ty rn) on the
subject propershall be entitled to a credit determined by the Village Forester to offset, in
whole or in part, the any mitigation fees based on the about of Rhamnus (Buckthorn)
eliminated from the property.
21-3431. TREE REPLACEMENT PLANS:
A. When required by this Ordinance, a Tree Replacement Plan shall be submitted providing
for the planting of new trees of species, caliper and at locations approved by the Village
Forester and for a program of watering and maintenance to ensure that the new plantings
{00119256.11
Additions are bold and double -underlined; dele+:ens ai-e tr....k thy-ough.
will become established for the replacement of Protected Trees and/or Public Trees
removed or damaged by the Owner. If a Tree Replacement Plan calls for the planting
of six or more replacement trees, no more than one third of the replacement trees
shall be of a single species to prevent a Monoculture.
B. Any Owner required to make replacements for a Protected Tree shall make all such
replacements with a new tree or saplings of not less than two inches (2") caliper or eight
feet (8') in height when deciduous ornamental trees in clump form or evergreens are used
(an eight foot (8') tree is considered equivalent to a 3" caliper tree). The total aggregate
caliper of all such trees and/or saplings used as replacements based on good forestry
practices as approved by the Village Forester shall equal or exceed the DBH of the
Protected Tree(s) so removed.
C. A cash tree replacement fee shall be submitted with the Tree Replacement Plan as a
guarantee that Protected Trees will be replaced pursuant to the plan. The total fee shall be
the replacement cost per inch at breast height as established in the Village Fee ordinance
times the replacement rate specified in Section 21.4-15 of this Ordinance.
D. Replacement of Protected Trees shall be made within twelve (12) months of the date of
issuance of the Tree Removal Permit. The Village Forester upon request may grant an
extension of not more than twelve (12) months time. Upon the planting of the mitigation
trees and after the inspection and approval of the mitigation trees by the Village Forester,
the amount of cash tree replacement fee guarantee equal to the number of inches planted
will be refunded to the applicant.
21-3-526. INSPECTIONS:
A copy of the Tree Removal Permit or approved Tree Preservation Plan shall be kept at the Site
during the time that work is underway, and the Village Forester shall make whatever inspections
are required to ensure compliance. The Director is authorized to issue a stop work order for all
construction work on the Site if the Owner fails to comply with the requirements of Tree
Removal Permit or Tree Preservation Plan.
21-3631. TREE EMERGENCIES:
A. If a Tree Emergency shall occur such that there arises a risk of imminent danger or hazard
to persons or property from any Protected Tree which ought to be cut or removed
immediately or with as little delay as possible (e.g., Protected Trees which threaten to fall
or have fallen on houses or power lines or impede safe passage of streets or have become
uprooted or unstable as a result of severe weather, floods or high winds), then it shall be
lawful for the Owner to remove such Protected Tree to the extent necessary to avoid
immediate danger or hazard without a Tree Removal Permit provided that within fourteen
(14) days after taking any such action the Owner shall submit an after -the -fact Tree
{00119256.11
Additions are bold and double-underlined;-1-1-6--• ffe ,.+_....a_ 4h... ug
10
Removal Permit Application describing the Tree Emergency and the actions taken.
B. If the Village Forester upon his review of the Tree Removal Permit Application concurs
that a Tree Emergency existed and that the Owner's actions were warranted in response
to the Tree Emergency, an after -the -fact Tree Removal Permit shall be issued without fee
and no further action under these regulations shall be necessary. If the Village Forester
determines that no genuine Tree Emergency existed to justify the cutting or removal or
the Protected Tree(s), then such actions by the Owner shall be deemed a violation of these
regulations and the Owner shall be required to provide mitigation as provided in Section
21.4- 10.
