This standard was developed under the procedures of the American National Standards Institute by Accredited Standards Committee on Tree, Shrub and Other Woody Plant Maintenance Operations, A300. The National Arborist Association is the secretariat of A300. Accredited Standards Committee A300 was approved June 28, 1991. The Committee was organized to develop a consensus performance standard for persons engaged in the maintenance of trees, shrubs and other woody plants. The Committee includes representatives from the residential and commercial tree care industry; the utility, municipal, and federal sectors; the landscape and nursery industries; as well as other interested organiza- tions. The A300 standard currently addresses tree pruning practices only. Subcommittees have been formed to address Construction Protection; Cabling, Bracing, and Guying; Soil Modification/Fertilization; Lightning Protection; Equipment Calibration; Tree Growth Regulators; and Shrub, Vine, and Other Woody Plant Pruning. - Specifications for tree work should be written and administered by an arborist. An arborist is a professional who possesses the technical compe- tence through experience and related training to provide for or supervise the management of trees and other woody plants in the residential, com- mercial, and public landscape. This A300 standard offers basic perfor- mance standards. It is not a guideline to illustrate how to prune trees. This standard has been drafted -to address pruning specification require- ments across all geographic areas. The users of this standard must inter- pret the wording based on their knowledge of the growth habits of certain tree species within a given environment. Suggestions for improvement of this standard should be forwarded to: A300 Secretariat, c/o National Arborist Association, P.O. Box 1094, Amherst, NH 03031. This standard was processed and approved for submittal to ANSI by Accredited Standards Committee on Tree, Shrub and Other Woody Plant Maintenance Ooerations, A300. Committee approval of the standard does not necessarily imply that all committee members voted for its approval.

Operations shall comply with applicable Occuoational Safety and Health Administration (OSHA) standards (see clause 2), ANSI Z133.1, as well as state and local regulations. 5 Tree pruning 5.1 Purpose The purpose of this clause is to provide speci- fications for tree pruning, 5.2 Pruning practices 5.2.1 Reasons for pruning The reasons for tree pruning may include, but are not limited to, reducing hazards, maintain- ing or improving tree health and structure, improving aesthetics, or satisfying a specific 4 need such as: removing diseased, dead, dying, decayed, interfering or obstructing branches; training young trees; utility line clearance; or specialty tasks as defined in this standard. Before pruning, the primary objec- tive should be clearly defined. That objective should be accomplished in the manner most beneficial to the health of the tree. Pruning practices for agricultural, horticultural production or slvicultural purposes are exempt from this standard. 5.2.2 When to prune To obtain the defined objective, the growth cycles of individual species as well as the type of pruning to be performed should be considered. 5.2.3 Tree inspection Before beginning work and while work is being performed, a qualified person shall visually inspect each tree. If a condition is observed that requires additional attention, this condi- tion should be brought to the attention of an immediate supervisor or the person responsi- ble for authorizing the work. 5.2.4 Tools and equipment 5.2.4.1 Pruning tools used in making pruning cuts shall be kept adequately sharpened to result in final cuts with a smooth surface and firmly attached remaining adjacent bark. 5.2.4.2 Hook and blade pruning tools should be used; not anvil -type pruning tools. 5.2.4.3 Climbing spurs should not be used when climbing trees, except as specified else- where in this standard. Climbing spur use is permissible on tree removals and in emergen- cies such as aerial rescue. 5.2.4.4 Equipment and work practices that damage bark, cambium, live palm tissue, or any combination of these, should be avoided. 5.2.5 Pruning cuts 5.2.5.1 A thinning cut should be the preferred type of cut to make. 5.2.5.2 A thinning cut shall consist of the removal of a lateral branch at its point of origin or the shortening of a branch or stem by cutting to a lateral large enough to assume the terminal role. 5.2.5.3 A heading cut should rarely be used on mature trees, yet may be appropriate for -ECG-1?oCZ specific purposes such as, tut nct limited to, training young trees: pollarding, shaping termi- nal flowering trees, storm damage repair, etc. 5.2.5.4 A heading cut should consist cf cut- ting a currently growing or one -year -old shoot back to a bud, or cutting an older branch cr stem back to a stub or lateral branch not sufficiently large enough to assume the terminal role. 5.2.5.5 When removing a lateral branch at its point of origin on the trunk or parent limb, the final cut shall be made in branch tissue close to the trunk or parent limb, without cutting into the branch bark ridge -or collar, or leaving a stub. (See figure 1.) 5.2.5.6 When removing a leader or length of a branch, the angle of the cut should bisect the angle between the branch bark ridge and an. imaginary line perpendicular to the leader being removed. (See figure 2.) - 5.2.5.7 When removing a dead branch, the final cut shall be made just outside the collar of live tissue. If the collar has grown out along the branch stub, only the dead stub should be removed. The live collar shall remain intact and uninjured. 