Wisconsin is vulnerable to a variety of disasters. The state has incurred disaster-related damages totaling nearly $3 billion in the last three decades, with almost half of that occurring in the '90's alone. These losses can be reduced through mitigation activities. It is estimated that for every dollar spent on mitigation, $2 to $3 in future damages can be avoided. Hazard mitigation breaks the cycle of damage and repair. Mitigation actions reduce or eliminate the long-term risk to human life and property from hazards. These preventative actions can be simple such as elevating a furnace in a basement that sometimes has water on the floor. Mitigation can also have a comprehensive approach such as relocating buildings out of the floodplain or strengthening critical facilities to prevent wind damage and provide stronger shelter.

Since November 1, 2004, communities and Indian tribal governments are required to have an approved all hazards mitigation plan to be eligible for Hazard Mitigation Grant Program (HMGP) grant funds.
