Puente Hills Landfill Park

Puente Hills Landfill Park

Puente Hills Landfill is taking on new life as the future Puente Hills Landfill Park, a visionary project by the Los Angeles County Department of Parks and Recreation that is re-purposing what was once the nation’s second largest landfill into a park for all. Set to become LA County’s newest regional park, this transformation signifies a monumental step towards social and environmental justice for the vibrant communities of the San Gabriel Valley. The project’s conceptual design – which celebrates the region’s natural beauty while incorporating contemporary design elements – is the culmination of a year-long community engagement effort, the most robust outreach in County Parks’ history.

Situated just 18 miles from the LA downtown skyline along the Pomona Freeway with breathtaking views of the San Gabriel Mountains, this 142-acre park promises to be a transformative asset for both local residents and the entire region. Spearheaded by incredible public leadership and a landscape architect-led coalition of local organizations, the design process facilitated a robust series of workshops, focus groups, nature hikes, rides, and much more. Community input inspired a range of programming ideas that became a platform for the park’s design. Proposed park features include multi-use trails, an accessible elevated walk, nature play, a bike skills course, stair climbs, outdoor classrooms, native plantings, and flexible spaces for ceremony and performance. Puente Hills Landfill Park demonstrates the power of community-driven design to effect meaningful change for generations to come.
