Industry
Much of Sioux City's dangerous or polluting industry is located on the downstream side of Sergeant Bluff. This includes two large coal-burning power plants, an ammonia fertilizer plant, and a soybean processor. All of these are in the sprawling Port Neal Landing industrial park, which is surrounded by cornfields and the Missouri River. The terrain here is very flat, because it used to be in the river's flood plain.
