Aloha John.  I absolutely agree that most development should be concentrated in the PUC.  For years I led the Sierra Club fight against Koa Ridge and Ho‘opili.  We went all the way to the Supreme Court.  It cost the developers millions.  That wasn't our purpose.  We don't want to make housing more expensive. We want housing to be built in the right place to stop suburban sprawl.  The Ho‘opili development should have gone in Kapolei and the Hono‘uli‘uli farmland -the best in the state- should have been left alone.  As I understand it, other than the misbegotten developments in Hono‘uli‘uli, the prime areas for TOD are Iwilei, Kapalama and Kalihi.  If so, I have absolutely no doubt that the residents of affordable rentals built in those areas will use rail, so long as it doesn't get forced to become an at-grade trolley that will get clogged in traffic. Finally, the only way to deal with our housing & homeless crisis is to build a lot more of it - in the PUC, along the rail corridor.
