[HISTORY: Adopted by the Town Meeting of the Town of Lynnfield 10-18-2021 ATM by Art. 3. Amendments noted where applicable.]
A. 
The intent of this Tree Preservation Bylaw (the "bylaw") is to encourage the preservation and protection of trees during new building activity (meaning only the activities defined in § 225-13 below) by:
(1) 
Designating specific areas of a lot where trees must be protected; and
(2) 
Requiring mitigation for trees removed, by either:
(a) 
Replanting trees; or
(b) 
Collecting fees to support the Town's tree planting and maintenance efforts.
B. 
In no event may the Town deny a landowner's right to remove a tree subject to this bylaw; any landowner may remove a tree or trees, on the condition that they undertake one of the mitigation options set forth herein.
C. 
Trees are recognized for their abilities to mitigate heat island effects; provide shade cover; reduce energy consumption; improve air quality; reduce noise pollution; reduce topsoil erosion and stormwater runoff; provide wildlife habitat; sequester carbon; enhance the quality of life and the environment of the Town; increase property values; and enhance the overall appearance of the community. The Town of Lynnfield (the "Town") deems that the preservation and protection of certain trees on private property, and the requirement either to replant trees, to replace those removed or collect financial contributions to support the Town's tree-planting and maintenance efforts are public purposes that protect the Town's public health, welfare, environment and aesthetics. No part of this bylaw shall discourage the removal of hazardous trees (as defined below), an act which may be important to public health and safety, nor shall any part of this bylaw discourage the removal of a tree that, by size or otherwise, is not subject to the protections set forth herein.
A. 
The terms and provisions of this bylaw shall apply to any protected tree located within a tree border during building activity as defined in § 225-13 that is not owned by the commonwealth, with the following exception:
(1) 
The terms and provisions of this bylaw shall not apply to parcels with more than 50% of land permanently conserved as open space pursuant to Article 97 of the Articles of Amendment to the Constitution of the Commonwealth of Massachusetts or a perpetual restriction under MGL c. 184, §§ 31 through 33.
B. 
No person shall commence building activity (as defined in § 225-13 below) on any lot without first obtaining a tree permit or a certificate of exemption from the Planning Board or its authorized enforcement agent.
C. 
The location of the tree border is defined by Table 1 below. In the case of a new subdivision, the tree border shall be based on the new lot lines approved for the subdivision.

A. 
Exempt building activity:
(1) 
Any activity that does not fall within the definition of building activity set forth in § 225-13, below, is exempt from this bylaw.
(2) 
A tree permit is not required if a certificate of exemption has been granted by the Planning Board or its authorized enforcement agent.
(3) 
Granting a certificate of exemption is at the discretion of the Planning Board and its authorized enforcement agent based on whether the building activity has the potential to harm a protected tree. The Planning Board or its authorized enforcement agent shall issue a certificate of exemption if the proposed building activity does not have potential to harm a protected tree.
B. 
Pruning: A tree permit is not required for the pruning of protected trees. However, excessive pruning may be considered tree removal.
C. 
Emergencies: If any protected tree shall be determined to be in a hazardous condition so as to immediately endanger the public health, safety or welfare or cause an immediate disruption of public services and require immediate removal without delay, the landowner shall seek authorization from the Planning Board if conditions allow and oral authorization may be given by the Tree Warden, Planning Board or its authorized enforcement agent to remove such tree, utilizing such professional criteria and technical assistance as he/she deems necessary. If the emergency condition does not allow time or opportunity to seek prior authorization then the emergency work shall proceed without it.
D. 
Waiver: The requirements of this bylaw may be waived by the appropriate Town officials during the period of an emergency such as a tornado, windstorm, flood, or other act of God.
When a tree permit is granted, tree-preservation measures are prescribed as follows:
A. 
Tree Save Area:
(1) 
Each protected tree to be retained on property planned for a building activity permit shall be protected by the establishment of a Tree Save Area, which at a minimum must include the critical root zone of the protected tree(s).
