The planning for the area very consciously copied that of Orange County, California - Honolulu’s planners won accolades for their vision!   That vision was supported by the vast majority of our political representatives up to and including the very same Governors who later opposed it- John Waihee and Ben Cayetano.  As best I can tell, they reflected the political will of the time.  So when the Campbell Trust sold the land and D.R. Horton bought it, they did so under the reasonable expectation that it would be urbanized.   This was all baked into a political process that no one questioned at the time.  All this made the effort to fight Ho‘opili much more difficult.
