The Santa Monica Canyon drainage area encompasses a total of approximately 9,987 acres. This area is roughly divided up by the City of Los Angeles (51.2 percent) and State of California recreational areas and parkland (47.3 percent).

Bounded by Mulholland Drive (mountain ridge) to the north, Calabasas Peak ridge to the west, Farmers Fire Road to the east and the Santa Monica Bay to the south, the area drains a variety of runoff sources such as bacteria and e.coli (from horses and livestock, and leaking or defective septic tanks). This has resulted in exceedences in beach water quality standards where the canyon discharges into Santa Monica Bay.

The rectangular grid areas in blue designate their Thomas Guide map page number equivalents.