21-37M. PENALTY:
Whoever violates any of the provisions of this Ordinance shall be punished by a fine of not less
than One Hundred Dollars ($100.00) and not more than One Thousand Five Hundred Dollars
($1500.00) for each such violation. A separate and distinct violation shall be deemed to have
occurred for each Protected Tree or Public Tree unlawfully damaged, removed and/or not
replaced in violation of this Article, and a separate and distinct violation shall be deemed to have
occurred for each day that such violation exists or continues. Any penalties imposed are in
addition to any required mitigation.
21-35a22. FEES:
Fees for tree removal permit applications, tree removal permits, and plan reviews shall be paid
as provided in the Village Fee Ordinance.
21-390. APPEALS:
Except as otherwise provided in this Ordinance, an applicant may appeal in writing to the Village
Manager any decision made by the Director or Village Forester within thirty (30) days of the
decision being rendered. If not satisfied with the decision of the Village Manager, the applicant
may appeal in writing to the Village Board of Trustees within thirty (30) days of the decision
rendered by the Village Manager, but the Board of Trustees is not obliged to consider any such
appeal.
21-3-841. NON LIABILITY OF VILLAGE:

VILLAGE OF DEERFIELD ADMINISTRATIVE MANUAL
I. Tree Preservation Standards
A. Purpose
The protection and preservation of trees in the Village of Deerfield will only be successful if
specific standards are implemented in order to guide the tree preservation process. The standards
will provide applicants for tree removal permits with a clear understanding of the key elements of
tree preservation. These key elements include identifying trees that are the best species, trees that
are the healthiest, and trees that can truly be saved during the construction process. Species
groups that are recognized as being suited to the Chicago region have been identified. Trees will
be evaluated for their health and form. Specific criteria have been developed to help determine
the survivability of trees in construction situations.
B. Species Groups
Appendix E contains a Species Group Guide based on the Tree and Landscape Appraisal
Council's Guide for Plant Appraisal, 10th edition. The guide is divided into three groups:
Heritage Trees, A, B, and C.
The species groups are defined as:
Heritage Trees — Any Tree, including all genera, species, varieties, cultivars, and sizes of trees,
that:
1. Represents the very best specimens of Trees, either predates or corresponds with the
incorporation of the Village in the beginning of the 20th Century, and (ill) are determined
by the Village Manager, or his or her designee, to be in good health and structurally sound;
2. Heritage Trees shall include all Trees listed below, with a DBH as indicated:
- All Oaks (quercus) with a DBH equal or greater than 25";
- All Hickory (carya) with a DBH equal or greater than 16";
- All Ironwoods (ostrya virginiana) with a DBH equal or greater than 8' ;
- All Sugar Maples (acer saccharum) with a DBH equal or greater than 20"; and
- All White Pines (pinus strobus) with a DBH equal or greater than 20".
Species Group A — Species that are best suited for the climate, soils and environmental
conditions found in northeast Illinois. These are typically slower growing, longer lived, strong
wooded and better structured species that are considered higher quality trees. This includes trees
such as bur oak, shagbark hickory, sugar maple, and hackberry.
Species Group B —Species that are of average quality in terms of wood strength, insect and
disease resistant and longevity. This includes trees such as silver maple, black walnut, and
Austrian pine.
Species Group C — Species that are of lower quality. These species may be more prone to
storm damage, insect or disease issues and/or have invasive tendencies. This includes trees
such as boxelder maple, slippery elm, and Scotch pine.
Species that are not specifically listed in the Species Groups will be evaluated by the Village
Forester and valued accordingly.
The Species Group Guide is intended to provide applicants for a tree removal permit to gain an
understanding of the general quality of the species of tree or trees that are to be removed. This is
particularly important for applicants that are proposing lot redevelopment or that are applying for
a lot improvement so that the effort can be made to preserve the best species of trees.
3
VILLAGE OF DEERFIELD ADMINISTRATIVE MANUAL
C. Inventory
All applicants for a tree removal permit, especially those proposing lot redevelopment or lot
improvement, should make special effort to preserve trees that are protected under Ordinance No.
