Project Purpose. The purpose of the Project is to restore the ADV channel banks and Lake A shoreline to the pre-erosional alignments and also restore water surface elevation. The new ADV embankments at Lake A are designed to provide protection from a 200-year flood event. No mining will be occurring at the site as all activities will support the restoration and repair work associated with the Project.
Projected Timeline. Cemex and Teichert Construction (Contractor) will begin work on the Project during the week of June 22, 2026. Work is scheduled for completion by November 2026. During this time, you may observe construction equipment onsite for the duration of the Project. Construction activities will be limited to the hours of 7 am to 7 pm Monday through Friday, and 9 am to 6 pm on Saturday.
The Eliot Quarry, nestled between the communities of Pleasanton and Livermore, has been providing the region building materials since the late 1800s. The quarry’s sand and gravel can be found in the concrete and asphalt that built many of the Tri-Valley homes, neighborhoods, schools, parks, roads and businesses. This is the quarry’s legacy.
CEMEX’s adopted reclamation and trail plan prepares the property for the day when the quarry’s supply of sand and gravel is depleted – a blueprint for how the quarry will transition to open space as the quarry prepares to shut down its operations, years from now.
Watch this project video see what CEMEX’s quarry will look like in the future – new pedestrian trails, a water conveyance system and environmental restoration!
This website was created to introduce the public benefits of CEMEX’s plan and to be responsive to neighbors as reclamation requires intermittent construction. We encourage neighbors to view the reclamation page for the project timetable and to request email updates.
