Reclamation Plan

The Reclamation Plan

There will come a day, many years from now, when the quarry has no more aggregate to mine. The reclamation and trail plan, adopted by Alameda County in June of 2020, prepares for this day — benefiting the environment and habitat, and improving public access to pedestrian trails.


This graphic introduces you to some exciting changes with some coming sooner than you might think and at no expense to Zone 7 Water Agency ratepayers.

Reclamation and Trail Plan

Until operations wind down, Lake B and the Plant Area will provide quality jobs and tax revenue, and continue to be a valued local source of construction aggregate.

Trails Icon

Landscaping improvements to improve views from neighboring homes and trails.

Habitat Restoration:
Major habitat restoration along a restored Arroyo Del Valle and throughout the property.

Lake A and Lake B will be transferred to the Zone 7 Water Agency at no cost to ratepayers. The transfer to Lake A will occur by 2024 and support water storage and stormwater management.

No Mining:
No mining in Lake A, located between Isabel Avenue and Vallecitos Road.

*The Livermore trail extension to the north of Lake A is not part of CEMEX’s amended reclamation plan. If the plan is approved by the County as submitted, then CEMEX will work with the City of Livermore to develop the trail connection.

Transferring Lake A to Public Use

  • Beginning as soon as 2022, CEMEX will prepare Lake A to meet reclamation requirements for its transfer to Zone 7 water agency
  • New landscaping and habitat improvements will return the property to a more natural state
  • The Livermore trail (North Lake A) will be extended around the equestrian property, bridging Lakeside Circle and Traviso Circle
  • There will be no more mining in Lake A

Remainder of Eliot Facility

  • Once mining is completed at Lake B, it will also be transferred to Zone 7 as the second link in the Chain of Lakes, providing water storage and groundwater recharge opportunities
  • To the south of Lake B and the enhanced Arroyo Del Valle, CEMEX will develop a new recreational bike and pedestrian trail along Vineyard Avenue
  • The remainder of the property, including the Lake J area, processing plant sites and surrounding lands will be returned to open space and/or agriculture