. All applicants for a tree removal permit are required to provide information on the species, size,
condition, form, observed problems, and location of the protected tree or trees to be removed.
Appendix D includes a Tree Condition and Form Rating Guide to assist all applicants in
determining the condition and form of the trees to be included in the inventory.
For applicants who are proposing lot redevelopment or lot improvement, the inventory of public
trees and protected trees on a site is a fundamental step in assessing the opportunities for
development and tree preservation. All public trees adjacent to the subject site or that could be
impacted by the proposed construction and all protected trees on the subject property and all
protected trees on adjacent properties that are within 10' of the subject property line or whose
critical root zone extends into the subject property shall be included. All trees equal to or greater
than six inches (6") in diameter at breast height (DBH), measured at four and one-half feet (4.5')
above ground line shall be included. Data collected shall include species, size (D.B.H.),
condition, form and any observed problems and shall be listed in the Action Plan (see III below).
The protected trees shall be numbered in the field and located on the Lot redevelopment Plan.
For applicants who are applying for an ad hoc tree removal permit and that are not proposing lot
redevelopment or lot improvement the inventory shall include all public trees that are proposed
for removal and all protected trees that are proposed for removal on their property. All protected
trees equal to or greater than eight inches (8") in diameter at breast height (DBH), measured at
four and one-half feet (4.5') above ground line shall be included. Data collected shall include
species, size (D.B.H.), condition and form and shall be listed on the Permit Application Form (see
Appendix A). The protected trees shall be numbered in the field and located on a sketch of the
property that will be submitted with the application.
For applicants who are applying for a demolition permit, the inventory shall include all public
trees adjacent to the subject site and all protected trees on the subject site. Data collected shall
include species, size (D.B.H.), condition and form.
D. Tree Survey
A tree survey showing the location of all trees inventoried by tag number shall be submitted on
the lot plan with all applications for lot redevelopment, lot improvement or demolition.
E. Preservation Criteria
These criteria pertain only to applicants for a tree removal permit that are proposing lot
redevelopment or lot improvement. In order for a tree to be considered preserved, all of the
following criteria must be met:

VILLAGE OF DEERFIELD ADMINISTRATIVE MANUAL
The critical root zone (CRZ) is defined as a circle around a tree with one foot of
radius for every one inch of tree diameter at breast height (DBH).
The undisturbed critical root zone area is equal to the percentage of the area of the
critical root zone in which there is no alteration of the natural grade (including, but
not limited to, filling, excavation, trenching.)
The undisturbed circumference is equal to the distance along the critical root zone
circumference between the disturbed critical root zone areas (including, but not
limited to filling, excavation, and trenching) which intersect the circumference. The
distance shall exclude all of the disturbed area at the circumference.
hi addition, to the undisturbed critical root zone area and circumference, in order to
qualify as a preserved tree, the critical root zone must be free of any influences
outside it that may affect the health of the tree (including, but not limited to, site
drainage alteration). The developer must comply with any maintenance and
preparation requirements (including, but not limited to, watering, mulching, root
pruning, limb pruning, fertilizing, fencing, etc.) as determined by the Village at the
time of any approvals. This may include additional requirements at the time of plan
approval, if applicable. The Village shall have the right to request notification of
upcoming maintenance, as well as records detailing performed maintenance, to
confirm that maintenance is being performed properly.
Trees that meet the criteria of this section shall be considered preserved. Trees that do not
meet the criteria of this Section shall not be considered preserved and shall be mitigated.
(1) Criteria for Retention
The Village may consider a variety of criteria in determining the
individual trees that are to be retained for preservation. Preserved trees
must meet the standards listed above. In addition, the Village may
consider the condition of individual trees, tree groupings, appearance, the
overall diversity of tree species and sizes on the parcel, and the long term
viability of the trees on the site in determining the specific trees to be
retained. Final plans for tree retention shall be included in the lot
redevelopment plan approvals as appropriate.
