Dispatched for a brush fire that appears to be unattended; incident called in by a motorist that was passing by. Upon our arrival, we were met by a friend of the homeowner who states they take care of the property and were burning some yard waste. The fire is noted to be across the road from the residence with no structures nearby. The fire is small and appears manageable by the person at the scene. We advised this person to contact us if the fire were to get out of control. The person agrees to do so. All units cleared the scene and returned to quarters.
