The purpose of this article is to establish landscaping requirements
and other regulations intended to preserve and maintain vegetation
within in a manner that promotes the natural resource protection,
aesthetic, and public health goals of the City.
A.
The requirements of this section shall not apply retroactively to
existing buildings, structures, or paved areas, including requirements
for bufferyards.
B.
Any use for which site plan approval is required under § 300-10.43 shall provide landscaping in accordance with the regulations of this section, including the following development:
(1)
New buildings and paved areas.
(2)
Expansions.
(a)
Expansions of existing buildings that exceed 50% of the existing
floor area of the building.
(b)
Expansions of paved areas that exceed 50% of the existing paved
area.
(c)
In the case of expansions, only the new portion of building
or paved area shall provide landscaping per the requirements of this
article.
C.
Where insufficient site area remains to comply with all provisions
of this section, the City may require compliance to the greatest extent
practical.
D.
This article is designed to encourage preservation of existing plants on the site by granting them double point values per § 300-8.30G(1).
E.
Exemptions.
(1)
Single-family dwelling units, two family dwelling units, and agricultural land uses are exempt from landscaping requirements. See § 300-6.06I for screening requirements for uncovered parking spaces associated with single-family and two family uses.
(2)
All uses in the Downtown Historic Mixed-Use District are exempt
from landscaping requirements for building frontages, street frontages,
and yards, but must meet the landscaping requirements for paved areas.
F.
Changes to the landscaping plan. The City may allow or require changes to the landscaping plan of § 300-8.20 or the landscaping requirements of § 300-8.36, as provided for below.
(1)
The Building/Zoning Inspector, and the Plan Commission shall
have the authority to allow alterations or substitutions of one type
of plant for another to the landscaping requirements as long as the
altered requirements achieve an equivalent or greater level of landscaping
on a site. Such alternations or substitutions may be based on the
following:
(a)
Unusual conditions.
(b)
The consideration of landscape architecture approaches.
(c)
The preservation of existing trees.
(d)
The consideration of Wisconsin native landscaping.
(e)
When larger size plantings are provided as part of the overall
landscape plan.
(f)
When more shrubs may be appropriate versus more trees, and vice
versa.
(g)
Utility or other easements.
(2)
The Building/Zoning Inspector, and the Plan Commission shall
have the authority to require the modification of any landscaping
plan including the rearrangement of landscaping points on a site to
better meet aesthetic, environmental, and stormwater goal or objectives.
The applicant shall provide a digital copy of a landscaping
plan. The plan shall be drawn at a reasonable scale to clearly delineate
the landscape improvements and depict the following, at the discretion
of the Building/Zoning Inspector:
A.
The name and address of the developer/owner, architect/designer name,
date of plan preparation, date and description of all revisions, name
of project or development, scale of plan, and north point indication.
B.
All property lines and easements.
C.
Zoning of the subject property and abutting properties.
D.
The location and dimensions of all existing and proposed structures,
parking lots, driveways, roads, underground utilities, right-of-way,
sidewalks, ground signs, refuse disposal areas, fences, freestanding
electrical equipment and other utility boxes, and other freestanding
structural features as determined necessary by the Building/Zoning
Inspector.
E.
The location and contours at two-foot intervals, of all proposed
berms.
F.
The location, size, and type (common and botanical) of all existing
plant material on the site and designation of all trees and shrubs
to be saved and/or removed.
G.
The location, quantity, size at planting, and type (common and botanical)
of all proposed plant material. All plants shall be drawn at the spread
they will achieve at maturity.
H.
The number of landscaping points per Figure 300-8.30d for all plant
material.
I.
Details of refuse disposal area screening and mechanical equipment
and utility screening.
J.
Linear feet of the new/expanded building foundation and street frontage.
K.
Square footage of the total lot and new/expanded paved area.
Landscaping shall be provided based on the following requirements
for building foundations, paved areas, street frontages, yards, and
bufferyards.
A.
Building foundations.
(1)
For every 100 linear feet of building foundation, the landscaping
installed shall at a minimum meet the number of landscaping points
specified in Figure 300-8.30d.
(2)
Tall trees shall not be used to meet building foundation landscaping
requirements.
(3)
Building foundation landscaping shall be placed so that at maturity,
the plant’s drip line is located within 10 feet of the building
foundation.
(4)
Building expansions shall be subject to the same landscaping
formula requirements as new buildings (see Figure 300-8.30d). The
formula shall not be applied to portions of the building foundation
developed prior to the adoption of this chapter.
