If you've been to or seen the Tacoma Dome, just picture the outside without the frilly dome paint. Same architects who designed the T-Dome designed the Walkup Skydome. HOWEVER, there's not nearly the same flexibility within the Skydome as there is in Tacoma.
Basketball attendance is abysmal considering their record the last few years. They are not in a good revenue position.
Mind you, there was a recently announced facilities plan.
They're planning a new arena (not a new stadium) near the Skydome. Total of $162 million in proposed improvements. Phase I is under way... the new turf is already laid.
Lots of work to go here... fund raising is the issue at the moment.
