. Design and Development Guidelines/Covenants:
City of Muskego
Purpose of the Guidelines
The City of Muskego recognizes the importance of quality design in preserving the community's
distinctive natural setting and high quality of life; in promoting sustainable design practices; and in
maintaining competitiveness within area real estate markets. The purpose of the Business Park
Design and Development Standards is to assure quality site planning and building design that unifies
the natural and built features of the community; conforms to local building traditions and tastes;
minimizes environmental impacts; and establishes benchmarks for future design. The standards
place particular emphasis on preserving and accenting the many landfonns and other natural
features that contribute to the community's rural imagery.
The standards are presented more a series of 'best practices' than measurable standards; therefore,
the applicability of guidelines will require interpretation on a case-by-case basis. Precise standards for
such things as building height, Jot dimensions, lot coverage, floor area ratio, and other measurable
standards are found in the City Zoning Ordinance and are herein incorporated by reference. Any
inconsistencies between the standards set forth in these guidelines, and the City's zoning or
subdivision ordinance shall be superceded by the latter. Exemptions from certain of the standards
may be appropriate where the spirit and intent of the guidelines can be effectively achieved through
alternative means.
.
. Environmental Conservation & Other Eco-Friendly Design Practices
The City of Muskego strongly encourages environmental consef\"ation and other sustainable design
practices in all new projects. Such practices as: sod roofs to both minimize stormwater runoff and to
reduce heat gain; berming and coving of structures to achieve geo-thermal efficiencies and visual
screening (provided that existing landforms aren't radically altered); sensitive siting and orientation
of structures to take advantage of natural light, solar heat and power, and to provide heat and wind
protection; are encouraged. The City may permit slight deviations from those standards that are
purely aesthetic in nature, to accommodate such measures.
Sustainable environmental techniques that are encouraged or
required may include the following:
. Stormwater retention ponds
Infiltration and bio-infiltration swales
Pervious low use parking areas and parking lot islands
Reductions in paved surfaces to reduce runoff
Rooftop stormwater infiltraciðri
Vegetated s.tream buffers
Energy efficient building materials
Alternative/ renewable 'clean' energy use
Alternative transportation access

Strategic Economic Development Plan Appendix A: Design Standards
Site Layout & Lot Coverage
Site design should be responsive to adjacent buildings and landforms. Development shall be fitted to
the natural landscape and adhere to least illvasive development practices. Existing natural features
such as ridges, slopes, tree lines, and viewsheds should be protected and serve as the major
organizing elements of the design plan. Site prep work such as grading, excavation, filling, and
contouring should be minimized to the extent possible and all unnecessary disturbance to existing
vegetation and wooded areas should be avoided. Special care shall be given to relating proposed
buildings to other structures, both existing and planned. Special attention shall be given to
preserving large areas of open space, and assembling smaller fragments of open space into larger
natural corridors and preserves. Every effort should be made to reduce viewshed encroachment and
stormwater runoff. Energy conservation measures, as well as alternative energy and transportation
use will be given special consideration in plan review. Building footprints, parking areas, and other
hardscape features should cover no more than 60% of any deyelopment site per the zoning
ordinance. In addition, land disturbance shall not extend beyond 75' from the perimeter of all
buildings. All sites should provide pedestrian and bicycle access to adjacent public rights-of-way. All
on-site access roads shall be separated from parking areas by a raised walkway, planting area or
combinarion thereof.

City of Muskego Working Draft: June 18, 2003 A-7
Strategic Economic Development Plan Appendix A: Design Standards
. Building arrangement, orientation, and massing
Individual structures within the business park should not be designed or sited in isolation, but rather
as part of distinct building groups that exhibit a general similarity of scale, orientation ànd
proportion. All visible building elevations (sides), especially those with direct street frontage, should
be embellished with multiple windows, clearly marked entrances, and variations (protrusions and
recessions) in the façade surface, strongly defined roof lines and window/door openings,
landscaping, and the use of multiple building materials. Rectangular, "horizontal, and asymmetrical
building shapes are generally favored over vertical structures, rounded building shapes, and those
that exhibit a regularity or lack of differentiation in form, materials, and details.
~
Building heights shall not exceed the limitations set forth in the zoning ordinance. As a general rule,
taller structures shall be placed toward the interior of the site, and stepped back from the street.
The City encourages the use of shared parking and outdoor recreational areas, and special
consideration will be afforded plans that attempt to accommodate them. Buildings that attempt to
utilize solar heat/power, distributed energy, and/or co-generation will also be given special
allowances as to building orientation, surface materials, and appurtenances. \X1herever possible,
buildings should be grouped or sited \vith other buildings and landscape features to create distinct
outdoor spaces. Special care will be given to the protection of \;ews and solar access. No building
should exceed the square footage limitations or floor area ratio requirements prescribed in the
Zoning Ordinance. Building setbacks should also adhere to those prescribed in the zoning
ordinance.

