Kirk Caldwell, a candidate for Mayor of Honolulu, supports rail transit but calls for a review of the design process for the Phase IV/City Center stretch. He asks that community input be considered to find more appropriate and cost-saving design options. He also calls for a peer review by independent experts. This could allow new HART CEO Dan Grabauskas to avoid decisions made before him and make improvements to address legitimate community concerns, especially in historic areas. Examples of building rail better include reflecting neighborhood character in station design, beautifying transit corridors, and advancing transit-oriented development planning.
