The City of St. Louis sends fifty or so plow trucks out before, during, and after winter storms to clear major streets, commercial districts, hospitals, fire houses, transit stops, well-traveled dangerous spots, and - in later passes - secondary streets. They do not generally plow residential and tertiary roads - as you know, if you live on one. Unless there is a particularly hazardous condition or an extended streak of cold, we let the warming weather handle that. If you come upon such a condition, let the Citizen Service Bureau know.

There are almost 2,000 lane miles in the city limits. An extended clean-up storm costs up to $300,000 in labor and supplies. A much smaller storm like this one will cost less.
The Streets crews are only the most visible part of the City's efforts during bad weather. The Departments of Human Service and Health, the Metropolitan Police Department, and the Fire Department work hard to keep residents warm and safe.
