The Toyon Canyon Landfill is located within Griffith Park in the Los Feliz hillside neighborhood of greater Hollywood in central Los Angeles, California in the Santa Monica Mountains. The landfill began filling in 1957 and ended in 1985. A lawsuit in 1959 attempted to stop the project but was unsuccessful.[1] There was a move in the 1980s to expand the landfill into Royce's Canyon to the northwest, but that was defeated.
Landfill gas is collected from the decomposing waste and used for power generation. The landfill is managed by the Los Angeles Bureau of Sanitation which plans to have "low intensity open meadow area intended for passive recreational activities". The landfill was closed in accordance with the specifications of regulatory agencies in December 31, 2008. The landfill is maintained and monitored in accordance with SCAQMD 1150.1, provisions of AB 32, and other regulations for at least 30 years. The landfill is being landscaped with native plants such as toyon, oak, California poppy, lupine and others, while non-native plants such as mustard and tumbleweed are being actively removed.
In June 2012 the Los Angeles Regional Water Quality Control Board approved a revised Waste Discharge Requirements (permit) for Toyon Canyon, after opportunity for public input. It took effect July 1, 2012.
The landfill is clearly visible from California State Route 2, Route 134 (Ventura Freeway) and I-5 freeways in Los Angeles and from the surrounding hillsides. It is also visible on Google Earth. ( 34° 8'38.36"N 118°18'6.29"W)
During the May 2007 fire in Griffith Park, the helispot was used to help fight the fire.
