Floods

What is a flood

A flood is retention of water in the landscape due to excess rain that occurs in low-lying areas and/or near watercourses that can lead to water overflow. Flash floods can occur when a storm moves slowly, so that a small area receives most of the rain, but the drainage and runoff characteristics on the ground can also determine the area of greatest impact. (Remember, flood damage is not usually covered by insurance.)

What can you do to prepare for floods

Ask your council about local flood plans which detail problem areas and evacuation routes and centres;
If your area is flood prone, consider alternatives to carpets (eg removable rugs and tiles); and
Prepare an emergency kit (emergency phone numbers, portable radio, torch, spare batteries, first aid kit, strong plastic bags for clothing, valuables, and plastic sheets, timber strips, hammers and nails for temporary repairs).

What can you do when you hear a flood warning

Listen to your local radio station for severe storm advice and warnings;
Plan to move vehicles, outdoor equipment, garbage, chemicals and poisons to higher locations;
Plan which indoor items you will raise or empty if water threatens your home (e.g. freezers and refrigerators); and
Check your emergency kit and safeguard your pets.

What to do if you need to evacuate

Pack warm clothing, essential medications, valuables, personal papers, mobile phone, photos and mementos in waterproof bags to be taken with your emergency kit;
Raise furniture, clothing and valuables on to beds, tables and into roof spaces;
Empty freezers and refrigerators, leaving doors open;
Turn off power, water and gas;
Whether you leave or stay, put sandbags in the toilet bowl and over all laundry/bathroom drain holes to prevent sewage back-flow;
Lock your home and take recommended evacuation routes for your area; and
Don’t drive in water of unknown depth and current.

What do you do if you stay or on your return

Listen to your local radio station for official Advices and Warnings;
Don’t allow children to play in, or near flood waters;
Avoid entering floodwaters. If you must, wear solid shoes and check depth and current with a stick;
Stay away from drains, culverts and water over knee-deep;
Don’t use gas or electrical appliances which have been in flood water until checked for safety;
Don’t eat food which has been in flood waters; and
Boil tap water until supplies have been declared safe.
