Page 2 of 4
development process and the current status. Commissioners agreed to review the current draft comments for discussion starting at the beginning of the document.
Commissioner Husbands suggested that the current purpose statement be revised.
Husbands read the Purpose statement from the City of Minnetonka’s tree ordinance and suggested that some of the content be incorporated in this draft. Staff proposed
sending suggested changes or additions to the purpose section to staff, and staff would then send out to the Commission over email for review.
Commissioner Stein suggested adding an applicability section at the beginning of the
ordinance.
Coordinator Spreiter then brought the definition of clear cutting to the group as a discussion item continued from the last work session. The Commission discussed how
it would fit into the ordinance and how it would apply in the City.
Commissioner Husbands read a definition of ‘tree removal’ from the City of Minnetonka’s ordinance. The definition included damaging trees to cause death. The
Commission also discussed using a percentage of trees removed as a definition of clear cutting or significant removal.
The Commission discussed cases in which lots are clearcut or tree removal is done and
the owner is not currently developing, re-developing, grading, or otherwise doing work
that would require a permit. What would be considered clearcutting was also
discussed.
Commissioner Knosalla suggested adding additional language into the applicability or requirements for developing a forest management plan, that would include tree
removal on vacant lots. Commissioner Knosalla brought the subject of adding enforcement for clearcutting into the ordinance to the group. She suggested adding a
minimum % of tree removal into applicability for permit and management plan requirements, instead of adding clearcutting as a definition.
The Commission discussed further protections that could be included for Specimen
Trees. The Commission discussed protections that could be added for Heritage Trees.
Commissioner McCaslin suggested developing an education program for Heritage
Trees.
A suggestion was made to change the term ‘Specimen Tree’ to ‘Heritage Trees’.
Commissioner Knosalla suggested adding a stipulation for removing any Heritage Tree,
in which a permit would be required.

Page 3 of 4
Percentage of trees removed was discussed further, in determining when a permit or plan is needed. The Commission came to a consensus that removal of 50% or more of
trees on any lot would require a permit and Forest Management Plan.
The definition of Critical Root Zone was discussed. Commissioner Husbands read an example of a definition of Critical Root Zone. She offered to send the language to Staff
for inclusion.
Commissioner Husbands suggested adding a definition of tree removal to included tree damage that would cause death.
The definition of Vacant Lot was also discussed.
Commissioner Knosalla’s comment of removing the term Wood Lot, as it is not used
anywhere else in the ordinance.
Commissioner suggested adding a definition for Major Home Addition. Major Home Addition was discussed further in applicability throughout the current draft of the
ordinance.
Applicability and requirements for a Forest Management Plan and Forest Alteration Permit were discussed. The addition of permits for accessory structures was discussed.
The Commission discussed the definition and criteria for Heritage Trees. The
Commission decided to lower the diameter minimum to 24 inches to qualify as a
Heritage Tree. Height was discussed as a criteria for conifers.
A definition and addition of ‘Minor Home Additions’ was suggested. Tree protection
requirements were discussed. Requirements for tree replacement were discussed. The
requirement for escrows and maintenance were also discussed. Commissioner Knosalla
suggested adding a requirement for tree replacement within the first three years after
planting should be added.
When a permit would be required for Heritage Tree removal. The definition of Hazard
Tree’ was discussed, versus trees that pose a safety concern. Striking the sentence that
deemed removal of Heritage Trees prohibited was decided. Further discussion of how
to protect Heritage Trees ensued. It was decided that a permit would be required, but a
Forest Management Plan would not be required for removal of Heritage Trees alone,
when not part of a larger project that would require another permit.

FROM: Krista Spreiter, Natural Resources Coordinator
SUBJECT: Proposed Residential and Commercial Shade Tree Program
Background
The proposal of a residential and/or commercial shade tree program has been requested to be
brought to the Commission for discussion, using the City of St. Louis Park shade tree program as
an example. Staff has contacted the City of St. Louis Park as well as Tree Trust, to acquire
information on cost and details for what the program may entail. Currently the City of St. Louis
Park provides trees to its residents and businesses through the following services:
•Spring and fall annual self-service tree sales (this is similar to what Mendota Heights
currently provides).
