(A)   Purpose. The architectural design guidelines of this section are intended to preserve historical, cultural, and architectural character and development patterns compatible with new construction and major modifications in order to respect the original architectural character and development patterns within the city.
   (B)   Applicable zones. Facade treatments for metal buildings will be required for properties zoned all Commercial Districts (C-0, C-1, C-2, C-3, CBD), all Residential Districts (R-1, R-2, R-3, and R-4), and Health Facilities District (H-1). The provisions of this section will not apply to properties zoned General Agricultural District (A-1) and Industrial Districts I-1 and I-2.
   (C)   Facade treatments. Facade treatment will be on all facades visible from the street but not to include the rear of the structure. The facade treatment shall cover 100% of the front exterior facing the street, or on a corner lot, the front and side facing the street. The sides will have 25% of the area improved with facade treatment floor (bottom) to deck (top), and shall be constructed using the recommended and acceptable materials listed below in division (D)(3), excluding the window areas.
   (D)   Facade design. All visible building facades shall conform to the following design criteria.
      (1)   Windows and glazing. All facades visible from the street must contain glazed glass windows. Windows shall be recessed and include visually obvious sills. Columns and mullions, shall form spaces between windows or material found elsewhere on the facade. Clear window glass is recommended; green, blue, bronze, or smoke tints are permitted. Window shapes shall be rectangular, square, or Palladian (mostly rectangular with semi-circular top). Glazing shall comply with Chapter 24 or the 2003 International Building Code or the latest version thereof. The maximum permitted reflectance of glass used as a facade material varies depending upon where the glass is used. The reflectance of glass used on the first two stories may not exceed 15%. The reflectance of glass used above the first two stories may not exceed 27%.
      (2)   Building materials. Building materials must be consistent with the surrounding neighborhood character, as determined by the Community Development Director or his/her designee. Building materials on the front facade, or any facade visible from a public right-of-way, must be primarily of natural materials conveying permanence, as determined by the Community Development Director or his/her designee.
      (3)   Recommended and acceptable materials. Brick, stone, wood siding, concrete slab (poured-in-place, tilt-up construction). Split face, scored, or ground face block, or brick veneer, vinyl siding, beveled wood siding (lap, board and batter, shake), stucco, and exterior insulation finish systems (EIFS).
      (4)   Disallowed materials. Metal siding (standing seam panels, aluminum siding, "R" panels), mirrored or reflective glass.
   (E)   Architectural features. These architectural design guidelines are intended to preserve the architectural character while encouraging adaptive reuse of existing buildings, and allowing for compatible new construction and major modifications. Building facades shall contain architectural features, details, and ornaments that are consistent with predominating architectural styles found within the district, such as: arches; roof cornices; contrasting bases; contrasting masonry courses, water tables, or molding; pilasters or columns; corbeling; contrasting bands or color; stone or ceramic accent tiles; colonnades; or porches. Elements such as wall clocks, decorative light fixtures, and door or window canopies are recommended. Architectural features will be consistent with the residential neighborhood or the business area.
   (F)   Compliance. If there is a question as to interpretation of any provision of this section, a written request can be filed with the Community Development Department for administrative review and action. A review can be submitted to the Planning Commission and that decision may be appealed to the Board of Adjustment.
