Building massing. The massing of all buildings shall be de-emphasized in a variety of ways to enhance the visual quality of the development and contribute to a human-scaled environment at the street level. Large buildings shall include vertical and horizontal elements such as facade jogs, towers, balconies, bays, roof gables, and dormers to create the appearance of smaller-scale buildings. All buildings shall feature a proportionate and distinct base, middle, and top. Multistory buildings shall articulate the line between the ground and upper levels with a cornice, canopy, arcade, balcony, material change, or similar three-dimensional visual device.