City of Muskego A-9 Working Draft June 18, 2003
Strategic Economic Development Plan Appendix A: Design Standards
Entryway and View-Tenninating Sites
Buildings and sites with the greatest overall visibility will be held to the highest standards of design.
Such buildings would include those near the entrances of the Business Park (1.e. monument
buildings), structures that close views within the park (generally those that are directionally on-line
with streets and view corridors); comer buildings; building that occupy points of prospect within the
park; and those that encroach upon a viewshed as identified in the Cf!Y ofMuskego Conservation Plan.
Special care must be taken to either camouflage or accent the most visually prominent surfaces of
these buildings depending upon the nature of the exposed activity and whether thç site lines are
internal to the business park or extend beyond its boundaries. For example, front facades that are
visually prominent within or just outside the park (e.g. entryway buildings, comer buildings, and
those that close views within the park), should be accentuated through architectural treatments,
lighting, and landscaping, while aI/building surfaces that are potentially seen from outside the park
should be camouflaged to the extent practicable. The fronts of buildings will generally require less
screening than the sides and backs of buildings. In general, building fronts should be exposed to
view and highlighted except where visible from outside the park. In all cases, loading, storage, and
parking areas should be kept away from the most visible portions of the site, and otherwise screened
from view.

Strategic Economic Development Plan Appendix A: Design Standards
Architecture
Buildings should express the structure's main use but avoid the outward appearance of spartan Or
. utilitarian design. All sides of buildings should be designed with a similar attention to detail.
Francruse arcrutecture shall be subdued and be relational in scale, roolline, color, and form to nearby
buildings. Strip centers and buildings consisting predominantJy of prefabricated components are
discouraged.
Simple shapes that reflect the nature and variety of interior functions are prefened. Front offices of
buildings designed primarily for light manufacturing, assembly, or warehousing should be clearly
expressed on the exterior through changes of materials, surface texture, color, window dimensions
Or through protrusions/recessions in the façade surface. Building bases and roollines should be
strongly defined and contrasted f~om other façade elements. The massing of large structures should
be broken down into smaller volumes and divided by piers, bays, banks of windows, and changes in
roof shape Or roof-line. Major structural components such as piers, bays, and roof trusses may be
used as exterior design elements. All visible sides of a building including all office, plant, and
warehouse enclosures, should eilibit a unified arcrutectural tteatmenr. Long blank walls, unrelieved
with window/door openings, structural bays, changes of materials, texture and other variations in
the façade surface are discouraged along with 'curtain wall' office construction. \X'here windows on
side/rear elevations are not practical for security of other reasons, clearstory windows should be
used to provide interior light and exterior decoration.
Special consideration will be given to developments that utilize solar, distributed energy, and co-
generation (combined heat and power) and other sustainable design/alterative energy techniques.
Buildings in the business park should not exceed the height and floor area limitations set forth in the
Zoning Ordinance.
. Building Materials
Exterior surfaces may include brick,
stone, wood, concrete, glass or
decorative architectural metals.
Examples include face brick, smooth or
textured precast or poured concrete
panels; cut stone; textured and/or
colored metal panels and ttim; and clear
or lighdy tinted glass. Arcrutectural
block, wood siding, reflective glass,
corrugated metal panels, and synthetic
materials, are prorubited. The front and
side-walls of all structures facing a stteet
should consist mosdy of decorative
masonry or other decorative mat~ , ,

