Buildings should be sited to minimize their prominence. When practical, buildings should not be placed at the top of the slope or crest of the hill where they will be seen silhouetted against the skyline and will be visible at a distance. Rather, buildings should be placed down the slope where they will have the hillside for a background. In general, the height of the structures should not exceed the height of the surrounding trees. Buildings should avoid being placed in the middle of open fields, where possible. Rather, buildings should be located in or adjacent to existing vegetation.
