threat of natural, human induced and technological hazards through the assessment of these hazards and through the development of an action plan specifying goals, objectives, and strategies. Through this advanced planning, Crow Wing County will continue to be a leader in ensuring the safety and public protection of the entire countywide community. The purpose for the creation of this plan is to: 1. Foster communication between cities, townships, busiinesses, community organizations, public and private facilities, organizations, and similar entities throughout the county 2. Promote sound public policy designed to protect life and property from natural, human caused and technological hazards 3. Develop and implement educational programs to increase public awareness of the risks associated with all hazards 4. Provide for a safer and more enjoyable countywide community 1.2 Backkground The Crow Wing County All Hazard Mitigation Plan was funded through the Pre- Disaster Mitigation (PDM) Program established by the Disaster Mitigation Act of 2000 and through county in-kind contributions. Intended to break the cycle of disaster and rebuild. The Federal Emergency Management Agency (FEMA) program offers financial assistance to local governments to prepare and implement their local all hazard mitigation plans. More information on the PDM program can be found through the Federal Emergency Management Agency, Minnesota Homeland Security and Emergency Management, or the Minnesota Loocal Planning Assistance Center. 1.3 Introduction Definition of Mitigation: Hazard Mitigation is defined as any action taken to eliminate or lessen the risk of natural and human caused or technological hazards to life and property. Mitigation measures might include public education, development of regulations or public policy, structural hazard control or 09/01/2010 Page 7 Crow Wing County Hazard Mitigation Plan protection projects, altering or retro fitting facilities, acquisition or relocation of structures, or the development of improved or increased warning systems. 1.4 The Planning Process To assist in
