A key official with the Greater Des Moines Partnership said planning for a year-round public market and urban farm will pick up this year despite questions over the future of one of the leading sites, the eastern half of Kaleidoscope at the Hub. Tim Leach, senior vice president of downtown development, said a site hasn’t been chosen for the market, and fundraising hasn’t started. But he expects action this year, with the help of the city, the county, Iowa State University and Christensen Development. Also among the options is building the market rather than placing it in an existing building, Christensen Development President Jake Christensen said. Blackbird Investments will acquire that part of Kaleidoscope in a swap with EMC Insurance Co. for 701 Walnut St., the former Younkers site where Blackbird had planned a tower development. The companies did not divulge their plans, and Leach said he has no information about the future plans.
