Costa told Channel 11 the city already has readjusted some routes and they will have 70-80 trucks on the roads. Another change is that drivers will now work 12-hour overlapping shifts so there's no drop in coverage.
In addition, the city's 311 center -- where residents can call to ask for streets to be plowed -- will open at 8 a.m. for at least 12 hours.

BEAVER COUNTY: PennDOT crews were gearing up hours before the storm.
The county salt stockpile was being portioned out to different sites.
PennDOT says it won't pre-treat roads because they have enough salt residue on them.
"We'll probably start a little ahead of the storm. We'll keep an eye on it and get out ahead of it," said Michael Simmons, county maintenance manager with PennDOT. "With it coming at four in the morning, we'll be within an hour or two of rush hour, so we want to make sure we stay ahead of it. We don't want to get behind the storm."
PENNSYLVANIA TURNPIKE: Trucks were gearing up at the Pennsylvania Turnpike maintenance building in Greensburg right along Route 66, loading salt into the back of their trucks and staying stocked with salt brine. CLICK HERE FOR VIDEO

All those trucks will be out on the road by 11 p.m.
The turnpike District 1 superintendent says they are mostly concerned with any ice and freezing rain that could come with this storm.
"We watch the temps very closely. We’ll use a salt brine additive to activate the salt faster; if we're below 20 degrees, we'll switch to calcium chloride," he said.

Officials say if you can avoid traveling altogether during the storm, you should. If you are out during the storm, take your time and give crews room to clear the roads.
The main focus for crews is getting to priority roads first.
“Pittsburgh region, the three parkways, Interstate 79, Route 28, I-579, those get the most attention,” said PennDOT spokesman Steve Cowan. “We want to make sure, because of the high traffic volume, that those roads are safe and passable.”
