A vegetation fire burned about 15 acres on a Pleasanton hillside Saturday night but was quickly halted without injuries or damage to buildings.
The fire was reported shortly before 9 p.m. in the area just east of Independence Drive at Bernal Avenue. Residents said it "was visible on the hillside near a large oak tree and spreading quickly," according to the Pleasanton Police Department.
The Livermore Pleasanton Fire Department, Alameda County Fire Department, and Cal Fire responded, while Pleasanton police closed streets and worked to notify people in some 50 nearby residences.
Streets were around 11:15 p.m.
The cause of the fire is under investigation. Anyone with information is encouraged to contact the Pleasanton Police Department at (925) 931-5100.
