A new Sam's Club planned for Glen Carbon is moving at a snails pace thanks to some development issues. The Village recently approved a second extension to THF Center Grove Development as it deals with mine subsidence and creosote deposits on the property at Center Grove Road and Troy Road. Some minor changes were approved for the site.

The changes involved parking and a retention pond, but for the most part the development remains unchanged. Developers are working on ways to deal with the issues of the former mining operation as well as removal of the creosote. Two previous deadlines have been extended, and the new deadline for a plan from the developer is now December 30. The Sam's Club will be located on the site of the former Four Flags Motors and the Goshen Do-It center, directly across the highway from the Home Depot.
