Roll Top Construction 2016 09 10

'With the help of a very generous donation from Jean and Ric Edelman the Park Authority was able to build and furnish a roll top observatory building at Observatory Park at Turner Farm.  The financial services radio talk show host was reminded of his childhood fascination with astronomy when someone gave him a 10-inch telescope to commemorate his 40th birthday. Edelman and his wife and business partner, Jean, share a passion for astronomy and are deeply committed to sharing the knowledge with younger generations."
"The Edelmans substantial contribution to the Fairfax County Park Foundation to fund Observatory Park is greatly appreciated. They will join Analemma Society members and other supporters at the ribbon cutting ceremony at 10 AM on October 1, 2016.  The park is located at 925 Springvale Road in Great Falls, VA."

Community Meeting Scheduled

FCPA Shares Update on Facilities, Programs at Turner Farm Park

The public is invited to attend a community meeting on Thursday, June 23, 2016, to hear information on facilities and programs at Turner Farm Park in Great Falls, VA. The meeting will begin at 7:30 p.m. at the Great Falls Public Library, Community Room at 9830 Georgetown Pike Great Falls, VA.

The Turner Farm is located at the intersection of Georgetown Pike (Route 193) and Springvale Road (Route 674). A master plan for this community park, originally 52 acres in size and representing the merger of three park parcels; Turner Farm purchase, Defense Mapping Agency site and Lexington Estates Park was completed in 2000. An additional 3.63 acres was purchased from the Turner family in 2010 which includes the Turner Farmhouse and several outbuildings.

The master plan for The Turner Farm envisioned a community park that complements the agrarian history and eclectic interests of the Great Falls area. The park supports observatory, equestrian and typical community park uses that are fully compatible with the site. (See: 

At the public meeting, Fairfax County Park Authority representatives will present information on use of the equestrian area including potential entrance and parking improvements, planned completion of the new Roll Top Observatory facility and an update on the Resident Curator Program. The presentation will outline site management plans including equestrian activities, use of the Roll Top Observatory and the status of the Turner Farmhouse as part of the Resident Curator Program. A question and answer period is planned following the staff presentation.
