This essential step includes identifying and organizing interested members of the community as well as the technical expertise required during the planning process.  There are multiple levels of participation:

  • Steering Committee - advisory committee representing community planning, emergency management, and public works interests from each jurisdiction
  • Interested Stakeholders - representatives of local governments, agencies, non-governmental organizations, and others potentially affected by the planning outcomes
  • Subject matter experts for identified hazards
  • Community members

Hazard Identification and Risk Assessment

A hazard analysis determines what types of hazards are present within Multnomah County and the associated risk.  The current plan identifies the following hazards:

During the plan update the Steering Committee is reassessing the hazard identification and update risk assessments.  In addition, grant funding was received to address technological and human-caused hazards.

Public engagement

Early in the update process, the Multnomah County Office of Emergency Management worked with individual cities and communities to provide engagement opportunities during the summer of 2015.

Developing a mitigation strategy

One of the benefits of the planning process is identifying strategies and actions that can be taken to mitigate against the hazards identified in the plan. The following are some examples of mitigation actions and strategies. Items with links are actions taken by the County and local jurisdictions as examples of mitigation actions.

Mitigation actions take into account life safety, property protection, technical feasibility, public support, environmental impacts, and other community objectives.

Completing the draft plan

The input received during the planning process will be integrated into a 2017 draft plan for review by stakeholders and the public. The 2017 update also includes a merging of the county and cities of Gresham, Troutdale, Fairview, and Wood Village plans into one multi-jurisdictional plan. The City of Portland  

Hazard mitigation plan approval process
currently maintains a separate hazard mitigation plan.  

Plan approval and adoption

When the updated plan draft is complete, and stakeholder and public engagement input has been received, the plan will go to the State of Oregon for preliminary approval. Once that approval is received, the plan is forwarded to FEMA for final approval. The approved plan is then brought to respective City and County Commissioners for local approval and adoption.
