Residents are urged not to dispose of leaves or grass clippings into open drainage systems or to place debris or storage in a location that would impede the flow of water into these systems. Such action may result in serious flooding. In the event of flooding due to heavy rainfall that may be caused by a blockage of the storm drainage system, call the Engineering Division at (909) 394-6240, Monday through Thursday from 7:30 am to 5:30 pm and Friday 8 am to 5 pm. If you are calling during non-business hours please feel free to leave a message and someone will get back to you as soon as possible.
