The city is divided into 11 or more snow removal zones, each with 15 to 20 miles of roadways. Most are bordered by major thoroughfares. During winter weather events, each area is assigned a truck with a plow and salt spreader.
The Street Division monitors the street sweeping contract. The contractor sweeps arterial and collector streets twice per month, the downtown area 1 time per week and residential streets 5 times per year.
