Down by the waterfront the wind off Mount Hope Bay keeps the grass moving and the air a few degrees cooler than it is up the hill. Shepard Group, Inc. keeps lawns across the city on a steady cadence — mowing on schedule, trimming the edges, cutting a clean border along walks and drives, and running the cleanups at both ends of the year. Fall River properties come in every shape, wedged between driveways or spread across a corner lot, and each one gets the pass it needs. The aim is a place that looks composed from the street and comfortable from the back step. Simple work, done on time, is what adds up to that.
