EARTHWORK – CLEARING AND GRUBBING
1. Construction
Clear and grub all surface objects, vegetation, trees, stumps, roots, and other debris designated for removal. Mow as required. Undisturbed and sound stumps and nonperishable solid objects more than 3 ft (1 m) below subgrade and embankment slopes may remain in place. Stumps and nonperishable solid objects that extend less than 3 in. (75 mm) above the ground line or low water level may remain if they are outside excavation and embankment areas. Cut stumps flush with or below the final slope line. Preserve trees, shrubs, plants, and other objects designated to remain.
Dispose of material and debris. Disposable material and debris may be disposed of by burial at designated locations with at least 12 in. (300 mm) of cover material. Obtain written arrangements with property owners and governmental authorities for disposal locations outside the right-of-way limits.
Remove low-hanging and unsound branches from remaining trees or shrubs. Use proper tree surgery practices to trim tree branches. Trim branches of trees extending over the roadbed to provide a clear height of at least 20 ft (6 m). Seal the cut or scarred tree or shrub surfaces with an asphaltum base paint made for tree surgery.
