Stormwater Management: Camarillo vs Oxnard

Can I wash my car in my Camarillo driveway?

Car wash water containing soap and pollutants should not flow into storm drains under CMC 9.32. Wash your car on a permeable surface (lawn or gravel) or use a commercial car wash. If washing on a driveway, divert water to a landscaped area rather than the gutter.

What can I not put in the storm drain?

CMC 9.32.050 prohibits discharging paint, oil, chemicals, pesticides, fertilizers, sewage, food waste, sediment, construction debris, pool/spa water, and any other pollutants into the storm drain system. Storm drains flow untreated to Calleguas Creek and the ocean.

Do new construction projects need stormwater plans?

Yes. CMC 9.32.080 requires construction sites to implement erosion and sediment control BMPs. Post-construction, Section 9.32.090 requires LID features for qualifying developments to manage stormwater quality and reduce runoff volume.

What are Oxnard's stormwater rules?

Oxnard prohibits pollutant discharge to storm drains under its NPDES MS4 permit. Construction sites over one acre need SWPPPs. New developments must include Low Impact Development measures.

Where does Oxnard stormwater go?

Oxnard's storm drains flow directly to the Pacific Ocean through channels including the Oxnard Industrial Drain and Santa Clara River estuary. No treatment occurs, making pollution prevention critical.

Do I need a stormwater plan for my construction project?

If your project disturbs one acre or more, you need a SWPPP and General Construction Permit coverage. Smaller projects may still need Best Management Practices per city requirements.
