How to protect your home  

From a Flood!
Floods happen - beside rivers, on the coast, in deserts, along city streets and behind protective levees. But you can take steps before the flood to protect your home and family from disaster. Some things can and should be done immediately. Others require a licensed professional. However, each change you make will increase your home’s resistance to flood damage.
When there is risk of flood:
Clear drains, gutters and downspouts of debris and make sure your yard’s grading (slope) directs water away from the building.
Anchor fuel tanks. An unanchored tank can be torn free by floodwaters, and the broken supply line can cause contamination, or if outdoors, can be swept downstream and damage other homes.
Buy and install sump pumps with backup power where needed. Regularly check to make sure they are working.
Cut off electrical service at the main breaker if the electrical system and outlets will be under water.
If you have time to hire a licensed electrician:
Raise electric components (switches, sockets, circuit breakers and wiring) at least 12” above the projected flood elevation.
Place all appliances, including furnace, water heater, washer and dryer on masonry blocks or concrete at least 12” above the projected flood elevation.
If you have time to hire a licensed plumber:
If flood waters enter the sewer system, sewage can back up and enter your home. To prevent this, install an interior or exterior backflow valve. Check with your building department for permit requirements.
After the flood:
As soon as it is safe to do so, disconnect all electronics/electrical equipment and move it to a dry location.
Remove as much standing water as possible from inside the building.
Begin to remove water-damaged materials immediately.
Ventilate with fans and/or dehumidifiers.
Acting quickly can increase the chance of salvaging usable materials, reduce the amount of rust, rot and mold that might develop, and limit the likelihood of structural problems.
