C. Cover exposed roots within four (4) hours to reduce damage caused by desiccation. Roots may be covered with soil, mulch, polyethylene, or wet burlap to help protect them from drying.

D. Designate limited areas as concrete washout areas. Locate concrete washout areas away from root zones.

3.02 TREE PROTECTION FENCING, if specified on the Drawings

A. Install tree protection fencing around each tree to be preserved as indicated in the tree treatment schedule and on the tree protection plan.

1. Each tree to be preserved shall be protected with a tree protection fence. The fencing shall be continuous between posts, shall be pulled taut prior to securing to posts, and shall be firmly attached to the posts with a minimum of 4 wire ties.

2. The fencing shall be located three (3) feet outside of the tree, or group of trees, drip line or as indicated on the drawings.

3. All tree protection fencing shall be installed prior to site work or construction activity. The fence shall be placed in a continuous alignment as shown on the tree protection plan. Fences shown on tree protection plan are drawn to scale and shall be installed as drawn, in the field.

In general fences shall be placed 30” back of existing curb or edge of pavement where root pruning or zero curb cutback is not specified, and 6” back of root pruning trench where root pruning is specified and immediately back of curb where zero curb cutback is specified. Exact locations shall be approved by the project urban forester and/or engineer in the field. The Fences shall be placed to protect roots, trunks, and foliage. The contractor shall not remove or relocate tree protection fencing and shall not operate within the limits shown without direct approval of the project urban forester. In areas where the proposed waterline is located in the existing roadside ditch and where tree protection fencing cannot be installed across the ditch, the fencing shall be installed at the top of outside ditch bank and no bore pits, peep holes, service taps, or any excavation should occur in the area immediately in front of the tree protection fencing for trees called out with “bore” in the Tree Treatment Schedule. The “bore” limits shall be the same as the limits of the tree protection fencing.

4. Storage of equipment or materials will not be allowed inside a fence. Entryways and access into a protected area shall not be provided unless approved by the project urban forester.

5. Damage to tree fences occurring during the progress of the work shall be repaired immediately at no additional cost to owner. Workmen shall be clearly instructed to exercise caution in performance of work near trees being preserved.

6. Tree protection fencing shall be removed by contractor, at no additional costs, upon completion of all construction activity in each work zone area. Tree protection fencing materials used in the first two work zone areas shall be removed and utilized in subsequent work zone areas.

Materials and labor shall be paid for each linear foot of fencing installed in first two work areas. All fencing installed in subsequent work zone areas shall be paid for labor only.

7. Prohibited activities within tree protection fencing

a) Storage or parking of vehicles and/or construction equipment

b) Storage of construction materials of any type including, but not limited to petroleum products, concrete mixes, dirty water, lime, and gravel.

c) Storage of excavation spoils and/or fill materials.

d) Construction spoils including, but not limited to concrete washout, paint thinners and excess petroleum products, lime, or any other material which may be deleterious to the trees.

e) Cutting of tree roots due to utility trenching, digging, placement of curbs or other construction activities.

f) Any soil disturbance due to stripping existing topsoil or added fill soil

g) Use of trees as support posts, anchorage, power poles, or signposts; anchorage for ropes, guy wires, or power lines; or other similar functions either permanent or temporary.

h) Damage to trunk, limbs, or foliage caused by maneuvering vehicles or stacking material or equipment too close to the tree.

i) Excessive water or heat from equipment, utility line construction, or burning of trash under or near bushes or trees.

j) Damage to root system from flooding, erosion, puddling or continuous running water, and excessive wetting and drying resulting from dewatering and other operations.

k) Skinning or bruising of bark.

3.03 PRUNING OF TREES

A. Trees shall be pruned in accordance with the American National Standard for tree pruning, ANSI A300 (Part 1) – 2001 Pruning Revision of ANSI A300-1995 Tree, Shrub and Other Woody Plant Maintenance – Standard Practices. Pruning shall be completed by professional arborists who has received training in proper pruning techniques.

C. Clearance prune designated trees for public streets, sidewalks, and construction areas. Provide minimum 14 feet and maximum of 18 feet of vertical clearance over proposed water trunk lines. Provide minimum of 14 feet and maximum of 16 feet of vertical clearance over proposed street construction, from 24” back of curb on one side to 24” back of curb on the other side. Provide 20’ of vertical clearance over proposed storm sewer up to 38” in size, and 30’ of vertical clearance for storm sewer larger than 38” in size. Pruning to be installed prior to any construction activity. Contractor shall notify property owner prior to trimming or pruning any trees with trunks located on private property.

D. All cuts should be made sufficiently close to the parent limb or trunk without cutting into the branch collar or leaving a protruding stub, so that closure can readily start under normal conditions. All lateral cuts shall be made to a lateral that is least 1/3 the diameter of the parent limb. Clean cuts shall be always be made.

E. Trees shall be pruned in a manner that will not destroy or alter the natural shape and character of the tree. Apply black latex paint to all fresh wounds on Oak (Quercus) species immediately after each cut is made.

F. Crown cleaning prune designated trees shall include selective removal of dead, diseased, and/or broken limbs.

3.04 TREE REMOVAL

A. Trees scheduled for removal shall be sawed down and debris hauled from the site the same day. The stump shall be ground to twelve (12) inches below grade and excess grindings shall be hauled from the site the same day, so that a pile of grindings is not left where the stump was ground. Enough grindings should be left so that an open hole does not remain.

B. The Contractor shall notify the Project arborist or Owner Engineer immediately if the Contractor has identified a dead and damaged tree(s) that was not previously identified on the Drawings. The Contractor shall provide a station and offset dimension, or other appropriate means of locating the tree(s) location and the reason for the proposed removal. The Project Arborist shall decide as to the potential of restoration of the tree(s) to normal growth pattern shall be removed.

3.05 GRADING AND FILLING AROUND TREES

A. Maintain existing grade within the dripline of trees, unless otherwise indicated.

B. Where existing grade around trees is above new finish grade, under supervision of project urban forester, carefully hand excavate within the dripline to make transition to new finish grade.

C. Where existing grade is below new finish grade, place clean bank sand in a single layer to make the transition to new grade. Do not compact; hand grade to required elevation.

Specifically, to areas where proposed curb is higher than existing and backfill will be required.
