BOULDER — Macy’s Inc. (NYSE: M) won approval Tuesday night for the final piece of it’s effort to move forward with it’s long-planned redevelopment of its store in the Twenty Ninth Street shopping area. The Boulder City Council, as part of its consent agenda, voted to accept a $3 million donation to its affordable housing fund. Macy’s offered to make the payment rather than include affordable housing units in its redevelopment plans. Through a process of “adaptive reuse,” Macy’s, with help from Corum Real Estate Group Inc. and Trestle Strategy Group, plans to morph the store into a three-story, roughly 155,000-square-foot office building with about 7,700 square feet of retail space on the ground floor.
