To be sure, but along with thise very valid reasons, alot of the "slower" is because of Ballantyne. The new Mayor - whether Wilson or Burnley will be a big change - - I see both (for different reasons) being more of a wider spigot for dense residential construction going forward.
Pro-developer can be perjorative to much of the public. Say what you will about DeMaria (and yes, there are some valid questions), he is Marty Walsh-level pro-development and the pace of dense residential in Everett is impressive - even without a Golden Platter of a GLX being delivered to it in the past 5 years like it was to Somerville.
I'm interested to see what happens with Wilson or Burnley - - the other dynamic is how this all navigates with the changes in Washington.
