The county legislative body may delegate, by resolution, to a parks and recreation board (or commission) the authority to conduct a parks and recreation program. Such a board consists of five members, at least two of whom may be members of the school staff, appointed by the chairperson of the county legislative body. Board members serve terms of five years except for the initial appointments so that the term of one member expires annually. Members of this board serve without pay. T.C.A. § 11-24-104. Any two or more counties or municipalities may form a joint board to conduct a joint parks and recreation program by agreement approved by the governing bodies participating. T.C.A. § 11-24-105.
