This work shall also include preservation from injury or defacement o f all vegetation and objects to remain.
201.2 -MATERIALS : Asphaltum base paint for tree surgery shall conform to the requirements of Section 715.36.
CONSTRUCTION METHODS
201.3 -GENERAL : The Engineer will designate the trees, shrubs, plants and other items to remain. All items designated to remain shall be preserved by the Contractor. All alignment stakes, grade stakes, guard stakes, boundary markers, bench marks, and tie points disturbed shall be replaced at Contractor expense and preserved until such time as their usefulness has ceased and permission for their destruction is given by the Engineer.
201.4 -CLEARING : Areas indicated on the Plans, and borrow and waste sites furnished by the Division, shall be cleared of the obstructio ns described. In areas where the proposed embankment is to be three
ground as is practicable but not to exceed six (6) inches above the ground surface at the base of the stumps. When stumps are located in the area of the backslope rounding of cut sections, they are to be cut flush with or below the final slope line. Areas where the proposed embankment is to be less than three ( 3) feet shall be treated as prescribed in Subsection 201.6. All merchantable timber and wood in the clearing area, except trees designated to remain, which has not been removed from the right -of-way prior to the letting date shall become the prope rty of the Contractor, unless otherwise provided. Unsound and low -hanging branches from remaining trees and shrubs, shall be removed as directed. Branches of trees extending over the roadbed shall be trimmed to give a clear height of at least twenty ( 20) feet above the road and shoulder pavement surface. All trimming shall be done with proper tree surgery practices. In all areas where stumps and shrubs are to remain, the surface of the ground shall not be unduly disturbed or compacted. Existing ground cover shall be preserved insofar as possible, and the area shall be left neat and clear and in a condition which is reasonably consistent with the surroundings. All abandoned utility poles within the limits of the right -of-way shall be removed and dispose d of by the Contractor. The removal shall be treated in a similar manner as the clearing and grubbing of trees. The poles to be abandoned will be marked by the Project Engineer.
96 201.5 -SELECTIVE CLEARING AND THINNING : Selective clearing and thinning areas will be designated on the plans. In order that the trees may be properly marked in advance of thinning operations, the Contractor shall give the Engineer at least two weeks’ notice pri or to starting work or prior to resuming work after suspending operations. Trees or bushes not designated to remain shall be cut. In no event shall selective clearing and thinning operations begin until the Engineer has given approval. All dead or disea sed trees or shrubs, junk, trash, litter, or foreign matter of any kind shall be removed from the areas to be treated. This shall include uprooted stumps and all branches, tops, trunks, and dead wood resulting from woodcutting operations or from any other causes. Trees and shrubs to be preserved shall be carefully pruned to remove all dead wood and diseased or injured tops or branches. In addition, in certain areas the Engineer may require the branches of designated trees to be removed to a height of twenty (20) feet above ground as directed in order to improve sight distance, provide head clearance, open vistas, or improve appearance of the tree. Complete clearing may be required in certain areas for the purpose of removing shade hazards, improving sigh t distances, or improving appearance. Such clearing shall be included under this Section. The Contractor shall avoid disturbing or compacting the existing ground surface, as well as avoid damage to plant growth. The use of tractors, cranes, winches, or any other heavy equipment, operating anywhere within the area to be selectively thinned, will not be allowed unless exceptions are specifically authorized. Any injury to trees and shrubs which are to be preserved shall be carefully repaired. Disturbed ground surface shall be restored as nearly as possible to natural condition. All pruning and repair to live trees and shrubs shall be done by skilled workers according to approved arboricultural practice. All pruning scars and all cuts and woun ds one ( 1) inch in diameter or over shall be painted with an asphaltum base paint. The Engineer may permit such cuts on evergreen trees to remain unpainted. All stumps, new or old, shall be cut to a maximum height of six (6) inches above the surrounding ground or as directed by the Engineer. Undesirable trees leaning or falling over the highway right -of-way from outside shall be cut at the property line.