(5)
The measurement of the building foundation may be simplified
as the smallest single rectangle that contains the entire building
perimeter, except that the sides of the building facing an adjacent
public street, where the actual perimeter shall be measured.
B.
Paved areas.
(1)
For every 10 off-street parking stalls or 10,000 square feet
of pavement (whichever yields the greater landscaping requirement),
landscaping shall at a minimum meet the number of landscaping points
specified in Figure 300-8.30d.
(2)
Paved area landscaping shall be placed so that at maturity,
the plant’s drip line is located within 10 feet of the paved
area. Said area does not have to be provided in one contiguous area.
Plants used to fulfill this requirement shall visually screen parking,
loading, and circulation areas from view from public streets.
(3)
A minimum of 30% of all points shall be devoted to medium or
tall trees, or a combination of such trees, and a minimum of 40% of
all points shall be devoted to shrubs.
(4)
Parking lot design.
(a)
Interior parking lot landscaping shall be required for any parking
lot with more than 20 parking spaces. Internal parking lot landscaping
shall be accomplished by the installation of landscaped planter islands
or other types of landscaping application approved by the Building/Zoning
Inspector.
(b)
Landscaped planter islands.
[1]
Landscaped planter islands shall be required at
the ends of all parking rows, driveway entrances, and at intermediate
locations such that there is a maximum of 180 feet between islands.
See Figure 300-8.30a.
[2]
Landscaped planter islands are required where two
rows of parking stalls meet at a right angle. See Figure 300-8.30b.
|
Figure 300-8.30a
Requirements for Islands
 |
|
Figure 8.30b
Parking Rows at Right Angles
 |
(c)
Each landscaped planter island shall be no less than 125 square
feet in area and seven feet in width, measured from the back of the
curb. For double-parking rows, each landscaped planter island shall
be no less than 250 square feet in area. The seven-foot width requirement
may be reduced to accommodate the triangular shape resulting from
angled parking.
(d)
All islands shall be crowned for positive drainage, unless bio-retention
methods of stormwater management are utilized per a stormwater management
plan approved by the City Engineer.
(e)
One shade tree or tall deciduous tree shall be provided for
every island and for every 40 linear feet of continuous landscape
strip. Medium or low trees (evergreen or deciduous) may be used to
supplement deciduous shade trees in locations that may not support
healthy shade tree or tall deciduous tree growth. This determination
shall be made by the Building/Zoning Inspector. For double-row parking,
two shade trees or tall deciduous trees shall be required for each
island.
(f)
In addition to the required trees and shrubs, islands shall
be planted with grass, low ground cover, shrubs, flowers, decorative
stone/river rock, mulch, or a combination thereof. Mulches and decorative
stone shall be installed so that the loose material will not erode,
fall, be plowed, or be otherwise transported onto paved surfaces.
(g)
To ensure proper visibility within the parking lot, shrubs shall
be no higher than two feet and the branches of trees shall start no
less than six feet from the ground, unless located in areas that do
not affect driver visibility.
(5)
Parking lot screening required by § 300-6.06I shall count toward the landscaping requirements of this section.
(6)
Paved area expansions shall be subject to the same landscaping
formula requirements as new paved areas (see Figure 300-8.30d). The
formula shall not be applied to paved areas developed prior to the
adoption of this chapter.
C.
Street frontages.
(1)
For every 100 linear feet of the longest street frontage of
a developed lot abutting a public street right-of-way, the landscaping
installed shall at a minimum meet the number of landscaping points
specified in Figure 300-8.30d.
(2)
Street frontage landscaping shall be placed so that at maturity,
the plant’s drip line is located within 10 feet of the public
street right-of-way.
(3)
Landscaping shall not be located within a public right-of-way. Landscaping shall not impede vehicle or pedestrian visibility. See § 300-6.05.
(4)
A minimum of 50% of all points shall be devoted to decorative
or medium trees, or a combination of such trees.
(5)
In the case of any new principal building, building expansion,
new paved area, or paved area expansion on a previously-developed
site, a percentage of the landscaping points specified in Figure 300-8.30d
shall be required. For new paved areas and expansions, the required
percentage shall be equal to the percentage of the paved area expansion
as compared to the existing paved area square footage. For new buildings
and expansions, the required percentage shall be the percentage of
the building expansion as compared to the existing building square
footage.
D.
Yards.
