G. Median Landscaping: The following information is to be used as general guidelines for
designing parkway medians and parking islands that are constructed with a six inch (6 ")
barrier curb. It is intended for use as a resource to develop median designs. Several
recommendations are subjective in nature and may require modification to fit median
openings, width or stopping site distances. It is important that significant deviations from
the guide be based on operational experience and objective analysis. These guidelines do
not pertain to the design of bioswales.
1. Landscape elements within a median should include shade trees, ornamental trees,
shrubs, low- growing evergreens, perennials, grasses, and groundcovers. Species
shall be primarily heat and salt tolerant.
2. Median plant heights refer to the mature plant height with the exception of all
shade and ornamental trees. Any variance from the following guidelines must be
approved by the City.
a. In the first 25 lineal feet of the median, all plant material shall be no taller
than one foot (1') at mature height and no shade or ornamental trees can
be located in this area.
b. Twenty -five to 50 feet from the intersection no plant material shall be no
taller than eighteen inches (18 ") at mature height and no shade or
ornamental trees can be located in this area.
c. Fifty to 75 lineal feet back from the intersection, plant height shall be no
taller than twenty four inches (24 ") at mature height. Shade and
7
ornamental trees may be located in this area as long as it does not affect
visibility.
d. For the remainder of the median, until 75 lineal feet from an intersection,
opening, or the end of the median, no plant height shall reach above thirty
inches (30 ") at mature height. Shade and ornamental trees can be located
in this area as long as it does not affect visibility.
e. Any plant material located within site triangles shall be no taller than
twenty four inches (24 ") at mature height. Site triangles are dependent
upon the intersection stopping site distances.
f. Shade and ornamental trees must be single stem and pruned up to a
minimum of six feet (6'). No `clump varieties' will be accepted.
g. A "clear zone" in the first one and one -half feet (1 '/2') from the curb
towards the center of the median on both sides of the median shall have no
plant material taller than one foot (1') to allow turn lanes clear visibility of
oncoming traffic.
h. Design shall be sensitive to the crown of the median. Plant material cannot
be higher than thirty -six inches (36 ") above the pavement at mature
height.
3. Tree distance to intersection:
a. No shade or ornamental tree shall be closer than fifty feet (50') to the
right -of -way of an intersection. Shade trees should be spaced one tree per
30 to 50 lineal feet and ornamental trees should be spaced one tree per 15
to 20 lineal feet, depending on the mature canopy of the species.

