N.Y. High. Law § 135
The board of supervisors of any county may annually appropriate and expend such sum as it deems proper for the removal of snow from the county roads of the county, and for sanding, or otherwise treating them, for the purpose of removing the danger due to ice and snow thereon. The board shall designate the county roads from which the snow is to be removed and the work shall be conducted in a manner to be determined by the board under the direction of the county superintendent of highways.
The board may also annually appropriate and expend such sum as it deems proper for the planting of trees, the cutting and removal of noxious weeds, briers and brush within the bounds of county roads and town highways improved by county aid, and the purchase and erection of snow fences, or other structures to prevent the drifting of snow on the said roads and highways; and the county superintendent may when authorized by the board of supervisors enter lands adjacent to a county road to remove any fence or other structure which causes snow to drift in and upon such county road, and erect snow fences or other devices upon such lands to prevent the drifting of snow in or upon such county roads.
Whenever any equipment acquired by a county as provided in this section is not needed by the county, the county superintendent may lease such equipment to (a) any town or towns in the county to be used on town highways under the direction of the town superintendent, (b) or to the state commissioner of transportation.
Where lands are entered upon under the provisions of this section, the county superintendent shall agree with the owner of such lands, subject to the approval of the board of supervisors, as to the amount of damages, if any, sustained by such owner in consequence of such entry in performance of the work authorized by this section, and the amount of such damages shall be a county charge. If the county superintendent is unable to agree with such owner upon the amount of damages thus sustained, the amount thereof shall be ascertained, determined and paid in the manner that damages are so ascertained, determined and paid, where new highways are laid out and opened and the town superintendent and the land owners are unable to agree upon the amount thereof.
