Abstract: The level of exposure to the impact of natural and man-made hazards of the main critical facilities at Grand Cayman (GC), Cayman Islands, was determined using the methodology developed by the National Oceanic and Atmospheric Administration Coastal Services Center. Previous studies identified hurricanes as the most important natural hazard for GC. However, other hazards include earthquakes, tsunamis and explosions or leaks of fuel storage tanks. Our results indicate that: (1) About 82% of the emergency response infrastructure, 95% of the government facilities, and 85% of the utilities have a level of exposure from low to moderate; (2) only 12% of all identified critical facilities at GC are highly exposed; (3) large explosions or leaks of the Airport Texaco Fuel Depot, the local fuel pipeline, and the Home Gas Terminal could impact nearby critical infrastructure. The facilities identified with a high level of exposure are as follows: the Bodden Town Clinic and Police Station, the West Bay Fire Station, the Georgetown Dock and Port, and the Esso and Texaco Fuel terminals. Most portions of the coastal roads are moderately exposed to natural and man-made hazards. The most exposed sections are four short segments of the road system located along the North Sound, Little Sound and Eastern West Bay area. In some cases, the high exposure of critical facilities stems from their location on the coastline. In other cases, however, adequate policies to either protect or to relocate these facilities would help to reduce their level of exposure to both natural and man-made hazards.
