Here is the latest Iowa news from The Associated Press at 3:15 a.m. CDT

CEDAR RAPIDS, Iowa (AP) — Nearby communities are donating several thousand filled sandbags to Cedar Rapids as the city prepares for flooding. Waterloo and Cedar Falls endured the crest of the Cedar River Saturday evening. So on Sunday those cities sent their extra sandbags about 55 miles downriver to Cedar Rapids. Forecasters say flooding is expected to begin in Cedar Rapids Sunday night and reach its height by Tuesday.

TRAER, Iowa (AP) — A single wind turbine was already turning in the breeze several miles away when MidAmerican Energy began work on the Vienna Project, the utility company’s 14th wind farm, in 2012. That one turbine near Traer may not get much attention compared to the Vienna Project’s 45 turbines _ one of the smaller wind farms MidAmerican owns. But that one turbine, on average, powers 40 percent of Traer Municipal Utilities’ energy usage. And it’ll likely be the only one the town of 1,700 ever requires.

DES MOINES, Iowa (AP) — Some of Iowa’s most powerful interest groups along with environmental organizations are backing efforts to clean up the state’s waterways, but there isn’t unity about how to take action on an issue that has frustrated lawmakers in the past. Two new coalitions have offered very different plans for tackling the problem, with one backing an increase in the sales tax and another supporting a moratorium on livestock confinement operation. Gov. Terry Branstad has rejected both of their proposals.

OMAHA, Neb. (AP) — Music, food trucks, skateboarding and more could soon come to the Missouri River area. A new committee backed by the Greater Omaha Chamber of Commerce has formed to do the nitty-gritty work of implementing a bold vision for the riverfront area in Omaha and Council Bluffs. It’s working off a blueprint developed by a group of outside experts from the Urban Land Institute.
