Hennepin County Hazard Mitigation Risk/Vulnerability <br /> W HAZARD RISK/VULNERABILITY ASSESSMENT <br /> A. Overview of Risk/Vulnerability Assessment <br /> An essential element of the Hennepin County Mitigation Plan is an <br /> analysis of hazards and the risk they pose. Hennepin County <br /> Emergency Preparedness has divided the county into sectors for <br /> planning purposes. Sectoring,is often used to separate a county into <br /> manageable segments based on local geography and other factors. <br /> Below are the following 5 sectors. <br /> B. Synopsis of Risk/Vulnerability Assessment <br /> Individual hazards were evaluated for each city in the Sectors. The <br /> City Emergency Manager completed a worksheet and evaluated each <br /> hazard's probability, magnitude, warning time, and effect on <br /> operations continuity for their jurisdiction. These worksheets were <br /> then evaluated by sector and tabulated. See Appendix B for <br /> worksheet example. <br /> The scale was 1-5 with 5 the worst case. The highest possible score <br /> was 20. The worksheet was adapted from the FEMA mitigation <br /> guidance and beta tested on the Lake Minnetonka area emergency <br /> managers. They made suggestions and clarifications that were <br /> incorporated into the final document. Numbers were simply added <br /> .horizontally to get the total score. <br /> Vulnerabilities were identified by the local emergency managers. The <br /> EMs looked at critical infrastructure that could be open to attack by <br /> either natural events or terrorist activities. The effect that the loss <br /> would have on the jurisdiction was also taken into account. Threat <br /> and vulnerability assessments done for ODP grant purposes helped this <br /> process along, although that focus was on weapons of mass <br /> destruction and terrorism. At this time, the likelihood of a natural <br /> disaster is considered higher than a WMD/terrorism event. Both, <br /> however, must be planned for. <br /> The map section provides additional general information on <br /> vulnerabilities. A 302 facility map, floodplain map, groundwater, steep <br /> slopes, bridges, and schools and daycare maps tell where vulnerable <br /> populations are located. The zoom feature in Adobe allows individual <br /> assets to be seen. Infrastructure, existing and future buildings, and <br /> critical facilities are too numerous to list specifically in a major <br /> metropolitan county context. The maps must be used as needed. <br /> i <br /> Tl•\V T-T...-1 Rial.Vnlnornhility AaaPCemnnt Inn <br />
