Chino Valley was once part of the immense Rancho Santa Ana del Chino grant conferred in 1841 to Don Antonio Lugo, the former alcalde of Los Angeles. Forty years later, a portion of the rancho was sold to Richard Gird, an American entrepreneur and prospector from Tombstone, Arizona. With characteristic Yankee ingenuity, Gird increased his holdings to nearly 50,000 acres in a short period of time, planned and developed the present-day city of Chino, and transformed the valley into an agricultural empire based on sugar beet production. Chino later emerged as the center for the California dairy industry, evolved into a suburban weekend refuge for pleasure-seeking Los Angelenos, and continues today as a desirable community for growing businesses and comfortable living.
