Summary
Graded cut or fill slopes in Chula Vista may not exceed 2:1 (horizontal to vertical) under CVMC § 15.04.040, and the City Engineer or Director of Development Services can require a dedicated erosion control plan with the land development permit application under § 15.04.270(A)(11). The rules exist to keep graded land from becoming, in the code's words, barren and erosion-prone.
The inclination of each cut or fill surface resulting in a slope shall not be steeper than two horizontal to one vertical (2:1) except for minor slopes as herein defined. All constructed minor slopes shall be designed for proper stability considering both geological and soil properties. A minor slope may be constructed no steeper than one and one-half horizontal to one vertical (1.5:1) contingent upon: A. Submission of reports by both a soil engineer and a certified engineering geologist...

Full Breakdown
5:1, but only with submitted reports from both a soil engineer and a certified engineering geologist certifying the underlying soil and bedrock are strong enough, plus an approved special slope planting and irrigation program. 050(B), built without full soil testing, the slope may not exceed three horizontal to one vertical (3:1). 045. 270(A)(11) lets the City Engineer or the Director of Development Services require a dedicated erosion control plan alongside the contour maps, drainage plans, and soil reports otherwise required for the project.
Violations & Fines
The City Engineer can stop unpermitted or noncompliant grading immediately, require the work be removed or corrected, including habitat restoration, at the responsible party's expense, and, for an improperly built embankment, record a declaration of improper land development in the County Recorder's office, under CVMC § 15.04.235. Failing to submit or follow a required erosion control plan is enforced the same way, since it is a condition of the land development permit itself.
