A.
Landscaping required. Landscaping is required in peripheral buffer yards, street buffer yards, for on-lot landscaping, in off-street parking areas, and in areas where vegetative mitigation (see § 500-111 of this chapter) is required. The area and/or length of each, as required herein, must be measured in order to determine the amount of landscaping required.
B.
Exemptions and modifications. All developments shall meet the provisions
of this article, except as specifically exempted below:
(1)
Residential development on existing lots of record in the EA,
AT, GA, HFA, R-1, R-2, R-3, R-4, R-5, R-6, R-7 and R-8 Districts.
Residential development on existing lots of record in the EA, AT,
GA, HFA, R-1, R-2, R-3, R-4, R-5, R-6, R-7 and R-8 Districts as of
the date of the adoption of this chapter.
[Amended 4-19-2011 by Ord. No. 11-001]
(2)
Additions to existing buildings where the total floor area is
not increased more than 10%. Additions to existing buildings where
the total floor area is not increased more than 10% of the existing
total floor area.
(3)
Additions to buildings which increase overall building area
from 10% to 50%. Additions to buildings which increase their overall
building area from 10% to 50% shall conform to the landscaping standards
specified in this article to the maximum extent possible. All off-street
parking areas and buffer yards shall conform to the landscaping requirements
of this article. If insufficient dimensions exist on site, in order
to achieve a sufficient level of landscaping, the standards set forth
in this article may be reduced by up to 30% by the Plan Commission.
(4)
Floodplain, floodway, floodlands, and wetland areas. Areas located
within floodplains, floodways, floodlands and wetlands are exempt
from the landscaping requirements set forth in this article.
C.
Buffer yards to ameliorate nuisances between certain adjacent zoning
districts. A buffer yard is a combination of a setback and a visual
buffer or barrier and is a yard or area, together with the planting
and/or landscape structure required thereon. The amount of land, the
type of planting, and the amount of planting specified for each buffer
yard requirement of this chapter are designed to ameliorate nuisances
between certain adjacent zoning districts. Buffer yards are also designed
to ensure a desired character along public streets and roads.
D.
Buffer yards required to separate different zoning districts. Buffer
yards shall be required to separate different zoning districts from
each other. Buffer yards function to eliminate or minimize potential
nuisances such as dirt, litter, noise, glare of lights, signs, and
unsightly buildings or parking areas or to provide spacing to reduce
adverse impacts of noise, odor, or danger from fires or explosions.
All landscaping requirements are stated in terms of the number
of standard plant units required. This section defines the standard
plant unit and its alternatives. All required landscaping shall conform
to one or more of the plant unit alternatives of this section. The
following Table 500-127 specifies the plant unit alternatives. In
general, the five alternative plant mixes are interchangeable. In
other cases, where a year-round variety is required, alternative Unit
A is preferred and may even be specified by the Plan Commission. Where
a year-round screen is required, Type D shall be used.

Credit for existing plant material will be allowed to offset
required plant unit landscaping in the buffer yards and parking lots
as follows:
A.
Buffer yards. Where the buffer yard is to be left in a natural state,
no shrubs shall be required. Individual trees six feet in height or
more shall be counted on an individual basis towards the planting
requirements; other components of a plant unit are required, including
all shrubs.
B.
Parking lots. Any existing trees six feet in height or more shall
be subtracted from the required area amount of parking lot landscaping
on a tree-by-tree basis.
C.
Plant
material substitution. Required landscape plant material types may
be substituted for other types based upon the requirements of Table
500-128.[1]

