When conducting design review, the review authority shall evaluate applications to ensure that they satisfy the following criteria, conform to the policies of the general plan and any applicable specific or master plan, the Town's design guidelines, and are consistent with any other policies or guidelines the Town Council may adopt for this purpose. To obtain design review approval, projects must satisfy these criteria to the extent they apply.

(1)

The site design and building design elements, including the architectural style, size, design quality, use of building materials, and similar elements, combine together in an attractive and visually cohesive manner that is compatible with and complements the desired architectural or aesthetic character of the area and a mountain resort community, encourages increased pedestrian activity, and promotes compatibility among neighboring land uses.

(2)

The design of streetscapes, including street trees, lighting, and pedestrian furniture, is consistent with the character of commercial districts and nearby residential neighborhoods.

(3)

Parking areas are located, designed and developed to foster and implement the planned mobility system for the area; buffer surrounding land uses; minimize visibility; prevent conflicts between vehicles and pedestrians and cyclists; minimize stormwater runoff and the heat-island effect; and achieve a safe, efficient, and harmonious development.

Down-directed and shielded lighting and lighting fixtures are designed to complement buildings, be of appropriate scale, provide adequate light over walkways and parking areas to create a sense of pedestrian safety, minimize light pollution and trespass, and avoid creating glare.

(5)

Landscaping is designed to conserve water resources, promotes a natural aesthetic, and be compatible with and enhance the architectural character and features of the buildings on site, and help relate the building to the surrounding landscape.
