Lehigh Hanson Inc. announced today it won’t restart cement production at its Cupertino plant in the hills above Los Altos.
The company, which mines a large quarry, has been the target of environmentalists and other residents for years.
Specifically the company said it will not operate its clinker production, a key part of making cement. The plant will continue other ongoing operations, including serving as a distribution location as the company continues to evaluate the long-term strategy for the property. Lehigh hasn’t operated clinker production April 2020.
Materials sourced from the Lehigh facility have been vital in building the Bay Area since it began operation in 1939. Cement from the Permanente plant has been used in many key construction projects over the last 80-plus years, including the Golden Gate Bridge and San Jose International Airport.
