<br />RISK AND VULNERABILITY ASSESSMENT <br />Ramsey County Multijurisdictional Hazard Mitigation Plan | July 2012 4-3 <br />Hazard Justification for Inclusion <br />Hazardous Materials Spills Frequency, previous incidents, county-wide hazard <br />Energy/Fuel Shortage Potential adverse impact <br />Power Failure Frequency, previous incidents, county-wide hazard <br />Aircraft Accidents Potential adverse impact <br />Invasive Species Potential adverse impact <br />Civil Disturbance Previous incidents <br />Critical Facilities and Infrastructure Loss County-wide hazard, potential adverse impact <br /> <br />The following hazards were not profiled in this plan due to geographic location, low occurrence, or low <br />potential for damage. <br /> <br />Hazard Justification for Omission <br />Avalanche Geographic Proximity <br />Coastal Erosion Geographic Proximity <br />Earthquake Low occurrence, Low vulnerability <br />Expansive Soils Low vulnerability <br />Hurricane/Tropical Storms Geographic Proximity <br />Karst Topography Low occurrence <br />Sinkholes Low vulnerability <br />Tsunami Geographic Proximity <br />Volcano Geographic Proximity <br /> <br />The following information was included in each hazard profile: <br /> Hazard Identification. The Multijurisdictional Hazard Mitigation Planning Committee has identified <br />10 natural and 6 technological hazards that have consistently affected Ramsey County and its cities <br />and townships. These hazards were identified by using statistical data and records from a variety of <br />sources, including presidential disaster declarations, maps, and hazardous materials response data. <br />The lists of hazards are based upon frequency, severity, probability, potential loss, vulnerability, and <br />large-scale effects on Ramsey County. <br /> Profile of Hazards. Each hazard will be profiled to explain how it will or has affected Ramsey <br />County. This will include areas prone to specific hazards and the effects that they have had on <br />Ramsey County infrastructure. It also includes previous events that have affected the County. <br /> Assets Exposed to the Hazard. The plan compares identified hazards with the inventory of affected <br />critical facilities and the effects on the population that is exposed to each hazard. This section will <br />also include a vulnerability assessment for future development, such as schools, water and waste <br />treatment facilities, and other critical infrastructure.
