How to be prepared for floods

BEFORE• Determine your flood risk. Know whether

or not you live in a flood prone area. Call the flood inquiry telephone line, check the FEMA flood maps.

• BUY FLOOD INSURANCE

• Make a family disaster response plan which includes a flood response plan. Plan should include:

• A place to meet in case of evacuation

• List of phone numbers of family members

• Prepare a family disaster response kit which includes:

• Portable radio, emergency cooking equipment, flashlights, fresh batteries, non-perishable food and drinking water, essential medicines and a first-aid kit in a water proof container.

BEFORE• Prepare your house pre-flood by:

• storing valuables safely in a high place such as the attic

• store house hold chemicals high above the ground

• close storm shutters

• move vehicles to a higher elevation

• turn off main gas valve

• turn off the main power switch [Do not touch any wet electrical equipment]

• keep storm drains near your home clear.

DURING• Follow instructions given to you by emergency

management officials from a local station on your battery powered radio.

• Do not linger outside in areas where rapid flooding is a threat.

• Be prepared to evacuate.• If driving do not drive when the water is completely

covering the road. If your car stalls, leave the car and reach safe ground.

AFTER

• Record damage by taking photos.

• Contact Flood Insurance.
