Winter Operations Update - Friday, March 31 - Afternoon
March is going out like a lion! Periods of wet snow moved into the region and will continue through the afternoon before changing over to rain this evening. Rain will continue this evening, through the overnight and is expected to wrap up Saturday afternoon or early evening, with 20 to 25 millimetres of rainfall possible. Temperatures Friday will be cool, but above freezing, while Saturday’s forecasted temperatures are expected to reach a high of plus 12 degrees. Frigid air returns Saturday night with a sharp drop in temperature and wind chill values in the minus 20s expected. This may create icy conditions and residents are reminded to exercise caution while using all transportation networks.
The Roads and Parking Services team continue to operate 24/7 and we are ready! Supervisors will be out over the next 48 hours to monitor conditions. As the precipitation moves in, we will keep a close eye on sidewalks, roads, and the winter cycling network and deploy resources as needed.
Ahead of this rain event, we are asking residents to keep an eye on their local catch basins to ensure they are clear from any debris or remaining ice to allow water to drain from the roadway. You may report a blocked catch basin by creating an online service request by visiting Ottawa.ca or by calling 3-1-1.
This Week’s Peek at Potholes
Pothole crews continued their work on temporary repairs and this week alone, 151 crews have been assigned and since March 27, managed to fill over 12,000 potholes! This brings our year-to-date total – January 1 to March 30 – to more than 62,000 potholes filled. With 65 freeze-thaw cycles so far this season, and another one possible over the next 24 hours, crews have been busy, but they are up for the challenge!
To report a pothole on the road, let us know by visiting Ottawa.ca.
Over the weekend, supervisors will continue to monitor the transportation networks for icy conditions and localized drainage issues. Unless there is a significant change in the weather forecast, please consider this your operational update for the weekend.
Stay safe and travel with care.
When roads and sidewalks get plowed
Snow clearing is done using a road-priority system, with high-use, emergency and transit routes cleared first:
- At the start of accumulation:
- Highway 174, the Transitway, major roads and arterials.
- After the last snowflake has fallen, these routes may take 2 to 4 hours to complete.
- 2.5 centimetres accumulation:
- Sidewalks in the downtown core and the winter cycling network
- After the last snowflake has fallen, these routes may take up to 4 hours to complete
- 5 centimetres accumulation:
- Secondary roads and minor collectors such as Wall Road, Dovercourt Avenue, Donald Street, Springbrook Drive, etc.
- After the last snowflake has fallen, these routes may take up to 6 hours to complete
- 5 centimetres accumulation:
- Residential sidewalks
- After the last snowflake has fallen, these routes may take 12 to 16 hours to complete
- 7 or more centimetres of accumulation
- Residential roads and lanes such as Billings Bridge, Waverley Street, Smith Road, etc.
- After the last snowflake has fallen, these routes may take 10 to 16 hours to complete.
Timelines are suspended if a Significant Weather Event is declared as operations will be carried out based on the capacity of resources in as continuous a manner as practicable.
Plowing through a winter storm
After a severe snowstorm, operators may have to plow a street twice. Sometimes a grader or dump truck with front and wing plows will do a first pass, followed by a sand/salt truck, to clear a small amount of snow and make sanding/salting more effective.
To clear a cul-de-sac, operators will push the remaining snow to the centre or outside of the street, depending on the available area.
In the early winter, the City removes ruts that have formed on snow-packed surfaces. This keeps catch basin open and helps prevent flooding.
Significant Weather Events
What is a “Significant Weather Event”?
A “Significant Weather Event” (SWE) is defined as an approaching or occurring weather hazard with the potential to pose a significant danger to users of the highways within a municipality. Weather Hazards are determined by Environment Canada as meeting the criteria for the issuance of an alert under its Public Weather Alerting Program.
This declaration suspends the Maintenance Quality Standards (MQS) timelines required for our City to meet our winter maintenance objectives. This declaration will remain in place until the City formally declares the Significant Weather Event has ended. Once an event has ended, standard timelines for winter maintenance activities will begin.
Why would we need to declare a “Significant Weather Event”?
The intent of a declaration is to notify the public that due to the forecasted or current weather conditions, caution is to be exercised when travelling on the City’s sidewalks, pathways, roads and the winter cycling network, and that it will take longer than usual to restore them to the expected condition.
Is Ottawa the only city that declares “Significant Weather Events”?
Many cities and municipalities in Ontario declare “Significant Weather Events”. Under the Ontario Regulation 239/02, Minimum Maintenance Standards for Municipal Highways, made under the Municipal Act, 2001, as amended, municipalities have been given the authority to declare a Significant Weather Event when a weather hazard is approaching or occurring and has the potential to pose a significant hazard to users of the highways in which the municipality has authority over.
Based on the legislation, a municipality may declare a Significant Weather Event when Environment Canada has issued an alert under its Public Weather Alerting Program. The municipality must also determine that an approaching or occurring winter event locally meets the criteria for a weather hazard, and in its judgement, also poses a significant danger to users of the highway.
How will I know the City has declared a “Significant Weather Event”?
When a Significant Weather Event has been declared, the City will:
- Inform Council
- Post a notice on Ottawa.ca/winter
- Send a PSA to media
- Provide an update on the City’s Social Media accounts including Twitter and Facebook
- Update the voice recording residents hear while calling 3-1-1 with notice of the event
- Residents do not need to speak to a call centre agent in order to hear the recording
When the event has ended, the City will also post / share the notice indicating the Significant Weather Event has been lifted using the same tools.
What should a resident do when they see the City of Ottawa has declared a “Significant Weather Event”?
