Abstract: The US Congress codified the National Historic Preservation Act of 1966 (NHPA), the nation’s most effective cultural resources legislation to date, mostly through establishing the National Register of Historic Places (NRHP). The NHPA requires Federal agencies to address their cultural resources, which are defined as any prehistoric or historic district, site, building, structure, or object. Section 110 of the NHPA requires Federal agencies to inventory and evaluate their cultural resources, and Section 106 requires them to determine the effect of Federal undertakings on those potentially eligible for the NRHP. Fort Hunter Liggett is located on California’s Central Coast within Monterey County. The fort has been used as a training facility for large-scale maneuvers and live-fire exercises since its establishment as a US Army training facility in 1941. The periods of significance for Criterion A are: from 1769 to 1833, relating to the founding and development of Mission San Antonio de Padua; from 1834 to 1923, relating to Euro-American land grants and ranchos; from 1923 to 1940, relating to Hearst’s purchase of the property and subsequent development; from 1940 to 1945, relating to the establishment of the Hunter Liggett Military Reservation (HLMR) and activities related to WWII; from 1959 to 1970, relating to the establishment and buildup of CDEC; and from 1975 to 1980, relating to HLMR’s redesignation as Fort Hunter Liggett and associated development. This report provides a comprehensive historic context for ranges, features, and buildings at Fort Hunter Liggett in support of Section 110 of the NHPA.
