Hazard Mitigation Plan

What is the NHMP?

The Diamond Bar Natural Hazards Mitigation Plan (NHMP) establishes the City's strategy to put into practice improvements and programs to lessen community impacts in the event of natural hazardous events. A requirement of the Federal Disaster Mitigation Act of 2000 (DMA 2K), the NHMP comprehensively identifies potential hazards, the extent of the risks posed by hazards, the vulnerabilities of the city to those hazards and the action the City will take to mitigate or reduce the potential impact of the hazards.

NHMP Update Survey

The  City is currently in the process of updating its Natural Hazard Mitigation Plan. The plan aims to minimize, or eliminate the long-term risk to human life and property from known hazards, like droughts, floods, wildfires, and other major disasters.

As part of the update, the City is seeking input from the community to help identify, analyze, and prepare for potential hazards affecting Diamond Bar by taking a short survey. The survey also asks residents to share if they have been affected by a disaster and to help identify areas of the community they feel are particularly vulnerable in the event of a natural disaster. 


Let us know what you think about hazards and how they affect you and your family by taking a few minutes to complete the survey. Available until May 22, 2021
