There is a very timely report at February 23 Council:  winter maintenance standards for sidewalks and municipal parking areas.  The standards identifies how resources (personnel and equipment) are to be deployed in order to deliver the service of timely clearance of snow from sidewalks and municipal parking lots.  The guidelines include priorities and timelines; by clicking here you can see the maps which accompany the report.

The guidelines demonstrate that priorities are set with very thoughtful consideration; and that the resources are being deployed very judiciously.
