Signal Hill rides high on the west end, and the streets up there take their pitch seriously — driveways that run downhill fast and lawns you mow across, never up. Louies Lawn Service LLC knows those slopes in both seasons: careful lines in July, salt worked in early in January before anything can glaze on the grade. A hill driveway cleared properly is a small kindness to whoever has to back out of it in the dark. In summer the same attention shows as a level cut and a crisp border along the retaining wall. Belleville and the hills around it — Swansea, Fairview Heights and Millstadt too.
