Saw a long row of beautifully groomed, formal-looking deciduous elm-type-leafed trees surrounding a large commercial building near Seattle. The crowns were all almost identical at about 16 feet tall, maybe 8 feet in width, crown shaped like an oval, unbranched trunks around 6 feet high and perhaps of 10 inch diameters, some had two trunks. Bark was smooth with whitish-colored splotches. It looked like what one might expect to find in an artist's depiction of a large 3 story office building landscaped with such trees.
