Status context. The village linked Compass project update says construction is actively underway at the former Sears headquarters campus. It separately records development approval on February 17, 2025 and the first Building 1 permit and construction start on March 19, 2025. The label is the village reported construction stage, not completion or operation of all five planned buildings. The substation work remains a separate component.

Exact site not published; shown at county level. The dot is placed inside the county for the map and is not the site, its address or a parcel.
