Officials in the Omaha area are re-evaluating the city’s flood-control measures, shortly after heavy rains caused dozens of counties and cities in the state to declare a state of emergency.
A flash flood event caused by heavy rain in the Papillion Creek Basin is Omaha’s biggest flooding vulnerability, John Winkler, the general manager of the Papio-Missouri River Natural Resources District, told the Omaha World-Herald. About a third of Nebraska’s population lives in the area.
Heavy rain in the northern part of the basin, followed by more in the southern part of the basin would trigger a flood, Winkler said.
“That’s what would overwhelm us,” Winkler said.
