It consists of three adobe-walled elements arranged in an elongated C around a courtyard.","why_significant":"The nomination presents the house as a surviving example of Hispanic California adobe building traditions, combining a two-story Monterey Style block, a one-story Hacienda Style wing and a carriage house. It is tied to the Santa Margarita rancho and the ranchero culture of the Forster family. The property is said to retain a very high degree of integrity of materials, workmanship, location, setting, feeling and association despite lost elements such as the veranda.","narrative":"Las Flores Adobe is an 1868 rancho house located inside Camp Pendleton in northern San Diego County. Its three adobe-walled parts form an elongated C around a courtyard: a two-story Monterey Style residence, a one-story Hacienda Style wing, and a tall carriage house. Together they measure about 172 feet long. The first-story walls of the main block are roughly 36 inches thick and are covered in concrete plaster, probably applied in a remodeling around 1925. The nominated parcel of about 11.5 acres also holds a ca. 1900 windmill, mature cacti, locust and pecan trees, and several later Boy Scout buildings that do not contribute. The nomination ties the house to the Santa Margarita ranch and the ranchero way of life that persisted in southern California after the 1840s. It argues that the adobe keeps a high degree of integrity despite losses such as the veranda, removed in 1983. After a vacant period from 1968 to 1974, the Boy Scouts of America have leased it as a clubhouse.","period_of_significance":null,"architect_builder":null,"architectural_style":"Spanish Colonial (Monterey Style two-story segment and Hacienda Style one-story segment)","criteria":[],"status_note":"Leased to the Boy Scouts of America since 1974 and used as a social clubhouse; it was vacant from 1968 to 1974.
