Clearance of snow or ice and maintenance of the secondary road system during the winter months are primarily for the benefit of the local residents of the County. Each storm has individual characteristics and must be dealt with accordingly. The portion of the roadway improved for travel will have upon it snow and ice in a compacted condition. These conditions may be continuous, or they may be more concentrated on hills, in valleys, curves, and/or intersections. The County’s existing snow removal equipment will be utilized for this purpose. On occasion County personnel may be rendered unavailable due to the requirements of the Omnibus Transportation Employee Testing Act of 1991. Except for “emergencies” as determined by the County Engineer’s professional judgment, on a case-by-case basis, all clearance of snow or ice, sanding, salting and other maintenance respecting winter conditions shall be accomplished within the amount of money budgeted for this service and as practicable. The entire width of the portion of the road improved for travel may not be cleared of snow, ice, compacted snow, ice, or frost. Snow cleared from that part of the roadway improved for travel shall be placed on or in the adjacent shoulder, ditch, or right-of-way. Snow can be expected to accumulate adjacent to the traveled portion to the extent that a motorist’s sight distance to both the left and right may be greatly reduced or impaired. The snow removed from intersections will be piled in its corners in piles of unequal height. The lines of sight, sight distance or visibility of motorists approaching these intersections may be greatly reduced or impaired. The County shall not be responsible for snow pushed or otherwise placed on the roadway or shoulders by others. Motorists shall drive their vehicles during these conditions with additional caution and watchfulness, especially in respect to the surface of the roadway, and reduced or impaired visibility, and are advised to reduce their speed at least 25 miles per hour below that legally permitted or advised under normal conditions. In respect to roadways that have only one lane open, further extreme watchfulness and caution should be exercised by the motorists, and their speed should not exceed 10 miles per hour. During these conditions no additional warning or regulatory signs will be placed warning of impaired sight distances, visibility at intersections, road blockages, one-lane conditions, or that the road surface is slick or slippery, or what the advised speed should be.
