Where any individual commercial building facade is visible from any public right-of-way and exceeds 40 feet in length, there shall be both a clear dimensional differentiation of roofline, and an offset in facade of at least five feet to create effective facades that are no longer than 40 feet. Street trees with tree wells, or other streetscape and pedestrian amenities, shall be used to balance facade offsets. The Township may allow a commercial building with a facade longer than 40 feet if the proposed design emulates characteristic historical building forms such as barns, stables, churches, meeting houses, or other public buildings. Building arrangements which rely on repeated use of the same long facade element shall not be approved. Where an individual commercial building facade exceeds 40 feet in length, the building design or use layout shall limit the length of the streetscape frontage occupied by any one use to the greatest extent practicable by providing for inviting, interior accessory or independent business uses with the streetscape-fronting portion of the building (e.g., the cafe and/or floral operations within a grocery store, or a small, independent service or retail use). In all cases, blank walls, facades, and windows shall be kept to a minimum.
