Half a square mile, and every yard in Prospect Park has a neighbor close enough to notice. P. Park NJ, LLC takes that as the working standard: mowing on a set schedule, string trimming right up to the foundation and the fence, cutting the edges along walks and driveways, mulching the beds, and gathering leaves once the street trees drop them. Lots are small here and shaped by the hill, so the detail work gets done by hand where a machine would be careless. The season opens with a cleanup that clears out the winter and closes the same way in November. By a June evening the block looks like somebody kept their word.
