Q: Why is it important to ensure your home, garage, storage areas, and carport are waterproof?

A: It is important to waterproof your property because unexpected flooding could happen at any time. Heavy rains can cause flooding that will damage outdoor property such as carports, sheds, and garages. To prevent unnecessary damage, make sure that storage areas are elevated and garage/carport walls are waterproof.


Q: What precautions can you take before a flood or heavy rains?

A: First and foremost, make sure that your family has decided on an evacuation route. Once that is in place, put together an emergency kit with about a week's worth of clean drinking water, clothes, non-perishable food, batteries, and a first aid kit. You should also work to flood-proof your home as much as possible by installing a sump pump and backup power source and adding backflow valves to toilets and drains.


Q: What should you do once heavy rains begin or a flood warning is issued?

A: Once a flood warning has been announced, immediately gather the emergency supply kit and pay attention to the TV or radio for updates. Fill bathtubs, sinks, and buckets with clean water and turn off all utilities. If possible, make sure to bring in any outdoor items such as grills, furniture, and trash cans. Securely tie down large items.
