At the request of Santa Clara County Supervisor Joe Simitian the County has compiled and issued a ten-year review of local, state, and federally recorded violations taking place at the Lehigh Southwest Cement property in unincorporated Cupertino. The Housing, Land Use, Environment and Transportation (HLUET) Committee reviewed the report on May 19, 2022 and forwarded it to the Board of Supervisors for its consideration.

Although the hills outside the City of Cupertino have been mined for limestone since the early 1900s, 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 company accountable to environmental regulations and aiding the public’s understanding of and access to the state, federal and local agencies that have jurisdiction over the site.
