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.

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.
