Authorities are investigating a fire that burned at least five vehicles at the San Luis Obispo water treatment plant on Tuesday as possible arson.
Multiple homeless people have encampments in the area, and one homeless man was seen standing and watching as firefighters responded to the blaze. The man remained by the scene of the fire response, despite emergency personnel requesting that civilians leave the area.
Shortly after 4:30 p.m. on Tuesday, a caller reported a fire burning off the Bob Jones Bike Trail near the intersection of Los Osos Valley Road and Highway 101. Firefighters arrived at the scene and found an approximate 50-by-50-foot area of vegetation burning near the decommissioned city utilities facility. Five vehicles that were being stored at the facility were fully engulfed in flames.
Crews extinguished the vegetation and vehicle fires and prevented the blaze from spreading into the surrounding area.
During the incident, San Luis Obispo police officers and Cal Fire law enforcement personnel conducted a search of the surrounding area with assistance from the SLO County Sheriff’s Office K-9 team. California Department of Fish and Wildlife personnel also responded and provided support. Authorities did not make any arrests.
Officials describe the fire as suspicious. Arson investigators are continuing to investigate the cause of the blaze. They have yet to make a determination as to who may be responsible.
Authorities ask that anyone who witnessed suspicious activity in the area of the fire, or has information that could assist investigators, contact the San Luis Obispo Police Department non-emergency line at (805) 781-7312.
