Flooding Can Happen in Milpitas

Flooding can happen anywhere in Milpitas during extreme rainfalls, but typically occurs after several days of heavy rain that saturates the ground. It can strike quickly with little to no warning. When facing any type of emergency, it is always better to be prepared. Read on to learn how you can prepare for flooding as well as what steps to take during and after flooding occurs.

  1. Prepare a family disaster plan and emergency kit for your home and car with supplies. Store important documents and valuables in a safe deposit box.
  2. Designate a family meeting spot.
  3. Know the flood warning and procedures and plan escape routes to high ground.
  4. Examine your house for cracks in the foundation, exterior walls and small openings around pipes. Seal them.
  5. Gather building materials like plywood, plastic sheeting and sandbags. Sand for sandbags can be obtained at:
  • City Corporation Yard – 1265 N Milpitas Blvd.
  • Milpitas Sports Center – 1325 E Calaveras Blvd (NW corner of parking lot, open 24-hours a day).
  • Hall Memorial Park  – Parking Lot Cross Street Lattonda and Hermina Street (M-F 7a.m. – p.m).

All  locations are self-service stations. Residents must bring their own shovels.  Sandbags are provided, however they do run out.  Sandbags can be purchased at hardware/home improvement stores.

  • Construct barriers to stop floodwater from entering the building.
  • Keep rain gutters and drainage channels free of debris.
  • Know your neighborhood streams and drainage channel locations (learn more about local watersheds and our creeks and rivers at Santa Clara Valley Water District Watershed Information page
  • Learn how to turn off house utilities. Keep your car’s gas tank full.
  • Purchase flood insurance.


  • Monitor the level of water the street or flood control channel.
  • Be aware that flash flooding can occur. If a flood is imminent, avoid low-lying areas and seek shelter in the highest area possible.
  • Stay tuned to the radio (RADIO MILPITAS 1620 AM) or TV (Channel 15) for emergency information.
  • 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. Turn off gas only if you smell gas.
  • If advised to evacuate, do so immediately.
  • Evacuation is easier and safer before flood waters become too deep. Be especially cautious at night.
  • Moving water is dangerous. Six inches of moving water can make you fall. If you have to walk in water, walk where it is not moving. Use a stick to check the firmness of the ground in front of you and to aid in balance. Visit the National Weather Service for more information on staying safe during a flood
  • Do not drive into flooded areas. If floodwaters rise around your car, abandon the car and move to higher ground. A foot of water will cause many vehicles to float. Two feet of rushing water can carry away most vehicles, including SUVs and pick-ups.
