S.D. Codified Laws § 34A-6-25
No franchise may be granted by any municipality pursuant to § 34A-6-24 unless the governing body of the municipality submits the proposition of issuing the franchise to a vote of the electors at a general or special election called for that purpose. Before submitting the proposition, the governing body shall first approve the proposed franchise by ordinance, incorporating the proposed franchise in full and providing for submission of the proposition at an election to be held not sooner than thirty days after the publication of the election and proposition. The notice of election and the proposition shall refer to the ordinance by number and shall include the full title of the ordinance. No such franchise or franchise ordinance is effective unless the proposal to grant the franchise is approved at the election by a majority vote of the electors.
