Jurupa Valley FAQ
Do I need a grading permit for a small backyard regrade?
If you're moving less than 50 cubic yards and not creating cuts/fills over 5 ft on level ground, you generally don't need a permit — but you still can't direct runoff onto a neighbor's property.
Who approves my drainage plan?
City Engineering reviews drainage for permits; Riverside County Flood Control reviews plans within district right-of-way or affecting regional facilities (Pyrite Channel, Santa Ana River, Mira Loma Basin).
