Late in the afternoon the light comes off Sylvan Lake sideways and lands on every lawn between the streets and the shore. Elysian Design Group Inc works with that light in mind — mowing patterns that read cleanly from the road, edges cut true along drives and walks, trimming that respects the small sculpted lots this Oakland County city is built from. Spring and fall cleanups keep the ground open and the borders honest. Grass is a surface, and a surface either catches the evening or it doesn't. Theirs does, week after week, all season long.
