Figure 7-6. Severe Winter Weather Vulnerability of State Owned Facilities 
Wildfire State owned critical facility vulnerability to wildfire is widespread throughout the state (Figure 7-7). At least some counties in the all parts of the state demonstrate a significant state owned critical facility vulnerability. Many of these high scoring counties are more rural than high scoring counties for other hazards since larger tracts of forest land located in a county can lead to higher likelihood of wildfire. Figure 7-7. Wildfire Vulnerability of State Owned Facilities 
Dam Failure Counties with the highest state owned critical facility vulnerability to dam failure tend to be those with the highest number of high hazard dams located in that county (Figure 7-8). Figure 7-8. Dam Failure Vulnerability of State Owned Facilities 
Note: Dam failure hazards have not been spatially identified in North Carolina in terms of dam failure inundation zones. Since point locations for high hazard dams are available this information was matched with the location of state-owned buildings or facilities that are potentially at-risk to dam failure. North Carolina Emergency Management continues to coordinate with the Department of Environment and Natural Resources, Division of Land Resources to determine how and when meaningful data on dam failure inundation hazard areas may be developed, but this information is unknown at this time and will likely depend on future state and/or federal funding availability for dam failure hazard mapping. Drought Since the likelihood and severity of drought is roughly the same throughout the state, the state owned critical facility vulnerability is mainly driven by the number of state owned critical facilities located in each county (Figure 7-9. As such, it is noteworthy that county like Wake and Orange have the highest level of state owned critical facility vulnerability to drought. Figure 7-9. Drought Vulnerability of State Owned Facilities 
Geological Due to the variety of geological hazards that can impact the state, there is not particular area that shows significantly higher state owned critical facility vulnerability (Figure 7-10). However, generally counties in the western part of the state seem to score slightly higher on the overall geological state owned critical facility vulnerability. Figure 7-10. Geological Vulnerability of State Owned Facilities 
Tornado/Thunderstorm As the map below shows, counties in the central and eastern part of the state exhibit the highest state owned critical facility vulnerability to the tornado/thunderstorm hazard (Figure 7-11). This is driven mainly by the much higher likelihood that counties in these areas of the state will experience tornadoes. Figure 7-11. Tornado/Thunderstorm Vulnerability of State Owned Facilities 
State-Owned Assets Estimates of Potential Losses by HazardIn order to estimate potential losses to state-owned assets, “worst case scenario” results were produced to show the maximum potential extent of damages for those hazards. It is understood that any smaller events that could occur would likely create fewer losses than those calculated here. The determinations presented in this section with regard to vulnerability were developed using best available data, and the methodologies applied have resulted in an approximation of risk. For the hazards of Earthquake, Hurricanes and Coastal Hazards, Severe Winter Weather, Drought, and Tornado/Thunderstorm, all state-owned assets are considered to be at risk. In a worst-case scenario event for each of these hazards, it is assumed that all state-owned assets would be impacted and may incur substantial damage, or losses equal to or exceeding 50 percent of the exposed value. Thus, potential state-owned buildings losses are estimated at around $11.5 billion and transportation system losses are estimated at $62.5 for total potential losses to state-owned assets estimated at $74 billion. As specific state-owned asset location information as well as specific hazard location data becomes available, future plan updates may explore vulnerability and potential losses due to these hazards in more detail. It is difficult to estimate potential losses for site-specific hazards such as Flood, Wildfire, Dam Failure, and Geological Hazards because vulnerability and potential losses depend on the specific location of each facility in relation to the hazard area, and such data is not currently available. Only a small percentage of state-owned assets are likely to be located in these specific hazard areas, thus only a small percentage of the total exposure of these assets may experience losses due to these hazards. As specific state-owned asset location information as well as specific hazard location data becomes available, future plan updates may explore vulnerability and potential losses due to these hazards in more detail. ConclusionIn terms of total exposure of state-owned assets by hazard, all state-owned assets in North Carolina, valued at around $148 billion, are exposed to many of the major hazards that affect the state. These exposure estimates, used to calculate exposure of state-owned assets for each hazard as identified in this section, were determined using data provided by the North Carolina State Property Office and in using HAZUS-MH, FEMA’s loss estimation software tool.
