Kennie, Kennie, Kennie.... you ARE talking about the planned urban core. In the future it will stretch from Hawaii Kai to  Waianae and along H2 up to Wahiawa. 

High density development is projected in that area. We may need room for an extra million people on this island. 

This planning started about 20 years ago for a new 30 year plan just continues planning from the Arioshi administration for the original 30 year which plan emphasized change. 

The new plan emphasizes planning along ahapuaa boundaries for sustainability. With such a large expected population a simple disaster in Hawaii might lead to a holocaust if we are not sustainable. 

We need to move more farmers to Oahu. Another reason is that a distributed renewable power grid is needed. For that a smart grid is needed. But in the future we'll need more total energy - starting with transportation needs. We also need large renewable power plants. We need to start planning for climate change.
