Plowing is critical when a snowstorm begins and continues until snowfall subsides. Snow trucks on the road with plows up may be returning for fuel, en route to another area or the road may be too icy and could require a different type of equipment, such as a grader, for effective ice removal. If a city vehicle is able to travel down your road with two-wheel drive, the city will not send a plow.
City snow removal crews use a salt and cinder mix to melt the snow and ice. This is applied in all situations on all streets that are being maintained, as means of melting snow and providing traction; the ration is four parts cinder to one part salt to reduce corrosiveness of salt on equipment, vehicles and streets. The deicer is rock salt, a naturally occurring product that is mined in Carlsbad.
