Firefighters have two brush fires under control that broke out on a dry hill near southwest Pleasanton Monday mid-morning.
The first fire, which was a three-alarm fire reported around 10:30 a.m., occurred near Sunol Boulevard and just east of I-680. It started near the highway and burned up the hill near Happy Valley Road, threatening several homes, Alameda County Fire Division Chief Jim Call said.
The second fire, which was smaller, was reported at the same time and was just south of that area, according to Mike Miller of Livermore-Pleasanton Fire. Both were under control by noon.
He said the cause is under investigation.
The fires caused minor structural damage, and all people in the area were evacuated, Call said. No homes were lost. Officials will be on scene most of the day.
About 25 units from Cal Fire, Alameda County Fire and Livermore-Pleasanton Fire Department responded to the fire. A Cal Fire helicopter and a fire plane provided assistance through a water drop and a flame-retardant material drop.
Some access roads near the fire have been closed by officials. CHP says motorists should expect delays on I-680 through the area.
