That comment said there's pent up demand for a housing product and that Brooklyn is a great location for said product. That's two different things.
First, there is a pent up demand for urban oriented apartments in Jacksonville and the nation. Even local newspaper articles have announced the development of several throughout this city over the last few months.
Second, pent up demand aside, why would Brooklyn not be an ideal location for an urban styled apartment development? It's midway between downtown and Five Points, right off I-95/I-10, two blocks from the river, and across the street from thousands of office workers.
Looking at it from that point of view, 200 Riverside's location is a great site for an urban apartment project.
