I'm not sure who is involved in the permit process. I'd guess that IHL or the State has some say in the matter as well as Oktibehha County. They could split the package and run with a Land Disturbance permit submission that would allow them to begin excavation and site work. That would certainly provide evidence that the project really is going to happen.
They need to at least finalize the design and plaster the images all over the large banners that hang from the stadium. They could even place renderings throughout the stadium showing how certain areas will be affected. I hope they work this expansion to maximum effect for future ticket sales, donations, recruiting, etc..</p>
