Move valuable items to upper floors of your home, don’t store them in the basement.
Put large appliances (like washer and dryer), furnaces, hot water heaters and electrical panels up on wood or cement blocks. If you’re unable to do so, consider anchoring these items and protecting them with a floodwall or shield.
Anchor fuel tanks to the floor. A fuel tank can tip over or float in a flood, potentially causing fuel to spill or catch fire. Make sure vents and fill-line openings are above flood levels. Contact the propane company to ask about the best storage methods for propane tanks.
If it looks like water intrusion may occur, shut off the electricity immediately – unless you have a sump pump (you want to keep that working!). Use sand bags or install flood shields or built-up barriers for basement windows and doors.
Prepare a home inventory of your possessions, to make filing a claim easier in the event of damage or property loss.
