National Preparedness Month


Launched in 2004 by the Federal Emergency Management Agency (FEMA), this national observance is designed to educate, encourage and help individuals prepare to respond to all types of emergencies and natural disasters. Preparation involves three key steps:

Staying Informed

National or widespread emergencies. During and immediately after a national or widespread emergency or imminent threat such as a terrorist attack, natural disaster, or AMBER alert, federal, state and county government officials will use the Wireless Emergency Alerts (WEA) system to automatically push messages to all cell phones and mobile devices within the affected geographical area. 

Localized emergencies. For localized emergencies or public safety threats affecting all, or a significant portion, of Diamond Bar, the City will use its Emergency Alert System known as Civic Ready. Examples of emergencies that will trigger an alert are wildfires, severe flooding, and significant hazardous material spills. Everyone who lives, works, or has family members living in town is encouraged to register their cell phones, email addresses, home, or work phones by visiting

Making a Plan

Every household should have an up-to-date emergency plan that every member of the family is aware of and ready to put into action as soon as a disaster or emergency occurs. The plan should be practiced regularly with modifications made as need to include any new family members, school or work changes, reunion locations, and out-of-state contacts. A helpful step-by-step guide on how to create a Family Emergency Communication Plan is available at

Building a Supply Kit

At minimum, every emergency supply kit should contain one gallon of water per person per day for several days, a three-day supply of non-perishable food, a battery-powered or hand crank radio, flashlights, first aid kit, batteries, wrench or pliers to turn off utilities, a manual can opener for canned goods, and any special food, supplies or prescriptions needed for newborns, seniors, or pets. The items should be stored in one or two plastic bins or duffle bags with wheels and kept in a cool, dry place. The kit should be reviewed and updated once a year to add or replace items as needed. An emergency supply checklist is available

Scheduled Test of the City’s Emergency Alert System

At 10 a.m. on Thursday, September 30, the City will be testing its emergency alert system to ensure it is operating properly. The test message will be sent by text, email and/or call depending on the preferences each registrant selected at sign-up. To make changes such adding or deleting a phone, visit
