Such devices shall be functional before upland land-disturbing activities take place. The surface area of earthen material exposed by grubbing, stripping topsoil, or excavation shall be limited to that necessary to perform the next operation within a given area. The Contractor shall confine the grubbing of root mat and stumps to that area of land on which the Contractor shall perform excavation or other land disturbance activities within 14 days following grubbing operations. The Contractor shall remove stumps, roots, other perishable material, and nonperishable objects that will be less than 5 feet below the top of earthwork within the area directly beneath the roadway pavement and shoulders. Material and objects that will be 5 feet or more below the top of earthwork within the area directly beneath the roadway pavement and shoulders and all such material and objects beneath slopes of embankments shall be left in place unless removal is necessary for installation of a structure. The top of stumps left in place shall not be more than 6 inches above the surface of existing ground or low water level. Branches of trees that overhang the roadway, reduce sight distance, or are less than 20 feet above the elevation of the finished grade shall be trimmed using approved tree surgery practices in accordance with Section 601.03(b). Vegetation, structures, or other items located outside the construction limits shall not be damaged. Trees and shrubs in ungraded areas shall not be cut or trimmed without the approval of the Engineer. The Contractor shall dispose of combustible cleared and grubbed material in accordance with the following:

The Contractor shall leave no more than 2 feet of trunk attached to grubbed stumps. When specified in the Contract or directed by the Engineer that trees or other timber is to be reserved for the property owner, such material shall be cut in the lengths specified and piled where designated, either within the limits of the right of way, or not more than 100 feet from the right-of- way line. When not reserved for the property owner, such material shall become the property of the Contractor.301.02
