3 Risk Assessment

3 RISK ASSESSMENT 44 CFR Requirement §201.6(c)(2): [The plan shall include] A risk assessment that provides the factual basis for activities proposed in the strategy to reduce losses from identified hazards. Local risk assessments must provide sufficient information to enable the jurisdiction to identify and prioritize appropriate mitigation actions to reduce losses from identified hazards. The risk assessment process identifies and profiles relevant hazards and assesses the exposure of lives, property, and infrastructure to these hazards. The goal of the risk assessment is to estimate the potential loss in Vanderburgh County, including loss of life, personal injury, property damage, and economic loss, from a hazard event. The risk assessment process allows communities in Vanderburgh County to better understand their potential risk to natural hazards and provides a framework for developing and prioritizing mitigation actions to reduce risk from future hazard events. A Multi-Hazard Mitigation Plan was completed for Vanderburgh County in September 2004. Therefore, this risk assessment is an update to the risk assessment previously prepared. There are, however, several improvements: 1) Hazards to include were evaluated and refined; 2) HAZUS-MH MR5 and parcel data provided by the HMPC was utilized to determine assets at risk; and 3) HAZUS-MH MR5 results assessed vulnerability and loss estimates for earthquake, flooding, and levee failure. The risk assessment for Vanderburgh County and its jurisdictions followed the methodology described in the FEMA publication 386-2, Understanding Your Risks: Identifying Hazards and Estimating Losses (2002), which includes a four-step process: Identify Hazards Profile Hazard Events Inventory Assets Estimate Losses This chapter is divided into four parts: hazard identification, hazard profiles, vulnerability assessment, and Summary of Key Issues. Section 3.1 Hazard Identification identifies the hazards that threaten the planning area and describes why some hazards have been omitted from further consideration. Section 3.2 Hazard Profiles discusses the threat to the planning area and describes previous occurrences of hazard events and the probability of future occurrence. Vanderburgh County, Indiana 3.1 Multi-Hazard Mitigation Plan DRAFT Section 3.3 Vulnerability Assessment assesses the County‘s total exposure to natural hazards, considering critical facilities and other community assets at risk, and assessing growth and development trends. Hazards that vary geographically across the planning area are addressed in greater detail. This section includes steps 3 and 4 from above. Section 3.4 Summary of Key Issues provides a summary of the key issues or problems identified in the Risk Assessment. 3.1 Hazard Identification Requirement §201.6(c)(2)(i): [The risk assessment shall include a] description of the type…of all natural hazards that can affect the jurisdiction. 3.1.1 Disaster Declaration History One method used by the HMPC to identify hazards was to examine events that triggered federal and/or state disaster declarations. Federal and/or state declarations may be granted when the severity and magnitude of an event surpasses the ability of the local government to respond and recover. Disaster assistance is supplemental and sequential. When the local government‘s capacity has been surpassed, a state disaster declaration may be issued, allowing for the provision of state assistance. Should the disaster be so severe that both the local and state governments‘ capacities are exceeded, a federal emergency or disaster declaration may be issued allowing for the provision of federal assistance. The federal government may issue a disaster declaration through FEMA, the U.S. Department of Agriculture (USDA), and/or the Small Business Administration. FEMA also issues emergency declarations, which are more limited in scope and do not include the long-term federal recovery programs of major disaster declarations. Determinations for declaration type are based on scale and type of damages and institutions or industrial sectors affected. Table 3.1 lists federal disaster declarations through FEMA received by Vanderburgh County. Each of the disaster events affected multiple counties; estimated damages reflect total losses to all counties.
