1 It took many hours for workers to shut the water off when a large water pipe broke. Water gushed out of it. The streets flooded. The water pipe that broke was underground. The pressure from the water coming out of the pipe broke the street. The street fell into a huge hole. This break caused a lot of damage. One woman` s car flooded. It had four inches of water in it. There was a lot of work to be done
.
2 Firefighters hope to have control of a big fire by Friday. It has already burnt a lot of land. Firefighters worked all night, their hard work saved a lot of land. Now firefighters are worried. The wind is starting to blow. They think that the winds could fan the flames again. When wind fans a flame, it helps the fire grow. This would be very bad. The firefighters are hoping that the winds do not get any stronger.

3 There was a fire that burnt a house down. The local police are trying to find out how it started. There was a man and three children who are missing. No one knows what happened to them. The mother of the missing children could not find them. She did not know if they were in the home before it burnt. She has not seen the father of her children since the fire. The police are not sure how the fire started. There is nothing that shows that fire was started on purpose but the police want to make sure.

4 In spring, heavy rains and melting snow add a lot of water to the lake behind Folsom Dam. People believe too much water could breach the dam. Then the dam might break and flood the towns below the lake. A flood would be very dangerous for the people who live near the dam. They need to find a solution and a way to keep the nearby towns safe. Senator Deborah Ortiz has an idea that might help. She wants to ask the State of California for funds to make the Folsom Dam seven feet taller.

5 Mr. Baldwin believes the way California handles disasters is a good one. People need to know when there is an emergency. They need to be warned. People can be given warnings over the radio. They are also warned over the television. Mr. Baldwin also says that more work needs to be done in an emergency. One thing he is worried about is how to evacuate people from towns. People need to know where to go if they have to leave
