Mission Statement

We work to protect our own, our family’s and our neighbors' lives, the environment, and property through emergency preparation, disaster response, emergency first aid and rescue actions, and public education.

Program Implementation

Our goal is to create a prepared and resilient community that will have an orderly and calm response to an emergency, disaster or prolonged utilities disruption. Additionally, we connect neighbors so that the community works cohesively and effectively together. Coastside CERT accomplishes these goals with a core leadership team supporting dual synergistic programs:

  1. Delivering free training for
    • Community Emergency Response Team (CERT)
    • Listos Program
  2. Coordinating Neighborhood Emergency Preparedness

Our training program ensures that, when officially activated, our CERTs will be the source of reliable, actionable information for first responders and be visible and useful resources for the neighborhoods.

Community Emergency Response Team (CERT) Program

CERT is a national program that trains the general public in basic disaster preparedness, such as fire safety, light search and rescue, team organization, and disaster medical operations. Here on the Coastside, Chief Cosgrave also covers hazards specific to our coastal community.

Coastside CERT provides free 24-hour basic emergency preparedness training program, advanced CERT courses, refresher courses, and special topic presentations. For information on upcoming classes see our Training page.

Listos Program

Listos ( is a state-wide grassroots disaster preparedness program that can be tailored to meet the individual needs of Spanish-speaking communities. Family-oriented and taught in Spanish, the program is delivered in a format that is both culturally and linguistically appropriate for the target population. Listos training dates on the Coastside will be announced later in the year.

Neighborhood Emergency Preparedness

Coastside CERT’s Neighborhood Emergency Preparedness is a local, homegrown grassroots program that relies on community involvement. Neighborhoods are meeting to define their own priorities and organize themselves around three objectives:

  1. Prepare each residence. This focuses on basic emergency preparation and hazard mitigation.
  2. Meet your neighbors before a disaster and create an emergency response plan for each block and neighborhood. This includes neighbors helping neighbors, rally points and a communication plan with first responders.
  3. Implement resilient shelter-in-place resources. This includes, but is not limited to, alternative power sources, water purification, telecom microgrids.

We encourage all levels of participation:

  1. Don’t have any spare time? Prepare yourself with:
    • Water — 1 gallon per day per person (don’t forget your pets!)
    • Food — items that don’t need to be refrigerated or cooked (don’t forget your pets!)
    • First aid kit — including prescription and over-the-counter medications
  2. Can check on your immediate neighbors? Coordinate with your Block Captain.
  3. Can help disseminate information to your block? Volunteer to be a Block Captain.
  4. Can facilitate meetings in your neighborhood and liaise with Coastside CERT and other neighborhoods? Volunteer to be a Neighborhood Lead.

We can’t do everything at once, but we can make progress towards resilience in small, coordinated steps, emphasizing common sense communications, cooperation, resource management, and risk mitigation.

As of March 1, 2020 our neighborhood overview is:

  • 32 neighborhoods
  • 1,218 in the database
  • 221 CERTs
  • 105 Hams
  • 123 Leads and 42 Support

For more details on each neighborhood, please see the Roster Summary spreadsheet and our Neighborhoods > Get Involved page.

Why is Emergency Preparedness Important?

While we are part of the larger Bay Area, we only have two, mostly two-lane roadways leading in and out, which greatly increases our chances of complete isolation in a regional disaster. We are subject to: earthquakes, tsunamis, fires, mudslides, road washouts, treefalls, bridge destabilization, tunnel closures, and utility and telecommunications disruptions.
