Supplementary definitions. The following are intended to supplement definitions found in §
300-14, or elsewhere in the Code.
CERTIFIED ARBORISTAn individual who has obtained knowledge and competency in arboriculture or forestry through an accredited body such as the International Society of Arboriculture (ISA) arborist certification program, the American Society of Consulting Arborists, the New Jersey Society of Certified Tree Experts, the State of Connecticut Department of Environmental Protection or the New York State Cooperating Consultant Forester Program.
CERTIFIED ARBORIST REPORTA report prepared by a certified arborist containing specific information on the tree(s) and/or shrubs to be removed, including, but not limited to: species, size, location, condition, structure, height, crown integrity, crown spread, age, pruning history and presence of pests or disease. The report shall include the arborist's name, address, business affiliation, certification information and signature.
CLEAR-CUTTINGThe cutting of five or more trees with a diameter of six inches or more at a height of 54 inches (diameter at breast height or DBH) above the natural grade on a given lot within a twelve-month period.
CRITICAL ROOT ZONE (CRZ)The area containing the volume of roots necessary for maintenance of tree health and stability. The CRZ is determined as a circle with a diameter calculated from the diameter at breast height (DBH) using the equation: (DBH X 1.5) X 2, which typically extends beyond the dripline of the tree (as defined below).
DBH (DIAMETER AT BREAST HEIGHT)A standard measurement of tree size taken by measuring the diameter of the trunk at a height of 4.5 feet (54 inches) above ground level. Guidelines for determining DBH in some of the more complicated situations are as follows:
(1) If the tree has branches, bumps or forks that interfere with DBH measurement, measure below that point and record the height at which DBH was determined.
(2) If the tree is growing vertically on a slope, measure DBH from the uphill side of the slope.
(3) If the tree is leaning, measure DBH in the direction of the lean.
(4) If the tree splits into several trunks close to the ground (i.e., has a multistemmed or low-branched habit), the DBH of the tree is the sum of the DBH of each trunk.
DESTRUCTIVE PRUNING PRACTICESPruning of a mature tree in ways that are in violation of best practices, as defined by the American National Standards Institute Guidelines for Tree Pruning (ANSI A300 Part
1) destructive pruning practices include, but are not limited to, tree topping, defined as cutting back large-diameter branches to stubs, and removal of more than 25% of a tree's canopy.
DOWNED TREEA tree that has fallen over or is broken and is lying on the ground or on a structure.
DRIPLINEThe outermost limit of the canopy of a tree as delineated by the perimeter of its branches and which, extended perpendicularly to the ground, encloses the tree.
GIRDLINGAn activity that removes or injures the bark of a tree trunk, typically extending around much of the tree's circumference.
HAZARDOUS TREEA tree that exhibits serious defects, that is, obvious and visible signs that the tree is failing and that it presents an imminent threat to the health and safety of persons, property, power lines or places where people gather. Examples of serious defects include, but are not restricted to, one or more of the following conditions:
(1) Excessive damage by an act of God, usually a weather event such as windstorm, lightning strike or flooding, with major broken branches, split trunk, large cracks or other defects that cannot be corrected by pruning.
(2) Severe cracks in the main stem or in branch unions that penetrate deeply into the wood of the tree.
(3) Advanced decay associated with cracks, branch unions, cavities in the tree or root flares and buttress roots. Evidence of fungal activity including mushrooms, conks, and brackets growing on root flares, stems, or branches can be indicators of advanced decay.
(4) Leaning beyond 45° from vertical with evidence of recent root exposure, soil movement or soil mounding.
(5) Supported solely by the action of another tree or object.
PROTECTED TREEAny of the following:
(1) A tree with a DBH of eight inches or more, regardless of location.
(2) A tree with a DBH of three inches or more located in a wetland, watercourse buffer or watershed buffer (as defined elsewhere in Village Code).
(3) A tree with a DBH of three inches or more located on a slope of 25% or greater.
(4) A tree that has been planted as a specific requirement of site development plan approval or as part of a previous replanting or restoration agreement.
(5) A tree of historic or unique value to the Village (as defined herein).
(6) A tree with a DBH of three inches or more designated by the New York State Department of Environmental Conservation as a protected native plant for our region.
PUBLIC PROTECTED TREEAny of the following:
(1) A tree with a DBH of eight inches or more located on lands owned by the Village or land upon which property rights such as easements are imposed for the benefit of the Village.
(2) A tree, regardless of size, planted in a designated tree well or curbside in the public right-of-way.
REPLANTING AGREEMENTA written agreement between the property owner and the Village specifying types and sizes of trees and/or shrubs to be planted as replacements for those that have been removed.
TREE FUNDA special purpose fund into which shall be deposited any penalties for violations or payments in lieu of restoration/replanting which shall be used at the discretion of the Village Board of Trustees to promote the intent and purpose of this section, including the purchase and maintenance of trees, shrubs, plants and green spaces. The Board of Trustees may request from, and/or consider a written recommendation initiated by, the Tree Commission as to the use of the funds. The Village Board of Trustees shall establish any fee or basis of payments in lieu of replanting and same shall be included in the master fee schedule and be revised in accordance with Chapter
175.
TREE OF HISTORIC OR UNIQUE VALUEA tree with unique or noteworthy characteristics or intrinsic value, including, but not limited to, species, age, location, historical significance, ecological value, or incomparable or irreplaceable aesthetic benefit to the community or environment. Examples include:
(1) "Champion" tree listed on an accredited tree registry or shown to be of comparable size to such listed tree.
(2) Rare or endangered species on federal or state lists.
(3) Specimen tree exhibiting qualities such as noteworthy leaf color or shape, peeling bark, floral display, fruit, overall form or habit, unique wildlife habitat support, or rarity.
TREE REMOVAL (TR) APPLICATIONA completed form entitled "Tree Removal Permit Application" available from the Building Department or the Village website, to be submitted by any party wishing to remove one or more protected trees as outlined herein.
TREE REMOVAL PERMITA permit approved and duly issued pursuant to the terms of this section. The permit consists of a written document in form determined by the Building Department acknowledging which trees have been approved for removal and is accompanied by a permit sign to be posted publicly. The permit may also include additional compliance requirements such as a replanting agreement or landscape plan.
TREE RISK ASSESSMENTA determination of the extent to which a tree is hazardous using an industry-wide rating scale taken from "A Photographic Guide to the Evaluation of Hazard Trees in Urban Areas" published by the International Society of Arboriculture. Risk is rated by evaluating the probability of failure of the tree, its size and the targets that could be damaged if it fails.
UTILITY DISTRIBUTION LINE VEGETATIVE MANAGEMENTThe procedure by which electrical utility companies manage potential or existing conflict between power lines and vegetation, thereby minimizing tree-related power outages. While most vegetative management involves tree trimming, trees that pose hazards to power lines because of ill health, proximity to the lines or other problems may be determined to be hazardous by the utility's arborist and be removed.
