The 20-acre East Bay hills vegetation fire that broke out Wednesday is 90 percent contained and has transitioned to patrol status, Oakland fire Battalion Chief Melinda Drayton said Saturday morning.
Patrols are in place now and no fire crews are remaining on the scene, Drayton said in an email.
Grizzly Peak Boulevard between Centennial and South Park drives is now open, Drayton said. The road was closed when firefighters were actively fighting the blaze.
Firefighters from the Oakland Fire Department and the East Bay Regional Park District Fire Department will patrol the area for the next few days to check for hot spots, according to Cal Fire.
The blaze was reported at 1:05 p.m. on Wednesday near Grizzly Peak Boulevard and South Park Drive.
Half of the fire was on Oakland land in the hills and half of the fire was on land owned by the Lawrence Berkeley National Laboratory that's mostly in Contra Costa County, fire officials have said.
University of California at Berkeley police spokeswoman Sgt. Sabrina Reich said on Thursday that the fire is being considered as a possible arson but Drayton has declined to comment on that, saying that Cal Fire is the lead investigative agency looking into the cause and origin of the fire.

Cal Fire Battalion Chief Mike Martin said at the scene late Thursday afternoon that the only thing he can say is that there's an open investigation into the fire and the probe could take days, weeks or even months.
