S.D. Codified Laws § 6-8B-6
The question of the issuance of bonds for the purchase or the construction of any building, facility, or improvement may be treated and submitted as a single proposition, and the governing body may determine, if bonds are authorized, whether the purchase or the construction thereof will better serve the interests of the public body. The authorization of bonds for the purpose of purchase or construction of any building, facility, or improvement includes the authorization to expend the proceeds for any equipment and furnishings, the purchase of any land, and the payment of all fees and expenses reasonably necessary to complete the building, facility, or improvement for the purpose intended. Expenditures for the above purposes need not be included in any annual appropriation ordinance of the public body.
