I'll preface this by saying I realize this is just pie in the sky fantasy talk, but if Peden were to be rebuilt to a capacity somewhere around 30K-35K while maintaining its current shape (but properly connecting the endzone pieces of course) would there be enough room between the east side stands and the IPF to add a second tier at a later date?
Depending on how big you want that section to be, the light poles would need to be moved. As it is now, it looks like there is about a 25 foot gap between the end of the east stands and the light poles, which should be enough room to add a second deck. The architectural question I have is how would people get to that second deck? At the bottom of that gap is a driveway for deliveries, buses, etc.
I've always thought that if they want to add to the east stands, the current back walls could be demolished and another 12-15 rows could be added before the light poles are reached.
