accomplishes the following objectives:
~4~
Page 4 of 17 Doc ID: bdf3a2dc829e3f0c9aae27f9f2805095f2ff020d
50-O-23
1. Stabilize valuable topsoil by preventing or minimizing unnecessary soil erosion and
sedimentation;
2. Assist in proper stormwater runoff in order to decrease the costs associated with flooding;

of water and the neutralization of wastes that pass through to the groundwater table and other
aquifers;
4. Aid in the reduction of air pollution through the removal of harmful carbon dioxide and the
generation of oxygen;
5. Provide a buffer and screen against noise pollution;
6. Provide a haven and nesting areas for birds, insects, and other forms of wildlife that are
essential to the maintenance of the food chain and that help control and eliminate disease-
carrying mosquitoes;
7. Reduce energy consumption through the windbreak and shade effects of trees;
8. Protect and increase property values in a manner that maintains each property owner's
enjoyment of his or her property;
9. Conserve and enhance the City's physical and aesthetic environment;
10. Eliminate trees that constitute a threat, danger, or nuisance to the public or to property in
the City, or that may be dangerous to the health of other trees and vegetation in the City;
11. Protect and enhance the quality of life and the general welfare of the City and its
residents; and
12. Restore, to the greatest extent possible, denuded soil that results from construction and
grading work accompanying development.
SECTION 7: Section 7-8-8-7, “Tree Replacement,” of the Evanston City Code of
2012, as amended, is hereby amended as follows:
7-8-8-7. - TREE REPLACEMENT.
A. General requirements. Any protected tree damaged or removed in the course of a
regulated activity must be replaced by the applicant pursuant to this Section and as depicted
in a tree replacement plan pursuant to Subsection 7-8-8-7.I of this Section, regardless of
whether the protected tree is located on the same lot on which the regulated activity takes
place; except, that the City Manager or his/her designee may, pursuant to Subsection G of
this Section, consider a request to submit a fee in lieu of the replacement of trees, and except
for the exemptions in Subsection B of this Section. No replacement tree may have a caliper
less than two and one-half (2½) inches.
~5~
Page 5 of 17 Doc ID: bdf3a2dc829e3f0c9aae27f9f2805095f2ff020d
50-O-23
B. Exemptions. Tree replacement will not be required if the City Manager or his/her designee
determines that any of the following circumstances exist:
1. When a protected tree, due to natural causes, is dead, dangerous, or interferes with any
existing or proposed public improvements, is in dangerous proximity to any public utility lines
or related facilities, or is a diseased tree or dangerous tree or otherwise unsafe, unhealthy, or
insect infested and constitutes a hazard to persons, property, or other trees.
2. When a protected tree, due to natural causes, obstructs any street, sidewalk, or any
pedestrian path to an extent that the protected tree interferes with free passage and clear
view along the street, sidewalk or path, and at any street, alley or driveway intersection.
3. When removal of a protected tree is necessary to comply with the current standards
generally observed by professionals in the forestry profession.
4. When the removal involves only the removal of class D trees or exotic and invasive
species and does not involve any protected tree.
5. When the protected tree to be removed is located within the foundation footprint of an
addition which creates additional gross floor area for an existing structure; provided, that the
combined gross floor area for the existing structure and the addition is compliant with the
maximum gross floor area restrictions for the structure under this Code and that the addition
does not require any variations. In this event, replacement trees will be required only for fifty
(50) percent of the removed protected trees within the construction footprint, at the
replacement rate set forth in Subsection C of this Section.
6. When the protected tree to be removed is located within the foundation footprint of an
addition which creates additional gross floor area for a structure designated as a landmark
pursuant to this Code; provided, that the combined gross floor area for the existing structure
and the addition is compliant with the maximum gross floor area restrictions for the structure
under this Code, that the addition does not require any variations, and that the City Historic
Preservation Commission has conducted an advisory review pursuant to this Code and
determined that the addition is consistent with the purposes and goals of the City Historic
Preservation Commission regulations. In this event, replacement trees will not be required for
the removed protected trees within the construction footprint.
