Coping with Floods
Floods are the most common and widespread of all natural disasters, except fire, and are the number one weather-related killer in the United States. Types of flooding are often announced by local TV and radio stations. Flood warnings and watches should be taken very seriously. Flash floods are a result of heavy, intense rainstorms dropping large amounts of rain within a brief period of time and usually occur within 6 hours of the rain event. Soil conditions, ground cover, and topography can also play a role in contributing to flash flooding. Flooding is normally a longer-term event and may last several days or weeks depending upon how much rain has fallen over several days. Urban Floods occur when land, converted from fields or woods to roads, parking lots, or driveways, loses its ability to absorb rainfall. Runoff in urban areas is two to six times greater than on natural terrain. During urban flooding, streets can become swift-moving rivers, while basements can fill up with water.

Before the Flood - Things You Can Do
There are a number of things you can do before a flood occurs to lessen the impact:
- Install a sump pump or check your sump pump.
- Keep the sump pump and pit clean.
- Make sure the discharge hose delivers the water several feet away from the house to a well-drained area that slopes away from your house.
- Do not pump or drain into the sanitary sewer system.
- Make sure gutters and downspouts drain properly and water is directed well away from the house.
- install extensions (available at hardware stores).
- Never connect a downspout drain to the sanitary sewer.
- Keep water out of window wells.
- Contour the ground so water will naturally drain away from the house.
- Contour the ground so water will naturally drain away from the house.
- Keep items you consider valuable or irreplaceable (photo albums, personal videos, tax records, insurance policies, etc.) somewhere other than the basement.
- Store basement items one foot off the floor.
- If you have experienced flood waters entering the basement, raise your furnace and water heater off the floor.
- Have a backflow prevention device installed in the building's sanitary sewer line (lateral line), either inside or outside of the building structure .... OR
- Install a floating floor-drain plug in the floor drains which will allow water to drain.
- When the floor drainpipe backs up, the float will rise and plug the drain.
