Reclamation Plan

The Reclamation Plan

Today, CEMEX is in the process of updating the quarry’s reclamation plan with one that is environmentally and economically superior to the existing Lone Star plan approved in 1987.

In Alameda County, a land use permit is required for reclamation plans, sometimes referred to as restoration plans.  There will come a day, many years from now, when the quarry has no more aggregate to mine. Reclamation Plans prepare for that day so that the property can benefit the public and the environment, and provide for reclamation to occur even as the quarry is in operation.

A reclamation plan and a mining permit are NOT one and the same. A reclamation plan is required under State law to detail how a quarry will be restored to a stable condition that supports a beneficial future use of the property when mining ceases. It is not an operational permit or an extension of the quarry’s vested mining rights. The quarry has been operating since at least 1906 and has vested rights that run with the land as long as the quarry remains in operation. What’s more, if CEMEX’s proposed reclamation plan is not accepted by the County, the quarry will continue operations under the current less-favorable Lone Star Reclamation Plan.

We are confident the Livermore and Pleasanton communities will come to appreciate CEMEX’s plan and its benefits.


Retiring Lake A, and Transfer to Public Use

  • There will be no more mining in Lake A
  • CEMEX will prepare Lake A to meet reclamation requirements for its transfer to Zone 7 water agency
  • CEMEX has proposed landscape and habitat improvements to return Lake A to a more natural state


Remainder of Eliot Facility

  • Once finished, Lake B 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
