There are a least 1/2 a dozen advertized medium and mega sized planned projects in the area. The majority are ridiculously un-feasible. 1 on the west side has been abandoned leaving the local contractor holding the bag, liable for un-paid construction costs.
There was a master plan developed, though not entirely detailed, far from perfect, it did however identify areas deemed as high and low density, and zoning. It was never followed through or Gazetted. To bad, these big projects in these areas would have never even been considered if this plan was followed.
