The Solano County Administrator's Office and Office of Emergency Services have declared a local emergency after a storm damaged levee infrastructure in the Suisun Marsh and Sacramento-San Joaquin River Delta.Officials said a combination of King Tides and December storms caused the damage. The aftermath included slips, seepage, erosion, wave wash, cracks and breaches. The Office of Emergency Services said Van Sickle Island sustained substantial damage. The levee had been repaired since storms in Feb. 2023, but it failed at a 150-foot breach, flooding the island.The proclamation of a local emergency will remain in effect for seven days until ratified by the Solano County Board of Supervisors, officials said. The Board of Supervisors will hold an emergency meeting on Dec. 27.By declaring a local emergency, it gives the county access to resources to mitigate the storm's impact and prevent further damage.Officials said the full extent of damage to the levee infrastructure can't be assessed until after the winter season.See more coverage of top California stories here | Download our app | Subscribe to our morning newsletter
