3.1Clearing and Grubbing.

3.1.1 No trees shall be cut until designated by the Engineer. Particular reference is made to fruit, ornamental or shade trees or plants at the edge of the roadside slopes. Cut or scarred surfaces of trees or shrubs selected for retention shall be pai nted with an approved wound dressing or treated according to other accepted arboricultural practices. 3.1.1.1 The Contractor may be required to file an intent to cut and shall pay all charges, fees, and taxes as may be required under Chapter 79 of the RSA. 3.1.2 All trees ordered to be cut shall become the property of and shall be disposed o f by the Contractor, except as provided hereinafter. In the interest of energy and material conservation, the Contractor shall salvage wood from cut trees in accordance with standard commercial logging practices. 3.1.3 Unless otherwise shown on the plans, clearing and grubbing shall extend 10 ft. beyond areas of excavation and 5 ft. beyond embankment slopes. 3.1.4 The Contractor shall perform the work of clearing and grubbing to include the removal of only the materials specified herein. In order to conserve topsoil, rake teeth on bulldozers shall be used when removing stumps and brush unless other equipment is permitted. 3.1.5 Except in areas designated to be excavated, any excavation caused by the grubbing operations shall be filled with suitable material and compacted to conform to the surrounding ground. 3.1.6 All stumps and large roots within the limits of the roadbed shall be completely rem oved to a depth of 3 ft. below subgrade unless a greater or lesser depth is specified on the plans. Stumps wit hin the limits of the roadbed below such depth and stumps under embankments or outside the roadbed shall be cut off within 6” of the existing ground surface except in the area to be rounded at the top of backslopes, where stumps are to be cut off flush wit h the surface of the final slope line or removed at the Contractor’s option. 3.1.6.1 When stumps are designated to be removed by grinding, the Contractor shall use an approved stump -grinding machine such that no damage occurs to surrounding structures. 3.1.7 All stumps, roots, branches, brush, weeds, and other perishable material resulting from the clearing and grubbing operations shall be disposed of by an approved method. The Contractor 's attention is directed to RSA 149- M regarding the fact that stumps and roots from grubbing operations are classified as solid waste. As such, these stumps shall be disposed of in permitted sites, through firms having facilities to convert the stumps to marketable products, or by grinding or chipping. Permits for sites are obtained from the New Hampshire Department of Environmental Services, Division of Waste Management. It is the responsibility of the person disposing of the stumps to obtain all the necessary permits and to comply with the New Hampshire Solid Waste Rules and Design Standards in effect at the time of disposal.

New Hampshire Department of Transportation Standard Specifications – 2016 3.1.7.1 All wood less than 5” in diameter and not cut into 4 ft. lengths for firewood shall be chipped. Burying of brush will not be permitted. Stumps, roots, and rotten wood may be buried at approved sites on or off the project. Approved sites shall have a minimum of 24” of cover material and shall be graded and shaped as directed by the Engineer. If burial is to be on private land, the agreements as to how the area is to be left shall be set fo rth on the Disposal Agreement form provided by the Department in accordance with 106.10. Three signed copies of the Disposal Agreement shall be furnished to the Engineer. Approval of the proposed disposal area will be contingent upon agreement by the Contractor and the property owner to leave the area in such shape that it blends with the surrounding terrain and that erosion is kept to a minimum. Without special permission, slopes shall not be left steeper than 3:1 (horizontal to vertical). No disposal area shall be left in such condition that erosion, after completion of the work, might result in water pollution by silt or other deleterious substances. Areas shall be left in such shape and condition that material does not wash and block or obstruct drainage ways. If holes caused by settlement appear, they shall be filled as directed. A release from the property owner is required prior to final project acceptance. 3.1.7.2 Except in the case where wood is piled neatly for future use, storage locations should be outside the limits of view from the project, other highways, and residences. 3.1.7.3 When ordered, available chipped material shall be stockpiled in the quantity directed to be used for erosion control. The Contractor may market any remaining chips or dispose of them by other approved methods. 3.1.7.4 Unless otherwise ordered, disposal areas shall be covered with material capable of supporting vegetation and either fertilized and seeded with grass seed or planted with seedlings. Seedlings shall be set out in accordance with accepted horticultural practices as directed in the agreement. 3.1.7.5 Unless permission is given to preserve access roads to disposal areas adjacent to highways, such access roads shall be obliterated. 3.1.8 When fence lines go through wooded areas, a strip 3 ft. wide shall be cleared for the fence line.

3.2Roadside Cleanup.

3.2.1 Roadside cleanup of leaning, dead, unsound, and unsightly trees, branches, stubs, refuse, and slash (material remaining after logging operations), generally to a limit of approximately 15 ft. outside the limits specified in 3.1.3 above, shall be performed where and as directed. The material shall be disposed of as provided in 3.1. This work will not ordinarily be required outside of the right-of-way lines, but the Engineer may order that portions of medians or entire medians be cleaned up under this Section. All tree trimming in connection with roadside cleanup shall be done in accordance with accepted tree surgery practices.

3.3Trimming of Trees.

3.3.1 On trees or shrubs designated to remain, low hanging, unsound, or unsightly branches shall be removed as directed. Branches of trees extending over the roadbed shall be trimmed to g ive a clear height of 20 ft. above the roadbed surface. All trimming shall be done in accordance with accepted tree surgery practices.

3.4Invasive Species.

3.4.1 Statutory authority of RSA 430:55, the NH Department of Agriculture, Markets, and Foods prohibits the spread of invasive plants listed in Table 3800.1 of Part AGR 3800. Follow best management practices (BMPs) to avoid spreading these plants to new sites.
