Natural Hazards Mitigation Plan

Clackamas County's  2019 Multi-jurisdictional Natural Hazards Mitigation Plan helps 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.

  • 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.
