Jurupa Valley FAQ
Can I wash my car in the driveway?
Individual residential car washing is a conditionally allowed discharge under most Phase I MS4 permits, but commercial washing must capture wash water. Avoid soaps reaching the storm drain.
Can I drain my pool to the street?
Only after dechlorination (chlorine residual non-detect) and no acidic/salty water. Pool acid and saltwater pool discharges are prohibited.
Riverside FAQ
Do I need a Water Quality Management Plan for a home remodel in Riverside?
Single-family remodels generally do not trigger WQMP requirements, but any project that disturbs soil must still install construction-phase erosion and sediment controls. Larger projects creating significant impervious area must submit a project-specific WQMP before discretionary approval. Check with Public Works Engineering at (951) 826-5341.
Can I wash my car in the driveway in Riverside?
The city discourages driveway car washing because soapy runoff flows untreated into storm drains and ultimately the Santa Ana River. Use a commercial car wash that recycles water, or wash on grass/gravel so runoff infiltrates.
