(a) Corner Setback. At least 100 square feet of sidewalk area or pedestrian-oriented open space (in addition to the otherwise required building setback) shall be provided to achieve a 12.5-foot-wide sidewalk (see illustrations contained within these standards). Upper stories may or may not be set back from the corner.

(b) Corner Entrance to Courtyard, Building Lobby, Atrium or Pedestrian Walkway. New buildings may satisfy the building corners requirements by providing a direct walkway or entry from the building corner to:

(c) Corner Architectural Element. New buildings may satisfy the building corners requirements by including one or more of the following elements that are symmetrical about an axis running diagonally from the corner of the building and bisecting the angle formed by the two building exterior walls:

(a) Metal siding, metal screening, plastic, plywood, sheet wood products or fiberglass shall not be used to cover over existing exterior walls. Wood shall not be used to cover over existing brick or cast stone masonry.

(b) If metal siding is used to cover more than 25 percent of a new building’s exterior walls, such siding must have a matte finish in a neutral or earth tone shade such as buff, gray, beige, tan, cream, white or “dulled” color such as barn red, blue gray or burgundy. If metal siding is to be used to cover more than 25 percent of the exterior walls, the building design must include:

(c) If concrete blocks, tilt-up, poured concrete or precast concrete are used for walls that are visible from a public street, the construction must be treated in one or more of the following ways:

(d) The following building materials on buildings in LI zoning are prohibited where they would be visible from a public street:

(a) Gutters and downspouts must be concealed unless they are designed as continuous architectural features. Exposed gutters used as architectural features shall be colored to match the roof trim or exterior wall (unless copper is used). Exposed downspouts must either match the color or be complementary to the exterior wall to which they are attached (unless copper is used).

(b) All flashing and sheet metal shall be colored to match the surface to which they are attached.

(c) All vents, stacks and pipes shall be colored to match the roof or exterior wall from which they project and are to be grouped so as to minimize the effect of roof penetrations.

(d) All antennas are restricted to the attic or interior of the building. Satellite dish antennas more than three feet in diameter are prohibited. (Antennas required in the performance of public safety or other governmental services are exempt.)

(e) Skylights are to be designed as integral parts of the roof to which they have been installed. Skylight glazing must be clear, solar bronze or gray. White or reflective glazing is prohibited. Skylight framing material must be bronze anodized or colored to match the roof on which the skylight has been installed.

(f) Solar heating panels shall be an integral part of the design of the roof.

(a) Buildings may provide an ornamental molding, entablature, frieze, or other roofline features visible from the ground level. If the decoration is linear molding, the band must be at least eight inches wide (see illustrations contained within these standards).

(b) Buildings may provide a decorative molding or framing around all ground floor windows and doors located on exterior walls facing or adjacent to all public streets. The molding or trim may have a traditional, contemporary, geometric, or sculptural design (see illustrations contained within these standards).

(c) Buildings may include decorative railing, grillwork, or other similar elements. To be considered “decorative,” these elements must include some use of material, geometric pattern, configuration, embellishment, or workmanship that exceeds the normal functional requirements for that element (see illustrations contained within these standards).

(d) Buildings may provide one or more decorative light fixtures. To qualify as a decorative light fixture, the light must meet one or more of the following criteria: (i) have a diffuse visible light source that is nonglaring; (ii) have a decorative shade or mounting that includes some use of material, configuration, shape, embellishment, or detail that exceeds the normal functioning requirement for the light mounting. If the decorative light is a one-of-a-kind or custom built, then one light shall satisfy this requirement. Otherwise, at least one light for every 30 linear feet of building frontage parallel to the street shall be provided.

(e) Buildings may provide any of the following decorative materials to all exterior walls visible from public streets:

(f) Buildings may provide decorative unit paving with at least 50 square feet of multicolored tile, paver blocks, bricks, or other paving in a decorative pattern at the designated front entry into the building.

(g) Buildings may provide a piece of public artwork which may be either freestanding or attached to the structure. It may be in the form of a mosaic tile mural, bas-relief sculpture, water sculpture, fountain, freestanding sculpture, art in pavement, or other similar artwork. Painted murals or graphics on signs or awnings do not qualify as public artwork. All artwork used to satisfy this condition shall be approved by the planning director.

(h) All proposed methods of providing the required building details are subject to the approval of the planning director. Existing buildings that are to receive major renovation or remodeling and which meet the standards listed above in subsections (8)(a) through (8)(g) of this section may be counted toward satisfying these requirements.

(a) When safety concerns or architectural design of the original structure warrant, false and/or “add-on” exterior walls to buildings shall be removed whenever an application is made to renovate such buildings to expose the original architectural detail of the structure.

(b) Storm windows should reflect the appearance and detail of the inner window as closely as possible.

(c) The relationship of the width to the height of new structures should be consistent with that of any existing adjacent buildings. If the site proposed to be developed is large, a variety of design techniques can be used to reduce the potential impact of the mass of exterior walls, including the breaking down of said walls into a number of smaller bays (see illustrations contained within these standards).
