7.28.090(d)(3)
(d) Generally Applicable Residential Design Standards:
(1) Applicability. The standards in this Section are applicable to the development of any residential
development pursuant to Section 7.28.010, Purpose and Applicability.
(2) Building Separation. The minimum separation between residential buildings, including accessory
buildings, is fifteen (15) feet. Architectural projections, such as decks, bay windows and roof
overhangs, may project into the separation area, but may not encroach into required setbacks.
(3) Roofs:
(i) All residential buildings shall have pitched roofs with a detectable. Primary roofs shall have
a four-to-twelve (4:12) minimum and a twelve-to-twelve (12:12) maximum. However, other
primary roof forms may be permitted if it is demonstrated that the proposed roof design has
implemented considerations of environmental and climatic determinants such as snow
shedding, drainage, fire safety and solar exposure.
Secondary roofs shall be pitched whenever practicable, consistent with the primary roof.
However, flat roofs may be permitted if the flat roof is consistent with the architectural style
of the building.
(ii) All buildings shall incorporate roofline modulation. 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.
7.28.090(j)(4)(ix)
(ix) Roofs. Roofs will serve to define scale. In addition to the general requirements of
Paragraph 7.28.090(c)(4), the following regulations shall apply to the roofs on mixed-use
and nonresidential structures:
(A) The use of dormers (shed, peaked, eyebrow, etc.) is required to help break up
large expanses of roof, to enhance the usability of attic spaces and to add visual
interest. Secondary dormers and roof elements shall be proportional to scale and
style.
(B) All primary roofs and secondary shed roofs be pitched for drainage purposes,
unless otherwise designed incorporating a drainage system.
(C) Overhangs are required on pitched roofs. The minimum overhang length
(measured from the point where the wall meets the roof) is eighteen (18) inches
for structures two (2) stories or less. For structures between three (3) and four (4)
stories the minimum overhang shall be twenty-four (24) inches. For structures
exceeding four (4) stories, the minimum overhang length shall be thirty-six (36)
inches for primary roofs.

(D) Flat roofs are discouraged, except for limited roof areas for the location of
concealed mechanical equipment or for architectural effect.
(E) Roofs shall be varied and articulated; however, valleys and complex roof forms are
a potential source of ice build-up and water damage and shall be used carefully
and sparingly.
(F) Roofs shall be proportional to the height and scale of the various building
elevations. The primary roofs and upper portion of the walls shall be articulated so
as to minimize their visual impact on surrounding properties, which may include
such measures as the introduction of decks and the lowering of rooflines.
(G) In the Town Center, unglazed concrete, copper, metal or terne-coated steel are
acceptable roof materials. Wood shake shingles are prohibited. Asphalt and
fiberglass are generally discouraged. Tile and metal roofs shall be a dull finish or
patina naturally over time and be muted to fit within the context of the overall
building design.
(H) All snowmelt systems must be in compliance with Building Code.
