Storm Drains and Drainage Ditches
The City of Irvine is responsible for installing and maintaining storm drains and drainage facilities within the Public Works Street Division public right-of-way.

Storm drains and ditches divert the water after a storm or shower away from road surfaces, public access areas, or low basins where water collection could be unhealthy and dangerous. Water instead flows into drains and ditches where it can be safely channeled.  

The system consists of inlets, catch basins, open county storm channels, ditches, underground pipelines, and detention ponds. The division routinely inspects and cleans to remove any obstacles obstructing the flow of water and makes structural improvements to insure that the system is efficiently and reasonably handling water flow.

Citizens are reminded to never dispose of leaves, grass clippings, or trash into the drainage system or in a location, such as a roadway, where debris could be swept into the system by storm water. 

For more information, or to report a storm drain or ditch that is backed up or flooding, contact Public Works at 949-724-7600.
