Late last week, they began grading an area and now appear to be beginning work on pouring concrete as of yesterday.

This lot has been rumored to have a lot of things coming, but not sure what will ever materialize.  Some of the most recent and most high-profile rumors the Amazon HQ2 project and/or U of I "Discovery Partners Institute".
Time will tell...
