Why not remove the snow when plowing the core area?
This would greatly increase the time required to achieve the goal of having all streets open for travel and emergency access. The priority is to use equipment in plowing streets as quickly as possible and then focus on clearing parking spaces and sidewalks.
Why does it seem some snowfalls are hauled immediately and some are left a day before starting?
If the snow stops falling during the day and all streets have seen the last pass of the plows by the evening, staff and equipment resources may be able to start hauling at midnight and have some parking spots cleared by morning. If the snow stops falling late at night or early in the morning, crews will wait to start the first hauling cycle until the following evening to reduce the impact on busy public traffic periods.
Why is snow not hauled from parking areas 24-hours a day?
Winter parking restrictions are in place from 11 p.m. until 6 a.m. This period of time is used to haul snow out of the parking spaces with some snow piled for later removal during daylight hours. Staffing and operational logistics require having a short period of downtime in the early evenings to refresh the resources. PLEASE NOTE: In addition to overnight parking restrictions, motorists should also be aware that under the Provincial Highway Traffic Act and the City Traffic Bylaw, vehicles can be removed from the roadway at any time should they be parked in such a manner that the vehicle impedes the removal of snow from the roadway. Motorists should avoid parking vehicles on City streets during or shortly after a heavy snowfall when roadways are not cleared to the curb and the snow alert for snow clearing and de-icing has been activated.
Why are sidewalks not cleared as well as streets?
The machines used to clear sidewalks don't move as fast as street plows. Snow and ice doesn't melt on sidewalks like it does on the dark pavement, which absorbs sunlight. Vehicle traffic on streets helps melt ice and snow, but foot traffic packs it down on sidewalks, making it harder to remove.
Why not move parking meters to the back of the sidewalk to make it easier to clear parking spaces?
The City has tried this in the past, but it was more difficult to tell which meter was assigned to which angled parking space and merchants were concerned about meters blocking store doors and windows.
Why is snow sometimes left between on-street parking spaces and the sidewalk?
Some snow may be left at the edge of a parking spot near the curb because plow drivers have to be careful not to damage curbs, parking meters, utility poles, etc. The City strives to provide priority service to clear ice and snow in disability parking spaces.
Why does equipment break down at the start of the season?
Crews prepared plow equipment for each season, but the first time it's used in real snow, bolts or hydraulic lines may fail under the pressure. The season's first snowfall - which is usually heavy and wet - tends to reveal weak parts that weren't visually obvious.
Why do the plows sometimes rip up the street-shoulder areas?
Plow operators are attempting to accomplish many goals, often in adverse conditions. It is desired to have the plow blades scrape as close as possible to the street asphalt that slopes from centerline to edge, but not have the plow blade catch the grass. The plow is also attempting to push snow back off the paved surface to allow for full vehicle width and storage of snow in the next weather-related event. When frost has penetrated the ground in mid-winter, a plow blade may more easily bounce off the frozen surface. But in first snowfall or spring thaw conditions, the damage to edge of the right-of-way can be more common.
Where should plow markers be located to assist in street marking?
Plow markers should be set one meter (1 M) off the edge of the paved surface in uncurbed areas to allow for plow blade clearance and plowing of the full asphalt width. The first snowfall often presents operators with a flat, white surface and plow markers are appreciated in assisting them to determine the edge of the asphalt. Over the course of a winter, the snowbanks may become significant enough to help mark the street alignment.
