Included in the plan are the cities of Atkins, Belle Plaine, Blairstown, Garrison, Keystone, Luzerne, Mount Auburn, Newhall, Norway, Shellsburg, Urbana, Van Horne, Vinton and Walford, the school districts of Benton County and the rural unincorporated area. The cities of Atkins, Belle Plaine, Blairstown, Garrison, Keystone, Luzerne, Mount Auburn, Norway, Shellsburg, Urbana and Vinton had previously completed single jurisdiction hazard mitigation plans. An initial planning meeting for this plan was held on August 5, 2009 with subsequent Hazard Mitigation Planning meetings held on March 15, 2010 and November 1, 2010. The Benton County Board of Supervisors appointed a planning committee and Benton County Emergency Management Coordinator Scott Hansen was appointed project lead. The planning committee met on November 1, 2010 and took official action to approve the plan. In addition, 11 individual community meetings and 6 meetings were held with Benton County organizations. Twenty-six hazards were identified by the committee, through community meetings and past mitigation plans as pertinent to Benton County. The hazards, as they ranked from 1 through 26, included: Energy Failure 1 Transportation Hazardous Materials Incident 2 Highway Transportation Incident 3 Rail Transportation Incident 4 Structural Failure 5 Structural Fire 6 Communications Failure 7 Tornado 8 Thunderstorm & Lightning 9 Flash Flood 10 Grass/Timber/Wildland fire 11 River Flooding 12 Fixed Facility Hazardous Materials Incident 13 Windstorm 14 Severe Winter Storm 15 Air Transportation Incident 16 Cyber terrorism 17 Human Disease Pandemic 18 Pipeline Transportation Incident 19 Hailstorms 20 Animal/plant/crop disease 21 Agro-terrorism 22 7 BENTON COUNTY MULTI-JURISDICTIONAL HAZARD MITIGATION PLAN 2011 Bio-terrorism 23 Conventional terrorism 24 Extreme Heat 25 Chemical terrorism 26 Criteria used to establish this list and ranking included historical occurrences, probable future occurrences and potential populations and property that would be affected. The committee also developed broad-based goals to be accomplished with this plan. The goals are: 1. Improve the quality of life for Benton County residents by mitigating potential hazards. 2. Take steps to mitigate the probable negative consequences that may occur in Benton County as a result of natural and human caused/combination disasters. 3. Identify potential funding sources needed to accomplish identified mitigation projects. 4. Protect the health and welfare of Benton County residents and properties in Benton County by enhancing the training and capabilities of all first responder organizations. 5. Developing capabilities to return to pre-disaster or improved conditions as soon as possible after a disaster occurs. 6. Assist businesses and industries to reduce the impact of hazards in order to ensure economic viability of Benton County. 7. Compliance with NFIP requirements. In response to these goals and the vulnerability assessment conducted for each hazard, 69 mitigation measures were identified and profiled. Of these 69 mitigation measures, 31 were applicable to all communities (including Benton County un-incorporated) and 9 were applicable to all hazards.
