2018 Mitigation Plan Update Morrow County – Countywide All Natural Hazards Mitigation Plan EXECUTIVE SUMMARY The Morrow County Emergency Management Agency/Office of Homeland Security spearheaded this effort to complete and update a comprehensive countywide Mitigation Plan. Their dedication to this mitigation planning effort is seen in the results of having full participation from the County as well as the incorporated jurisdictions. Morrow County is subject to natural hazards that threaten life and health and have caused extensive property damage. To better understand these natural hazards and their impacts on people and property and to identify ways to reduce those impacts, the County’s Emergency Management Agency (EMA) undertook this countywide Mitigation Plan. Most mitigation activities need funding. Under the Disaster Mitigation Act of 2000 (DMA2K, 42 USC 5165), a mitigation plan is a requirement for Federal mitigation funds. Therefore, a mitigation plan will both guide the best use of mitigation funding and meet the prerequisite for obtaining such funds from the Department of Homeland Security’s Federal Emergency Management Agency (FEMA). This Mitigation Plan meets the criteria as set forth by FEMA in the DMA2K and provides a community with a “comprehensive guide” for future mitigation efforts as they relate to the hazards that affect their community. The initial Mitigation Plan was developed under the guidance of a Core Group of individuals from communities and agencies throughout Morrow County. The Core Group met four separate times during the planning process to discuss the hazards that affect the county, the problems associated with these hazards, potential mitigation alternatives to minimize the effect of these hazards and goals that they would like to see achieved within the county. The update of the Mitigation Plan was developed under the guidance of a Mitigation Planning Committee formally comprised of the County Emergency Management Agency Director, a Mitigation Planning Consultant, and county planners and leaders. Throughout the process of updating the County Plan, these individuals were in direct contact with other County officials, community representatives, and State and local entities to gain their feedback on issues relating to the update. Morrow County has experienced many natural disasters in the past one hundred years. The Core Group, as well as the Mitigation Planning Committee, evaluated these hazards and chose to address the following hazards based on their impact on human health and property damage: Wind Events (Strong and High Winds), Tornadoes, Severe Winter Storms (Blizzards, Heavy Snow, Cold/wind chill, Extreme Cold and Ice), Severe Summer Storms (Thunderstorms, Lightning, and Hail), Flooding, Dam Failure, Excessive Heat, and Drought. With the hazards identified, a vulnerability assessment was completed for Morrow County. This assessment reviews how vulnerable the County is to property damage, threats to public health and safety, and adverse impact on the local economy. It also evaluates the location and likely damage to critical facilities and other structures from different scenarios of strikes by the eight (8) hazards. The culmination of Morrow County’s initial Mitigation Plan was an Action Plan for the communities to use to track progress on the implementation of their mitigation alternatives. The updated Plan incorporates any needed modifications, deletions and additions to the Action Plan. i 2018 Mitigation Plan Update Morrow County – Countywide All Natural Hazards Mitigation Plan TABLE
