Southern California's Sandy Fire in Simi Valley reaches nearly 1,700 acres with 15% containment; evacuation orders remain

A brush fire dubbed the Sandy Fire, burning in the Simi Valley area, has grown to nearly 1,700 acres on Wednesday morning as crews continue to battle flames.

The fire ignited near Sandy Avenue shortly after 10 a.m. on Monday, had grown to 1,698 acres by Tuesday night after a flare-up began burning in a remote area between Simi Valley and Bell Canyon. As of Wednesday morning, containment of the fire had grown to 15%, according to Cal Fire.

On Tuesday, fire officials said the blaze had experienced significant growth due to shifting winds, steep terrain and canyon-driven fire behavior. Overnight, crews took full advantage of cooler temperatures and higher humidity levels.

More than 869 personnel have been assigned to the fire. Air and ground resources from across Southern California have been sent to help with the firefight of the Sandy Fire.

The Simi Valley Police Department said around 10:17 a.m., they received a report that an individual "hit a rock with a tractor" near the 2600 block of Rudolph Drive, which sparked the fire.

Sgt. Rick Morton said 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.

Andrew Dowd, the Public Information Officer for the Ventura County Fire Department, said the fire had destroyed at least one home. CBS LA spoke to neighbors near where the home was destroyed on Trickling Brook Court. They said the family who lived there had been there for decades.

Aerial footage of the fire on Monday showed neighbors springing into action to help one another by loading animals into crates. Many used hoses to water down dry vegetation.

Residents thanked firefighters for their quick response.

"The first responders, they were here, they did the magic that they do," said Don Sullivan. "They've been doing a great job. I've been watching the drops; they are right on target."
