County continues storm response as flooding, mud flows and road closures impact mountain and desert communities
 San Bernardino County Public Works is working around the clock to remove mud and debris in county communities impacted by the December storm.
San Bernardino County and partner agencies are engaged in storm response and recovery operations addressing the heavy rain, high winds, flooding and mud and debris flows impacting multiple communities near burn scar areas.
On Dec. 24, Governor Gavin Newsom proclaimed a state of emergency for San Bernardino County and several other counties impacted by the late December storms, including Los Angeles, Orange, Riverside, San Diego and Shasta. On Dec. 25, San Bernardino County CEO Luther Snoke declared a local emergency for San Bernardino County. These actions make the county and its residents eligible for forms of aid that might become available.
“We want to assure our communities that the Board of Supervisors and county departments stand with you,” said Board of Supervisors Chairman and Third District Supervisor Dawn Rowe. “We are focused on stabilizing our roads with an emphasis on safe access, as well as rounding up every available resource to keep you safe and assist you with your immediate needs and recovery.”
“I join our communities in thanking every firefighter, law enforcement officer, public works crew member and volunteer who has stepped up to serve and protect our residents,” said First District Supervisor Col. Paul Cook (Ret.), whose First District includes many of the hardest-hit communities. “We will continue to coordinate with our state, federal and local partners to stabilize our infrastructure, clear mud and debris, keep residents informed, secure assistance, and achieve a full recovery.”
Rowe and Cook urged the public to adhere to all road closures and barricades, avoid driving through floodwaters, and plan ahead before traveling.
San Bernardino County Fire has exited unified command in response to the incident. The San Bernardino County Office of Emergency Services continues emergency coordination, including sheltering and public information dissemination in partnership with the San Bernardino County Sheriff’s Department, County Fire, Public Works, Public Health, Animal Care and regional partners.
Life-safety operations: evacuations and rescues
San Bernardino County Fire reported heavy debris flows and flooding in Wrightwood and Lytle Creek, with crews assisting with evacuating residents in impacted homes. Additionally, fire crews conducted door-to-door checks in affected areas and advised residents in danger zones to evacuate immediately.
County Fire also reported an increase in swift water rescue calls, particularly in Hesperia, Phelan and Piñon Hills, including rescues of people trapped in vehicles. Multiple agencies assisted, including the Los Angeles County Fire Department, CalFire, San Bernardino County Sheriff and San Bernardino County Public Works.
More than 120 County Fire personnel supported operations on Dec. 24 to assist residents who needed help evacuating and to address ongoing life-safety concerns. County Fire reported one injury, minor in nature, involving a pediatric patient who was transported to a local hospital as a precaution.
Once immediate life-safety issues have been mitigated, County Fire reported crews will transition to property preservation efforts where conditions allow. These efforts may include damming, diverting water and salvaging property at affected structures.
Road closures and travel impacts
Many roads remain closed due to mud, debris, roadway damage and flooding. Residents should avoid unnecessary travel and confirm routes are open before leaving.

Cleanup, recovery and ongoing coordination
Ahead of the storm, San Bernardino County departments and nonprofit partners pre-positioned shelter resources and heavy equipment, coordinated staffing and prepared outreach and resource distribution—particularly for residents in mountain communities and other high-risk areas. County Public Works staged equipment and activated 24/7 crews working 12-hour shifts in advance of the storm, monitoring flood control cameras and stream gauges.
County Public Works crews are operating extended and split shifts to clear debris, stabilize flood control channels and reopen access to impacted roads.
