Clallam Hazard Mitigation Plan (HMP)

The HMP should more explicitly address climate
hazards and mitigation

The “big one” is expected to strike sometime within the next 2 centuries…but climate change has already struck and will worsen over the next several decades, causing disasters on the same order.

OCA members collaborated to review the County’s draft Hazard Mitigation Plan Update, noting the intensifying effect that climate change will have on the majority of disasters, as well as the common steps needed to mitigate all such disasters. We believe the HMP should more explicitly recognize climate threats and mitigation measures.

Hazard Mitigation Plan (HMP) Summary

The Clallam County HMP assesses the potential impact of all prioritized hazards to community members and property and provides mitigation strategies and actions to reduce such risks. The HMP prioritizes these strategies and includes an implementation plan to ensure strategic actions are carried out. The 2019 HMP is the required update of the County’s 2010 HMP, expanded to account for both natural and human-caused hazards. The updated HMP ensures community members have access to the most up-to-date hazard risk information and maintains the County and participating communities’ eligibility to receive federal mitigation funding.

Hazard ranking methodology

HMP planning committee participants were asked to rank hazards based on five key attributes:

  • Probability: Likelihood of the hazard occurring.
  • Magnitude: Areas potentially impacted, the overall impacts, and the chance of one hazard triggering another hazard, thus causing a cascading effect.
  • Onset: The time between recognition of an approaching hazard and when the hazard begins to affect the community.
  • Duration: The length of time the hazard remains active, the length of time emergency operations continue after the hazard event, and the length of time that recovery will take.
  • Frequency: How often a hazard has resulted in an emergency or disaster.