[Amended 11-1-1995 by Ord. No. 95-2]
A.
Physical containment of landscaped areas. All landscaped areas located
within or adjacent to a parking area or adjacent to a public street
or sidewalk shall be designed to contain landscape materials and to
prevent vehicular encroachment (i.e., through the use of continuous
concrete curbing, railroad ties, headers, or depressed construction).
B.
Artificial landscape materials. Artificial trees, shrubs, turf, or
plants shall not be permitted as landscaping.
C.
Ground cover. The use of landscape fabrics under all areas landscaped
with nonliving materials, except those areas set aside for stormwater
retention/detention, is recommended to prevent weed growth.
D.
Location. New vegetation shall be selected, planted, and maintained
so that at maturity it will not interfere with utility lines, snow
storage areas, vehicular parking, pedestrian circulation, traffic
sight visibility at driveways and street intersections and will not
cause damage or upheaval of sidewalks and pavement.
E.
Installation.
(1)
Timing of installation. Landscaping and watering devices shall
be installed in accordance with the approved landscape plan prior
to issuance of a zoning permit or commencement of operations. The
Town of Barton will have the right to refuse approval of any project
not meeting the provisions of this section.
(2)
Financial surety required. If approved landscaping and watering devices cannot be installed prior to occupancy or commencement of operations, a zoning permit may be issued by the Town of Barton if the applicant provides an acceptable form of surety meeting the requirements set forth in § 500-151 of this chapter. The application shall be accompanied by a complete estimate of the total cost of the approved landscaping and watering system improvements prepared by a landscape architect. All landscape materials shall be guaranteed for two years.
(3)
Return of financial surety. When it is determined that the landscaping
and watering system have been installed in accordance with the approved
plans, the Town of Barton shall return the surety to the applicant.
F.
Maintenance.
(1)
Responsibility for maintenance.
(a)
Maintenance of all landscaping shall be the responsibility of
the owner, lessee, heirs, assigns, agents, homeowners' association,
or other liable entity of the property and shall consist of regular
watering, pruning, mowing, fertilizing, the removal and replacement
of irrigation systems, and architectural features.
(b)
The owner or liable entity in control of any private premises
shall at all times maintain the premises free of litter and weeds.
(2)
Landscape phasing. Future building pads within a phased development
shall be maintained in a dust-free condition vegetated with ground
cover.
(3)
Plant replacement. Any plant materials included in an approved
landscaping plan that do not survive a plant establishment period
of two years after installation shall be replaced with plant material(s)
of the same or like species of equal size within the next planting
season, but in any event, within six months of the plant's demise.
Said replacement shall be made by the property owner or, in the case
of landscape plant materials located within a landscape easement under
the control of a homeowners' association, the homeowners' association
shall be responsible for said replacement.
A.
General.
(1)
Buffer yard standards are listed in this section for peripheral
buffer yards and for street buffer yards.
(2)
Peripheral and street buffer yard standards are based on a required
buffer yard intensity factor value. A variety of combinations of buffer
yard width, planting intensity, and structural options (i.e., fences
and earthen berms) may be selected from Table 500-134 to reach the
required buffer yard intensity level value.
(3)
Peripheral buffer yards shall be located along the outer perimeter
of a lot or parcel and shall extend to the lot or parcel boundary
line. Peripheral buffer yards shall not be located on any portion
of an existing or dedicated public or private street or right-of-way.
(4)
Required buffer yard plantings may be planted in natural-appearing
groupings along the total length of the buffer yard and need not be
spaced uniformly along said total buffer yard length.
B.
Plant materials.
(1)
For each buffer yard listed, a specific combination of canopy, shade, and understory trees, evergreen trees, and shrubs is required as indicated in § 500-127.
(2)
All buffer yard areas shall be seeded with lawn or native ground
cover, unless such vegetation is already fully established.
(3)
The exact placement of required plants and structures shall
be the decision of the property developer.
C.
Fences. Fences shall be constructed of rock, masonry, or wood. Chain-link fences and chain-link with slats shall be prohibited from use in required buffer yards. All fences used shall also meet the requirements for the construction of fences as set forth in Article XI of this chapter.
D.
Height of required vegetation. Height of vegetation selected for
required buffer yards shall be measured from the highest finished
adjacent grade of the element to be screened.
E.
Berming. Earthen berms shall be designed to transition to existing
grades, not to exceed a slope ratio of 2:1, and shall be covered with
plant material, ground cover, or partially riprapped to prevent erosion.
Berms with vegetative cover shall be designed to retain irrigation
water rather than encourage runoff. All earthen berms shall be safely
designed in order to accommodate mowing when needed.
F.
Calculation of buffer yard requirements.
(2)
Buffer yard standards listed in this section are to be calculated
for every 100 linear feet of peripheral lot line boundary and/or street
frontage present on a given lot.
(3)
In instances where the zoning district boundary and/or street
frontage is less than 100 feet, the required buffer yard planting
shall be one plant unit. (See Table 500-127.)
(4)
To determine the type of buffer yard required on a parcel, between
two parcels or lots, or between a parcel or lot and a street, the
following procedures shall be used:
(a)
Procedures for determining minimum required peripheral buffer
yards:
[1]
Identify whether any portion or property line of the parcel
or lot coincides with a zoning district boundary. If it does, determine
the abutting zoning districts on both sides of the property line.
[2]
Refer to § 500-132 to determine the required buffer yard intensity factor needed to be achieved between the two zoning districts.
[3]
Based upon the buffer yard intensity factor required, refer
to the applicable Table 500-134A to 500-134E to select the minimum
number of plant materials (per 100 feet of buffer yard length), the
buffer yard width, and required structure type combination by selecting
the desired alternative buffer yard type.
[4]
Calculate the actual number of plants required by selecting
the minimum number of plant materials (per 100 feet of buffer yard
length) from the alternatives indicated the applicable Table 500-134A
to 500-134E and multiply by the hundreds of feet of buffer yard to
be planted. Calculations resulting in fractional numbers of plant
materials required shall be rounded to the next higher whole number.
The minimum required buffer yard intensity level factor values
for peripheral buffer yards between zoning districts set forth in
the Table 7 at the end of this chapter refer to the buffer yard width
and plant unit standards set forth in Table 500-134 of this article.
Peripheral buffer yards are required between adjacent zoning districts.
The abbreviations used in Table 7 represent the Town of Barton zoning
district designations used throughout this chapter.
[Amended 4-19-2011 by Ord. No. 11-001; 10-21-2014 by Ord. No. 14-003]
The numbers given in Table 500-133 refer to the various buffer yard intensity level factors described in Table 500-134 of this chapter. Any combination of vegetation, structure(s), and width set forth in Table 500-134 may be selected, provided the required buffer yard intensity level factor is met as required by § 500-132 of this chapter. The abbreviations used in Table 500-133 represent the Town of Barton zoning district designations used throughout this chapter.

