About NHMP Updates
The Multnomah County Multi-Jurisdictional Natural Hazards Mitigation Plan (NHMP) is being updated. A draft of the plan is now available to review, and your comments are important. Feedback that is provided will be used to improve the final plan, and be maintained to continue to guide future updates.
The plan provides a comprehensive view of the risks to Multnomah County from earthquake, flood, landslide, severe weather, volcano, and wildfire and wildfire smoke – and strategies for lessening the impact of those future disasters. The plan update has been in process since 2021 and includes the Cities of Fairview, Gresham, Troutdale and Wood Village; Multnomah County; the Columbia Corridor Drainage Districts (Peninsula 1, Peninsula 2, Multnomah County Drainage District, and Sandy Drainage Improvement Company plus two future consolidated districts); and the Port of Portland. The City of Portland has their own Mitigation Action Plan, which was recently updated.
Comments received by February 10 will be considered for final updates to the plan, and all comments will be maintained to help guide future hazard mitigation planning. Note that this version is a draft, so there will be continuing edits and format changes before the final version of the plan is released. The mitigation actions for each participating entity are located at the beginning of their respective jurisdictional chapter. The mitigation actions are the most important part of the plan for receiving comment, as they indicate the priorities of each participating entity over the next five years.
