According to the Federal Emergency Management Agency (FEMA), Flood Insurance Rate Map (FIRM), Panel Number 150001-0110D, the site is almost entirely within the floodway Zone AE (See Figure 2‑6). Areas within Zone AE are inundated by the 100-year flooding for which base flood elevations have been determined. Near the railroad right-of-way, the flood base elevation is 5 feet.
The island of ‘O‘ahu is not within the seismic zones, therefore no special construction requirements are required. Tsunami inundation maps show that the project site is not in the tsunami inundation zone.
