The changes also have the effect of keeping alive Rivers’ original intention of developing one or two hotels on the land. The current site of a large billboard will be moved where it will display messages electronically on three-sides. Those changes, which were quickly approved at Monday night’s Des Plaines City Council meeting, will result in better parking and landscaping and improved drives into and out of the property. Work will begin within the next few months on a number of changes on the 20-acres where Rivers Casino is located in Des Plaines.
