Lehigh Cement and Permanente Quarry Information

Although the hills outside the City of Cupertino have been mined for limestone since the 1930s, and the Lehigh cement plant operational since 1958, this heavy industry is now located adjacent to residential neighborhoods, creating ongoing environmental, health and safety challenges. When Supervisor Simitian returned to the Board of Supervisors in 2013, he pushed for increased oversight at Lehigh, holding the quarry and cement plant accountable to environmental regulations and aiding the public’s understanding and access to the state, federal, and local agencies that all have jurisdiction over some aspect of the site.​
