Every afternoon the westerly comes up off the bay and the halyards start ringing along the Marina Bay basin. BCA Landscaping Services works into that wind, cutting lawns on the flat streets behind the shoreline where salt air keeps the grass green and the weeds ambitious. Mowing and edging first, then the trimming that squares a bed against a fence line, then everything raked and hauled so the wind has nothing left to scatter. Bay-side yards ask for patience — the breeze takes half the clippings and gives back sand — and the answer is simply going over it again. What stays behind at the end of the round is a lawn holding its shape while the water beyond the path goes silver.
