Winter Weather Operations Update, February 2

The purpose of winter weather operations isn't to clean and clear streets. The goal is to restore traction to streets so that motorists can be as safe as possible. Restoring traction to streets can be a tricky business, but there are generally four ways traction can be restored to streets during winter weather:

1. Restoring traction by plowing
2. Restoring traction by using salt
3. Restoring traction by using sand
4. Restoring traction by using a combination of plowing, salting, and sanding. 

When temperatures fall below 15-degrees Fahrenheit, the salt melts ice and snow more slowly. The colder it is outside, the longer it takes salt to do its work, which impacts winter weather operations. During some storms, traction can be restored by moving snow away from roads with plows, and in other storms, traction can be restored by using only a salt treatment. In other cases, plowing a street may reduce traction - especially in neighborhoods. 

When snow becomes tightly packed, ice forms underneath. In these instances, drivers may not plow because removing the top layer of snowpack would leave a solid sheet of ice that salt treatment cannot melt quickly or efficiently. Although it seems counterintuitive, a small amount of snowpack can increase traction and keep motorists safer than they may otherwise be.

Don’t park in the street whenever possible. It is dangerous and difficult to plow streets congested with parked vehicles. Some streets may not be plowed if plows cannot safely maneuver them.

The most helpful thing residents can do to facilitate snow removal is to get their cars off the street and encourage others to do the same. Residents with no other option other than on-street parking should park as close to the curb as possible.

One of the most frequent concerns in the removal of snow from public streets is snow being pushed back into driveways during plowing operations. As plows travel along streets, the snow accumulated on the plow blade has no place to go but on the adjacent streets and in driveways. The more snow that has fallen, the greater the problem will be.

• Residents can reduce the likelihood of snow blocking their driveway by shoveling snow to the right while facing the street. Doing this will help snowplow drivers avoid carrying piles from the “upstream” side back across driveways.
• In addition, shoving or blowing snow/ice into streets may cause hazardous conditions to other drivers. Residents and property owners are encouraged to follow the directions above in both commercial and residential areas.
