Controlled burns will be held Friday by the Atascadero Fire Department in the hills above Highway 41 West.
The burns will begin at 9 a.m. and conclude at about 3 p.m.
The purpose of the burn is to eliminate large piles of vegetation gathered as fire crews removed hazardous vegetation from the area.
Cal Fire will assist in the operation.
The Fire Department warns that smoke may be seen and smelled in many areas of the city Friday, and residents are encouraged to stay away from the burn area and keep windows and doors closed.
