In 2000, the Town of Killingworth purchased the 131-acre property for $670,000. Plans for a major recreation complex were developed but failed to win approval in town referendums in 2003 and 2004. The property went unused until 2007, when Peg Scofield requested permission to establish a community garden.
In April 2009, the Board of Selectmen established the Parmelee Farm Steering Committee (PFSC) to develop long-range plans for the use of this unique property. The Steering Committee supports the continued use by the Killingworth Community Gardens, use of the Parmelee Farmhouse by the Killingworth Historical Society, creation of walking trails, restoration of the farm buildings and hayfields, conducting workshops, as well as additional projects being discussed and developed on an on-going basis.
In early 2011, the property was listed on the State Register of Histoic Places by State Historic Preservation Office. The State Register of Historic Places is an official listing of properties and sites important to the historical development of Connecticut.
