What is Hazard Mitigation?

According to the Federal Emergency Management Agency (FEMA), hazard mitigation is:

 “the effort to reduce loss of life and property by lessening the impact of disasters. It is most effective when implemented under a comprehensive, long-term mitigation plan. State, tribal, and local governments engage in hazard mitigation planning to identify risks and vulnerabilities associated with natural disasters, and develop long-term strategies for protecting people and property from future hazard events.”

History of the DuPage County Natural Hazard Mitigation Plan (NHMP)

The DuPage County NHMP was first developed in 2007, through a grant awarded to DuPage County Stormwater Management. In 2010, the DuPage County Office of Homeland Security and Emergency Management (OHSEM) became the official governing body of the plan and the associated workgroup. Personnel from the OHSEM coordinated the 2012 plan update and 2013 plan adoption. Following the County’s adoption in May 2013, DuPage County municipalities adopted the plan.  

    2017 Plan Update

    On November 6th, 2017 the DuPage County’s Office of Homeland Security and Emergency Management, Stormwater Management, Building and Zoning Department, and the Department of Public Works, held a kick-off meeting to begin the 5 year update to the NHMP. Municipal representatives from Emergency Management, Stormwater, and Public Works were invited from all municipalities, cities, towns, and villages within and touching the County borders. Prior to the meeting, the County distributed a survey to each municipality requesting feedback on both the 2013 plan and the update.

    The County worked to form a collaborative County and municipal workgroup to assist with the plan update, and coordinated a public outreach meeting and survey. The workgroup met to assess the County’s hazards, problems associated with each hazard, develop goals for the County as a whole, and developed mitigation strategies. The workgroup worked to ensure these strategies encompassed the following seven categories of mitigation:

    • Preventative Measures
    • Property Protection
    • Natural Resource Protection
    • Emergency Services
    • Structural Flood Control Projects
    • Public Information

    The plan was reviewed by the Illinois Emergency Management Agency (IEMA) and FEMA. Following the plans approval, the County Board and participating municipal boards adopted the plan through a formal resolution.
