This is an example of "implied privacy" Instead of a rather drab, single-file row of evergreens, typically used when screening is the issue, the strategically placed spruces and deciduous trees, along with the high berm, create a sense of privacy without creating a feeling of being walled-in. Over time, the trees will fill-in, totally shielding the backyard from street traffic and prying eyes, while still offering an exciting view from the back porch.
