From 1797 to 1846, the area (future West Hills) was part of Mission San Fernando Rey de España (Mission San Fernando). After Mexico won independence from Spain, it later became part of Rancho Ex-Mission San Fernando in Alta California. In 1845, a separate land grant for Rancho El Escorpión was issued by Governor Pío Pico to three Chumash people: Odón Eusebia, Urbano, and Urbano's son Mañuel. It encompassed the land west of present-day Woodlake Avenue in West Hills, with its adobe ranch buildings (present 1840s—1960s) sited beside Bell Creek near present-day Bell Canyon Park.
