It is. I remember reading 15 feet a couple of weeks ago. It will be interesting to see how they accomplish that, especially since it's likely that they'll bring in a natural surface.
in the past I've seen several venues operate where they use pallets to create the base and the sod across the pallets, it allows for drainage away from the turf and helps act like soil to soften the ground instead of rolling sod on concrete. In this case i would imagine they'll use stage decking to build up the height since its easy to level, and then pallets across the deck.
I would imagine then they'll replace close to 25-30% of the sod after each game
