Federal Hill stands over Bloomingdale like a held breath, and from its rock you can see how the borough's lawns are stitched into the hillsides in narrow, hard-won green. Blueprint Exteriors LLC mows those slopes through the long afternoons of July, when heat settles into the hollows and a mower has to be walked as much as ridden. Edging is where the work shows — a clean line where turf meets driveway, cut so the eye follows it all the way to the street. Trimming around stone walls and the outcrops the Highlands left behind takes a patience that flat ground never asks for. The result is a lawn that looks like it belongs to the hill it sits on.
