The city of Omaha is expected to apply for federal disaster aid following intense flash flooding over the weekend that collapsed some sewers and sent floodwaters into businesses and homes. The Omaha World-Herald reports that city officials have been tracking growing expenses from the storm damage and expect to meet the threshold to apply for federal aid. Officials have not yet released other details about the expected disaster declaration. The storm that dropped torrential rains on the city and surrounding communities Saturday night was second this summer to prompt the pursuit of federal disaster aid money. In July, a hurricane-force windstorm knocked out power to 188,000 Omaha Public Power District customers.
