“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) expired in 2019. NHMPs must be updated every five years.

Umatilla County is collaborating with the Oregon Department of Land Conservation and Development (DLCD) to update the NHMP. The updated NHMP will be 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.

This project is 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.
