Nearly 50 firefighters battled a 3-acre grass fire on a hill next to a shopping and business center in the community of Blackhawk on Wednesday afternoon, according to a San Ramon Valley Fire Protection District official.
The fire district initially received a report at about 12 p.m. of a fire that was burning not far from Blackhawk Plaza, battalion chief Dan McNamara said.
McNamara said the blaze was contained around an hour later by responding fire crews.
He said a bulldozer caught fire for an unknown reason and flames spread to the surrounding vegetation.
There were no injuries reported as a result of the fire.
