Snow Operations Priorities & Target Time Frames
First priority areas consist of the following:
- Main Arterials
- Major Hills
- Downtown
- Mountain Line Transit Routes
- School Bus Routes
All other streets are considered Second Priority Areas.
The policy also sets the following target plowing time frames based on the amount of snowfall received. During the months of January and February only:
- 0 to 3 inches of snow - First priority areas only
- 3 to 8 inches of snow - Second priority areas completed within 12 hours
- 8 to 12 inches of snow - Second priority areas completed within 18 hours
- Over 12 inches of snow - Second priority areas completed within 36 hours
- 0 to 4 inches of snow - First priority areas only
- 4 to 8 inches of snow - Second priority areas completed within 12 hours
- 8 to 12 inches of snow - Second priority areas completed within 18 hours
- Over 12 inches of snow - Second priority areas completed within 36 hours
Cindering Procedures
Cinders are applied to major hills, signalized intersections, railroad crossings, shaded areas, problem areas, and stop signed intersections. We limit the use of cinders in residential areas and flat roads. Cinders must be reapplied frequently due to traffic pushing the cinders into the snow/ice, crushing, or blowing off the roadway.
Deicing Agents
The City of Flagstaff does not currently use chemical deicing agents. ADOT crews may apply de-icer on state routes including Route 66, Milton, West Route 66 and Fort Valley Road.
Snow Operations Procedures
Continued post storm clean-up efforts include revisiting areas for additional snow removal and hauling operations, storm drain clearing, ice monitoring and periodic application of additional abrasives (especially in shaded areas or on hills), and community sweeping and clean-up after each storm event to help clear abrasives/residual storm effects.
The fleet operated by the Streets section includes (20) plow trucks, (2) six -wheel spreader trucks, (8) road graders, (3) tractor-trailers for hauling operations, (5) loaders, (2) bobcat toolcats, and (1) truck mounted snow thrower.
During all weather events, there are three (3) critical considerations for the Streets Section: Timing, Texture (Precipitation Type), and Temperature.
The timing of snow storms can create challenges. If the City receives snow right before the morning or evening rush hours, it can be difficult to keep first priority routes open/passable. Depending upon the amount of accumulation, approximately 4-12 hours are required to plow and cinder the first priority streets one (1) time. Time is the most important element in providing efficient and safe snow operations.
If you have questions about snow operations in the City of Flagstaff call the Public Works Office at (928) 213-2100 during normal business hours.
