URBAN TREE GUIDELINES
Guidelines developed by the City to implement this chapter and provide proper tree care.
All trees planted on public lands in the City are the property of the City and shall be designated as "street trees." The City shall have exclusive jurisdiction and supervision over all street trees. The City shall have the authority to plant, trim, prune, spray, treat, preserve and remove trees on public lands to ensure public safety, to eliminate public nuisance trees, to preserve the symmetry and beauty of such public places, and to prevent endangerment of public and private property.
A. 
The City shall determine a selection of sites and species of trees that are appropriate for specific areas.
B. 
Where the sidewalk grass strip (between the sidewalk and the street) is less than three feet in width, steps should be taken to plant on the side of the sidewalk farthest from the street or on private property, or larger planting areas may be developed in the sidewalk area; however, at a minimum, no tree shall be planted in an area of less than 16 square feet of pervious surface.
C. 
The City shall specify the distance trees shall be planted from street intersections.
D. 
The City shall abide by pertinent codes when determining the placement of trees.
Utility companies are required to notify the City Administrator in writing a minimum of three business days prior to pruning, treating or removing street trees for line clearance by reporting the nature of the pruning, treating or removal work, and where and how long they will be engaged in such work. Except in emergency situations where persons or property are in imminent danger, the City shall have the right to notify the utility of its intent to have the street tree(s) affected by the pruning, treating or removal inspected by a consulting arborist to provide instruction on how the street tree(s) shall be pruned, treated or removed by the utility in the manner least damaging to any affected street tree(s). The utility shall abide by the instructions of the consulting arborist to the maximum extent possible in conducting the pruning, treating or removal of the affected street tree(s) so as to best ensure their health and vitality, any those of any other affected street trees. Nothing herein shall be deemed to deprive the utility company of the right to fully exercise its lawful and enforceable easement rights. Any damage to or removal of street trees resulting from the violation of this section shall be a violation of this chapter subject to fine and enforcement action under § 210-17 of this chapter. This section shall not apply to the Municipal Services Corporation.
A. 
Building permits, grading permits, site plans or any other form of modification or action that would affect a street tree shall be reviewed by the City for compliance with this chapter. If the proposed activity requires action impacting upon a street tree either by the City or the applicant, the permit shall be referred to the City Administrator for action.
(1) 
Where a planned action includes the development of a new public or private street, the construction plans shall include the location, size and species of all street trees. The City shall install the street trees on any public street and provide the first three years of maintenance at the expense of the developer or owner of a property to be developed. The City, at its sole discretion, may permit the developer to install the street trees as part of the project construction. The developer shall provide a bond or other approved security to cover the costs of installation, replacement and maintenance of the street trees for three years from the date of installation.
(2) 
No street tree shall be planted, pruned or removed during any construction activity without the approval of the City.
(3) 
The applicant will be responsible for posting a bond in the amount of 100% of the value of the affected tree or trees as determined by the City or a consulting arborist hired by the City to pay for any damage to street trees which may occur during construction.
(4) 
Any damage to or removal of street trees without a permit or prior approval shall be a violation of this chapter subject to fine and enforcement action under § 210-17 of this chapter.
B. 
Any person who proposes to do work within the dripline area, or access work through the dripline area, of a street tree shall install a protective barrier. The protective barrier shall be placed around the street tree prior to permitted activities and shall remain in place until all construction activity is terminated. No equipment, chemicals, soil deposits or construction materials shall be placed within the protective barriers.
C. 
Any person who proposes to do work within the dripline area, or access work areas through the dripline area, of a street tree shall obtain and provide to the City a security and performance bond in the amount of 100% of the value of the tree or trees as determined by the City or a consulting arborist hired by the City. The security and performance guarantee shall be issued by an insurance company, bank or other entity approved by the City and shall be conditioned upon the faithful performance of all work in close proximity to the tree or trees involved and shall specify that if the City determines that the person responsible for the work has failed to faithfully perform or is in default under any of their obligations as to such trees, the obligor shall make good and reimburse the City such funds as may be necessary to pay damages incurred by the City.
A. 
Any application for development, or for a building or demolition permit, shall be accompanied by a statement by the property owner or authorized agent which discloses whether any street trees exist within 30 feet of the property which is the subject of the application, and describes each such tree, its species, size, dripline area, and location. This requirement shall be met by including the information on plans submitted in connection with the application.
B. 
In addition, the location of all other trees on the site and in the adjacent public right-of-way which are within 30 feet of the area proposed for development, and trees located on adjacent property with canopies overhanging the project site, shall be shown on the plans and identified by species and size.
C. 
The City may require submittal of such other information as may be necessary to further the purposes of this chapter, including, but not limited to, photographs.
D. 
Disclosure of information pursuant to this section shall not be required when the development for which the approval or permit is sought does not involve any change in building footprint nor any grading or paving.
E. 
Knowingly or negligently providing false or misleading information in response to this disclosure requirement shall constitute a violation of this chapter.
