The Hudson goes pewter at the end of a Yonkers afternoon, and the hills above it hold more canopy than the city gets credit for — sycamores over Warburton, oaks leaning off Nodine Hill, old maples crowding the wires along streets laid out for horses. Yonkers Tree Removal Service takes the tight ones: a removal in a yard the width of a driveway, a crown lifted off a roofline by rope and hand. Pruning here is arithmetic, how much to take so the tree still reads as a tree and the sidewalk still gets its shade. After a nor'easter comes up the river valley and lays a limb across the front steps, the branches go, the brick gets swept, and the block looks like nothing happened. Untermyer's terraces set a high mark for what green can do in this city, and the rest of Yonkers deserves the same care, one yard at a time.
