I blame the Arlington situation on unfortunate events, a belligerent owner and the city in that order. However, it was a unique and difficult situation for everyone to deal with. But even worse, like a black hole the problem has expanded, you can see the effect it has had on the nearby commercial spaces, three nearby spaces that used to be vibrant are now also empty. Understandable, as who would like to live or work next to such a dump?
It is frustrating that our current elected officials seem unable to deal effectively with so many problems. I do think the voters notice and hopefully will choose better in the next election. I think several smug, but less than competent politicians will be surprised by the voters response.
The BMO site has even a longer more convoluted history, part of which relates to the city's management of the LRT line construction (or lack of). Again everyone involved in this should be ashamed of themselves.
