Multi-Hazard Mitigation Plan: 18. Risk Assessment

Home

Chapter 18:Risk Assessment The Army has an airport at Pohakuloa training area, with a runway 3600 ft long. It is of little value for supply or evacuation due to the remote location and short runway combined with the elevation of 6000 ft. Airline fuel is loaded only in Honolulu. Fuel for smaller aircraft and helicopters could become a problem when tank trucks are emptied if the storage tanks are unable to refill them. There are about eight small (ranch and crop duster) airstrips around the island. Civil Defense has a map of them, as they are no longer shown on aviation maps. 18.1.10.1.3 Roads and Bridges The major arterial highway system circles the island with a mix of State and County jurisdic- tion (see Figure 18-11). However, during emergency evacuations, the County police control all State highways or County roads, assisted by the Department of Public Work's pre-planned barricade system. Barricade locations are shown in the tsunami evacuation maps. If a bridge or crossing on a State highway is damaged or threatened, the County will respond during the emergency to determine whether to close and to designate alternate bypass routes. During the recovery phase, the State and County cooperate in clearing and restoring roads around the is- land. 18-27 Hawaii County Multi-Hazard Mitigation Plan
