If the board shall determine by resolution that the expenditure of the whole or any portion of the said principal sum of any issue of bonds for the purpose for which such bonds were issued is impracticable or unwise, the board may— (1) Apply such money or any part thereof to the purchase of bonds of that issue, or to the payment of any such bonds, at maturity or on redemption, or to the payment of interest thereon or of premiums due on the redemption thereof; or (2) Apply such money or any part thereof to any new purpose which is within the purposes for which bonds might be issued under the terms of this chapter; provided, however, that before applying any of such money to such new purpose the board shall adopt a resolution specifying such new purpose, the amount of such money to be applied thereto, and authorizing such application, which resolution shall be subject to the same procedures, and take final effect only in the same manner, as if it were a resolution adopted pursuant to Section 13091, authorizing the issuance of bonds for such new purpose, and such resolution authorizing such application to such new purpose, when it shall have taken final effect under such procedures, shall be sufficient authority for the application of such money to such new purpose.
