Get Prepared for Storm Season

With fall upon us and rainy season approaching, it's a good time to take stock of your preparedness for flooding.

City staff members have been preparing Sunnyvale's stormwater system and ensuring that the city's two storm pump stations are ready.

Here’s what you can do to have a safe winter and protect yourself and your property.


Prepare for the Next Storm

  • Store emergency items such as first aid kits, flashlights and portable radios in a safe, high place.
  • Store drinking water in closed, clean containers in case water service is interrupted. Allow one gallon of water per person per day for at least three days; remember to include extra water for pets.
  • Consider installing a back-flow prevention device if any of your inside drains or fixtures are lower than the side sewer vent on the sidewalk.
  • Prepare written instructions on how to turn off electricity, gas and water if authorities advise you to do so. (Remember, you'll need a professional to turn them back on.)
  • Purchase flood insurance
  • Pick up free sandbags

During the Storm

  • If water has entered a garage or basement, do not walk through it.
  • If you are asked to leave your property, turn off utilities at the main switches or valves.
  • Disconnect electrical appliances. Do not touch electrical equipment if you are wet or standing in water.
  • Tune to local radio stations for emergency information and traffic updates.
  • Do not drive into flooded areas
  • Avoid downed power lines and broken gas lines.

After a Storm 

DO NOT TURN GAS BACK ON YOURSELF. Call PG&E 800-743-5000. 

  • Avoid direct contact with floodwater. Wear protective clothing, including heavy gloves, to remove wet materials that may be contaminated.
  • Follow local instructions regarding the safety of drinking water.
  • Do not use fresh foods or canned goods that have come in contact with floodwaters.
  • To prevent mold, flooded buildings should be pumped out, disinfected and dried as quickly as possible.
  • Do not handle live electrical equipment in wet areas and have them checked before use.