(1)
For every 1,000 square feet of gross floor area of all principal
and accessory buildings on the site, the landscaping installed shall
at a minimum meet the number of landscaping points specified in Figure
300-8.30d.
(2)
Landscaping required by this section is most effective if located
away from other areas required for landscaping such as building foundations,
street frontages, paved areas, protected green space areas, or bufferyards.
(3)
The intent of this section is to provide yard shade and to require
a visual screen of a minimum of six feet in height for all detached
exterior appurtenances (such as HVAC, utility boxes, standpipes, stormwater
discharge pipes and other pipes).
(4)
Building expansions shall be subject to the same landscaping
formula requirements as new buildings (see Figure 300-8.30d). The
formula shall not be applied to portions of buildings developed prior
to the adoption of this chapter.
E.
Bufferyards. A bufferyard is a combination of distance and a visual
buffer or barrier. It includes an area, together with the combination
of plantings, berms and fencing that are required to eliminate or
reduce existing or potential nuisances (e.g. dirt, litter, noise,
glare, signs, and incompatible land uses, buildings, or parking areas).
(1)
The required level of bufferyard opacity is listed in Figure
300-8.30e. Detailed bufferyard requirements are listed in Figure 300-8.30f.
Opacity is a quantitatively-derived measure which indicates the degree
to which a particular bufferyard screens the abutting property. The
required level of opacity indicated is directly related to the degree
to which the potential character of development differs between different
zoning districts.
(2)
Bufferyards shall be located along (and within) the outer perimeter
of a lot wherever two different zoning districts abut one another.
Bufferyards shall not be required in front yards or along public street
frontages.
(3)
To ensure that the year-round screening objectives are fulfilled,
only the plant classifications in Figure 300-8.40b listed as “appropriate
for screening” shall count toward bufferyard point totals, unless
non-screening plants are used in combination with a solid fence or
a berm of six feet or more, in accordance with Figure 300-8.30f.
(4)
Reduction of required bufferyard width.
(a)
Intent. This subsection is intended to allow for the reduction
of the required width of a required bufferyard where the presence
of permanently protected green space or similar areas provides equivalent
permanent screening and separation benefits as would be provided by
the otherwise required bufferyard.
(b)
Where the minimum permitted width for the required bufferyard
is not available under the current or proposed state of development,
the Planning Commission, may reduce the width required for the bufferyard
to that currently available on the site, provided that the portion
of the site that requires a bufferyard contains one or more of the
following:
[1]
Steep slopes that contain retaining walls or rip-rap.
[2]
Permanently undevelopable green space or other
permanently protected green space designated on site plans such as
a native or restored prairies or park savannas, wetlands, bodies of
water, floodplains, drainageways, upland woods, stormwater basins,
or other natural resource protection areas, including areas protected
by covenants or conversation easements.
(c)
If there is permanently protected green space located on an
adjoining property adjacent to the portion of a site that requires
a bufferyard, the Planning Commission, may reduce the width required
for the bufferyard. The reduction shall consist of no more than one
foot for every three feet of permanently protected green space on
the adjoining property, as measured from the property line at a right
angle into said adjacent property. There shall be no reduction in
the number of landscape points required.
(5)
Use of required bufferyard and landscaped areas.
(a)
Any and all required bufferyards or landscaped areas may be
used for passive recreation activities. Said areas may contain pedestrian
or bike trails provided that no required landscaping material is eliminated;
the total width of the required bufferyard, or the total area of required
landscaping, is maintained; and all other regulations of this chapter
are met.
(b)
No swimming pools, tennis courts, sports fields, golf courses,
or other such similar active recreational uses shall be permitted.
(c)
No parking, buildings, outdoor light fixtures, and no outdoor
display of storage of materials shall be permitted.
(d)
Paving in such areas shall be limited to that required for necessary
access to or across the subject property or for a passive recreational
use such as paved multiuse trails or pedestrian walkways.
F.
Determination of landscaping requirements.
(1)
The requirements of this article are additive to each other
and any other landscaping or screening requirements in this chapter.
(2)
Landscape points used to meet one requirement (e.g. building
foundations, paved areas, street frontages, yards, or bufferyards)
shall not be used to meet another requirement.
G.
Measurement and calculation.
(1)
Landscaping point values shall be doubled for mature existing
landscape plantings that are retained and protected with the development
of the site. Existing plantings eligible for double point values shall
be determined by the Building/Zoning Inspector.
