Special assessment bonds.

A. A district may issue one or more series of bonds to provide money for renewable energy improvements to property in the district, and the bonds may be payable from the special assessments levied pursuant to one or more assessment resolutions. B. For any bonds issued pursuant to the Renewable Energy Financing District Act, the district board shall prescribe the denominations of the bonds, the principal amount of each issue and the form of the bonds and shall establish the maturities, which shall not exceed twenty years, interest payment dates and interest rates, whether fixed or variable, not exceeding the maximum rate stated in the resolution of the district board. The bonds may be sold by competitive bid or negotiated sale for public or private offering at, below or above par. The proceeds of the bonds shall be deposited with the treasurer, or with a trustee or agent designated by the district board, to the credit of the district to be withdrawn for the purposes provided by the Renewable Energy Financing District Act. Pending that use, the proceeds may be invested as determined by the district. The bonds shall be made payable as to both principal and interest solely from revenues of the district, and shall specify the revenues pledged for such purposes, and shall contain such other terms, conditions, covenants and agreements as the district board deems proper. C. No holder of special assessment bonds issued pursuant to the Renewable Energy Financing 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. Special assessment bonds issued pursuant to that act are not a debt or general obligation of the county or the municipality in which the district is located, nor is the payment of special assessment bonds enforceable out of any money other than the revenue pledged to the payment of the bonds. D. Pursuant to this section, the district may issue and sell refunding bonds to refund any special assessment bonds of the district authorized by the Renewable Energy Financing 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.