4. Landscape Plan of Public Landscape: A separate landscape plan shall be
submitted of the public landscape(s) for any part of the median that is to be
maintained by the City to provide clear definition for maintenance workers
between public /private properties.
5. Plant List: Plant list shall include mature height of species in addition to the
required size and height at installation.
H. Tree Preservation: The following standards shall apply to all lots which are five (5) acres
or greater in area. No live tree(s) with a four inch (4 ") DBH (diameter at breast height)
may be removed without first submitting an application for tree removal and receiving
approval from the City. Failure to apply and submit a tree preservation and removal plan
will result in a monetary fine per tree removed without authorization (as stated on the
application form.)
1. Tree Removal Permit: The application for a tree removal shall be made to the
Building Department. This application must be submitted and approved prior to
the Site Grading Plan permit issuance. If no mass grading is required for
construction, the tree removal application must be submitted and approved prior
to any site re- development involving tree removal. The application shall include:
9
i
a. Tree Preservation and Removal Plan. The plan shall include:
i. A tree survey showing the location of all trees four inches (4 ") in
caliper or greater within 100 feet of any tree proposed to be
removed, including a description of the tree(s), botanical name,
common name, caliper size and general condition or health of the
tree(s). The survey shall be completed by an International Society
of Aboriculture Certified Arborist or Illinois Department of
Natural Resources Consultant Forester, or other qualified
professional as approved in writing by the City Planner.
ii. Delineation of trees to be removed and trees to be preserved.
iii. Details and specifications or procedures to be used to protect trees
being preserved.
iv. Location, size and name of replacement trees.
b. Tree Preservation and Removal Guidelines:
i. Every reasonable effort shall be made to retain existing trees
shown on the tree survey through the integration of those trees into
the site plan and landscape plan for a proposed development.
1. Critical areas, such as floodplains, steep slopes, and
wetlands, should be left in their natural condition or only
partially cleared.
2. Roadways, storage areas, and parking lots should be
located away from valuable tree stands.
3. Cutting and filling in the vicinity of valuable trees should
be minimal.
4. If more than one -third of the tree's root system is to be
affected by construction, the tree should be part of the
removal plan and replaced with the appropriate number of
trees.
ii. Pre - construction protection measures:
1. A temporary six foot (6') orange construction safety fence,
rigid wood, or chain link fence must surround the periphery
of the tree dripline as a construction barrier prior to the start
of any site work.
10
a. Fence type may be designated by the City
depending on the value of the tree and the location
to construction traffic.
b. This fence must be in place before any site work
begins and remain in place until all construction has
been completed or final occupancy permit has been
issued, whichever is latest.
c. A warning sign shall be placed on the fence stating
the following: Warning: This fence shall not be
relocated or removed without written
authorization from the City of Yorkville.
iii. If construction limits encroach within the dripline of the tree the
following procedures will be required:
1. Trunk wrapping from the base of the tree to a height of ten
feet (10'). Clear indication of trees to be wrapped and detail
showing materials should be included as part of the
landscape plans. No boards shall be nailed to the trunk of a
tree.
2. In the event that underground utility lines are proposed
within five feet (5') of the trunk of a tree, then auguring or
boring of the utility line will be required by the City. This
must be clearly indicated on the plans.
3. Root trimming should occur by hand, not with machinery,
and exposed root systems should be protected to maintain
moisture levels. During construction, any root accidentally
damaged (exposed) should immediately be cleanly cut and
protected.
4. If excavation must occur within the dripline of a tree, an
excavation trench shall be saw cut for a minimum depth of
two feet as near to the intended trench as possible. All root
pruning must be completed prior to any excavation activity
near the tree.
iv. Construction procedures:
1. During the mass grading of the site, a Certified Arborist or
Consultant Forester must be on -site during the mass
grading to ensure that proper protection methods are being
followed.
11
2. Grading and construction equipment shall be prohibited
from encroaching within the dripline of a tree.
3. Any soil that is located or stockpiled within the critical root
zone of the tree will result in the loss of tree protection
credit(s) and will require that the job be stopped until a
revised Landscape Plan is approved.
4. Crushed limestone and other material detrimental to trees
shall not be stored or dumped within the drip line of any
tree nor at any higher location where drainage toward the
tree could conceivably affect the health of the tree.
5. Any preserved trees damaged during construction should
be repaired. Damage should be analyzed by a Certified
Arborist, Consultant Forester, or approved qualified
professional, and a repair plan should be submitted to the
City for approval.
6. If the tree begins to show signs of stress (i.e. leaf dieback,
wilting, etc.), additional measures may be required by the
City such as fertilizing or watering to aid the tree in
survival.
v. Tree Preservation protection measures must be checked by the City
of Yorkville before the permit for development will be released.
Periodic inspections will occur during construction.
i
vi. Failure to provide adequate tree protection will result in the loss of
tree protection credits and will require that the job be stopped until
a revised Landscape Plan is approved.
2. Tree Replacement Standards:
a. Any tree approved for removal shall be replaced with new trees in
accordance with the following schedule:
Caliper (Inches) of tree
to be removed Number of Replacement Trees
30 or greater 6
13 -29 5
8 -12 4

b. In the event that a tree identified to be preserved is removed or damaged,
such tree shall be replaced as follows:
12
Caliper (Inches) of tree
to be removed Number of Replacement Trees
3 0 or greater 12
13 -29 10
8 -12 8
4 -7 4
c. All replacement trees shall have a minimum caliper of two and one -half
inches (2 '/2 ") and shall consist of the shade tree varieties listed under
Permitted Plantings.
d. If the tree(s) approved for removal is (are) dead from natural causes prior
to the date of the tree removal permit, then no replacement tree(s) are
required for them.
3. Approval Criteria: The City shall approve a tree removal application if one or
more of the following conditions exist:
I
a. The tree to be removed poses a safety hazard to persons or property.
b. The tree is substantially diseased or weakened by age, storm, fire or other
injury.
c. The tree removal is in accordance with good forestry practice such as
when a parcel of land will only support a certain number of healthy trees
which is less than the number of existing trees on the parcel.
d. The tree removal is of a nuisance tree listed under Section 3 General
Standards, #7.
e. The tree removal is part of an approved overall landscape plan.
4. Failure to Replace Trees: If replacement trees, which are required by the approved
tree removal permit, are not planted within the time frame set out by the tree
removal permit, the City may, at its option, replace the trees. All costs associated
with purchasing and planting the replacement trees shall be charged to the owner
or other person or entity causing the removal of the trees.
8 -12 -3 GENERAL STANDARDS
A. Landscape Plan: Prior to receiving site plan approval, a landscape plan shall be submitted
to the City for review and approval. It is recommended that prior to submitting a site plan
or landscape plan, a pre - submittal conference be conducted to review the site plan
implications and the standards of this Chapter. The landscape plan shall contain the
following information:

