Chapter 6. Finding and Recording Your Evacuation Zone
An evacuation zone is a defined geographic area that public-safety agencies may use to communicate evacuation warnings, evacuation orders, shelter-in-place instructions, and changes in emergency status. Knowing your zone before a wildfire, hazardous-material incident, flood, or other emergency can help you understand whether an official instruction applies to your location.
Residents of Pleasanton, Dublin, Livermore, San Ramon, Danville, Sunol, and nearby communities should determine whether their jurisdiction provides an official evacuation-zone map. Because systems and boundaries may differ among cities and counties, never assume that a zone used in one part of the Tri-Valley applies everywhere.
Evacuation-zone information may also change. A zone identifier written down several years ago should be checked against the current official system.
Begin with an Official Local Source
Start with the emergency-preparedness website operated by your city, county, fire department, sheriff’s office, or office of emergency services. Look for a section labeled “Know Your Zone,” “Evacuation Zones,” “Emergency Map,” or “Evacuation Information.”
Follow the link provided by that agency rather than relying on an unofficial search result, community post, old flyer, or forwarded message. An official-looking map copied into a neighborhood group could be outdated or incomplete.
Pleasanton currently directs residents to Genasys Protect to check their evacuation zones and view zone statuses. The city explains that fire and law-enforcement agencies can issue evacuation warnings or orders for affected zones. Residents can reach the current evacuation resource through the City of Pleasanton emergency-preparedness page.
The Alameda County Fire Department emergency-preparedness page also directs residents to Genasys Protect to identify their zones and prepare for evacuation. People in other jurisdictions should confirm the system currently designated by their own city and county.
If your local agency does not publish an evacuation-zone system, do not create or adopt an unofficial zone designation. Register for the jurisdiction’s emergency alerts, save its official emergency-information page, and follow address-based or area-based instructions issued during an incident.
How to Look Up Your Zone
When directed to an official evacuation map, enter the complete street address for the location you want to identify. The map may display a boundary and an alphanumeric zone designation. Write down the identifier exactly as shown, including letters, numbers, hyphens, or other characters.
Do not identify a zone merely by looking at the general position of a neighborhood on the map. A street, subdivision, apartment complex, or rural property may be close to a boundary. Enter the specific address and zoom in sufficiently to confirm where it falls.
Record zones for all important locations, including:
- Your home
- Your workplace or business
- Children’s schools or childcare facilities
- An older relative’s home
- A family member with disabilities or medical needs
- A pet boarding facility
- A stable or property where livestock are kept
- A second home or frequently visited location
A household may need to monitor more than one zone. Family members could be separated when an evacuation warning is issued, and each person’s location may have a different status.
Record the Information in More Than One Place
Write the zone identifier on your household emergency plan and place a copy in each go-bag. Save it in every adult household member’s phone and include it with emergency contacts. You may also place a small reminder inside a kitchen cabinet or another accessible location.
A simple record might include:
Home address:
Official evacuation zone:
Jurisdiction:
Official map or website:
Date last verified:
The “date last verified” is important. It reminds residents that the information was accurate when recorded but is not guaranteed to remain unchanged.
Help older relatives, neighbors, and people who are less comfortable using online maps find and record their zones. Explain how to reach the official source themselves. Avoid publicly posting someone’s exact address, medical needs, telephone number, or evacuation plans in a neighborhood group.
A Zone Is Not an Evacuation Route
Knowing your evacuation zone does not mean that you know which road will be safe during every emergency. A zone identifies an area that authorities can reference when issuing instructions. It does not guarantee a particular evacuation route, shelter, destination, or departure time.
Fire, smoke, flooding, fallen trees, damaged power lines, traffic congestion, law-enforcement activity, and emergency vehicles can make a familiar road unsafe. A route that worked during a previous evacuation may be closed during the next incident.
Households can identify several possible ways out of their neighborhood as part of advance planning, but they must follow current directions from public-safety personnel during an actual evacuation. Never enter a closed road or restricted area because it appears usable on a personal navigation application.
Check the Zone’s Current Status
Recording a zone is only a preparedness step. During an emergency, residents must check the zone’s current status through the official system and read the complete notice.
Confirm:
- The issuing agency
- The affected zone or address
- Whether the notice is a warning, order, shelter-in-place instruction, or advisory
- The date and time of the latest update
- The required action
- Any official route, closure, shelter, or destination information
- Whether an earlier instruction has been changed or lifted
A saved screenshot shows only what the map displayed at one moment. It may not show later expansions, reductions, cancellations, or route changes. The City of Pleasanton advises residents to check their zones frequently during an incident because evacuation conditions can change quickly.
Knowing your evacuation zone can reduce uncertainty, but it does not replace registering for official alerts. Use the zone map together with local alert systems, government websites, authorized agency accounts, radio or television, and direct instructions from emergency personnel.
Helpful Hint
Write down your evacuation zone and help older relatives or neighbors locate theirs. Record the official source and the date checked—but verify the zone again whenever official maps or systems are updated.
Important Safety Reminder
Use this guide to prepare before an emergency. Zone boundaries, evacuation routes, and instructions must be confirmed through current authorized sources. Community groups can help neighbors safely, but they should never replace or contradict official instructions. Call 911 when someone faces an immediate threat to life, safety, or property.
Important Preparedness and Safety Notice
This chapter provides general preparedness education, not real-time emergency instructions. Conditions, evacuation zones, routes, shelters, road closures, and public-safety directions can change rapidly. During an emergency, consult current information from authorized public agencies and follow all instructions issued by emergency officials. Call 911 for an immediate threat to life, active fire, serious injury, crime in progress, or another urgent emergency.
