Downtown buildings should be four-sided buildings and should be maintained from all sides.

The main entrance to the building shall front upon Main Street and should not be oriented towards the parking lot or rear of the site.

Secondary entries, such as side or rear entries, shall not be more architecturally prominent or larger than the front entry and shall be architecturally related to the front entry.

Heights of buildings in the main business district may vary but should be consistent with traditional building rhythm.

Horizontal mass. Buildings that exceed 30 feet in width along the public right-of-way create a horizontal monotonous rhythm. The following guidelines are suggested to create a visually interesting pattern:

Vertical mass. A vertical division in building facade is required to reduce the appearance of building height and bulk.

All one-story buildings must have a pitched roof. If a pitched roof is not possible, than a combination of a flat roof and pitched roof or a false roof structure is recommended.

Materials for pitched roofs shall be limited to architectural dimensional grade asphalt shingles, natural slate, natural terra cotta, natural wood shakes or copper.

All roof-mounted equipment shall be screened from public view by the use of a parapet wall or other architectural detail. Fencing shall not be utilized to screen rooftop equipment.

All buildings with flat roofs shall include a parapet articulation on the front facade of the building.

Exterior buildings' materials shall be classified as either primary, secondary or accent materials. Primary materials shall cover at least 60% of the facade of a building. Secondary materials shall cover no more than 30% of the facade. Accent materials may include door and window frames, lintels, cornices and other elements and may cover no more than 10% of the facade.

The combination of materials on a building's facade should be appropriate in style and design. If building mass and pattern of windows is complex, simple wall surfaces are recommended. If the building volume and the pattern of wall openings are simple, additional wall texture and articulation should be employed.

Elevations should incorporate change in materials and textures that define a building base, center and top to create a visual pattern. Side or rear elevations that do not face the public street but face a parking lot must incorporate change in texture or color to create interest in these areas and be compatible with overall building facade.

Primary materials should be chosen consistent with building style and type. These may include brick, stone or wood.

Color schemes shall be simple and coordinated over the entire building to establish a sense of overall composition. Color schemes must tie in together with signs, awnings, entrance, canopies and other ornamentation. Color shall be compatible with other buildings in the district.

Consistent with desired storefront character on Main Street, buildings shall maintain the desired transparency to maintain a visual interest for pedestrians as well as passers-by. The ground-floor street-facing elevations shall be comprised of a minimum of 60% of transparent windows or doors of the section facing the public street.

All entries shall be easily identifiable and accessible. If the main entrance is not handicapped accessible, a separate entrance shall be provided and clearly identified through signage.

All main entries should be provided with decorative trim and construction details matching the architecture of the remainder of the building facade.

All main entries shall incorporate glazing in the overall entry design to maximize visibility of the interior. Glass should occupy a minimum of 10% of the door. Glass can be used as noted below:

Storefront windows shall encompass a minimum of 60% of storefront facade area. Where greater privacy is desired for restaurants or small professional services, windows may be divided into smaller panes.

A minimum of 30% of the front facade or area between three feet and 10 feet in height along sidewalks, plazas, or public open space or rights-of-way should be window or door glass permitting a view of the building interior.

Display windows must be positioned within a maximum of three feet above the grade of the sidewalk and a maximum height of eight feet.

At the street level, there should be a maximum facade length without windows of 10 feet.

Bulkheads should have a maximum height of one foot and must utilize the same materials, colors and detailing as the display windows.

Upper facade windows should replicate the ground-floor window rhythm.

Windows on the upper facade may be smaller in size than storefront windows on the first floor and shall encompass a smaller proportion of the facade area.

The windows on the upper levels should have the appropriate sill or lintel to accent the openings and provide architectural interest.

Window sills and lintels should be provided on additions or renovations to match existing sills and lintels on all floors.

Air conditioner units should be concealed or disguised behind screens, grills, vents, or louver designs.

Windows should maintain consistency in shape and in location across the facade and be coordinated with facades of adjacent buildings.

Size, rhythm, location and quantity of windows that were originally installed should be preserved. (Improper replacements and window filling should be avoided.)
