Champaign, IL Environmental Rules: Erosion Control (2026)

Article V of Chapter 29.5, titled the stormwater management and erosion/sediment control regulations (Section 29.5-101), sets minimum standards for soil erosion from land disturbing activities inside the city, in the extraterritorial jurisdiction for subdivision infrastructure, and in annexation-agreement areas (Section 29.5-102). The scope provision lists what the regulations cover: construction site erosion and sediment control plans, preservation of natural site features, permit requirements, inspection and control of site work, a fine system to penalize violators, and implementation of stormwater programs meeting the IEPA's NPDES Phase II requirements.

Land disturbances are sorted into permit classes: Class I needs an IEPA ILR-10 permit for one acre or more; Class II covers disturbances between 2,000 square feet and one acre; Class III is the same size band but limited to utility company work (Section 29.5-112C). A land disturbance permit is required for any site meeting the disturbance definition, and construction waste such as concrete and asphalt washout must be prevented from reaching sewers or waterways, with a washout facility mandatory for all Class I permit sites (Section 29.5-109).

The City Engineer administers the article, may enter sites at any stage of construction to inspect for compliance, and issues administrative rules implementing the manual of practice referenced in Section 29.5-111 (Section 29.5-106).