7. When the removal of a protected tree is due to a pre-existing conflict with existing
underground utilities and obstructs the repair or replacement of those utility services, and
there is no reasonable alternative method to re-route the utility line to avoid removal of the
tree.
C. Replacement formula. Protected trees must be replaced by group A trees pursuant to the
replacement rate specified in this Subsection. The tree replacement rate is determined by the
species of tree removed. For each inch of dbh removed, replacement trees must be provided
at the rate shown in the following table. For example, for every inch in diameter of a removed
~6~
Page 6 of 17 Doc ID: bdf3a2dc829e3f0c9aae27f9f2805095f2ff020d
50-O-23
group A tree, each inch removed must be replaced with one and one-quarter (1.25) inches in
diameter of replacement trees:
Species Removed
Diameter Of
Tree
Removed
Replacement
Rate
All public trees 1 inch 125 percent
Group A 1 inch 125 percent
Group B 1 inch 75 percent
Group C 1 inch 50 percent
D. Specifications. All replacement trees must be:
1. Provided by the applicant at the replacement rate specified in Subsection C of this Section;
2. Of a species listed in group A set forth in Appendix A, Subsection 7-8-8-13 of this Section;
3. At least two and one-half (2½) caliper inches;
4. Grown within the northeast Illinois region or within a seventy-five-mile radius of Evanston;
5. In conformance with the nursery stock standards; provided, however, that in the event that
the implementation or enforcement of the nursery stock standards conflicts with the
implementation or enforcement of the tree care standards, the provisions of the tree care
standards will control;
6. Pursuant to a written time schedule approved by the City Manager or his/her designee;
7. Planted in a location approved in advance by the City Manager or his/her designee; and
8. Inspected by the City Manager or his/her designee prior to planting.
E. Care of replacement trees. The applicant will be solely responsible for the care and
feeding of newly planted trees for a period of two (2) years, which time shall commence upon
the issuance of a final certificate of occupancy for the property as required pursuant to the
City building regulations or, if no final certificate of occupancy is required, upon completion of
the tree replacement plan as determined by the City Manager or his/her designee pursuant to
Subsection I of this Section. The care and feeding of newly planted trees must, at a minimum,
adhere to the tree care standards.
F. Alternative locations. The City Manager or his/her designee may reduce the number of
replacement trees to be planted on the subject property and designate alternative locations
for new trees on the subject property upon determining that full tree replacement will result in
unreasonable crowding of trees or would be otherwise inconsistent with current standards
generally observed by forestry professionals. If the City Manager or his/her designee cannot
~7~
Page 7 of 17 Doc ID: bdf3a2dc829e3f0c9aae27f9f2805095f2ff020d
50-O-23
identify an appropriate alternative location on the subject property for a tree, that tree may be
replaced by a fee in lieu of replacement pursuant to Subsection G of this Section.
G. Fee in lieu of replacement.
1. Modification of tree replacement requirement. The City Manager or his/her designee may
permit the applicant to pay a fee in lieu of any portion of the tree replacement requirements if
the City Manager or his/her designee determines that replacing trees at the full replacement
rate provided by Subsection 7-8-8-7.C of this Section would:
a. Result in the unreasonable crowding of trees upon the subject property or upon a public
right-of-way immediately adjacent to the subject property; or
b. Adversely impact the viability of existing trees on the subject property; or
c. Not be consistent with the current standards generally observed by professionals in the
forestry profession.
