You may remember last year at a Council meeting the development application to remediate the area immediately behind the Narellan Town Centre. This is part of Elyard Gardens development.
To help you get a sense of what the development may finally look like I have brought together the three key documents including the original master plan. I can't find anything more recent at the moment but the three documents I have found are:
The original Elyard Garden Masterplan (2005).
DartWest submission to South West District Plan. (March 2017, 15.0m file - really slow loading because someone left layering on).
Camden Planning Proposal 2011. The most recent publicly available document and likely the most accurate. see Anexure A.
Hopefully these will help cut through the speculation to see what is actually planned.
