A grass fire suspected to be caused by an arsonist was 80% contained early Friday morning in San Jose’s Santa Teresa foothills, officials said.
The fire had burned 90 acres, threatened homes and prompted evacuation orders for a few hours Thursday before the orders were lifted, according to Cal Fire.
No destruction or injuries have been reported.
Officials believe six separate fires were intentionally set shortly before 6 p.m. near Colleen Drive, said Capt. Brian Palodichuk, of the San Jose Fire Department. One unidentified suspect was in police custody.
Crews expected to work through the night to reach full containment while officials worked on a “repopulation plan” for evacuated residents, officials said.
Police evacuated homes west of Graystone Lane along Pfeiffer Ranch Road to Deer Hollow Drive around 7:30 p.m., Palodichuk said. Fire crews worked to protect structures and air tankers dropped water from above as the vegetation fire spread through the valley.
The Almaden Community Center, 6445 Camden Ave., opened as an evacuation center for residents impacted by the fire.
