Hazard and Vulnerability Assessment Tool
Hazard and Vulnerability Assessment Tool 1. Risk assessment based determined by Risk = 100 x [(probability/3) x (Human impact + Property impact + Business impact + Preparedness)/(4 x3)] 2. Percent risk (0 to 100 percent) 3. Relative measure Higher indicates greater perceived risk 4. Interquartile range is the range of the middle half of responses 5. Smaller interquartile range indicates greater agreement among team members used to break ties
HVA Results Top 10 Perceived Risks 1. Automobile accidents 2. Tornadoes 3. Heavy snow 4. Thunderstorms 5. High straight-line wind
HVA Results Top 10 Perceived Risks 6. Lightning 7. Hail 8. Ice storm 9. Extreme cold 10. Blizzard
HVA Results Other Notable Risks Flooding 11. Stormwater 20. Riverine Hazard Material Incidents 12. Fixed Facilities 13. Pipelines 14. Roadways 18. Railroads
HVA Results Bottom Ten Perceived Risks 36. Fuel shortage 37. Large-scale food contamination 38. Dam failure 39. Lake flooding 40. Civil unrest 41. Correctional center incidents 42. Landslide 43. Land subsidence 44. Earthquake 45. Dust storm
Hazard Identification FEMA requires the plan to address natural hazards Examples: Drought, Flooding, Thunderstorms, Tornadoes The plan can also address human-induced or technological hazards Examples Hazardous Material Incidents, Transportation Accidents
