Specifications include, but are not limited to: Snow Removal and plowing work will be accomplished in accordance with the following standards. Roads shall be plowed to maintain a minimum of two inches of snow so as not to damage the road surface. No snow removal shall occur unless there is a minimum of four to six inches of snow on the ground and snow is continuing to fall, or there have been successive two to three inch snowfalls and the depth of the snow in the parking area has reached four to six inches in depth. In the event the Contractor leaves an unsatisfactory surface, payments to the Contractor may be withheld. Snow, ice, and debris shall be removed from culverts and ditches so that the drainage system will function efficiently at all times. Banks shall not be undercut. Snow berms shall not be left on the road surface. Berms left on the shoulder of the road shall be removed and/or drainage holes shall be opened and maintained. Drainage holes shall be spaced as required to obtain satisfactory surface drainage without discharge on erodible fills. Work shall be performed in a manner to preserve and protect roads and roadside structures such as signs and culverts, to prevent erosion, and prevent damage to roads, streams and other Forest values. Road slopes shall not be undercut. Care shall be taken to ensure that gravel is not bladed off of road shoulders. Paved areas shall be plowed as clear as possible without damage to the paved surface. Snow removal standards shall be from ditch line to outside shoulder for the entire length. On two lane roads, snow removal must be sufficient to allow two vehicles to pass side by side. Work shall be performed in accordance with all landowner rules and regulations. Any damage to the underlying road surface or damage to roadside structures from plowing and removal work are the sole responsibility of the contractor to repair or replace, not the agency or the landowner.
