You know, I'd be okay with the Brandywine development. I hope I'm not totally going against something I said in a previous post. If so, forgive me for changing my mind.
The Brandywine development would be right next to the Domain and, while not "downtown", it's growing and has a lot to offer within walking distance. The rail station will probably be moved to that area from Kramer if this were to happen. It's next to two major freeways for the metro, giving reasonable vehicle access as well, and I-35 as well as 360 aren't far away. Lots of living options in multiple directions for employees, and more for those seeking condos/apartments coming in that area in the near future. While I prefer the development on Riverside, this one could work.
That said, I still think Dallas has the Texas bid. Don't hate me.
