Residents are advised to stay clear of flood control debris basins and channels. Persons can be swept away by a surge of water run off, mudflow, or debris flow. These areas are also dangerous when it is not raining as persons may become trapped in mud and debris by venturing onto what may appear to be stable soil. Do not drive where water is over the road as flood waters can rise rapidly and sweep a car and its occupants away.
For a road closure permit contact Permits Operation Support Supervisor (909) 387-1863.