5.2.5.8 To prevent damage to the parent limb when removing a branch with a narrow branch attachment, the final cut should be made from the bottom of the branch up. (See figure 3.) 5.2.5.9 Cut limbs shall be removed from the crown upon completion of the pruning, or at times when the tree would be left unattended or at the end of the work day. Wound treatment 5.2.6.1 Wound dressings and tree paints should not be used to cover pruning wounds, except when specified for disease, borer, mistle- toe, sprout control, or cosmetic reasons. If wound dressings or paints are used for cosmetic or other reasons, then materials nontoxic to the cambium layer shall, be used, and only a light coating shall be applied to the wound surface. 5.2.6.2 When repairing bark wounds, only damaged or loose bark should be removed, disturbing a minimal amount of live tissue. 5.2.6.3 Cavities shall not be filled or treated if the boundary reaction zones would be disturbed. 5.3 Mature tree pruning 5.3.1 General The following specifications should be used with pruning objectives. 5.3.1.1 Pruning cuts shalt be made in accor- dance with 5.2.5. 5.3.1.2 Tree branches shall be removed in such a manner so as not to cause damage to other parts of the tree or to other plants or property. Branches too large to support with one hand shall be precut to avoid splitting or tearing of the bark. (See figure 1.) Where nec- essary, ropes or other equipment should be used to lower large branches or portions of branches to the ground. 5.3.1.3 When a branch is cut back to a lateral, not more than one-fourth of its leaf surface should be removed. The lateral remaining should be large enough to assume the terminal role. 5.3.1.4 Not more than one-fourth of the foliage on a mature tree should be removed within a growing season. 5.3.1.5 Upon completion of pruning a mature tree, one-half of the foliage should remain evenly distributed in the lower two-thirds of the crown and individual limbs. 5.3.2 Size specifications A minimum or maximum diameter of branches to be removed should be specified to establish the extent of pruning, such as: the removal of branches 3 in (7.5 cm) in diameter and greater, or; the removal of branches 2 in (5 cm) in diameter and greater, etc.' 5.3.3 Pruning objectives Pruning objectives should be established prior to beginning any pruning Operation. 5.3.3.1 Hazard reduction pruning Hazard reduction pruning is recommended when the primary objective is to reduce the danger to a specific target caused by visibly defined hazards in a tree. Hazard reduction pruning should consist of one or more of the maintenance pruning types. 5.3.3.2 Maintenance pruning Maintenance pruning is recommended when the primary objective is to maintain or improve tree M r ANStA300-1995 s s $dC :nC First Cut ---_ _ .• Final OA Bfznch G�dar Bark fudge - — � I Figure 1 — Removing a large lateral branch requires two preliminary cuts before the -final cut am FinalC,ut Figure 2 — When cutting back to a lateral, Figure 3 - When removing a branch with a bisect the angle between the branch bark narrow branch attachment, cut from the bottom ridge and an imaginary line perpendicular to the leader or the branch being removed upward C jQZ health and structure, and ir=u,:as hazard reduc- ticn pruning. Maintenance pruning should consist of one or more of the ccllcwirg pruning types: a) Crown cleaning: Crown cleaning shall consist of the selective removal of one or more of the following :terns: dead, dying, diseased, weak branches and watersprouts from a tree's crown; b) Crown thinning: Crcwn thinning shall consist of the selective removal of branches to increase light penetration, air movement, and reduce weight; c) Crown raising: Crown raising shall con- sist of the removal of the lower branches of a tree in order to provide c!earance; d) Crown reduction (crown shaping): Crown reduction reduces the height and/or spread of a tree. Consideration should be given to the ability of a species to sustain this type of pruning; e) Vista pruning: Vista pruning is selective thinning of framework limbs or specific areas of the crown to allow a specific view of an object from a predetermined point; f) Crown restoration: Crown restoration prun- ing should improve the structure, form, and appearance of trees that have been severely headed, vandalized, or storm damaged. 5.4 Young tree pruning 5.4.1 At planting When a young tree is planted, dead, broken, and split branches should be removed. A cen- tral trunk or leader or well -spaced multiple trunks or leaders "(as most appropriate for the species and specimen) should be developed by removing competing leaders and removing, heading, or thinning laterals on vigorously growing branches that compete with the selected leader(s). Branches should be retained on the lower trunk to increase taper. 5.4.2 During the first three years after planting A strong scaffold branch structure should be developed by selecting the primary scaffold branches. To improve the scaffold structure, branches that are crossing, have included bark, or interfere with the scaffold branches should be removed. Scaffold branches should be properly spaced. For deciduous shade trees that will reach or exceed 40 ;t (; ? m) in height at maturity, the recornmerdec soacing between primary scaffold branches is accroxi- mately 18 in (46 crn). For smaller species, 6 to 8 in (15 to 20 cm) would be adequate. 