On December 11, 2025, Center for Biological Diversity (CBD), the City of Pittsburg, California, and real parties in interest requested that the California Superior Court stay proceedings in CBD’s California Environmental Quality Act (CEQA) challenge to the City’s approval of the Pittsburg Technology Park Specific Plan, a three-phase master planned development that included an approximately 368,551-square-foot data center in the first phase. The City, the real parties in interest, and CDB agreed to the incorporation of enhanced mitigation measures to address the project’s greenhouse gas, air quality, biological resources, water and energy demand, and noise impacts. The mitigation measures included rooftop solar and electric charging infrastructure requirements, participation in a renewable energy program to achieve 100% carbon-free electricity, and the owner’s payment of $750,000 to a foundation to distribute funds for sustainability and regional climate resiliency projects.
