Flagstaff snow plow and parking guide.
Flagstaff keeps main roads, steep hills, downtown, transit routes, and school routes open first. Smaller storms may never trigger residential plowing. From November 1 through April 1, city streets and alleys have no parking from midnight to 7 a.m., even on clear nights.

Open Arizona 511How the response unfolds
What happens before your street is finished
Flagstaff follows a local sequence. Knowing the phase explains why one road can be clear while another is still waiting.
- 1First priority
Keep the main network open
Crews repeatedly work arterials, hills, downtown, Mountain Line routes, and school bus routes.
- 2Second priority
Add neighborhood streets when qualified
Residential and other second priority streets enter the plan only when accumulation reaches the seasonal threshold.
- 3After the storm
Widen, haul, and restore drainage
Crews revisit roads, haul stored snow, clear storm drains, monitor ice, and add abrasives where needed.
Before leaving the car
Flagstaff parking rules that matter
- Do not park on a city street or alley from midnight to 7 a.m. between November 1 and April 1.
- The overnight rule is enforced whether or not snow is falling.
- A vehicle parked in violation during snow can receive a citation and may be towed.
- Read the ordinance page for the limited Coconino Avenue exception and follow every posted sign.
Resident checklist
What to do during the storm
- 1
Move the vehicle completely off city streets and alleys before midnight.
- 2
Check the month and snowfall total before expecting second priority streets to be plowed.
- 3
Use Arizona 511 for Route 66, Milton Road, West Route 66, Fort Valley Road, and other state routes.
- 4
Expect cinders rather than chemical deicer on city roads.
- 5
Keep private snow out of the roadway and allow space for repeated plow passes.
Service boundaries
Who clears what in Flagstaff
The city plow department is not responsible for every road, sidewalk, driveway, alley, or parking area.
Flagstaff Streets Section
Plows city streets by priority, applies cinders, performs cleanup, and reviews nonemergency service requests.
Arizona Department of Transportation
Maintains state routes through Flagstaff and may use deicer on roads that the city does not service.
Residents, visitors, and private operators
Keep vehicles out of the overnight route, clear private access, and avoid placing snow where it blocks city work.
If the street looks missed
Confirm the route and storm threshold first
A second priority street may not be scheduled during a smaller storm. During larger events, reports are handled by safety priority as crews work toward the city's target time.
- 1Confirm the road belongs to Flagstaff rather than ADOT or a private owner.
- 2Match the accumulation and month to the official first or second priority plan.
- 3Send the exact location through the city Request Tracker if it still qualifies for nonemergency follow up.
Local questions answered
Flagstaff snow plow FAQ
Short answers for the questions residents usually have during an active storm.
Will Flagstaff plow my residential street after any snowfall?
No. Smaller storms can remain limited to first priority streets. The threshold is lower in January and February than during the early and late parts of the snow season.
Can I park overnight when no snow is forecast?
Not on city streets or alleys during the winter ordinance hours. The midnight to 7 a.m. ban is enforced every night from November 1 through April 1.
Why are Flagstaff roads covered with cinders?
The city does not currently use chemical deicing agents. It applies cinders to hills, intersections, crossings, shaded areas, and other trouble spots for traction.
