Fargo will start building sandbag dikes in backyards next week to prepare for a possible record Red River flood.
Crews will start delivering 1.3 million sandbags to neighborhoods on Tuesday, and volunteers will start building dikes on Thursday. Dike construction is expected to take about four days.
Mayor Dennis Walaker says preparations for the fourth flood in five years are going well.
"There's nothing wrong if the water doesn't get there," Walaker said. "We need to be prepared."
Fargo Deputy Mayor Tim Mahoney said the city must prepare for the worst-case scenario.
"Engineers have everything ready to go, we're going into the neighborhoods and you'll see a lot more activity next week," Mahoney said.
The National Weather Service says the Red River will reach a level between 38 and 42 feet. A more specific forecast will be released when weather conditions warm and the Red River starts flowing.
The record river level in Fargo is 40.8 feet, set in 2009.
