The city of Coppell is warning hundreds of people that their homes could be in danger of flooding.
Police officers went door to door Thursday evening to urge people to protect valuable personal property before going to bed. [[308427481,C]]
Water from Grapevine Lake is spilling uncontrolled into Denton Creek and being carried to the Elm Fork of the Trinity River System.
Emergency officials said water levels in Denton Creek and the Elm Fork could rise another four to seven feet.
Lake Grapevine is forecasted to crest late Friday just before midnight, which will force twice the amount of water over the spillway, according to Clay Church with U.S. Army Corps of Engineers.
Officers were posting flyers on many residents' doors reminding them that water can rise quickly, and people should call 911 in an emergency.

The latest news from around North Texas.
Coppell resident Blake Jackson said he has never seen the water behind his house reach this high.
"It's normally about 20 feet, 15 feet away from the steps is where the pond ends," he said.
The neighborhood pond is now filled to overflowing with water from a swollen Denton Creek, and the flood waters are threatening many homes.
"It's coming to the height of our stone wall, and I think it's going to come into our yard here shortly. We've got, what, about four inches until it's going to be into our yard," said Coppell resident Ann Jackson.
At Lake Grapevine, enough water to fill an Olympic-sized swimming pool comes over the spillway every 10 seconds.
The highest flood waters are expected to reach Coppell two hours after the lake crests.
The U.S. Army Corps of Engineers continues to watch the rising water closely, joined by city leaders from Grapevine.
"Our lake parks are closed, we have roads that are closed, so a situation that was pretty bad got worse, honestly," said Grapevine City Manager Bruno Rumbelow.
With the first day of summer on Sunday, recreation areas will stay closed from some time.
"Last summer we had complaints from individuals about not enough water in the reservoir. This summer is the exact opposite, too much water," said James Murphy, with the U.S. Army Corps of Engineers.
Now, Jackson and her neighbors are anxiously watching the water.
"I'm just going to pray and hope our home doesn't get flooded," she said.
