The Core Development Area Partnership was formed in September 2020 in response to creating a working partnership between the Town of New Carlisle, Olive Township, the St. Joseph County Redevelopment Commission and the St. Joseph County Board of Commissioners. The partnership agreements detail the creation of a Core Development Area of the Indiana Enterprise Center (IEC) which is 2,920 acres of the larger 7,200 acre IEC Development Area. The Core Development Area is focused in the geography between State Road 2, Willow Road/Walnut Road, US Highway 20 and Smilax Road/Snowberry Road.
