Quickly looked at a few footprints of a few NFL stadiums and this site seems like it'd be a solid candidate. The new LA stadium is being built on 15 acres.
Portland's leadership would never go for it. They need more bike paths. A joint venture by Tualatin and West Linn off of 205 would work for a stadium, as well as a new commercial area. It's a dead zone right now.
I like the NFL more, but a MLB team would be >>>>>>>>>>>>> Imagine going to a game during the summer months warm nights, beer, baseball tickets are relatively cheap compared to the NFL and NBA, relaxing environment I want it so bad
Looking at the Lloyd Dist. masterplan, I think the P.O. site is perfect for many reasons - the area directly north of the RQ is being zoned as a future "parking district" directly across the broadway bridge from the site.
