Eventually the farmland fell into the hands of the federal government. While the construction of the greenbelt community was underway, the Greendale Resettlement Administration used the farmland for a housing and and staging area. The land then once again became privately owned and used as an airfield. In fact, some of those individuals who used the airfield helped to later found the Experimental Aircraft Association, which is now located in Oshkosh.
In 1980, the farmland was purchased by the Milwaukee County Park System. A restoration project was soon underway so that the property structures and their histories could be properly interpreted and preserved. In 2004, the Milwaukee County Historical Society began managing the site. The historic site features a Cream City brick farmhouse, one of the last stone barns in the state, a workman's bunkhouse, threshing barn, and 75-foot kiln.
