a) 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. b) 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. c) 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.
