S.D. Codified Laws § 9-38-80
A governing body may by ordinance create a recreation board, the membership to be determined by the governing body, to operate a system of public recreation, playgrounds, and children's parks, except that in first and second class municipalities having a park board, the powers and duties of a recreation board may be delegated to the park board of the municipality, which board shall then be designated as a park and recreation board, which, in addition to its powers and duties relating to parks, shall have all the powers and duties of a recreation board as provided in this chapter. The governing body of a municipality may exercise all the powers and duties of a recreation board in lieu thereof if it determines the same to be in the best interest of the municipality. The ordinance creating the board shall specify the number, the qualifications, the term of office of the members, the frequency of board meetings, the officers to be selected and a description of their duties, the number of members necessary for a quorum, and the scope of the board's authority.
