DAVENPORT, Iowa (AP) - A new report released by the U.S. Army Corps of Engineers says an April flood barrier breach in downtown Davenport was caused by pressure from the swollen Mississippi River shifting a barrier with slick plastic sheeting under it.

The report, released Tuesday to Davenport city officials, says the sheeting became slick in the wet conditions, and a segment of the barrier overturned.

City officials say the public works department will make changes to its flood plan based on the report, including making changes to plastic sheeting installation and double-stacking flood barriers when the river height is forecast to reach 20 feet or higher.

Officials in the eastern Iowa city had already announced plans to build a bigger flood barrier in the wake of the April breach that sent floodwaters rushing into downtown streets.