•Full-service tree sale and planting program: Assistance with transport and planting
available to residential property owners at a reduced cost. Additional discounts given to
properties located in an Environmental Justice priority area, as well as properties that
recently lost an ash tree due to EAB.
•Commercial and nonprofit property owner cost share program: Commercial and
nonprofit companies may hire any vendor to plant up to three trees on their property and
the city shares in the cost (base rate of 30% up to $200/tree). Additional subsidies given
to properties located in an Environmental Justice priority area and properties that
recently lost an ash tree due to EAB.
Tree Trust was contacted and shared the following estimated costs for providing trees, tree
planting and care:
•#10 container tree, including transportation and planting services = $300/tree
•Tree watering = $150/hour
Requested Action
Information only. The Commission in invited to discuss the potential for a residential and/or
commercial shade tree program and provide any feedback.

SUBJECT: Demonstration Hybrid Tree Planting Update
Background
As part of Goal 3, Urban Forestry Awareness and Opportunities, the Goal 3 Committee has worked
to plan for and create a demonstration hybrid tree planting project in Marie Park. The project
entails the restoration of an un-mowed area within Marie Park that had been taken over by
invasive species.
Quotes for restoration were solicited in August of 2023, and Landbridge Ecological was chosen
as a consultant in September. The project site was treated with herbicide, and a prescribed burn
was carried out to prepare the site for planting. A custom native grass seed mix was then planted
as a dormant seeding in late October. The project will resume in the spring of 2024, with planting
of chosen shade trees, both overstory and understory, as well as pollinator shrub and forb
plantings. The project also includes providing for public educational opportunities once the
planting is complete.

URBAN FOREST MANAGEMENT
SECTION:
X-X-1: PURPOSE AND BENEFITS
X-X-2: DEFINITIONS
X-X-3: STANDARDS
X-X-4: FOREST ALTERATION
X-X-5: FOREST MANAGEMENT PLAN
X-X-6: TREE MITIGATION
X-X-7: DISEASED TREES
X-X-8: ENFORCEMENT
X-X-1: PURPOSE.
Trees and woodlands play an integral role throughout the City of Mendota Heights, providing improved
air quality, erosion control, energy conservation, wildlife habitat, cooler surface temperatures, increased
property values, and aesthetic beauty. It is therefore the intent of the City of Mendota Heights to
protect, preserve, and enhance trees and woodlands within the City, and to encourage a resourceful and
prudent approach to development and redevelopment within the city, thereby promoting and
protecting public health, safety, welfare and assuring a healthy urban forest into the future.
X-X-2 APPLICABILITY.
This ordinance applies to construction projects that involve development and redevelopment. The
ordinance also applies to any property at which 50% or more significant and/or heritage trees are
removed from the property.
X-X-2: DEFINITIONS.
The following words, terms and phrases, as used in this division, shall have the meanings ascribed to
them in this section:
American National Standards Institute (ANSI) A300 Tree standards means standards set forth by the
ANSI in Standard A300 that set forth performance standards for the care and maintenance of trees,
shrubs, and other woody plants. ANSI A300 Part 6 standards addresses planting and transplanting of
trees, shrubs, and woody plants, as well as post-planting care. These standards do not replace or
supersede city ordinances.
Applicant means developer, builder, contractor, or owner who applies for a forest alteration, land use,
grading, or building permit.
Commented [RH1]: Name should be changed to Tree
Ordinance or Tree Preservation Ordinance and not Urban
Forest Management Ordinance. More precise language
Commented [RH2]: Applicability: The provisions of this
ordinance apply whenever construction, site work,
development, or redevelopment activities occur on a
property. (MTKA)
Commented [RH3]: Propose adding the following to our
Purpose statement: The purpose of this ordinance is to
encourage tree preservation by reasonably limiting the
removal of trees during construction, site work and land
development activities, as well as to mitigate for the loss of
trees due to these activities while maintaining the rights of
existing homeowners to use their private property. (MTKA)
Include: mature trees and groups of trees add to property
value and contribute to the identity of the city.
Commented [SW(4]: Note: Major home additions are
not regulated separately but rather are covered by this 50%
rule. This is generally consistent with the direction
discussed at the 1st work session but it does bring in some
protections for all properties.
