The city council of a city of the metropolitan class shall make all necessary rules and regulations governing the use, operation, and control of facilities authorized by sections 14-1731 to 14-1740. In the exercise of the grant of power set forth in sections 14-1731 to 14-1740, the city of the metropolitan class shall make contracts with others, if such contracts are necessary and needed for the payment of the revenue bonds authorized in sections 14-1731 to 14-1740 and for the successful operation of the parking facilities.
