In my opinion, $200,000 isn't wealthy. That is more along the line of average to a little above average. However I do understand what you are saying but I do not understand the vauge comment of "the wrong side of 35." As for the slight to Roosevelt, I feel that's very uncalled for. A quick glance at a site like GreatSchools.net shows that GreatSchools give the school a 7 out of 10 and the parents rating on the site give it 4 out of 5 stars.

I think it's a misconception of that general area that sometimes make it seem worse than it really is.
And I don't think anyone is expecting everything like the example you gave, all suburban developments are different whether dense or not. However, the one thing that makes me believe this will be something worth wild is that the city of Windcrest is doing this and not some sprawl happy developer. Look at Converse and there Town Square that is currently under construction. It's fantastic.
