San Joaquin County Proclaims Local State of Emergency
January 1, 2023

Stockton, Calif. - Effective January 1, 2023, the Directors of Emergency Services for San Joaquin County proclaimed an emergency due to the series of winter atmospheric rivers. The emergency was proclaimed because San Joaquin County was affected by a “public calamity” when the Board of Supervisors was not in session.

This state of emergency will expire in seven days unless confirmed and ratified by the Board of Supervisors.

County officials state that the storm that began on December 28, 2022 caused extreme damage to the safety of people and property within the County. This included local flooding of communities and local infrastructure that put extraordinary stress upon levees and water systems.

The San Joaquin County's Office of Emergency Services is tasked with collecting damage estimates from County departments, cities within its jurisdiction, and special districts. This includes unincorporated areas of the County where additional impacts have diverted local resources from day to day operations. The impacts of these storm will likely be beyond the control of services, personnel, equipment, and facilities.
