The first session Tuesday was at the St. Louis Gateway Classic Foundation. The agency will hold two more sessions this week: from 4 to 6 p.m. today at the Katy Cavins Community Center in O’Fallon, Ill., and from 4 to 6 p.m. Thursday at the Crestwood Community Center.

The relocation has set off a bi-state battle between Missouri and Illinois politicians for the new facility, which will house 3,000 employees.

Collins said the agency held an input session on Monday with employees at the current facility.

“Their main concern is location and commute time from where they already live,” Collins said.

The agency has a satellite facility in Arnold that will not be moved.

Collins said the U.S. Air Force, which controls the land on the current site, would decide what to do with the current facility, which includes buildings from the old St. Louis Arsenal that date back to the U.S. Civil War. The agency said those buildings had become too old for their high-tech work and mission.
