South of downtown, past Southern Hills and the fairways at Singing Hills, Sioux City's newer streets curve wide and gentle compared to the sharp grades up on the bluffs, and a snowfall here tends to lie even across yard after yard of look-alike driveways. Spahn's Property Solutions LLC works that whole stretch of the south side, running a route that covers dozens of driveways in the kind of subdivision where every house went up within a few years of its neighbors. The flatter ground means fewer surprises, but it also means a route has to move fast and steady to get every driveway open before the south side's morning traffic picks up along the arterial streets. A finished route, every drive on the block cut clean to the same width and edge, has its own kind of order to it — one house after another, all open to the road at once. That kind of steady, repeatable route suits a part of the city that was built all at once and expects to be treated that way.
