The City of San Diego maintains 84 miles of concrete and dirt drainage channels and ditches that are designed to handle water flow from storm drains and canyon runoff and "channel" the water into the bay or ocean. There are also numerous miles of privately owned and maintained channels and ditches within the City. The Storm Water Department 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. This will help minimize the possibility of flooding and help improve water quality.

To report pollution entering our channels and ditches, use our Service Request system.

Information about maintenance of the City's channels and ditches can be found at the Routine Channel Maintenance Activities web page.

Information about the 2010/2011 Emergency Channel Maintenance Activities can be found at the Sorrento Channel Maintenance or Nestor Channel Maintenance webpages.

Future maintenance of the City's channels and ditches are included in the Master Storm Water System Maintenance Program.
