This is what multiple items on the list already suggest. Relating to the first proposal, from Gensler, there already exists a proposal called the Triboro RX[0] to add transit along existing freight rail lines that run from the Bronx through Maspeth and Bushwick, ending up in Bay Ridge. This sort of project, if implemented well, would bring people and development to these areas. Unfortunately, it's difficult to obtain money for a prospective project such as the RX that wouldn't immediately benefit existing NYC residents. One could make a case that residents of transit-starved Maspeth would appreciate the new train line, but they also might be politically opposed, as it would bring upheaval and development to the neighborhood. Aecom's proposal also suggests new transit: that 1 train extension could make a big difference. Red Hook has always been transit-starved, but, as with Maspeth, I can see grassroots opposition to the community upheaval that would result from a 1 train extension. Perkins + Will's proposal to rezone the Newtown Creek industrial zone would meet more of the residential need in the Bushwick area, but the transit in that region is not yet sufficient to meet a huge influx of new residents: the L and the M are already heavily loaded. The bus network would prove less useful than expected for interesting historical reasons: NYC's bus network exists along legacy streetcar routes that abruptly terminate along borough borders (for what I imagine were political regions prior to borough unification in 1898), and this section of Bushwick lies along the Brooklyn/Queens border. So, the bus lines in the area don't always make sense or take you where you need to go. Some of the other ideas don't really relate to handling an influx of 9M residents, but are in the Robert Moses vein of improvements (i.e. leveraging existing yet overlooked details creatively to benefit the public), particularly the "under highway" public space and the "subway stations as public plazas" ideas. The Javits Center and schoolyards ideas are kind-of silly, and the suspended tram line, while a cool idea, wouldn't be worth the money.
