Footnotes to the Table of Acceptable [Exterior] Wall Materials.
(1) Does not include facade areas consisting of doors and windows.
(2) All walls exposed to public view from a public street, alley or an adjacent residential area must be constructed of not less than seventy-five percent (75%) brick, face brick, stone or cast stone.
(3) Includes flat sheets and seamed or ribbed panels, including aluminum, porcelain and stainless steel and similar material. Such materials cannot be used where contact with vehicles may occur, such as parking areas, traffic ways, and loading areas, unless such walls are adequately protected to prevent damage.
(4) Includes fiberglass, reinforced decorative stamped, colored concrete, polymer plastic (fypon), exterior insulation and finishing systems (EIFS), plaster, stucco and similar materials. The Zoning Administrator (or designee) may increase the percentage of wall that can be clad in finishes if they are designed to mimic the appearance of another approved finish (e.g., EIFS designed to look like cut stone) or other embellishments are added to the building facade (e.g., window and door trim, cornices, etc.), per the criteria set forth in subsection (c)(4) of this section. Such materials cannot be used where contact with vehicles may occur, such as parking areas, traffic ways, and loading areas, unless such walls are adequately protected to prevent damage.
(a) Material used in the C-3 district shall match the historical characteristic of the district.
(5) Cast stone, including lightweight artificial stone products, must complement other materials found in the surrounding area and be approved by the and Zoning Administrator (or designee) upon the review of building facade elevations submitted by the applicant.
(6) A maximum coverage of fifty (50) percent burnished concrete block is permitted in the C-4, M-1, and M-2 districts only upon special approval from the Zoning Administrator (or designee) where the applicant demonstrates special conditions that limit use of other materials and demonstration that other site and building design enhancements are provided. The height limit for burnished concrete block is six (6) feet.
(7) Parking structures may use precast concrete or concrete formed in place if approved by the Zoning Administrator (or designee) upon the review of building facade elevations submitted by the applicant.
(8) Decorative metal and other embellishments may be used if approved by the Zoning Administrator (or designee) upon the review of building facade elevations submitted by the applicant.
(9) Must be clapboard, cedar shingles, or similar materials approved by the Zoning Administrator (or designee) upon the review of building façade elevations submitted by the applicant. Any grade of plywood, oriented strand board (OSB), T-111 siding, and similar materials are strictly prohibited on any portion of a structure because they are not finished building materials and do not under any circumstances weather like the other reference exterior/wall materials.
(10) The exterior wall of the office area of an industrial structure shall consist of any mixture of material permitted in the C-4 zoning district or other materials approved by the Zoning Administrator (or designee).
(11) The preferred product is a cementus material.
(12) Siding may not protrude beyond a window or door casing except under special circumstances which shall be approved at the discretion of the Zoning Administrator.
(c) Allowance for Other Materials. The Zoning Administrator (or designee) may waive strict compliance with the subsection (b) of this Section when the qualities listed below can be demonstrated. Review and consultation by the appropriate design professional is encouraged before a final determination is made. The proposed building design and materials schedule must be accompanied by a written design statement which describes how the selected wall materials and material combinations will be consistent with and enhance the building design.
(1) The design and materials are found to be in keeping with the character and history of the neighborhood or other area of the city;
(2) The materials are found to be permanent and durable;
(3) The design and materials are compatible with the type of use and development proposed;
(4) The design and materials can easily be adapted to another use in the future; and
(5) The design and materials meet the intent of this section.
(d) Mixture of Materials. The application of these standards promotes integration and mixture of materials where more than one (1) material is used on a building. If only one (1) material is used, architectural detailing and articulation, massing, texture and form must be introduced into the building design, unless otherwise specified in the Table of Acceptable Exterior Wall Materials (see subsection (b) of this Section). Building roof materials must be in harmony with the style and materials used on the building walls.
(e) Long Walls. When building walls are seventy-five (75) feet or greater in length, design variations must be applied to assure that the building is not monotonous in appearance. Such variations include but are not limited to the following:
(1) Recesses and projections along the building facade, which must be a minimum of one (1) foot in depth;
(2) Architectural details or features;
(3) Enhanced ornamentation around building entryways;
(4) Landscaping for which size, species, and number are acceptable to the Zoning Administrator;
(5) Streetscape elements; and
(6) Variations in building height.
