Grading and drainage in El Cajon are regulated under ECMC Title 15 (Building & Construction) and Title 16 (Subdivisions). A grading permit is required for earthwork exceeding 50 cubic yards or affecting drainage patterns. Development must not increase stormwater runoff to adjacent properties.
The City of El Cajon requires grading permits for earthwork exceeding 50 cubic yards, cuts or fills exceeding 5 feet in depth, or any grading that alters natural drainage patterns. The Engineering Department reviews all grading plans for compliance with the California Building Code grading provisions and local standards. Development projects must manage drainage so that post-development runoff does not exceed pre-development rates and volumes. Drainage must be directed away from foundations and adjacent properties. Projects in FEMA-designated floodways are subject to the city's Flood Damage Prevention Ordinance, which generally prohibits development within floodways. Hillside grading on the steep terrain east of the city center requires additional geotechnical review.
Grading without a permit is a violation of ECMC Title 15. Penalties include stop-work orders, required restoration of natural grade, and fines under the general penalty provisions. Altering drainage that causes damage to adjacent properties may result in civil liability.