(2) 
The Tree Save Area must be adequately marked prior to the commencement of building activity and maintained in place until work is completed on the property.
(3) 
An applicant may choose to encroach within the CRZ of a protected tree; however, such proposed action shall require the applicant to submit a maintenance plan for the tree, to be prepared, stamped, dated and signed by a certified arborist as part of the tree permit application. Under these instances, the Tree Save Area may be reduced to protect only those areas of the CRZ not proposed for encroachment.
B. 
Maintenance of protected trees: Should such tree die within a twenty-four-month period from the later of (A) planting or (B) the date of issuance of a certificate of occupancy, if applicable, of the building activity, the owner of the property shall be required to provide mitigation consistent with the requirements for the removal of a protected tree as contained herein within nine months from the death of the original tree.
When protected tree removal is permitted, mitigation through planting of replacement trees is prescribed as follows:
A. 
No mitigation measures are required for the permitted removal of hazardous trees or for the removal of any tree not within the definition of protected tree.
B. 
For each inch of DBH of the tree(s) removed, at least one inch of caliper of new tree(s) must be replaced in accordance with the following:
(1) 
Each new tree must have a minimum caliper of two inches.
(2) 
If the protected tree to be removed is an overstory tree species, the replacement tree(s) to mitigate the removal shall be an overstory tree species.
(3) 
Replanting shall occur no later than 18 months after tree removal.
(4) 
A replacement tree shall be planted on the same lot from which the tree was removed or on land abutting the said lot with the express written approval of the owner of such abutting land.
(5) 
A replacement tree must not be an invasive species.
C. 
Maintenance of replanted trees: All new trees replanted to mitigate the removal of protected trees shall be maintained in good health for a period of no less than 24 months from the date of planting. Should such tree die within this twenty-four-month period, the owner of the property shall replace it.
When protected tree removal is permitted, mitigation may be effected through contribution to the Tree-Replacement Fund, as prescribed as follows:
A. 
The Tree-Replacement Fund is an existing revolving fund of the Town. Any payments into the Tree-Replacement Fund required by this bylaw shall be deposited in the Tree-Replacement Fund and shall be used in accordance with Subsection C of this § 225-6.
B. 
Payment in lieu of planting replacement tree(s): In lieu of planting a replacement tree as provided in § 225-5, a person who has been granted a tree permit may make a contribution to the Tree-Replacement Fund in an amount equal to the cost to replace the tree, which shall be determined by the Tree Warden based on the Town's current cost to purchase and install trees.
C. 
Maintenance of Tree-replacement fund: All sums deposited into the Tree-Replacement Fund pursuant to this bylaw shall be used solely for the purposes of buying, planting and maintaining trees on public property in Lynnfield, and for no other purpose whatsoever. In addition, at least once each year the Town Accountant shall audit the receipts and expenses of the Tree-Replacement Fund to ensure the accuracy and propriety of its transactions.
This bylaw is adopted under authority granted by the Home Rule Amendment of the Massachusetts Constitution and the Home Rule statutes.
The Planning Board or its authorized enforcement agent shall administer, implement, and enforce this bylaw, and any rules and regulations adopted thereunder. Any powers granted to or duties imposed upon the Planning Board may be delegated to its employees or agents under the Board's direct supervision.
The Planning Board may promulgate rules and regulations to effectuate the purposes of this bylaw. Failure by the Planning Board to promulgate such rules and regulations shall not have the effect of suspending or invalidating this bylaw. Such rules may prescribe the size, form, contents, style, and number of copies of plans and specifications, the procedure for the submission and approval of such plans, and the procedure for determining final compliance with these regulations. The adoption or amendment of rules and regulations shall be after a public hearing to receive comments on the proposed or amended rules and regulations. The public hearing shall be advertised once in a newspaper of general local circulation, at least 14 days prior to the date of the public hearing.