(2)
In calculating the number of required landscaping points under
the provisions of this section, all areas and distances on which required
calculations are based shall be rounded up to the nearest whole number
of square feet or linear feet.
(3)
Any partial plant derived from the required calculations of
this section (for example: 23.3 shade trees) shall be rounded up to
the next whole plant (for example: 24 shade trees).
H.
Utility easements. Landscaping materials, fences and berms located
within a duly recorded utility, stormwater, or a pedestrian easement
shall not count toward meeting a landscaping requirement, unless authorized
otherwise by the City and the easement holder. However, the width
of such areas may be counted as part of a landscaping width requirement
for bufferyards.
I.
Other green space areas. Green space areas not used for landscape
plantings other than natural resource protection areas shall be graded
and seeded or sodded with an acceptable maintainable seed mix, restored
to native vegetation. Alternatively, such areas may be maintained
in crop production if a principal use exists on-site and if approved
by the Building/Zoning Inspector.

Fences contributing to landscaping requirements are not permitted
along street frontages for nonresidential uses. Where used in combination
with plant materials to meet bufferyard requirements, a minimum of
50% of all plant materials shall be located on the exterior side (the
side away from the center of the subject property) of the fence. A
building wall which does not contain doors (except those used for
emergency exit) may be used to satisfy the required fence portions
of the bufferyard requirements.

|
Any existing on-site mature tree that is protected with no impervious
surface or grading within its canopy is worth three times the point
value as provided in this table. If said tree dies, it shall be replaced
with the comparable new tree landscaping points as provided in this
table.

Species suitable for landscaping and compatible with local climate
and soil factors are listed in Figure 300-8.40a. Plant species native
to Wisconsin are noted by an asterisk (*). This list is not intended
to be exhaustive, and the Building/Zoning Inspector, shall review
proposals for the applicability of species not listed and is authorized
to approve appropriate similar species. See Figure 300-8.40b for species
appropriate for specific and common landscaping situations (e.g.,
planting under power lines), and Figure 300-8.40c for a list of species
to use sparingly or to avoid.

NOTES:
| |
|
1
|
“Species to use sparingly” may be used as part of
an overall landscaping plan, but only if the number of individual
plants does not constitute more than one plant per 20 total plants
within the same plant classification. For example, if a landscaping
plan includes a total of 20 tall deciduous trees, no more than one
of those 20 trees may be classified as a “species to use sparingly.”
The purpose of this provision is to encourage plant species diversity
throughout the City.
|
|
2
|
“Prohibited species” shall not be included as part of any landscaping plan that is subject to City review per § 300-10.20. The purpose of this provision is to limit the planting of species that are invasive, have invasive tendencies, or that may perpetuate or spread disease.
|
A.
Definition.
(1)
Rain gardens can serve both as landscaping and stormwater management
features on a building site, where appropriately designed and sited.
A rain garden is a shallow, depressed garden that is designed and
positioned on a site to capture stormwater runoff and allow for the
infiltration of water back into the ground. Rain garden plants are
carefully chosen for their ability to withstand moisture extremes
and potentially high concentrations of nutrients and sediments that
are often found in stormwater runoff. A well designed and maintained
rain garden serves as an attractive component of an overall landscaping
plan for a development site.
(2)
Bioswales can serve both as landscaping and stormwater management
features on a building site, where appropriately designed and sited.
A bioswale is a linear, vegetative stormwater runoff conveyance system
that is designed to store and infiltrate water from small storm events
back into the ground and direct water from heavy rain events to appropriate
storm sewer inlets or other management facilities. The flow of water
being conveyed through a bioswale is slowed down, allowing for municipal
storm systems to more effectively manage heavier rain events and help
reduce the risk of flooding on or off-site. Water being infiltrated
or conveyed via a bioswale is also filtered by the vegetation within
it, generally improving both ground and surface water quality.
B.
Requirements.
(1)
The installation of a rain garden or bioswale may contribute
to the overall stormwater management plan for a development site and
count toward meeting the City’s landscaping guidelines. Rain
gardens and bioswales may count for 20 points for every 20 square
feet for yard, building foundation, and/or paved area requirements,
provided the following requirements are met. Rain gardens and bioswales
shall count for no more than 100 points of the required landscaping
per site.
