There is a rather large piece of land in between USJ3A & 3C along Persiaran Setia that is zoned as recreational land. Currently its a semi-forest, with no development planned. There was plans to build a hockey ring and a few other items just before the 2008 elections, but has since been scrapped. 

My considerations are:
1. Land being left idle is dangerous, as we have seen in the pass ownership can suddenly pass on to a developer. 
2. Subang Jaya, especially USJ - there is very little recreational choices. Besides shopping malls, and the little playgrounds we have in our neighbourhood, really what else is there for one to do during the weekends, off days? 

Moving forward, there are a few options
1. Maintain the area as a green reserve. Lets the jungle like trees remain
2. Build a park - something like Subang Ria, without the lake. Jogging track, picnic gazebos, bbq pits, etc 
3. Build something cultural there. 
4. Sports complex - Olympic size pool (we don't have one in subang jaya), tennis/squash courts, etc
5. A mix of the above, or something else. 

This is a long term plan. But all long term plans start somewhere, and I'd like to get the ball moving on this one...
