Flood Control Infrastructure Maintenance
The County of Orange maintains 350 miles of concrete, rock lined and earthen flood control facilities. Flood control facilities are designed to handle water flow from storm drains and other runoff and "channel" the water into the bay or ocean. Operations & Maintenance conducts regular inspections and performs cleaning as needed. We encourage the public to notify us when a channel or ditch is blocked or filled with debris to help minimize the possibility of flooding and help improve water quality. There are also numerous miles of privately owned and maintained channels and ditches within the County.
