Close proximity to a host research university — check. Sustainably designed and preferably LEED-certified buildings — check. A state-of-the-art telecom infrastructure — check. An office of commercialization — check. These used to define a cutting-edge and competitive research park. Not anymore. Today's "A list" parks, or districts, look more like towns, complete with transit, lodging, residential and retail. Besides those, the University of Maryland's Discovery District in College Park will soon have coworking space, thanks to a recent partnership among the university, global coworking provider WeWork and Chesapeake Realty Partners.
