You may have a lot of people who just want to take a workshop her and there without actually going to college. That's fine as long as there are some students working toward degrees. Distance learning on video and the web need to be accounted for in the plan. Student Services is a significant part of the campus. I'm lumping quite a few things in this area that might or might not be the way they finally end up.
Admissions is important.
Even if you maintain an open admissions policy you still need to have some kind of application for students and some process for acceptance. You will also need a financial aid process. Even now when workshops are funded by particular sources there should be a mechanism that shows that some of the funding went to student tuition. This would tell people how you intend to help students who have trouble. Counseling is an area that needs some attention.