It shall be the responsibility of every property owner or occupant to maintain the trees on their property in a safe and healthy manner and to keep trees properly trimmed and pruned so as to avoid hazards to persons, property and other vegetation.
A. 
The City and its designated agents shall have the right, from time to time, to enter upon private property in order to inspect the trees and shrubs located upon such private property. The City shall seek the property owner's permission to conduct such an inspection, but in no event shall any entry upon private property by the City or its agents or contractors for purposes authorized by this chapter be deemed a trespass. Should a condition of extreme danger be observed by the City, and should the City Administrator make a finding that any tree or part thereof constitutes an immediate danger to persons, property or other vegetation, the City shall direct the property owner to remove the tree, or the portion thereof constituting a danger, forthwith.
B. 
The method of notification to the property owner shall be in one or more of the following ways:
(1) 
By personal delivery of the order to the owner or owners.
(2) 
By delivering the order to an adult residing on the premises.
(3) 
By mailing the order by registered or certified mail to the last known address of the owner on the premises.
(4) 
By publishing the order in a local newspaper for three consecutive days.
C. 
The order shall set forth the time limit for compliance, which shall depend upon the degree of danger created by the tree, but shall in no case be longer than 30 days. In cases of extreme danger, the City shall have the authority to require immediate compliance.
D. 
If, at the end of the time set forth in the order, the tree has not been removed, the City shall have the tree, or the portion thereof constituting a danger, removed. The costs of this service, including labor, equipment and materials, shall be assessed to the property owner. If the costs of remedying the condition are not paid within 30 days after receipt of a statement from the City, the amount shall become a lien upon the property to be included in the tax bill rendered to the property owners and shall be collected in the same manner as other taxes against such property.
A. 
When a tree, regardless of its location, has partially failed, or it is apparent it is about to fail, and persons or property are threatened, the tree may be removed without City review or approval. The City does not require a consulting arborist's report before the removal of a tree in this instance.
B. 
When a street tree is removed as a hazardous tree, the hazard must be substantiated after the fact by the property owner and certified arborist with photographs, abatement information, insurance claim or other relevant information. This information shall be submitted to the City within five days after removal.
C. 
Any hazardous tree removed from public lands may be replaced at the discretion of the City.
Because diseases of trees on private property can be spread to street trees, it shall be the responsibility of any person, for any tree or other vegetation on their property, to treat or remove any tree or vegetation so diseased or insect infested as to constitute a hazard to persons, property or other vegetation, if directed by the City.
A. 
Upon determining that any tree upon private property is diseased or infested with insects, the City shall notify the property owner, in writing, describing the condition, stating the actions necessary for correction and setting forth a reasonable time in which the action must be taken.
B. 
In the event the property owner fails to take the required corrective action, the City is authorized, in the public interest, to enter the property to spray, trim, prune, treat or remove the diseased tree or any part thereof. The cost of this service, including labor, equipment and materials, shall be assessed to the property owner and shall constitute a lien upon the relevant property. No such entry on to private property by the City, its employees, agents and contractors shall be deemed a trespass.
C. 
If, after utilizing all techniques, methods and procedures which could reasonably be expected to save a tree, said tree is deemed to be dead, dying, in a dangerous condition, unsafe or likely to cause damage, the tree shall be declared an immediate danger and abated as set forth in § 210-9A of this chapter.
D. 
The City shall cause to be made periodic inspections for Dutch elm disease, shall take samples, and require treatment as may be necessary to control the spread of such disease. Infected tree wood and bark shall not be stored for fuel or similar future use; and shall be transported to a licensed landfill for appropriate and lawful disposal. Elm trees found to be infected with Dutch elm disease and determined to be untreatable shall be abated as set forth in this section.
E. 
Public nuisance trees. Any tree or shrub growing on public or private property, which tree or shrub is endangering, or which in any way may endanger, the security or usefulness of any public street, sewer, or sidewalk or the full and safe operation of public utility wires, is hereby declared to be a public nuisance and may be removed at the discretion of the City.
F. 
Tree permit.
(1) 
The City is responsible for the maintenance of the street trees on City-owned property, rights-of-ways, medians, parks, and City-owned easements. The City will not maintain trees that are on privately owned property except as provided in this chapter. The City will maintain street trees, in order to remove dangerous debris and tree material for public safety and welfare.
(2) 
With the advance written approval of the City, property owners abutting street trees on City-owned easements, parks, medians, and rights-of-ways may, at the property owner's expense, have trees trimmed by a certified arborist or other qualified and insured contractor approved and licensed by the City, or under the supervision of a Tree Commission Member or City employee.
(3) 
A tree permit is required for the planting, removal or pruning of branches of street trees. Root pruning of street trees and any disturbance or compaction within the dripline area requires a tree permit. A resident must obtain a tree permit to ensure that proper care is given to street trees. Street tree work completed without a permit shall be a violation of this chapter subject to fines and enforcement actions under § 210-17 of this chapter.
G. 
