Perhaps I don't have enough clout on this forum to say so, but I will anyway. This place is close to 50 years away from what it will be. You have North Point being developed, the Green Line being extended, Sullivan Square and then the rest of the stupid Assembly Mall being demolished and a regular street grid being established. Never mind river crossing upgrades, the casino, and hey, let's consider whether or not the gosh darn ocean is going to rise. This is going to be a VASTLY different place in 20-30, if not 50 years.
I think this a good start.
The problem with your 50 year theory is it helps to build a solid foundation first. Which would have been rapid transit to the area.
In 50 Years Biotech could consolidate or possibly blowout. It will definitely evolve. I'm just not sure the current developments in the Seaport will evolve.
Do you remember the old warehouses in Cambridge, Lynn, Fitchburgh were all the shoe factories went bankrupt and the warehouses sat for decades abandon?
The build-out in Seaport is a risk for the city of Boston in this area. This could fall like a domino if Biotech Blewout or a massive consolidation happened in the industry. And companies decided to scurry for cheaper rents back to Cambridge. I'm not saying this would happen but who would fill those Biotech Buildings if they became vacant? Not Ropes & Gray or the Financial Industry,
The Fallon buildings would need to be occupied by BLUE CHIPS to afford to maintain those types of buildings.
I like this comment "The monolithic superblocks" as datadyne claims:
Fallon and the City of Boston, BRA followed the Kendall Square Model which might not pan out the same for Boston in 50 years.
My point on Assembly Vs Seaport
Assembly is much more vibrant and active: More fun.
Seaport sucks--Remy's, LTK, Legals Roof Deck, NO ENERGY in this area at all except TRAFFIC and whole lot of walking to nothing.
Assembly Instant MBTA access right into the core of the fun.
Assembly was a good development: I'm not saying EPIC but it does feel like a movie studio.
The city & state should have built a stronger Transit Infrastructure in this area then build off that. BIG MISTAKES in the Long-term that are very costly for Boston concerning the Seaport Development.
