If you use the 300-meter definition of a supertall, the only place in Back Bay you could build that high would be between Hynes and Mass Ave; maybe 40 or 50 Dalton would be candidates.
Terminating at Ash st also gets you the benefits of 1) saving a bunch of $$$ with an at-grade station and no need to worry about grade crossings through Reading center
2) great location for TOD and even an out-of-the-way park + ride right off 128
Perhaps I worded it incorrectly. What I meant was more "density needed to be cost-effective", not "density needed to support".
Regardless, what I said before still applies:
Now, this is an old analysis with what I could only describe as an opaque methodology and suspect rigor, but it has some...
Specifically around station areas (not including peripheral industrial, low-density commercial, parks, etc.) its definitely closer to 20k if not above. But yes. At modern construction costs, it could possibly be difficult to justify building parts of even some of the existing lines if they...
Much of that development has been south of Rt 2 or west of 128. Downtown Lexington is nowhere near the 30k-40k/square mile population density needed to support heavy rail and won't ever be.
Adjusting the outer lanes of Rt 2 would be enormously expensive because of all the exit/entrance ramps and frontage roads. And all that for... a multi-use path directly adjacent to a high-traffic road? Ew.
Talking about orange line reroutes had me wondering: what if back in the 70s and 80s the T had dumped what money it spent on RLX to Alewife and Braintree and OLX to Forest Hills and Oak Grove into a new S-bahn-like(?) system, utilizing the OL tunnel through downtown and rail ROW that was yet to...
This is actually pretty huge. The street tree density bonus (which is a very reasonable 5ft easement) essentially makes three-deckers allowed by right everywhere.
I'm a fan of the parking minimum elimination too, but honestly, I don't think it will be consequential given the max floor plate...
I am curious to see how the language of this will be designed to interact with the Starter Homes ballot initiative, because that one explicitly singles out single-family homes as what would be allowed on 5000sqft lots, not duplexes.
