Under 60 ILL. COMP. STAT. 1/115-10 et seq. (2004), corporate township authorities are granted broad authority to establish subsidiary boards to study and make recommendations for the conservation of open space in order to “maintain or enhance the conservation of natural or scenic resources.” After such a board is established, a township board may acquire, designate, plan, and zone by ordinance areas to conserve open space and other natural resources, and promote sustainable development. A township may acquire land targeted for open space preservation located within or contiguous to municipalities via petition or condemnation, after due notice and hearing, and failure to respond by a municipality.
