Sargent Ranch Partners, LLC (Applicant) proposes to construct, operate for 30 years, and subsequently reclaim the Sargent Quarry Project on an approximately 403-acre site in Santa Clara County. The Project is a sand and gravel mining operation that includes an aggregate processing facility. The Project site is located in the Sargent Ranch property, approximately 4 miles south of the city of Gilroy and approximately 1 mile south of the U.S. 101 and Highway 25 interchange. The mined material (sand and gravel, collectively called “product”) would be extracted in four phases over 30 years and would be transported off-site by a combination of truck and train hauling. Final reclamation of the last surface mining phase and the aggregate processing facility would occur at the end of the Project’s life. The project requires adoption of a Reclamation Plan and issuance of a Conditional Use Permit for the 30-year life of the quarry.
