N.M. Stat. § 72-20-89
Notwithstanding any limitation or other provision in the Eastern Sandoval County Arroyo Flood Control Act, whenever a majority of the qualified electors of the authority voting on a proposal to issue bonds has authorized the authority to issue bonds for any purpose authorized in that act, the authority is authorized to borrow money without any other election in anticipation of taxes, the proceeds of the bonds or any other revenues of the authority, or any combination thereof, and to issue interim debentures to evidence the amount so borrowed. Interim debentures may mature at such time not exceeding a period of time equal to the estimated time needed to effect the purpose for which the bonds are so authorized to be issued, plus two years, as the board may determine. Except as otherwise provided in this section and in Sections 90 and 91 [72-20-90 and 72-20-91 NMSA 1978] of the Eastern Sandoval County Arroyo Flood Control Act, interim debentures shall be issued as provided in that act for securities in Sections 47 through 80 [72-20-47 to 72-20-80 NMSA 1978] of the Eastern Sandoval County Arroyo Flood Control Act. Taxes, other revenues of the authority, including without limiting the generality of the foregoing proceeds of bonds to be thereafter issued or reissued or bonds issued for the purpose of securing the payment of interim debentures may be pledged for the purpose of securing the payment of the interim debentures. Any bonds pledged as collateral security for the payment of any interim debentures shall mature at such time as the board may determine, but in no event exceeding forty years from the date of either any of such bonds or any of such interim debentures, whichever date is earlier. Any such bonds pledged as collateral security shall not be issued in an aggregate principal amount exceeding the aggregate principal amount of the interim debenture secured by a pledge of such bonds nor shall they bear interest at any time which with any interest accruing at the same time on the interim debenture so secured exceeds six percent per year.