(2)
Detailed plans shall be provided that show all proposed dimensions
of the rain garden or bioswale including length, width, depth, and
slope of depression; location of the rain garden or bioswale on the
lot relative to hard-surfaced areas, downspouts, and site topography;
characteristics of the soil underlying the rain garden or bioswale;
description of planting media; the species, number, and size at time
of installation of all vegetation proposed for the rain garden or
bioswale; and information on any other materials that will be used
to line the rain garden or bioswale.
(3)
Installation shall not be proposed for any of the following
areas of a site:
(a)
Areas where there is known soil contamination unless the rain
garden or bioswale is proposed to be constructed with an under-drain;
(b)
Areas where the characteristics of the soil would not allow
for the proper infiltration, as defined by the Wisconsin Department
of Natural Resources, of water into the ground; or
(c)
Areas where there are expected to be high levels of foot traffic,
unless such areas are protected from foot traffic.
(4)
The owner of the site shall record a maintenance agreement with
the City if utilized for required stormwater management on the site.
Specifically: kept free of trash, weeds, debris, and dead or dying
plants; any pipes associated with the rain garden or bioswale will
be inspected on an annual basis and kept free of debris; and by the
beginning of every spring dead plant materials will be cut back or
removed.
(5)
Bioswales and rain gardens shall be generously (and appropriately)
vegetated to qualify for landscaping points. If bioswales and rain
gardens (or portions thereof) are lined with turf but do not include
other vegetation, then they will not count toward meeting landscaping
point requirements.
(6)
Rain gardens and bioswales may serve as a component of an overall
stormwater management plan for a site only if detailed plans, calculations,
and specifications are submitted and approved by the City Engineer.
Detailed plans shall include the location and description of all other
stormwater management facilities serving the site, particularly those
to which any bioswale will be directed.
A.
Installation.
(1)
Any and all landscaping and bufferyard material required by the provisions of this chapter shall be installed on the subject property, in accordance with the approved site plan within 365 days of the issuance of an occupancy permit for any building on the subject property, unless specified below in Subsection A(2). Failure to comply with this requirement shall be subject to the fees and penalties in §§ 300-10.60 and 300-10.61.
(2)
For any lot less than one acre in size or for any building less
than 10,000 square feet, any and all landscaping and bufferyard materials
required by the provisions of this chapter shall be installed on the
subject property, in accordance with the approved site plan within
730 days of the issuance of any occupancy permit for any building
on the subject property.
B.
If existing plant material meets the requirements of this article
and will be preserved on the subject property following the completion
of development, it may be counted as contributing to the landscaping
requirements and worth double the landscaping point value per plant.
C.
All landscaping and bufferyard areas shall be seeded with lawn or
native ground cover unless such vegetation is already fully established.
D.
The exact placement of plants and structures shall be depicted on
the required detailed landscaping plan submitted to the City for its
approval. Such plant and structure location shall be the decision
of each property owner provided the following requirements are met:
(1)
Evergreen shrubs shall be planted in clusters to maximize their
chance for survival.
(2)
Where a combination of plant materials, berming, and fencing
is used in a bufferyard, the fence and/or berm may be located toward
the interior or exterior of the subject property and at least 50%
of the required landscaping points shall be located toward the exterior
of the subject property.
(3)
A property owner may establish through a written agreement,
recorded with the Register of Deeds that an abutting property owner
agrees to provide on the immediately abutting portion of his or her
land a partial or full portion of the required bufferyard, thereby
relieving the developer of the responsibility of providing the entire
bufferyard on his property. Responsibility for maintenance of bufferyard
landscaping shall be included as part of this agreement.
(4)
Under no circumstance shall landscaping or bufferyard materials
be selected or located in a manner resulting in the creation of a
safety or visibility hazard.
(5)
The restrictions on types of plants listed in this article shall
apply.
E.
Upon completion of the approved landscape improvements, a certification
of compliance shall also be submitted by the owner or agent.
F.
Maintenance.
(1)
The continual maintenance of all required landscaping and bufferyard
materials shall be a requirement of this chapter and shall be the
responsibility of the owner of the property on which said materials
and plants are required. This requirement shall run with the property
and shall be binding upon all future property owners. Development
of any or all property following the effective date of this chapter
shall constitute an agreement by the property owner to comply with
the provisions of this section.
(2)
The owner of the premises shall be responsible for the watering,
maintenance, repair, and replacement of all landscaping, fences, and
other landscape architectural features on the site. All planting beds
shall be kept weed-free. Plant material which has died shall be replaced
with equivalent vegetation within 12 months.
