Orland Park FAQ
What erosion controls do I need on my construction site?
Sites disturbing 0.5 acres or more need a Soil Erosion and Sediment Control Plan with silt fence, inlet protection, and stabilized construction entrance. Sites disturbing 1 acre or more also need NPDES coverage.
What about a small home addition?
Small sites must still prevent sediment from leaving the property and clean any mud tracked onto Village streets. Building permit conditions typically address these requirements.
Who do I report a muddy construction site to?
Contact Orland Park Public Works at (708) 403-6350 or Code Enforcement at (708) 403-6150. Track-out onto Village streets is a frequent complaint trigger.
Skokie FAQ
Do I need erosion control for a residential project?
Yes if you are disturbing meaningful amounts of soil. Silt fencing, inlet protection, and prompt stabilization are standard expectations. Larger projects (1+ acre) require an IEPA NPDES permit.
Who inspects erosion controls?
Skokie Public Works and Community Development inspectors during construction. For IEPA-permitted sites, EPA compliance staff may also inspect. Neighbors may report violations.
What about sediment on the street?
Sediment tracked onto streets or deposited in storm inlets must be cleaned promptly. Failure to clean can trigger code enforcement and cleanup costs charged to the responsible party.
