Not just Maspeth. Look on Google Maps satellite view along Newton Creek and east of Sunnyside Yard. There is a ton of stuff that can either be relocated or built on top of. (If you drive through that area at ground level, it feels like you're in some post-apocalyptic horror movie.) It's not far at all, especially if you build a new road or light rail line connecting that area to LIC, which is reasonably feasible if the southern part of Sunnyside Yards gets decked over.
