MEMORANDUM
March 22, 2007
TO: Zoning Advisory Commission
FROM: Laura Carstens, Planning Services Manager
SUBJECT: Interim Design Standards for-Big Box Retail Uses
Introduction
This memorandum transmits a text amendment to the PUD Planned Unit Development
District section and the Definitions section of the Zoning Ordinance for big box retailers.
Background
The City has hired JEO Consulting to assist with updating the Zoning and Subdivision
Ordinances, and then combining them with the Historic Preservation Ordinance and City
sign regulations into a Unified Development Code (UDC).
As part of the process for creating the UDC, the City Council asked JEO to evaluate
design standards for big box retailers, and any impact studies or impact fees that have
been implemented as a result of the location of a big box retailer. While this evaluation
is underway, we have developed interim design standards for big box retail uses.
These proposed regulations were developed with input from GDDC and Economic
Development Department staff. They also have been reviewed with the UDC Citizen
Advisory Committee.
These interim design standards are based on the standards established for the River
View Plaza development agreement for redevelopment of the former Smithfield meat
packing site, and the Port of Dubuque Design Standards. The final version will include
more defini#ions, more detailed standards, and illustrations.
Discussion
Presently, PUD zoning is required for any department store over 60,000 square feet in
size and for regional shopping centers. This requirement applies to expansions of
existing retailers that expand to over 60,000 square feet and by at least 25%.
Interim Design Standards for Big Box Retail Uses
Page 2
Definition
Planning Services staff have interpreted "department store" to include a variety of retail
and wholesale/warehouse club operations. Staff is recommending that department store
be replaced with retail commercial uses. The proposed definition for retail commercial
uses is a stand-alone building with a large parking lot or a part of a larger commercial
center, including but not limited to: department store, grocery store, supermarket,
wholesale club operation, discount store, general merchandise retailer, specialized
product store (for example, electronics, building materials or pet supplies), outlet store,
general merchandise wholesaler open to the public, warehouse club, and similar uses.
Special Conditions for Retail Commercial Uses and Regional Shopping Centers
Staff is recommending special conditions that would apply to all retail commercial uses
over 60,000 square feet in size and regional shopping centers.
(a) Sales and display areas other than the front facade require a temporary use permit
has been obtained from the City of Dubuque.
(b) Sidewalks, walkways, entrances and gathering areas. Sidewalks adjacent to the
front facade must be at least 10 feet wide and connect by 5-foot sidewalks to public
sidewalks and adjoining retail buildings. Walkways, entrances, and gathering areas
are to have shade features other than landscaping, such as trellis structures,
projecting canopies, covered arcades and porticos.
(c) Transit facilities. The City Manager can approve a bus and paratransit stop/transfer
point adjacent to the building, with a shelter design that is consistent with the
building. The shelter would be installed at the property owner's expense. An
easement or other arrangement acceptable to the City must be granted for location,
maintenance, and unrestricted use of these transit facilities by the City transit
system.
(d) Bicycle paths and parking. The building site must include bicycle paths connected to
the City's planned and existing bike trail system. Flexibility in the timing of
construction of these bicycle paths may be allowed at the sole discretion of the City
Manager. Unless the paths are exclusively for bicycle use, they shall be
appropriately marked with painted lanes. The building site must include sheltered
bicycle areas with rack(s) for securing bicycles located near the entrance to the
building.
Design Standards for "Big Box" Retail Uses
Any retail commercial uses or regional shopping centers which have over 100,000
square feet of building area, or expand to over 100,000 square feet and by at least 25%,
must also meet big box design standards.
a) Definitions of facades. The proposal defines the front, side and rear facades of a
building.
Interim Design Standards for Big Box Retail Uses
Page 3
b) Facades. The building facades are to be designed to reduce the massive scale
and minimize a uniform and impersonal appearance of the building, and to
provide visual interest consistent with the community's identity, character, and
scale. This can be done with projections and recessions, windows, arcades,
awnings, projecting canopies, covered walkways, porticos, or other acceptable
features. The facade to give the visual exterior appearance of having more than
one floor. A landscape buffer of evergreens is required along the property line to
screen service areas and rear facades from the adjacent property.
c) Detail features. The building must include architectural features that contribute to
visual interest at the pedestrian scale and reduce the massive aesthetic effect by
breaking up the building wall, front, and side, with color, texture change, wall
offsets, reveals, or projecting ribs.
d) Roofs. The roof design must provide variations in rooflines, add interest to, and
reduce the massive scale of, large buildings. Roofs shall include two (2) or more
roof planes. Parapet walls shall be architecturally treated to avoid a plain,
monotonous look. The roof design also must provide for a green roof, which is at
least 50% covered with vegetation and soil, or a growing medium, planted over a
waterproofing membrane.
e) Materials and color. The buildings must have exterior building materials and
colors that are aesthetically pleasing and compatible with materials and colors
that are used in adjoining neighborhoods. This includes the use of high-quality
materials and colors that are low reflective, subtle, neutral, or earth tone. Certain
types of colors are to be avoided such as fluorescent or metallic although brighter
colors in limited quantities may be used on building trim and as accents at the
discretion of the City Council. Construction materials such as tilt-up concrete,
smooth-faced concrete block, prefabricated steel panels, and other similar
materials are to be avoided unless the exterior surface incorporates an
acceptable architectural treatment. Not less than 75% of the front of the building
and 50% of the sides of the building must be brick or stone.
f) Entryways. Entrances must be highly-visible to customers and add aesthetically
pleasing character to buildings.
g) Screening of mechanical equipment. Mechanical equipment must be screened to
mitigate noise and views in all directions. If roof-mounted, the screen must be
designed to conform architecturally to the design of the building either with
varying roof planes or with parapet walls.
h) Parking lots. Parking lot requirements are the same as those found in the Port of
Dubuque Design Standards.
i) Employee parking. Employee parking must be behind the building.
Interim Design Standards for Big Box Retail Uses
Page 4
j) Amenities. The building site must include at least one public gathering space,
such as a patio seating area, pedestrian plaza with benches, outdoor play area,
and not less than two public space amenities, such as kiosks, a water feature, a
clock tower, or a landscaped site for public artwork. Pedestrian public space
must be shaded, landscaped, and screened. The size of the public gathering
space shall not be less than 1 % of the gross enclosed building area.
Flexibility
The proposal includes a provision for flexibility: In determining whether the plan
complies with the above standards, the City Council may accept alternative or substitute
features which have a comparable aesthetic and visual effect in light of the location and
topography of a particular site.
Recommendation
Staff recommends that the Zoning Advisory Commission recommend approval of the
interim design standards for big box retail uses.
The Zoning Advisory Commission will have an opportunity to review final design
standards for big box retailers later in the UDC process.

