Rancho Santa Rita
Rancho Santa Rita was a 8,894-acre (35.99 km2) Mexican land grant in the Amador Valley and western Livermore Valley, which is in present day Alameda County, California.
It was given in 1839 by Governor Juan Alvarado to Jose Dolores Pacheco.
The rancho included present day Pleasanton, Asco, and Dougherty.
Rancho Santa Rita was granted in 1839 to Pueblo de San José alcalde Jose Dolores Pacheco. It extended east from present day Foothill Road, with the Rancho Las Positas adjacent in the eastern Livermore Valley, Rancho San Ramon on the north and the Rancho Valle de San Jose on the south, Pacheco was an absentee landowner, but had a small adobe built in 1844, which is no longer standing. In 1854, Francisco Alviso, the son of Pacheco's majordomo (ranch manager), Francisco Solano Alviso, built the adobe ranch house that still stands on Foothill Road in the Alviso Adobe Community Park overlooking Amador Valley.
A claim for Rancho Santa Rita was filed with the Public Land Commission in 1852, and the grant was patented to John Yountz, administrator of the estate of José Dolores Pacheco in 1865.
In 1853, Rancho Santa Rita was sold to Augustin Alviso, grantee of Rancho Potrero de los Cerritos, by the heirs of Jose Delores Pacheco, Juana Pacheco and Salvio Pacheco. In 1854, Samuel B. Martin and West J. Martin purchased Rancho Santa Rita. They sold the ranch in 1865, and moved to Oakland.
