Flood Information and Winter Storm Preparedness
Flooding is a potential risk, primarily from the San Francisquito Creek which runs along the City's Northern border, but also from the San Francisco Bay as well as Matadero, Adobe, and Barron Creeks between November and March each year. The neighboring jurisdictions of the San Francisquito Creek are working to mitigate the flood risk to our communities, but where there is still a risk we should be prepared for it. This page provides a number of steps and resources to help you prepare for a flood incident.
What You Can Do To Prepare
Regardless of the seasonal forecast for winter weather, it pays to be prepared. The City of Palo Alto suggests a few things you can do to be ready for the very real possibility of flooding in our area.
Before the Storm
- Sign up for automated notifications from the City of Palo Alto, visit alertscc.com.
- Visit and explore our Emergency Preparedness webpage.
- Know if your property is in a flood zone. Lookup your address at the FEMA Floodmap Service Center.
- Regular homeowner's insurance policies don't cover flood damage. Call your insurance agent to purchase flood insurance to protect your home and contents. Find more information at www.Floodsmart.gov
- Discuss emergency plans with your family. The Red Cross Flood Safety website provides more details of this and other topics.
- Know where and how you will evacuate if necessary.
- Plan in advance to assist your neighbors or have them help you. Plan for those with access and functional needs, mobility problems or other disabilities.
- Register to receive Flood Warnings for the San Francisquito Creek from the San Francisquito Creek Joint Powers Authority.

- Store the following emergency supplies at work, home and in your car.
- First Aid kit and essential medicines
- Food (packaged, dried, canned or for special diets)
- Cash (ATMs may not work)
- Portable radio, flashlights and extra batteries (stored in watertight plastic bags).

During the Storm
During a time of emergency, the City's primary duty is to ensure public safety. In the case of a flood, City resources are directed toward evacuating residents as necessary, responding to police, fire, and medical emergencies, maintaining utility services, providing traffic control, and pumping water to reduce flooding.
