From a beginner standpoint, I could very easily imagine some training/skills areas on flat terrain. Long, straight skinnies that are not too high. Some basic berms, log piles, and rock gardens as well. By putting these features on flat-ish terrain and with plenty of room, new and inexperienced riders can learn how to handle them at both decreased risk and pressure. I know it would be some work, but building a jump line and/or another pump track would be pretty cool too.
I think part of the success of the larger parks and biking destinations is due to their ability to provide for riders of all levels. As much as we love trails with big downhills and jumps and tight, off-camber turns, you gotta start somewhere.