(2) Tree Preservation Plan
Tree retention and mitigation shall be considered as part of the development
review process. A tree preservation plan shall be submitted at a scale

additional fees that are required, then the Tree Removal Permit will be
issued.
III. Tree Mitigation
The removal of healthy public trees or protected trees will require mitigation as determined by the
Village Forester.
A. Calculations
Protected trees must be mitigated by planting replacement trees on the subject site, as determined
by The Village Forester, at the rate listed below by species group (See Species Group Guide
Appendix E) for each one inch of tree diameter (D.B.H.) of public trees or protected trees
removed.
Heritage Trees must be mitigated by planting replacement trees on the subject site, as
determined by the Village Forester, at a rate of one inch of replacement tree diameter per
one inch of tree diameter of Heritage Tree removed.

Applicants proposing lot redevelopment or applying for a lot improvement will also be required
to mitigate public trees and protected trees on the site whose critical root zones are impacted to
the point where the Preservation Criteria specified above are not met. When the Lot
redevelopment Plan has been approved and/or the Lot improvement requirements have been met,
then the Village Forester will complete the applicable portions of the Permit Application Form
indicating any additional fees or mitigation requirements.
Once the applicant signs the Permit Application Form indicating acceptance of the terms of the
permit and provides any additional fees that are required, Tree Removal Permit will be issued.
B. Tree Replacement
Required replacement trees shall be shown on a Tree Replacement Plan to be submitted by the
owner to the Village. Under this plan, the owner becomes obligated to replace public trees or
protected trees for which removal is sought. The plan shall be subject to the terms and conditions
as provided under the Tree Preservation Ordinance and as agreed to on the Tree Removal Permit
Application.
For lot redevelopment and lot improvement applicants, the plan shall be at the same scale and
format as the approved lot redevelopment plan or the lot improvement plan. For applicants not
proposing lot redevelopment or applying for a lot improvement, a sketch plan will be sufficient.
Replacement species shall be selected from Species Group A and will be approved by the Village
Forester. The plan shall indicate the species, size and location of each plant to be planted. The
plan shall contain a total plant list that includes common name, botanic name, tree caliper, the
number of trees of each species, and any necessary descriptions such as balled and burlap,
container, bare root, and form.
To prevent a monoculture within the Village, tree replacement plans are encouraged to utilize various
plantings to help promote a more diverse urban forest with better longevity. If a Tree Replacement
Plan calls for the planting of six or more replacement trees, no more than one third of the replacement
trees shall be of a single species to prevent a monoculture.
The minimum size of replacement trees shall be not less than 2" caliper or eight feet (8') in height
when deciduous ornamental trees in clump form or evergreens are used, unless previously
approved by the Village Forester.
C. Fees
Fees will be as established in the annual Fee Ordinance. (See Appendix G)
A mitigation fee will be required for the replacement of healthy public trees and protected trees. This
fee will be in the form of a cash deposit in an amount that is specified in the Annual Fee Ordinance for
each one inch of healthy protected trees to be removed. The amount of this fee will be shown on the
Tree Removal Permit Application form. The fee must be provided prior to the approval of a Tree
Removal Permit. Upon the planting of the replacement trees and inspection by the Village Forester, the
amount of the cash deposit equal to the number of caliper inches of replacement trees planted times the
caliper inch amount that is specified in the annual fee ordinance for each one (1) inch of healthy
protected trees or for each one (1) inch of healthy heritage trees to be removed shall be returned to the
applicant.

VILLAGE OF DEERFIELD ADMINISTRATIVE MANUAL
D. Invasive Species Mitigation Credit
An invasive species is a non-native species (including seeds, eggs, spores, or other propagules)
whose introduction causes or is likely to cause economic harm, environmental harm, or harm to
human health. The term "invasive" is used for the most aggressive species. These species grow
and reproduce rapidly, causing major disturbance to the areas in which they are present. One
such species of an invasive plant found within the Village is the European Buckthorn. This
buckthorn invades forests, prairies, and savannas in the Midwestern United States and can form
dense thickets crowding out native shrubs and understory plants. It is difficult to remove and can
regenerate after cutting or burning.
