9 Executive Summary Executive Summary The is the first hazard mitigation plan developed by Dade County in conformance with the requirements of the Disaster Mitigation Act of Natural hazard mitigation is defined as actions or activities taken to reduce or eliminate losses resulting from natural hazards. The Dade County Natural Hazard Mitigation Plan is intended as a guide and resource for county and municipal governments, public organizations, residents, and other community stakeholders that are interested in reducing the potentially disastrous effects of natural hazards on life and property in Dade County. The Plan was prepared and written with the participation of Dade County government and the following Dade County communities, school districts, and special districts: Arcola, Dadeville, Everton, Greenfield, Lockwood, South Greenfield, Dadeville R-II School District, Everton R-III School District, Greenfield R-IV School District, Lockwood R-1 School District, Dade County R-IV Rural Fire Protection District, and the Dade County Nursing Home District. An open planning process was conducted in the development of the Plan. The public and other community organizations and private sector entities were invited to participate and assist in the planning process. The Plan profiles of ten natural hazards which threaten lives and property in some, or all, of the participating jurisdictions. These hazards include Tornado, Severe Thunderstorm, Flood, Severe Winter Weather, Extreme Heat, Drought, Wildfire, Earthquake, Dam Failure, and Sinkhole. All hazards were evaluated with regard to previous occurrence, probability and severity of future occurrence, and the potential impact on each jurisdiction. A comprehensive mitigation strategy was developed through the consideration of potential hazard threats, current capabilities, and the potential resources available to mitigate the effects of the identified hazards. The goals of this mitigation strategy are: Goal 1: Protect citizens from injury and loss of life. Goal 2: Preserve and maintain property, infrastructure and the county s local economies. Goal 3: Ensure continued operation of government and emergency functions during a natural hazard event. The Plan has been formally adopted by two of the participating school districts and will be adopted by the remaining participating jurisdictions following approval of the Plan by the Federal Emergency Management Agency (FEMA). Participation in, and formal adoption of, the Plan qualifies a jurisdiction to apply for FEMA pre-disaster mitigation grants and the mitigation portion of post-disaster mitigation grants. The Dade County Natural Hazard Mitigation Plan will be updated in five years, as required by FEMA. It will be evaluated and maintained on an annual basis prior to this update. vii
