Hazard Mitigation Planning


The Macomb County Hazard Mitigation Plan identifies natural and human-caused hazards that pose a threat to the community; it ranks the hazards based on the potential threat they pose to the population, property, and the economy; and it recommends projects to reduce or eliminate the potential impacts of the identified hazards.

Each community in the county, as well as the county itself, adopts the plan as the official hazard mitigation plan for the jurisdiction.

The plan was last revised in 2014, and was approved by the Michigan State Police Emergency Management and Homeland Security (MSP EMHSD) and the Federal Emergency Management Agency to cover the timeframe of 2015-2020.

The current plan identifies the following 27 hazards:

  • Civil Disturbance
  • Dam Failure
  • Drought
  • Earthquake
  • Energy Emergency
  • Extreme Temperature
  • Hail Storm
  • Hazmat – Fixed Site
  • Hazmat – Transportation
  • Ice & Sleet Storms
  • Infrastructure Failures
  • Lightning
  • Nuclear Attack
  • Nuclear Power Plant Accident
  • Oil & Gas Well Accident
  • Pipeline Accident
  • Public Health Emergency
  • Riverine Flooding
  • Severe Wind
  • Shoreline Flooding
  • Snowstorm
  • Structural Fires

  • Terrorism/WMD/Sabotage

2020-2025 Update

Beginning in September 2018, Macomb County Emergency Management along with the communities located within the county will be updating the plan to cover the period of 2020-2025.

There are several areas within the plan where the public can provide valuable feedback, and we encourage Macomb County residents and business owners to get involved. From now until November 4th, members of the public can provide their perspective on the hazards that most impact their community by completing a Hazard Risk and Vulnerability Assessment. All responses will be factored into the county’s final hazard ranking.
