Our Storm Water System
The City’s storm water system is complex and extensive. The Department of Facility Maintenance is responsible for the maintenance of this separate sewer system of over 1,100 miles of pipes, culverts, stream channels, and swales, and nearly 28,000 catch basins.
In addition to the above infrastructure that conveys storm water to our streams and ocean, the City also has some infrastructure that is designed to reduce the non-point source pollutants entering the system. These include Green Stormwater Infrastructure, hydrodynamic separators, storm drain inlet filters, and trash capture devices (litter booms and automatic retractable curb inlet screen covers).
