Identify and analyze project cost share options. Submit mitigation project applications annually at a minimum. Metropolitan Nashville - Davidson County Mitigation Strategy Multi-Hazard Mitigation Plan Page 5-4 April 2010
IDENTIFICATION OF MITIGATION MEASURES This Multi-Hazard Mitigation Plan was originally created in 2005. In 2009, the CPT reviewed and agreed to continue to adopt the original mitigation measures and recommended actions as noted in this section, with slight edits and updates as noted. Following the goal setting meeting, the CPT conducted a brainstorming session to generate a set of viable alternatives that would support the selected goals. Each CPT member was provided with the following list of categories of mitigation measures: • Prevention; • Property Protection; • Structural Projects; • Natural Resource Protection; • Emergency Services; and • Public Information. Potential mitigation measures within each of the six categories were presented to the CPT. (see Appendix A). A facilitated discussion examined and analyzed the alternatives. Then, with an understanding of the alternatives, the CPT generated a list of preferred mitigation actions to be recommended. Similar to the goal-setting activity, the CPT included all previously recommended mitigation actions from existing Metro mitigation plans in its review. This process reinforced Metro’s use of the Multi-Hazard Mitigation Plan as an umbrella document for all exiting mitigation plans mentioned in Section 3. Thus, this plan puts forth existing recommendations that are still to be implemented in addition to the new recommendations that resulted from the CPT’s detailed Risk Assessment process. This plan serves as an update to the existing mitigation plans by identifying the recommendations from previous plans that have already been implemented and by reprioritizing those that remain. Once the old and new mitigation actions were identified, the CPT members were provided with decision-making criteria to prioritize the recommended actions. FEMA’s recommended “STAPLE/E” criteria set (social, technical, administrative, political, legal, economic, and environmental criteria) was utilized in order to help decide why one recommended action might be more important, more effective, or more likely to be implemented than another. With these tools, the CPT then undertook an exercise to prioritize the recommended mitigation measures. CPT members were provided with colored “stars”: three red, three blue, and three green. Each color represented either high, medium, or low priority with regard to the importance, and each color was assigned a corresponding value (high = 5 points, medium = 3 points, and low = 1 point). CPT members then voted for their preferred mitigation measures by placing their “stars” on specific mitigation Figure 5.1 Priority “Stars” Metropolitan Nashville - Davidson County Mitigation Strategy Multi-Hazard Mitigation Plan Page 5-5 April 2010
