When plows are out clearing the street they are simply pushing the snow to the edge of the road. With the amount of snow we get each winter the banks along the edge of the road get so high that the plow blades cannot push the snow over them. What ends up happening is that the plow compacts more snow along the sides of the street, which makes the street narrower. To address this issue that we have every year, the City deploys equipment to wing (push) back the snow banks along the edge of the streets. This process allows the plow blade to push the snow all the way to the curb and somewhat onto the boulevard.
