The 30 Acres guys have been campaigning and fund raising for years to get a park built. Looks like it has paid off. It is getting built in Robertson Park. It has been designed in conjunction with Gravity. They are the main contractor although from the sounds of it some of the work may be sub contracted out. Anyway with Gravity at the helm it should turn out good. The plans look good. Check out the thread on the forum to see the plans:
The build has started already and they are aiming to be finished by February.
