StormwaterStormdrain

Stormwater runoff is generated from rain and melted snow that flow over land or impervious surfaces, like paved streets, parking lots and rooftops. The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment before making its way into and harming local rivers, streams, lakes and coastal waters.

 

The City of Stockton Stormwater Utility Division operates and maintains approximately 620 miles of pipe, 72 pump stations, and more than 100 discharge pipes that collect and route runoff from the streets and gutters to our local rivers, creeks, and sloughs.

 

Municipal Stormwater System

Municipal Separate Storm Sewer System (MS4), includes ditches, curbs, gutters, storm sewers, and similar means of collecting or conveying runoff that do not connect with a wastewater collection system or treatment plant.

To operate MS4, the City is required by the Clean Water Act to hold a MS4 permit and implement Storm Water Management Plan to reduce the discharge of pollutants into local waterways. 

 

Each year the City must provide an Annual Report to the State on the Stormwater Program and BMPs.
