Notwithstanding any other provision of law, a county may, by ordinance, agree to provide emergency ambulance service to any portion of a fire protection district that the county is already providing emergency ambulance service through an intergovernmental agreement. The ordinance to provide emergency ambulance service under this Section must contain an affirmative obligation on the part of the county to provide emergency ambulance service to the fire protection district once the intergovernmental agreement in effect at the time of the ordinance expires.
An ordinance adopted under this Section does not take effect until after the fire protection district adopts a resolution under Section 22.1 of the Fire Protection District Act to discontinue the emergency ambulance service and the intergovernmental agreement for emergency ambulance service between the county and the fire protection district has ended. Upon certification to the county clerk by both the county and the fire protection district that all criteria have been met under this Section and Section 22.1 of the Fire Protection District Act, the tax rate for emergency ambulance service for the area once serviced under the fire protection district for emergency ambulance service shall be the rate the county levies under Section 5-1028.
