Escondido, CA Environmental Rules: Erosion Control (2026)

Article 55 of the zoning code, Grading and Erosion Control, exists to assure that development protects the natural and topographic character of the environment by regulating grading and providing standards implementing best management practices to control stormwater and erosion during construction, per section 33-1050. Section 33-1053 requires a grading permit from the city engineer for most earthwork, exempting only narrow categories such as excavations under two feet deep, cut slopes under two feet high and no steeper than two-to-one, fill under one foot on terrain flatter than five-to-one, work under 200 cubic yards on a lot, and work that doesn't affect a drainage course, so long as the activity doesn't disturb sensitive species, habitat, or protected trees.

Section 33-1062 layers BMP duties onto every construction project: a civil engineer-prepared erosion control plan, the cash security described above, continual maintenance of temporary erosion control devices, and a 24-hour emergency contact who can mobilize equipment and personnel. Public rights-of-way, including parkway areas, must stay free of loose soil, mud, debris and trash at all times during construction. Before final inspection, permanent erosion protection kicks in: slopes under three feet must get ground cover or an erosion control system, and slopes over three feet must be landscaped with ground cover, shrubs, and trees on a permanent irrigation system.

General BMPs required to the maximum extent practicable include minimizing the graded area to only what construction needs, minimizing how long disturbed soil stays exposed, limiting grading during the wet season, and temporarily stabilizing and reseeding disturbed soil as quickly as feasible.
