Seven day Snow Event plan

Council approved priority system

The City sands, salts, and plows roads and select sidewalks based on a Council-approved priority system.

We know how important it is for Calgarians to get to where they want to go safely and winter driving can be challenging because of snow and icy conditions. The City keeps you moving safely by following a snow and ice control (SNIC) plan. See where crews are concentrating their efforts during a snow event on the snow updates page.

Preparing the roads for snow and ice

Even before it snows The City’s Roads crews are busy anti-icing roadways to reduce the accumulation of ice and snow on the roads when it comes. A Road Salt Management Plan is followed to improve environmental protection without compromising road safety.

Once the last snowflake falls the seven day plan begins

Day 1 

Priority One

- All Priority 1 routes are completely plowed, sanded and salted by the end of the first 24 hours once the snow has stopped.
