“to prevent loss and protect life, property and the environment from the risk of natural hazards through coordination and cooperation among public and private partners”

About the Plan

Umatilla County’s existing Natural Hazards Mitigation Plan (NHMP) was approved by FEMA in August 2021. NHMPs must be updated every five years.

The updated 2021 NHMP is a multi-jurisdictional document that includes the county’s 12 incorporated cities and several special districts. The updated NHMP will ensure the  county, cities, and special districts maintain eligibility for federal disaster-related funding.

The participating jurisdictions and special districts are required to have bi-annual maintenance meetings. NHMP Maintenance meeting Agendas and Notes

This project was made possible by the federal Hazard Mitigation Grant Program (HMGP). The HMGP assists states, tribes, and local communities in implementing long-term hazard mitigation measures following a major disaster declaration to reduce the risk of loss of life and property from future disasters.
