Section 3. Section 14-10-5 of the Vail Town Code is hereby amended as follows: Sec. 14-10-5: Building Materials and Design. A. The Town is situated within the wildland urban interface where community values intersect with the potential consequences of wildland fires. Wildland fires both big and small have the potential to destroy homes and neighborhoods within the Town. The architecture and chosen materials of a building greatly affect the survivability of that structure in the face of a wildfire. The use of Class A roof coverings and ignition resistant building materials decrease the hazards to the individual structure as well as the surrounding homes. AB. The use of ignition resistant building materials and designs intended to prevent the spread of fire are highly encouraged. Vail Fire and Emergency Services is available to provide more information on the use of ignition resistant materials and designs. Predominantly natural building materials shall be used within the Town of Vail. The exterior use of wood, wood siding, native stone, brick, concrete, stucco, and EIFS may be permitted. Concrete surfaces, when permitted, shall be treated with texture and color; however, exposed aggregate is more acceptable than raw concrete. The exterior use of the following siding materials shall be prohibited: stucco or EIFS with gross textures or surface features that appear to imitate other materials, simulated stone, simulated brick, plastic and vinyl. The exterior use of any building material, including those not specifically identified by this section, shall only be permitted, unless otherwise prohibited by this code, where the design review board finds: 1. That the proposed material is satisfactory in general appearance, quality over time, architectural style, design, color, and texture; and 2. That the use of the proposed material complies with the intent of the provisions of this code; and 3. That the use of the proposed material is compatible with the structure, site, surrounding structures, and overall character of the Town of Vail; and 3 10/17/2016 C: IUSERSITNAGEL.

That the material is noncombustible or aids in the prevention of fires. BC. The same or similar building materials and colors shall be used on main structures and any accessory structures upon the site. GD. Exterior wall colors should be compatible with the site and surrounding buildings. Natural colors (earth tones found within the Vail area) should be utilized. Primary colors or other bright colors should be used only as accents and then sparingly such as upon trim or railings. All exterior wall materials must be continued down to finished grade thereby eliminating unfinished foundation walls. All exposed metal flashing, trim, flues, and rooftop mechanical equipment shall be anodized, painted or capable of weathering so as to be nonreflective. DE. The majority of roof forms within Vail are gable roofs with a pitch of at least four feet (4') in twelve feet (12'). However, other roof forms are allowed. Consideration of environmental and climatic determinants such as snow shedding, drainage, fire safety and solar exposure should be integral to the roof design. €F. Rooflines should be designed so as not to deposit snow on parking areas, trash storage areas, stairways, decks and balconies, or entryways. Secondary roofs, snow clips, and snow guards should be utilized to protect these areas from roof snow shedding if necessary. F.G. All structures shall have class A roof assemblies or shall have class A roof covering materials, as defined by the adopted building code. The use of concrete tile, slate, metal, asphalt shingle, fiberglass shingle, and built up tar and gravel roofing may be permitted. Metal roofing, when permitted, shall not reflect direct sunlight onto an adjacent property and shall be surfaced with a low gloss finish or be capable of weathering to a dull finish. Metal roofing, when permitted, shall be of a heavy gauge and designed to provide visual relief to the roof surface (including, but not limited to, a standing seam). Asphalt and fiberglass shingles, when permitted, shall - roofing square be designed to provide visual relief through texture, dimension and depth of appearance. The use of wood shake, wood shingles and rolled roofing shall not be permitted. Two-family and multi- family dwellings shall be required to have uniform roof covering materials, except when the design review board determines that the materials are compatible, are integral to the architectural style of the structure and different materials do not share any ridges or planes, but may share a valley. _ . . 1. Nonconforming Structures: All structures that do not have a class A roof assembly or class A roof covering material, or structures with 4 10/17/2016 C:IUSERSITNAGEL.

The additional roof area shall conform to roofing regulations, and shall be deemed compatible by the design review board. Gb. Two -Family Structures: Upon reroofing one side of a two- family dwelling, the other side may shall be required to be reroofed if the two (2) sides have roof systems that share ridges or planes. Different materials on each side of the two-family dwelling may be permitted by the design review board if the materials are deemed compatible, integral to the architectural style of the structure and share a valley or do not intersect. dc. Developments With Multiple Structures: Upon reroofing a single structure that is part of a multi -structure project with conforming roof covering materials that do not match existing materials, the conforming materials shall be deemed compatible with the existing nonconforming materials by the design review board. Upon reroofing of additional structures in the development, the materials shall match the approved conforming materials. Should the matching material no longer be manufactured, a different material may be permitted, should the materials be deemed compatible by the Design Review Board. GH. Rooftops: Rooftop heating and air conditioning equipment, large vent stacks, elevator penthouses and similar features should be avoided; however, if necessary, shall be designed to be compatible with the overall design of the structure or screened from view of all adjacent properties. 5 10/17/2016 C: I USERSITNAGEL.
