The Puente Hills landfill operated from 1956 to 2013. As early as 1990s, then State Assembly member Hilda Solis authored legislation to covert the landfill to a public park. 

 

That dream just crossed a major milestone to becoming reality, with the settlement of an $80 million lawsuit. However, the Sierra Club does not support current plans for the park. " the Disneyland that they are imagining for this park is not a good fit" says Sierra Club's Puente Hills Taskforce lead Eric Johnson.
