Sun Valley Watershed

Sun Valley Watershed is an urban subwatershed tributary to the Los Angeles River. It is bordered by Tujunga Wash on the west, the Burbank Airport on the east, Hansen Dam on the north and Burbank Boulevard on the south. It is approximately 2,800 acres (or 4.4 square miles) in size, located approximately 14 miles northwest of downtown Los Angeles, and encompasses the communities of Sun Valley and portions of North Hollywood.

The watershed is highly developed with industrial, commercial, and residential developments. Active gravel mines, landfills, numerous auto-dismantling operators, and various other industrial and commercial land uses make up more than 60% of the watershed. In the watershed are two neighborhood parks and one public library.
