The following is a general description of Greenfield's Snow Fighting Plan.
Step One:
When a snowstorm begins, the Public Works Department responds by sanding and salting the main roads and hill sections. Sanding these roadways serves two purposes: to keep traffic moving and to prevent the snow from bonding to the pavement.
Step Two:
Plowing operations begin when snow accumulates to approximately three (3) inches, or forecasts indicate that it will. Over 25 Town plows are called out and assigned to pre-determined routes. It takes roughly seven (7) hours to plow all 120 miles of roadway once. During a long duration storm the streets may be plowed 2 or 3 times.
Step Three:
Once snowfall has stopped and plowing is winding down, sand trucks begin post-storm sanding if necessary. Recent experience has shown that pretreating the roads before a storm generally negated the need for this second sanding, helping to reduce the costs of the operation. Main streets are salted to achieve bare pavement and residential streets with hills are sanded to improve traction. Flat streets are sanded only if icy conditions exist.
Step Four:
At midnight, once there is little traffic in the downtown area, crews are called in to clean-up downtown streets which are difficult to plow well during the day when there is heavy traffic and parked vehicles. They also clear town and school parking lots.
