Prepare yourself, your family, and your home or business for potential disaster or emergency is everyone's responsibility. In the event of a major disaster, you can be sure that Half Moon Bay, San Mateo County, and other emergency services staff will be doing all they can to ensure the public safety, restore services, and return our community to normal. 

But remember, disaster can strike quickly and without warning. It can force you to evacuate your neighborhood or "shelter in place" in your home. You and your family may be without basic services like water, gas, electricity, and telephones, or access to stores and other services for several hours or days. While public safety personnel will be on the scene after a disaster, they cannot reach everyone right away.

Therefore, the best way to make your family and your home safe is to be prepared before disaster strikes. Half Moon Bay urges everyone to be responsible for their own and their family's safety and emergency preparedness by taking the time now to plan for such a situation.

What You Can Do To Prepare For Disaster

1. Register for SMCAlert
SMCAlert will help you stay informed with immediate information by signing up to receive emergency alerts via text, phone, or email from the San Mateo County Office of Emergency Services.

2. Prepare an emergency/evacuation plan and discuss with your family
Learn the safest route to high, safe ground if you have to evacuate in a hurry. Decide on a place where your family can meet during and after a disaster strikes.

3. Prepare emergency supplies
Experts say that families need to be prepared to be self-reliant (that is, able to get along without any outside services or assistance) for 72 hours. Ideally prepare for full seven days. 

4. Know how to disable utilities
Learn how to shut off your gas here. If you smell natural gas, see downed power lines, or suspect another power-related emergency situation, call 9-1-1 and then call PG&E at 800.743.5000. Never touch a downed power line. Do not touch any electrical equipment

What To Do During And After A Disaster

Evacuation Be ready to evacuate if directed by emergency personnel - the City/County may order optional or mandatory evacuations depending upon conditions. If evacuations are called for, it is imperative that you follow instructions of emergency personnel in the time frame noted.

See the evacuation planning tools and information.

Provide safe drinking water
Ensure your household has a safe source of drinking water. In the event of major flooding or other major disaster, you may want to fill bathtubs, sinks, and jugs with clean water in case regular supplies are shut off or contaminated.

In the Event of Flooding

The west coast is subject to earthquakes, including deep sea earthquakes that could cause a tidal wave, or tsunami. While less likely than most other types of disasters, it’s a good idea to keep tsunami in mind when assessing your home’s disaster preparedness. Here are some tsunami information resources:

Overview of Coastside Preparedness and Response Groups
What do all those Coastside acronyms mean, anyway?

CEC - Coastside Emergency Corps: In the event of an emergency or disaster, CEC volunteer members may be activated to respond to an incident scene, a Red Cross shelter, or the Emergency Operations Center to assist. To join CEC, applicants must have documented qualifying skills, which may include CERT, ham radio, Large Animal Evacuation Group, Red Cross shelter operations, medical (beyond first aid/CPR) or ICS/EOC training. For more information, visit

CEAP - Coastside Emergency Action Program: CEAP is an organization that meets once a month, bringing together representatives from business, public safety, health care, and community support groups to discuss ways to integrate these different interests to work together to better help the Coastside during disasters. CEAP members are not activated to assist first responders unless they also belong to the CEC, which many do. The CEAP website is

CERT - Community Emergency Response Team: CERT is a FEMA program designed to help citizens prepare for disaster, through training courses in the FEMA curriculum. CERT graduates are free to help neighbors prepare, but they are not automatically part of the CEC and therefore will typically not be activated to assist first responders during emergencies or participate in exercises. Visit the San Mateo County Office of Emergency Services web page for more information about CERT classes.

CEPC - Coastside Emergency Prep Club: This is a group of neighbors working "grassroots" on a variety of emergency prep projects. You don't have to be CERT or CEC, or have any special skills or training. You only have to be interested in getting prepared, and/or helping others to prepare, as well. You will not be activated to assist first responders during emergencies or participate in exercises, but you will be better prepared to take care of yourself, your family and your neighbors. Any Coastside resident can be part of the CEPC - it's organized and managed by Coastside resident Michelle Dragony, who can be reached at This e-mail address is being protected from spambots.
