Union has taken steps to make itself open to big projects like this one. In 2013 to 2014, Procter & Gamble built a $90 million, 1.8-million-square-foot distribution center at Union’s Global Logistics Air Park, bringing more than 800 new jobs to the city.
That building was constructed on 140 acres near the northwest section of Jackson Road and Dog Leg Road, just west of Dayton International Airport.
Planning for Union’s Global Logistics Air Park began more than 20 years ago when the city invested $2 million to extend water and sewer lines to make “Global Logistics Air Park” ready for development.
