McClellan Air Force Base (1935–2001) is a formerUnited States Air Force base inCalifornia, located in theNorth Highlands area ofSacramento County, seven miles (11 km) northeast ofSacramento.[1]
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 hisConsolidated P-30 which he was flight testing crashed nearCenterville, Ohio.[2]
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 theNational Museum of the United States Air Force.
TheUnited States Coast Guard previously operatedCoast Guard Air Station Sacramento at McClellan AFB as a tenant activity, operating and maintaining severalHC-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.[3] 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.[4] 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.[5] It is also home to AmeriCorps*NCCC Pacific Region[6]
TheAir Force Reserve's604th Regional Support Group, part ofFourth Air Force, was planned to move toMarch Air Reserve Base, CA., in July 1997, as a result of variousBase Closure and Realignment Commission (BRAC) changes.
In 2005, the McClellan Aviation Museum changed its name to theAerospace 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 asBeale AFB,Travis AFB and the since closedMather AFB. The museum hosts educational programs to schools in the local area.[7]
In 2015, theSacramento Bee reported that McClellan Airfield had been designated as aSuperfund site, because theEnvironmental Protection Agency has identified 326 waste areas on the base.[8] Water wells closest to the base in the Rio Linda-Elverta district, have had the highest levels ofhexavalent 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.[9]
The McClellanRestoration Advisory Board provides a forum for the local community, regulatory agencies, and Air Force to share information on current and future environmental cleanup programs and reuse at the former base.[10]
