Normal procedure is not to cover sidewalk. Certain conditions may result in snow from the road covering sidewalks. This has been logged as SRQ2014-000182 and forwarded to Transportation to review.

Notice the size of the windrow on the non sidewalk side dies not make sense guess sidewalks provide more storage areas

In preparation for the next snow season, we’re tidying up old issues in the system. Thank you for reporting online.
