^ nah, I think that article is rather alarmist. The key quote is here:
The base of this tower is not that big. If they are re-reviewing the NSRL route anyway, they'll try to compensate - it's actually a blessing that we are not talking about a transit project versus one developer, but rather a zoning plan...
I think you're possibly being too sanguine. As F-Line has explained repeatedly at the NSRL thread, there are only two possible routes for the NSRL, and after much vetting, the one that heads along the channel shoreline and then cuts back to under the Big Dig via the Hook Lobster site is the one with the greatest promise, by far.
MassDOT would be guilty of criminal malpractice if they allowed one of those two possible routes to get blocked, especially if it's the most viable route.
And granted, we are still just at zoning stage, but it makes zero sense to approve a zoning change that would allow the NSRL to get blocked at the latter site-specific permitting stage. Why the hell raise false hopes for a site owner at the zoning stage just to try to block them later?
And the cold reality is that this IS an issue where the interests of one site owner clash with the interests of an entire region's transit needs. Sucks to be that site owner, but it's been a known reality for decades. There are very very few instances where I come down in favor of eminent domain powers being flexed, but this is one of them.
The entire rest of the waterfront zoning change ought to be on what all the parties feel is best for the waterfront. On this one site, the zoning should be carved out into a transit-specific set of constraints, like a sub-surface easement. Everything on this site should devolve from the need to keep that NSRL path unobstructed. Given the way it angles across the site, I think that means keeping the foundations within a certain shallowness*, because I can't see how they end up not having the NSRL boring machine going under them one day. I'd be completely in favor of giving them a one-off exemption from ANY underground (or overground) parking requirements as a trade-off for the fact that they're maybe losing some overall mass due to the underground easement. And then let them go as tall as engineering will allow up above a future tunnel. I'd like to see something tall go there, but this is ABSOLUTELY the number one place in Boston where I'll fight to see tallness get whacked for the sake of the greater good. And not because of any damned shadows or any damned NIMBYs.
All that talk about MassDOT "re-reviewing" the possible NSRL route just sounds like Baker covering his ass, which is fine, he needs to do that. But F-Line has made it sound like that route checking has been re-reviewed and re-re-re-re-reviewed unto death. It's a known reality: there are two routes, period. We CANNOT give one up, even if we cannot yet find the will or the $ for the NSRL.
*ETA: If you go to the Schematic Design Report link over at the NSRL thread, you'll see there's like 100 feet of vertical distance to the roof of the potential NSRL tunnel. That's a fair amount of room to work with. I don't think the constraints I'm talking about even come close to precluding all high rise structures here. But it does preclude certain foundation options in favor of other foundation options. This is the point I'm getting at: this site has to be zoned from the bottom up, unlike everything else on the waterfront, which seems to start with shadows first.
