Cemex’s Amended Reclamation Plan

Welcome to Clayton Quarry

The Clayton Quarry has been part of your community for over 70 years, providing a valuable source of construction aggregate for Bay Area neighborhoods, businesses and public infrastructure.  

In September of 2022, Contra Costa County approved CEMEX’s proposed amended reclamation plan, a plan that serves as a blueprint for how the quarry will transition to open space many years from now.
