The minimum standard for clearing snow accumulation is:
- after becoming aware of the fact that the snow accumulation on a roadway is greater than the depth set out in the Minimum Maintenance Standards, to deploy resources as soon as practical to address the accumulation
- after the snow accumulation has ended, to address the accumulation so as to reduce the snow to a depth less than or equal to the depth set out in the Minimum Maintenance Standards within the time limit set out
The depth threshold for our roadways is 8 cm and the time limit is from 12 to 16 hours according to the minimum maintenance standards.
