Crews will continue mop-up operations on the now 52.5-acre fire with fire investigators continuing to follow leads and indicators to determine a cause.   

No injuries have been reported. 

Original story from October 25: 

CAL FIRE says crews are mopping up after a brush fire prompted evacuations and threatened several homes overnight near Verdi. 

Truckee Meadows Fire & Rescue says the 47-acre Hill Fire started just before 10:45 p.m. Tuesday south of Dog Valley Road on the California side. 

The Sierra County Sheriff's Office is investigating. 

The Washoe County Sheriff's Office and Washoe County Sheriff's Office Search and Rescue held voluntary evacuations for those living between Dog Valley Road and Ridge Street.

"We have the Washoe County Sheriff's Hasty Team supporting us... anywhere from 40 to 60 homes are being evacuated in the area of Hill Lane to Bridge Street to Dog Valley Road, that general vicinity," says Adam Mayberry, Truckee Meadows Fire & Rescue.

The Washoe County Sheriff's Office says the Best Western Plus Boomtown Casino Hotel in Verdi has been designated as a staging area for evacuees. The Red Cross is assisting.
