from Tri-Town to the three towns. Tri-Town asked the Navy to intervene, which has declined. In August, the state Senate enacted Starwood Land Ventures' proposed legislation and thus reduced Tri-Town's role. Tri-Town was reconstituted as the Southfield Redevelopment Authority that month. As of 2018, the development is known as Union Point, planned as a smart city with self-driving cars from Optimus Ride, about 4,000 homes, of commercial space, green roofs, ponds, and open space including hiking and biking trails. Plans include a market in the former hangar, arch, college campus, movie theatre, hotel, and sports complex. The development is adjacent to the South Weymouth station on the Old Colony Lines of the MBTA Commuter Rail. The development presented a bid for siting of Amazon HQ2, but did not make the finalist round of 20. On March 26, 2020, a fire broke out in abandoned buildings on the grounds of the former Naval Air Station, about from the nearest housing. The buildings, formerly officer barracks, were destroyed in what officials considered a "suspicious" fire. Days later, investigators determined it was arson. Military activities and museum The U.S. Coast Guard maintains a buoy maintenance facility near the old railroad spur to the station. An A-4 Skyhawk jet mounted on a pedestal in a small park called the "Shea Memorial Grove", named for Squantum reservist CDR John "Jack" Shea who was killed in action when the aircraft carrier USS Wasp was sunk during World War II, remains as a perpetual reminder of the site's naval heritage. The jet, the park, and a small Navy museum (the Shea Field Naval Aviation Historical Museum) located in the former base gymnasium building (The Shea Fitness Center) are maintained by a local veterans' organization called the Association of Naval Aviation Patriot Squadron. The museum serves as a repository of photographs, documents, and other artifacts pertaining to NAS Squantum and NAS South Weymouth.
