Lake Avenue runs like a green tunnel through Saint James, and by December it has gone bare and blue-dark long before anyone is awake. That is the hour Barry Bros Landscape Design LLC is out with the plow, opening driveways so the first car of the morning meets clear pavement instead of a wall of white. By May those same streets ask for something else entirely — mowing in a straight line, trimming tight to the fence posts, an edge cut sharp enough to hold a shadow. Cleanups bracket the season at both ends, hauling out whatever the North Shore leaves behind in April and again in November. Saint James takes its weather off the Sound, generous with both rain and snow, and the work follows accordingly.
