During the great Los Angeles flood of 1938 , the creek flooded , causing damage and destruction . In 1969 , the creek overflowed its banks again , causing damage in Redlands and inundating two-thirds of Loma Linda . Many of the bridges over the creek washed away , and Loma Linda Academy was completely flooded . These floods led to controversial calls for flood control on the creek . The federal government made appropriations for channelization of the entire creek in 1988 , but local opposition to the measure was strong . Eventually , a compromise measure was reached , in which the creek was only partially channelized in 2008 by the US Army Corps of Engineers . In 2010 , the creek again flooded parts of Loma Linda . In 2013 , the Corps of Engineers completed a flood control mitigation project which included maintenance and revegetation
