The most powerful force in the universe is inertia. Everyone knows how crucial Blue extension to Lynn/Salem is... yet here we are, years later, and where is the tangible progress? Rummaging through my post archive, I see my contributions (frivolous or otherwise) to this discussion are the following:
1.) April 2014--In the "Lynn Central Sq" thread, I submitted photos of
the parking lot adjacent to 1 Carey Circle in Point of Pines, the condo complex (not apartments, jklo), which appears to encroach on that ROW from the old Boston, Revere Beach & Lynn RR. When you're standing in the parking lot (as I did--my friend lived there at the time), it sure looks like encroachment--but (if I recall correctly) others then pointed out that there's probably nothing illegal that was done there with the development--the complex may crowd the ROW, but probably doesn't illegally encroach.
Anyway, my friend has long since moved out, but I suspect any NIMBYism-oriented politics at the 1 Carey complex will always be directed beachward, where the cachet is, versus on the ass-end, which is all industrialized with the Newburyport tracks, GE plant, 1A, incinerator, etc. [Which is to say, the periodic piping plover nesting site-related beach closures at Point of Pines drive must drive them absolutely ballistic.]
2.) November 2014--In the "Blue Line To Lynn" thread, I pointed out that Captain America [Seth Moulton] was making lots of noise, having just won the 6th district seat, about the Blue Line extension.
Six years later... victory in the 6th district still runs through Lynn, of course. So I don't see why Seth wouldn't still want to focus his infrastructure advocacy on Blue Line extension--perhaps especially because his North/South Rail Link stumping has fizzled-out so ingloriously? (so far at least)
Six years later ... water in the Rumney Marsh has risen another 20 mm due to sea level rise, with all the corresponding erosion/inundation that entails. What will it be like in
that giant tidal basin (I measure it as being approximately 3 square miles) when the
next Perfect Storm hits--when sea level is (at least) 50 mm higher than it was in 1991 when Marky Mark went down in the Andrea Gail?
(Yes, technically its in the lee of brave little Nahant--but ask the old-timers what it looked like in Lynn Harbor during the aforementioned storm--Nahant can only do so much...)
And remember, with a nor'easter driven storm surge, you'd have the catastrophic inflow--and then all of that piled-up water has to discharge eventually--and it might be exiting as the next storm-driven incoming high tide is entering--so how awful could that outflow be? (As it is, when it's regular high tide these days, by how many feet does the Newburyport line bridge clear the water in the first place?)
All of which is to say: I think a Blue Line to Lynn/Salem extension plan, assuming the infrastructure was as rigorously engineered as feasible for projected sea level rises, would be foolish without a retrofitting of the Newburyport line there, to make it just as resilient in the face of the Next Big One.
