2010 Metro Mitigation Plan

Recommendations

Info

4. MWS has prioritized Capital Improvement Projects as outlined in the multiple Stormwater Basin Plans; 5. MWS has prioritized watersheds throughout the County for preparing/updating Basin Plans; 6. The IRC Building Codes contain seismic and design wind elements; 7. Residential plan reviews are performed on complex designs; 8. The NPDES water quality requirements may offer an opportunity to coordinate flood warning capabilities and stream gauging; 9. OEM has recently updated the severe weather warning siren capabilities of the community with 71 sirens; 10. Public information could be made available to inform residents about the risks of hazards (earthquakes, floods, and tornadoes, predominantly) and appropriate risk reduction actions that they can undertake; and 11. Metro does not support flood protection and retrofitting as standard solutions for residential flooding problems.

GOAL SETTING The analysis of the three components of the Risk Assessment identified areas where mitigation improvements could be made, providing the framework for the CPT to formulate planning goals. Each CPT member was provided an alphabetized list of possible goal statements. In addition, each CPT member also received a list of goals from other community plans that have had public input and review and have already been formally adopted by Metro. This information was provided to CPT to ensure that the Mitigation Planning Goals would be in concert, not in conflict, with other existing community priorities. CPT members then each received three index cards and were asked to write what they felt would be appropriate goals for this plan using the information provided as a guide. The CPT members were instructed that they could use, combine or revise the statements provided, or develop new ones. The goal statements were then attached to the meeting-room wall, grouped into similar topics, combined, rewritten, and agreed upon. Some of the statements were determined to be better suited as objectives or actual mitigation projects, and were set aside for later use. Based upon the planning data review, and the process described above, the CPT developed the final goal statements listed below. None of the final goal statements are the same as those provided on the alphabetized list. The goals and objectives provide the direction for reducing future hazard-related losses in Metropolitan Nashville - Davidson County. GOAL #1: Objective 1.1: Objective 1.2: Objective 1.3: Objective1.4: GOAL #2: Objective 2.1: Reduce exposure to hazard related losses for existing and future development. Strengthen the existing flood hazard mitigation program. Protect critical facilities, utilities, and infrastructure. Improve the coordination of severe weather mitigation actions. Develop a coordinated set of mitigation actions that address geological hazards (earthquakes, sinkholes, and landslides). Promote awareness of hazards and vulnerability among citizens, business, industry and government. Develop a seasonal multi-hazard public education campaign to be implemented annually.
