I would love to see an office building get converted into a school. I'm assuming if a field and gymnasium is a requirement, it would be an issue. Gymnasiums are a bit easier to deal with, and could be build above ground, but a playing field is tougher tom implement.
There are a few office buildings along 10th/11th ave that have good sized parking lots that could be turned into a playing field. This is one site that comes to mind which could be turned into a K-9 school with the adjacent lot to the west turned into a field and gymnasium. It's fairly central to everything and should easily be large enough to house K-9.