Private parties, whether acting pursuant to a tree permit or not, are responsible for the cost of repairing or replacing any City curbing or sidewalks damaged as a result of the pruning or removal of any tree or tree root. If a private party fails to repair or replace a damaged curb or sidewalk, the City may do so after 60 days' written notice. If the cost of repairing or replacing the affected curbing or sidewalk is not paid within 60 days after receipt of a statement from the City, the amount shall become a lien upon any real estate owned by the private party located in the City and shall be included in the tax bill rendered to such property owner and shall be collected in the same manner as other taxes against such property.
A. 
No person shall, without a valid tree permit, remove, destroy, break, cut or deface any street tree.
B. 
No person shall directly or indirectly permit any toxic chemical or any toxic substance to seep or drain or be emptied on or about any street tree.
C. 
No person shall directly or indirectly place stone, cement or other impervious materials about any street tree that will impede the free entrance of water or air to the roots of such trees without leaving an open and pervious space of ground about the trunk of such tree of not less than 16 square feet.
D. 
No person shall remove, damage, misuse or attach any foreign object to any guard or device placed or intended to protect any street tree.
E. 
No person shall attach or place any rope, wire, sign, handbill or any other thing on any street tree.
F. 
No person shall plant any tree in the public right-of-way unless the City grants a tree permit for such installation. The City may prepare a list of tree species recommended as street trees.
G. 
In the case of erection, demolition or repair of any building or structure, the owner thereof shall place or cause to be placed such guards around all nearby street trees to prevent injury to them.
H. 
It shall be a violation of this chapter for anyone to remove or cause to be removed a street tree, except as shall be permitted in this section:
(1) 
In the absence of conflicting development, street trees shall not be removed unless it is determined by the City, or on the basis of a tree report prepared by a consulting arborist, that the tree should be removed because it is dead, is hazardous, is a public nuisance, is a detriment to or is crowding an adjacent protected tree.
(2) 
Street trees shall not be removed unless the trunk or basal flare of the protected tree is touching or within the building footprint of a new structure, or the City has determined, or on the basis of a tree report prepared by a consulting arborist with other relevant information, that the tree should be removed because it is dead, is hazardous, is a detriment to or is crowding an adjacent protected tree.
(3) 
If no building footprint exists for new structures, street trees shall not be removed unless the City has determined, or on the basis of a tree report prepared by a consulting arborist with other relevant information, that the tree should be removed because it is dead, is hazardous, is a detriment to or is crowding an adjacent protected tree.
(4) 
If removal is allowed because the tree trunk or basal flare is located in the building footprint or because the City has determined that the tree is so close to the building area that construction would result in the death of the tree, the tree removed shall be replaced in accordance with the Urban Tree Guidelines.
(5) 
In all circumstances in which the City has allowed for the removal of street trees, such trees shall be replaced at the discretion of the City.
I. 
Except in case of immediate necessity for the protection of life or property, willful injury or disfigurement of any street tree shall be a violation of this chapter.
J. 
No person shall:
(1) 
Attach any sign, notice or other object to any street tree or fasten any wires, cables, nails, spikes or screws to any street tree in a manner that could prove harmful to the tree, except as necessary in conjunction with activities in the public interest.
(2) 
Pour any material on any street tree or on nearby ground which could be harmful to the tree.
(3) 
Cause or encourage any unnecessary fire or burning near or around any street tree.
(4) 
Construct a concrete, asphalt, brick or gravel sidewalk or otherwise fill up the ground around any street tree so as to cut off air, light or water from the roots.
(5) 
Pile building material or equipment around any street tree so as to cause injury thereto.
(6) 
Discharge or pour salt, salt water, oil or other liquids or materials at any place or in any manner that causes injury to any street tree.
(7) 
Without first obtaining a tree permit, place or maintain any stone, cement or other substance which impedes the natural passage of water and air to the roots of any street tree.
K. 
Protective barriers shall be placed around street trees, prior to land preparation or construction activities, and shall remain in place until all construction activity is terminated. No equipment, chemicals, soil deposits or construction materials shall be placed within the protective barriers.
Nothing in this chapter limits or modifies the existing authority of the City under Chapter 213 (Subdivision of Land) and Chapter 230 (Zoning) to require trees and other plants not covered by this chapter to be identified, retained, protected and/or planted as conditions of the approval of development. In the event of conflict between provisions of this chapter and conditions of any permit or other approval granted pursuant to Chapter 213 or Chapter 230, the more protective requirements shall prevail.
Nothing in this chapter shall be deemed to impose any liability upon the City or upon any of its officers, employees or Commission members. The City and its officers, employees and Commission members shall be immune from suit for damages as a result of any lawful action taken pursuant to the terms of this chapter. Nothing in this chapter shall relieve the owner or occupant of any private property from the duty to keep trees upon private property in a safe condition.

(1) 
Stop work; temporary moratorium.
(a) 
If a violation occurs during development, the City may issue a stop-work order, suspending and prohibiting further activity on the property pursuant to the grading, demolition and/or building permit(s) (including construction, inspection and issuance of certificates of occupancy) until a mitigation plan has been filed with and approved by the City, agreed to, in writing, by the property owner(s), and either implemented or guaranteed by the posting of adequate security.
