The city divides storms into three classes and responds accordingly. Hover your cursor over each class to see the definition...

• Class I
• Class II
• Class III

In the event of any snowstorm, the city's first commitment is to clear the primary routes, then secondary routes — and keep them cleared.

In the case of a Class III storm (and only in this case) the city will also bring on contract equipment to clear all 260+ miles of residential streets and lanes. 

Our Task

There are 451 lane miles of primary street routes (like Colorado Blvd) in the City of Thornton. There are 195 secondary route lane miles and an additional 612 miles of streets for a total of 1,258 lane miles. Depending on the severity of the storm, the actual miles plowed and sanded are significantly more than the above figure since multiple passes could be needed to keep our major roadways open.