In recognizing the many benefits of removing buckthorn, the Village will offer mitigation value
credits to property owners who properly eliminate buckthorn within the property that received the
mitigation fees. Mitigation credits will be given at a rate of 0.1" credit per one square foot of
buckthorn removed, up to one half of the total mitigation required per permit. Buckthorn to be
removed and credited must meet size requirements of twenty (20) square feet of area and must
all be at least three (3) feet tall, or as approved by the Village Forester. In order for this mitigation
credit to be applied or refunded, the permit applicant will be required to submit a letter authored
by a certified arborist stating that the required square footage of buckthorn was removed from the
property appropriately to ensure regrowth of the buckthorn does not occur. The area removed and
the method of removal and/or treatment must be specifically listed in the letter and approved by
thte Village Forester.

Appendix A. Tree Removal Permit Application and Instruction
VILLAGE OF DEERFIELD ADMINISTRATIVE MANUAL
RE: Tree Removal Permit Application
Dear Resident:
Village Ordinance requires that all residents who want to remove any trees in the Village of Deerfield
must complete a Tree Removal Permit Application.
The Applicant must completely fill in all shaded areas on the Tree Removal Information side of the Tree
Removal Application Form — Sections A and B — and return the completed form to the Village Hall.
The Village Forester will review the application and the specified trees.
• If the trees are dead, dangerous, or diseased, then a permit for their removal will be issued by
the Village. No permit fee will be paid by the Applicant.
• If the Applicant is removing trees that are not protected by Village Ordinance, then no permit
fee will be paid by the Applicant.
• If the Applicant is removing live, healthy trees that are protected by Village Ordinance
(Protected trees are all trees 8" in diameter and larger as measured 4.5 feet above the soil
line), permit fee will be required and then a permit will be issued.
Mitigation Required
All live, healthy protected trees that are removed MUST be mitigated as determined by the Village
Forester. The Village Forester will determine the number of replacement trees to be planted on the
property. The applicant is required to submit a tree replacement plan that shows the species, size (caliper)
and location of the replacement trees as specified in Ordinance 0-21-10 . If the plan is approved by the
Village Forester, then the Village Forester will complete the mitigation portion of the tree removal permit
application form. The calculation of the required replacement fee items a and b, including the listing of
the replacement trees and items a and b of the approvals section will also be completed by the Village
Forester.
Upon the completion of the plantings, the Village Forester will inspect the plantings and calculate the
amount of refund, if any, due to the applicant, and authorize the refund by completing item c of the
approvals section.
Permit Issued
Before the permit is issued, the Applicant must agree to plant the specified trees and sign Section C of the
Tree Removal Permit Application, attach the required fee, and return the completed application and fee to
the Village Hall.
Sincerely,
The Village of Deerfield

General Plan Notes
1. Prior to commencement of any construction work on this site, the protective fencing shall be installed and
reviewed by the Village Forester.
2. All work must be performed according to the approved Lot Development/Tree Preservation plan.
3. An approved Lot redevelopment/Tree Preservation Plan must be available on the building site.
4. Stay within designated work access areas shown on the plan.
5. There shall be no grading or filling within the protected critical root zones.
6. All excess fill shall be either removed from the site or stored in a location approved by the Village Forester.
7. No equipment shall be driven over or material stored on the protected critical root zones.
8. Tree fence and silt fence for all protected trees must be properly maintained throughout the construction. Tree
fence for protected trees should remain in place throughout construction.
9. All required tree protection fence and silt fencing shall remain in place until the time of finish grading and
landscaping and can only be removed upon review and approval by the Village Forester.
