On Sunday night August 19, 2018 the City of Colton Fire Department responded to multiple reports of a fire in the Santa Ana River bottom. The fire was reported shortly before 9:30pm behind the Cascade Warehouse in the 1200 block of S. Jefferson. The first arriving engine company reported smoke and fire showing from the river bottom with difficult access. Firefighters were eventually able to access the fire through the rear of the warehouse property. Firefighters located an old railroad bridge, which crosses the Santa Ana River, partially involved with fire. Firefighters were able to quickly contain and knock the fire down. The cause of the fire has yet to be determined.
