Section 5-11-21 - Revenue bonds; fees and chargesA. At any time after the hearing on formation of the district, the district board may hold a hearing on the question of authorizing the district board to issue one or more series of revenue bonds of the district to provide money for any public infrastructure purposes consistent with the general plan.B. If revenue bonds are approved by resolution, the district board may issue and sell revenue bonds of the district.C. The revenue bonds may be sold in a public offering or in a negotiated sale; however, if the bonds are to be sold in a public offering, no revenue bonds may be issued by the district unless the revenue bonds receive one of the four highest investment grade ratings by a nationally recognized bond rating agency.D. The district board may pledge to the payment of its revenue bonds any revenues of the district or revenues to be collected by the municipality or county in trust for the district and returned to the district.E. The district shall prescribe fees and charges, and shall revise them when necessary, to generate revenue sufficient, together with any money from the sources described in Section 17 [5-11-17 NMSA 1978] of the Public Improvement District Act, to pay when due the principal and interest of all revenue bonds for the payment of which revenue has been pledged. The establishment or revision of any rates, fees and charges shall be identified and noticed concurrently with the annual budget process of the district pursuant to Section 23 [5-11-23 NMSA 1978] of the Public Improvement District Act.F. If, in the resolution of the district board, the revenues to be pledged are limited to certain types of revenues, only those types of revenues may be pledged and only those revenues shall be maintained.G. No holder of revenue bonds issued pursuant to the Public Improvement District Act may compel any exercise of the taxing power of the district, municipality or county to pay the bonds or the interest on the bonds. Revenue bonds issued pursuant to that act are not a debt of the district, municipality or county, nor is the payment of revenue bonds enforceable out of any money other than the revenue pledged to the payment of the bonds.H. Subject to the requirements of this section, a district may issue revenue bonds at such times and in such amounts as the district deems appropriate to carry out a project in phases.I. Pursuant to this section, the district may issue and sell refunding bonds to refund revenue bonds of the district authorized by the Public Improvement District Act. Refunding bonds issued pursuant to this section shall have a final maturity date no later than the final maturity date of the bonds being refunded. Laws 2001, ch. 305, § 21.