14 7b1.
Caliper inch means a measurement used for nursery stock and in this chapter refers to replacement
trees. It is the unit of measurement for defining the diameter of the tree trunk measured six inches
above the soil surface for tree trunks four diameter inches or less and measured 12 inches above the
soil surface for tree trunks greater than four diameter inches.
Certified arborist means an arborist with up-to-date certification by the International Society of
Arborists (ISA).
Conifer tree means a woody plant that is a member of the division Pinophyta and at maturity is at
least 12 feet or more in height. Conifers are cone bearing and most in our climate keep their leaves
(also called needles) year-round. Tamarack (also called larch) is the only native conifer in our climate
that drops all of its needles in the fall.
Control includes measures to prevent, slow the spread, suppress, eradicate, or destroy a tree disease
or pests.
Critical Root Zone (CRZ) means the minimum area around a tree that must remain undisturbed. The
critical root radius is calculated by measuring the tree's diameter at standard height (DSH). For each inch
of tree diameter, 1.5 feet of root zone radius must be protected. For example, if a tree's DSH is 10
inches, then its critical root zone radius is 15 feet (10 x 1.5 = 15).
Deciduous tree means a woody plant, which sheds leaves annually, having a defined crown and at
maturity is at least 15 feet or more in height.
Development means a project on land, including vacant land, which the construction of structures,
improvements, or land use changes has been approved by the City.
Diameter at Standard Height (DSH) is a measurement used for trees in the landscape. It is the
diameter of a tree trunk as measured at a height of four and one-half feet above ground. To
determine diameter, measure the circumference of the tree trunk at four and one-half feet above
ground and divide by 3.14.
Forest is a stand of significant trees covering at least a quarter acre of ground, where the leaves and
branches of trees (forest canopy) shade 75 percent or more of the ground. Forests can be continuous
areas covering many acres or can be isolated quarter-acre patches on individual or multiple lots.
Forest management plan is a plan that shows all trees located within the area to be developed or
within the property. The plan shall include all significant and specimen trees to be preserved and
measures taken to preserve them. The plan will also include calculations to determine the number of
replacement trees as required by the tree removal, mitigation, and replacement section of this
division and a proposed reforestation landscape plan. The plan shall be developed by a forestry or
horticultural professional.
Heritage tree means a tree of any native species or cultivar of a native species that is 24 inches in
diameter or greater, except invasive species. Heritage trees are healthy trees that are likely to have a
life expectancy of greater than ten years, have a relatively sound and solid trunk with no extensive
Commented [KS5]: Caliper inch is the standard
measurement used in measuring nursery stock (as well as
container size and height). Therefore, this would be the
measurement used when requiring replacement trees, but
not used when referring to significant and heritage trees.
DSH/DBH is not used in nursery stock measurement, rather
to measure existing/planted/mature trees.
Commented [RH6]: And significant and heritage trees
too?
Commented [HS7]: That requires a permit from the city.
Commented [RH8]: Should we put the definitions of the
following in this area:
Woodland preservation area
Floodplain Forest
Lowland Hardwood Forest
Maple Basswood Forest
Mesic Oak Forest
Oak Woodland Brushland
Tamarack Swamp
Willow Swamp
All are defined in the NRMP and in the MTKA Tree
ordinance.
Commented [SW(9]: I prefer retaining this phrase.
Native trees have a higher ecological value and that should
be reflected in what we are trying to preserve and in how
we replace. Could add reference to Minnesota Department
of Natural Resources’ Best Native Yard Trees for our
Changing Climate (state.mn.us), if desired to capture trees
that are adapting and becoming native to this area.
15
decay or hollow, and have no major insects, pathological problem, or defects and is not deemed a
Hazard Tree. Heritage trees are valued for their size and their legacy.
Hazard tree means a tree that has structural defects that may cause the tree or tree part to fail, and
has been determined that such failure could cause property damage or personal injury and has been
identified as a hazard tree or high risk tree by an ISA Certified Arborist.
Invasive species means species that are not native to Minnesota and cause economic or
environmental harm or harm to human health.
