mm) below the original surface level of the ground in areas indicated to be grubbed and in areas indicated as construction areas under this contract, such as areas for buildings, and areas to be paved. Depressions made by grubbing shall be filled with suitable material and compacted to make the surface conform with the original adjacent surface of the ground.

B. Low Embankment Areas: When the finished subgrade is less than 3 feet (1 m) above the original ground, remove stumps, roots, and debris to a minimum of 6 inches (150 mm) below the original ground. Backfill stump and root holes with approved material and compact before placing embankment material.

C. High Embankment Areas: When the finished subgrade is 3 feet (1 m) or more from the original ground, stumps may be cut flush and left in place. Removal of undisturbed stumps and roots and nonperishable solid objects will not be required. The surface of the original ground shall be scarified before starting the embankment operation.

Valve sets may be up to 8-inch diameter.

R. Strip 6 inches of topsoil from a 10-foot radius around the well head and store in a pile adjacent to the work site for final reclamation. Excavate around the well casing to a depth adequate to cut and cap the well casing a minimum of 3 feet below ground surface.

S. Contractor shall supply and erect identification markers on all wells in this contract.
