Common Open Space. Any development in such district shall contain a minimum of 50% of the lot area as common open space. The undevelopable area of the lot may be included within such common open space. Such common open space shall be of a character and quality acceptable to the Board of Supervisors. In addition, there shall be such provision for the ownership and maintenance of the common open space as is reasonable to ensure its preservation. To this end, the Township may accept the dedication of land or any interest therein for public use and maintenance, but the Board need not require that land proposed to be set aside for common open space be dedicated as a condition of the approval of the subdivision or land development. The Board shall require the landowner to provide for and establish an organization for the ownership and maintenance of the common open space consistent with the requirements of the Pennsylvania Uniform Condominium Act, and such organization shall not dispose of the common open space by sale or otherwise, except to the Township or, after approval of the Board, to an organization established to own and maintain the common open space. If the common open space deteriorates or if, in the judgment of the Board, it is not maintained in a reasonable manner in accordance with any approved plan or otherwise, the Township may proceed to remedy any such deficiency by enforcement of any applicable township ordinance or by injunctive relief or otherwise.
