may have different and separately defined service areas unique to each system's coverage. The development fees within a particular service area may be different as applied to different types of land uses; and
All duly enacted ordinances, resolutions, or regulations existing at the time of the effective date of this section shall remain in full force and effect; provided, no existing impact or development fees shall be amended, modified, or renewed except in accordance with this act.
If the municipality determines that the development fees as collected within a service area are no longer needed or desired for the purpose for which they were collected, the municipality may either refund the collected fees to the current owners of the property within the development for which the fees were paid, or proceed through the hearing process as set forth in paragraph 3 of subsection C of this section in order to adopt a new purpose for the fees.