10. Attachments (wires, etc.) other than those approved for guying, bracing or wrapping must not be attached to
protected trees.
11. As noted in the Action Plan, all retained trees that are impacted by construction will be root pruned, crown
pruned, mulched, etc. as required. For trees which are to be preserved but which could be negatively affected
during the construction process, the crowns and roots of all such trees shall, unless otherwise determined by the
Village Forester, be pruned by a qualified arborist, according to the tree pruning standards set by ANSI Z133.1
and A300. (See also note no. 13 below.)
12. Protective fencing shall be placed to maximize the protection of the critical root zone. Protective fencing shall
be installed prior to any construction activities and shall be maintained until construction is complete. (See also
note no. 13 below.)
13. In areas where cuts are to be made for the installation of utilities or retaining walls, the adjacent tagged trees
will be root pruned. The location of the root pruning will be staked in the field and reviewed with the Village
Forester. Once the root pruning is complete, the tree protection fencing will be installed in accordance with the
tree protection plan. In some instances, it will be necessary to establish a work area that is between the edge of
the cut and the tree protection fence. The roots in this work area will be protected during the construction with
geotextile fabric placed on the existing ground and covered with 6" of wood chips. (See Root Zone Protection
detail.); or other method as approved by the Village Forester.

To Calculate Percent of Impacted Critical Root Zone:
Example:
% =
% impacted
C =
circumference = nd
A°
= angle
A =
area of circle = rlr2
Arc
= (rir A')/180
(D =
A°( ri/180)
Pi=rl=3.14
27" Red Oak 3/3 where A° = 97'
1. Calculate Al (area of entire circle):
Ai = n r2
Ai = n272
Ai = 2290.22
2. Calculate A2 (area of slice):
Az = Y2r2 x ((D - sin (D)
Az=1/2272 x (1.69 - sin 1.69)
A2 = 254.09
3. Calculate percent of impacted area:
% = A2/ Al
% = 254.09/2290.22
% =11% impacted area. (89% undisturbed)

VILLAGE OF DEERFIELD ADMINISTRATIVE MANUAL
Condition and Form Rating Guide
Condition Rating - The condition of the trees shall be based on a six (6) point scale and
one (1) being the best and six (6) being the worst.
Rating
Description
General Criteria
1
Excellent
The tree is typical of the species, has less than 10%
deadwood in the crown that is attributable to normal
causes, has no other observed problems, and required
no remedial action.
2
Good to Fair
The tree is typical of the species and/or has less than
20% deadwood in the crown, only one or two minor
problems that are easily corrected with normal care.
3
Fair
The tree is typical of the species and/or has less than
30% deadwood in the crown, one or two minor
problems that are not eminently lethal to the tree, and
no significant decay or structural problems, but the
tree must have remedial care above normal care in
order to minimize the impact of future stress and to
insure continued health.
4
Fair to Poor
The tree is not typical of the species and/or has
significant problems such as 30-50% deadwood in
the crown, serious decay or structural defect, insects,
disease or other problems that can be eminently
lethal to the tree or create a hazardous tree if not
corrected in a short period of time of if the tree is
subjected to additional stress.
5
Poor
The tree is not typical of the species and/or has over
50% deadwood in the crown, major decay or
structural problems, is hazardous or is severely
involved with insects, disease, or other problems that
even if aggressively corrected would not result in the
long term survival of the tree.
6
Dead
Less than 10% of the tree shows signs of life.
Form Rating — Subjective evaluation comparing tree with specimen tree of the same species.
Form classes are the same as those listed above under condition, with the exception of number 6,
which translates to `very poor form'. Typical form defects might include multiple leaders, no
leader, lean, one sided crown, trunk crook, etc.
Mitigate conditions 1, 2, & 3 trees, but not conditions 4, 5 & 6 trees. The assignment of the
condition and form ratings to specific trees are subject to the Village Forester's review.
