<br />Slide C20. Scenic river road in northern California <br /> <br />Scenic roads like this one in northern California, as well as busy interstate highways, <br />often follow the course ofrivers and streams. Floodwaters can overrun the roads, wash <br />out sections, and leave them impassable for days and weeks after a flood. <br /> <br />Slide C21. Submerged bridge <br /> <br />Bridges are a critical lifeline in many cities tying two parts of a community together or <br />providing an essential link to the outside world. This shows a bridge in the Midwest <br />submerged by flooding in 1979. People living in the houses in the background are now <br />cut off from the other side of the river. <br /> <br />Slide C22. Sewage treatment plant during flood <br /> <br />Water and sewage systems are especially vulnerable to flood damage. This shows a <br />sewage treatment plant which just escaped flooding because it is elevated on fill. <br />Treated sewage is typically discharged into the nearest body of water. This means that <br />treatment plants are usually located in floodplains next to rivers or streams. Damage to <br />the plants often means that untreated sewage is discharged into the floodwaters leading <br />to potential health hazards and pollution problems. <br /> <br />Slide C23. Water pumping station in Hull, Illinois <br /> <br />Other utilities are also vulnerable to flood damage. This shows a water pumping <br />station in Hull, Illinois, protected by sandbags from flooding in 1993. Without the <br />emergency sandbagging, the community would have been without water. <br /> <br />Slide CU. Unlabeled drum on Mississippi River <br /> <br />Floodwaters and hazardous materials don't mix well. This shows an unlabeled drum <br />floating down the Mississippi River near Hannibal, Missouri. The dilemma for <br />emergency responders in situations like this is deciding what to do. The drum could <br />carry explosive or toxic materials, posing an additional danger to riverside communities <br />already faced with flooding. All tanks and drums holding hazardous materials must be <br />labeled and tied down. <br /> <br />Slide C25. Now begin Task C. <br /> <br />Now it's time to begin Task C and create your own flood damage scenario. You have 45 <br />minutes to complete this task. <br /> <br />Reminder to Facilitator: Be sure to set the timer for 45 minutes. <br /> <br />Script-Task C, page 5 <br />