Major home additions means a project…
Native tree means a tree native to the local ecosystem(s) found in Mendota Heights and immediate
surrounding area, is naturally found in the area, is suited to the local climatological conditions, and is
not an introduced, exotic, noxious, or invasive species.
Natural Resources Coordinator means a natural resources professional who is employed by the city or
appropriate agent or independent contractor designated by the city administrator.
Redevelopment means a project in which the construction of structures, improvements, or land use
changes has been approved by the City. Lots with existing structures that are split for the construction
of additional structures are included in this definition. (Will Stein)
Shade tree means a woody perennial that at maturity is at least 15 feet in height and grown primarily
for aesthetic or environmental purposes.
Significant tree means a healthy tree measuring a minimum of six inches in diameter for deciduous
trees, 10 feet in height for conifer trees, and is not considered hazardous. Buckthorn or other noxious,
invasive, woody plants or trees as determined by the Natural Resources Coordinator are not
considered a significant tree species at any diameter.
Structure means anything manufactured, constructed, or erected which is normally attached to or
positioned on land, including portable structures.
Tree Pest means any vertebrate or invertebrate animal, plant pathogen, or plant that is determined by
the City to be harmful, injurious, or destructive to trees or community forests.
Tree Removal means
Utility means electric, telephone, cable television, water, sanitary or storm sewer, solid waste, gas or
similar service operations.
Commented [RH11]: Could we say “home addition
requiring work on the outside of the house that would
disturb tree cover” As opposed to defining Major?
Commented [HS10]: In historic preservation, a major
home alteration means any exterior alteration that affects
10% or more of the home. Is that a possible path here?
Commented [KS12]: Lori Knosalla: Should only apply
when trees are being removed
Commented [SW(13]: Recommend deleting ‘major home
addition’ and cover all properties by the 50% provision.
Commented [HS14]: That requires a permit.
Commented [RH15]: Definition of removal/removed is
the physical removal of a tree or 1. Girdling;, 2. Injury;, 3.
Pruning of 30% or more of the crown; 4. Trimming an oak
between April 1 and July 15; or 5. compacting, cutting, filling
or paving 30% of the critical root zone for all tree species.
(MTKA)
A healthy protected tree that did not pose a significant or
severe risk to personal safety or property damage and that
was removed or otherwise destroyed by unnatural causes
within three years before a redevelopment or subdivision
application will be regarded as if it were present at the time
of construction or a development application. In no case
may healthy protected trees be removed from properties
required to have a tree preservation or landscape plan
unless first approved by the city. (MTKA)
Commented [SW(16]: I think this is clear without a
formal definition.
16
Vacant Lot means a lot or parcel located within the city that is not currently occupied by a resident,
business, or organization.
X-X-3: STANDARDS.
American National Standards Institute (ANSI) A300 shall be followed in the planting, transplanting,
and care of trees and other woody species. The Natural Resources Coordinator shall have the
authority to develop additional tree standards concerning the management of trees when necessary.
These standards shall not contradict this chapter.
X-X-4: FOREST ALTERATION PERMIT.
A.Forest alteration permit. A forest alteration permit application is required to be submitted to
the City’s Natural Resources Coordinator for review prior to removing any significant or
heritage trees as part of any of the following:
•Development or redevelopment project
•A grading permit
•Lot-split or other land use alteration
•When removing 50% of Significant and/or Heritage trees on any lot, vacant or
otherwise occupied.
•Removal of any Heritage tree.
Failure to obtain an approved Forest Alteration Permit application prior to removing significant or
specimen trees will result in a tree replacement requirement that assumes all trees removed were
significant trees, and/or escrow fee forfeiture.
B.Any significant and heritage trees removed as part of a forest alteration permit shall follow
requirements for tree replacement as shown in X-X-6: Tree Mitigation.
C.Forest alteration permit appeal process. If the forest alteration permit is denied by the Natural
Resources Coordinator, the applicant may appeal the decision. The appeal shall be submitted
in writing, along the argument(s) for appeal, and received by the City within 15 days of denial.
The City Council will review the appeal at its next available City Council meeting for final
decision of the appeal.
X-X-5: FOREST MANAGEMENT PLAN REQUIRED.
