Excavation: When conditions detrimental to plant growth are encountered, such rubble fill,adverse drainage conditions, or obstructions, notify Architect before planting.C. Adjacent Landscape: Protect planted areas adjacent to construction area. Replace orrecondition to prior conditions at project completion.D. Tree Protection:1.Existing trees to remain should be protected before any site/demolition Tree protectionarea is defined as the area within the drip line diameter.2.Place protective fencing around a tree protection zone. Protective fencing shouldconsist of a highly visible, physical barrier (a minimum 6-foot high, chain-link fence isrecommended) to be placed 10 ft outside the dripline of the tree(s).3.Do not strip topsoil or grub under story within protection area. The tree under story tobe removed shall be cut instead of pulling or grubbing. Leave the soil undisturbed.4.Prohibit earth stockpiling, material storage, vehicle parking and traffic within treeprotection area.5.Prohibit dumping of refuse, chemicals, other materials and puddling or running waterthat may injure tree growth.6.Prohibit cutting, breaking and skinning of branches and roots. All pruning of branchesand roots is to be performed by the Arborist.7.Prohibit skinning and bruising of bark.8.No changes in grade should be made within the dripline of existing trees.9.Temporary irrigation is highly recommended for all remaining trees during construction.This system should provide adequate coverage and quantity of water during all phasesof construction.10.Before the contractor leaves the site, all existing trees which have been damaged dueto construction should be repaired/replaced at the expense of the contractor.E. Excavation Around Trees:1.Where trenching is required in the vicinity of the tree, proceed as follows:a. As the trench approaches the drip line of the tree, dig by hand until the rootsencountered are two inches or larger in diameter.b. A similar trench is to be dug on the opposite of the tree and a tunnel augured underthe tree between the two trenches at a depth of 4 feet.c. If auguring is impractical, continue digging by hand. Carefully dig under any rootsover 4 inches in diameter. Do not cut main lateral roots or tap roots.2.Where excavating for new construction is required in soil containing the roots of thetree, hand excavate to minimize damage to root system. Use narrow tine spading forksand comb soil to expose roots. Relocate roots back into backfill areas whereverpossible. If large main lateral roots are encountered, expose beyond excavation limitsas required to bend and relocate without breaking.3.If root relocation is not practical, cut roots approximately 3 inches back from newconstruction.4.Any digging or cutting that tears roots or disturbs soil beyond the grading limit isunacceptable. All roots larger than one inch must be cut by the Arborist.5.Do not allow exposed roots to dry before permanent backfill is placed; providetemporary support and protect roots against damage until permanently relocated andcovered with backfill.F. Construction Pruning:1.Hire an Arborist certified by the International Society of Arboriculture. Where roots havebeen cut, Arborist shall prune the tree to compensate for root loss and prune any lowlimbs which may interfere with construction activities. Compensate in approximate directproportion to root loss. Do not use any sort of paint or dressing on wounds or pruningcuts. Root pruned and construction pruned tree shall be fertilized by the landscapecontractor by broadcasting sulfur coated area 38-0-0 at the rate of 5 1/4 lbs. Per 1,000square feet (2 lbs. N.) Over the root zones of the trees. P A R T 3 - E X E C U T I O N 3 . 1 P R E P A R A T I O N - G E N E R A L A .
