Corona requires erosion and sediment control measures on all grading and construction sites under Municipal Code Title 15 and the California Building Code. Hillside areas in south Corona near the Cleveland National Forest face stricter requirements due to steep slopes and wildfire-burn scar runoff potential.
The Corona Building Division enforces erosion control through the grading permit process under Municipal Code Title 15 (Buildings and Construction) and Appendix J of the California Building Code. Any grading project disturbing 50 cubic yards or more requires a grading permit, and the applicant must submit an erosion and sediment control plan prepared by a licensed civil engineer. Required BMPs typically include silt fences, fiber rolls, gravel bag berms, stabilized construction entrances, hydroseeding of disturbed slopes, and covering of stockpiles. Between October 1 and April 30 (the rainy season), all sites must have erosion control measures fully installed and maintained. Hillside developments in the Sierra del Oro and South Corona foothills face additional review under the Hillside Development standards, including slope stability analysis and revegetation requirements. Inspections occur before any winterization deadline and after significant rain events. Violations can result in stop-work orders, fines, and required cleanup of off-site sediment deposits. Post-fire areas may require additional emergency erosion control under coordination with Cal Fire and the Riverside County Flood Control District.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Corona code enforcement directly for current fines, enforcement procedures, and hearing options.
