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.
The following words, terms, and phrases, when used in this bylaw,
shall have the meanings ascribed to them in this section, except where
the context clearly indicates a different meaning:
AGGREGATE DIAMETER
The combined diameter of a multiple-trunk tree measured at
breast height.
BUILDING ACTIVITY
One of the following types of work performed on a lot:
A.
Work performed pursuant to a special permit (as defined in MGL
c. 40A, § 9, and in the Lynnfield Zoning Bylaw);
B.
Work performed pursuant to site plan approval (as defined in
the Lynnfield Zoning Bylaw);
C.
Construction of a new dwelling (including after razing an existing
dwelling);
D.
Construction of a subdivision; or
E.
Clearing, grading or other site preparation work performed within
12 months prior to undertaking any of the above.
CALIPER
Diameter of a tree trunk in inches. For trees up to and including
four inches in diameter, the caliper is measured six inches above
the existing grade at the base of the tree. For trees larger than
four inches in diameter, the caliper is measured 12 inches above the
existing grade at the base of the tree.
CERTIFIED ARBORIST
An arborist certified by the Massachusetts Arborists Association
or International Society of Arboriculture, or any successor organization.
CRITICAL ROOT ZONE or CRZ
The minimum area beneath the canopy of a tree which must
be left undisturbed in order to preserve a sufficient root mass to
give a tree a reasonable chance of survival. The CRZ is represented
by a circle centering on the tree's trunk and extending outward
towards the tree's dripline. The minimum radius of the CRZ shall
be determined by multiplying the tree's diameter breast height
in inches by 18. For example: A tree with a DBH of 20 inches shall
have a CRZ with a minimum radius of 360 inches or 30 feet (20 inches
x 18 inches = 360 inches or 30 feet).
HAZARDOUS TREE
A tree that is interfering with existing structures, utilities,
streets, sidewalks or other existing improvements; or is dead, diseased,
injured, or dangerously close to existing structures; or is causing
disruption of public utility service, drainage or passage problems
upon rights-of-way; or poses a threat to pedestrian or vehicular safety;
and/or that is harming the health or condition of other trees on the
same site.
INVASIVE SPECIES
Any plant listed on the most recent version of the Massachusetts
Prohibited Plant List as published by the Massachusetts Department
of Agriculture.
OVERSTORY TREE
A tree that will generally reach a mature height of greater
than 40 feet.
PROTECTED TREE
Any tree within a tree border having a diameter of six inches
DBH or larger or having an aggregate diameter of 12 inches DBH or
larger.
REMOVE REMOVED, REMOVAL or REMOVING
The cutting down of any protected tree and all other acts
that directly or indirectly result in the death of a protected tree
in the prior 12 months or within two years thereafter, as determined
by a certified arborist based on arboricultural practices recommended
by the International Society of Arboriculture (I.S.A.), including,
but not limited to, damaging, poisoning, excessive pruning or other
direct or indirect actions.
TREE BORDER
A defined area along the perimeter of a lot.
TREE PERMIT
