All-Hazards Mitigation Plan (AHMP)

The Clermont County Emergency Management Agency would like to thank all of our Cities, Townships, Villages, and County government agencies, public safety stakeholders, community partners,  Ohio Emergency Management Agency, and the general public for their participation and feedback on the All-Hazards Mitigation Plan.    The updated plan was adopted by the Board of County Commissioners on April 22, 2020.  We received the official approval from FEMA on June 15, 2020.   The updated plan is valid until June 14, 2025.


What is hazard mitigation?

Hazard mitigation is any cost-effective and sustained action taken to reduce or eliminate the long-term risk to human life or property from natural, technological, and human-caused hazards.

What is the purpose of hazard mitigation planning?
The purpose of All-Hazard Mitigation Planning is to:
  • Identify the hazards that impact Clermont County, including the Cities, Villages, and Townships within the County;
  • Identify actions and activities to reduce any losses from those hazards; and
  • Establish a coordinated process to implement the Plan.
What is the benefit of hazard mitigation planning?
The benefits include:
  • Assisting local communities with reducing risks by identifying vulnerabilities and developing strategies to lessen and/or eliminate the effects of a potential hazard;
  • Building partnerships and reducing duplication of efforts among organizations with similar or overlapping goals;
  • Creating more sustainable and disaster-resistant communities;
  • Communicating needs to state and federal officials when funding becomes available, particularly after a disaster; and
  • Increasing public awareness of local hazards and disaster preparedness.
What laws govern the hazard mitigation planning process?
State, Indian Tribal, and local governments are required by 44 CFR Part 201 to develop a hazard mitigation plan as a condition for receiving certain types of non-emergency disaster assistance, including funding for mitigation projects. The Robert T. Stafford Disaster Relief and Emergency Assistance Act (Public Law 93-288), as amended by the Disaster Mitigation Act of 2000, provides the legal basis for State, local, and Indian Tribal governments to undertake a risk-based approach to reducing risks from natural hazards through mitigation planning.
