What is mitigation?

Mitigation is the effort we take to reduce loss of life and property by lessening the impact of disasters. By taking action now - before the next disaster - to reduce the human and financial consequences later. Examples of mitigation actions include restoring flood plains to prevent flooding in urban areas, securing bookshelves and appliances to reduce hazards, or replacing aging public infrastructure to be more disaster resilient.

Why do we need a Natural Hazard Mitigation Plan?

Mitigation planning creates safer communities, saves money, and enables individuals to recover more rapidly from disasters. With a federally approved plan in place, Multnomah County and the jurisdictions covered by the plan are also eligible to apply for grant funding for hazard mitigation projects. These funds can assist with mitigation actions identified during the hazard mitigation planning process.

The county's role in updating the plan

Multnomah County adopted its first hazard mitigation plan in 2006.  Since then, the county updates the plan every five years to reflect changes in development, progress in local mitigation efforts, and changes in priorities. We are currently in the process of a major update that includes the Cities of Fairview, Gresham, Maywood Park, Troutdale, and Wood Village.
