S.D. Codified Laws § 11-8-38
A municipality may itself exercise its urban renewal powers, as defined in § 11-8-39, or may, if the local governing body by resolution determines such action to be in the public interest, elect to have such powers exercised by the urban renewal agency, created by § 11-8-40, or by the housing authority, if one exists or is subsequently established in the community. In the event the local governing body makes such determination, the urban renewal agency or the housing authority, as the case may be, shall be vested with all of the urban renewal powers in the same manner as though all such powers were conferred on such agency or authority instead of the municipality. If the local governing body does not elect to make such determination, the municipality in its discretion may exercise its urban renewal powers through a board or commissioner or through such officers of the municipality as the local governing body may by resolution determine.
