East County Sand Mine

The East County Sand Mine project, authorized under Lake and Streambed Alteration Agreement EPIMS-SDO-41731-R5 issued by the California Department of Fish and Wildlife pursuant to Fish and Game Code Section 1602, involves the extraction of approximately 674,000 cubic yards of sand and topsoil from a 27.58-acre site in San Diego County, with mining concentrated in deep pits covering 17.87 acres to a depth of 415 feet above mean sea level. Topsoil removal will occur across the entire permitting area, and the site will be fully reclaimed over a 15-year period divided into six phases, including a mandatory five-year monitoring period after final reclamation. As part of remediation, the project will construct new creek channels for Slaughterhouse Creek and San Vicente Creek capable of conveying 100-year storm flows and expand the existing Anderson Channel to increase capacity, with these channels serving as mitigation for wetland, riparian, and Waters of the State impacts. An open space easement will be established over the mitigation portions of these waterways. The project will import and recycle 677,400 cubic yards of clean, inert soil, rock, and concrete for use as on-site fill, rip-rap, and for sale. All activities are subject to compliance with the California Environmental Quality Act, including a Mitigated Negative Declaration and a CDFW-approved Mitigation Reporting or Monitoring Plan, with no overriding environmental concerns identified. Regulatory oversight is shared between CDFW and the San Diego Regional Water Quality Control Board, with project execution and compliance monitoring managed under the direction of East County Sand Mine, LLC, and coordinated through San Diego County agencies, though no formal procurement contract with pricing, delivery terms, or federal acquisition clauses is present—this document serves solely as an environmental permit with associated reclamation obligations.
