Early Morning Friday, December 20th
Crews concentrated on the Transitway, highway 174,
arterials, collectors and priority sidewalks.
Staff were stationed at the Traffic Operations Centre
monitoring traffic and transit conditions.
Early Moring Saturday, December 21st
Precipitation changed from snow to freezing rain/ice
pellets causing operations to continue to focus on main
roads and priority sidewalks.
8
Saturday Morning (Dec 21)
Crews began plowing residential streets Saturday
morning and continued throughout the day.
Sunday Morning (Dec 22)
Focus moved back to main roads after 12 -15 additional
cm of snow/ice pellets fell.
Sunday Afternoon – Monday Morning (Dec 22-23)
As resources were freed up residential roads were
plowed and gritted for the second time in two days.
9
Clean- up included:
Following the event, intersections, bus
stops, dead ends and cul-de-sacs
were cleaned up.
Snow removal on main and residential
streets was prioritized
◦ Precedence was given to all priority
construction areas as well as roads
with substandard travel widths
Removal was completed for a second
time on most main roads due to snow
volumes
◦ Completing two removals before the
end of December is unusual
10
The breakdown of expenditures:
◦ $2,735,700 - Applying winter material to roads
◦ $782,700 - Plowing roads
◦ $873,500 - Sidewalks
◦ $7,194,800 - Snow removal
◦ Total cost - $11,787,600

Higher than average snowfall of 272cm (236 avg.)
Several large accumulations that enacted the Overnight
Parking Restriction◦ Jan 6, Jan 28, Feb 8, Feb 27/28, Nov 26/27, Dec 20/21
Meanwhile, smaller but longer duration storms also
resulted in a higher than average number of winter storm
days◦ There were 129 days with measurable precipitation versus a 20 year
average of 95 days.
Many winter events also fell on weekends or between
shifts, involving bringing staff in on overtime.
14
Large volumes of snow are
hard to manage for
everyone but particularly
older adults and those with
restricted mobility.
The older adult plan had
funded some additional grit
boxes to assist in preventing
accidents in areas with large
populations of older adults.
15
In recent years, there has been a shift in the areas
of concentration for snow removal efforts.
Traditionally, snow removal efforts are concentrated
in the core of the city. However, snow removal in
suburban areas has steadily increased.
16
Some newer suburban communities have limited
snow storage as a result of more intensive land
use
17
Certain routes have
been given a priority
status due to Ottawa
on the Move
construction projects
These priority roads have received increased levels
of service to better accommodate larger volumes of
traffic

City tax supported accounts are combined at

Surpluses in other areas will offset most of the
winter operations deficit
Any remaining deficit in winter operations will
come from the Winter Maintenance Reserve
