There is a very great distinction because when you are planning for an emergency you must start with this one thing: The very definition of "emergency" is that it is unexpected, therefore it is not going to happen the way you are planning.” -Dwight D. Eisenhower HAZARD MITIGATION PLAN DEFINITIONS ”A natural hazard is a source of harm or difficulty created by a meteorological, environmental, or geological event.” “Hazard mitigation is any sustained action taken to reduce or eliminate the long-term risk to human life and property from hazards (44CFR 201.2). Hazard mitigation activities may be implemented prior to, during, or after an event. However, it has been demonstrated that hazard mitigation is most effective when based on an inclusive, comprehensive, long-term plan that is developed before a disaster occurs.” (Source: Local Mitigation Plan Review Guide, FEMA, October 1, 2011) Plan Prepared and Authored By June E.
