First priority
Main traffic routes
Naperville begins with the streets that carry the most traffic and are most important for moving vehicles through the city.
Naperville Winter Guide
How Naperville plows city streets.
Snow removal across a city the size of Naperville happens in stages. Crews do not clear every street at once — they work through a priority system designed to keep the most important traffic routes moving first.
Here is what the City currently says about when plowing begins, how streets are prioritized, how salting fits into the operation and what residents should expect while a winter storm is still underway.
01 How it starts
Snow operations can begin before plowing does.
Naperville's winter response includes both salting and plowing, and those two operations do not necessarily begin at the same time.
According to the City, crews begin applying salt when unsafe traveling conditions are expected. Rock salt is used for smaller amounts of winter precipitation, with application amounts influenced by accumulation, temperature and traffic conditions.
Plowing begins once measurable snow has accumulated on paved surfaces and snow is still falling.
That distinction matters. During a developing storm, crews may already be treating roads before there is enough accumulation to justify a full plowing operation.
Once plowing begins, the City's goal is not to make every street look identical at the same moment. Crews work through a defined hierarchy.
Priority plowing
Not every street has the same priority.
Naperville directs resources first toward the roads that matter most to overall mobility, then progressively moves deeper into residential areas.
02
Second priority
Residential side streets
After major routes receive attention, crews move into neighborhood streets and other lower-volume residential areas.
03
Following areas
Cul-de-sacs, alleys & dead ends
These areas come later in the operation and can require slower, more specialized maneuvering because there is less room to place snow.
During the storm
Why your street can look unfinished.
A plow passing your street does not necessarily mean snow operations are finished there.
If snow is still falling, the pavement can begin accumulating again immediately after a plow passes. Blowing snow can also move back across the roadway.
Crews may need to cycle repeatedly through higher-priority roads before spending more time on lower-volume streets. The visible condition of a road therefore depends partly on where crews are in the broader citywide operation.
Salt also has limits. Naperville specifically advises residents that colder temperatures and blowing snow reduce its effectiveness, which means a plowed road can remain snow-covered or slick.
Practical takeaway
“Plowed” does not mean “bare pavement.” During active winter weather, the more realistic objective is keeping roads passable while crews continue working through the storm.
What residents should expect
A snow operation is a moving process.
Understanding the timing of the operation helps explain why conditions can change rapidly even after municipal crews have already passed through an area.
Plowing happens during the storm
The City says crews begin plowing once measurable snow has accumulated on paved surfaces and snow is still falling. A street can therefore be plowed and then accumulate additional snow before the event is over.
Salt does not work equally well in every condition
Temperature, snowfall, traffic and blowing snow all affect road treatment. Naperville specifically cautions that very cold temperatures and blowing snow can reduce salt effectiveness.
A cleared street may not look bare
The objective during an active storm is safe and passable travel. Roads can remain snow-covered or slick even after plowing, especially during ongoing snowfall or colder conditions.
Different roads can look very different
Priority, traffic volume, jurisdiction and the timing of the most recent plow pass can all affect what two nearby roads look like at the same moment.
Salting
Road treatment depends on the weather.
Salt is part of Naperville's winter operation, but it is not a guarantee of immediately dry pavement.
The City says its salt usage depends on total accumulation, temperature and traffic conditions. Those variables can change over the course of a single storm.
When conditions become colder, chemical melting becomes less effective. Continued snowfall or blowing snow can also cover treated surfaces again.
That is why the City tells drivers to slow down, allow additional travel time and give snowplows room to work even when roads have already been treated.

Open City snow-removal resources One important exception
Not every Naperville road is a City road.
A road can run through Naperville without being maintained by Naperville Public Works.
The City currently identifies several major corridors as the responsibility of IDOT, DuPage County or Will County.
That includes Route 59 and Ogden Avenue / US 34 under IDOT, as well as roads such as 75th Street and specified portions of Naperville Road, Naper Boulevard, Diehl Road, 95th Street and other corridors under county jurisdiction.

What the City asks residents to do.
01
Keep vehicles off the street
Parked cars interfere with plowing and can leave large areas of snow and ice behind.
02
Keep private snow out of the roadway
The City instructs residents to place driveway snow in the parkway rather than pushing or shoveling it into the street.
03
Give plows room
Drivers should stay back from snowplows and avoid attempting to crowd or pass equipment unnecessarily during active operations.
04
Expect driveway-apron snow
Street plowing can leave a dense ridge of snow at driveway entrances even after the driveway itself has already been cleared.
Where public plowing meets private property
The street can be clear and your driveway can still be blocked.
Municipal plows push snow toward the outside edge of the roadway. When the blade crosses a driveway opening, part of that moving snow can be deposited across the driveway apron.
That is why homeowners sometimes finish clearing a driveway only to find a dense ridge of street snow at the entrance after the municipal plow passes.
Downtown Naperville
Downtown snow sometimes has to leave downtown.
Downtown presents a different snow-removal problem because there is less room to leave accumulating snow along streets and parking areas.
Naperville Public Works removes snow piles from downtown to help keep parking spaces available, improve visibility and reduce icy pedestrian conditions.
The City says downtown snow is transported to the garden plot parking lots on West Street, west of Edward Hospital.
Most loadouts take place during the days following snowfall, although major storms can require work over several days and sometimes during nighttime hours.
City plowing FAQ
Common Naperville snow questions
These answers summarize current City guidance. During an active event, use official City resources for the latest municipal information.
When does Naperville start plowing?
The City says crews begin plowing once measurable snow has accumulated on paved surfaces and snow is still falling. Salt may be applied earlier when unsafe travel conditions are expected.
Why is my neighborhood street not plowed yet?
Naperville uses a priority system. Main traffic routes are addressed first, followed by residential side streets, with cul-de-sacs, alleys and dead ends handled later in the operation.
How long does it take Naperville to salt every City street?
The City currently states that a complete salting cycle across its street network takes approximately 4.5 hours.
Can I track Naperville snowplows?
The City provides an interactive snow-removal map showing streets that have been salted or plowed during active winter operations.
Why is my street still slick after being plowed?
Plowing removes accumulated snow but does not guarantee bare pavement. Cold temperatures, continued snowfall, blowing snow and reduced salt effectiveness can leave roads snow-covered or slippery.
Does Naperville plow Route 59 and Ogden Avenue?
No. The City identifies Route 59 and Ogden Avenue / US 34 as Illinois Department of Transportation roads. Other major roads are maintained by DuPage County or Will County.
