Natural Hazards Mitigation Plan

Clackamas County is currently in the process of updating its Natural Hazards Mitigation Plan (NHMP), which will help the county plan for actions that can lessen the impact of disasters. The plan allows the county to identify risks associated with natural disasters, and work on long-term strategies for protecting people and property. In addition to being a proactive step in reducing risks, having a plan is a condition for receiving certain types of funding from FEMA, the Federal Emergency Management Agency. The funding can help with a variety of projects to mitigate risks, for example retrofitting roads, bridges, culverts and other structures to prevent recurring damage from winter storms or flooding.

The 2018 plan update includes the following changes:

  • Updating new information for completed risk reduction projects, plans, and improved characterizations of emerging hazards, such as drought, extreme heat, and other climate change-related impacts.
  • Improve the risk assessment section through an enhanced assessment of lifeline infrastructure systems.
  • Better integrate NHMP information in related county plans and planning documents.
  • The County is also forging partnerships with several local watershed councils to promote collaborations between floodplain management, stream, improved natural stream function, and habitat restoration.
