In the first picture, one can see the top half or so of the contemporary. When considering where the "berm" would be allegedly built, it would not shield the contemporary from liberty square. It's just simply too far away unless the berm is as tall as at least half the height of the contemporary. If they were building a berm of building closer to liberty square, you could accomplish the screening effect with a structure as short as 20 or 30 feet. The "berm" or screening device, must get progressively taller as it gets further from the viewer, and closer to the object that is desired to be screened, to the point of it being as tall as the object being screened.
