Notwithstanding any provisions in this Part 3 to the contrary, the city may issue and sell development revenue bonds at public or private sale for the public purposes of promoting industry and developing trade or other economic activity in such manner as provided by state statute. Said bonds shall not constitute a general obligation of the city and shall be payable solely out of the revenues derived from the financing, sale or leasing of the project with respect to which the bonds are issued.
