Municipalities face many restrictions on how they may use real property, and Pennsylvania law places additional statutory restrictions on a municipality's conveyance of property that has been used as a "public facility." The Donated or Dedicated Property Act, 53 P.S. Sections 3381-3386 (DDPA), states that "all lands or buildings … donated to a political subdivision for use as a public facility, or dedicated to the public use or offered for dedication to such use … shall be deemed to be held by such political subdivision, as trustee, for the benefit of the public with full legal title in the said trustee." "Lands" include all real estate, whether improved or unimproved, and a "public facility" includes, without limitation "any park, theater, open air theater, square, museum, library, concert hall, recreation facility or other public use." Any such lands or buildings are required to be used only for the purpose or purposes for which they were originally donated or dedicated, unless modified by court order.
