On June 24, 2008, the Yolo County Board of Supervisors adopted a Construction and Demolition (C&D) Ordinance that requires construction, demolition, and renovation projects to dispose of their job site waste in an environmental manner.
Furthermore, the Yolo County ordinance is superseded by CALGreen—California’s Green Building Standards Code. CALGreen promotes environmentally responsible, cost-effective, healthier places to live and
work. As of January 1, 2017, the CALGreen building code waste diversion requirement states that at least 65% of construction materials generated during new construction or demolition projects shall be diverted from the landfill. The County considers the reuse and recycling of C&D debris essential to compliance with AB939.
