The purpose of this article is to establish landscaping requirements and other regulations intended to preserve and maintain vegetation in a manner that promotes the natural resource protection, aesthetic, and public health goals of the Village of East Troy. Any nonconforming situation (lot, use, structure and/or site) shall adhere to the provisions of Article IX.
A.
This article contains the standards which govern the amount, size,
type, installation and maintenance of required landscaping. This article
recognizes the important and diverse benefits which landscaping provides
in terms of protecting the health, safety, and general welfare of
the community.
B.
Each section of this article is oriented to a specific category of
required landscaping. The landscaping requirements described in this
article are cumulative in nature and are required for all development,
except single-family residential and agricultural uses, in the following
locations: around building foundations, in developed lots, along street
frontages, in or around paved areas, in permanently protected green
space areas, in reforestation areas, and in bufferyards.
All landscaping requirements are stated in terms of the number
of landscaping points required. The required number of landscaping
points is dependent upon the type of land use, the zoning district,
and the size of the development. Points are awarded based on plant
type, which is dependent upon its typical growth rate, its mature
height, and whether it is a deciduous or evergreen species. Figure
510-114 itemizes the number of points awarded per plant type and the
minimum installation size required for each of these plant categories.

A minimum
amount of landscaping points, based upon the zoning district, is required
for the linear feet of building foundations; the gross area of buildings
on developed lots; the linear feet of street frontage; and the total
combined area of paved areas. Figure 510-115B illustrates the measurement
techniques used to determine these requirements.

Landscaping calculation equations for this example:
Paved area = (P1 x P2) + (P3 x P4) + (P5 x P6) + (P7 x P8) + (P9 x P10)
Street frontage = S1 + S2
Building perimeter = F1 + F2 + F3 + F4 + F5 + F6 + F7 + F8
Building floor area = (B1 x B2) + (B3 x B4) + (B5 x B6)
|
A.
Building foundations. As indicated in Figure 510-116,[1] certain buildings or building additions constructed after
the effective date of this chapter are required to be accented by
a minimum amount of landscaping placed near the building foundation.
(1)
Foundation landscaping shall be placed so that, at maturity, the plant's drip line is located within 10 feet of the building foundation. Such landscaping shall not be located in those areas required for landscaping as street frontages, paved areas, protected green space areas, reforestation areas, or bufferyards. Foundation landscaping shall be installed and permanently maintained in conformity with the requirements of §§ 510-121 and 510-122.
(2)
For each 100 feet of building foundation perimeter, the landscaping installed shall at a minimum meet the number of landscaping points specified in Figure 510-116. The actual number of points required for such landscaping shall be computed on a prorated basis and installed and permanently maintained per the requirements of §§ 510-121 and 510-122.
(3)
Climax trees and tall trees shall not be used to meet the foundation
landscaping requirement. The intent of this section is to require
a visual break in the mass of buildings and to require a visual screen
of a minimum of six feet in height for all exterior perimeter appurtenances
(such as HVAC/utility boxes, standpipes, stormwater discharge pipes
and other pipes).
(4)
If the officially approved site plan depicts a future building
extension, the foundation landscaping requirement shall be calculated
by measuring the length of the total perimeter. However, foundation
plantings need only be installed based on the landscape points calculated
from the portions of the building perimeter that will not be affected
by building extension. If this results in a point requirement not
met by the initial planting, then the requirement shall be met within
five years after the issuance of the building permit or within such
larger time period as established in writing by the Plan Commission.
[1]
Editor's Note: Figure 510-116 is included as an attachment to this chapter.
B.
Street frontages. As indicated in Figure 510-116, street frontages
on certain lots developed after the effective date of this chapter
must contain a minimum amount of landscaping in those areas abutting
the right-of-way of a public street.
(1)
All landscaping used to meet street frontage requirements shall be located within 10 feet of the public right-of-way. Under no circumstances shall such landscaping be located within a public right-of-way. Landscaping shall not impede vehicle or pedestrian visibility and shall be installed and permanently maintained in conformity with the requirements of §§ 510-121 and 510-122.
(2)
For every 100 linear feet of street frontage of a developed lot abutting a public street right-of-way, the landscape installed shall at a minimum meet the number of landscaping points specified in Figure 510-116. The actual number of points required for such landscaping shall be computed on a prorated basis and installed and maintained per the requirements of §§ 510-121 and 510-122.
