ESD25-00372 Patterson Sand & Gravel Bank Stabilization Sheet Pile Wall Extension Grading Permit

The Patterson Sand & Gravel Bank Stabilization Sheet Pile Wall Extension Grading Permit, identified by project number ESD25-00372, involves the installation of a 200-foot long sheet pile wall extension along the north bank of the Bear River in Placer County, California. Located at Assessor’s Parcel Number 018-032-001-510, the project site encompasses a river bank levee and mining haul access road situated approximately 1,900 feet west of the mine wash plant and offices at 8705 Camp Far West Road in the Sheridan area. This work builds upon previous grading permits and serves as a critical emergency measure to prevent a pit capture event, which would risk the uncontrolled release of impounded water from a 70-acre mine wash water settling pond into the river system. The project is managed by the Placer County Community Development Resource Agency, with Claudia Garcia serving as the primary technical contact. Due to the necessity of protecting natural resources and preventing catastrophic flooding, the project has been granted a Notice of Exemption. It is categorized as exempt under CEQA Section 15307 and is statutorily exempt under Section 15269(c) as an emergency project. While the scope of work and location are clearly defined, specific financial details, including the estimated contract value and pricing schedules, are not provided in the current documentation.
