North Brooklyn runs on brick and water — Newtown Creek at the edge, the Greenpoint rooftops above it, ailanthus and honey locust holding on wherever the pavement allows. Brooklyn Tree Service Pros keeps those yards and lot lines in order, trimming crowns off fire escapes and service lines, pruning street trees until a whole avenue reads even. A removal on a Bushwick lot is a morning of rigging: cut, lower, stack, sweep, and then the sidewalk swept a second time. When a late-August storm crosses the East River and leaves limbs down the length of a block, the work is the same as always, just louder and earlier. The measure of the day is a clean bed of woodchips where a leaning trunk used to stand.
