Crews got a warehouse fire under control in the northeast part of the valley Sunday night.
It started around 7 p.m. near Lincoln Road and Alto Avenue.
A total of 8 engines, 3 trucks, 3 rescues, 3 battalion chiefs and an air resource unit responded to the incident with approximately 54 fire personnel.
Officials are still determining the cause of the fire but they think it may have started in a large stack of cardboard in the warehouse.
There were no reports of injuries.