(3)
Shrubs shall not be used to meet street frontage landscaping
requirements. A minimum of 50% of all points shall be devoted to climax
or tall trees, or a combination of such trees, and a minimum of 30%
of all points shall be devoted to medium trees.
C.
Paved areas. As indicated in Figure 510-116, paved areas on certain
lots developed after the effective date of this chapter must contain
a minimum amount of landscaping within 10 feet of the paved area.
The intent is to require a continuous visual screen of parking areas
from public rights-of-way at a minimum height of 40 inches.
(1)
A minimum of 360 square feet of landscaped area, which shall be located within 10 feet of the paved area, is required for the placement of every 100 paved area landscaping points. Said area does not have to be provided in one contiguous area. Sample configurations are depicted in Figure 510-115A above. Plants used to fulfill this requirement shall visually screen parking, loading and circulation areas from view from public streets. Paved area landscaping shall be installed and permanently maintained in conformity with the requirements of §§ 510-121 and 510-122.
(2)
For every 20 off-street parking stalls or 10,000 square feet of pavement (whichever yields the greater landscaping requirement) located in a development, the landscaping installed shall at a minimum meet the number of landscaping points specified in Figure 510-116. The actual number of points required for such landscaping shall be computed on a prorated basis and installed and maintained per the requirements of §§ 510-121 and 510-122.
(3)
A minimum of 30% of all points shall be devoted to climax 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 shall employ interior landscaped islands
with a minimum of 400 square feet at all parking aisle ends and in
addition shall provide a minimum of one landscaped island of a minimum
of 400 square feet in each parking aisle for every 20 cars in that
aisle. Aisle-end islands shall count toward meeting this requirement.
Landscaped medians shall be used to break large parking areas into
distinct pods, with a maximum of 100 spaces in any one pod.
D.
Developed lots. As indicated in Figure 510-116, lots developed after
the effective date of this chapter must contain a minimum amount of
landscaping.
(1)
Landscaping required by this section is most effective if located
away from those areas required for landscaping as building foundations,
street frontages, paved areas, protected green space areas, reforestation
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).
This section requires that each acre of other permanently protected green space after the effective date of this chapter be planted with a minimum amount of landscaping. For every one acre of other permanently protected green space in a development, 200 landscaping points (as described in § 510-114) shall be provided. In addition, adequate ground cover shall be provided to stabilize the soil.
This section requires that each area requiring reforestation be reforested and maintained in a manner appropriate to site conditions. The provisions of this section are designed to ensure that reforestation efforts required as part of woodland disruption mitigation standards result in the thorough and reasonably rapid replacement of the important and varied environmental functions that woodlands provide. A detailed reforestation plan shall be submitted by the property owner and approved by the Village prior to clear-cutting (see § 510-40E). This plan shall be reviewed by a reforestation consultant chosen by the Village, with funding for consulting services provided by the petitioner to the Village.
A.
Purpose. This section provides the landscaping and width requirements
for bufferyards on lots developed after the effective date of this
chapter. 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. These nuisances can often occur between adjacent
zoning districts. Such nuisances are dirt, litter, noise, glare, signs,
and incompatible land uses, buildings, or parking areas.
B.
Required locations for bufferyards. 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.
C.
Determination of required bufferyard opacity. The required level
of bufferyard opacity is determined using Figure 510-119A.[1] Opacity is a quantitatively derived measure which indicates
the degree to which a particular bufferyard screens the adjoining
property. The required level of opacity is directly related to the
degree to which the potential character of development differs between
different zoning districts. The provisions of this section indicate
the minimum opacity requirements for bufferyards located along zoning
district boundaries.
[1]
Editor's Note: Figure 510-119A is included as an attachment to this chapter.
D.
Identification of detailed bufferyard requirements. If a proposed
use adjoins a parcel for which a bufferyard is required by the presence
of a zoning district boundary, that use shall provide a bufferyard
with the level of the opacity indicated in Figure 510-119A. For each
level of opacity listed in Figure 510-119A, a wide variety of width,
landscaping point, berm, and structure combinations are possible.
These are listed in Figure 510-119B.[2] The requirements listed in Figure 510-119B pertain to the number of landscaping points, the minimum bufferyard width, and the type of berm or fencing required within every 100 feet of required bufferyard. A variety of landscaping point options are available and may be mixed within distinct portions of the same bufferyard. Section 510-115 describes the various available landscaping point alternatives. Section 510-120 provides a listing of tree and shrub species which correspond to the landscaping point descriptions.
