A wind-driven brush fire that ignited Monday morning in Simi Valley grew from 10 acres to 720 acres in roughly three hours, destroying at least one home, threatening hundreds more, and forcing the closure of the Ronald Reagan Presidential Library. The Sandy Fire, named for the avenue where it first sparked, is the most significant California wildfire of the still-young 2026 fire season and a reminder that the conditions that fueled January 2025’s devastating Palisades and Eaton fires have not gone anywhere.
The Ventura County Fire Department received the first report at approximately 10:21 a.m. PDT, with flames spreading rapidly from the 600 block of Sandy Avenue near Sycamore Park. By 1:46 p.m., the fire had reached 720 acres with 0% containment. Roughly 500 firefighters were on scene by late afternoon, supported by three air tankers and six helicopters running what CAL FIRE described as aggressive aerial suppression in coordination with ground crews.
How It Started
Simi Valley Police Department Sgt. Rick Morton told reporters the fire was ignited when an individual operating a tractor hit a rock near the 2600 block of Rudolph Drive, generating a spark in dry brush. “When people are clearing large pieces of property, oftentimes they strike something not seen to the naked eye, which may cause whatever they’re clearing to catch on fire,” Morton said.
The cause remains officially under investigation by CAL FIRE, but the mechanism is consistent with a pattern that has dogged California fire prevention efforts for years. Equipment-related ignitions, particularly from tractors, mowers, and chains dragging on dry vegetation, are a recurring cause of fast-moving spring grass fires. The National Weather Service Los Angeles office had a Red Flag Warning in effect for the region, with northeast winds of 20 to 30 mph and gusts as high as 50 mph.
Evacuations and Closures
The Ventura County Sheriff’s Office of Emergency Services issued mandatory evacuation orders for Simi Valley Zones 32 through 35 and evacuation warnings for Zone 31 and Thousand Oaks Zones 6 and 7, covering the Lang Ranch, Verdigris, Eagle Ridge, and Woodridge neighborhoods. The orders stretch from north of Albertson Fire Road to south of Royal Avenue, and east of Wood Ranch Parkway to west of Edison Road.
A temporary evacuation point was established at Rancho Santa Susana Community Park at 5005 Los Angeles Avenue. Large animal shelter operations opened at the Ventura County Fairgrounds in Ventura, with small animal shelters at the Simi Valley Animal Shelter and the Camarillo Animal Shelter. The Humane Society of Ventura County is coordinating equine evacuation support.
The Ronald Reagan Presidential Library, which sits on a ridge above Simi Valley, evacuated and closed for the remainder of the day. The library’s chief of staff said the closure was prompted by surrounding road conditions rather than direct fire threat. The library holds roughly 74,000 items in its printed collection along with millions of pages of archival documents, photographs, and presidential artifacts.
The Simi Valley Unified School District evacuated students from Crestview Elementary and Mountain View Elementary to Simi Valley High School by bus. District officials said the schools had not been ordered to evacuate but chose to do so as a precaution. All students were reported safe.
State and Regional Response
Governor Gavin Newsom was briefed Monday afternoon, with the Governor’s Office of Emergency Services in active coordination with local first responders. “Residents should continue to follow the direction of emergency personnel as they work to contain this fire,” Newsom’s press office said in a statement on X.
Los Angeles Mayor Karen Bass deployed Los Angeles Fire Department resources to Ventura County, including three strike teams, hand crews, bulldozers, and a helicopter. “While there is no immediate threat to Angelenos, we encourage all residents to stay alert and heed official guidance,” Bass said.
Two smaller fires also broke out Monday in Southern California. The Sky Fire in the community of Ribbonwood in Riverside County stopped at 4 acres by 2:22 p.m., and the Cajon Incident near the 15 Freeway in San Bernardino County held at 5 acres as of 2:30 p.m. A separate small fire ignited in the Angeles National Forest near the Burro Peak area, prompting evacuation warnings.
The Larger Picture
The Sandy Fire arrives less than a week after Governor Newsom announced up to $30 million in new Regional Wildfire and Landscape Resilience grants through CAL FIRE on May 13. That funding, drawn from Proposition 4, the 2024 Climate Bond, brings the state’s total wildfire and forest resilience spending under the Newsom administration past $5 billion since 2019. The state has approved 383 wildfire projects across nearly 90,449 acres under the governor’s fast-track emergency proclamation, with projects clearing in as little as 30 days versus a year or more under traditional CEQA review.
The conditions feeding Monday’s fire reflect what state forecasters and CAL FIRE officials have flagged repeatedly heading into the season. Sierra Nevada snowpack is running 60 to 70% of average, with Northern Sierra basins closer to the mid-40% range. Fine grasses that sprouted after early winter rain have already begun curing across portions of the state, creating the fast-moving fuel that defined Monday’s blaze. The National Interagency Fire Center’s outlook had projected near-normal fire potential through May but warned that low snowpack and offshore wind events could shift the picture quickly.
The fire also lands roughly four months after the January 2025 Palisades and Eaton fires, which together burned approximately 40,000 acres, destroyed thousands of homes and businesses, and forced the evacuation of tens of thousands of Los Angeles County residents. The Eaton Fire alone reshaped the legislative session in Sacramento, generating dozens of wildfire-related bills and the package of recovery legislation Newsom signed in October 2025.
For Simi Valley residents on Trickling Brook Court, Rambling Road, and Hailey Court, the broader policy context offers little immediate comfort. Aerial footage Monday afternoon showed at least one home fully engulfed and others surrounded by flames as residents stood on rooftops with garden hoses. As of mid-afternoon Monday, CAL FIRE reported no injuries. The Ventura County Incident Information Line is active at 805-465-6650 for evacuation and sheltering questions.
The fire remained 0% contained at 720 acres as of the most recent CAL FIRE update Monday afternoon. Updates will follow as conditions develop.
