Bonsall FAQ
Do I need a grading permit in San Diego County?
Yes, if your project involves moving more than 200 cubic yards of material or if cuts or fills exceed 8 feet in vertical height. Smaller projects may still need permits depending on slope and location.
Can I direct drainage onto my neighbor's property?
No. Drainage must be properly designed to not increase runoff onto neighboring properties. Altering natural drainage patterns that cause damage creates civil liability.
Who prepares grading plans?
Grading plans for projects requiring permits must be prepared by a licensed civil engineer registered in California. Plans must comply with the County's Grading Ordinance design standards.
Escondido FAQ
Can I regrade my backyard in Escondido without a permit?
Only if total earth moved is under 50 cubic yards AND no new slope exceeds 3 ft AND no drainage patterns change. Otherwise, a grading permit is required.
What happens if my neighbor's new grading floods my yard?
Report to Code Enforcement for permit review, and separately you may bring a civil nuisance claim under CA Civil Code §3479. Escondido can require the grader to correct drainage to avoid private liability.
