Population Density:

After Mexican independence from Spain in the early 19th century, Spanish colonists were given land grants, one of which was Rancho El Sobrante, deeded to Juan Jose and Víctor Castro in 1841. The grant's boundaries were unusually complicated, as they were to be determined by the boundaries of the surrounding grants: San Antonio, San Pablo, El Pinole, Boca de la Cañada del Pinole, Acalanes, and La Laguna de los Palos Colorados. In this sense, the rancho was el sobrante, the remaining area. Legal disputes concerning the borders and the claims of squatters continued for four decades, with much of the land sold to pay court and attorney costs. Victor Castro was left with 549 acres (2.22 km2) of the original grant. He built an adobe dwelling in what is now El Cerrito, and became one of the first members of the Board of Supervisors of Contra Costa County. Castro died at the age of 90 in 1897. Some of his descendants still live in the area of Castro Ranch Road.

Population Density:

After Mexican independence from Spain in the early 19th century, Spanish colonists were given land grants, one of which was Rancho El Sobrante, deeded to Juan Jose and Víctor Castro in 1841. The grant's boundaries were unusually complicated, as they were to be determined by the boundaries of the surrounding grants: San Antonio, San Pablo, El Pinole, Boca de la Cañada del Pinole, Acalanes, and La Laguna de los Palos Colorados. In this sense, the rancho was el sobrante, the remaining area. Legal disputes concerning the borders and the claims of squatters continued for four decades, with much of the land sold to pay court and attorney costs. Victor Castro was left with 549 acres (2.22 km2) of the original grant. He built an adobe dwelling in what is now El Cerrito, and became one of the first members of the Board of Supervisors of Contra Costa County. Castro died at the age of 90 in 1897. Some of his descendants still live in the area of Castro Ranch Road.
