State Of Emergency Declared In County
Flood, Wind Warnings
Ready SJ

As a result of problems associated with the prolonged, heavy rainfall – also known as an atmospheric river – in the area, the Directors of Emergency Services for San Joaquin County proclaimed a local State of Emergency on Sunday, Jan. 1.

The emergency was proclaimed because San Joaquin County was affected by a “public calamity” when the Board of Supervisors was not in session.

“San Joaquin County has declared a Local State of Emergency due to the heavy rain we experienced over the weekend and the forecast of more rain this week,” said Fifth District Supervisor Robert Rickman, who represents Escalon on the county board. “Our Emergency Operations Center is activated and situational updates with allied agencies, and cities are being conducted. For further information and updates, please refer to”

The state of emergency expires in seven days unless confirmed and ratified by the Board of Supervisors, which can extend the emergency time period.

County officials said the storm that began on Dec. 28 caused extreme damage to the safety of people and property within the county, including local flooding of communities and local infrastructure and extraordinary stress upon levees and water systems.

The San Joaquin County 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, and the impacts of this storm will likely be beyond the control of services, personnel, equipment, and facilities.

The website features information on how to report weather related issues, has updated road closures throughout the county and sand bag availability information. There is also a link to flood preparedness and flood safety information.
