First and foremost, parking areas and roads. After that, water distribution systems, privies and perhaps showers (hot if we can afford them, cold if we cannot). Donations of time, expertise and materials will be especially valuable at that time.

All plans for building beyond this minimum are speculation. Until we get the land and know the zoning, we will not know what buildings will be suitable or even if permanent structures will be allowed.

Finally, if we do not get the support of the populace for improvements, they won't be made.