2. Calculation of fee. Upon a determination by the City Manager or his/her designee that an
applicant has demonstrated one (1) or more of the above, in lieu of providing replacement
trees at the required replacement rate, the tree replacement plan will be modified to require
the applicant to: a) replace the tree(s) at the replacement rate in Subsection 7-8-8-7.C of this
Section; and b) pay a tree replacement mitigation fee of one hundred fifty dollars ($150.00)
per caliper inch diameter inch using the mitigation formula: (DBH removed tree x coefficient x
cost of planting one replacement tree) / (caliper inch of replacement trees) = mitigation fee in
lieu of number of replacement trees. The most current tree replacement practices and rates
(such as standard caliper inch of replacement trees and cost of planting one replacement tree)
shall be publicly available in the City’s Tree Canopy Preservation Policy. This mitigation fee
represents the value of trees as a resource that provides benefits to the ecosystem and to
Evanston as a community. All tree replacement mitigation fees collected by the City will be
used to promote the purposes of planting managing and maintaining a healthy urban tree
canopy trees in the City.
H. Waiver or modification of provisions. Where a previous zoning or subdivision approval
contains conditions which fully accomplish the goals and purposes of this Section, the City
council may waive or modify the requirements of this Section. The waiver or modification may
be revoked at any time that any condition imposed pursuant to the approval is violated.
I. Tree replacement plan.
1. Required. A tree replacement plan must be filed with all tree permit applications for a
regulated activity involving the replacement of one (1) or more protected trees.
2. Contents of plan. A tree replacement plan must contain the following information:
a. A brief description of the applicant's plan for the replacement of protected trees in
accordance with the requirements in this Section. The description must specifically include,
~8~
Page 8 of 17 Doc ID: bdf3a2dc829e3f0c9aae27f9f2805095f2ff020d
50-O-23
without limitation, the replacement and planting methods and technologies that the applicant
intends to employ in order to satisfy the requirements of this Section.
b. The number, size, species, and proposed location of the trees that the applicant is
required to plant or replant, if any, pursuant to the requirements of this Section.
c. Other data and information as the City Manager or his/her designee deems necessary in
order to comply with the requirements of this Section, as set forth in the administrative manual.
3. Inspection; compliance with plan. Upon notification from the applicant that the
requirements of the tree replacement plan have been completed, the City Manager or his/her
designee will inspect the property to determine compliance with the tree replacement plan. No
final certificate of occupancy may be issued for the property until the City Manager or his/her
designee approves of the implementation of the tree replacement plan.
J. Security requirements.
1. Security required. Every tree replacement plan must be accompanied by a tree
replacement security, except as modified or waived by the City Manager or his/her designee
pursuant to Subsection J.5 of this Section. The tree replacement security must consist of:
a. A cash deposit to be held in escrow by the City;
b. An irrevocable letter of credit issued by a lender authorized to issue the letter by any state
or by the United States;
c. A bond with good and sufficient surety; or
d. Another form of security approved by the City Manager.
2. Amount. The amount of the tree replacement security will be determined by the City
Manager or his/her designee and must be equal to three (3) times the total actual cost of
strictly complying with and fully implementing the tree replacement plan, with any applicable
adjustment for cost of living increases and/or inflation.
3. Replenishment of security. If, at any time, the City Manager or his/her designee
determines that the funds remaining in the tree replacement security are not or may not be
sufficient to pay, in full, the total actual costs of strictly complying with and fully implementing
the tree replacement plan, then, within ten (10) days following a demand by the City, the
applicant must increase the amount of the tree replacement security to an amount determined
by the City Manager or his/her designee to be sufficient to pay the uncovered costs. Failure to
so increase the amount of the tree replacement security will be grounds for the City to retain
or draw down any remaining balance of the tree replacement security.
4. Return of security. Upon completion of the tree replacement plan pursuant to Subsection
I.3 of this Section, the tree replacement security, or any remainder thereof, will be returned or
released to the applicant.
~9~

50-O-23
5. Limited waiver. Where a tree permit application concerns the damage or removal of trees
unrelated to construction activity, the City Manager or his/her designee may, modify or waive
the requirement for submittal of the tree replacement security if the City Manager or his/her
designee determines that the tree replacement security is not necessary for the limited
damage or removal and that the purposes of this Section will be fulfilled without submittal of
the tree replacement security.
