It will be tough getting the permits unless they have already greased the city council and can get it done before the next election. The neighbors hate the stadium and if you tell them "hey bros, good news, now instead of 7 events per year bringing loud drunkards to your neighborhood you will have 30 events per year bringing loud drunkards to your neighborhood" it ain't gonna go over well.
Evanston has a massive pension underfunding problem and their plan to fix it about 20 years ago was to allow unfettered growth of the downtown area. The theory was that if they put up a bunch of towers they would boost tax collections and most of the people living in them wouldn't have kids in school so it would be just gravy. Well, two towers got built and then the NIMBYs turned over the city council and now it is virtually impossible to build anything over 12 stories.
This venue has the same potential to be the focal issue of the next election cycle.
