Chino FAQ
Can I wash my car in the driveway in Chino?
Occasional residential car washing is generally allowed as a non-stormwater discharge under the San Bernardino MS4 permit, but commercial mobile detailers and fleet washers must capture or divert wash water. Avoid heavy detergent use and never wash near a storm drain inlet.
How do I report illegal dumping into a Chino storm drain?
Call Chino Police at (909) 334-3000 during business hours or (909) 628-1234 after hours. For paint, oil, or chemical spills also call the CalEPA 24-hour spill line at 1-800-852-7550.
Do I need a Water Quality Management Plan for my project?
Yes if your project is a 'priority development project' under Order R8-2010-0036 — typically creating or replacing 5,000+ sq ft of impervious surface, restaurants, auto-service uses, parking lots, or hillside development. The WQMP is submitted with grading/building applications to Chino Engineering.
Can I drain my swimming pool to the gutter?
Only after fully dechlorinating the water (let it sit 24-48 hours after stopping chemical additions, test for zero residual chlorine) and neutralizing pH. Chlorinated pool water is an illicit discharge.
