The incorporated area of Sawtelle, to the south of the unincorporated area, includes the Sawtelle neighborhood, a district of Los Angeles. It is roughly bounded by the Interstate 405 freeway to the east, National Boulevard to the south, Centinela Avenue to the west, and Bringham Avenue, San Vicente Boulevard, and the V.A. grounds on the north. Greater Los Angeles Health Center is in the unincorporated area. The district was once an independent municipality, but was consolidated with Los Angeles in 1922. The area extends about to either side of Santa Monica Boulevard, running westward about 1.3 miles (2.1 km) from Interstate 405 (the San Diego Freeway) and Sawtelle Boulevard, toward Santa Monica, ending at Centinela Avenue. Because the incorporated Sawtelle area now represents the northern part of West Los Angeles, it is bounded on the north by Brentwood and Westwood, which bound West Los Angeles. To the south is the rest of West Los Angeles, which is not considered part of the Sawtelle district.