3. The current zoning and land use for adjoining properties and properties located
across abutting streets.
4. The location of all freestanding signage on adjacent parcels.
5. The location, quantity, size and type (both botanical and common names) of all
existing landscaping to be preserved and removed, and all proposed landscaping
to be added. A separate document containing only the parkway tree list shall be
included as part of the landscape plan submittal.
6. The location and contours, at one foot (1') intervals, of all proposed berming and
storm water detention/retention ponds.
7. Specification of the type and boundaries of all proposed ground cover.
8. Elevation and location of all existing and proposed fences. j
9. Location of all existing and proposed utilities and easements.
10. Property line dimensions.

E. A mixture of trees is required so that a maximum of 33% of the total amount of required
trees should not be of the same genus (i.e. Acer, Malus, etc.)
14
F. Alternative Methods of Compliance: Site conditions may arise where normal compliance
is impractical or impossible or where maximum achievement of the City's objectives
can only be obtained through alternative methods.
1. Requests for alternative methods of compliance may be considered by the City for
any application to which the requirements of the Ordinance apply when one (1) or
more ofthe following conditions are present:
a. Topography, soil, vegetation or other site conditions are such that full
compliance is impossible or impractical, or improved environmental
quality would result from the alternative compliance.
b. Space limitations or the existing character surrounding neighborhood may
justify alternative compliance for infill sites and for improvements or
redevelopment in older developed areas.
c. A change of use on an existing site increases the screening required to
more than what is feasible to provide.
d. Safety considerations make alternative methods of compliance necessary.
2. Requests for alternative methods of compliance shall be accompanied by
sufficient explanation and justification, written and graphic, to allow appropriate
evaluation and decisions by the City Planner.
3. A proposed alternative compliance measure must be equal to or better than
normal compliance in terms of quality, effectiveness, durability, hardiness and
ability to meet the landscape standards of the Ordinance.
i
4. Alternative compliance shall be limited to the specific project under consideration
and shall not establish precedents for acceptance in other cases.
G. Credit for Existing Vegetation: Credit shall be given for existing trees preserved. This
does not include any species found under the nuisance tree list. Each tree that is preserved
with a caliper four inches (4 ") or larger and is listed under Permitted Plantings, shall be

Other plant material not listed may be allowed on a case -by -case basis a determined
by the City Planner.
1. Completion of Landscape Improvements: All required landscape improvements shall be
installed prior to the issuance of a certificate of occupancy. If landscape improvements
are unable to be completed due to weather conditions which, in the determination of the
19
City, are unfavorable for plant survival and growth, a temporary certificate of occupancy,
valid for no more than six (6) months, may be issued.
J. Replacements: The developer shall be responsible for replacing all required landscape
improvements that die during a period of two (2) years from the date of installation. The
City shall use the bond to replace any plant material if the developer fails to do so within
thirty (30) days of notification by the City. After the two -year period, the property owner
shall be responsible for maintaining and replacing any required plant material that dies.
K. Appeals: Any applicant may appeal any decision of the City Planner to the Zoning Board
of Appeals for recommendation to the City Council.
1. Any appeal to the standards of this chapter may be considered by the City Council
when one or more of the following conditions are present:
a. Topography, soil, vegetation or other site conditions are such that full
compliance is impossible or impractical, or improved environmental
quality would result from the alternative compliance.
b. Space limitations or the existing character surrounding neighborhood may
justify alternative compliance for infill sites and for improvements or
redevelopment in older developed areas.
C. A change of use on an existing site increases the screening required to
more than is feasible to provide.
d. Safety considerations make alternative methods of compliance necessary.
2. Requests for alternative methods of compliance shall be accompanied by
sufficient explanation and justification, written and graphic, to allow appropriate
evaluation and decisions by the City Council.
3. A proposed alternative compliance measure must be equal to or better than
normal compliance in terms of quality, effectiveness, durability, hardiness and the
ability to meet the landscape standards of the Ordinance.
4. Alternative compliance shall be limited to the specific project under consideration
and shall not establish precedents for acceptance in other cases.
