Phase 1 – 2015
This project will document the informational gap that currently exists for the Community and visitor population on recommended evacuation routes from the coastal areas. In addition to providing recommended evacuation routes, it will identify locations of refuge areas, shelter locations, and traffic signage which is not currently available. Tsunami Evacuation Zone Boundary signage will also help to better establish the minimum safe evacuation distance from the coastal shoreline which also does not currently exist.
Phase 2 – 2019
Following on the heels of the completion of an emergency evacuation plan for the geographic areas of Ewa, Kalaeloa, Ko Olina, Nanakuli, Maili, Waianae, Makaha, Mokuleia-Waialua, Waimea-Sunset Beach, Kahuku, Laie, Hauula, Kaaawa, Waikane-Waiahole, Kahaluu, Heeia, Kaneohe, Kailua, and Waimanalo, this Phase 2 study would include the remaining coastal areas not included as part of the Phase 1 study. The plan will include identifying refuge areas and shelter facilities as appropriate. If private road access will be required, the study will identify coordination/collaboration requirements. Additionally, the plan will also have a GIS evacuation route/tsunami boundary signage plan for Oahu using standard approved Manual of Uniform Traffic Control Devices (MUTCD) and NOAA/FHWA signs, and establish policies and procedures for tsunami-ready multi-story buildings in urban areas along the southern coast of Oahu for vertical evacuation.
