 Santa Clarita was incorporated in December 1987 as the union of four unincorporated communities, Canyon Country, Newhall, Saugus, and Valencia, most of which are situated within the boundaries of the former Rancho San Francisco, a historic land grant.The four communities retain separate identities, and residents commonly refer to one of them when asked where they are from.Santa Clarita is bounded on the west by the Golden State Freeway (I-5).
