Snow & Ice Control FAQs

Public Works sets a time-based goal depending on the severity of the winter weather. Primary and secondary roads are the main priority. The goal is to get every house within a quarter mile of a plowed and treated street after the primary and secondary roads are complete. Residential streets are plowed last. 

Level 1: Pre-treatment
Level 2: One inch or less; 24 hours
Level 3: One to six inches; 32.5 hours
Level 3: Six to ten inches; 40 hours
Level 4: More than ten inches; 48 hours
Level 5: Sustained winds of 30 mph; 48 hours

Residential streets are broken into routes. Routes are rotated so no one is always first or always last.


The goal is to have all streets plowed and treated within the stated time frame (see above FAQ) once precipitation and/or sustained winds end. For example, if more than 10 inches of snow falls and the precipitation ends at 2 a.m. on Sunday, crews will have all roads treated and plowed by 2 a.m. Tuesday.

Primary streets are major four-lane or high volume two-lane streets, such as Pryor Road, Langsford Road and Longview Road.

Secondary streets are defined as minor thoroughfares, and are typically the main streets that go into neighborhoods or subdivisions, such as Orchard Street and O'Brien Road.

Residental streets are smaller side streets and cul-de-sacs off the secondary streets such as Williow Way and Madison Street.

Rock salt: Anti-icing material and also a de-icing material
Salt brine: Anti-icing, saltwater solution used to prevent winter precipitation from bonding to the pavement
Calcium chloride mixed with rock salt: Used when temperatures drop into the teens
Beet juice mixed with brine and rock salt: Accelerates melting and helps materials adhere to the roadway

Primary Streets: Major four-lane roads or two-lane roads with high volume
Secondary Streets: Minor thoroughfares
Residential Streets: Local streets, including dead-end streets and cul-de-sacs

Crews complete pre-established routes based on priority. Primary streets are completed first, then secondary streets, and then residential streets. The main roads leading into neighborhoods are usually secondary streets, which are plowed before residential streets.

No; I-470, US-50, M-291 and M-150 along with the respective interchanges and frontage roads are generally owned and maintained by the Missouri Department of Transportation (MoDOT), 888-Ask-MoDOT (888-275-6636).

After the City has indicated it has completed plowing and treating streets, if you believe your street was missed, contact Public Works at 969-1870. It is important to note the City does not have a bare pavement policy, so snow or ice may still be packed onto the streets even after being plowed and treated. 

While residents are not legally required to move vehicles off the street, it does help plow drivers if there are fewer obstacles, so please remove vehicles, basketball hoops and trash cans when possible. We also ask residents to remain patient. Crews have more than 1,000 lane miles of streets and cul-de-sacs to plow and treat.

Snow and salt are both white and it can be hard to tell if salt has been applied. To be effective, salt needs to mix with snow which is accomplished with traffic on the street. Salt also becomes less effective in low temperatures.

Report damage to Public Works at 969.1870. During heavy snowfall it is difficult for crews to distinguish between the curb and road and some yard damage may occur.

There is not an ordinance requiring property owners to clear sidewalks. However, property owners are encouraged to clear snow for safety reasons.

The only contractors the City uses are for some public parking lots and some sidewalks around city facilities, as well as the downtown area.