The applicant shall submit a forest management plan containing all requirements listed in X-X-
5, and other necessary information to determine compliance with this chapter, when
removing any significant or heritage trees as part of any of the following:
•Development or redevelopment project
•As part of a grading permit
•A major home addition (Will Stein)
•Lot-split or other land use alteration
•When removing 50% or more of significant and/or heritage trees on any lot, vacant or
otherwise occupied
Commented [HS17]: This means that a parcel with an
empty structure on it would be considered a vacant lot. I
don't think that is correct. I would say "not currently
occupied by a building, structure, or object." Whether or
not the building, structure, or object is occupied is
immaterial.
Commented [SW(18]: I separated these because the
bulleted cases apply to the removal of any significant or
heritage trees.
Commented [KS19]: I DO NOT FEEL THAT CONSENSUS
HAS BEEN REACHED ON THIS. Is it ANY Heritage Tree, or
more than one? Are there exemptions? Ex. Proximity to
structures, safety concerns, etc.
Commented [RH20R19]: Could we have a process
described for review if there needs to be a variance to this
statement?
17
An application fee, as well as escrow fee, shall be required as established annually be the City
Council. The forest management plan should reflect the applicant's best effort to determine the
most feasible and practical layout of buildings, parking lots, driveways, streets, storage and
recreational facilities, and other physical features, so as to remove or damage the fewest
significant and/or heritage trees and minimize the negative environmental effects caused by loss
of tree canopy.
A.Forest Management Plan Requirements
1.The forest management plan shall include the following:
a. A forest and significant tree inventory overlaid on site plans that shows size, species,
general health, and location of all significant trees located within the property where
tree removal is proposed.
b. A list of total diameter inches of all healthy significant and heritage trees inventoried.
c. A list of the total diameter inches of healthy significant and heritage trees proposed
for removal.
d. Location of trees preserved and the proposed measures for protection, including
delineation of tree protection fencing, tree protection signs, location for material
storage, parking, debris storage, and wash-out area for cement trucks.
e. Protection measures for replacement trees being planted in areas with high deer
population.
f. The name(s), telephone number(s), and address(es) of the person(s) responsible for
tree preservation during the course of the development project.
g. Size, species, number, and location of all replacement trees and woody shrubs
proposed to be planted on the property in accordance with E. Significant and Heritage
Tree Replacement Calculation and X.X.6 Tree Mitigation.
h. The outer boundaries shown of all forest areas of one-quarter acre and larger.
i. Indications of the known presence of any tree pests and diseases.
j. Locations of standing, dead or diseased significant and heritage trees.
k. Locations of proposed building, structures, and impervious surfaces.
l. Grading, land disturbance, clearing, and trenching limits.
m. A three-year tree maintenance and preservation plan.
D.Tree replacement escrow. The applicant shall post a tree replacement escrow with the City in
the amount of $1,750.00, or 125% of estimated cost to accomplish compliance with an
18
approved forest management plan, whichever is greater. The escrow will be held by the City
until successful completion of final planting inspection, assurance that the trees have survived
for at least one growing season, and are covered by at least a one-year warranty for
replacement. The escrow may be held for longer to ensure viability of trees. Once the escrow is
reimbursed to the applicant, it is still the applicant’s responsibility to maintain the replacement
trees for three years after planting during the three-year maintenance period, and replace any
trees lost during the three-year maintenance period.
E.Exemptions
1.Interior structure improvements that do no expand the current footprint of the
structure
2.Tree removal related to public improvement projects, including but not limited to: road
reconstruction and improvement, parks, infrastructure work or repair, stormwater
treatment projects, and utility work or repair.
3.Emergency work to protect public health.
4.Removal of a hazardous, dead, dying, or diseased trees, unless those trees were planted
as part of a forestry management or other tree replacement plan, in which case they
shall be replaced based on the requirements of the approved plan.
5.Alteration of the forest canopy to improve tree health/diversity is recommended as part
of a forest management plan approved by the City’s Natural Resources Coordinator.
6.Tree removal as part of an approved native vegetative community restoration plan to
restore or enhance native woodlands, savannas, prairies, or wetland areas.
7.Removal of non-native trees that the City deems are invasive or noxious.
8.Commercial tree nursery and landscape operations.
9.In cases where a tree is causing a safety concern.
