- The council declared a state of emergency to speed access to state and federal aid and to help recover costs tied to the outage.
- Emergency 911 calls are being handled by the Solano County dispatch center and local police and fire units continue to respond, while many city offices and public services remain closed.
- City leaders convened an emergency meeting with a closed session to consider demands from a person or persons claiming control of city records and to discuss anticipated litigation.
