Specifications include, but are not limited to: Snow Removal and plowing work will be accomplished in accordance with the following standards, and as stated in Parks Operating Procedure # 85-08 Snow Removal, and WR - 107 Snow Removal Standards. 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. d) 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. e) 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. f) Snow removal should be performed between the hours of 5 p.m. and 5 a.m. when the recreating public is least likely to be in the parking lot, or as directed by the landowner’s representative (which may include an Agency representative and/or a Forest Service representative). g) Equipment and operator must be available on an on-call basis with 2 hours advance notice (24 hours per day, 7 days per week). h) Snow Removal and plowing work will be done based on the above standards to ensure parking lots and roads are accessible for the recreating public. This also means often working to prepare for, or during public holidays and just before times of high peak usage, and for events that might be held if adequate snow has fallen.
