The City and State continue to play whack a mole with the homeless.  There needs to be a places set aside to where the homeless can go to camp.  In conjunction with this, there has to be very tough enforcement on those that
continue to chose to live on the public streets. And of course the existing shelters for the homeless need to be supported and outreach services expanded.  In addition true low income subsidized housing projects need to be 
constructed by private builders.  The irony is that there are many condo's being build or planned in the urban core of Honolulu, but they  are high end apartments targeting the rich both here and abroad.
These developers will not build so called "affordable units" as there is less profit to do so and the  demand especially from abroad continues to be very strong and that will not change.