B.Safeguarding Preserved Trees
All development and redevelopment projects in the city shall be designed with the preservation
of the urban forest, natural woodlands, and significant trees in mind. The following criteria will
be considered to ensure survival of trees scheduled to be preserved:
a.Size of lot or project to be developed.
b.Tree size.
c.Species, role, and health of trees.
d.Tree life span.
e.Sensitivity to disease.
f.Nuisance characteristics.
g.Sensitivity to grading and grade change.
h.Transplanting potential.
i.Effects on the functioning of a development.
Prior to issuance of a grading or building permit the Natural Resources Coordinator may require
one or all the following measures be used to safeguard preserved trees:
Commented [RH21]: Plan will require conservation
easement or other legal means to ensure that woodland
preservation area or groups of high priority trees or
significant trees are not intentionally destroyed after the
development has been approved.(MTKA) (this would
prevent reselling of the land and allowing for clearing by the
new owner and so on- until the property is potentially
cleared entirely)
Plan should provide for protection of trees neighboring the
worksite so that any activity, as defined by
“remove/removal” in the definition portion of this
ordinance
Commented [HS22]: I think that we are asking too much
if we do not exempt improvements that are wholly in the
interior of a home and therefore do not impact trees.
Commented [HS23]: Why are we taking this out?
Commented [KS24]: Do we want to include this?
Commented [RH25R24]: No - too vague.
Commented [HS26R24]: If there is a safety concern with
a tree, I think that should go through the NR Coordinator.
There should be a way to fast track addressing trees that are
a hazard.
19
1)Tree protective areas shall be designated at a minimum of the CRZ of trees
or drip line, whichever is greater, whenever possible. Saving forests and
groups of trees is encouraged over protecting individual trees scattered
across the site.
2)Layout of the project site utility and grading plans shall accommodate the
forest and tree preservation areas. Utilities are recommended to be placed
along corridors between tree preservation areas and use of common
trenches or tunnel installation if possible.
3)Custom grading, retaining walls, or tree wells to maintain existing grade for
preserved trees should be utilized.
4)Suitable tree protection fencing in active areas includes use of orange
polyethylene laminar safety fencing, woven polyethylene fabric (silt
fencing), or similar high visibility fencing. Fencing shall be self-supportive.
Tree protection fencing shall be maintained and repaired by the applicant
for the duration of construction.
5)Use of passive forms of tree protection may be allowed, such as continuous
heavy-duty rope or flagging (heavy plastic four inches or wider) or other
easily recognized barriers to vehicles and people.
6)Active tree protection areas with “Tree Save Area” signs posted and
readable from at least ten feet away.
7)Additional protection, signage, and buffer distances around Heritage trees
in order to protect their value and legacy.
8)Minimize tree wounding by felling or removing trees in a direction away
from preserved trees.
9)Construction site activities such as parking, material storage, concrete
washout, placement of holes, etc., shall be arranged so as not to encroach
on tree preservation areas.
10)Measures such as deep mulching may be required if root pruning or root
compaction will occur.
11)Identify and prevent oak wilt infection. Treat all known oak wilt infected
areas with current accepted guidelines including root cutting and removal of
infected trees. If pruning oaks is required between April 1 and October 31,
fresh wounds shall be covered with nontoxic tree wound sealant or latex
paint.
All developments and redevelopment projects in the City shall be designed to preserve forests
and significant trees, where such preservation would not adversely affect the public health,
safety, or welfare of Mendota Heights citizens. The city may prohibit removal of all or a part of a
forest or of heritage or significant trees.
Commented [RH27]: Consider striking this statement.
What if individual trees are high value trees? Confusing.
Commented [RH28]: Strike “recommended”
Commented [HS29R28]: Can the city mandate this in a
way that is feasible?
