San Diego County's Grading Ordinance (Division 7) requires permits for significant grading and mandates proper drainage design. Grading permits needed for 200+ cubic yards or 8+ foot cuts/fills. Drainage must be directed away from structures and neighboring properties.
The County Grading Ordinance contains criteria for grading permit requirements and design standards including slope design, setbacks, drainage, erosion prevention, and planting. Grading permits are required when quantities of excavation or fill result in movement of material exceeding 200 cubic yards, or when cuts or fills exceed 8 feet in vertical height. Drainage must be properly designed to direct water away from structures and neighboring properties. Cut and fill slopes must meet specific angle and compaction requirements. Retaining structures may be required for steep slopes. The County's Stormwater Standards Manual provides additional drainage requirements. Grading plans must be prepared by licensed engineers for projects requiring permits.
Grading without permits may result in stop-work orders, fines, required remediation, and permit revocation. Drainage violations causing damage to neighbors create civil liability.
