County Plans and HSEM Plan


Tornado Frequency

The Multi-Hazard Mitigation Plan (MHMP) is a requirement of the Federal Disaster Mitigation Act of 2000 (DMA 2000). The development of a local government plan is required in order to maintain eligibility for certain federal disaster assistance and hazard mitigation funding programs. In order for the National Flood Insurance Program (NFIP) communities to be eligible for future mitigation funds, they must adopt an MHMP. The Hazard Mitigation Plan evaluates and ranks the major natural, technological and domestic preparedness hazards, affecting a county as determined by frequency of event, economic impact, deaths, and injuries. Mitigation recommendations are based on input from state and local agencies and national best practices.

 

 

 

 

We have direct experience with both county and state-level Hazard Mitigation Plan updates, working with Lake County (2011), Brown County (2012), Le Sueur County (2013), in addition to the State of Minnesota and the Division of Homeland Security and Emergency Management (2014). These efforts have included conducting appropriate research to develop text and maps that will clearly describe and update the counties' community profile, land use, disaster history, hazard analysis and risk assessment. We were required to design and implement strategies for input by county departments, other partners and the public on risk assessment and mitigation strategies. We facilitate public meetings to develop and gather input on hazard mitigation strategies and priorities using the STAPLEE Benefit-Cost Review process.

 

 

 

The University of Minnesota Duluth Geospatial Analysis Center (GAC) is assisting counties with performing the hazard risk assessment for 100-year floods using the Hazus-MH GIS tool. This tool enables communities of all sizes to predict estimated losses from floods, hurricanes, earthquakes, and other related phenomena and to measure the impact of various mitigation practices that might help reduce those losses. The Minnesota Homeland Security and Emergency Management office has determined that Hazus-MH should play a critical role in Minnesota's risk assessments, and therefore the 100-year flood event hazard analysis was introduced in the 2010 plans.