Commented [RH30]: Delete should
Commented [RH31]: Before construction or site work –
including any tree removal – tree protection fencing or
other approved protection measures must be installed for
city staff inspection. The location of the fencing/protection
measures must be in conformance with the approved tree
preservation plan and must be maintained throughout the
course of construction or site work. (MTKA)
No construction, compaction, construction access,
stockpiling of earth, storage of equipment or building
materials, or grading of any kind may occur within the
critical root zone areas of trees to be protected. (MTKA)
Commented [RH32]: Delete number 10 - we don’t want
to allow this
Commented [RH33]: Require the clustering of buildings
or the relocation of roads, drives, buildings, utilitities, or
storm water facilities when relocation would preserve
protected trees. (MTKA)
20
If any significant tree designated as preserved in the approved forest management plan is cut,
damaged, or encroached upon during the construction process without city authorization and if
it is determined by the Natural Resources Coordinator that the damaged tree will not survive,
the said damaged tree shall be removed by the applicant at their expense and replacement
trees installed at a rate of two times the tree replacement calculations as described below.
C. Significant and Heritage Tree Replacement Calculation
1.If less than 20 percent of the total significant and/or heritage tree DSH inches on the
property is removed, the applicant shall replace one tree per significant or heritage tree
removed. Replacement trees shall be a minimum of one caliper inch in size.
2.If 20 percent or more of the total significant or heritage tree DSH inches is removed, the
applicant shall mitigate all significant and heritage tree DSH inches using the following
formula:
A= Total DSH inches of significant trees removed due to land alteration
B= Total DSH inches of significant trees located on the property
C= Tree replacement constant (1.5)
D= Total DSH inches of specimen trees saved (for each one DSH inch of significant or
heritage tree saved=1/2 DSH inches)
E= Replacement trees (#of caliper inches)
[((A/B - .2) x C) x A] - [D/2] = E
X-X-6: TREE MITIGATION
The applicant shall mitigate loss of significant and heritage trees by planting replacement trees
in appropriate areas on the property in accordance with section D. Significant and Heritage Tree
Replacement Calculation and as indicated in the applicant’s approved forest management plan,
if required. Trees shall not be planted within 15 feet of property lines without written
permission of the affected adjacent property, nor shall trees be planted at lot corners in a way
that obstructs a driver’s line of sight. If the replacement requirement is not feasible, the city’s
Natural Resources Coordinator can approve additional tree replacement steps, including a fee
assessment to be used toward the City’s tree planting fund. The City may require post-
construction tree care.
In order to preserve diversity and provide protection from tree disease and pests; where ten or
more replacement trees are required, not more than 20 percent shall be of the same family, not
more than 10 percent of the same genus, and not more than 5 percent of the same species,
unless approved by the City’s Natural Resource Coordinator. Tree species of the genus Acer shall
be limited to 10 percent of total replacement trees planted, due to its over-abundance in the
City’s forest canopy. A minimum of 50 percent of replacement trees must be species native to

Minnesota or recommended by the Department of Natural Resources or University of
Minnesota Extension. Planting of trees recommended from the Minnesota Department of
Natural Resources’ Best Native Yard Trees for our Changing Climate (state.mn.us), Northern
Institute of Applied Climate Science, or the Climate Change Response Framework is encouraged.
All replacement trees shall be healthy and free from insect or disease infestations. Replacement
trees shall be no less than a one-caliper inch deciduous or six-foot height conifer tree unless
approved by the City’s Natural Resources Coordinator. No more than three consecutive trees of
the same species may be planted in a continuous row, including around corners and in
groupings.
It is the applicant’s responsibility to maintain the replacement and preserved trees for at least
three years. The applicant is responsible for replacing any tree that dies during this three-year
period. The City may require additional post-construction tree care mitigation for preserved and
replacement trees.
The following woody plant species are considered invasive, and are prohibited from city
plantings and on development and redevelopment projects:
●Amur maple (Acer ginnala)
●Norway maple (Acer platanoides)
●Tree of heaven (Ailanthus altissima)
●Japanese barberry (Berberis thunbergii)
●Siberian pea shrub (Caragana arborescens)
●Oriental bittersweet (Celastrus orbiculatus)
●Russian olive (Elaeagnus angustifolia)
●Autumn olive (Elaeagnus umbellata)
●Winged burning bush (Euonymus alatus)
●Glossy buckthorn (Frangula alnus)
●Non-native bush honeysuckles (Lonicera tatarica, L. morrowii, L. x bella, and L.
maackii)
●White mulberry (Morus alba)
●Amur cork tree (Phellodendron amurense)
●White poplar (Populus alba)
●Common buckthorn (Rhamnus cathartica)
●Black locust (Robinia pseudoacacia)
●Multiflora rose (Rosa multiflora)
●Siberian elm (Ulmus pumila)
●Japanese Tree Lilac (Syringa reticulata)
Trees that are overly susceptible to diseases that cause tree death, such as Dutch Elm Disease or
Emerald Ash Borer, should not be planted unless they are a resistant variety or cultivar.
