Where are snowplow stored?

Random question reddit - Does anyone know where snowplows are stored around town? A friend of mine had her kindergarten class interested in knowing where they are kept during off season.

Update: Major kudos to u/teenytinytaylor for both details and pictures of the city's snowplows. The kiddos loved getting to see the pictures this morning and hearing about the city's prep for the upcoming season. They also can't wait to see them in action again which I'm not too sure I share that sentiment with the ice that it would bring haha
