San Fernando Valley

The San Fernando Valley is an urbanized valley located in Los Angeles County, southern California, defined by the mountains of the Transverse Ranges circling it. Home to 1.8 million people, it lies north of the larger and more populous Los Angeles Basin.

Nearly two thirds of the Valley's land area is part of the city of Los Angeles. The other incorporated cities in the Valley are Glendale, Burbank, San Fernando, Hidden Hills, and Calabasas.

Geography
The San Fernando Valley is about 260 sqmi bounded by the Santa Susana Mountains to the northwest, the Simi Hills to the west, the Santa Monica Mountains and Chalk Hills to the south, the Verdugo Mountains to the east, and the San Gabriel Mountains to the northeast. The northern Sierra Pelona Mountains, northwestern Topatopa Mountains, southern Santa Ana Mountains, and Downtown Los Angeles skyscrapers can be seen from higher neighborhoods, passes, and parks in the San Fernando Valley.

The Los Angeles River begins at the confluence of Calabasas Creek (Arroyo Calabasas) and Bell Creek (Escorpión Creek) at Canoga Park High School beside Vanowen Street in Canoga Park. These creeks headwaters are in the Santa Monica Calabasas foothills, the Simi Hills' Hidden Hills, Santa Susana Field Laboratory, and Santa Susana Pass Park lands. The river flows eastward along the southern regions of the Valley. One of the river's two unpaved sections can be found at the Sepulveda Basin. A seasonal river, the Tujunga Wash, drains much of the western facing San Gabriel Mountains and passes into and then through the Hansen Dam Recreation Center in Lake View Terrace. It flows south along the Verdugo Mountains through the eastern communities of the Valley to join the Los Angeles River in Studio City. Other notable tributaries of the river include Dayton Creek, Caballero Creek, Bull Creek, Pacoima Wash, and Verdugo Wash. The elevation of the floor of the Valley varies from about 600 ft to 1200 ft above sea level.

Most of the San Fernando Valley is within the jurisdiction of the city of Los Angeles, although a few other incorporated cities are located within the Valley as well: Burbank and Glendale are in the southeast corner of the Valley, Hidden Hills and Calabasas are in the southwest corner, and San Fernando, which is completely surrounded by Los Angeles, is in the northeast valley. Universal City, an enclave in the southern part of the Valley, is unincorporated land housing the Universal Studios filming lot. Mulholland Drive, which runs along the ridgeline of the Santa Monica Mountains, marks the boundary between the Valley and the communities of Hollywood and the Los Angeles Westside.

Government and political representation


The San Fernando Valley contains five incorporated cities—Glendale, Burbank, San Fernando, Hidden Hills and Calabasas—and part of a sixth, Los Angeles, which governs a majority of the Valley. The unincorporated communities (Census-designated places) are governed by the County of Los Angeles.
