If the length of any elevation is greater than 100 feet, it shall have incorporated into the wall plane at least two projections or recesses with a depth of at least three feet and a width of at least 20% of the facade length. If the length of any elevation is greater than 150 feet, it shall have incorporated into the wall plane at least two projections or recesses with a depth of at least five feet and a width of at least 20% of the facade length. If the length of any elevation is greater than 250 feet, it shall have incorporated into the wall plane at least three projections or recesses with a depth of at least five feet and a width of at least 20% of the facade length. Flat roofs shall feature articulation that coincides with the wall plane articulation. For the purposes of administering and enforcing this chapter, an awning shall not constitute a facade projection. The ARC may approve wall plane recesses and projections designs that do not meet the above noted minimums; however, under no circumstance shall the ARC approve a wall plane design that does not include any projections or recesses, unless the wall planes are less than 50 feet in length.
(g) All commercial buildings of 15,000 square feet or less shall incorporate four-sided architecture.

(h) Integrate at least one material change, color variation, or horizontal reveal for every floor of a building facade (greater than two stones); vertical spacing may be averaged over facade. On such buildings, the first floor facade shall appear to be greater than the other floor heights. Integrate at least one material change, color variation, or vertical reveal every 50 horizontal feet of building facade (greater than 15,000 square feet); horizontal spacing may be averaged over facade elevation. All buildings, regardless of size or number of stories, shall use scale and design elements, such as but not limited to special lighting, awnings, trees, and other elements, to visually relate the building to the pedestrian scale and visually anchor the building to the ground/street level. Exceptions may be granted by the ARC for buildings featuring architectural styles which lend themselves to less variation.
(i) For at least 60% of the building foundation perimeter, use any combination of concrete, stone, or unique variation of color, texture, or material, at least ten feet in height, around the base of the building. Buildings may alternatively incorporate other architectural features such as ledges, facade reveals, ground level fenestration, raised planters, or landscaping elements within three feet of finished grade.

Roof-mounted equipment shall be screened from the view by parapets, dormers, portion of roof, or other screens. The material of all such screens shall be consistent with the exterior materials used on the facade of the primary building, unless use of such material is deemed not logical or feasible by the ARC, in which case the ARC may approve an alternative material. All roof-top equipment screens shall be constructed so that the equipment screen fully obscures the view of the equipment from all points of abutting property lines and all points of the farthest right-of-way line of any adjacent public or private street. The line of site measurements shall be taken at a height of eight feet from grade along the applicable property line or right-of-way line. The town may require multiple line of site exhibits depending upon existing or proposed conditions, including but not limited to distance from equipment and changes in grade. Mechanical and utility equipment not shown on plans (due to unknown location or other reasons) or mechanicals added that were not originally planned for do not remove the developer's responsibility to comply with these standards.