B.
Existing vegetation may count towards the provision of minimum off-street
parking landscape requirements. Existing trees that can be preserved,
where grading does not cut them off from a reasonable supply of water
and where the area under the canopy remains undisturbed, shall count
towards the plant requirements by measuring the area of the island.
The minimum size of such an island shall be 300 square feet. Table
500-135A specifies the minimum area requirements per 24 required off-street
parking spaces or fraction thereof.
C.
Curbs, barriers, and overhangs required to contain landscape areas.
The curb or barrier around landscape areas may be utilized as a wheel
stop, provided the area of vehicle overhang does not exceed two feet
and does not damage or interfere with the landscaping. Where vehicle
overhangs abut required landscape areas, a minimum five-foot-wide
planter is required for a single vehicle overhang and an eight-foot-wide
planting area is required for a double vehicle overhang. Vehicle overhang
into the public right-of-way is not permitted.
D.
Uses not permitted in required landscaped areas. Parking (except
where vehicle overhang is permitted), buildings, and display of equipment
or vehicles are not permitted in required landscaped areas.
E.
Required landscape materials not to constitute a driving hazard.
To ensure that landscape materials do not constitute a driving hazard,
trees used to landscape parking islands shall have a clear trunk height
of six feet; mature shrubs, ground cover, or other landscaping material
shall not exceed three feet in height. The landscaped area within
these planters may be used to satisfy, to the extent provided, the
landscaping requirements.
A.
Minimum on-site landscaping required. Each residential and nonresidential zoning district or lot in a new development shall contain a minimum amount of landscaping in areas not designated as off-street parking under the provisions of §§ 500-117 and 500-135, buffer yards under §§ 500-130 through 500-134 of this chapter, or areas designated as buildings. For each acre of land not occupied by buildings, off-street parking areas, drives, or buffer yards, the number of Type B plant units as described in Table 500-127 shall be planted. In the case of residential buildings, the requirement shall be for every parcel, lot, or dwelling unit, whichever results in a greater amount of plant materials.
B.
Deed-restricted open space and undisturbed resource protection areas
excluded. No area that is undisturbed and designated as open space
required under the open space or natural resource protection provisions
of this chapter, and other deed-restricted residential open space
meeting open space ratio (OSR) requirements of this chapter, or is
designated as an undisturbed resource protection area and protected
by deed restrictions, shall be included in the calculation of the
area to be planted.
C.
Minimum required on-site landscaping. For residential and all nonresidential
zoning district parcels and lots, the minimum amount of on-site landscaping
set forth in Table 500-136C shall be provided in addition to all other
required buffer yard landscaping and off-street parking landscaping.

A.
General plant material standards. All new landscape plant material
shall be grown in a nursery located in Plant Hardiness Zone 4 and
shall conform to the applicable requirements as specified in the current
edition of American Standard for Nursery Stock as approved by the
American National Standards Institute, Inc., and sponsored by the
American Association of Nurserymen, Inc. Botanical plant names shall
be in accordance with the current edition of Standardized Plant Names
prepared by the American Joint Committee on Horticultural Nomenclature.
B.
Plant material minimum size standards. All required new landscape
plant material shall be, at the time of installation, those minimum
sizes as set forth in Table 500-137B.

The Town of Barton recognizes that the use of the landscape
surface ratio (LSR) standards for the provision of adequately landscaped
open space in nonresidential areas as set forth in this chapter may
not always lead to good design and, under some circumstances, may
be difficult to achieve. This section addresses landscape mitigation
measures which may be allowed by the Plan Commission.
A.
Mitigation of required buffer yards and off-street parking landscaping
not permitted. The mitigation of the dimensional requirements, structural
requirements, and/or landscape plant unit and/or material requirements
of required peripheral or street buffer yards shall not be allowed.
Landscape surface ratio (LSR) mitigation shall only be allowed for
required on-site landscaping as required in Table 500-136C.
B.
Maximum allowable reduction of the landscape surface ratio (LSR) through mitigation measures. The maximum allowable reduction of the landscape surface ratio (LSR) through mitigation measures shall not fall below those landscape surface ratios (LSRs) set forth in Table 500-139. In no case shall reductions in landscape surface ratios (LSRs) supersede the natural resource protection standards set forth in Article XV or allow for increases in either the maximum gross floor area ratio (GFAR) or net floor area ratio (NFAR) set forth in the various zoning district requirements of this chapter.
