ATTACHMENT 2 <br />TREE PRUNING/TRIMMING & STUMP REMOVAL SPECIFICATION <br />TREE TRIMMING CLASSIFICATIONS <br />Class I — Fine Pruning /trimming <br />Fine pruning/trimming shall consist of the removal of dead, dying, diseased, interfering, objectionable, obstructing <br />and weak branches as well as selective thinning to lessen wind resistance. The removal of such described <br />branches is to include those on the main trunk, as well as those inside the leaf area. <br />Class II — Medium Pruning/trimming <br />Medium pruning/trimming shall consist of the removal of dead, dying, diseased, interfering, objectionable weak <br />branches on the main trunks as well as those within the leaf areas. An occasional branch up to one inch in <br />diameter may remain within the main leaf area where it is not practical to remove it. <br />Additions to the standard specifications: All girdling roots visible to the eye are to be reported to a supervisor <br />and /or the owner. <br />Class I II — Coarse Pruning /trimming <br />Coarse pruning/trimming shall consist of the removal of dead, diseased or obviously weak branches, two inches in <br />diameter or greater. <br />Class IV — Cutting Back or Drop Crotch Pruning /trimming <br />Cutting back or drop crotch pruning/trimming shall consist of the reduction of tops, sides, under branches or <br />individual limbs. This practice is to be undertaken in cases of utility line interference or where certain portions of <br />the roots or root systems have been severed or severely damaged, or when it is necessary to reduce the top, <br />sides, or under branches to achieve overall size reduction. <br />GENERAL TREE PRUNING/TRIMMING REQUIREMENT <br />1. All cuts shall be made sufficiently close to the trunk or parent limb, without cutting into the branch collar or <br />leaving a protruding stub, so that closure can readily start under nominal conditions. Clean cuts shall be <br />made at all times. <br />TYPES OF CUTS: <br />Removal of laterals <br />A. Shoulder cuts. The final cut in removing a lateral branch should be immediately beyond the <br />branch bark ridges, preserving the branch collar. Do not make stub cuts (an inch or more beyond <br />the branch collar). Do not make flush cuts (through the branch collar). <br />a. Triple cuts. For any branch too large to be held while being cut, remove by means of the <br />following cuts: <br />Undercut the branch 4 to 10 inches beyond the base (to prevent splitting or peeling). <br />
