Research notes
One of the few true statewide land-use preemptions. Local governments may impose setback, height, decommissioning, and noise standards no more restrictive than state-default. Applies to both counties and municipalities, including home-rule. Federal conflict check: utility-scale wind interacts with FAA Part 77 obstruction surfaces around ORD/MDW and Scott AFB.
