Funds collected by state colleges and universities for parking permits, including any unexpended balances on hand on June 30 of each year, may be reserved and retained indefinitely for use only for future construction and repair and maintenance of parking facilities, including streets, roadways, walks, and walkways leading into such parking facilities and for operation of these parking programs and for all operations incidental to campus related parking; however, no funds appropriated from the state general fund for operating expenses may be expended for construction, repair, or maintenance of parking facilities until all proceeds from such parking permits have been expended.
