Height and scale. New commercial or industrial structures shall be compatible with any preexisting building patterns found in adjacent or nearby buildings with regards to massing, height, scale, form and setbacks. The height of new buildings should attempt to coordinate common heights and facade lines with neighboring buildings. In cases where there is a sharp contrast between the massing, height, scale, form or setbacks of immediately adjacent buildings, compatibility with the adjacent buildings of a smaller scale is generally preferred, and a transitional buffer around existing historic properties may be requested by the Planning Board.
