Plainly stated, hazard mitigation is any action taken to reduce or eliminate the long-term risk to human life and property from natural hazards.

The mission of the Illinois Mitigation Program is to identify hazards that affect Illinois, assess how vulnerable Illinois is to each hazard, and then implement a strategy for mitigating the effects of the hazard.

The program is intended to:

  • ​Provide the framework for hazard mitigation not only during the recovery and reconstruction process, but also on a year-round basis.
  • Identify mitigation projects that will reduce the potential for future losses and decrease the cost to taxpayers.
  • Provide education to the public on mitigation methods and offer assistance to local jurisdictions that are eligible for mitigation projects.
  • Assist all Illinois jurisdictions in completing a Disaster Mitigation Act of 2000 compliant plan.

This mitigation section is not only an introduction to hazard mitigation in Illinois, but also a planning tool for those communities that wish to implement a program in their jurisdiction.​