A. 
Any person aggrieved by a decision of the authorized enforcement agent may file an appeal with the Planning Board. Said appeal must be in writing and must be received by the Planning Board within 10 business days of issuance of the authorized enforcement agent's written decision. The Planning Board shall conduct a public hearing on the appeal and shall give the public notice thereof, at the expense of the applicant. Public notice shall include mailed notice to all persons owning land within 300 feet of any part of the applicant's land at least 14 days before said hearing. The Planning Board shall rule within 20 days of the public hearing. No protected trees shall be removed while an appeal is pending.
B. 
Appeals of final decisions of the Planning Board shall be pursuant to MGL c. 249, § 4.
A. 
Notice of violation: Any person who violates any of the provisions of this bylaw shall be notified by the Planning Board of the specific violation by certified mail, return receipt requested, or by hand delivery. The notice shall set forth the nature of the violation and the date by which the protected tree(s) is to be mitigated with the planting of replacement trees or payment to the Tree-Replacement Fund, for purposes of computing the "per day" violation fine.
B. 
A tree permit may be suspended or revoked at any time by the Planning Board or its authorized enforcement agent upon written notice to the tree permit holder that the tree permit holder has failed to comply with either this chapter or the conditions of the tree permit. The written notice shall be sent by certified or registered mail, return receipt requested, or by hand delivery, and shall provide an opportunity for the tree permit holder to correct the noncompliance and apply for a renewal of the tree permit upon compliance, where practicable. The suspension or revocation of a tree permit in accordance with this subsection shall not affect the validity of a building activity permit. It shall, however, be cause for levying a fine or fines for violation of the tree permit and, if applicable, violation of the requirement for replacement of any removed or damaged trees.
C. 
Stop-work order:
(1) 
Upon notice from the Planning Board that work on any protected tree, or lot on which a protected tree is located, is being performed contrary to the provisions of this bylaw, such work shall be immediately stopped. The stop-work order shall be in writing and shall be given to the owner of the property involved, or to the owner's agent, or to the person doing the work; and shall state the conditions under which work will be permitted to resume.
(2) 
The Planning Board is also authorized to request the agency which has granted a building activity permit, to the extent permissible by law, to require the owner to cease any activity pursuant to the building activity permit that might affect such protected tree while a stop-work order is pending.
(3) 
Any person who shall continue any work in or about the protected tree or lot on which a protected tree is located after having been served with a stop-work order, except such work as that person is directed to perform to remove a violation or unsafe condition, shall be liable to a fine(s) per the table in § 225-12A. Each day during which a violation exists shall constitute a separate offense.
D. 
Injunctive relief:
(1) 
Whenever there exists a set of facts that make it more likely than not that a person is violating this bylaw or any term, condition or provision of an approved tree permit, the Town may, either before or after the institution of any other action or proceeding authorized by this bylaw, institute a civil action in the name of the Town for a mandatory or prohibitory injunction and an order of abatement demanding the defendant to correct the unlawful condition upon or cease the unlawful use of the property.
(2) 
Upon determination of a court that an alleged violation is occurring, it shall enter such order or judgment as is necessary to abate the violation. The institution of an action for injunctive relief under this subsection shall not relieve any party to such proceedings from any civil penalty prescribed for violation of this bylaw.
A. 
Removal without a permit: Each instance in which a protected tree is removed without a permit shall constitute a violation of this bylaw which shall be subject to a fine per the table below. This shall be in addition to the required payment for the replacement of the tree(s).
Offense

Each day such violation continues after the compliance date specified by the Planning Board in its notice of violation shall constitute a separate offense.
C. 
Failure to comply with a condition contained in a tree permit or stop-work order: Each instance where there is a failure to comply with a condition contained in a tree permit or stop-work order shall constitute a violation of this chapter which shall be subject to a fine in the amount per the table above.
