Memorandum
Date: June 2, 2026
To: The Honorable Lake County Board of Supervisors
From: Lars Ewing, Public Works Director
Subject: Approve Continuation of a Local Emergency Due to Geotechnical Instability Causing Roadway Failure and Embankment Erosion on Socrates Mine Road and Authorizing Emergency Contracting Pursuant to Public Contract Code Sections 22050 and 20395(d)
Executive Summary:
Socrates Mine Road is a county-maintained road that provides essential access to residents, businesses, and properties near Middletown. Recent field observations and staff evaluations have identified significant geotechnical instability at multiple locations on the road. These locations are experiencing significant slope movement including embankment erosion, subsurface instability, and loss of soil strength. These conditions have resulted in undermining of the roadway structural section, creating a substantial risk of continued degradation and potential sudden or catastrophic roadway failure if not promptly addressed.
The conditions pose an immediate threat to public health, safety, and welfare, including loss of safe vehicular access, impaired emergency response access, and risk of injury, property damage, or isolation of residents. Furthermore, the nature of the failure is geotechnical and highly variable, requiring specialized investigation, design, and construction approaches. Work will involve adaptive methods responsive to evolving subsurface conditions, including but not limited to geotechnical analysis, slope stabilization systems, drainage improvements, and reconstruction of the roadway structural section.
The emergency was declared on May 5, 2026.
