It is the intent of this article to use performance standards
for the regulation of industrial uses to facilitate a more objective
and equitable basis for control and to ensure that the community is
adequately protected from potential hazardous and nuisance-like effects.
A.
No operation or activity shall transmit any physical vibration that
is above the vibration perception threshold of an individual at or
beyond the property line of the source. Vibration perception threshold
means the minimum ground- or structure-borne vibrational motion necessary
to cause a normal person to be aware of the vibration by such direct
means as, but not limited to, sensation by touch or visual observation
of moving objects.
B.
Vibrations not directly under the control of the property user and
vibrations from temporary construction or maintenance activities shall
be exempt from the above standard.
No operation or activity shall produce any intense glare or
lighting with the source directly visible beyond an industrial district's
boundaries or register 1/2 footcandle at a residential property line.
No operation or activity shall emit any substance or combination
of substances in such quantities that create an objectionable odor
as defined in § NR 429.03, Wis. Adm. Code.
No operation or activity shall emit into the ambient air from
any direct or portable source any matter that will affect visibility
in excess of the limitations established in Ch. NR 415, Wis. Adm.
Code
No operation or activity shall emit into the ambient air from
any direct or portable source any matter that will affect visibility
in excess of the limitations established in Ch. NR 431, Wis. Adm.
Code.
No operation or activity shall emit any hazardous substances
in such a quantity, concentration or duration as to be injurious to
human health or property, and all emissions of hazardous substances
shall not exceed the limitations established in Ch. NR 445, Wis. Adm.
Code.
A.
Purpose. The purpose of this section is to serve the public interest
by requiring the design of new buildings and changes of existing building
to meet minimum architectural design standards to minimize adverse
impacts on adjacent properties.
B.
Unless otherwise noted, all properties in the Multifamily, Commercial
and Industrial Districts shall comply with the standards of this section.
(1)
These provisions apply to all new buildings and additions to existing
buildings where the addition exceeds a 50% expansion of the existing
building footprint.
C.
The applicant shall provide documentation (scaled drawings, sketches,
color renderings, narrative descriptions, etc.) as to how the following
standards apply:
(1)
Context refers to how the proposal fits with the surrounding area.
New design elements should be compatible with nearby development.
(a)
A building addition should match or complement the existing
structure.
(2)
Scale is the relative size and mass of structures compared to one
another.
(a)
A small building should not be constructed adjacent to large
buildings unless provisions are made to minimize the difference in
scale. Refer to Figure 1.
(b)
The visual continuity of roofs and contributing elements (parapet
walls, cornices, etc.) should be maintained in building development
or redevelopment.
|
Figure 1: Streetwall
To create a visually unified "streetwall," new buildings shall
be no more than 30 feet taller or 30 feet shorter than the height
of the existing building(s).
 |
(3)
Balance and proportion are the relationship of one building to another
where each is in harmony with their surroundings.
(a)
The vertical pattern of exterior building elements should be
compatible in design and elevation of existing buildings in the immediate
area.
(b)
The horizontal pattern of exterior building elements formed
by patterns of windows and doors should be spaced at regular intervals
across all visible facades of the building and should be compatible
with existing buildings in the immediate area.
(c)
Unless otherwise exempted by the Zoning Administrator or Plan
Commission, the applicant shall submit with the application a minimum
of one color rendering of the proposal.
(4)
Unity and theme pertain to a consistent style and purpose, especially
applicable to a multiple building development.
(5)
Color and material elements apply to a building exterior that is
generally visible from a public street and/or alley.
(a)
Building color should be nonreflective and high-intensity, fluorescent,
day glow and/or neon and metallic colors are discouraged; where such
colors constitute a component of a standardized corporate theme or
identity, muted versions colors, with Plan Commission approval, may
be used.
[1]
Structures in the Commercial District designated as historic
buildings shall be either earth-tone colored or colored appropriate
to the period in history for which they were designated.
(b)
Primary exterior building materials should be similar and/or
complementary to existing structures within the immediate area. Building
materials should consider the facades of the structure and an adjoining
structure to provide a suitable transition between facades. Where
a side and/or rear elevation is not exposed to view from a public
street, a combination of primary and secondary materials may be used.
(c)
Secondary materials should be similar in color, shape, and appearance
to the primary materials but the aesthetic and/or finished qualities
of the primary materials are not required.
(d)
Acceptable surface materials include but are not limited to,
glass, brick, ceramic tile, terra cotta, cultured stone, cut stone,
carved stone, stucco, wood, decorative concrete block, metal roofs,
decorative metal, and metal accent components.
[1]
Stone or brick facing shall be of relatively even coloration
and consistent in size.
(e)
The use of nondecorative exposed concrete block, preengineered
metal building systems, and sheet may be used with Plan Commission
approval.
(f)
The use of plywood or oriented strand board (OSB) or similar
materials is prohibited.
(g)
The Zoning Administrator may permit exterior surface materials
not listed in the subsection, provided the material is a result of
new technology and/or the material is equal to better quality, appearance,
and durability than the permitted materials. The applicant shall provide
the manufacturer's warranty of any nonlisted materials.
(6)
In Commercial Zones, the traditional storefront design theme, characterized
by strong horizontal and vertical rhythms formed by building openings,
columns, cornices, kick plates, sign bands, large display windows
and transom windows, shall be employed, when practical.
(a)
Building facades should not be cluttered with brackets, wiring,
meter boxes, antennas, gutters, downspouts, and other appurtenances.
Appurtenances shall be colored to blend with the building exterior.
Ornamentation that is inconsistent with the general design theme of
the downtown area may be prohibited.
(b)
Clear or slightly tinted glass should be used. Mirror glass,
smoked glass or heavily tinted glass is not permitted.
(7)
Building length and facades. Buildings greater than 100 feet in length
shall be divided into smaller increments of between 45 feet and 85
feet through articulation of the facade. This can be achieved through
combinations of the following techniques or, with Plan Commission
approval, other similar techniques:
(a)
Stepping back or extending forward a portion of the facade.
(b)
Using different textures or materials. The materials shall be
drawn from a common palette.
(c)
Dividing facades, with separate display windows and entrances.
(d)
Varying the rooflines by alternating dormers, stepped roofs,
gables or other roof elements.
(8)
All metering and mechanicals, such as but not limited to transformers,
gas and electric meters, rooftop units, utility service boxes, cables,
conduits, vents, turbines, flues, chillers and fans, telecommunication
devices, and trash/recycling storage receptacles shall be screened
from public view, except when state statutes or other regulations
require otherwise, by incorporating the following design standards:
(a)
Locate mechanical equipment and service areas at the rear of
the building along an alley facade or on the building rooftop.
(b)
Screen mechanical equipment and service areas, as per L-6 of the Landscape Standards in Article XIII.
(c)
Mechanical equipment located on a building rooftop shall be
set back from the building edge a sufficient distance to screen the
equipment from view of adjacent streets.
