Aurora's Environmental Rules: The Rules That Matter
Every city handles environmental rules a little differently. In Aurora, Illinois, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Flood Zones
Aurora has significant Fox River floodplain areas. All development in the 100-year floodplain requires a permit. Flood insurance is mandatory for properties with federally-backed mortgages in flood zones. The city participates in the NFIP.
Key details: River: Fox River floodplain. Permit: Required for all floodplain development. Insurance: NFIP mandatory in flood zones. 50% Rule: Full compliance if improvements exceed 50% value.
Unpermitted floodplain development: stop-work order, fines, and forced compliance. NFIP violations: insurance penalties.
This is not one of those rules that cities tend to ignore. Aurora actively enforces its flood zones requirements.
Erosion Control
Aurora requires erosion control measures during construction per UDO standards. Silt fences, sediment barriers, and ground cover are required. The Fox River corridor has enhanced erosion control requirements. NPDES permits may be needed.
Key details: Required: All construction sites. NPDES: 1+ acre disturbance. Fox River: Enhanced requirements. Code: UDO maintenance standards.
Failure to maintain erosion controls: stop-work order. Sediment discharge to waterways: IEPA penalties.
Stormwater Management
Aurora requires stormwater management plans for development projects. The Fox River watershed drives significant stormwater requirements. Kane County Stormwater Management Commission provides regional oversight. Green infrastructure encouraged.
Key details: Plans: Required for development. Watershed: Fox River. County: Kane County Stormwater Commission. Green Infrastructure: Encouraged.
Non-compliant stormwater management: stop-work order. Drainage damaging neighbors: code enforcement action.
Grading & Drainage
Aurora requires grading and drainage plans for development projects. Water must not be directed onto neighboring lots. The Fox River watershed requires careful drainage management. Building permits include drainage review.
Key details: Plans: Required for development. Direction: Away from structures. Neighbors: Cannot direct water onto. Floodplain: Additional requirements.
Drainage damaging neighbors: code enforcement action. Unpermitted grading: citation and restoration order.
Coastal Development
Aurora is an inland city on the Fox River with no coastal development regulations. Fox River corridor properties are subject to floodplain regulations and stormwater management requirements. No coastal commission applies.
Key details: Coastal: Not applicable (inland). Fox River: Floodplain rules apply. FEMA: Flood zone compliance. County: Kane County stormwater oversight.
Floodplain development without permit: stop-work order. Erosion discharge: IEPA penalties.
Aurora is more permissive than most cities when it comes to coastal development. That said, there are still limits.
The Bottom Line
Aurora's environmental rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Aurora is broadly strict or permissive.