[2]
Editor's Note: Figure 510-119B is included as an attachment to this chapter.
E.
Waiver.
Upon petition, the Plan Commission may waive the bufferyard requirements
in this section, in whole or in part, when the Commission believes
the required bufferyard will not provide the desired screening because
the adjoining properties are at significantly different elevations.
A decision of the Commission to grant a waiver must specifically state
the reason(s) for the decision.
[Added 11-15-2021 by Ord. No. 2021-12]
For the purpose of this chapter, plant materials are classified
into the following groupings: climax tree, tall deciduous tree, medium
deciduous tree, low deciduous tree, tall evergreen tree, medium evergreen
tree, low evergreen tree, tall deciduous shrub, medium deciduous shrub,
low deciduous shrub, medium evergreen shrub, low evergreen shrub,
and noncontributory plants. Species suitable for landscaping use and
compatible with local climate and soil factors are listed in Figure
510-120. The Zoning Administrator shall review proposals for and the
applicability of species not contained in this list and is authorized
to approve appropriate similar species.

A.
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 (see § 510-160), within 365 days of the issuance of an occupancy permit for any building on the subject property, unless a conditional use is approved to allow for greater than 365 days.
B.
If the subject property is to be occupied prior to the installation of all required landscaping and bufferyard material, the property owner shall sign an instrument agreeing to install the landscaping within the three-hundred-sixty-five-day period and shall furnish to the Village an irrevocable letter of credit or other form of security acceptable to the Village sufficient to guarantee completion of the work. Such security shall be provided by the property owner at the time that the agreement is signed. It shall be in an amount equal to 110% of the estimated actual cost for all of the required elements of the approved site plan and shall specifically guarantee that all such elements shall be made and installed according to the approved site plan. The costs of the work shall be furnished by the property owner and shall be verified by the Village. The financial security shall remain in force until all of the work has been completed and approved by the Village. This agreement shall also contain a statement indicating that the property owner's failure to comply with the requirements of the terms of the agreement will constitute a violation of this chapter and subject the property owner to a forfeiture upon conviction. If the required landscaping and bufferyard materials are to be installed during different phases of a subdivision development, the developer may furnish for each phase financial security in an amount sufficient to guarantee completion of the landscaping and bufferyard work performed during a particular phase, unless Chapter 495, Subdivision of Land, of the Village Code requires otherwise. If the property owner is a governmental unit, it may, in lieu of signing an agreement and furnishing a guarantee, file a resolution or letter from officers authorized to act in its behalf agreeing to comply with the provisions of this article.[1]
C.
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.
D.
All landscaping and bufferyard areas shall be seeded with lawn or
native ground cover unless such vegetation is already fully established.
E.
The exact placement of plants and structures shall be depicted on
the required detailed landscaping plan submitted to the Village for
its approval. Such plant and structure location shall be the decision
of each property owner, provided that 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 shall be located toward
the interior of the subject property and the plant material 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 adjacent property owner
agrees to provide on the immediately adjacent 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.
(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.
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. If the property owner fails to comply
with these provisions, the Village may enter upon the property for
the purpose of evaluating and maintaining all required landscaping
and bufferyard materials and may specially assess the costs thereof
against the property. A property owner's failure to comply with this
requirement shall also be considered a violation of this chapter and
shall be subject to any and all applicable enforcement procedures
and penalties.
A.
Use of required bufferyard and landscaped areas. Any and all required
bufferyards or landscaped areas may be used for passive recreation
activities. Said areas may contain pedestrian, bike or equestrian
trails, provided that no required 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.
However, in such areas, no swimming pools, tennis courts, sports fields,
golf courses, or other such similar active recreational uses shall
be permitted. No parking and no outdoor display or storage of materials
shall be permitted. Paving in such areas shall be limited to that
required for necessary access to, through, or across the subject property.[1]
B.
Utility easements. Landscaping materials, fences and berms located
within a duly recorded utility or a pedestrian easement shall not
count toward meeting a landscaping requirement, unless authorized
otherwise by a conditional use permit. However, the width of such
areas may be counted as part of a landscaping requirement.
In calculating the number of required landscaping points under
the provisions of this article, 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. Any partial plant derived from the
required calculations of this section (for example 23.3 canopy trees)
shall be rounded up to the nearest whole plant (24 canopy trees).
Any and all proposed landscaping on the subject property, required
to meet the standards of this chapter, shall be clearly depicted and
labeled as to its location and makeup on the site plan required for
the development of the subject property.
