Through the heart of California’s largest metropolitan area, the Santa Monica Mountains National Recreation Area extend from Elysian Park overlooking Los Angeles City Hall to the Oxnard Plain. The Santa Monica Mountains are unique to California as a largely undeveloped coastal range in the midst of a major metropolitan area with both coastal and mountain ecosystems.
While the range itself is a physically and ecologically integrated area of over 223,000 acres, a history of fragmented political jurisdictions led to piecemeal development and uncoordinated planning which threatened to ruin the area’s natural open space and recreational value.