area and which expansion constitutes an increase of twenty five percent (25%) or more
to the building area shall be subject to these Design Standards.
The applicant shall not commence any such construction unless the City Council
determines that the plan complies with the following standards for aesthetic and visual
characteristics:
a) Definitions of facades. For purposes of this section, the facades of a building
shall be defined as follows:

massive scale and minimize a uniform and impersonal appearance of the
building, and that will provide visual interest consistent with the community's
identity, character, and scale.
Facades of one hundred (100) feet or longer shall be broken up with projections
or recessions not less than five (5) feet in depth, and in sufficient number, to
reduce the unbroken massing into lengths of forty (40) feet or less along all sides
of the building. Projections from the facade can be used as an alternate
approach.
The front facade shall include windows, arcades, awnings, projecting canopies,
covered walkways, porticos, or other acceptable features along at least sixty
percent (60%) of the front facade length and over at least twenty five percent
(25%) of the front facade area.

eleven (11) feet shall give the visual exterior appearance of having more than
one floor for each additional eleven (11) feet in height, i.e., a twenty-two (22) foot
high building shall give the appearance of a two-story building.
Arcades and other weather protection features shall be of sufficient depth and
height to provide a light-filled and open space along the front facade.
Architectural treatment, similar to that provided to the front facade, shall be
provided to the side facades to mitigate any nega#ive view from any location off-
site and any public area (e.g. parking lots, walkways, etc.) on site.
A landscape buffer of evergreens approved by the City Council shall be required
along the property line to screen service areas and rear facades from the
adjacent property.
c) Detail features. The building shall include architectural features that contribute to
visual interest at the pedestrian scale and reduce the massive aesthetic effect by

soil, or a growing medium, planted over a waterproofing membrane. It may also
include additional layers such as a root barrier and drainage and irrigation
systems.
Unhealthy or dead vegetation shall be removed within seven (7) days and
replaced with suitable new plant materials at the earliest practical time, but not
longer than nine (9) months, based on the appropriate season.
e) Materials and color. The building shall have exterior building materials and colors
that are "aesthetically pleasing and compatible with materials and colors that are
used in adjoining neighborhoods. This includes the use of high-quality materials

limited quantities may be used on building trim and as accents at the discretion of
the City Council. Construction materials such as tilt-up concrete, smooth-faced
concrete block, prefabricated steel panels, and other similar materials shall be
avoided unless the exterior surface incorporates an acceptable architectural
treatment. Not less than seventy-five percent (75%) of the front of the building
and fifty percent (50%) of the sides of the building shall be brick or stone.
f) Entryways. The building design shall provide design elements which clearly
indicate to customers where the entrances are located and which add
aesthetically pleasing character to buildings by providing highly-visible customer
entrances.
g) Screening of mechanical equipment. Mechanical equipment shall be screened to
mitigate noise and views in all directions. If roof-mounted, the screen shall be
designed to conform architecturally to the design of the building either with
varying roof planes or with parapet walls. A wood fence or similar treatment is not
acceptable.
h) Parking lots. Parking lots fronting on public streets shall be set back 12 feet from
the right-of--way and eight {8) feet from internal drives measured from the edge of
the paving. A landscaped buffer strip at least twelve (12) feet wide shall be
provided between all surface parking areas and the sidewalk or street. The buffer
strip shall consist of landscaped earth berms, shade trees, low shrubs and/or
perennial flowers (3 feet in height maximum), and a decorative metal fence no
more than 4 feet high supported between decorative masonry columns. Use of
biofiltration methods of landscape and drainage is encouraged.
A landscape buffer at least twelve (12) feet wide shall be provided along the rear
