A decision in favor of the mission was reached and Rancho Los Nietos was reduced to nearly half of its original size, but still leaving Corporal Nieto with . At first it was called La Zanja, but later it was known simply as Rancho Los Nietos. Upon Manuel Nieto's death in 1804, Rancho Los Nietos passed to his wife and four children. Mexican declaration and partition

The rancho remained intact until 1833, when the Nieto heirs petitioned Mexican Governor José Figueroa for a partition and distribution of the land. In 1834, governor Figueroa officially declared the Los Nietos grant under Mexican rule and ordered its partition into six smaller ranchos. Rancho Palo Alto was the smallest of the six ranchos. It is unknown exactly where or how large was Rancho Palo Alto as it did not appear on the partition map. It included the Coyote Hills and most of the Arroyo de los Coyotes, and may have been combined into Rancho Los Coyotes. Legacy
Los Nietos Road in Santa Fe Springs and the unincorporated community known as West Whittier-Los Nietos are named after the rancho. References
