Stormwater Outreach

Storm drains were designed to collect rain and clean water runoff to prevent street flooding during storms. Local waterways become polluted when excess or leaking motor oil, antifreeze, paints, fertilizers, pet waste, soapy water, and pesticides wash into the storm drains. These consumer products are the number one source of pollution in our nation’s urban waters.

Preventing pollution at the source is the most effective way to avoid flooding and keep harmful substances out of our rivers, lakes and sloughs.

Storm Drain Markers

Storm drain markers are reminders that only rainwater should flow down storm drains. Storm drain markers can be installed on solid flat surfaces near storm drains. Email WaterFacts@stocktonca.gov to request free storm drain markers and instructions to install.

Annual Reports

The City submits annual Municipal Stormwater Program reports in accordance with:

  • the National Pollutant Discharge Elimination System Permit (NPDES) and 
  • the Water Discharge Requirements (WDR) General Permit for Discharges from Municipal Separate Sewer Systems (MS4).
  • Each report reflects all stormwater activities conducted for the fiscal year listed.
