McClellan Air Force Base

For the vast majority of its operational lifetime, McClellan was a logistics and maintenance facility for a wide variety of military aircraft, equipment and supplies. Initially known as the Pacific Air Depot and Sacramento Air Depot, in 1939 the base was renamed for Major Hezekiah McClellan, a pioneer in arctic aeronautical tests. Born in 1894, he died on 25 May 1936 when his Consolidated P-30 which he was flight testing crashed near Centerville, Ohio.{{Cite web|title=History|url=https://www.afcec.af.mil/Home/BRAC/McClellan-AFB/History/|access-date=2020-06-10|website=www.afcec.af.mil}}

In 1986, the U.S. Air Force established the McClellan Aviation Museum on what was then McClellan Air Force Base. The museum was later chartered by the National Museum of the United States Air Force.

The United States Coast Guard previously operated Coast Guard Air Station Sacramento at McClellan AFB as a tenant activity, operating and maintaining several HC-130 Hercules aircraft. CGAS Sacramento continues to operate at McClellan following its closure as an Air Force Base and is the only remaining military aviation unit and installation on the airfield.

In 1993, the base was selected by the Pentagon for closure. At first, McClellan was scratched from a list of bases to be closed, but that decision was faced with allegations that the Clinton administration was playing politics.{{cite web|last1=Pine|first1=Art|title=2 California Bases May Return to Closure List : Defense: Head of review panel cites concerns that McClellan, Presidio were dropped for political reasons|url=https://www.latimes.com/archives/la-xpm-1993-03-23-mn-14183-story.html|website=Los Angeles Times|access-date=19 May 2017|date=1993-03-23}} The base was eventually selected for closure, and there were plans to offset the expected loss of $1.5 billion, and 11,000 jobs, to the California economy. The plan relied on privatization and other investment to offset the economic and employment losses.{{cite web|last1=Pine|first1=Art|last2=Richter|first2=Paul|title=Revised Plan for McClellan Base Sent to Clinton|url=https://www.latimes.com/archives/la-xpm-1995-07-10-mn-22416-story.html|website=Los Angeles Times|access-date=19 May 2017|date=1995-07-10}} The base is now McClellan Business Park, a growing business enclave that hosts a diverse mix of companies spread across more than 8 million square feet of space of all types. This former military facility is now home to hundreds of private companies, as well as state, federal and local government agencies.{{Cite web|url=https://www.mcclellanpark.com/About/History|title = History}} It is also home to AmeriCorps*NCCC Pacific Region{{Cite web|url=https://ncccpacificregionresources.weebly.com/about-mcclellan-park.html|title = History}}

The Air Force Reserve's 604th Regional Support Group, part of Fourth Air Force, was planned to move to March Air Reserve Base, CA., in July 1997, as a result of various Base Closure and Realignment Commission (BRAC) changes.

In 2005, the McClellan Aviation Museum changed its name to the Aerospace Museum of California. Various military aircraft sit on display inside one of the hangars, and many more are outside on the flightline. The museum has displays which highlight the mission of the base when it was active, as well as neighboring bases such as Beale AFB, Travis AFB and the since closed Mather AFB. The museum hosts educational programs to schools in the local area.{{cite web|url=http://aerospacemuseumofcalifornia.org/about.html

In 2015, the Sacramento Bee reported that McClellan Airfield had been designated as a Superfund site, because the Environmental Protection Agency has identified 326 waste areas on the base.{{Cite web|url=https://cumulis.epa.gov/supercpad/cursites/csitinfo.cfm?id=0902759|title=Search Superfund Site Information|last=OSRTI|first=US EPA|website=cumulis.epa.gov|language=en|access-date=2017-10-18}} Water wells closest to the base in the Rio Linda-Elverta district, have had the highest levels of hexavalent chromium, which is a known carcinogen. Water from six of 11 wells tested above the state's maximum contaminant levels for chromium-6, which is 10 parts per billion.{{cite news|author1=EDWARD ORTIZ|title=Groundwater search turns up high carcinogen readings near McClellan|url=http://www.sacbee.com/news/local/health-and-medicine/article25119970.html|access-date=24 June 2015|work=The Sacramento Bee|date=June 21, 2015}}
