A.
Applicability. The design regulations of this section apply to all building types in the X Districts, unless otherwise stated.
B.
Intent.
(1)
General. The regulations of this § 475-901, in conjunction with the building types regulations of §§ 475-303 through 475-308, are intended to improve the physical quality of buildings, improve the long-term value and durability of buildings, enhance the pedestrian experience, and protect or establish the character of the Village.
(2)
Durable, high-quality. The minimum design regulations are intended to ensure use of well-tested, high-quality, durable, weather-resistant, exterior grade, preferably natural materials on the majority of finished surfaces, while permitting a wider range of materials for details. High-quality materials can improve the quality of buildings in that they weather well, have a lower failure rate, require a low level of maintenance, have a longer life cycle and sense of permanence, and maintain higher long-term value.
(3)
Simple, well-organized facades. The design regulations are intended to promote simpler, well-organized facades that are easy to comprehend and have a clear hierarchy.
(4)
Human-scaled building units. The design regulations are intended to yield building facade proportions that are comfortable to and in line with the scale of people. Additionally, a high level of detail relates facades to pedestrians and makes them more interesting and inviting.
C.
Major facade materials. At least 65% of each street and nonstreet facade surface, not including window and door areas, must be composed of major materials in accordance with the regulations of Table 9-3.

F.
Materials installation quality. The intent of the materials installation quality regulations is to advance the quality of construction, durability, and aesthetics of new buildings, specifically related to application and detailing of facade materials. Changes in vertical surface materials for buildings must comply with the following regulations:
(1)
Changes in surface materials. Changes in surface materials, whether major materials or minor materials, may only occur at concave corners, minimum 12 inches deep. Surface materials are materials intended to cover the facade surface (such as unit materials, siding, stucco, panels) and do not include detail materials, such as but not limited to cast stone for lintels or cornices, exposed metal beams, or any material used to create a shadow line.
(2)
Materials hierarchy. Unit materials must be elevated from the face of the building above less detailed surface materials. For example, stucco, as a constant surface material, must be recessed behind a bricked surface. See Figure 9-2 for an example, where Material A is brick, Material B metal panels, and Material C stucco.
(3)
Shadow lines on surfaces. Shadow lines must be created at changes in materials with solid materials of a thickness that is greater than two inches, such as cast stone, masonry, or stone. For example, cast stone pieces may be offset to create a shadow where the convex corner of the piece is used to create the corner of the detail.
(4)
Appropriate grade of materials. Except the row building type, all doors, windows, and hardware must be of commercial grade quality.
(5)
Applique materials. Materials with thickness of less than 2.5 inches, including but not limited to stucco, may not be used or formed to create shadow lines.
(6)
Stucco installation. Any stucco construction must be of the highest installation quality and comply with the following criteria:
(a)
All stucco joints must be aligned along the facade in the pattern shown on the elevations submitted for the site plan approval. Joints must also align with the locations of windows and doors and other changes in material.
(b)
The stucco wall assembly must be indicated on the plans specifying stucco type and construction.
(7)
Design exception. Modification to these material installation regulations may be approved through an administrative design exception.
G.
Windows. Windows on street and public way facades of all buildings are subject to the following regulations:
(1)
Amount. Each building must comply with the transparency regulations applicable to the subject building type.
(2)
Recessed. All windows, with the exception of ground-story storefront systems and glass curtain wall systems, must be recessed with the glass a minimum of two inches back, measured from the facade surface material or adjacent trim.
(3)
Vertical orientation. All windows must be vertically oriented except that when a flat building cap is used, horizontally oriented windows may be used for up to 30% of the total transparency area of each upper story.
(4)
Visibility through glass. Reflective glass and glass block are prohibited on street and public way facades. Windows must comply with the transmittance and reflectance factors established in the transparency definition. (See § 475-1502.)
H.
Shutters. When functional or nonfunctional shutters are used on a street or public way facade, the shutters must comply with the following regulations. See Figure 9-5 for examples of shutters.
(1)
Size. All shutters must be sized for the windows, so that, if the shutters were to be closed, they would not be too small for complete coverage of the window.
(2)
Materials. Shutters must be wood, metal, or fiber cement. Other synthetic and engineered woods may be approved through an administrative design exception, provided that the applicant submits a sample and examples of high-quality, local installations of the material, located within 100 miles of the site.
I.
Awnings, canopies, and light shelves. Awnings, canopies, and light shelves on all buildings must be constructed in accordance with the regulations of this subsection. See Figure 9-4 for examples of awnings.
(1)
Encroachment. Detachable awnings and canopies may encroach upon a required setback to within one foot of a lot line, but may not extend into a right-of-way or easement.
(2)
Attached awnings and canopies. Awnings and canopies that are attached to the building and removable are subject to the following regulations:
(a)
Material. All awnings and canopies must be canvas or metal. Plastic awnings are prohibited. Other materials may be approved with an administrative design exception.
(b)
Shapes. Waterfall or convex, dome, and elongated dome awnings are permitted only when approved as an administrative design exception in accordance with § 475-1107.
(c)
Lighting. Backlit awnings are prohibited.

J.
Balconies. Balconies on a facade facing any street, courtyard, open space, or public way must comply with the regulations of this subsection. See Figure 9-6 for examples of balconies.
(1)
Definition. For the purpose of this subsection, "balconies" must include any roofed or unroofed platform that projects from the wall of a building above grade that is enclosed only by a parapet or railing. This definition does not include false balconies, juliet balconies, or balconettes.
(2)
Balconettes. Sometimes referred to as juliet balconies, balconettes are false balconies consisting of a rail and door, either without an outdoor platform or with an outdoor platform less than 18 inches in depth. Balconettes are permitted and do not count towards the maximum permitted amount of balcony on a street facade.
(3)
Size. Balconies must be a minimum of four feet deep and five feet wide.
(4)
Integrated design. Balconies are intended to be integrated with the design of the facade, avoiding tacking the balconies onto the facade after the elevation has been designed.

