Xtream Arena | Coralville, IA - Official Website
Maybe I missed it, but I hadn't heard about Coralville Iowa as a potential expansion city for the ECHL until I listened to Sin Bin interview Comissioner Crelin the other day on their podcast. The comish said there is no ownership group yet, so not on their short term plans, and they are obviously busy dealing with Covid and trying to get this season off the ground, so haven't spent a lot of time working on it, but they do view it as a potential future market if the right ownership can be found.
The link above says it is a new 5100 seat areana that will host a college club team, local youth hockey, and hopefully either an ECHL or USHL team. Obviously nothing is going to happen until there is the ability to host live sports again, but one to watch for the future.
