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

Project ESD25-00372, managed by the Placer County Community Development Resource Agency, involves a grading permit for the Patterson Sand and Gravel Bank Stabilization Sheet Pile Wall Extension. The project requires the installation of a 200-foot long sheet pile wall extension along the north bank of the Bear River to build upon previous work completed under permits ESD16-00153 and ESD19-00279. This work is designated as an emergency measure to prevent a pit capture event and the subsequent uncontrolled release of impounded water from a 70-acre mine wash water settling pond into the river system. Due to its nature as an emergency project to protect natural resources and prevent flooding, it is categorically and statutorily exempt under CEQA Sections 15307 and 15269(c). The project site is located at Assessor Parcel Number 018-032-001-510, specifically on a river bank levee and mining haul access road approximately 1,900 feet west of the mine wash plant and offices at 8705 Camp Far West Road in the Sheridan area of Placer County, California. The grading permit approval was granted on December 5, 2025, with the official notice of exemption signed on December 9, 2025. Claudia Garcia serves as the primary technician and point of contact for the lead agency. The project is classified under NAICS code 237990.
