Revised SMP-30 Use Permit, Sunol Valley Aggregate Quarry

Present Land Use
County General Plan: "Water Management"; County zoning: A: Agriculture, subject to County Surface Mining Ordinance
Document Description
The current Sunol Valley Aggregate Quarry is under operation on an approximately 323-acre site. The quarry was approved for aggregate mining by the County in 1992 pursuant to Surface Mining Permit-30 (SMP-30). Under this currently effective permit, quarry operations can continue through year 2021. An adjacent 58-acre parcel has now become available, and the applicant seeks to revise the SMP-30 permit to increase aggregate reserves by expanding and deepening the quarry pit, which will ultimately be used for water storage. The proposed revised permit (the project) seeks to increase the area under permit, deepen the excavation, extend the permit expiration date to 30 years after approval, to add an on-site asphalt batch plant and a concrete batch plant, and to amend the Reclamation Plan for the site.
