The six residential projects that appear to have stalled are emblematic of a broader pattern for The District Detroit: Grand visions, but only partial execution.

There have been serious discussions about high-rise buildings with Baltimore-based Cordish Cos. in the past. But that was before the developer of what it calls “Live!” mixed-use districts around sports arenas quietly stopped working with the Ilitches last year, according to sources familiar with the matter. Crain’s reported Cordish’s departure in September.

In an interview last year, Chris Granger, group president of sports and entertainment at Ilitch Holdings Inc., said Cordish was still working with Olympia but didn’t go into detail. Multiple emails sent to Cordish over the past several weeks seeking an update weren’t returned.

There were plans for a pair of residential high-rises overlooking Comerica Park in collaboration with Cordish, Crain’s reported a year ago.

The Adams Tower would be on an Ilitch-owned surface parking lot and effectively wrap around the Grand Valley State University building — blocking its CoPa view — next to the Detroit Athletic Club. A source briefed on the plans said last year that the new tower would have baseball stadium-style seating for residents on its rooftop. The Montcalm Tower would be at Woodward and Montcalm Street, next to St. John’s Church.

But so far, there has been no forward momentum on those projects now that Cordish has bowed out.

Detroit-based Ventra LLC, former Detroit Economic Growth Corp. chief George Jackson’s company, had been serving as The District Detroit multifamily residential consultant but stopped working with ODM last year.

In addition, there was to be a hotel that took the place of the Hockeytown Cafe across from CoPa, as well as one immediately across from the new hockey and basketball arena.

Retail space that has been expected to line the Woodward overpass over I-75 has not moved forward.

“The reality is that major development often takes time,” said Jemison, the city’s chief of services and infrastructure. “There are projects outside of The District Detroit that were announced several years ago that are still not under construction, due to a variety of unexpected factors. When you take on a 50-block redevelopment, it’s not surprising that some aspects will move more quickly than others.”

Crain’s reported in August that the company hired Keith Bradford, a former Walt Disney Co. executive who had been vice president of the rebranded and expanded Downtown Disney, to oversee The District Detroit and help it move along as senior vice president of operations and development. Olympia has also been on a hiring spree, seeking to woo real estate professionals from other companies in the region with pay 30 percent or greater than what they were making at previous positions along with other perks.
