Power outages - prepare and navigate

During winter storms, heavy rain and strong wind gusts can cause power outages. To prepare for potential power outages, please follow these helpful tips from PG&E:

  • Make sure PG&E can reach you to alert you of a possible power outage by calling1-800-743-5000 and updating your contact information.
  • Pack an emergency supply kit with nonperishable food, one gallon of water per person per day, medications, flashlights, and batteries.
  • Fully charge your mobile phone and consider adding a battery-powered portabe charger to your emergency kit to extend the battery life of your phone.
  • Practice opening and closing your garage door manually.
  • If you have a car, be sure to fill the tank as gas stations may be closed during an emergency or power outage. If you own an electric vehicle, make sure you have enough charge to make it to a charging station outside of your immediate area.
  • Keep bills and cash on hand (preferably in small bills) in case ATMs are unavailable.

If your power goes out, call PG&E at 1-800-743-5000 and check their outage center map online.

PG&E offers additional tips on how to protect yourself during a power outage and after a power outage.

If you are interested in assisting Menlo Park neighbors during power outages and disasters, please consider joining the Community Emergency Response Team (CERT) of Menlo Park. CERT is a critical Menlo Park community program run by the Menlo Park Fire Protection District. The program currently has 60 volunteers and is seeking additional members. The Menlo Park Fire Protection District continually runs free training sessions to become a member of CERT as well as related trainings such as disaster preparedness. Learn more about CERT and register for upcoming classes.

Flood safety measures

  • Pay attention to evacuation orders. Listen to local radio or TV stations for forecasts and emergency warnings. Know about evacuation routes and nearby shelters and have plans for all family members on evacuation procedures and where to meet if you are separated during an emergency.

  • Do not drive through flooded areas. During a flood, more people drown in their cars than anywhere else. Do not drive around road barriers, the road or bridge may be washed out.  

  • Do not walk through flowing water. Flash flooding is the leading cause of weather-related deaths in the U.S. Water currents can be deceptive; six inches of moving water can knock you off your feet in a strong current. If you walk through standing water, use a stick or pole to help you locate the ground.

  • Stay away from power lines and electrical wires. Electrical currents can travel through water. Report downed power lines to 9-1-1 immediately, then call PG&E at 1-800-743-5000.  

  • Have the power company turn off your electricity. Some appliances, like televisions, keep electrical charges even after they are unplugged. Do not use appliances or motors that have gotten wet unless they have been taken apart, cleaned and dried.  

  • Look before you step. After a flood, the ground and floors may be covered with debris like broken bottles or nails. Floors and stairs that are covered with mud can be slippery  

  • Be alert for gas leaks. Use a flashlight to inspect damage. Do not smoke or use candles, lanterns, or open flames unless you know the gas has been shut off and the area has been ventilated.

Property protection measures

There are several ways you can protect your property from flood damage before the flood occurs.
If there is an imminent flood threat, you can take these emergency measures:

  • Place sandbags or plastic sheeting in front of doorways and other low entry points
  • Elevate furniture above flood protection levels
  • Move valuables to a higher level
  • Create floodway openings in non-habitable areas such as garage doors
  • Seal off sewer lines to the dwelling to prevent backflow of sewer waters

You can also make permanent changes to protect a building from flood damage:

  • Keep water away by regrading the lot
  • Build a small floodwall or earthen berm. This can be helpful for some houses on slab foundations.
  • If your house is on a crawlspace, a low floodwall, berm or “wet flood proofing” may help. Wet flood proofing means moving all items subject to flood damage out of harm’s way so water can flow into the crawlspace without causing problems.
  • Make the walls waterproof and put watertight closures over doors. This is called “dry flood proofing.”
  • If floodwaters go over the first floor, you can raise the building above flood protection levels.
  • Electrical panel boxes, furnaces, water heaters, washers and dryers should be elevated or relocated to a location less likely to be flooded.

Tips for safe driving in storms

  • Stay informed: Check local weather updates and road conditions before getting on the road. Subscribe to the San Mateo County emergency and non-emergency alerts.
  • Inspect your vehicle before leaving: check your tires, headlights and windshield wipers before leaving.
  • Turn your headlights on during rain: If your wipers are on, then your headlights should be on. Headlights must be turned on during darkness and inclement weather, which includes: rain, fog, mist and snow.
  • Reduce your speed: Slow down to allow time to react to unforeseen situations. Leave early to give yourself more time to get to your destination.
  • Increase vehicle distance: Increasing the distance between your vehicle and the one in front of you will allow you more time to react to any sudden change in conditions such as hydroplaning or sudden braking due to weather conditions.
  • Pull over for emergency vehicles: If an emergency vehicle with its lights or sirens on is headed your way, you must get out of the way as soon as possible.
  • Traffic Lights: Power outages due to weather may mean some traffic lights are out of order. If a traffic light is not functioning, it must be treated as a stop sign. Four-stop refresher: the first vehicle to arrive has the right of way and if multiple vehicles arrive at the same time then the vehicle to the right goes first.
  • Turn around, don’t drown: Do not attempt to drive through flood waters, it is safer to turn around and find alternate routes. Call 9-1-1 if you are trapped by moving water.
  • Be prepared: Keep a bag of emergency essentials in your vehicle, including: a flashlight, water, first aid kit, and blanket. For more emergency preparedness information please visit menlopark.gov/emergency-preparedness.

Please do not call 9-1-1 unless there is an imminent threat to life or other serious emergency. Let’s weather this storm out safely and responsibly.
