The Hamilton County Multi-Hazard Mitigation Plan (MHMP or Plan) was developed to guide the County in a risk-based approach to become more resilient to the impacts of natural and technological hazards through mitigation planning. The Plan documents historical disasters, assesses probabilistic disasters through Hazus-MH and GIS analyses, and addresses specific strategies to mitigate the potential impacts of these disasters.

This five-year update was a collaborative effort among the Hamilton County planning team and Integrated Solutions Consulting.

The Hamilton County MHMP:

  • Identifies areas of risk and assesses the potential cost and magnitude
  • Establishes strategies and priorities to mitigate risk from natural and technological hazards
  • Identifies specific mitigation projects to pursue for each identified hazard
  • Guides the communities in their risk management activities and minimizes conflicts among agencies
  • Establishes eligibility for future mitigation program funds

The 2018 MHMP includes the following key updates:

  • Historical hazards: Each hazard section within this plan documents NCDC-reported hazards within the past five years. Where data are available, historical hazards are graphed by decade, showing disaster trends over the past 50 years.
  • County profile: Demographics, social, and economic data, as well as existing and future land use descriptions, are updated to reflect the current status of the county and its jurisdictions.
  • Planning description: The new planning team and updated planning process are described and documented.
  • Risk assessment: The updated risk assessment includes Hazus-MH and GIS analyses that utilize site-specific data from the county. Hazards were identified and expanded to better integrate with the County’s THIRA. Each participating jurisdiction provided their own hazard analysis, which describes the hazards and their impacts as they pertain specifically to the community.
  • Mitigation: The mitigation section addresses status of previous plan’s strategies in addition to new mitigation goals, objectives, and strategies.
