Community garden set up questions

As luck would have it, our neighborhood has been working on putting a community garden in very close to our home! We are just getting started, and are having our first big planning meeting this weekend. What I'm wondering is how much, if anything, are you charged for your plot? Folks are flinging numbers around like $1 or $1.50/ft and I'm just trying to figure out how the compares to other places. To get an idea of the location, it's in the Atlanta metro area, and they put in raised beds with no nearby water source than a rain barrel and a polluted nearby creek. The beds are put on solid clay mixed with garbage (it was an old unofficial dumping ground) on top of asphalt! They tried to amend the soil by putting in not-fully cured manure. We're really excited to participate, but it's going to require a lot of elbow grease. Any help/tips/advice welcome!
