OLATHE, Kan. (AP) — The Great Mall of the Great Plains in Olathe will close in mid-to-late fall. The owners of the 786,000-square-foot mall said in a statement Monday that economic realities such as the economic downturn and changing buying habits prompted the closing. The mall has struggled to remain profitable since it opened in 1997. VanTrust, the asset manager for the property, says it tried to find potential uses for the existing property but the structure, maintenance costs and layout making it unlikely the current building will be preserved. The developer is working with the Olathe Chamber of Commerce and Economic Development Council to find the best use for the property.
