As used in article, the following terms shall have the meanings
indicated:
Any "person" as defined below, who applies for approval to
remove trees regulated under this article.
The diameter of a trunk as measured at a height of four feet
above grade.
An area of new home construction that includes the portions
of a private residential lot reserved for driveways and the actual
building foot print plus an additional 40 feet beyond the perimeter
of the building footprint and septic field.
The zone around the base of a tree where the majority of
the root system is found. This zone is calculated by multiplying the
diameter at breast height (DBH) of the tree by 1.5 feet. For example:
a tree with a 6" DBH would have a CRR = 6"x1.5' = 9'.
To cut off the branches, top or trunk of a tree.
The diameter of the trunk of a mature tree generally measured
at a point four and a half feet above ground level from the uphill
side of the tree. For species of trees where the main trunk divides
below the 4 1/2 foot height, the DBH shall be measured at the
highest point before any division.
A tree or limbs thereof that meet one or more of the criteria
below. Trees that do not meet any of the criteria below and are proposed
to be removed solely for development purposes are not hazard trees:
Has an infectious disease or insect infestation;
Is dead or dying;
Obstructs the view of traffic signs or the free passage of pedestrians
or vehicles, where pruning attempts have not been effective;
Is causing obvious damage to structures (such as building foundations,
sidewalks, etc.); or
Is determined to be a threat to public health, safety, and/or
welfare by a certified arborist or Licensed Tree Expert (LTE).
Any individual, resident, corporation, utility, company,
partnership, firm, or association.
The part of a street right-of-way between the public right-of-way
and the portion of the street reserved for vehicular traffic or between
the abutting property line and the curb or traveled portion of the
street, exclusive of any sidewalk.
To cut off or remove living or dead parts or branches of
a tree.
An individual who resides on the residential property or
contractor hired by the individual who resides on the residential
property where a tree(s) regulated by this article is removed or proposed
to be removed.
A tree planted in the sidewalk, planting strip, and/or in
the public right-of-way adjacent to (or specified distance from) the
portion of the street reserved for vehicular traffic. This also includes
trees planted in planting strips within the roadway right-of-way,
i.e., islands, medians, pedestrian refuges.
A woody perennial plant, typically having a single stem or
trunk growing to a considerable height and bearing lateral branches
at some distance from the ground.
The diameter of the trunk of a young tree, measured six inches
from the soil line. For young trees whose caliper exceeds four inches,
the measurement is taken 12 inches above the soil line.
To kill or to cause irreparable damage that leads to the
decline and/or death of a tree. This includes, but is not limited
to, excessive pruning, application of substances that are toxic to
the tree, over-mulching or improper mulching, and improper grading
and/or soil compaction within the critical root radius around the
base of the tree that leads to the decline and/or death of a tree.
Removal does not include responsible pruning and maintenance of a
tree, or the application of treatments intended to manage invasive
species.

branches of trees.
