All the residential streets will be plowed when the City calls in the contractor to plow all the residential streets. The contract divides the City into three sections, so that the contractor can work on each of the three sections simultaneously. The residential contract typically takes two to three days. The determination of when to call in the residential snowplow contractor is based on road conditions, depth of snowfall, and future weather forecast. The contractor can typically prepare their equipment and get a crew lined up within 12 hours after the call is made by the city. The weather does not always play fair, and sometimes the holidays make it difficult for the contractor to get a crew lined up.
