The council may also issue combined tax and revenue bonds if deemed advisable, or pledge any other security permitted by law to the payment of such revenue bonds in addition to such revenues from such utility or other revenue producing enterprise or facility; provided, however, that if ad valorem taxes are pledged for the payment of all or any part of bonds for which such revenues are also pledged, the provision for a referendum on petition on issuance of tax bonds provided herein shall apply to such revenue bonds for which ad valorem taxes are also pledged.
