Project Description

The San Rafael Rock Quarry is owned and operated by San Rafael Rock Quarry, Inc., a subsidiary of the Dutra Group. The San Rafael Rock Quarry is an existing mining operation permitted by the County Department of Public Works in 1972, (Surface Mining and Quarry Permit #Q-72-03). The primary products currently produced at the Quarry include, rock, concrete aggregate, sand, asphaltic concrete and rip rap products that are used for road, levee, and other infrastructure construction. San Rafael Rock Quarry proposes to amend the Amended Reclamation Plan (ARP) to reschedule reclamation for an additional 15 years, which would be completed in 2044, instead of 2024. This would allow the Quarry to continue mining past the end date specified in the Amended Quarry Permit (AQP) – also 2024. The Quarry states that production levels in recent years have been lower than previously projected and permitted, and that the extra time is needed to achieve final reclamation grades. The County has determined that the change in reclamation timing will require changes to the conditions in the AQP governing timing of cessation of mining. 

Beginning on Monday, August 9, 2021, an Environmental Impact Report (EIR) Addendum was circulated for a 30-day period prior to a Board of Supervisor’s hearing. This early review period was provided as a courtesy to allow interested parties additional time to review and understand the findings of the Addendum before the project was scheduled for a public hearing at the Board of Supervisors.

This project is now under the purview of the County Department of Public Works. Please visit the County Department of Public Works San Rafael Rock Quarry ARP and AQP project page for more information about the project:
