Shortly before 1 a.m., Tualatin Valley Fire & Rescue firefighters were dispatched to the report of a commercial fire in the 7000 block of Southwest Nyberg Street.
A person in the same business complex saw smoke inside the unoccupied business and called 911.
The first-arriving crew reported seeing a smoke-filled convenience store with flames coming from the roof. This building was associated with automotive refueling. However, the business was closed at the time of the fire with no threat of fire extension to the fuel pumps.
Fire crews were faced with heavy smoke conditions and intense heat. Crews quickly extinguished the main body of the fire. Due to the complexity of the building, the fire extended to a large crawl space. A second alarm was requested by the incident commander to bring additional crews to the scene to assist with fire extinguishment and overhaul operations.
The fire was deemed under control at 2:08 a.m.
The complex where the fire was located houses several attached businesses. The fire was isolated to the one business with some smoke damage to adjoining businesses.
The fire caused extensive damage to the convenience store. No injuries were reported.
A fire investigator is on scene working to determine the cause of the fire. TVF&R crews were assisted by Lake Oswego Fire, Tualatin Police Department, and Metro West Ambulance.
