Root Treatment 1. The style of the roof should be in accordance with the building's architectural character to enhance the value of the building design. 2. A variety of roof planes and ridge heights may be used. 3. Rooftop and other building mechanical equipment should be screened from public view. z The building mechanical equipment should be housed within the building of enclosed in a penthouse structure that is incorporated with the design of the building. • When mechanical equipment is placed on a rooftop, it should be located below the highest vertical element of the building wherever possible to avoid the use of penthouse structures or other special screening devices. • When mechanical equipment is added to an existing building, it should be screened in such a way as m match the architectural style and materials of the existing building without giving the appearance of being added on. • Mechanical equipment should be placed away from adjacent residential uses to minimize noise impacts. 4. Roof drains should be designed as an integral part of the structure. 5. Roof access should be provided from the interior of the building. Exterior roof access ladders are not appropriate. Building Colors and Materials 1. Buildings shall use durable, high quality materials to develop long - lasting buildings which can be adaptively reused over time. • Brick, natural stone, precast concrete, and factory - finished metal panels (heavy gauge only, in corrugated or flat sections) are preferred • Altematives to stucco are preferred. When sucm is used it should be applied with a smooth finish. Stu= seams should be used to create visual interest for the buildings facade and form. • The finish, texture, and color of materials should be compadble with the overall architectural theme. 2. Greater anentlon m detail and quality should be used at the lower levels of a building to contribute to an enhanced streetsrape. 3. Encourage buildings to express a variety of architectural styles, butwith full awareness of, and respect for, the height, mass, articulation, and materials of the high quality (desirable) older buildings that surround them. 4. Architectural style and use of quality materials shall be consistent throughout an entire mixecli project; however, variations in materials and details may be used to differentiate between the residential and commercial portions of the project. 5. Construction details should be authentic and applied with consistency. Faux architecture that mimics a past era is strongly discouraged. 6. Materials and colors should be used to imply form changes, particularly for entrance lobbies, massing changes, and different uses or tenants. 7. Bright color palettes should be tested onsite to verify appropriateness for the site and block. 8. Garage openings, entrance canopies, scuppers, downspouts, and metal railings should follow the aesthetic of the building theme. 9. The use of concrete is allowed as long as it is part of an overall architectural composition, and it should have a finished architectural expression. 10.Facade elements constructed of foam or foam molding is prohibited on the ground floor of buildings and should be avoided overall. if used, they should be well proportioned and constructed to avoid appearing glued to the building. 11. Concrete masonry units should only be used if they are fundamental to the building design and have a suitable appearance at the ground floor. Windows, Boors, Balconies, and Walls 1. The rhythm of windows and entrances should provide interest and engage pedestrians. 2. Clear One should be used on the ground ficor of facades with marginal obstruction from window signs, permanent shades, or interior displays. 3. Balconies and bay windows in upper stones are encouraged to enhance activity and provide "eyes on the street" 4. The design, size, type, and location of windows should enhance interior daylight and potentially decrease the sizeltype of required heading/cooling systems. 5. For nonresidential storefronts, curtain wall, metal panel, frameless glass porch wall systems, and high quality glass storefront wall systems should be used. a) Installation using a vertical cavity system and reinforced fiber cement panels are acceptable. b) Windows and glass curtain wall systems should be transparent.
