Any idea when these will offically break ground?
KriterionBos -- This is Boston -- there is no way to know if they will ever break ground -- and that's ignoring the unusual dynamics of the COVID-19 Pandemic era
Having observed development in Boston / Cambridge since the 1960's many proposals which get to the stage of being approved -- still never happen at all
Go to Emporis and look at the table of skyscrapers in Boston -- there is a category and a color code for those proposed such as Menino's 1000 footer
Beyond the ones which never happen -- there are many which happen a decade or more after they first get reviewed - - sometimes because they are proposed so late in the Business Cycle that things stop for a while to wait for the next upswing -- such as anything proposed about 2008 which went on hold until 2015 or so
There is a special category of "on-demand" building -- being developed for an Amazon, Vertex, or a Google. This type of project has its own rules and its own timetable --- all of the pieces are in place and the process works in a well-oiled fashion
Outside of these -- Boston projects take time to move through the approval process -- the typical project [proposed during the good phase of the business cycle]:
Takes at least a few years from its first LOI [Letter of Intent], then formal filing, to being approved by the BPDA after going through changes to meet the BPDA reviews
Then it often spends time going through a couple of NPC [Notice of Project Change] on the part of the developer in response to changing market conditions
then it gets through all of the permitting needed from the City, MA and sometimes even the Feds
then it has to get financed [assuming things haven't changed too much since it was a gleam in the developer's eye]
All the above takes a year or more from the BPDA approval -- and then finally:
the digging, boring, demo, whatever actually begins
Go to the BPDA website and look at a major project of your choice -- you can see all this in excruciating detail
Or more instructively -- pick one of the projects on AB and start at post #1
