Corona FAQ
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.
