(b) In lieu of payment by the parkways authority of county property taxes and other assessments on restaurant and gas service facilities owned by it, or upon any facility described in subsection (b) of section thirteen herein which is leased to any private person, corporation, or entity, the parkways authority shall make an annual payment as provided herein to the county commission of such county. Any parkways authority project which is leased and is exempt from taxation shall be subject to a payment in lieu of taxes. Said payment shall be made to the county commission of the county in which the project is located and shall be in an amount equal to the property taxes otherwise payable. The county commission receiving such in lieu of payment shall distribute such payment to the different levying bodies in that county in the same manner as are property taxes. Nothing contained herein may be construed to prohibit the parkways authority from collecting such in lieu payment from any private party by contract or otherwise.
