If your sidewalk is immediately adjacent to the road, keep the first 8 inches of the gutter clear of snow and ice.
When it gets warm outside, the melting snow will not end up pooling on your sidewalk. Ideally, everyone between your property and the closest storm sewer needs to do this to ensure the water ends up draining away. If they don't, consider clearing their gutters for them if it's not too much work.
Please also shovel all snow on your lawn not on the road so that our streets remain as clean as possible. Shovelings or pushing snow from sidewalks into roads or alleys violates municipal bylaws and results in a fine of $250, contributes to unsafe driving and walking conditions, increases the cost of providing winter road maintenance and can lead to blocked storm drains.
