The only "personally" that matters here is Medford. Please re-read Vagabond's post. This is a municipality with a limited commercial tax base, and limited internal planning ability. If they're going to shoot big for anything, it has to be mixed-use as a requirement because commercial is where they're hurting most. You're not going to get mixed-use at all in a car-free cul de sac. Degrees of aB agreement/disagreement on whether waterfront apartment towers would even draw car-free on the Wellington slab are moot; that's flat-out not Medford's priority vs. the degree-of-difficulty. They'll choose any slab that can slug equal commercial-use weight first, second, or third over that one. The degree of difficulty required to execute anything properly on this slab is prohibitive for a low return at not the commercial return they most desperately need. And they'd have to do it with the T grabbing its joint share of the property taxes in a way more convoluted property agreement, which helps the city far LESS with their tax base problem. This is why they're behind the T on the bus yard swap that frees up the entire Fellsway slab for full-blown mixed-use returning full-blown municipal taxes and which would allow for street gridding to all 4 sides of the slab. It's not even a contest for Medford. Fellsway is #1 with a bullet for the ability to plan it 'clean' and full-gridded...redevving the ailing strip malls north and west of the Circle a #2 (slightly more complicated and patchwork land flipping).
Context like this is why you can't look at this with 2D SimCity mentality. This isn't Boston where the planning machinery is so vast that any misfit slab like this gets shoehorned equally valuable for any purpose. Medford's got a five-alarm priority for developing at least a 50/50 or higher ratio of commercial to residential/other on any big production. This slab does not support that. They thus far have expressed negative interest in going there because it's too many complications for too little upside to the tax base they most need to stoke all amid their limited bandwidth as a city for taking home-run swings. Their interest in it has solely lined up behind the much bigger state enacting a land-swap domino fall that serves up extremely better-access parcel that they can work with. That's their stated max bang-for-buck priority based on what bandwidth they have to mount these efforts.
We can either acknowledge that as the guiding force in Medford...a city which is developmentally unlike the CBD...and contour with it. Or we can double-down harder on SimCity fantasy, pretending their tax base needs aren't what they say they are, or inventing gigantic car-free 50/50 commercial narnias that don't exist in any Massachusetts--CBD or otherwise--that we're familiar with because eye-of-beholder decreed all waterfront...must...be...tall. Look, if this sidebar is springing forth from a Station Landing thread that's about real Medford-fitted mixed use, shouldn't it be contouring to the same realities in evaluation???
Right...and the T that just spent a mint redoing Wellington Yard is going to immediately re-space the tracks for bridge piers because of a low-margin real estate project that no one least of all Medford is asking for, which fucks up its Bus Facilities Master Plan, which fucks up its station egress traffic, and still doesn't fashion nearly enough of a grid on the malformed triangle.
Read all above. Can we please start treating the fundamental differences between these slabs on either side of the tracks and what they mean to Medford instead of taking ever more death-defying leaps trying to pound them to sameness? They're different. They SCREAM different on that whole Google overhead you posted to kick off this sidebar. Even if you wanted so very badly to build something there it's not going to be successful redev unless it's fitted to its surroundings. Giant kludged ramps in the sky over train yards aren't fitting it to its surroundings. These were crap kludges when Boston 2024 was so horny for the Widett Circle narnia...now we're importing them wholesale to a riverfront wedge in fucking Medford in direct antithesis to the city's dev priorities of a 'clean' gridded slab?
Seriously...stop this madness. The value proposition starts off way compromised both on access and supportable mixed-use ratios critical to lining up the city's support. You aren't going to fix that with tactical nuclear strike kludges. The stakes are way too low to Medford for that when better lands lurk on the other corners of Wellington Circle. All I'm seeing here is a lot of Medford's lack of pressing need for the Wellington slab being backfilled by over-the-top personal need that...it...must...be...because...[trails off]. Why must it be? Why must it be for you when it isn't for the actual city you wish would do it? Please answer that first before digging deeper into this fantasy.
