Water Quality (Stormwater)

The City’s Water Quality (Stormwater) Program works to address water pollution affecting the municipal separate storm sewer system and waters of the United States. Much of our work relates to efforts undertaken to comply with National Pollutant Discharge Elimination System (“NPDES”) permits issued pursuant to federal and state law. For additional information, please contact the Planning & Environmental Services Department at (949) 639-0500 or via our online contact form.
