Such bonds may be additionally secured by municipal bond insurance, bank guarantees, surety bonds, letters of credit and other devices to enhance the credit quality of the bonds, the cost of which credit enhancement devices may be paid from the proceeds of the bonds or such other funds as may be available. Bonds issued hereunder to refund bonds shall be issued in accordance with the provisions of Chapter 14-A of Title 39 of the Louisiana Revised Statutes, and for the purposes thereof, the Sewerage and Water Board of New Orleans shall be deemed to be the governing authority of the issuer whenever such term is used in said Chapter; provided, however, the Board of Liquidation, City Debt, shall fix the details of the bonds and sell the bonds as provided in R.S. 33:4100 and R.S. 33:4101, respectively. The resolution of the Sewerage and Water Board of New Orleans authorizing the issuance of such bonds shall not be effective until approved by a resolution adopted by affirmative vote of two-thirds of the members of the council of the city of New Orleans and by a resolution adopted by affirmative vote of a majority of the members of the Board of Liquidation, City Debt. All bonds issued pursuant to this Section shall be excluded in applying any limitation upon the power of the city of New Orleans to issue bonds for any purpose. No bonds shall be issued under this Section which, when added to the bonds previously issued hereunder and then outstanding, would make the total of such bonds outstanding exceed twelve million dollars. For the purpose of calculating said debt limitation, there shall be included the amount of any refunding bonds and there shall be excluded the amount of those issues of bonds refunded by the refunding bonds.
