67-11-303. Bonds and obligations. (1) An authority may borrow money for any of its corporate purposes and issue its bonds for those purposes, including refunding bonds, in the form and upon the terms that it may determine, payable out of any revenue of the authority, including revenue derived from:

(a) an airport or air navigation facility or facilities;

(b) taxes levied pursuant to 67-11-301 or other law for airport purposes;

(c) grants or contributions from the federal government; or

(d) other sources.

(2) The bonds may be issued by resolution of the authority, without an election and without any limitation of amount, except that bonds may not be issued at any time if the total amount of principal and interest to become due in any year on the bonds and on any then-outstanding bonds for which revenue from the same source or sources is pledged exceeds the amount of revenue to be received in that year as estimated in the resolution authorizing the issuance of the bonds. The authority shall take all action necessary and possible to impose, maintain, and collect rates, charges, rentals, and taxes, if any is pledged, sufficient to make the revenue from the pledged source in the year at least equal to the amount of principal and interest due in that year.

(3) The bonds may be sold at public or private sale and may bear interest as provided in 17-5-102. Except as otherwise provided in this section, any bonds issued pursuant to this chapter by an authority may be payable as to principal and interest solely from revenue of the authority and must state on their face the applicable limitations or restrictions regarding the source from which the principal and interest are payable.

(4) Bonds issued by an authority or municipality pursuant to the provisions of this chapter are declared to be issued for an essential public and governmental purpose by a political subdivision.

(5) For the security of bonds, the authority or municipality may by resolution make and enter into any covenant, agreement, or indenture and may exercise any additional powers authorized to be exercised by a municipality under Title 7, chapter 7, parts 44 and 45. The sums required from time to time to pay principal and interest and to create and maintain a reserve for the bonds may be paid from any revenue referred to in this chapter, prior to the payment of current costs of operation and maintenance of the facilities.

(6) Subject to the conditions stated in this subsection, the governing body of any municipality having a population in excess of 10,000, with respect to bonds issued pursuant to this chapter by the municipality or by an authority in which the municipality is included, may by resolution covenant that in the event that at any time all revenue, including taxes, appropriated and collected for the bonds is insufficient to pay principal or interest then due, it shall, subject to 15-10-420, levy a general tax upon all of the taxable property in the municipality for the payment of the deficiency. The governing body may further covenant that at any time a deficiency is likely to occur within 1 year for the payment of principal and interest due on the bonds, it shall, subject to 15-10-420, levy a general tax upon all the taxable property in the municipality for the payment of the deficiency, and the taxes are limited to a rate estimated to be sufficient to produce the amount of the deficiency. In the event that more than one municipality having a population in excess of 10,000 is included in an authority issuing bonds pursuant to this chapter, the municipalities may apportion the obligation to levy taxes for the payment of, or in anticipation of, a deficiency in the revenue appropriated for the bonds in a manner that the municipalities may determine. The resolution must state the principal amount and purpose of the bonds and the substance of the covenant respecting deficiencies. A resolution may not be effective until the question of its approval has been submitted to the qualified electors of the municipality at a special election called for that purpose by the governing body of the municipality and a majority of the electors voting on the question have voted in favor of the resolution. The special election must be held in conjunction with a regular or primary election. The notice and conduct of the election is governed, to the extent applicable, as provided for municipal general obligation bonds in Title 7, chapter 7, part 42, for an election called by cities and towns and as provided for county general obligation bonds in Title 7, chapter 7, part 22, for an election called by counties. If a majority of the electors voting on the issue vote against approval of the resolution, the municipality may not make the covenant or levy a tax for the payment of deficiencies pursuant to this section, but the municipality or authority may issue bonds under this chapter payable solely from the sources referred to in subsection (1).
