FIGURE 202.04J1c: WALL PLANE ARTICULATION

d. Building Articulation. Commercial building facades shall include building projections or recesses, doorway and window trim, and other details that provide architectural articulation and design interest.

e. Exterior Building Materials and Colors:

(1) A unified palette of materials and colors shall be used on all sides of buildings regardless of orientation.

(2) Exterior building materials shall be brick, stucco, concrete block, painted wood clapboard, painted metal clapboard or other quality, durable materials approved by the Zoning Administrator.

(3) The building base (bulkhead) shall be tile, stone, brick, concrete, or other comparable durable material; stucco is prohibited.

(4) The exterior use of slump block, board and batten, dark reflective glass, galvanized metal, and wood or composition shingles is prohibited. Colors shall reflect the historic character of Downtown. Fluorescent paints, blues, purple, bright red or orange, pink, and bright green are prohibited on Main Street.

f. Building Entrances:

(1) Buildings shall be oriented to face public streets.

(2) Building frontages shall be generally parallel to streets, and the primary building entrances shall be located on a public street.

Residential Building Design:

a. Residential Architectural Articulation. All multiple-family residential buildings and mixed-use buildings that include residential uses shall include adequate design features to create visual variety and avoid a large-scale and bulky appearance. Long facades shall be broken up into smaller modules. This requirement can be met by using two (2) or more of the following methods.

(1) Facade Articulation. All street-facing facades have at least one (1) horizontal or vertical projection or recess at least four (4) feet in depth, or two (2) projections or recesses at least two and one-half (2.5) feet in depth, for every twentyfive (25) horizontal feet of wall. If located on a building with two (2) or more stories, the articulated elements shall be greater than one (1) story in height, and may be grouped rather than evenly spaced in twenty-five (25) foot modules. Building entrances and front porches and projections into required yards such as stoops, bays, overhangs, fireplaces, and trellises may count towards meeting this requirement.

FIGURE 202.04J2a(1): FACADE ARTICULATION

(2) Variable Roof Form. Variable roof forms incorporated into the building design, and no more than two (2) sideby-side units are covered by one (1) unarticulated roof. Articulations may be accomplished by changing roof height, offsets, and direction of slope, and by introducing elements such as dormers, towers, or parapets.

(3) Facade Detailing and Materials. All visible building facades incorporate details, such as window trim, window recesses, cornices, changes in materials or other design elements, in an integrated composition. Each side of a building that is visible from a public right-of-way shall be designed with a complementary level of detailing and quality of materials.

(4) Use of Balconies, Bay Windows, and Other Such Projections or Recesses. The building incorporates balconies, bay windows, entry porches or other projections and recesses in a pattern that creates architectural interest across the length of the facade.

b. Residential Building Facade and Entrances. The following standards apply to residential buildings and mixed-use projects that include residential uses.

(1) Orientation. All units located along public rights-of-way shall have the primary entrance facing this right-of-way. Exceptions to this requirement shall only be approved for projects where multiple-family housing is located on four (4) lane streets carrying high traffic volumes and/or streets that do not allow on-street parking. In such cases, the project shall be oriented around courtyards.

(2) Street-facing Facades. Street-facing facades of residential buildings shall be designed as front facades and shall include stoops, porches, recessed windows, and bay windows or balconies.

(3) Projection or Recess. Building entrances shall have a roofed projection (such as a porch) or recess with a minimum depth of at least five (5) feet and minimum area of fifty (50) square feet. Alternative designs that create a welcoming entry feature facing the street, such as a trellis or landscaped courtyard entry, may be approved.

(4) Entrances. Provide at least one (1) building entrance for every one hundred (100) feet of street frontage.

K. Mechanical Equipment. Mechanical equipment, including rooftop mechanical equipment, shall be screened from view from eye level at public streets, and the screening shall be designed as an integral component of the architectural design.

L. Utilities Screening. Utility meters and related equipment shall be located only on the side or rear facade of buildings and shall be integrated into the building architecture through painting or other means.

M. Building Security. Components of building security shall be integrated into the building’s design and be effective but not obtrusive in accordance with the following standards:

Security doors shall not encroach into the public right-of-way, in either an opened or closed position.
Lighting shall be provided at all entryways to the building and in any alcoves or other features of the building which impede the ability for visual surveillance of the building and its public areas.
Where security grills are required or otherwise provided, they shall be painted to match the trim colors of the building. Unobtrusive roll-down grilles with thin vertical and horizontal elements are preferred; heavy steel and accordion fold grates are discouraged.
Grilles, security doors, and other security devices designed for nighttime security shall not be readily visible to the public during business hours or when they are in an open position. (Ord. 1866, 11-19-2019)
