S.D. Codified Laws § 5-12-45
The Building Authority may provide, by resolution, for the issuance and sale of revenue bonds to finance all or any part of the capital cost of any land, buildings, or other improvements or equipment of a capital nature to be acquired by any person, partnership, association, limited liability company, or corporation and leased or acquired by the authority pursuant to § 5-12-43, and may loan the proceeds thereof to such person, partnership, association, or corporation. The issuance of the bonds is declared to be for a public purpose, and in selling, securing, and issuing the bonds and applying the proceeds thereof the authority may exercise all powers conferred on any municipality under chapter 9-54, and may pay from the proceeds the cost of any letter of credit, bond insurance, bond guarantee, put option, or other contractual right deemed necessary or desirable to secure the payment of or reduce the net interest cost on the bonds. The provisions of § 5-12-21, except the last sentence thereof, and §§ 5-12-23 to 5-12-27, inclusive, are applicable to the bonds only to the extent they are not inconsistent with the provisions of chapter 9-54. The authority shall also have the powers specified in §§ 5-12-27.1 to 5-12-39, inclusive, with respect to projects and bonds of the type herein described.
The Building Authority may provide, by resolution, for the issuance and sale of revenue obligations to refund or refinance obligations issued pursuant to §§ 5-12-42 and 5-12-43. In connection with such refunding or refinancing, the authority need not determine the fair market value of the improvements to be sold as otherwise required by § 5-12-42. For sufficient consideration received by the authority, as determined by the authority, the authority may enter into contracts with banks, investment bankers, or other purchasers for the sale and issuance of such revenue obligations to refund or refinance obligations issued pursuant to §§ 5-12-42 and 5-12-43, which contracts of sale shall be binding on the authority for the period stated therein, but not exceeding three years.