K. Failure to comply.
1. Notice. If, at any time, the City Manager or his/her designee determines that the applicant
has failed to comply with or implement the tree replacement plan, the City Manager or his/her
designee will cause notice of the failure to be served upon the applicant and will order the
applicant to fully comply with the tree replacement plan within fourteen (14) days following
mailing or personal delivery of the notice. The notice must be personally served or sent by
certified mail, return receipt requested, to the applicant and must notify the applicant that,
absent an appeal pursuant to Subsection K.3 of this Section, unless full compliance with the
tree replacement plan is achieved within fourteen (14) days from the date of mailing or
personal delivery of the notice, the City may proceed to perform or cause to be performed
work the City Manager or his/her designee determines necessary to achieve full compliance
with the tree replacement plan.
2. Opportunity to comply. Absent an appeal pursuant to Subsection K.3 of this Section, within
thirty (30) days following mailing or personal delivery of the required notice, the applicant
must take action as is necessary to strictly comply with and implement the tree replacement
plan.
3. Appeal. Within fourteen (14) days following personal delivery or mailing of the required
notice, the applicant may appeal the City Manager or his/her designee's determination by
filing a written notice of appeal with the City Manager. The filing of an appeal will toll the thirty-
day period in which the applicant is required to take action pursuant to Subsection K.2 of this
Section from the date on which the City Manager receives the applicant's notice of appeal.
Upon receipt of a notice of appeal, the City Manager will review all reliable and relevant
documents and information pertaining to the City Manager or his/her designee's determination.
The City Manager must render a written decision on the appeal no later than fourteen (14)
days after the City Manager receives the written notice of appeal. The City Manager must
notify the applicant of the City Manager's decision within two (2) days after the decision and
must provide the applicant a copy of the decision. The action taken by the City Manager will
be final. The tolling of the thirty-day period will cease upon the applicant's receipt or notice of
the City Manager's decision.
4. City right to complete work. If the applicant neglects or refuses to fully comply with and
implement the tree replacement plan within the thirty-day period during planting season
pursuant to this Subsection, then the City Manager or his/her designee, with the consent of
~10~
Page 10 of 17 Doc ID: bdf3a2dc829e3f0c9aae27f9f2805095f2ff020d
50-O-23
the City Manager, and, if applicable, upon the denial of any applicable appeal, will be
authorized to perform or to cause to be performed work necessary to ensure strict compliance
with and full implementation of the tree replacement plan. The City Manager or his/her
designee will have the right to deduct, liquidate, draw down, or apply an amount equivalent to
three (3) times the actual costs of the work from the tree replacement security, as well as to
exercise all other rights and remedies available to the City, including, without limitation, any
applicable lien rights.

SECTION 9: Section 7-8-8-13, “Appendix A, Species Rating Guide,” of the
Evanston City Code of 2012, as amended, is hereby amended as follows:
7-8-8-13. - APPENDIX A, SPECIES RATING GUIDE TREE CANOPY PRESERVATION
POLICY
The Tree Canopy Preservation Policy will be made available for inspection on the City’s
website and in physical form at the City Clerk’s offices. This policy will include the city’s most
current policies and practices according to such standards as best arboricultural practices,
permit application requirements and procedures, fee and penalty schedules, and other urban
forest management practices as applicable. The Policy shall include, without limitation:
A. The intent of this guide is to identify tTree species groupings according to environmental
and ecosystem value and contribution; by genetic quality and community value; survivability
in the City’s climate; and to assign them to a species group based on these and other
applicable two (2) criteria. The species groups are noted as A, B, C, and D. Species group A
is the most highly rated group. Species group D is the lowest rated group and includes the
tree species that are not protected in this Section. The species rating guide is the basis for
assessing the relative value of trees to be protected and mitigated if they are damaged or
removed.
B. Most current rates for tree replacement and mitigation;
