Sylvan Lake is a city you can walk across in a few minutes, and nearly all of it leans toward water. The lawns are small and particular — short green slopes running down to seawalls and docks, with fences, corners and stairs everywhere a mower would rather not go. Bruter Landscaping does that patient close work: mowing, hand trimming around the tight spots, edging the walks, and clearing out what spring and autumn leave behind. On a July morning, with the lake still flat, a finished yard on these streets looks like a room that has just been swept. That is the entire point of it.