Landscaping
Site plans should confonn to the natural landscape and incorporate existing landscape features. The
landscape plan should also seek to unify adjacent building sites and public areas, and screen side or
'back-lot' activities such as parking, loading, service and storage. Special care should also be taken to
create attractive transitions between the 'built' and natural landscape features of the site and adjacent
sites. Visually prominent sites such as park entrances, fixed-view sites, and street comers should be
given special emphasis in both building and landscape design Landscaping should exmbit organic
and infonnal qualities rather than appearing oyerly manicured, formal, or ornamental. Groups of
trees and understory shrubs should be used to frame major façade elements such as entrances, banks
of windows, and pedestrian areas; or to screen blank walls, parking and loading areas, and storage
yards. A mix of hearty, indigenous landscape materials that provide variation in height, color,
texture, density, and drought/disease resistance, should be used.
The landscape plan should strive to capture as much stonnwater runoff on-site as possible. Rain
gardens, sod roofs, and inf1lrration basins are encouraged for tms purpose. Retention ponds should
offer amenity value and appear irregular and organic in shape. Berms maT be used to screen parking
and loading areas, and to provide visual separation between the natural and built elements of the
park provided that they exJùbit a natural profile and contour. All setbacks and planting strips should
adhere to the standards set forth in the City's zoning ordinance. Trees shall be required at a ratio of
no less than one per each 500 square feet of landscape area along the building perimeter.
Landscaping is also required witlùn parking areas and along parking lot perimeters (see Parking
below).
All landscape plans and planting materials shall be reviewed and approved by the City Forester.

Signs
All signs should be ground or wall mounted. Internally lit signs should be constructed of high
quality, durable materials with a low degree of transparency and radiance. They should compliment
the architecture of the building through a related sense of proportion, detail, color, and use of
materials. \Vall signs will not be permitted to extend beyond the roolline. Roof mounted signs, pole
signs, and all forms of product advertising are not permitted. Window sigos consisting of etched
lettering on glass may be permitted at the main entrance to the building in addition to the main sign.
Temporary sigos, not to include movable letter boards, may be permitted on a temporary basis with
the approval of the Planning Commission Sign content may include the name anctlogo of the
enterprise only.
All directional and parking control signs should be unobtrusive and consistent in format. Sign
content should be restricted to the minimum necessary to communicate essential information.
.
Utilities
All utilities shall be located underground. All visible building appurtenances, including roof-mounted
equipment should be screened from view. Such equipment includes anything associated with power
generation and transmission or HV AC units. Rooftop equipment should be screened with parapet
walls or individual shelters. Ground mounted equipment should be screened either with dense
landscaping, opaque fencing, or walls and shelters that complement the architecture of the building.
Rooftop solar devices are exempt from this requirement except where they may result in excessive
glare or the obstruction of views.
All rooftop radio, TV, cellular, and microwave towers and antennas should comply with the stealth
requirements of the City's \VireJess Facilities Ordinance. .
Lighting
Exterior lighting should be subdued to avoid light penetration to surrounding neighborhoods, and
to preserve Muskego's night sky. Lighted areas should be limited to primary building access points
only. Except for minor accent lighting near major entrances and prominent architectural features,
buildings should be darkened in the evenings to avoid 'glowing'. All exterior lighting, including the
lighting of signs, shall consist of indirect or hidden light sources. Only cutoff light fIxtures should be
used to avoid light spillage. Wall mounted security lighting may be used only in service areas where
direct light and glare is contained \vithin the service area. Exterior lighting should consist of high-
pressure sodium lights only.
Parking
The City discourages large, oversized parking lots, and encourages the
shared use of parking facilities wherever possible. Expansive parking
Jots along the street-front are especially discouraged. It is
recommended that parking areas"qe broken up into smaller pads and
segregated by use (i.e. employee or visitor). Visitor parking should be
confJgUred on small Jots and located near the front or sides of
buildings. Larger employee and service Jots should be located toward
the rear of buildings and screened from view. All parking areas,
including employee parking, should feature landscaping along the
perimeter and on planting islands arranged within the Jots. (A general
rule of thumb is one tree island for each linear row of ten parking
spaces.) The extent oflandscaping should be in proportion to the

visibility of the lot from nearby streets, buildings, and natural areas. Generally visitor lots shoùld
receive the greatest amount of design treatment due to their greater visibility and use. Tree islands
. should comply with the dimensional requirements of the zoning ordinance and be planted with
canopy trees for shade and vertical dimension. All parking surfaces shall consist of durable, all
weather materials.
Loading Areas
Loading and service areas shall be located on the sides of buildings least open to view from public
rights-of-way, adjacent buildings, and view corridors. These areas shall be further screened by dense
landscaping and by walls and opaque fences that complement the architecture of the building.
Storage Areas
All storage areas shall be indoors and fully enclosed. Freestanding storage strUctures shall mimic the
design of the main strUcture and observe all architectural guidelines described above. Outdoor
storage of materials and equipment is prohibited.
All trash receptacles shall be placed to the rear of the site and screened by masonry walls. Opaque
fencing may be used for gates only. All enclosures should match the color and materials of the
primary building-