(b)
Horizontal shadow lines and lintels over openings may be used to delineate stories with minimum shadow lines as required for the subject building type.
(c)
Mezzanines that fall within the range of floor-to-floor heights of the building type must be articulated on the facade and require separate calculation for transparency.
(d)
Spaces exceeding the allowable floor-to-floor heights of the building type must be articulated as multiple stories on the street facade.
M.
Arcade design. See Figure 9-8 for an illustration of an arcade. The following requirements apply to arcades. An arcade is a covered pedestrian walkway within the recess of a ground story.
(1)
Depth. An open-air public walkway must be recessed from the principal facade of the building a minimum of eight feet and a maximum of 15 feet.
(2)
Build-to zone. When an arcade is used, the outside face of the arcade is to be construed to be the front facade, located within the required build-to zone.

(1)
Rears of buildings. The location of open space and streets may not create views of the rear of buildings or parking behind buildings.
(2)
Parking. Parking structures and surface parking lots are not permitted at the termination of a street vista.
(3)
Street termini. When a street terminates at a parcel, the parcel must be occupied by open space or a building, as follows:
(a)
If the parcel is open space, a vertical element must terminate the view. Acceptable vertical elements include, but are not limited to, a stand or group of trees, a sculpture, a gazebo or other public structure, or a fountain.
(b)
If the parcel is not used as an open space, the facade of a building, whether fronting a primary street or not, must terminate the view. The building must incorporate a tower, a bay or a courtyard to terminate the view.
O.
Garage doors. The following requirements apply to garage doors provided on any street facade.

(d)
When the elevation of the first floor is more than three feet above grade, windows should be provided into the basement or lower floor elevations.
Q.
Mechanical equipment and appurtenances. Mechanical equipment and appurtenances can have a negative visual impact and detract from the quality of the design of a building. The purpose of these regulations is to ensure that the visual impact of mechanical equipment and appurtenances is minimized. See Figure 9-9 for illustrations.
(1)
Mechanical equipment in building. Mechanical equipment must be located within the building, unless the applicant demonstrates the equipment is necessary for the function of the building and locating the equipment within the building would conflict with the equipment's function.
(2)
Rooftop mechanical equipment. Any rooftop mechanical equipment, such as but not limited to vents, ducts, condensers, and ventilators, and not including solar panels, must be located consistent with one of the following methods:
(a)
Incorporate equipment into the roof design consistent with the applicable building cap regulations of § 475-309.
(b)
Set the equipment back a minimum of 20 feet from any street or public way facade.
(c)
To the extent practicable, all rooftop mechanical must be painted to blend with the structural roof and limit its visibility.
(d)
Rooftop mechanical equipment visible from adjacent highways must be screened with materials consistent with the building design.
(3)
Mechanical equipment and utility appurtenances on facades. Mechanical equipment and utility appurtenances may not be located on a facade unless the applicant demonstrates that locating the equipment in a different location would conflict with the equipment's function. Any equipment or appurtenance approved on a facade, such as dryer vents, gas meters, and air conditioners are subject to the following regulations:
(a)
The mechanical equipment may be located on a primary facade only if the following requirements are met:
(b)
Multiple pieces of mechanical equipment must be organized on the facade in a regular pattern and aligned. Compliance with this regulation must be illustrated on the drawing elevations submitted as part of the application.
(c)
To the extent practicable, facade-mounted mechanical appurtenances must be located on a material that limits their visibility. For example, dark colored vents will be more visible on light colored stucco than a textured, darker surface such as brick.
(4)
Mechanical equipment and utility appurtenances on other horizontal surface. Mechanical equipment and utility appurtenances located on the ground, decks, or horizontal surfaces other than the roof (e.g., electrical equipment and air conditioners) are subject to the following regulations:
(a)
No encroachment. Mechanical equipment may not extend into any Village right-of-way or easement.
(b)
Yard location. Mechanical equipment may not be located in a front or street side yard.
(c)
Screening from streets and civic spaces.
[1]
All equipment must be screened from view from any streets, open space, or civic space with landscaping, fencing, or walls consistent with the building design, colors, and materials.
[2]
Where landscaping only is employed, a single row of evergreen shrubs must fully screen the equipment within one year of installation. The Planning Director may require additional landscape materials. See § 475-903 for landscape regulations.
[3]
Where landscaping is employed, the utility must be located in a larger landscape area and the landscape screen must be designed as part of the bed design.
(5)
The Planning and Zoning Administrator is authorized to approve appurtenances located on a primary street only if the following conditions are met:
(a)
The applicant demonstrates that the equipment cannot be located in a rear yard, nonprimary street yard, or in a side yard.
(b)
No utility cabinets, boxes, or other appurtenances are within 200 feet along the same side of the street as the proposed utility appurtenance.
(c)
The appurtenance is fully screened in a manner that is consistent with the building design, colors, and materials and of a height that is the minimum to adequately screen the appurtenance and that does not prevent the facade from fulfilling any transparency requirements. See Figure 9-14 for examples of poorly located, unscreened equipment on primary streets.
(d)
The appurtenance is located a minimum of 35 feet from a street intersection, measured from the intersection of the curbline, and does not impact the sight vision clearance at intersections.
(6)
Design exception. An administrative design exception may be requested for an alternate mechanical equipment location and screening design.
