Fourteen-year-old Gustavo Olivares and his family live in the evacuation area. Many are concerned the levees may not hold.
"My mom she's kind of worried because I don't know where to go and I guess but sometimes she just doesn't think its going to happen but I think I do because I've never seen it this high before," he said.
So the city wants people to be prepared...that's why these mailers were sent out.
Gustavo's father, Carlos Bustamonte, can read it since it's both in English and Spanish.
But both say there was a problem.
"We didn't get this in the mail," Gustavo said.
Melissa Thompson and her family live just south of the 16th St. levee.
While Friday was a nice day for a water fight, Melissa hopes this is all the water she has to combat.
And the mailer?
"We didn't get one," she said. "We don't know the evacuation plan so if something happens we don't know where to go or anything."
One thing people in the area have seen, signs outlining the evacuation route.
They are posted on busy streets and in neighborhoods.
One of the designated gathering spots is at Omaha North High School. Evacuees are instructed to bring a cell phone, any eye glasses or medications they may need, clothing, pets and most import of all, identification so they can get help quickly."
Melissa says maybe the city needed another way to get the information out to those who may be impacted first.
"Maybe have people deliver them door to door," she said. "There's a lot of trailers around here they're not going to get the information."
Gustavo and his family now have an idea of what they need to do.
Both he and his father read the mailer. Gustavo noticed some good tips.
"Like plug the john and stuff and lock your doors," he said.
Now the family can plan ahead and hope they never need to use the information they say they never officially received.
