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

4. 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.

class A roof assembly or class A roof covering material, or structures with

ba. Additions: All additions affecting roof area shall trigger
compliance of the roof structure of a single-family dwelling, a side
of a two-family dwelling, or the entire multiple -family dwelling,
except for a onetime exemption of up to five hundred (500) square
feet of GRFA, occurring after February 6, 2007, where any addition
of roof area does not share a plane or ridge with the nonconforming
roof, and may only share a valley. 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.

designed in accordance with the minimum standards of the adopted
building code. Footings and foundations shall also be designed to be
responsive to the natural topography of the site, and shall be designed
and constructed in such a manner as to minimize the necessary amount of
excavation and site disturbance.