Commented [RH37]: Lets say 100% and ask for climate
resiliant trees, not trees that are native to MN. The two
categories are not necessarily the same.
Commented [RH38]: This list is not exhaustive. New
invasive species are discovered regularly and may be added
to this list based on information from ???? (noted source)
22
Replacement trees should be of a similar species to the tree it is replacing and appropriate for
the planting location; including soil, moisture, and sunlight conditions . Replacement trees shall
consist of certified nursery stock as defined by current Minnesota Statutes and shall be hardy for
USDA plant hardiness zones 4 or 5. Trees shall be planted in accordance with the American
National Standard for Tree Care Operations – ANSI A300, Part 6.
X-X-7: DISEASED TREES
The health of trees in the City is threatened by tree pests, which can result in hazardous trees
that cause property damage or personal injury. The loss of trees, or presence of diseased and
hazardous trees on public and private property depreciates the value of property within the City
and impairs the safety and general welfare of the public. In accordance with MN State Statutes
89.01, and 89.51-.64, the provisions of this section are adopted as an effort to control and
prevent the spread of tree pests.
The Natural Resources Coordinator may declare any vertebrate or invertebrate animal, plant
pathogen, or plant in the community threatening to cause significant damage or death to trees
in the community to be a tree pest and prescribe control measures to effectively eradicate,
control, or manage the tree pest as defined by MN Stats. 89.001.
The Natural Resources Coordinator may notify in writing the owner of record or occupant of the
premise that a diseased or hazard tree exists. The notice may specify required abatement
measures to be taken to abate the nuisance in accordance with City Code 4-1-5. When removing
and managing diseased trees, property owners shall follow any diseased tree management plans
that are put forth by the City, Dakota County, or the State of Minnesota and comply with all
quarantine requirements and restrictions.
If a diseased, nuisance, dead, dying, or hazard tree exists within publicly-owned property or
rights-of-way, including boulevard trees, the City may remove, at any time, diseased, nuisance
or hazard trees without the permission of, or notice to, adjacent property owners.
X-X-8: ENFORCEMENT
The City shall be responsible for the enforcement of this chapter and determine any violations.
All land use, building, and grading permits shall be suspended until the applicant has corrected a
violation. The city reserves the right to inspect the site or property at any reasonable time for
compliance with the forest management plan and forest alteration permit. If the city finds the
site in violation, the city may issue a stop work order until conditions are corrected. Conditions
that are not corrected within the required timeframe may result in forfeiture of escrow.
Commented [SW(39]: Species for replacement trees is
covered better on the previous page and this partly
contradicts that.

DATE: December 13, 2023
TO: Natural Resources Commission
FROM: Krista Spreiter, Natural Resources Coordinator
SUBJECT: Partners in Energy Program Update
Background
As part of Goal 5, Sustainability, the Sustainability Committee has worked to prepare and submit
an application to Xcel Energy’s Partners in Energy program. The Partners in Energy Program
partners with communities to help reduce energy use, provide climate change adaption, and
increase and plan for energy sustainability. This program is able to tailor its services to each
community’s goals and needs to create a plan that allows communities to make wise energy
decisions. As part of this plan, the City hopes to coordinate and partner with citizens, businesses,
schools, and other community groups, to promote renewables, encourage and implement energy
conservation and sustainability, and work toward greenhouse gas reduction goals throughout
the City, including at city-owned facilities.
The Commission officially recommended the program to City Council, and the recommendation
was approved, at the October 3rd, 2023 City Council meeting. The City has now been accepted
into the program and has begun the initial planning process. A kickoff meeting will be held with
Partners in Energy Staff, City Staff, and members of the Sustainability Committee on December
15th at 1p. The purpose of the kickoff meeting will be to explain the goals of the program, decide
on a process to get community input, and identify possible members of the larger Energy Action
Team.