We will declare a Significant Weather Event when there is an occurring or expected weather hazard with the potential to pose a significant danger to users of our City’s sidewalks, pathways, roads and the winter cycling network. During such an event, residents are encouraged to limit travel to only essential trips outside of their home. Those who cannot are reminded to exercise caution based on the conditions of the transportation network, and to offer our snow clearing vehicles space to do their jobs.
During a Significant Weather Event, our winter operations will continue. We will continue to clear and treat the sidewalks, pathways, roads and winter cycling network – we just won’t complete our work within our Maintenance Quality Standards timelines.
Residents should sign up for Winter Weather Parking Ban e-Alerts to be alerted to an upcoming parking ban. A winter weather parking ban may be called at any time during the winter, including during a Significant Weather Event.
During a Significant Weather Event, all available resources will be deployed, and we will be asking residents to refrain from calling 3-1-1 or creating a service request for anything other than an emergency.
Clearing snow from your property
- Do not push snow and ice on the street, sidewalk or park.
- Keep fire hydrants free of snow.
- Use wood, plastic or fibreglass driveway markers, which should be no larger than a hockey stick.
- Open catch basins or drains in front of your property when the weather becomes mild.
- Catch basins are identified by a yellow “T” bar painted on the roadway.
A snow windrow is a pile of snow that accumulates at the end of driveways and on the sides of streets during plowing. It is the responsibility of the home owner to remove their own driveway windrows.
Snow fences reduce the build-up of drifting snow and ice on roads, and improve visibility for motorists. The City installs wood-slat snow fences or partners with local farmers for corn or tree fences.
Plant a snow fence
The City encourages landowners who plant corn to participate in the Alternative Snow Fencing Program.
In late summer, participating landowners leave six to 12 rows of standing corn parallel to the road and 20 metres from the road’s right-of-way property line. In December, landowners are paid an amount based on the market value per tonne of the unharvested corn, the yield of tonnes per acre, the actual acres standing and for spring clean-up work
In non-agricultural areas, landowners can plant trees 20 metres from the right-of-way property line.
To find out more, please call 3-1-1 (TTY: 613-580-2401).
Snow removal operations
Snowbanks on the City’s transportation network are removed or reduced in size when they begin to restrict sightlines, travel widths, or pedestrian, vehicular, and cycling traffic. Residents are responsible for snowbanks along their private driveway.
Snowbank removal operations come secondary to standard snow clearing operations (i.e., when there is a storm, and teams must plow and/or treat roads). If snowbank removal operations are underway and a storm begins or is approaching, teams may temporarily be redeployed to respond to the changing conditions. Snowbank removal operations will resume once clearing and/or treating is complete.
What to expect
Before snowbank removal operations begin, signs will be posted in the snowbanks of streets where operations are scheduled to take place:
- Parking is prohibited in areas where snow bank removal is taking place and drivers are required to abide by posted signage. Parking permit holders are not exempt from snow removal operations. Failure to remove a vehicle from a zone where temporary no stopping signs are posted will result in a ticket, and the vehicle will be towed to a nearby street.
Signs are not removed before operations begin as this would very time consuming but most importantly, too dangerous for teams to be working in front of the blades. Instead, signs are made using biodegradable material along with the snow, are blown into the trucks and are then brought to the snow storage facilities where they will be disposed of accordingly.
To keep our teams safe, signs are not removed before operations begin as it is too dangerous to be working in front of the blades.
Looking for your towed vehicle? Please call 3-1-1.
Snow clearing maintenance standards
The City aims to keep streets clear of snow for everybody's safety.
Roads are classified based on their importance to Ottawa's transportation network. When a snowstorm begins, City crews clear snow on high priority roads, main arterials and collectors.
The City of Ottawa has developed maintenance standards for snow and ice control.
Snow disposal facilities
The City’s snow disposal facilities no longer accept non-city snow from private operators. They continue to accept snow from contractors hauling snow from public property on behalf of the City of Ottawa.
Snow plow contractors – business licensing
Every snow plow contractor must obtain a snow plow contractors license.
This schedule does not apply to:
- people who clear snow with a shovel or with a manual snow-blower.
- farmers who only clear snow to help out the community.
Corn row fencing
Corn row fencing is more effective than wooden snow fences in rural areas. Prior to the winter season, farmers and the City of Ottawa enter into an agreement to participate in the program. The City compensates landowners for the pre-negotiated market value of unharvested corn.
Replacement of damaged mailboxes by snow plow
Occasionally rural roadside mailboxes are damaged or destroyed by snow plows.
- Mailboxes will be repaired or replaced as determined by the Roads Department Supervisor.
- Mailboxes damaged by the snow that comes off the wing of the snow plow will not be eligible for repair or replacement.
- Mailboxes will be replaced by something basic; do not expect to receive your original mailbox.
- Damaged posts will be replaced by a temporary post with permanent repairs undertaken in the spring after the frost is gone.
To report a damaged mailbox, call the City of Ottawa at 3-1-1 or report online at ServiceOttawa.ca.
Salt and abrasive materials (grit)
The City applies dry salt, wet salt, liquid brine and abrasive materials (such as a grit mix) on streets. Salt is spread early during a snowstorm to make a brine solution that prevents the ice from sticking to the asphalt.
To minimize salt use, rock salt is sprayed with a liquid de-icer as it is spread. This speeds up ice melting by making the salt sticky so it can adhere to the road.
Abrasive materials such as grit are used to increase traction in colder temperatures when salt is not effective.
Garbage and recycling collection during a winter storm
Place garbage containers and bags and recycling bins at the curb. Do not place them behind or on top of snow banks.
Help make sidewalks safe
To make sidewalks safe to walk on in the winter, the City provides do-it-yourself grit boxes close to steep hills and in areas where there are many pedestrians, seniors and persons using mobility devices. Residents are encouraged to spread the grit on slippery spots on sidewalks and other problem areas.
