So far this year, Glen Ellyn's snow-removal crews have responded to 31 storms.
"In an average winter, we have 20," Hansen said.
A community the size of Glen Ellyn, population 27,000, might use 50 to 100 tons per storm. A bigger community such as Waukesha, Wis., which has about 70,000 residents, could use 300 tons or more. The same storm in Chicago would call for more than 13,000 tons.
Demand is so high that salt gets more expensive every day. Communities are trying to decide what do to. They could buy a little more salt now, when it costs twice or three times more than earlier in the season, and hope it doesn't snow too much more. Or they could wait until it does snow more and risk paying even higher prices.
In some areas, there has been so much snow that cities have had to find creative ways to stretch their supplies: spreading salt only on intersections and major roads and mixing it with sand. In Indiana's Morgan County, there is so little salt left that what is on hand will be mixed with sand and used only on the hills.
"We can only do what we can do," county engineer Larry Smith said.
In Pennsylvania's Butler County, they're trying out a product called Beet Heet, made of processed sugar beet molasses, for anti-icing purposes.
Milwaukee road crews are experimenting with liquid cheese brine, mixing it in with rock salt before it goes on the road to make the salt wetter "so it will stick in place instead of bouncing away," said Sandy Rusch Walton, a spokeswoman with Milwaukee's Public Works Department.
Elsewhere, communities have cut back.
"As the season goes along, we become stingier," said Fred Abadi, the public works director in Waukesha.
Motorists have noticed.
When Emira Palacios got into her car Tuesday, as another storm rolled in, "none of the streets had salt," she said. "It is a little scary."
Wichita has received only about 800 tons of the 3,000 tons of salt it ordered. So salt is being mixed with sand and road crews are given just enough of the mixture to cover emergency routes. When the salt runs out, road crews will use sand alone.
But sand has its limitations and can even create problems.
"Sand gives you some traction to get started, to stop, but it doesn't do any melting," said Joseph T. Pajor, deputy director of the city's public works and utilities department.
