Trash to Treasure: New Park Set to Redefine Open Space in the San Gabriel Valley

Puente Hills Landfill Park, slated to open in 2027, will transform a former 1,300-acre landfill—the second largest in the U.S.—into Los Angeles County's newest regional park, offering 140 acres of trails, scenic vistas, and green space for a community historically impacted by industrial contamination and limited access to open space. As reported by Chris Greenspon and Joe Linton, the project reflects decades of planning and community input, addressing environmental justice while creating a sustainable recreational hub. The park will feature key areas such as the 40-acre Western Deck with playgrounds, gardens, and an ADA-accessible "Skywalk," along with an Environmental Justice Center housing classrooms, exhibits, and advocacy resources.

The park design balances the site's unique topography and environmental challenges, including methane off-gassing from the landfill, which closed in 2013 after storing 150 million tons of waste. Vegetated terraces and capped soil layers ensure safety while providing a foundation for trails, oak groves, and wildlife habitats. The initial construction phases, beginning in 2025, will focus on creating the Environmental Justice Center, entry plaza, and the Western Deck, while future phases will expand into the Eastern and Southern Decks, offering additional nature trails, a bird observation outlook, and native plant nurseries. 

Nike Hill, the landfill's peak, already offers panoramic views and serves as a popular hiking destination, showcasing the site's transformation potential. Accessible via the Schabarum-Skyline Trail, the hill is part of an existing 29-mile trail network that links to surrounding parks. The new park aims to enhance multimodal access, including bike lanes and transit connections, while delivering much-needed green space to underserved communities in the San Gabriel Valley. The Puente Hills Landfill Park exemplifies how urban planning and community engagement can turn industrial landscapes into vibrant, inclusive recreational spaces.
