Riverside County
Construction sites in Jurupa Valley must implement erosion and sediment control BMPs under Title 13 Ch. 13.40 (stormwater) and the California Building Code Appendix J (grading). Sites disturbing 1+ acre require coverage under the State Construction General Permit (CGP) Order 2022-0057-DWQ and a Stormwater Pollution Prevention Plan (SWPPP) prepared by a Qualified SWPPP Developer (QSD). Smaller sites must still implement effective erosion and sediment controls per the Riverside County Water Quality Management Plan (WQMP).

Jurupa Valley FAQ
Do I need a SWPPP for my home addition?
Only if your project disturbs 1 acre or more (rare for residential additions). Smaller sites still need local BMPs — silt fences, inlet protection, and dust control.
What dust control is required?
AQMD Rule 403 requires watering, soil binders, or vegetative cover sufficient to prevent visible dust. Track-out onto public streets must be cleaned up immediately.
Temecula FAQ
Do I need erosion controls for a small backyard project?
Projects under 50 cubic yards and 5,000 sq ft typically don't need a grading permit, but you must still prevent sediment from leaving your property and entering storm drains.
What's required for hillside lots?
Hillside grading needs a geotechnical report, slope drainage analysis, and stabilization with hydroseed, jute netting, or terracing. Slopes over 3:1 need engineered solutions.
Can I grade during the rainy season?
Yes, but only with an approved winterization plan, daily inspections forecast-based, and immediate BMP installation if rain is expected within 48 hours.
