Section 4 4-2 Ramsey County Multijurisdictional Hazard Mitigation Plan | July 2012 4.2 Risk and Vulnerability Assessment Process The Multijurisdictional Hazard Mitigation Planning Committee conducted a comprehensive hazard, risk, and vulnerability assessment of Ramsey County. To develop effective hazard mitigation strategies, it is first necessary to identify and profile all hazards facing the community. A risk assessment is the process of measuring the potential loss of life, personal injury, economic injury, and property damage resulting from natural hazards by assessing the vulnerability of people, buildings, and infrastructure to natural and technological disasters. Several methods were used to identify risks to the community that included evaluating historical data from scientific and news media sources, soliciting opinion and experiences from participating jurisdictions and Ramsey County residents, and surveying risks identified in the State of Minnesota HMP that were pertinent to Ramsey County. Following the risk assessment, a vulnerability assessment was conducted. This analysis predicts the extent of damage that may result from a hazard event of a given intensity in a given area on the existing and future build environment. Determining the community’s vulnerability involved identifying the risk posed to people, property, and the environment. This also included identifying critical facilities that could be affected by each hazard. The following natural and technological hazards were identified: Hazard Justification for Inclusion Severe Winter Storms Frequency, previous incidents, county-wide hazard Severe Thunderstorms Frequency, previous incidents, county-wide hazard Tornadoes Frequency, previous incidents, county-wide hazard Lightning Frequency, county-wide hazard Extreme Temperatures Frequency, county-wide hazard Hailstorms County-wide hazard Wildfires Frequency, potential adverse impact Flooding Frequency, previous incidents Drought Previous incidents, county-wide hazard Rockslides Previous incidents Epidemics/Pandemics Previous incidents Dam/Levee Failure Potential adverse impact Terrorism Potential adverse impact Requirement 44 CFR 201.6(c) (2) (ii) The risk assessment shall include a description of the jurisdiction’s vulnerability to the hazards described in paragraph (c)(2)(i) of this section. This description shall include an overall summary of each hazard and its impact on the community. Requirement 44 CFR 201.6(c) (2) (i) The risk assessment shall include a description of the type, location and extent of all natural hazards that can affect the jurisdiction. The plan shall include information on previous occurrences of hazard events and on the probability of future hazard events.
