Los Angeles County Chair Pro Tem and First District Supervisor Hilda L. Solis joined residents and community leaders today to officially break ground on Puente Hills Regional Park, launching Phase 1 of one of the County’s most significant environmental justice and public space projects in decades.

This event marks the beginning of Phase 1 construction for the 140-acre Puente Hills Regional Park, converting the second largest landfill site of the country into a much needed destination for recreation, education, and community connection. The first phase of the park will serve unincorporated communities from the San Gabriel Valley, including Bassett, Avocado Heights, Valinda, Hacienda Heights, and Rowland Heights, as well as the City of Whittier.

‍

Phase 1 will include:

• Environmental Justice Center
• Park entry plaza
• Workman Mill Road trailhead and staging area
• Amphitheater for community performances
• Nature Play Zone
• Arts plaza
• Dog park
• Playgrounds
• Restrooms, parking, trails, and native landscaping

Phase 1 of the Puente Hill Regional Park is expected to be completed by Fall 2026.