5.4.3 Between four and six years after planting The development of a good, structurally sound scaffold branch system should be continued by selective thinning of or on branches and removing dead, interfering, split, and broken branches. Large -growing branches with narrow angles of attachment shall be removed from the trunk or canopy. Lower branches shall be pruned (crown raising) so as not to interfere with human needs where appropriate. 5.5 Specialty training systems 5.5.1 Espalier Espalier pruning is a combination of cutting and training branches that are oriented in one plane; formally or informally arranged; and usually supported on a wall, fence, or trellis. The patterns can be simple or complex but the cutting and training is precise. Ties should be replaced every. few years to prevent girdling the branches at the attachment site. 5.5.2 Potlarding Pollarding_is a training system used on some large -growing deciduous trees that are severely headed annually or every few years to hold them to modest size or to give them and the landscape a formal appearance. PoNarding'is not synonymous with topping, lopping, or stubbing. Pollarding is severely heading some and removing the other vigor- ous water sprouts back to a definite head or knob of latent buds at the branch ends. 5.6 Palmpruning 5.6.1 Palm pruningshouldbe performed when fronds, fruit, or loose petioles may cre- ate a dangerous condition. 5.6.1.1 Live healthy fronds, initiating at an angle of 45° or greater from the horizontal plane, should not be removed. 5.6.1.2 Fronds removed should be severed close to the petiole base without damaging liv- ing trunk tissue. 7 ANSI A300-1995 5.6.1.3 Palm peeling (shaving) should ccn- sist of the removal of the dead frond bases only, at the point they make c0ntac: with t~e trunk without damaging living trunk tissue. 5.7 Utility pruning 5.7.1 General The purpose of utility pruning is to remove branches in order to prevent the loss of ser- vice, prevent damage to equipment, avoid impairment and uphold the intended usage of the facility/utility space. 5.7.1.1 Only a qualified line clearance tree trimmer or qualified line clearance tree trim- mer trainee should be assigned to line clear- ance work in accordance with ANSI Z133.1, 29 CFR 1910.331 — 335, 29 CFR 1910.268, or 29 CFR 1910.269. 5.7.1.2 Utility pruning operations are exempt from requirements in 5.2.3. 5.7.2 Utility crown reduction pruning 5.7.2.1 Urban/residential environment 5.7.2.1.1 Cuts should be made in accordance with 5.2.5 and 5.2.6. 5.7.2.1.2 A minimum number of cuts should be made to accomplish the purpose of facili- ty/utility pruning. The natural shape of the tree should be considered. 5.7.2.1.3 Trees directly under and growing into the facility/utility should be removed or pruned. Such pruning should be done by removing entire branches or by removing branches that have laterals growing; into (or, once pn.ned, will grow into) the facility/utility space. 5.7.2.1.4 Trees growing along the side and growing into or toward the facility/utility space should be pruned by removing entire branch- . ° , es. Branches that.. when cut. will produce sprouts that would grow into facilities and/or utility space should be removed. 5.7.2.1.5 Branches should be cut to laterals or the parent branch and not at a preestab- lished clearing limit. 5.7.2.2 Remote/rural environment 5.7.2.2.1 Climbing spurs Climbing spurs may be used when limbs are more than throw line distance apart, or when the bark is thick enough to prevent damage to the cambium, or there are no other practical means of climbing the tree. 5.7.2.2.2 Remote locations Utilities must often maintain facilities/corridors at remote locations. In such locations, it may be appropriate to use mechanical pruning equipment. 5.7.2.2.3 Mechanical pruning Cuts should be made close to the main stem, outside of the branch bark ridge and branch collar. Precautions should be taken to avoid stripping or tearing of bark or excessive wounding. 5.7.3 Emergency service restoration During a utility declared emergency, utilities must restore service as quickly as possible in accordance with ANSI Z133.1 29 CFR 1910.331 — 335, 29 CFR1910.268, or 29 CFR 1910.269. At such times it may be necessary, because of safety and the urgency of.service restoration: to deviate from the useof proper pruning techniques as defined in this stan- dard. Following the emergency, corrective pruning should be done as necessary.

Attachment cc: City Administrator WOWWDoc=-ft'm—Vn-0$'FadkyEq*n-LMmForestMerwgemaxSWAM CbC �r • To: Bruce Malkenhorst, G1/ dministrator From: Samuel Kevin Wilson, Director of Community Services and Water RE: Tree Trimming Cost Comparisons Date: April 8, 2002 The Department of Community Services and Water is requesting authorization to seek proposals to contract out the City's tree trimming services. In a recent cost comparison analysis using West Coast Arborists as a bench mark, it was determined that it would be significantly more cost-effective for the City to contract its tee trimming services rather than have City crewmembers continue to perform this task. The following is a cost comparison of trimming existing City trees by the City of Vernon versus contracting these services out to West Coast Arborists, Inc. Please keep in mind that the actual number of trees is an approximation and not an actual number. Additionally, the amount of time spent by the City crew trimming these trees is based on the average size and the species of each tree.
