Great Mall of the Great Plains. Details are sketchy, but developers have a $305 million plan to redevelop the 270-acre site of Olathe’s demolished Great Mall at Interstate 35 and 151st Street. The plan, heavy on sports and fitness, was unveiled in early January but is very preliminary. An application for Kansas STAR bonds was submitted in December by VanTrust Real Estate LLC, with partners including Woodbury Corp. of Salt Lake City and Loretto Properties. Plans call for hotels, apartments, restaurants, retail and multipurpose sporting facilities.