201.6 -GRUBBING : In areas where embankments are to be c onstructed less than three ( 3) feet in depth, measured below the subgrade, complete grubbing of all trees, stumps, roots, bushes or hedge fences shall be accomplished. In areas where embankments are to be constructed three ( 3) feet or more in depth, measu red below the subgrade, stumps which have not been loosened by clearing and grubbing operations, and nonperishable solid objects, need not be grubbed or removed provided they are cut off as close to ground as practical but not greater than one ( 1) foot above the original ground surface. Near the toe of embankment slopes, remove all stumps to a depth of at least one ( 1) foot beneath the embankment slope surface. In areas not included within construction limits or selective clearing areas, all stum ps shall either be grubbed or cut flush with or below the original ground line. Brush, shrubs, down timber, rotten wood, rubbish and other objectionable objects and vegetation shall be cleared flush with the ground. Such areas will be clearly indicated o n the Plans.
97 201.7 -DISPOSAL : All wood, trash, debris, stumps, and other foreign matter shall be removed and disposed of by the Contractor. Material may be disposed of at approved waste areas or in accordance with the provisions prescribed. Non -combustible material may be disposed of in embankments in accordance with the applicable provisions. All burning of vegetative material shall be done in accordance with the applicable laws, ordinances, regulations, and requires an approval from the West Virginia Department of Environmental Protection, Division of Air Quality (DEP) as defined in the Code of State Rules, Title 45, Series 6. If the Contractor plans to burn during Forest Fire Season (March 1 -May 31 and October 1 -December 31) a permit is also required from the West Virginia Division of Forestry (No permit from the West Virginia Division of Forestry is required for burning between 4:00PM and before nightfall during Forest Fire Season). Copies of these approvals and permits are to be provided to the Engineer. Open burning shall be extinguished prior to nightfall unless previously approved by DEP, Division of Air Quality. It is the intent of this Specification that the health, safety, comfort, and the propert y of persons in the vicinity are protected from the effects of such burning. Open burning of Construction/Demolition Waste as defined in Section 207.6.5 will not be allowed. The disposal of Construction/Demolition Waste Materials shall be in accordance w ith Section 207.6.5. Clearing and grubbing materials (vegetative material only) shall be disposed of by chipping or burning using a pit burner/air curtain. Vegetative material may also be used in conjunction with erosion and sediment control features. If the Contractor chooses the chipping option, vegetative material may be reduced to chips of a maximum size of 2 inch. The chips may be disposed of in areas where erosion control is required, as a substitute for straw mulch in accordance with the applicable provisions of 642 and 652, or between slope lines and right -of-way lines in areas/locations as determined by the Engineer. When the pit burner/air curtain method of disposing of vegetative material is utilized, the Contractor will have two options. The first being an above ground fire box. If this option is chosen, the Contractor shall follow the manufacturer’s recommendations. The second option is an in ground trench. If this option is chosen, the Contractor shall construct a minimum trench of twenty (20) feet in length X ten (10) feet wide X ten (10) feet deep with vertical walls. The air curtain shall be sufficient that post burn vegetated material will be no larger than six (6) inches in any direction. The air curtain shall have a flow of air in order to prevent continuous smoke pillars from escaping the trench. The in ground trench is to be placed outside the roadway prism, unless otherwise approved by the Engineer. If the trenches are not to be eliminated in the subsequent excavation operation , they shall be backfilled. All backfill within the roadway prism shall be accomplished in accordance with the requirements of Section 207. Compaction of backfill outside the roadway prism shall be performed so as to obtain a minimum density equal to tha t of the surrounding ground. The prevailing winds during open burning should be away from any roadway, airport, city, or occupied residence likely to be affected by the smoke to the best extent possible. Open burning of vegetative material shall not be al lowed during periods of air stagnation advisories or alerts. The Contractor will be held responsible for any damage caused by fires. The Contractor shall remove and dispose of burned material; replace trees, shrubs, fences or other objects designated or described to remain, but which have been damaged; and seed burned areas beyond construction limits; all in an acceptable manner. Upon completion of the work, nothing shall remain within the right -of-way limits, nor along the land adjacent thereto, which was deposited by
98 the Contractor as the result of any of the operations of construction unless approved by the Engineer.
