I'll confess, I don't really understand what a stadium and 'housing' have to do with one another?
I wouldn't think living near a stadium, with the traffic issues it would entail, having thousands of strangers traipsing around multiple times a week, the noise... would be especially appealing. I just don't get why someone paying billions to build a stadium also has to build 'affordable housing' and what those two things have to do with each other. It seems like a fairly lame attempt to show that 'good' will come to the community from the stadium. The 'good' that comes to the community when a stadium is built is money. Revenues and associated benefits to local businesses is the real motivator for cities to host an NFL stadium. The 'housing' stuff is just political fluff imho, as is the idea of keeping a 'low' profile.
It's a stadium. It's going to be huge. Frankly, I would want that stadium to be seen for miles, and like RFK to become the latest in iconic DC landmarks. The idea that you're going to blend in a gigantic sports venue 'into the surrounding community' - it's absurd.
Maybe the entire stadium should be built underground so there's room for more affordable housing on top of it
