Westborough is one of South San Francisco’s largest post-war housing developments. Built on diary land, the one-time “Callan Park” (named after its developers) was annexed by South City in 1964 after flirting with becoming part of Daly City. Ultimately, Westborough added some 8,000 residents to South San Francisco, pushing the character of the city away from its gritty, urban roots and toward the idyllic suburbia that came into vogue after World War II.
