Sioux Center sits on some of the flattest, most open farmland in northwest Iowa, the kind of ground where a Sioux County wind can pick up a fresh snow off the fields and lay it back down in a drift across a parking lot before the plow even reaches the far corner. Sioux Commercial Sweeping Inc works those big open lots — along Main Street's Dutch-heritage storefronts and around the Dordt University campus — where a single pass has to cover ground measured in acres, not driveways. The same equipment that sweeps a lot clean each summer turns to pushing snow to the edges each winter, banking it in long, even rows along the curb lines instead of scattered piles, so the striping underneath stays visible once the thaw finally comes. A lot cleared corner to corner before the first cars arrive is the whole job, done at an hour when Sioux Center's grid of township roads is still dark in every direction. There isn't much to hide behind out here, and a lot this size either gets cleared corner to corner or it doesn't.
