2010 Metro Mitigation Plan

Recommendations

Info

PROMULGATION STATMENT Date: TBD To: Metro Departments and the Citizens of Metropolitan Nashville and Davidson County. The Metro Nashville-Davidson County government continues to work toward ensuring the safety and well-being of citizens and property against hazards that have the potential for causing damage and/or loss of life. It is imperative that local government agencies, as well as the citizens at large make plans to effectively mitigate against the results brought about by the occurrence of such events. Accordingly, it is prudent to take appropriate steps to lessen the potential effects of such events or to eventually prevent their occurrence altogether. Reviewed and approved at the local, state and federal levels of government, the 2009 Metro Nashville Natural Hazards Mitigation Plan is one of many mechanisms through which these goals can be accomplished. By virtue of the powers and authority vested in me by the Metropolitan Charter and the Constitution of the State of Tennessee, and in accordance with the provisions of the Tennessee Code Annotated and the federal Civil Defense Act of 1950, as amended, as Mayor of Metro Nashville-Davidson County, I hereby promulgate and issue, effective this date, the Metro Nashville-Davidson County Natural Hazards Mitigation Plan. Further, I declare this plan to be the official natural hazards mitigation plan for Metro Nashville- Davidson County and its municipalities. It shall serve as the central policy and guidance document for such mitigation actions, upon all agencies and political subdivisions within. This plan is effective upon receipt and for execution when so directed. The Mayor's Office of Emergency Management (OEM) is responsible for maintaining and updating this plan, as required, in coordination with the appropriate departments, agencies and the community at large. Signed, ___________________________________________ Karl Dean, Mayor Metropolitan Government of Nashville and Davidson County Figure A-2 Mayor’s Promulgation Statement Metropolitan Nashville – Davidson County Appendix A Multi-Hazard Mitigation Plan Page A-6 April 2010
