Looking at renderings and the construction camera available online (linked below), it appears that there will be an area along both the third and first baselines (extending from approximately the edge of the outfield grass to just past the middle of the outfield that will not be a berm, per se. Instead, it will be a terraced area so that fans can bring tailgating chairs and set them up on any particular level, which would likely be appealing to some fans.
I sat in a similar terraced area at an LSU @ Ole Miss game several years ago out in left field at Ole Miss' park, and it was a great time. Of course, at Ole Miss, where they have the whole baseball atmosphere figured out, that is set up in such a manner so that fans can bring their own coolers in and be able to sit out there and drink beer. The area was packed and lively (over 10k fans there that day). They also have a VERY lively student area in right field (believe Bama now has something similar).
And as others allude to in this thread, if UK wants to continue to enjoy large and lively student crowds for home games when the weather is cooperative, UK will need to have an area with unrestricted access or otherwise get creative to allow (or turn a blind eye to those who are not being idiots or being a danger) students to bring beer. This is not rocket science. Has been pretty cool to see UK get good crowds and create a very good atmosphere at baseball games.
For those who have not seen the construction camera, the following link should allow you to access same:
