Any open space acreage in addition to the minimum acreage required to be set aside in order to meet the open space requirements of a planned golf course recreational/residential development may be retained by the owner of the discontinued public or private membership recreational facility; provided, however, that such additional open space shall not be disposed of, by sale or otherwise, except to an organization conceived and established to own and maintain the open space for the benefit of such development, and, thereafter, such organization shall not be dissolved, nor shall same dispose of any of its open space without first offering to dedicate same to the Township. Such open space, in excess of the minimum open space required for planned golf course recreational residential development, after a public hearing and approval by the Land Use Board, may be devoted to uses or activities permitted in the PRRD Zone. The Land Use Board, in reviewing any application for use of such excess open space which has been retained by the owner of the recreational facility, shall be guided by the intent and purpose of the establishment of the planned golf course recreational/residential development in the PRRD Zone, in the first instance.
