At the southern edge of Brooklyn the wind arrives straight off Jamaica Bay, salted and steady, and the old maples of Marine Park and Bay Ridge have grown a little sideways because of it. Power Tree Removal LLC works those blocks — taking down a leaning trunk over a driveway, trimming limbs back from the eaves, pruning toward a crown that can stand a February gale. Winter storms off the water find the deadwood first, and the storm damage cleanup follows with rakes until the front yard is bare and even. Every removal is planned to the inch, because in this borough the next fence is four feet away. What is left behind is a quiet stretch of curb and a little more sky over the rowhouses.
