Lopez Landscaping, Inc. keeps its hands in the ground of Westbrook, where the Presumpscot River bends past old brick mills and the falls throw up their spray. Through the warm months the crew coaxes lawns into that even, close-cut green that catches the low river light of a Maine evening, edging the walks until every line runs true. When the cold settles over the Presumpscot valley and the driveways go white and silent, the same hands are out before the streetlamps blink off, scraping the snow back to bare pavement so the day can begin. It is plain, honest work — a mowed yard that holds through August, a drive cleared before the first commuter stirs — and it leaves its quiet mark on this river town.
